preparation example Construction

[0066] The preparation method of the glass fiber sizing agent of the present application comprises the steps:

[0067] 1S: Add 35% to 45% water of the total amount of wetting agent in the container, then add the pH regulator, stir for 3 to 5 minutes, then slowly add the coupling agent at a speed of 100-200 g / s, Stir for 20-30 minutes until the coupling agent is evenly dispersed;

[0068] 2S: Dissolve the first lubricant in 5-10 times the amount of water at 40-60°C, stir and dilute it and add it to the container; use 2-3 times the amount of water as the second lubricant Dilute and add to the container;

[0069] 3S: Dilute the film-forming agent with 2 to 3 times the amount of water and add it to the container;

[0070] 4S: Dilute the wetting agent with 2 to 3 times the amount of water and add it to the container;

[0071] 5S: Dilute the additive with 2 to 3 times the amount of water and add it to the container; make up the remaining water and stir evenly; add a pH adjuster f...

Abstract

The invention discloses a glass fiber impregnating compound. The glass fiber impregnating compound comprises effective components and water, the solid content of the impregnating compound is 5.5-12%; the effective components comprise a coupling agent, a wetting agent, an auxiliary agent, a lubricant, a film-forming agent and a pH value regulator; the impregnating compound comprises the following effective components in percentage by mass: 12-17% of a coupling agent, 2-4.5% of a wetting agent, 0.05-0.5% of an auxiliary agent, 7-14.5% of a lubricant, 60-74% of a film-forming agent and 3-5.5% of a pH value regulator, wherein the solid mass of the coupling agent accounts for 12-17% of the total solid mass of the impregnating compound; wherein the film-forming agent is one or a combination of more of epoxy resin emulsion and modified epoxy resin emulsion. A glass fiber product produced by coating the glass fiber impregnating compound has the characteristics of low resin absorption amount, less hairiness and good interface bonding with epoxy resin, and the prepared glass fiber reinforced plastic product is high in glass fiber content, high in mechanical strength and low in production cost, and meets various requirements of the glass fiber reinforced plastic product.

Description

technical field [0001] The present application relates to the technical field of glass fiber reinforced thermosetting resin, in particular to a glass fiber sizing agent and its preparation method, product and application. Background technique [0002] FRP is a composite material that uses glass fiber to reinforce unsaturated polyester, epoxy resin, vinyl resin, phenolic resin and other resin matrices, and uses glass fiber or its products as a reinforcing material. FRP has high hardness and light weight, and is a very good substitute for metal materials. Usually, glass fiber accounts for as high as 50-80% by weight in FRP products, and the rest is resin, filler and other components. Therefore, increasing the proportion of glass fiber in FRP products is the key to improving the mechanical properties of FRP products. At the same time, it can also reduce the proportion of resin, thereby greatly reducing manufacturing costs. [0003] At present, the existing glass fiber product...
