PVC foamed fold-proof plate and preparation method thereof

Abstract

The invention belongs to the technical field of polyvinyl chloride plates, and particularly relates to a PVC foamed fold-proof plate and a preparation method thereof. The PVC foamed fold-proof plate comprises a core layer and surface layers, wherein the core layer is made from a foamed PVC material, and is prepared from PVC resin powder I, filler I, foaming regulator, compound foaming agent, calcium-zinc stabilizer, soybean oil, a lubricating agent and pigment; the upper surface layer and the lower surface layer are made of same raw materials; the surface layer is prepared from PVC resin powder I, PVC resin powder II, filler II, a processing aid, a fold-proof toughening specific agent, a weather-resistant modifying agent, calium-zinc stabilizer, a lubricating agent and pigment; and the fold-proof toughening specific agent is high-molecular-weight chlorinated polyethylene acrylate grafted polymer. The PVC foamed fold-proof plate has the advantages of high strength, pulling and folding resistance, surface cracking prevention, large-angle fold use availability and no mark, few combined joint and joint surface of the composition, environmental friendliness, sanitation, convenience in cleaning, high cost performance and wide application range.

Description

technical field [0001] The invention belongs to the technical field of polyvinyl chloride boards, and in particular relates to a PVC foamed fold-resistant board and a preparation method thereof. Background technique [0002] At present, the application fields of PVC foam products are mainly advertising industry, indoor and outdoor construction and decoration materials, furniture, flooring and vehicle and ship decoration.

AI Technical Summary

Problems solved by technology

Advertisement decoration is mainly used for advertising display boards, mounting boards, silk screen, inkjet painting, engraving, etc. Doors and windows and decorative building materials include PVC foamed doors and windows, pipes, wall panels and other decorative materials, etc. Furniture includes various cabinets and room partitions , office partitions, screens, etc. The vehicle decoration is mainly used for the bottom plates of large and medium-sized passenger cars, trains and ships. Traditional production usually uses wood and plywood and other materials; these two materials are often deformed due to moisture. When it needs to be bent, it must be cut and reassembled. It cannot be bent directly, which increases the joint surface gap and seriously affects the use effect. At the same time, it wastes forest resources and is not conducive to environmental protection.

[0003] Polyvinyl chloride foam board is an emerging material. Although it has solved the problem of moisture deformation and has a certain degree of folding resistance, it will still break when it is folded at a large angle, and it still needs to be glued and nailed for secondary tightening. Solid, for example, the polyvinyl chloride foamed cabinet board in the prior art is often because it is not resistant to folding, it is easy to be cracked and deformed during use, and it cannot be directly bent, which seriously affects its popularization and use.
