Abstract

The invention relates to a combination of glass fiber infiltration agent, which comprises a film forming agent, a coupling agent and other promoters. The film forming agent is unsaturated and polyester type, and the unsaturated polyester is made into emulsion by emulsification, wherein, the unsaturated polyester is made from carboxyl sulfonate, polyol and polybasic acid by catalysis; the catalyst is titanate esters agent; the preparation technique includes the steps: 1 to 10 weight portions of carboxyl sulfonate and 50 to 150 weight portions of polyol react under the temperature of 150 to 200 DEG C; after being cooled, the obtained material is added with 40 to 95 weight portions of polybasic and titanate esters catalyst that is 0.05 to 1 percent of the mass of the film forming agent to react under the temperature of 160 to 230 DEG C; then the obtained material are cooled, crushed and made into emulsion; at last the emulsion is mixed with the coupling agent and other promoters to produce the infiltration agent. The invention has the advantages that: the unsaturated polyester emulsion is adopted as matrix and the sulfonate monomers with hydrophilicity is used for preparing the film forming agent, so the film forming agent has self-emulsifying function and can be dissolved in solution more easily; in addition, the titanate esters is employed as catalyst, which avoids the occurrence of polyester gel and better protects of glass fiber.

Description

technical field [0001] The present invention relates to a glass fiber sizing composition, in particular to a sizing composition for protecting glass fibers during the production of glass fibers for reinforced polymers. Background technique [0002] In the production and application of glass fiber and carbon fiber, the sizing agent plays an irreplaceable key role. It is used to enhance the adhesion, coating and pile resistance of the fiber bundle, smooth the fiber surface, increase softness, Abrasion resistance and easier winding with less damage when winding. [0003] Film-forming agent is the most critical component in sizing agent. It is used in the largest amount in sizing agent formula, accounting for 2-15%. Its performance directly determines the effect of sizing agent, and has an important impact on the performance and quality of raw silk and even yarn. Influence. [0004] The main function of the film-forming agent in the sizing formulation is to realize the bundled...
