Problems solved by technology

The weft yarns of the early medium-alkali glass fiber grid fabrics generally use ply rovings produced by sizing systems such as "711", "681", "SR-1", and "811", which have low weaving production efficiency and low production efficiency. The weaving strength of the gray cloth produced is low, the flatness and density of the cloth surface are poor, and there are many hairs, etc. The development of suitable medium-alkaline roving can better solve the above problems

Embodiment 1

[0018] 1: Put 190g of isophthalic acid, 52g of propylene glycol, 73g of diethylene glycol, 87g of HPHP, 99g of CHDM, 600090g of polyethylene glycol, and 0.8g of dibutyltin dilaurate into a 1000ml four-necked flask, and heat up the reaction under nitrogen protection. To resorcinol, acid value below 5mgKOH / g, lower the temperature.

[0019] 2: Throw in 65g of maleic anhydride, 64g of oxalic acid, and 0.01g of hydroquinone, heat up the reaction, control the acid value to 20-25mgKOH / g, and when the reaction is over, add 75g of propylene glycol methyl ether and stir evenly.

[0020] 3: With the stirring speed of the high-speed disperser at 2000 r / min, slowly add deionized water dropwise until it becomes an emulsion, and adjust the solid content to 40%, that is, the polyester emulsion for medium-alkali direct untwisted roving sizing agent is prepared. film agent.

Abstract

The invention relates to a polyester emulsion film former for a medium-alkali direct twistless roving impregnating compound. A preparation method of the polyester emulsion film former for the medium-alkali direct twistless roving impregnating compound comprises the following steps: carrying out a condensation polymerization reaction of hydrophilic diacid or dialcohol to synthesize hydrophilic unsaturated or saturated polyester, feeding and mixing the unsaturated or saturated polyester, a solvent and deionized water according to a feeding ratio of 10:1:14, and adopting a phase reversal method to prepare the polyester emulsion film former for the medium-alkali direct twistless roving impregnating compound. The polyester emulsion film former has the advantages of good stability, good wire drawing operationality, good binding bunching to glass fibers after the film formation, fast permeation and less hairiness, and is suitable for the medium-alkali direct twistless roving impregnating compound.

Description

technical field [0001] The invention relates to the field of polyester emulsion film-forming agents, in particular to a polyester emulsion film-forming agent used as a medium-alkali direct untwisted roving sizing agent. Background technique [0002] Fiberglass mesh has the characteristics of light weight, high strength, temperature resistance, alkali resistance, corrosion resistance, and crack resistance, so it is widely used in external wall insulation systems and internal wall reinforcement, decoration, etc. After years of development in China, relatively complete construction methods and standards have been formed. Under the guidance of the government and the industry this year, all kinds of buildings, especially high-rise buildings, use glass fiber mesh for the construction of external wall insulation systems and interior wall reinforcement and decoration, making the domestic alkali-resistant glass fiber mesh consumption Rapid growth has formed an annual consumption of ...
