Abstract

The invention discloses a soft PVC (Poly Vinyl Chloride) plasticizer prepared from the following components in parts by weight: 10-20 parts of fatty acid methyl ester, 20-30 parts of epoxy fatty acid methyl ester, 5-8 parts of benzoic acid, 5-10 parts of ethylene glycol, 3-5 parts of carbonyl diamine, 5-8 parts of soluble polyvinyl alcohol and 2-6 parts of epoxy soybean oil. The soft PVC plasticizer disclosed by the invention has the advantages of no toxicity, environment friendliness, good compatibility with PVC resin, high plasticizing efficiency and favorable durability.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a soft PVC plasticizer. Background technique [0002] Studies have confirmed that DOP can enter the human body through various channels such as respiratory tract, mouth, skin absorption, and intravenous infusion. It has a great toxic effect on the body. DOP in PVC products in medical devices is released into the body of patients, which will cause greater harm to patients. In 2005, the European Union issued a warning: the baby bottle teat originating in China contains DOP, which does not meet the relevant hygienic standards and is prohibited from sale. Another example, in October 2005, the AQSIQ organized spot checks on 44 kinds of PVC food wraps. Among them, 12 kinds of PVC cling film contain adipate, and the relevant departments have ordered the relevant enterprises to stop selling them out of the factory. Plasticizer is one of the essential additives in soft PVC p...
