Description

Technical Field

[0001] The invention belongs to the field of building decoration, in particular to a PVC wood-plastic board. Background Art

[0002] Wood plastic board is a new type of environmentally friendly wood plastic composite material product. It is mainly made of wood (wood cellulose, plant cellulose) as the basic material and thermoplastic polymer materials (plastics) and processing aids. After being evenly mixed, it is heated and extruded by mold equipment to form a high-tech green environmentally friendly material. It has the performance and characteristics of both wood and plastic. It is a new type of environmentally friendly high-tech material that can replace wood and plastic. Wood plastic board is a board made of wood plastic composite material. It has the same processing characteristics as wood. It can be sawed, drilled and nailed with ordinary tools. It is very convenient and can be used like ordinary wood. At the same time, it has the wood feel of wood and the water-resistant and anti-corrosion properties of plastic, making it an excellent and very durable outdoor waterproof and anti-corrosion building material.

[0003] Since the wood-plastic board always contains a certain amount of wood components, and the cellulose and hemicellulose in the wood have good water absorption, when the wood-plastic board is wetted by water or immersed in water for a short period of time during use, the hydrophobic plastic component in the wood-plastic board can block the erosion of the water flow on the wood-plastic board, and produce a certain waterproof effect. However, in the case of long-term liquid immersion, the wood fiber component in the wood-plastic board gradually absorbs water, causing the wood-plastic board to expand and deform, resulting in deformation and damage of the wood-plastic board, affecting the normal use of the wood-plastic board.

[0004] There are also some technical solutions for wood-plastic flooring in the prior art. For example, Chinese patent application No. 201320502929.5 discloses a wood-plastic flooring. The wood-plastic substrate of the technical solution enhances the overall rigidity of the wood-plastic substrate by setting the first rigid layer and the second rigid layer, thereby improving the bending resistance of the wood-plastic substrate, thereby greatly reducing the probability of damage to the wood-plastic substrate and increasing the service life of the wood-plastic substrate. However, the technical solution does not solve the problem that when water flows into the cooling layer of the through hole and the round tube and causes long-term backlog, water flows into the gap of the board, so that the board is immersed for a long time, the wood fiber in the board absorbs water and expands, thereby causing the board to expand and deform, resulting in damage to the board and reduced aesthetics; at the same time, because the board in the technical solution is laid in the bathroom, when the water fills the grooves on the surface of the floor, the anti-slip effect of the wood-plastic floor will be greatly reduced. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art and solve the problem that when the wood-plastic board is installed and used in a humid environment, such as a bathroom, the wood-plastic board is in a humid and water-immersed state for a long time, the waterproofness of the wood-plastic board is poor, which easily causes the board to absorb moisture and deform, affecting the normal use of the board. At the same time, since the wood-plastic board is in a humid state for a long time, the anti-slip effect of the wood-plastic board is affected, resulting in the poor anti-slip performance of the wood-plastic board, the PVC wood-plastic board of the present invention comprises a surface layer and a main body layer, the lower surface of the surface layer is fixedly connected to the main body layer by glue, the upper surface of the surface layer is provided with a groove, the side of the surface layer is fixedly connected to a rubber layer, and the opposite sides of the main body layer are fixedly connected A snap-fit ​​structure is provided, and the snap-fit ​​structure includes a snap-fit ​​slot and a snap-fit ​​block. A snap-fit ​​slot is provided on the left side of the main body layer, and a connecting snap-fit ​​block matched with the snap-fit ​​slot is fixedly connected on the right side of the main body layer. The length of the snap-fit ​​block is less than the depth of the snap-fit ​​slot plus the thickness of the rubber layer. A fixed slot is provided inside the snap-fit ​​slot, and the fixed slot is communicated with an end of the snap-fit ​​slot close to the snap-fit ​​block. A magnet No. 1 is fixedly connected to one end of the fixed slot away from the snap-fit ​​slot, and a movable slot is provided at one end of the snap-fit ​​block away from the surface layer, a spring is fixedly connected inside the movable slot, and a magnet No. 2 is fixedly connected to the other end of the spring, and the main body of the magnet No. 2 is located in the movable slot, and the magnetism of the magnet No. 1 is different from that of the magnet No. 2.

