Abstract

The invention discloses a starch type impregnating agent for alkali-free glass fibers. The impregnating agent is prepared from, by weight, 3-5 parts of corn starch,1-2 parts of triglyceride, 0.3-8 parts of fatty acid ester, 0.05-0.1 part of polyoxyethylene polyoxypropylene ether, 0.05-0.1 part of fatty acid polyoxyethylene amide, 0.1-1 part of a softening agent, 0.1-0.4 part of an antistatic agent, 0.3-0.6 part of modified epoxy resin, 0.05-0.12 part of a preservative and 0.0005-0.002 part of a defoaming agent. The impregnating agent improves the bonding property between yarn and matrix resinand the permeability of the resin.

Description

technical field [0001] The invention relates to the technical field of sizing agents, in particular to a starch-type sizing agent for alkali-free glass fibers. Background technique [0002] The sizing agent is a multi-phase special surface treatment agent coated on the surface of the glass fiber during the drawing process of the glass fiber, which is mainly composed of an organic emulsion or solution. It is an essential and important Material. It plays the role of bonding, clustering, lubricating and wear-resistant, and eliminating static electricity, etc., so that it can meet the processing performance requirements of the glass fiber precursor in the subsequent process. However, the currently used starch-type sizing agent has poor compatibility between the produced yarn and the matrix resin, and poor resin penetration. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to provide a kind of starch type sizing agent for no...
