PVC wood-plastic decoration material with high impact resistance

Abstract

The invention discloses a PVC wood-plastic decoration material with high impact resistance. The PVC wood-plastic decoration material is prepared from the following raw materials by weight: 100 to 105 parts of polyvinyl chloride, 15 to 18 parts of kaolin, 30 to 35 parts of wood powder, 5 to 7 parts of carbonyl iron powder, 0.8 to 1.2 parts of copper sulphate pentahydrate, 4 to 6 parts of butadiene-acrylonitrile rubber, 0.2 to 0.4 part of a titanate coupling agent NDZ201, 0.4 to 0.6 part of a silane coupling agent YH62, 3 to 4 parts of epoxy flax seed oil, 4 to 5 parts of PE wax, 4 to 5 parts of alumina silicate and 8 to 9 parts of cocoanut shell fiber. The wood-plastic decoration material prepared in the invention has the advantages of good performance, water resistance, moisture resistance, high environmental protection performance, no pollution, recyclability, good fire resistance, no combustion, no deformation, wide sources of the raw materials and conservation of resources, and is worth popularization.

Description

technical field [0001] The invention relates to the technical field of wood-plastic composite materials, in particular to a high-impact-resistant PVC wood-plastic decorative material. Background technique [0002] As early as the 1940s, it was discovered that nitrile rubber and PVC were used together for research. Nitrile rubber has a certain polarity, and the solubility parameters of PVC are very close. They are both amorphous polymers. Good compatibility, so they are usually blended, and the alloy material obtained has excellent weather resistance, solvent resistance, good mechanical strength and processing performance, and is widely used in seals, wire and cable sheathing, Oil pipeline and other fields. The alloy materials of nitrile rubber and polyvinyl chloride are divided into cross-linked type and non-cross-linked type. The cross-linked alloy is insoluble and infusible, which is difficult to recycle and causes serious pollution to the environment. Although the non-cr...

Problems solved by technology

On the one hand, kaolin has a large output and low price, and its compounding with polymer matrix can greatly reduce the cost of plastics. On the other hand, the addition of kaolin can improve the thermal stability, hardness, rigidity and endow the material with certain properties. However, the raw ore kaolin directly mined at present has small particle size, high surface energy, and is easy to agglomerate. The surface contains hydrophilic hydroxyl groups and oxygen-containing groups, which are very different from the interface of polymer materials. dispersion
