A layer of plastic film can also be composited on the inner wall of the insulation board, and a decorative surface is pasted on the outside of the insulation board.

[0004] Regarding the above-mentioned related technologies, the base is an ordinary floor. The inventor believes that the base of the shower room is in direct contact with the ground. The cold ground in winter causes the base to be colder, and the user's feet will feel cold and uncomfortable when taking a shower. The heat in the shower room is also easily dissipated from the base, which needs to be improved. Summary of the invention

[0005] The present application provides a shower room base and a processing technology thereof. The shower room base is provided with a heat-insulating material layer to reduce heat loss, provide a comfortable feel to the foot, and facilitate production and manufacturing.

[0006] The present application provides a shower room base, which adopts the following technical solution: The shower room base comprises a bottom plate, a core plate fixed on the bottom plate, and a surface layer wrapped around the top surface of the core plate and the outside of the side wall. Drain holes are arranged through the surface layer, the core plate and the bottom plate. The material of the core plate is XPS board or ABS plastic honeycomb board.

[0007] By adopting the above technical solution, the surface layer is set to improve the comfort of stepping; by setting the core board, its good thermal insulation performance reduces heat transfer, avoids the user's feet from being cold and uncomfortable in winter, and also reduces the heat loss in the shower room, which is more energy-efficient. The bottom plate, as the bottom material of the shower room base, has high strength, can provide stable support, and is easy to install on the ground.

[0008] Optionally, glass fibers are embedded in the surface layer, and the glass fibers are located close to the core board.

[0009] By adopting the above technical solution, the glass fiber is used to improve the inner strength of the surface layer and improve the firmness of the surface layer after curing.

[0010] Optionally, the top surface of the surface layer is concave, the lowest point of the concave is located at the drainage hole, and the shape of the top surface of the core plate corresponds to the shape of the concave surface layer; The material of the surface layer is gel coat or ceramic plate or SMC; The material of the bottom plate is any one of cement board, ABS plastic board, SMC and fiberboard.

[0011] By adopting the above technical solution, the concave shape makes it easier for water on the base to gather at the drainage hole, thereby facilitating rapid drainage.

[0012] On the other hand, the present application provides a processing technology for a shower room base, which adopts the following technical solution: The processing technology of the shower room base is used to process the above-mentioned shower room base, comprising the following steps: Step S1, making the surface layer: Step S11: Place the mold with the opening facing upward, make a surface layer on the mold, and cure for 8-12 minutes; Step S2, making the inner core board: Step S21: cutting and forming the core board and prefabricating the bottom board; Step S22: The core board and the bottom board are compounded with glue, the core board and the bottom board are combined to form an inner core board, and pressed by a cold press for 0.5-1.5 hours; Step S23: sending the composite inner core board into a hot press to press the arc for 0.5-1.5 hours; Step S24: drilling holes to form drainage holes; Step S3, combining the surface layer and the inner core board: Step S31: After demoulding the surface layer, cut the edge, place the inner core board on the surface layer, and compound the two by glue dripping.

[0013] By adopting the above technical solution, the production and processing of the shower room base is completed. The hot pressing effect of the hot press machine facilitates the plastic deformation of the core board, thereby forming a surface shape that fits the surface layer. The melting effect of the core board by heating greatly reduces the rebound deformation of the core board after the pressing is completed, making the size of the core board accurate.

[0014] Optionally, step S12 is further included after step S11: sprinkling glass fiber for reinforcement for 1.5-2.5 minutes, and curing the surface layer for another 10-20 minutes.

[0015] By adopting the above technical solution, the surface layer is not completely solidified when the glass fibers are sprinkled, so the glass fibers are embedded in the surface layer under the action of gravity, thereby improving the overall strength of the surface layer and improving the tear resistance. After the surface layer is completely solidified, part of the glass fibers are exposed outside the surface layer.

[0016] Optionally, in step S21, the core board is cut into shape by hot cutting; Before the glue-drip compounding in step S31, a guide groove for the glue to enter is provided on the surface of the inner core board.

