Abstract

The invention discloses a migration-resistant environment-friendly plasticizer with a micro-crosslinking structure and a preparation method of same. The raw material formula mainly comprises the following components in parts by weight: 10-70 parts of epoxidized fatty acid ester, 5-40 parts of a polyester plasticizer, 3-5 parts of vinyl chloride-vinyl acetate, 1-3 parts of cellulose acetate butyrate, 3-5 parts of chlorinated paraffin, 0.1-2 parts of an antioxidant, 2-6 parts of polyether polyol, 3-10 parts of a polyurethane curing agent and 5-60 parts of chlorinated fatty acid methyl ester. By constructing a micro-crosslinking structure, the compatibility of epoxidized fatty acid ester and PVC resin is fully utilized, and an interpenetrating network structure can be formed after reactive hydrogen contained in the epoxidized fatty acid ester reacts with isocyanate. The micro-crosslinking structure has a more obvious effect on preventing the plasticizer from being separated out and is higher in heat-resistant stability, so that the problems that the plasticizer is prone to migration, poor in heat-resistant stability, short in service life, not environmentally friendly and the like are solved.

Description

technical field [0001] The invention relates to a plasticizer, in particular to a migration-resistant micro-crosslinked structure environment-friendly plasticizer and a preparation method thereof. The plasticizer is mainly used in the preparation of polyvinyl chloride film. Background technique [0002] The main component of polyvinyl chloride film is polyvinyl chloride, which is widely used in packaging and other fields. PVC film needs to add other components to enhance its performance, such as mechanical properties, heat resistance, toughness, and ductility. Wait. Plasticizer is a polymer material additive widely used in industrial production, also known as plasticizer. The use of plasticizers can improve the performance of polymer materials, reduce production costs, and increase production efficiency. It is an important class of chemical product additives, and its content can sometimes reach 50% of the product. Plasticizer molecules can be inserted between polymer mole...