[0006] During operation, the card block in the locking structure is inserted into the card slot of the main layer. Since the length of the card block is less than the depth of the card slot plus the thickness of the rubber layer, it is necessary to squeeze it in the direction of the card slot during splicing so that the rubber layers between the boards are tightly attached. When the rubber layer is squeezed in the direction of the card slot, the rubber layer is deformed by the squeezing on both sides, which makes the gap between the boards smaller. The rubber layers on adjacent wood-plastic boards fit more closely, reducing the possibility of water seeping into the gap between the boards, and improving the waterproof effect between the boards to a certain extent. When the card block reaches the inside of the card slot, the No. 2 magnet on the card block is affected by the different magnetic properties of the No. 1 magnet in the card slot, and the No. 2 magnet moves into the fixed slot, and finally attracts the No. 1 magnet fixedly connected to the inside of the fixed slot, so that the splicing between the boards is completed. The surface layer and the main layer are made of the same material, and the surface layer is thinner than the main layer. The surface layer mainly produces an anti-slip and waterproof effect, and the main layer mainly bears the external force.

[0007] Preferably, an elastic cavity is provided inside the rubber layer, an elastic sheet is fixedly connected inside the elastic cavity, and the raised portion of the elastic sheet contacts the inner wall of the elastic cavity; during operation, since the rubber layer is not easy to shrink when the plates are squeezed against each other, the difficulty of installing the plates is increased. When the plates are clamped together, since the elastic cavity is provided inside the rubber layer, the thickness of the rubber layer is reduced, so that the elastic cavity provides a certain deformation amount when the plates are squeezed, the resistance encountered by the rubber layer during squeezing is reduced, the difficulty of installation is reduced, the rubber layers of the two plates are ensured to be in close contact with each other, and the water seepage in the gap between the plates is reduced; at the same time, the raised portion of the elastic sheet contacts the inner wall of the elastic cavity, and after the rubber layer is deformed, it is affected by the elastic restoring force of the elastic sheet itself inside the elastic cavity, so that the rubber layer has a greater tendency to restore its own state, ensuring that the rubber layers on the two adjacent plates can be in close contact with each other, reducing the influence of thermal expansion and contraction caused by the weather on the wood-plastic plate.

[0008] Preferably, a metal mesh is laid inside the surface layer, and the surface layer is divided into an upper and lower layer, which are fixedly connected by epoxy resin soft glue, and the metal mesh is buried between the upper and lower layers of the surface layer; when working, the metal mesh is made of elastic metal and has good elasticity, which can improve the strength of the surface layer and reduce the possibility of damage to the surface layer. At the same time, when the wood-plastic board is damaged and deformed due to heavy objects, the metal mesh has a reinforcing effect on the damaged part of the surface layer, avoiding the damaged part of the surface layer from detaching and affecting the aesthetics of the surface layer. At the same time, through the elasticity of the metal mesh, the damaged part of the surface layer can be restored to its original position, thereby ensuring the integrity of the surface layer as much as possible, reducing the possibility of moisture entering from the damaged part of the surface layer, ensuring the normal use of the surface layer, and improving the aesthetics of the surface layer.

[0009] Preferably, mounting holes are evenly formed at the portion of the surface layer away from the groove, and anti-skid columns are fixedly connected inside the mounting holes; when working, the anti-skid columns are made of rubber material, and the friction generated by the rubber increases when it contacts the moving object. When the surface layer is subjected to a downward squeezing force, the surface layer deforms slightly, thereby causing the anti-skid column to contact the surface of the object, thereby increasing the friction between the anti-skid column and the object, thereby increasing the anti-skid coefficient between the anti-skid column and the object.

[0010] Preferably, a convex rod is fixedly connected to the upper surface of the main layer, and the position of the convex rod corresponds to the anti-skid column inside the surface layer. An oblique groove is provided on the lower surface of the surface layer, and the surface layer and the main layer are fixedly connected by glue. During operation, the surface layer and the main layer are fixedly connected by epoxy resin soft glue. The epoxy resin soft glue has good elasticity and has little effect on the deformation of the material itself after bonding, and the colloid will not fall off. When the surface layer is deformed, the force-bearing part squeezes the convex rod in the main layer downward. Since the convex rod is fixedly connected to the upper surface of the main layer, and the position of the convex rod corresponds to the anti-skid column inside the surface layer; when the convex rod is subjected to downward squeezing force, the upper side of the convex rod subjected to the interaction of the forces will be subjected to an upward reaction force, thereby squeezing the anti-skid column to form a convex point on the surface of the plate, thereby making the anti-skid column contact with the surface of the object more closely, increasing the friction coefficient between the object and the plate, and improving the friction between the two, thereby improving the anti-skid coefficient of the plate.

