Environment-friendly stabilizer

Abstract

The invention relates to an environment-friendly stabilizer which is applied to the machining process of PVC resin. The environment-friendly stabilizer is prepared from calcium stearate, zinc stearate, di-n-butyltin dilaurate, epoxidized soybean oil and pentaerythritol in parts by weight. The various components of the stabilizer of the invention can be fully mixed in the production process of the stabilizer, thereby greatly improving the uniformity of mixed dispersion with resin. The stabilizer of the invention has the advantages of excellent heat stability, prolonged stable phase, excellent electrical insulation property, good weather resistance, low price, good transparency, no toxicity and improved lubricating property.

Description

technical field [0001] The invention relates to a stabilizer, in particular to an environment-friendly stabilizer used in the processing of PVC resin. Background technique [0002] PVC resin is a polar non-crystalline high polymer with strong force between molecules, and it is a hard and brittle material. PVC resin (PVC) is one of the important organic synthetic materials. English name: Polyvinyl Chloride, chemical structural formula: (CH2-CHCL)n, its products have good physical and chemical properties, and are widely used in industry, construction, agriculture, daily life, packaging, electric power, public utilities and other fields. PVC resin can be processed into various plastic products, which can be divided into soft products and hard products according to their uses. They are mainly used to produce transparent sheets, pipe fittings, gold cards, blood transfusion equipment, soft and hard pipes, plates, doors and windows. , Profiles, films, electrical insulation materi...
