Lubricant composition for glass fiber reinforced engineering plastic and preparation method thereof

Abstract

The invention provides a lubricant composition for glass fiber reinforced engineering plastic. The lubricant composition for the glass fiber reinforced engineering plastic is prepared from, by mass, 10%-60% of components A, 10%-60% of components B and 5%-35% of components C, and the sum of mass percent of the component A, the components B and the components C equal to 100; the components A adopt one kind or multiple kinds of glyceride with a general formula (I), the components B adopt pentaerythritol ester, and the components C adopt organic silicon wax, wherein R1 and R2 represent an independent C8-C20 ester group or hydroxide radical, and at least one of R1 and R2 is the C8-C20 ester group. The invention further provides a preparation method of the lubricant composition for the glass fiber reinforced engineering plastic. The lubricant composition for the glass fiber reinforced engineering plastic is high in universality, convenient to use and capable of effectively reducing the glass fiber revealed phenomena of the glass fiber reinforced engineering plastic and improving surface gloss.

Description

technical field [0001] The invention relates to a lubricant composition, in particular to a lubricant composition for glass fiber reinforced engineering plastics and a preparation method thereof. Background technique [0002] Glass fiber reinforced engineering plastics have the advantages of good tensile, bending, compressive modulus of elasticity and creep resistance, stable size, good processing performance, short molding cycle, high production efficiency, and can be recycled, so its application fields have been continuously expanded , has been widely used in automobiles, machinery, electrical appliances, construction, boats, aerospace and other fields, especially in the increasing number of applications in automobiles. However, the polarity of glass fiber and engineering plastics is quite different, and the interface between the two phases is difficult to bond well, resulting in the phenomenon that glass fiber is often exposed on the surface of the product, which is commo...

AI Technical Summary

Problems solved by technology

[0005] The above existing patents all improve the compatibility between glass fiber and resin by adding grafts. Although the floating fiber of the product has been improved, the floating fiber phenomenon often occurs for injection molded products, and the processing efficiency is low. There is also a need for further improvement in surface gloss, etc.
