Problems solved by technology

Such plasticizers in my country mainly include dioctyl phthalate (DOP), dibutyl phthalate (DBP), diheptyl phthalate (DBP), di Isodecyl ester (DIDP) and diisooctyl phthalate (DIOP), these plasticizers generally have the disadvantages of high cost and environmental protection, and at the same time pose a serious threat to human health, so the EU since 2007 In January, the use of DBP dibutyl phthalate and DOP dioctyl phthalate plasticizers in children's toys and supplies was banned, and the use of DINP, DIDP, and DNOP was restricted

Abstract

The invention discloses an ester plasticizer for PVC. The plasticizer mainly consists of the following raw materials, by weight: 10-30 parts of diethylene glycol dibenzoate, 10-30 parts of a polyhedral organosilicon hybrid star polymer, 10-20 parts of polyvinyl chloride, 5-10 parts of activated carbon, 3-5 parts of glycerol, 5-8 parts of soda ash, 1-5 parts of octyl ethylene oxide, 3-5 parts of carbamide, and 1-3 parts of epoxy soybean oil. The ester plasticizer for PVC of the invention has characteristics of non-toxicity and environmental protection, can meet the application requirements, isshort in production cycle, has application properties of migration resistance, solvent effect resistance, weather resistance and the like, is easy in production process, and is beneficial to market-oriented production applications.

Description

technical field [0001] The invention relates to the technical field of polymer material additives, in particular to a PVC lipid plasticizer. Background technique [0002] Plasticizers refer to organic substances that increase the plasticity of plastics, improve the fluidity of resins during plastic processing, and make plastic products flexible. Plasticizers are usually viscous liquids with high boiling points, difficult to volatilize or solids with low melting points. Plasticizers are generally required to be colorless, non-toxic, odorless, cold-resistant, heat-resistant, volatile and mobile, and chemically Good stability, cheap and easy to get. Plasticizers can weaken the van der Waals force between plastic polymer molecules, increase the mobility of polymer molecular chains, reduce the crystallinity of polymer molecular chains, and enhance the plasticity of polymers, thereby reducing the hardness and softening temperature of polymers. As well as the embrittlement temper...
