The invention discloses a glass fiber impregnating compound which comprises effective components and water, and the effective components comprise a silane coupling agent, a film-forming agent, an antistatic agent, a softening agent and a pH value regulator; the film-forming agent is a mixture of epoxy emulsion and polyvinyl acetate emulsion; the softening agent is one or a mixture of more of a difatty acid amine condensation polymer, phthalic acid distearate, alkanolamide and polyoxyethylene fatty acid amide. According to the glass fiber produced by coating the impregnating compound, the physical and chemical properties of the surface of the glass fiber can be changed, and the flexibility and dispersion performance of the glass fiber are effectively improved, so that the glass fiber product has low hairiness and excellent antistatic performance; and meanwhile, the compatibility of the glass fibers and matrix resin can be effectively improved, so that the prepared glass fiber chopped strand mat material for the PHC automotive upholstery has the characteristics of uniform distribution of the glass fibers, soft mat surface, good adhesion performance, high tensile strength of the chopped strand mat and the like.
本申请公开了一种玻璃纤维浸润剂,包含有效组分和水,有效组分包含硅烷偶联剂、成膜剂、抗静电剂、柔软剂和pH值调节剂;成膜剂为环氧乳液和聚醋酸乙烯酯乳液的混合;柔软剂为双脂肪酸胺缩聚合物、苯二甲酸二硬脂酸脂、烷醇酰胺和聚氧乙烯脂肪酰胺中的一种或任意几种的混合。采用该浸润剂涂覆生产的玻璃纤维,能够改变玻璃纤维表面的物理和化学性质,有效提高玻璃纤维的柔软性和分散性能,使玻璃纤维产品具有低毛羽和优异的抗静电性能;同时能有效提高玻璃纤维与基体树脂的相容性,使得所制得的PHC汽车内饰件用玻璃纤维短切毡材料具有玻璃纤维分布均匀、毡面柔软、伏贴性能好和短切毡拉伸强力高等特点。
