Wet chopped strand immersion agent and preparation method thereof

Abstract

The invention relates to a wet chopped strand immersion agent and a preparation method thereof. The wet chopped strand immersion agent comprises 0.2-0.4wt% of acetic acid, 0.5-0.6wt% of coupling agent, 0.02-0.10wt% of cellulose ether, 0.01-0.08wt% of dispersing agent, 0.01-0.03wt% of lubricating agent, 0.002-0.008wt% of preservative and the balance of deionized water. During preparation, a component with the dispersion performance is added into the immersion agent, and the immersion agent is further matched with chemical raw materials used during wet mat dispersion of chopped strands, so that the appropriate lubrication and protection effects are realized during drawing, and the chopped strands further have better dispersion performance. The drawing operation can also ensure a stable state, and tows on the mat surface are reduced from about 3 per square meter to 0.1 and even 0 per square meter during the mat manufacturing process. The wet chopped strand immersion agent disclosed by the invention has low cost, and can a play a positive promoting role in enlarging the production of chopped strand mats of an enterprise, increasing the sales volume and creating profits.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a sizing agent coated on the fiber surface during the drawing process of glass fiber raw filaments. Background technique [0002] The production of glass fiber is inseparable from the sizing agent. The main function is to provide lubrication and protection to the raw silk and reduce the wear between the single filaments during the drawing process. The first type is a sizing agent suitable for textile; the second type is an enhanced sizing The third type is thixotropic sizing, which mainly reduces the water content in the raw fiber tube and the energy required to dry them and reduces the sizing component in the raw fiber. Migration on the barrel. The selection of sizing agent is mainly related to wire drawing operation, felt forming, post-processing performance and application. The performance of the existing chopped strand sizing agent is mainly suitable for glass fiber drawing ...

AI Technical Summary

Problems solved by technology

The selection of sizing agent is mainly related to wire drawing operation, felt forming, post-processing performance and application. The performance of the existing chopped strand sizing agent is mainly suitable for glass fiber drawing type, which is used for felting after wet chopped strands During the process, a large number of white "tows" appear on the felt surface, resulting in unqualified appearance quality of the felt surface. After users use it, it will also cause product appearance defects, resulting in quality claims

Because glass fiber manufacturers and manufacturers of the main emulsion components in the sizing agent are very confidential about the sizing agent, it is impossible to obtain similar technical information from open channels, and no similar technology has been found in domestic and foreign patent documents and paper databases.
