Abstract

The invention provides a wetting agent for a glass fiber twisted yarn of a glass-fiber reinforced polypropylene needled mat and a preparation method thereof. The wetting agent is prepared from a coupling agent, a lubricating agent, a film-forming agent A, a film-forming agent B, a film-forming agent C, a pH regulator and water, wherein the pH value is 3-9; the coupling agent is selected from a silane coupling agent; the lubricating agent is selected from cation ammonium salt lubricating agent or nonionic lubricating agent; the film-forming agent A is selected from waterborne polyurethane resin; the film-forming agent B is selected from acrylic emulsion; the film-forming agent C is selected from PVAC emulsion; the pH regulator is an acid. Compared with the prior art, the wetting agent has the characteristics of high compatibility with polypropylene resin, excellent yarn dispersibility, low felt contractibility, applicability for hard and soft use, high product strength, and the like, and can meet the market requirement.

Description

technical field [0001] The invention relates to a glass fiber sizing agent, in particular to a sizing agent for glass fiber plied yarns for reinforcing polypropylene needle felts. Background technique [0002] Domestically, yarns for reinforced polyester resin chopped strand mats are widely used, while foreign customers have higher requirements for environmental protection and higher product strength. Needle-punched mats for reinforced polypropylene resin are in great demand, and current glass fibers cannot To meet customer requirements for product performance. Contents of the invention [0003] The object of the present invention is to provide a sizing agent for glass fiber plied yarns for reinforced polypropylene needle felt. The hard plied yarns produced by using the sizing agent have good dispersibility, moderate softness and hardness, low hairiness, and shrinkage of felt surface. Small size, good compatibility with polypropylene resin, and high product strength. [...