[0017] By adopting the above technical solution, physical cutting is combined with the melting effect of high temperature on the core board, so that the cutting process is more efficient, burrs on the edge of the core board are avoided, and the deformation of the core board during the cutting process can be reduced; On the one hand, the guide groove facilitates the discharge of air between the inner core board and the surface layer to prevent bubbling. On the other hand, glue enters the guide groove and forms reinforcing ribs after solidification to improve the structural strength.

[0018] Optionally, the method further includes step S32: using a vacuum device to press the inner core board and the surface layer tightly for 2-4 minutes.

[0019] By adopting the above technical solution, the vacuum equipment is started, and the vacuum suction force is used to expel the air between the surface layer and the core board, thereby preventing bubbles from affecting the firmness of the bonding.

[0020] Optionally, in step S32, a pressing film is provided on the top of the vacuum equipment, the interior of the vacuum equipment is connected to a vacuum pump, a shower room base is placed in the vacuum equipment with the surface layer facing upward, and the force of the pressing film acts downward on the surface layer.

[0021] By adopting the above technical solution, the surface layer is pressed by a pressing film. Due to its flexibility, the pressing film can avoid damage to the surface layer on the one hand, and can reliably contact with the surface layer on the other hand, and the surface contact area is large, so that the pressure is uniform.

[0022] Optionally, the method further includes step S33: standing for 20-28 hours to complete the production of the shower room base; In step S11, the spray coat forms a surface layer and then cures for 10 minutes; In step S22, the core plate and the bottom plate are combined to form an inner core plate, which is pressed by a cold press for 2 hours; In step S23, the composite inner core board is sent to a hot press and pressed for 2 hours; In step S12, glass fiber is sprinkled for reinforcement for 2 minutes, and the surface layer is cured for another 15 minutes; In step S32, the inner core board and the surface layer are pressed tightly by vacuum equipment for 3 minutes.

[0023] By adopting the above technical solution, the product can be fully cured by standing for 20-28 hours.

[0024] Optionally, in step S11, a mesh plate is used to support the mold, and a water pool is provided below the mesh plate.

[0025] By adopting the above technical solution, in the case where the surface layer is a gel coat, the gel coat sprayed out of the mold can pass through the grid plate into the water pool, and the water in the water pool absorbs the gel coat, so the gel coat will not pollute the ground and does not need to be cleaned. The contaminated water is treated in an environmentally friendly manner after passing out of the water pool by the treatment equipment.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The shower room base improves the comfort of stepping by setting the surface layer; by setting the core board, its good thermal insulation performance reduces heat transfer, avoids the user's feet from being cold and uncomfortable in winter, and also reduces the heat loss in the shower room, which is more energy-saving; 2.

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] Embodiment 1

[0031] Reference Figure 1 and Figure 2 This embodiment discloses a shower room base, including a bottom plate 1, a core plate 2 fixed on the bottom plate 1, a surface layer 3 wrapped around the top surface of the core plate 2 and the outside of the side wall, and a drainage hole 4 is provided through the surface layer 3, the core plate 2, and the bottom plate 1.

[0032] The base plate 1 is a prefabricated plate, and the material of the base plate 1 is any one of cement board, ABS plastic board, SMC, and fiberboard.

[0033] The material of the core board 2 is an XPS board or an ABS plastic honeycomb board. The XPS board is an extruded polystyrene board, which has excellent and lasting thermal insulation, as well as superior water resistance and moisture resistance, and is corrosion-resistant and has a long service life. The XPS board is a type of foam board with higher hardness, is not easy to deform, and can provide a better support effect. At the same time, the XPS board has a certain elasticity, which can improve the comfort of the user standing. The ABS plastic honeycomb board has the advantages of light weight and high strength, and also has a good thermal insulation effect.

[0034] The material of the surface layer 3 is gel coat or ceramic plate or SMC, SMC is sheet molding compound. When the surface layer 3 is a ceramic plate or SMC, the surface of the surface layer 3 is preferably sprayed with imitation stone paint or gel coat, and the imitation stone paint and gel coat have a decorative and protective effect on the ceramic plate or SMC. When the surface layer 3 is a gel coat, the surface layer 3 is formed by spraying, and the surface layer 3 directly contacts the sole of the user's foot with a soft and skin-friendly surface, which improves comfort, and the surface layer 3 can provide a good waterproof effect.

