Abstract

The invention belongs to the technical field of glass fiber processing and specifically relates to an epoxy resin modified starch film-forming agent. The method comprises the following steps: utilizing yeast to consume citric acid; slowly releasing cupric ions combined with citric acid and reducing cupric ions by using L-ascorbic acid; adsorbing the reduced copper nanoparticle by poly (styrene-acrylic acid), thereby acquiring the dry bottom precipitate; heating and pasting the corn starch; utilizing a potassium hydroxide solution to disperse the amylose in the corn starch and then dissolving in a sodium chloride solution; centrifugally separating and then mixing and refining the supernatant containing the amylose and n-butyl alcohol; by using sodium hydroxide as a catalyst, reacting the refined corn starch with 3,4-epoxy cyclohexyl methyl 3,4-epoxy cyclohexyl formate, thereby acquiring epoxy resin modified refined corn starch; and ball-milling and mixing the epoxy resin modified refined corn starch with the dry bottom precipitate, thereby acquiring the epoxy resin modified starch film-forming agent. The epoxy resin modified starch film-forming agent provided by the invention has excellent film-forming property, low use viscosity and high storage stability.

Description

technical field [0001] The invention belongs to the technical field of glass fiber processing, and in particular relates to an epoxy resin modified starch film-forming agent. Background technique [0002] Glass fiber has a series of excellent characteristics such as high temperature resistance, light specific gravity, good insulation, low moisture absorption and small elongation. In the production of glass fiber, sizing agent is an indispensable auxiliary. The sizing agent is composed of film-forming agent, coupling agent, lubricant, antistatic agent, etc. Among them, the film-forming agent is the most critical component in the sizing agent, and its performance directly determines the effect of the sizing agent. Yarn performance and quality will have an important impact. It is an important part of the sizing agent and accounts for the largest proportion in the sizing agent. Its function is to protect the glass fiber during the production and processing of the glass fiber, a...
