Abstract

The invention discloses a method of synthesizing a fluorine-containing demoulding additive with agricultural processing side product, cardanol. The method uses a natural and reproducible agricultural processing side product, cardanol, to synthesize a fluorine-containing ester demoulding additive, so that the method has abundant raw material source and low cost. The demoulding additive is added to a demoulding agent and can satisfy market demands of high-end fluorine-containing demoulding additives. The demoulding additive can improve demoulding efficiency and product processing quality, satisfies high-end market demands, and has excellent economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of mold release additive synthesis, in particular to a method for synthesizing a fluorine mold release additive by using cardanol, a by-product of agricultural processing. Background technique [0002] 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. Fluorine-containing compounds have very low surface energy and high thermal and chemical stability. Adding them to the release agent can enhance the stability of the quality of the release agent and improve the storage period. Moreover, the concentration of fluorine-containing compounds is low and the effect is Good, long service life, one spraying can be used for many times; fluorine-containing compounds have good mold release properties for high-viscosity raw materials,...