[0035] Glass fibers 31 are embedded in the surface layer 3 and are located near the core board 2. The glass fibers 31 are hard needle-shaped materials and are used to increase the inner strength of the surface layer 3 and the firmness of the surface layer 3 after curing. The glass fibers 31 are partially embedded in the core board 2 and, combined with the adhesive effect of the glue, can increase the fixing strength between the surface layer 3 and the core board 2 to avoid separation or relative movement.

[0036] The top surface of the surface layer 3 is concave, and the lowest point of the concave is located at the drainage hole 4. The top surface shape of the core board 2 corresponds to the concave shape of the surface layer 3. The concave shape facilitates the water on the base to gather at the drainage hole 4, which is convenient for rapid drainage. The inner wall of the drainage hole 4 is provided with a waterproof layer, which can be formed by spraying a waterproof coating or by inserting a rubber sleeve or a silicone sleeve. The waterproof layer prevents the water in the drainage hole 4 from penetrating into the interior of the base or entering between the layers of the base product.

[0037] The implementation principle of a shower room base in the embodiment of the present application is as follows: by setting the surface layer 3, the comfort of stepping is improved; by setting the core board 2 of XPS board or ABS plastic honeycomb board material, its good thermal insulation performance reduces heat transfer, avoids the user's feet from being cold and uncomfortable in winter, and also reduces the heat loss in the shower room, which is more energy-efficient. The bottom plate 1 is the bottom material of the shower room base, which has high strength, can provide stable support, and is easy to install on the ground.

[0038] Embodiment 2

[0039] This embodiment discloses a processing technology for a shower room base, which is used to process the shower room base of the first embodiment, and includes the following steps: Step S1, making surface layer 3: Step S11: For the scenario where the surface layer 3 is a ceramic plate or SMC: the surface layer 3 is prefabricated with corresponding materials.

[0040] Reference Figure 3 and Figure 4 For the scenario where the surface layer 3 is a gel coat: use a mesh plate 51 to support the mold 5, and there is a water pool 52 below the mesh plate 51. Place the mold 5 with the opening facing upward, make the surface layer 3 on the mold 5, and cure for 8-12 minutes, preferably 10 minutes.

[0041] Reference Figure 4 The water pool 52 has a water inlet and a water outlet. The gel coat sprayed out of the mold 5 can pass through the mesh plate 51 into the water pool 52. The water in the water pool 52 absorbs the gel coat, so the gel coat will not pollute the ground and does not need to be cleaned. The polluted water is treated in an environmentally friendly manner after passing through the water pool 52.

[0042] The glass fibers 31 are sprinkled for reinforcement for 1.5-2.5 minutes, preferably 2 minutes, and the surface layer 3 is cured for 10-20 minutes, preferably 15 minutes.

[0043] The glass fibers 31 are evenly spread on the surface layer 3. Since the mold 5 is inverted, after the surface layer 3 is subsequently turned over, the glass fibers 31 are located away from the outer surface of the surface layer 3. Even if the surface layer 3 is worn after long-term use, the glass fibers 31 will not be exposed.

[0044] When the glass fibers 31 are sprinkled, the surface layer 3 is not completely solidified, so the glass fibers 31 are embedded in the surface layer 3 under the action of gravity, thereby improving the overall strength and tear resistance of the surface layer 3. After the surface layer 3 is completely solidified, part of the glass fibers 31 is exposed outside the surface layer 3.

[0045] Step S2, making the inner core board: Step S21: cutting and forming the core board 2 and prefabricating the bottom board 1.

[0046] The core board 2 is cut and shaped by hot cutting, that is, cutting by a heating knife or a heating wire. The physical cutting is combined with the melting effect of the core board 2 to make the cutting process more efficient, avoid burrs on the edge of the core board 2, and reduce the deformation of the core board 2 during the cutting process.

