High performance jetting treating compound for twistless roving

Abstract

This invention discloses a formula for high-performance glass roving wetting agent for spraying. The wetting agent comprises: coupling agent, lubricating agent, antistatic agent A, antistatic agent B, film-forming agent A, film-forming agent B, pH regulator and water. The content of water is 85-95 wt. % of the wetting agent. The effective components are 5-15 wt. % of the wetting agent. The loss on ignition is 0.5-1.5%. The wetting agent comprises: coupling agent 1-10 wt.%, lubricating agent 1-10 wt.%, antistatic agent A 1-5 wt.%, antistatic agent B 1-5 wt.%, film-forming agent A 10-85 wt.%, film-forming agent B 85-10 wt.%, and pH regulator 0.1-5 wt.%. Film-forming agent A and film-forming agent B are combined, and their total amount is fixed. Film-forming agent A and film-forming agent B are epoxy resin / polyester. The wetting agent has such advantages as high permeation speed, high spraying performance, and high antistatic performance. The product has such advantages as high glass fiber content, high production efficiency and low production cost.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced thermosetting resins, in particular to a high-performance roving sizing agent for spraying that meets the needs of high-end customers. Background technique [0002] In European and American countries, spraying technology is used to produce FRP products. Due to the improvement of environmental protection requirements, the styrene content of unsaturated polyester resin used in production has been continuously reduced, and gradually reduced from 40% styrene content to 30%, or even 28%. . The reduction of styrene content means that during the use of glass fiber, the soaking speed will become slower and slower, which greatly affects the production efficiency. The rise in oil prices has become an irreversible trend. The use of styrene in resins has been continuously reduced, the amount of fillers and glass fibers in FRP components has been increased, and the original (or reduced) manufac...