[0011] Preferably, a layer of beeswax is coated on the surface of the board, and after the beeswax is coated on the surface of the board, the board is sent to a vacuum drying chamber for drying for 30 minutes; during operation, a layer of beeswax is applied on the surface of the board, and after the application is completed, the board is sent to a vacuum chamber for negative pressure heating and drying. Since the manufacturing materials of the wood-plastic board are generally plastic and wood powder plus various additives, they are water-cooled and cut after high-temperature extrusion. During the extrusion process, the wood powder and the plastic are fused with each other at high temperature, but there are still small gaps between the wood powder and the plastic after high-temperature extrusion and fusion, and the waterproof performance of the board is not up to standard, so a layer of beeswax needs to be applied on the surface of the board, so that the beeswax enters the gap under the influence of negative pressure heating in the vacuum chamber, thereby improving the waterproof effect of the board.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The PVC wood-plastic board of the present invention is provided with a rubber layer that needs to be squeezed in the direction of the card slot when being spliced, so that the rubber layers between the boards are closely attached. When the rubber layer is squeezed in the direction of the card slot, the rubber layer is not easy to shrink during squeezing, which leads to an increase in the difficulty of installing the boards. When the boards are clamped together, an elastic cavity is provided inside the rubber layer, so that the thickness of the rubber layer is reduced. The elastic cavity provides a certain amount of deformation when the boards are squeezed, so that the resistance encountered by the rubber layer during squeezing is reduced, and the difficulty of installation is reduced. It is ensured that the rubber layers are closely attached to each other, so that the gap between the boards becomes smaller, and the situation of water seepage in the gap between the boards is reduced; at the same time, the convex part of the elastic sheet contacts the inner wall of the elastic cavity, and after the rubber layer is deformed, it is affected by the elastic restoring force of the elastic sheet itself in the elastic cavity, so that the rubber layer has a greater tendency to restore its own state, so that the rubber layers on the two adjacent boards can be closely attached to each other, and the influence of thermal expansion and contraction caused by the weather on the wood-plastic board is reduced.

[0014] 2. The PVC wood-plastic board described in the present invention has a surface layer that will produce a certain amount of deformation when it is subjected to a downward extrusion force. When the surface layer is deformed, the force-bearing part downwardly squeezes the convex rod in the main layer. Since the convex rod is fixedly connected to the upper surface of the main layer, and the position of the convex rod corresponds one-to-one to the anti-skid column inside the surface layer; when the convex rod is subjected to a downward extrusion force, the upper part of the convex rod subjected to the force interaction will be subjected to an upward reaction force, thereby squeezing the anti-skid column to form a convex point on the surface of the board, thereby making the anti-skid column contact with the surface of the object, thereby increasing the friction between the anti-skid column and the object, thereby increasing the anti-skid coefficient between the anti-skid column and the object.

[0015] 3. The PVC wood-plastic board described in the present invention is prepared by applying a layer of beeswax on the surface of the board, and then sending the board into a vacuum chamber for negative pressure heating and drying. Since the manufacturing materials of the wood-plastic board are generally plastic and wood powder with various additives, which are extruded at high temperature and then water-cooled to form and cut, the wood powder and the plastic are fused with each other at high temperature during the extrusion process. However, there are still small gaps between the wood powder and the plastic after high-temperature extrusion and fusion, and the waterproof performance of the board does not meet the standard. Therefore, a layer of beeswax needs to be applied on the surface of the board so that the beeswax enters the gap under the influence of negative pressure heating in the vacuum chamber to improve the waterproof effect of the board.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] like Figures 1 to 5 As shown, the PVC wood-plastic board of the present invention comprises a surface layer 1 and a main body layer 2, wherein the lower surface of the surface layer 1 is fixedly connected to the main body layer 2 by glue, the upper surface of the surface layer 1 is provided with a groove 3, the side of the surface layer 1 is fixedly connected to a rubber layer 4, the opposite sides of the main body layer 2 are fixedly connected to a clamping structure 5, the clamping structure 5 comprises a clamping groove 51 and a clamping block 52, the left side of the main body layer 2 is provided with a clamping groove 51, the right side of the main body layer 2 is fixedly connected to a connecting clamping block 52 adapted to the clamping groove 51, and the length of the clamping block 52 is less than the length of the clamping groove 51. 1 plus the thickness of the rubber layer 4, a fixed groove 53 is provided inside the slot 51, and the fixed groove 53 is communicated with one end of the slot 51 close to the card block 52, and one end of the fixed groove 53 away from the slot 51 is fixedly connected to a No. 1 magnet 54, and an active groove 55 is provided at one end of the card block 52 away from the surface layer 1, and a spring 56 is fixedly connected inside the active groove 55, and the other end of the spring 56 is fixedly connected to a No. 2 magnet 57, and the main body of the No. 2 magnet 57 is located in the active groove 55, and the magnetic properties of the No. 1 magnet 54 and the No. 2 magnet 57 are different.

