Description

technical field [0001] The invention relates to a compound synthesis device, in particular to a production device of ethylene-vinyl acetate-acrylic acid graft copolymer. Background technique [0002] The ethylene-vinyl acetate-acrylic acid graft copolymer can toughen polar high polymers such as modified nylon, so that the impact strength can be increased by 300% to 400%. Used as a chemical coupling agent in polymers filled with glass fibers or minerals to increase interfacial bonding capacity. In composite materials, it can be used to make cable shielding layer, food packaging bags, etc. Most of the existing production devices are relatively complicated. Ethylene-vinyl acetate-acrylic acid graft copolymer is used as a chemical coupling agent. The quality of the production device has important economic significance for improving product quality and reducing by-product content. Contents of the invention [0003] The purpose of the present invention is to provide a producti...
