Embodiment Construction

[0016] The present invention will be further described below in conjunction with embodiment.

[0017] The environmentally friendly straw PVC composite board is a multi-layer composite structure, including a wear-resistant layer from top to bottom, a color film layer, a negative film, and a base material; straw, glass fiber cloth, and SiC nano powder are added to the base material.

[0018] The wear layer is a transparent film with a UV coating layer.

[0019] The preparation process of the above-mentioned environment-friendly straw PVC composite board: adopt a group of synergistic low-molecular-weight repellents and combine them with specially modified equipment to make the blended composite materials remove the contained organic volatiles in a molten state.

Abstract

The invention discloses an environment-friendly straw PVC compound plate which has a multilayer compound structure and comprises a wearing layer, a colorful film, a base plate and a substrate from topto bottom; straws are added into the substrate; the further improvement is as follows: a glass fabric is added into the substrate; SiC nanometer powder is added into the substrate; a transparent filmwith a UV coating layer serves as the wearing layer. According to the preparation technology of the environment-friendly straw PVC compound plate, a set of synergistic low-molecule repellents are combined with the device subjected to special structure improvement, so that the organic volatile components contained in the blended compound material can be removed under a molten state. The environment-friendly straw PVC compound plate has low smoke density, high strength and high toughness and is capable of realizing the large-scale utilization of crop straws.

Description

technical field [0001] The invention relates to a polymer composite material, in particular to a straw PVC composite board. Background technique [0002] Natural fiber / PVC composite material is a new type of green and environmentally friendly composite material, which is of great significance to the large-scale utilization of crop straw and the reduction of environmental pollution. Foreign research in this area was earlier, and the products have been widely used, while domestic research started late, and there is a big gap between the technical level of natural fiber / PVC composite materials in my country and the international advanced level, especially The preparation technology of straw / PVC composite material is still immature, and the large-scale utilization of crop straw has not been realized, and the pollution of straw to the environment has not been fundamentally solved. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention prop...