[0047] Step S22: The core board 2 and the bottom board 1 are compounded with glue for 2-4 minutes, preferably 3 minutes. The glue is AB glue, resin glue or foam glue. The core board 2 and the bottom board 1 are combined to form an inner core board, and pressed with a cold press for 0.5-1.5 hours, preferably 1 hour.

[0048] The core plate 2 and the bottom plate 1 are glued and fixed together by glue, and a cold press is used to preliminarily form an inward concave shape on the top surface of the core plate 2 , and the inward concave shape corresponds to the shape of the surface layer 3 .

[0049] Step S23: sending the composite inner core board into a hot press to press the arc for 0.5-1.5 hours, preferably 1 hour.

[0050] The heating surface of the hot press contacts the side of the core plate 2 away from the bottom plate 1, which is used to fit with the surface layer 3. The hot pressing action of the hot press facilitates the plastic deformation of the core plate 2, thereby forming a surface shape that fits the surface layer 3. The heating melts the core plate 2, greatly reducing the rebound deformation of the core plate 2 after the pressing is completed, making the size of the core plate 2 accurate.

[0051] Step S24: drilling a hole to form a drainage hole 4. The drilling is completed by using a drilling machine to drill through the core plate 2 and the bottom plate 1 at the same time.

[0052] Step S3, combining the surface layer 3 and the inner core board: Step S31: demoulding the surface layer 3 and cutting the edges; Reference Figure 5 A guide groove 21 for glue to enter is opened on the surface of the inner core board, and the inner core board is placed on the surface layer 3, and the two are compounded by glue dripping.

[0053] Since the glass fiber 31 partially protrudes from the bottom surface of the surface layer 3, the glass fiber 31 increases the coverage area of ​​the drip glue, improves the bonding strength between the surface layer 3 and the core board 2, and the glass fiber 31 can be embedded in the interior of the core board 2, further improving the fixing strength between the surface layer 3 and the core board 2 and avoiding relative slippage between the two.

[0054] On the one hand, the guide groove 21 facilitates the discharge of air between the inner core plate and the surface layer 3 to prevent bubbling. On the other hand, glue enters the guide groove 21 and forms reinforcing ribs after solidification to improve the structural strength.

[0055] Preferably, one end of the guide groove 21 is connected to the drainage hole 4, and the other end of the guide groove 21 is connected to the outer wall of the core plate 2, so that the guide groove 21 is radially distributed with the drainage hole 4 as the center, and both ends of the guide groove 21 can serve as ports for exhausting air.

[0056] Step S32: Use vacuum equipment 6 to press the inner core board and the surface layer 3 tightly for 2-4 minutes, preferably 3 minutes.

[0057] Reference Figure 6 A pressure film 61 is provided on the top of the vacuum equipment 6, and the pressure film 61 is an airtight sealed film. The vacuum equipment 6 uses a porous plate 62 to support the shower room base. The interior of the vacuum equipment 6 is connected to a vacuum pump 63. The shower room base is placed in the vacuum equipment with the surface layer 3 facing upward.

[0058] After starting the vacuum pump 63, the air in the space below the film 61 is evacuated. Under the action of the external atmospheric pressure, the force of the film 61 acts downward on the surface layer 3, further pressing the surface layer 3 and the core plate 2. The air between the surface layer 3 and the core plate 2 is discharged in combination with the vacuum suction. The guide groove 21 facilitates the discharge of air, further preventing bubbling and preventing bubbles from affecting the firmness of the bonding. The film 61 is used to press the surface layer 3. Due to its flexibility, the film 61 can avoid damage to the surface layer 3 on the one hand, and can reliably contact with the surface layer 3 on the other hand, and the surface contact area is large, so that the pressure is uniform.

[0059] Step S33: let it stand for 20-28 hours, preferably 24 hours, to complete the production of the shower room base.

[0060] In summary, the production and processing of the shower room base is completed through the above steps. The various layers of the shower room base are tightly combined, it is not easy to produce bubbles and gaps, the stability is good, and through hot pressing, the product has a higher shape stability.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
