Plastic material capable of releasing anions and preparation method of plastic material

Abstract

The invention discloses a plastic material capable of releasing anions and a preparation method of the plastic material. The plastic material is prepared from the following raw materials in parts by weight: 80-100 parts of polyvinyl chloride resin, 1-10 parts of an anion additive, 20-30 parts of calcium carbonate powder, 5-15 parts of sepiolite powder, 1-2 parts of an ACR assistant, 2.5-4.2 titanium dioxide, 0.05-0.1 part of stearic acid, 3-4 parts of a lead-free calcium-zinc heat stabilizer, 0.3-0.4 part of polyethylene wax, 0.1-0.15 part of an ultraviolet light absorber and 0.01-0.03 part of ultramarine. The plastic material produced by the method has good heat dissipation performance and good tensile property; meanwhile, the molecular structures of the materials such as lead, cadmium and mercury are changed; the activity of harmful molecules is lowered; the content of partial harmful molecules in products is neutralized; and meanwhile, the plastic material also contains an anion releasing agent, so that the plastic material has antibacterial, anti-toxicity and smell-removing efficacies.

Description

technical field [0001] The invention relates to the technical field of environmental protection profiles, in particular to a plastic profile that can release negative ions and a preparation method thereof. Background technique [0002] Due to the huge market demand and broad development prospects, plastic profiles have developed rapidly in my country in recent years. Due to the fierce market competition, all plastic machinery manufacturers have to consider a problem, how to improve the quality of plastic profiles on the premise of ensuring product quality. Product productivity and qualification rate, to maximize the capacity of the equipment to reduce the production cost of the product; at the same time, plastic profile products are divided into window frames, stair handrails, wiring troughs, skirting boards, special-shaped pipes, etc. The raw material is mainly PVC. Most of the traditional plastic profile products use a low-grade lead-containing salt stabilizer raw material....

AI Technical Summary

Problems solved by technology

The raw material is mainly PVC. Most of the traditional plastic profile products use a low-grade lead-containing salt stabilizer raw material. The harmful substances such as lead, mercury, chromium, and polybrominated biphenyls seriously exceed the standard, which does not meet environmental protection requirements.
