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.

Abstract

The invention discloses a formula and a preparation method of novel environment-friendly sectional materials. The formula consists of the following raw materials in parts by weight: 65-85 parts of polyvinyl chloride resin, 70-80 parts of polyvinyl chloride reclaimed materials, 20-30 parts of calcium carbonate powder, 5-15 parts of chlorinated polyethylene, 1-2 parts of ACR auxiliaries, 2.5-4.2 parts of titanium white, 0.05-0.1 part of stearic acid, 3-4 parts of lead-free calcium-zinc thermal stabilizer, 0.3-0.4 part of polyethylene wax, 0.1-0.15 part of ultraviolet absorbent and 0.01-0.03 part of ultramarine. Plastic sectional materials prepared by the preparation method have good heat dissipating performance and good tensile property; meanwhile, molecular structures of materials containing lead, cadmium, mercury and the like are changed, the activity of harmful molecules is lowered, and the content of part of harmful molecules in products is neutralized, so that the products reach ROHS and related IEE standards of European Union.

Description

technical field [0001] The invention relates to the technical field of environment-friendly profiles, in particular to a novel formula of environment-friendly profiles 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. The...
