Abstract

The invention discloses a preparation method of a mold release agent for a wood-plastic composite material, and belongs to the technical field of polymer materials. The mold release agent is preparedfrom the following materials in parts by weight: 8 to 10 parts of a plasticizer, 3 to 5 parts of phospholipid, 5 to 8 parts of an emulsifier, 8 to 10 parts of a dispersant aqueous solution, 8 to 10 parts of pretreated dicyclohexyl peroxydicarbonate, and 200 to 300 parts of water; the preparation method comprises the steps of adding the water into a polymerization kettle, heating, then adding the plasticizer, the phospholipid, the emulsifier, the dispersant aqueous solution, pretreated dicyclohexyl peroxydicarboxylate, stirring and mixing, introducing nitrogen containing vinyl chloride, keepingtemperature and pressure and stirring for reaction, then, adding a terminator with the mass being 0.03 to 0.05 times of that of the plasticizer, releasing pressure, and cooling and discharging to obtain the release agent for the wood-plastic composite material. The release agent for the wood-plastic composite material prepared by the preparation method provided by the invention has the characteristic of excellent mold release effect, and has broad prospects in the development of the polymer material technology industry.

Description

technical field [0001] The invention discloses a preparation method of a release agent for wood-plastic composite materials, belonging to the technical field of polymer materials. Background technique [0002] The release agent is a functional substance between the mold and the finished product. Mold release agents are chemically resistant and do not dissolve when in contact with different resin chemical compositions, especially styrene and amines. The release agent also has heat and stress resistance, and is not easy to decompose or wear; the release agent adheres to the mold and does not transfer to the workpiece to be processed, and does not hinder painting or other secondary processing operations. Due to the rapid development of injection molding, extrusion, calendering, molding, lamination and other processes, the amount of release agent has also increased significantly. A release agent is an interface coating used on two surfaces that tend to stick to each other to m...
