Abstract

The invention provides a high-wettability glass fiber impregnating compound and a preparation method thereof. The high-wettability glass fiber impregnating compound is specifically prepared in steps as follows: (1), citric acid and oxalic acid are added to softened deionized water, the PH (potential of hydrogen) value of a solution is adjusted, the mixture is uniformly stirred until components are completely mixed, a non-ionic surfactant and a cationic surfactant are slowly added, the mixture is uniformly stirred until the components are completely dissolved, and a solution containing a coupling agent is obtained; (2), a lubricating agent, a cross-linking agent, a polyoxyethylene type surfactant, fatty acid ester sulfate and hydrolyzed chitosan are added to the softened deionized water, the mixture is heated and stirred until the components are completely dissolved, then the mixture is cooled at the room temperature, and an aid solution is obtained; (3), waterborne epoxy resin with epoxide equivalent being 415-437 and waterborne polyurethane in the volume ratio being 1: (0.3-1) are added to the deionized water to be diluted, then the mixture is uniformly stirred, and a diluted tow collecting agent is obtained; (4), the aid solution and the diluted tow collecting agent are slowly added to the solution containing the coupling agent, uniformly stirred, left to stand and defoamed, and the high-wettability glass fiber impregnating compound is obtained.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a high wettability glass fiber sizing agent and a preparation method thereof. Background technique: [0002] Today, with the continuous development of the world's scientific and technological level, various high-strength and high-modulus fibers, such as glass fibers, carbon fibers, and basalt fibers, can be made into composite materials with other materials, and their applications are found in almost every field of life. However, the presence of sizing agent is very important for the manufacture and use of high-strength and high-modulus fibers, because the sizing agent acts on the surface of the fiber and has little effect on the fiber itself. , Broken wire and so on. With the increase in the number of textile yarns and the application of high-efficiency preventive equipment, the protective requirements for textile sizing are getting higher and higher. ...
