Description

Technical Field

[0001] The invention relates to a PVC gusset plate, in particular to a PVC gusset plate with high impact resistance. Background Art

[0002] PVC gussets are made of polyvinyl chloride resin as the base material, with additives such as anti-aging agents and modifiers added, and are made through processes such as mixing, calendering, and vacuum forming. The material is light in weight, easy to install, waterproof and moisture-proof, and moth-proof. The surface has various patterns and patterns, and has good properties such as pollution resistance, flame retardancy, sound insulation, and heat insulation. PVC gussets are divided into PVC gussets for wall decoration and PVC gussets for ceilings according to the usage scenarios. Most of the PVC gussets for wall decoration are long rectangular plates. The interior of the PVC gusset is generally formed with several through cavities, which can not only reduce the quality of the gusset, save production costs, but also maintain sufficient main body strength. However, when a sharp object hits the PVC gusset, if the collision site happens to be the cavity area, the thickness of this part of the plate is thin and the strength is relatively low, so it is easy to be damaged. Especially for PVC gussets for wall decoration, it is easy to have accidental bumps in life. At the same time, PVC gussets for wall decoration are often fixed on the wall by means of gluing, nailing, etc. It is quite troublesome to replace damaged gussets. Therefore, it is urgent to develop a PVC gusset with high impact strength to solve the existing problems. Summary of the invention

[0003] The invention provides a PVC gusset plate with high impact strength, which solves the problem in the prior art that the gusset plate is easily damaged by being bumped.

[0004] The above technical problems of the present invention are mainly solved by the following technical solutions: a high impact strength PVC gusset plate, especially a PVC gusset plate for wall decoration, comprises a base plate and a panel, the main body contour of the base plate is a long rectangular strip, and a plurality of spaced-apart female clamping bodies and a plurality of first support ribs distributed at equal heights are arranged on its upper surface, the female clamping bodies and the first support ribs are both strip structures arranged along the length direction of the base plate, and a first overlapping bottom sheet and a first overlapping cover sheet are respectively arranged on both sides of the base plate in the length direction, the upper surface of the first overlapping bottom sheet is flush with the lower surface of the first overlapping cover sheet, and the first overlapping bottom sheet is flush with the lower surface of the first overlapping cover sheet. A first card slot is provided on the upper surface of a lap bottom film, and a first card rib adapted to the shape of the first card slot is provided on the lower surface of the first lap cover film; the main contour of the panel is consistent with the main contour of the base plate, and a plurality of spaced-apart sub-card connecting bodies are provided on the bottom surface of the panel, and the sub-card connecting bodies are strip structures arranged along the length direction of the panel, and the surface of the remaining area is covered with a glass fiber reinforcement layer; the sub-card connecting body can be clamped and fixed with the mother card connecting body, and the first supporting rib is abutted against the glass fiber reinforcement layer, and the clamping structure of the sub-card connecting body and the mother card connecting body can be any existing conventional clamping structure.

[0005] When the sheet is impacted, the damaged parts are the parts with the largest bending and twisting deformation. The larger the bending and twisting deformation, the greater the tensile stress of the sheet. When the tensile stress is greater than the cracking strength of the material, the material will break. Because the thickness of the sheet will cause the stretching amplitudes on both sides of the sheet to be inconsistent when the sheet is bent and twisted, the larger the bending and twisting radius, the greater the stretching amplitude. This also leads to the first cracking part of the gusset plate when it is impacted is the other side surface of the impact part. Corresponding to the present invention, when the panel is engaged with the bottom plate, the sub-clip body and the mother-clip body are engaged, and the first support rib abuts against the bottom of the panel. Therefore, the area on the panel supported by the first support rib and the sub-clip body has a high impact strength, while the bottom of other areas is hollow. Once this part of the panel collides with an external object, the first crack must be on the bottom surface of the collision part, so the bending deformation of this part is the largest. Therefore, the present invention enhances the performance of the panel to resist impact by arranging a glass fiber reinforcement layer in the hollow part of the bottom surface of the panel to enhance the tensile strength of this part. The biggest feature of glass fiber is its high tensile strength. The tensile strength is 6.3-6.9 g / d under standard conditions, which is much greater than that of PVC materials. The glass fiber in the present invention can be fixed on the surface of the panel by coatings such as resins.

[0006] At the same time, the panel and the base plate in the present invention are detachable structures. Therefore, during the installation process, the base plate is generally fixed on the wall as needed, and then the panel is clamped and fixed with the corresponding base plate. The adjacent base plates are positioned by the first overlapping bottom plate and the first overlapping cover plate covering each other, and the first clamping groove and the first clamping rib are clamped and positioned with each other. The advantage of such installation is that when nailing is used for fixing, the nails will be covered by the panel, so the installation is more beautiful. At the same time, once the panel is damaged, scratched or otherwise damaged in any way that affects the appearance, the panel can be easily replaced.

