Problems solved by technology

However, domestic plasticizers are mainly phthalic acid plasticizers such as DOP and DBP, and the research on non-toxic plasticizers such as citric acid esters and metabenzoic acid esters is still at the stage of concentrated sulfuric acid catalysis. Therefore, it is imminent to develop a new type of environmentally friendly plasticizer

Abstract

The invention discloses a compound ester plasticizer. The plasticizer is prepared from the following components in parts by weight: 30-40 parts of polyvinyl chloride resin, 10-12 parts of fatty acid methyl ester, 3-6 parts of pentaerythritol, 10-15 parts of acetalized polyvinyl alcohol, 7-9 parts of hydrogen peroxide, 3-6 parts of methacrylic acid and 2-5 parts of palm oil. The compound ester plasticizer has the advantages that chemical factors capable of polluting products can be eliminated, burden for sewage treatment can be greatly reduced, and production cost can be reduced. The preparation method has the advantages of no toxicity, environmental friendliness, safety, water saving, stability, short production cycle and low energy consumption.

Description

technical field [0001] The invention relates to a compound ester plasticizer. Background technique [0002] In recent years, various parts of my country have successively invested in the construction of large-tonnage ethylene projects. Therefore, the demand for plasticizers in the entire plastics processing industry is also increasing year by year. In addition, a certain number of plasticizer products are exported. Foreign research on plasticizers is now mainly focused on non-toxic plasticizers such as terephthalates, phosphates, epoxy esters, fatty acid esters, polyesters, and trimellitates. ; In the selection of catalysts, traditional concentrated sulfuric acid is also abandoned, and catalysts such as solid ion superacids, organic acids, and heteropolyacids, which have little corrosion to equipment and produce less pollution, are used. However, domestic plasticizers are mainly phthalic acid plasticizers such as DOP and DBP, and the research on non-toxic plasticizers such ...
