Abstract

The invention discloses an environment-friendly polyvinyl chloride plasticizer which is prepared from the following components in parts by weight: 20-30 parts of metal salt of terephthalic acid, 10-20 parts of polyethyleneglycol, 5-12 parts of trimethylene ether, 6-15 parts of oxydol, 3-6 parts of tritolyl phosphate and 5-8 parts of activated carbon. The plasticizer eliminates the chemical factors which possibly pollute the product, reduces abundant sewage treatment load, and lowers the production cost. The preparation method has the advantages of no toxicity, environment friendliness, high safety, water saving, high stability, short production cycle and low energy consumption.

Description

technical field [0001] The invention relates to a plasticizer added when producing PVC products, in particular to an environment-friendly polyvinyl chloride plasticizer. Background technique [0002] Polyvinyl chloride (PVC) is a general-purpose plastic with excellent comprehensive properties, and plasticizers are the most widely used additives in PVC products, making important contributions to the large-scale industrial application of PVC. Phthalate plasticizers are the family with the largest amount, the largest variety and the widest application in the field of plasticizers. In recent years, there have been reports abroad that plasticizers such as octyl phthalate (DOP) may cause cancer, and their use is limited. Environmentally friendly and low-toxic green plasticizers such as citrate, trimellitate, diethylene glycol dibenzoate and polyester are favored by people and have broad application prospects. Triacetin is safe and non-toxic, and has been used as a plasticizer fo...
