Ester plasticizer

Abstract

The invention discloses an ester plasticizer which consists of the following raw materials in parts by mass: 15-20 parts of epoxidized fatty acid methyl ester, 10-15 parts of p-hydroxybenzoic acid, 10-15 parts of DOP, 10-12 parts of dioctyl sebacate, 8-10 parts of trioctyl trimellitate, 10-15 parts of dioctylterephthalate, 8-10 parts of ethyl benzoate, 10-12 parts of methyl parahydroxybenzoats, 5-10 parts of white carbon black, 5-8 parts of nano carbon fibers, 6-8 parts of diethylene glycol, 7-9 parts of 2-propanol, 8-12 parts of hydrogen peroxide, 8-10 parts of petroleum resin and 6-10 parts of glycerinum. The ester plasticizer is low in cost, non-toxic, harmless, high in performance, high in plasticization efficiency, cold-resistant, heat-resistant, fouling resistant, anti-extraction, high in mobility, high in electric insulation property and stable to light and heat.

Description

technical field [0001] The invention relates to the technical field of plasticizers, in particular to an ester plasticizer. Background technique [0002] Plastic is one of the most widely used supplies, and it is now used in large quantities, and the most consumed are polyvinyl chloride, polyethylene and polypropylene. There are many forms of polyvinyl chloride products, which can be divided into three categories: hard polyvinyl chloride, soft polyvinyl chloride, and polyvinyl chloride paste. Rigid PVC is mainly used for extruded products such as pipes, door and window profiles, sheets, etc., as well as injection molded parts such as joints and electrical parts, and extrusion blown bottle products. They account for more than 65% of the consumption of polyvinyl chloride. Soft polyvinyl chloride is mainly used in calendered sheets, automotive interior accessories, handbags, films, wires and cables, and medical products.

Problems solved by technology

People have higher and higher environmental protection requirements for plastic materials, but the general material structure itself is not easy to modify, and after various processing, the product will have defects such as brittleness, poor heat resistance, and insufficient viscosity, so the application of the material is limited.