[0025] When working, the card block 52 in the card structure 5 is inserted into the card slot 51 of the main body layer 2. Since the length of the card block 52 is less than the depth of the card slot 51 plus the thickness of the rubber layer 4, it is necessary to squeeze it in the direction of the card slot 51 during splicing to make the rubber layers 4 between the boards close together. When squeezing the rubber layer 4 in the direction of the card slot 51, the rubber layer 4 is squeezed on both sides and deformed to reduce the gap between the boards. The rubber layers 4 on adjacent wood-plastic boards are more closely attached, which reduces the possibility of water infiltration into the gap between the boards, to a certain extent. The waterproof effect between the plates is improved; when the block 52 reaches the inside of the slot 51, the No. 2 magnet 57 on the block 52 is affected by the different magnetic properties of the No. 1 magnet 54 in the slot 51, and the No. 2 magnet 57 moves into the fixed slot 53, and finally attracts the No. 1 magnet 54 fixedly connected to the inside of the fixed slot 53, so that the plates are spliced ​​together; the surface layer 1 and the main layer 2 are made of the same material, and the surface layer 1 is thinner than the main layer 2. The surface layer 1 mainly produces an anti-slip and waterproof effect, and the main layer 2 mainly bears the external force.

[0026] As an embodiment of the present invention, an elastic cavity 41 is provided inside the rubber layer 4, and an elastic sheet 42 is fixedly connected inside the elastic cavity 41, and the convex part of the elastic sheet 42 contacts the inner wall of the elastic cavity 41; during operation, since the rubber layer 4 is not easy to shrink when the plates are mutually squeezed, the installation difficulty between the plates is increased. When the plates are clamped together, since the elastic cavity 41 is provided inside the rubber layer 4, the thickness of the rubber layer 4 is reduced, so that the elastic cavity 41 provides a certain deformation amount when the plates are squeezed, so that the resistance encountered by the rubber layer 4 during squeezing is reduced, the installation difficulty is reduced, and the rubber layers 4 of the two plates are ensured to be closely attached to each other, and the water seepage in the gap between the plates is reduced; at the same time, the convex part of the elastic sheet 42 contacts the inner wall of the elastic cavity 41, and after the rubber layer 4 is deformed, it is affected by the elastic restoring force of the elastic sheet 42 itself inside the elastic cavity 41, so that the rubber layer 4 has a greater tendency to restore its own state, ensuring that the rubber layers 4 on the two adjacent plates can be closely attached to each other, and reducing the influence of thermal expansion and contraction caused by the weather on the wood-plastic plate.

[0027] As an embodiment of the present invention, a metal mesh 61 is laid inside the surface layer 1, and the surface layer 1 is divided into an upper and lower layer, and the upper and lower layers are fixedly connected by epoxy resin soft glue, and the metal mesh 61 is buried between the upper and lower layers of the surface layer 1; when working, the metal mesh 61 is made of elastic metal and has good elasticity, which can improve the strength of the surface layer and reduce the possibility of damage to the surface layer 1. At the same time, when the wood-plastic board is damaged and deformed due to heavy objects, the metal mesh 61 has a reinforcing effect on the damaged part of the surface layer 1, avoiding the damaged part of the surface layer 1 from detaching and affecting the aesthetics of the surface layer 1. At the same time, through the elasticity of the metal mesh 61, the damaged part of the surface layer 1 can be restored to its original position, thereby ensuring the integrity of the surface layer 1 as much as possible, reducing the possibility of moisture entering from the damaged part of the surface layer 1, ensuring the normal use of the surface layer 1, and at the same time, improving the aesthetics of the surface layer 1.

[0028] As an embodiment of the present invention, the portion of the surface layer 1 away from the groove 3 is evenly provided with mounting holes 62, and an anti-skid column 63 is fixedly connected inside the mounting hole 62; when working, the anti-skid column 63 is made of rubber material, and the friction force generated by the rubber when it contacts with a moving object increases. When the surface layer 1 is subjected to a downward squeezing force, the surface layer 1 is slightly deformed, thereby causing the anti-skid column 63 to contact the surface of the object, thereby increasing the friction force between the anti-skid column 63 and the object, thereby increasing the anti-skid coefficient between the anti-skid column 63 and the object.

