PVC foamed fold-resistant board and preparation method thereof

Abstract

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. The PVC foam fold-resistant board includes a core layer and a skin layer. The core layer is made of foamed polyvinyl chloride material. The raw materials are PVC resin powder Ⅰ, filler Ⅰ, foam regulator, composite foaming agent, calcium zinc stabilizer, large Composed of soybean oil, lubricant and pigment; the upper skin layer and the lower skin layer have the same raw materials, and the skin layer material is composed of PVC resin powder Ⅰ, PVC resin powder Ⅱ, filler Ⅱ, processing aids, special agent for folding and toughening, and weather resistance modifier , Calcium zinc stabilizer, lubricant and pigment; special agent for folding and toughening is high molecular weight acrylate chlorinated polyethylene graft polymer. The PVC foam folding board has high strength, tensile resistance and folding resistance, the skin does not break, can be bent at a large angle, has no creases, reduces the combined interface and joint surface of the composition, is more environmentally friendly and hygienic, easy to clean, and cost-effective , The advantages of a wide range of use.

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. 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 decoration materials, etc. Furniture includes various cabinets and room partitions , office partitions, screens, etc., in terms of transportation decoration, it is mainly used for the bottom plates of large and medium-sized passenger cars, trains and ships.

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.
