Abstract

The invention relates to a glass fiber continuous strand mat impregnating agent. The glass fiber continuous strand mat impregnating agent is prepared from a silane coupling agent, a lubricating agent,a main film-forming agent, an auxiliary film-forming agent, a pH regulator, an anti-electrostatic agent and deionized water, wherein the film-forming agent comprises water-based epoxy ester emulsion,epoxy modified polyester emulsion and polyvinyl acetate emulsion; the solid content of the impregnating agent is 4.0 to 12.0 percent. A glass fiber original tow coated with the impregnating agent haslittle static electricity and adjustable hardness, can be compatible with various types of resin, is high in resin penetration velocity and has high bondability with the resin. Continuous felt with different solubility can be obtained by adjusting the proportion of the film-forming agent, and the glass fiber continuous strand mat impregnating agent is suitable for various processes such as pultrusion, injection molding and GMT processes.

Description

technical field [0001] The invention belongs to the field of glass fiber sizing agents, in particular to a glass fiber continuous precursor mat sizing agent. Background technique [0002] In the glass fiber drawing process, it is necessary to coat a special surface treatment agent with a multi-phase structure mainly composed of an organic solvent emulsion or solution on the surface of the glass fiber. This kind of coating can not only effectively lubricate the surface of glass fiber, but also integrate hundreds or even thousands of glass fiber monofilaments into a bundle, and can also change the surface state of glass fiber. It can not only meet the processing performance requirements of the first process, but also promote the combination of glass fiber and reinforced polymer in composite materials. [0003] The sizing agent is very important to the production and application of glass fiber. If the sizing agent is not coated on the surface of the fiber during the high-speed...
