Abstract

The invention discloses a polyvinyl chloride (PVC) injection molding pipe material. The material is prepared from the following ingredients in parts by weight: 30-70 parts of PVC resin, 10-15 parts of active light calcium carbonate, 4-5 parts of polyvinyl butyral, 2-4 parts of triphosphate, 0.4-0.6 part of hydroquinone, 5-12 parts of stearic acid, 3-5 parts of triphenyl phosphate, 1-5 parts of cyclohexanone, 5-10 parts of industrial paraffin and 10-20 parts of wood fiber. According to the material, the traditional plastic-based injection molding materials are replaced with a novel woody injection molding material, which is recyclable and environment-friendly and is free from any injury to human bodies, and the raw materials, which can be tree wood, tree leaves, wood sawdust, leftover materials of industrial sheets and the like, are cheap and are easily obtained, so that the consumption of plastics can be greatly reduced, and the unity of injection molding materials is changed; meanwhile, products are strong in stability, are free from contraction distortion and can be repeatedly recycled.

Description

Technical field [0001] The invention relates to a polyvinyl chloride injection molding pipe. Background technique [0002] At present, many injection molding products on the market are mainly formed of injection molding materials such as styrene, polycarbonate and polystyrene. These materials contain many harmful chemical components on the one hand, which can cause harm to human health. On the other hand, the cost is high and cannot Recycling, and it is difficult to degrade after being discarded, which will cause serious environmental pollution. Summary of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a polychloride which has the characteristics of environmental protection, no harm to the human body, recyclability, etc., and is low in cost, thereby overcoming the deficiencies in the prior art. Ethylene injection pipe. [0004] In order to solve the above-mentioned technical problem...
