Problems solved by technology

[0004] The crude glycerol phase obtained by alcoholysis reaction separation has a mass percentage of glycerin of less than 80%, and also contains impurities such as methanol and saponified substances. The purification of crude glycerin generally includes: filtering, adding chemical additives, purification and distillation, etc. For use in cosmetics and other fields, further deodorization, bleaching, and ion exchange are required to eliminate trace substances in it. The treatment process is complicated and the cost is high

Abstract

The invention relates to a preparation method and an application of a composite material coupling agent, belonging to the chemistry technical field of composite materials and coupling agents. The preparation method comprises the following steps of: refining biodiesel byproduct crude glycerine; preparing a hydroxyl-terminated polyol aqueous emulsion with the refined glycerine, polyether polyol and butanedioic anhydride as main raw materials by adopting a method of combining an internal emulsifier and an external emulsifier; and blending the hydroxyl-terminated polyol aqueous emulsion with isocyanate to prepare the coupling agent. The coupling agent is used for preparing an agricultural residue / recycled plastic composite material.

Description

technical field [0001] The invention relates to a preparation method and application of a composite material coupling agent, in particular to a coupling agent prepared by using biodiesel by-product glycerol as a raw material, the coupling agent is used for preparing agricultural residues / recycled plastic composite materials, It belongs to the technical field of comprehensive utilization of agricultural residue resources, composite materials and coupling agent chemistry. Background technique [0002] In order to solve the current shortage of oil resources, domestic and foreign are actively developing renewable energy to replace petrochemical products, biodiesel is one of them. [0003] Biodiesel is a regenerative diesel oil obtained by alcoholysis (transesterification) process using vegetable oils such as oil crops, wild oil plants and engineered microalgae, animal oils, and food waste oil as raw materials. It is often methanol, so the chemical composition of biodiesel is a ...
