Abstract

The invention provides a sizing agent for non-alkali glass fiber plied yarn for reinforced polypropylene needle felt and a preparation method thereof. The sizing agent consists of a coupling agent, a lubricant, a film-forming agent A, a film-forming agent B, Film-forming agent C, pH regulator and water are prepared, and the pH value is 3-9; the coupling agent is a silane coupling agent; the lubricant is a cationic ammonium salt lubricant or a non-ionic Lubricant; Described film-forming agent A is aqueous polyurethane resin emulsion; Described film-forming agent B is acrylic acid emulsion; Described film-forming agent C is PVAC emulsion; Described pH regulator is acid; Compared with the existing technology, the sizing agent of the present invention has good compatibility with polypropylene resin, good yarn dispersibility, small shrinkage of felt surface, soft and hard use, high product strength, etc., and can meet market demand.

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. [...