[0029] As an embodiment of the present invention, the upper surface of the main body layer 2 is fixedly connected with a convex rod 64, and the position of the convex rod 64 corresponds to the anti-slip column 63 inside the surface layer 1. The lower surface of the surface layer 1 is provided with an inclined groove 65, and the surface layer 1 and the main body layer 2 are fixedly connected by glue. When working, the surface layer 1 and the main body layer 2 are fixedly connected by epoxy resin soft glue. The epoxy resin soft glue has good elasticity and has little effect on the deformation of the material itself after bonding. The colloid will not fall off. When the surface layer 1 is deformed, the force-bearing part moves to The convex rod 64 in the lower extruded main body layer 2 is fixedly connected to the upper surface of the main body layer 2, and the position of the convex rod 64 corresponds one-to-one with the anti-skid column 63 inside the surface layer 1; when the convex rod 64 is subjected to a downward extrusion force, the upper part of the convex rod 64 will be subjected to an upward reaction force due to the interaction of the forces, thereby squeezing the anti-skid column 63 to form a convex point on the surface of the plate, thereby making the anti-skid column 63 more closely contact with the surface of the object, increasing the friction coefficient between the object and the plate, and improving the friction between the two, thereby improving the anti-skid coefficient of the plate.

[0030] As an embodiment of the present invention, a layer of beeswax is coated on the surface of the board. After the beeswax is coated on the surface of the board, it is sent to a vacuum drying chamber for drying for 30 minutes. During operation, a layer of beeswax is applied on the surface of the board, and after the application is completed, it is sent to a vacuum chamber for negative pressure heating and drying. Since the manufacturing materials of the wood-plastic board are generally plastic and wood powder plus various additives, they are water-cooled, formed and cut after high-temperature extrusion. During the extrusion process, the wood powder and the plastic are fused with each other at high temperature, but there are still small gaps between the wood powder and the plastic after high-temperature extrusion and fusion, and the waterproof performance of the board is not up to standard, so a layer of beeswax needs to be applied on the surface of the board, so that the beeswax enters the gap under the influence of negative pressure heating in the vacuum chamber, thereby improving the waterproof effect of the board.

[0031] How it works:

[0032] During normal operation, the card block 52 in the card structure 5 is inserted into the card slot 51 of the main body layer 2. Since the length of the card block 52 is less than the depth of the card slot 51 plus the thickness of the rubber layer 4, it is necessary to squeeze it in the direction of the card slot 51 during splicing, so that the rubber layer 4 between the plates is tightly attached, and at the same time, the elastic sheet 42 inside the elastic cavity 41 is bent toward the plate; when the card block 52 reaches the inside of the card slot 51, the second magnet 57 on the card block 52 is affected by the different magnetic properties of the first magnet 54 in the card slot 51, and the second magnet 57 moves into the fixed slot 53, and finally attracts the first magnet 54 fixedly connected to the inside of the fixed slot 53, so that the splicing between the plates is completed;

[0033] During use, the surface of the plate will be subjected to a certain amount of extrusion, thereby generating a certain amount of deformation. Since the surface layer 1 and the main body layer 2 are fixedly connected by epoxy resin soft glue, when the surface layer 1 is deformed, the force-bearing part presses the convex rod 64 in the main body layer 2 downward. Since the convex rod 64 is fixedly connected to the upper surface of the main body layer 2, when the convex rod 64 is subjected to downward extrusion force, the upper part of the convex rod 64 subjected to the mutual interaction of the forces will be subjected to an upward reaction force, thereby squeezing the anti-skid column 63 to form a convex point on the surface of the plate, and then the anti-skid column 63 is in contact with the surface of the object;

[0034] The metal mesh 61 is made of elastic metal and has good elasticity. It can improve the strength of the surface layer and reduce the possibility of damage to the surface layer 1. At the same time, when the wood-plastic board is damaged and deformed due to heavy objects, the metal mesh 61 has a reinforcing effect on the damaged part of the surface layer 1 to prevent the damaged part of the surface layer 1 from detaching and affecting the aesthetics of the surface layer 1. At the same time, through the elasticity of the metal mesh 61, the damaged part of the surface layer 1 can be restored to its original position, the integrity of the surface layer 1 is guaranteed as much as possible, and the possibility of moisture entering from the damaged part of the surface layer 1 is reduced; a layer of beeswax is applied on the surface of the board, and after the application is completed, it is sent into a vacuum chamber for negative pressure heating and drying, so that the beeswax enters the gap under the influence of negative pressure heating in the vacuum chamber, thereby improving the waterproof effect of the board.

When the surface layer (1) is subjected to a downward squeezing force, the surface layer (1) is slightly deformed, thereby causing the anti-skid column (63) to contact the surface of the object, thereby increasing the friction force between the anti-skid column (63) and the object, thereby increasing the anti-skid coefficient between the anti-skid column (63) and the object.
