Abstract

A spray-on plastic release agent, which is composed of A solution, B solution, C solution and D solution according to the volume ratio of 15~35:1.6:0.5:0.8~1; the A solution is prepared by the following method Preparation: get 100ml ethyl acetate, 15ml eucalyptus oil and 3ml glycerol carbonate and mix it; the B solution is made by mixing 100mL ethyl acetate and 15mL eucalyptus oil; the C solution is 10mL simethicone Prepared by dissolving in 100mL ethyl acetate; the D solution is a mixed surfactant solution prepared by dissolving 10g sodium stearate and 10g Tween-80 in 100mL water. The mold release agent is used for mold release of plastic products and has good smoothness, isolation and mold release, high and low temperature resistance, chemical stability, no corrosion, non-toxic environmental protection, easy operation, and good use effect.

Description

technical field [0001] The invention relates to a spray-coated plastic release agent, which belongs to the technical field of chemical products. Background technique [0002] A release agent is an interface coating used on two surfaces that tend to stick to each other to make the surface easy to release, smooth and clean. Mold release agents are used in a wide variety of molding operations including metal die casting, polyurethane foams and elastomers, glass fiber reinforced plastics, injection molded thermoplastics, vacuum foamed sheets and extruded profiles. In molding, sometimes other plastic fillers such as plasticizers will seep into the interface, and a surface remover is needed to remove it. Mold release agents are chemically resistant and do not dissolve when in contact with the chemical composition of different resins (especially styrene and amines). The release agent also has heat and stress resistance, and is not easy to decompose or wear; the release agent adhe...
