Abstract

The invention discloses an environment-friendly PVC specific toughening enhancer which comprises the following components in parts by weight: 25-55 parts of linear polyethylene, 20-35 parts of polypropylene, 5-15 parts of butadiene, 4-11 parts of ABS, 4-8 parts of trimethylolpropane, 6-10 parts of acrylate, 5-23 parts of zinc lanolate, 5-13 parts of calcium acetylacetonate, 2-8 parts of antioxidant, 5-18 parts of high glue powder and 3-5 parts of EB. The invention also discloses a preparation method of the product. According to the environment-friendly PVC special toughening enhancer, linear polyethylene, polypropylene, butadiene, ABS and high rubber powder are selected as main toughening enhancer raw materials and used as toughening enhancers in PVC extrusion and injection molding processing industries, and the comprehensive performance is good; in the processing process of PVC, the PVC toughening enhancer is matched with other stabilizers for use, pollution discoloration reaction isavoided, vulcanization pollution is avoided, and environmental friendliness and non-toxicity are achieved.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to an environmentally friendly PVC special-effect toughening enhancer and a preparation method thereof. Background technique [0002] Chlorinated polyethylene (CPE) is a saturated polymer material. It is made of polyethylene (PE) after chlorination modification. The appearance is white powder, non-toxic and tasteless. , still has good flexibility, has good compatibility with other polymer materials, and has a high decomposition temperature. However, chlorinated polyethylene (CPE) only plays a toughening role in the processing of polyvinyl chloride (PVC) plastics, and has no strengthening effect, making plastic products soft and not hard enough. [0003] Therefore, the development of an environmentally friendly PVC special-effect toughening enhancer will have broad development prospects. Contents of the invention [0004] The technical problem to be solved by the present inventi...