[0007] Furthermore, a second overlapping bottom sheet and a second overlapping cover sheet are respectively provided on both sides of the panel in the length direction, the upper surface of the second overlapping bottom sheet is flush with the lower surface of the second overlapping cover sheet, a second card slot is provided on the upper surface of the second overlapping bottom sheet, and a second card rib adapted to the shape of the second card slot is provided on the lower surface of the second overlapping cover sheet, and when the bottom plate and the panel are covered and fixed to each other, the first overlapping bottom sheet and the second overlapping bottom sheet are distributed on the same side;

[0008] The upper surface of the first overlapping bottom sheet is provided with a second supporting rib protruding upwards. When the bottom plate and the top plate are overlapped and fixed to each other, a gap for accommodating the second overlapping bottom sheet is formed between the second supporting rib and the second overlapping cover sheet.

[0009] Through the above technical scheme, when the two pieces of the present invention are buckled together, the first overlapping bottom piece and the first overlapping cover piece cover and dock with each other, the first card slot and the first card rib are engaged with each other for positioning, the second overlapping bottom piece and the second overlapping cover piece cover and dock with each other, the second card slot and the second card rib are engaged with each other for positioning, and the second supporting rib is between the second overlapping bottom piece and the first overlapping cover piece, so that the overlapping part not only has good flatness, but also has high impact resistance.

[0010] The present invention also provides a production process for PVC gusset plate, characterized in that: the PVC gusset plate is the above-mentioned high impact strength PVC gusset plate, step 1, respectively putting the prepared raw material particles into an extruder equipped with a bottom plate extrusion die and an extruder equipped with a panel extrusion die to obtain a bottom plate extrusion melt and a panel extrusion melt;

[0011] Step 2, cooling and solidifying the bottom plate extrusion melt and the panel extrusion melt to obtain a bottom plate extrusion body and a panel extrusion body;

[0012] Step 3: coating the bottom surface of the panel extrusion with a glass fiber reinforcement layer, and drying and curing the layer;

[0013] Step 4: Perform a printing process on the top surface of the panel extrusion body;

[0014] Step five: cutting the bottom plate extrusion body and the panel extrusion body into sections.

[0015] Furthermore, in step 3, the glass fiber reinforcement layer can be coated on the panel by roller coating or spraying, and the coating can be acrylic, polyurethane, epoxy resin, etc. The coated glass fiber is dried or light-cured, and the coating is completely cured.

[0016] Therefore, compared with the prior art, the present invention has the following characteristics: 1. Therefore, the present invention enhances the tensile strength of the hollow part of the bottom surface of the panel by arranging a glass fiber reinforcement layer in the hollow part of the bottom surface of the panel to enhance the impact resistance of the panel; 2. At the same time, the panel and the base plate in the present invention are detachable structures. When fixed by nailing, the nails will be covered by the panel, so the installation is more beautiful. At the same time, once the panel is damaged, scratched or otherwise damaged in any way that affects the appearance, the panel can be easily replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0024] Example 1: See Figure 1 , Figure 2 and Figure 3A high impact strength PVC gusset plate, in particular a PVC gusset plate for wall decoration, comprises a base plate 100 and a panel 200. The main body of the base plate is a long rectangular shape with a length and width of 300*30 cm. The upper surface of the base plate is provided with five equally spaced female clamping bodies 110 and 16 to 24 equally spaced first support ribs 120. The first support ribs are distributed at approximately the same spacing. The female clamping bodies and the first support ribs are both strip structures arranged along the length direction of the base plate. The two sides of the base plate in the length direction are respectively provided with a first overlapping bottom sheet 130 and a first overlapping cover sheet 140. The upper surface of the first overlapping bottom sheet is connected to the first overlapping cover sheet. The lower surface of the sheet is flush, a first card slot 131 is provided on the upper surface of the first overlapping bottom sheet, and a first card rib 141 adapted to the shape of the first card slot is provided on the lower surface of the first overlapping cover sheet; the main contour of the panel is consistent with the main contour of the base plate, and five spaced-apart sub-card bodies 210 are provided on the bottom surface of the panel. The sub-card bodies are strip structures arranged along the length direction of the panel, and the surface of the remaining area is covered with a glass fiber reinforcement layer 220; the sub-card bodies can be clamped and fixed with the mother card body, and the first supporting rib is abutted against the glass fiber reinforcement layer, and the clamping structure of the sub-card body and the mother card body can be any existing conventional clamping structure.

