Abstract
The invention discloses a polyester emulsion for a glass fiber impregnating agent and relates to the technical field of glass fiber production. The polyester emulsion comprises the following components in percentage by weight: 30-45% of m-phthalic acid, 3.0-6.0% of phthalic anhydride, 8-15% of fumaric acid, 10-20% of polyethylene glycol, 15-25% of neopentyl glycol, 25-35% of propylene glycol and 1.0-3.5% of hydroquinone. The polyester emulsion for the impregnating agent in the percentage by weight is stable in performance and long in service life. By adopting the polyester emulsion in the production process of glass fibers, the mechanical property, choppability, bundling property and impregnating rate of the glass fibers are greatly improved. Materials for preparation are wide in source and low in cost and the whole synthetic process is good in stability and high in efficiency.
Description
Technical field
The present invention relates to glass fibre production technical field, be specifically related to a kind of glass fiber infiltration agent polyester emulsion.
Background technology
The exploitation of glass fibre new variety, its key is treating compound technology, in treating compound, important component is membrane-forming agent, except fiber is shielded, it is to glass fibre stiffness convergency, choppability, dispersed, impregnabilities etc. play a part key, therefore, develop desired membrane-forming agent, just the fiberglass product made new advances can be developed, the R and D of glass fiber infiltration agent are paid attention to abroad very much, no matter Shi Mei OFC company or PPG company, or-67 companies of Japan or the company of Saint-Gobain of France all have strong scientific research and development center, a large amount of scientific payoffss is all had every year on treating compound variety development, simultaneously each major company also will pay every year and hugely be engaged in research about basic theory to each university, the current mainly polyvinyl acetate emulsion of China's glass fiber injection yarn membrane-forming agent, because polyvinyl acetate emulsion adopts polyvinyl alcohol as colloid protective agent, poor in conjunction with impregnability with matrix resin, therefore the polyester emulsion developing excellent performance is needed.
Summary of the invention
Problem to be solved by this invention is to provide a kind of glass fiber infiltration agent polyester emulsion of excellent performance.
To achieve these goals, the technical scheme that the present invention takes is a kind of glass fiber infiltration agent polyester emulsion of providing, comprise m-phthalic acid, phthalic anhydride, fumaric acid, polyoxyethylene glycol, newly defend glycol, propylene glycol and quinhydrones, the weight percent of described each component is m-phthalic acid 30 ~ 45%, phthalic anhydride 3.0 ~ 6.0%, fumaric acid 8 ~ 15%, polyoxyethylene glycol 10 ~ 20%, newly defend glycol 15 ~ 25%, propylene glycol 25 ~ 35% and quinhydrones 1.0 ~ 3.5%.
Preferably, the weight percent of described each component is m-phthalic acid 32%, phthalic anhydride 4.0%, fumaric acid 9%, polyoxyethylene glycol 11%, newly defends glycol 17%, propylene glycol 25% and quinhydrones 2.0%.
Preferably, the synthesis technique of described glass fiber infiltration agent is specially and heats up in dibasic alcohol and monounsaturated dicarboxylic acid input band rare gas element reactor; Start to stir after material all melts, pass into nitrogen, temperature control 180 ~ 200 DEG C, condensation is dewatered, and when acid number is lower than 80mgkoH/g, adds unsaturated dibasic acid, temperature controls between 200 ~ 230 DEG C, proceed reaction, when actual aquifer yield is close to calculated value, measures acid number; When acid number is lower than stopped reaction of lowering the temperature during 30mgkoH/g, adds stopper when cooling to 130 ~ 140 DEG C, then carry out emulsification; Control according to vibrin aqueous emulsion and final solid content, determine the total consumption of deionized water, 1/3rd water yields are dropped in emulsion reactor, is warmed up to 70 DEG C; Above-mentioned unsaturated polyester resin is put into hot water rapid stirring, resin becomes oyster white from brown color gradually, after continuing stir about 30min, remaining 2/3rds water yields is slowly added in 2h, water temperature controls between 60 ~ 70 DEG C, now, emulsion gradually becomes water colour oil phase by oil colours aqueous phase, then samples, emulsion as dissolved completely in cold water, do not occur floss, can cool to 40 DEG C, blowing obtains faint yellow thick polyester emulsion.
Adopt technical scheme of the present invention, adopt the treating compound polyester emulsion of this kind of composition proportion, the stable performance of product, long service life, after adopting this kind of polyester emulsion in the production process of glass fibre, its mechanical property, choppability, convergency and wetting velocity are obtained for reply and improve, preparation material source is extensive, with low cost, and whole synthesis technique good stability, efficiency is high.