[0025] When the sheet is impacted, the damaged parts are the parts with the largest bending and twisting deformation. The larger the bending and twisting deformation, the greater the tensile stress of the sheet. When the tensile stress is greater than the cracking strength of the material, the material will break. Because the thickness of the sheet will cause the stretching amplitudes on both sides of the sheet to be inconsistent when the sheet is bent and twisted, the larger the bending and twisting radius, the greater the stretching amplitude. This also leads to the first cracking part of the gusset plate when it is impacted is the other side of the impact part. Corresponding to this embodiment, when the panel is engaged with the bottom plate, the sub-clamp body and the mother clamp body are engaged, and the first support rib abuts against the bottom of the panel. Therefore, the area on the panel supported by the first support rib and the sub-clamp body has a high impact strength, while the bottom of other areas is hollow. Once this part of the panel collides with an external object, the first crack must be on the bottom surface of the collision part, so the bending deformation of this part is the largest. Therefore, this embodiment enhances the panel's resistance to impact by setting a glass fiber reinforcement layer in the hollow part of the bottom surface of the panel to enhance the tensile strength of this part. The biggest feature of glass fiber is its high tensile strength. The tensile strength is 6.3-6.9 g / d under standard conditions, which is much greater than that of PVC materials. The glass fiber in this embodiment is mixed with a resin coating and then coated on the panel surface.

[0026] At the same time, the panel and the base plate in this embodiment are detachable structures. Therefore, during the installation process, the base plate is generally fixed on the wall as needed, and then the panel is clamped and fixed with the corresponding base plate. The adjacent base plates are positioned by the first overlapping bottom plate and the first overlapping cover plate covering each other, and the first clamping groove and the first clamping rib are clamped and positioned with each other. The advantage of such installation is that when nailing is used for fixing, the nails will be covered by the panel, so the installation is more beautiful. At the same time, once the panel is damaged, scratched or otherwise damaged in any way that affects the appearance, the panel can be easily replaced.

[0027] See Figure 1 and Figure 4 , a second overlapping bottom sheet 230 and a second overlapping cover sheet 240 are respectively provided on both sides of the panel in the length direction, the upper surface of the second overlapping bottom sheet is flush with the lower surface of the second overlapping cover sheet, a second card slot 231 is provided on the upper surface of the second overlapping bottom sheet, and a second card rib 241 adapted to the shape of the second card slot is provided on the lower surface of the second overlapping cover sheet, when the bottom plate and the panel are covered and fixed to each other, the first overlapping bottom sheet and the second overlapping bottom sheet are distributed on the same side;

[0028] See Figure 1 and Figure 4 The upper surface of the first overlapping bottom sheet is provided with a second supporting rib 150 protruding upward. When the bottom plate and the panel are overlapped and fixed to each other, a gap for accommodating the second overlapping bottom sheet is formed between the second supporting rib and the second overlapping cover sheet.

[0029] Through the above technical scheme, when the two pieces of the present embodiment are buckled together, the first overlapping bottom piece and the first overlapping cover piece cover and dock with each other, the first card slot and the first card rib are engaged with each other for positioning, the second overlapping bottom piece and the second overlapping cover piece cover and dock with each other, the second card slot and the second card rib are engaged with each other for positioning, and the second supporting rib is between the second overlapping bottom piece and the first overlapping cover piece, so that the overlapping part not only has good flatness, but also has high impact resistance.

[0030] See Figure 1 and Figure 4 The sub-card body is composed of a connecting body 211 and an expanded body 212. The connecting body is used to connect the expanded body and the panel. The width of the expanded body is larger than the connecting body. A downwardly recessed plug-in groove 111 is formed on the upper surface of the mother card body, and the contour of the plug-in groove is adapted to the contour of the sub-card body.

[0031] See Figure 1 The bottom surface of the bottom plate is provided with three to five raised strips 160 distributed along its length direction, and are distributed at equal intervals. The area between the raised strips is relatively concave, so a certain cavity can be formed between the raised strips and the wall surface, which can be used to fill the adhesive material, such as foam glue.

[0032] Example 2: See Figure 5The difference between this embodiment and the first embodiment is that the sub-clamp body is composed of an upper connecting piece 213 and an upper hook 214, and the mother clamp body is composed of a lower connecting piece 112 and a lower hook 113. The upper hook and the corresponding lower hook are in opposite directions and can be hooked up and down with each other, and the directions of adjacent upper hooks are set in opposite directions. After the sub-clamp body and the mother clamp body in this embodiment are engaged, only a vertical tension limit can be generated.

[0033] The present invention can be modified in various ways which are obvious to those skilled in the art, and such modifications are not considered to depart from the scope of the present invention. All such modifications which are obvious to those skilled in the art are intended to be included within the scope of the present claims.
