High-performance glass fiber soakage agent

Abstract

The invention discloses a high-performance glass fiber soakage agent, and relates to the technical field of glass fiber production. The high-performance glass fiber soakage agent comprises components of 4.0-4.4 mol of dihydric alcohol, 1.5-2.5 mol of polyethylene polyamine, 0.5-1.0 mol of monoethanolamine, 1.0-2.0 mol of phthalic anhydride, 1.0-2.0 mol of glacial acetic acid, 1.5-2.5 mol of maleic anhydride, 0.5-1.0 mol of adipic acid and 0.1%-0.5% in percentage by weight of p-toluenesulfonic acid. The soakage agent prepared from the components proportionally has excellent wettability and can be well combined with glass fiber, and the reinforcement effect is very good; high-boiling-point substances of polyethylene polyamine and ethylene glycol are factory leftover bits, waste is turned into treasure, and phthalic anhydride, maleic anhydride and glacial acetic acid are all industrial common raw materials and are cheap, so that the production cost is lower, the whole production technology is simple, the thermal stability is good, the use is convenient, and storage and transportation are easy.

Description

technical field [0001] The invention relates to the technical field of glass fiber production, in particular to a high-performance glass fiber sizing agent. Background technique [0002] Disperse glass fiber in water or water alcohol or ester solution medium, and then be used to produce glass fiber insulation packaging materials, glass fiber mat, especially glass fiber mixed with polymer resin fiber to make high-strength glass such as glass fiber reinforced resin Fiber composite material is an important field of modern glass fiber application, and has broad market prospects and development prospects. [0003] Most of the currently commonly used water-dispersible glass fiber sizings use a single compound of amines or alcohols or a mixture of nonionic or cationic surfactants as a dispersant. Its shortcomings are: it is difficult to adjust according to the actual situation of industrial production, and it cannot meet the actual needs of dispersing various kinds of glass fibers...

Problems solved by technology

Its shortcomings are: it is difficult to adjust according to the actual situation of industrial production, and it cannot meet the actual needs of dispersing various glass fibers of different types and chemical compositions or different dispersion media of glass fibers

[0004]In the past, most of the sizing agents in the field of glass fiber used urea as a humectant, which has poor thermal stability and is prone to odor at high temperatures, which seriously affects the use of glass fiber , and it is easy to cause environmental pollution. The application number is CN201010252613.6, which discloses a glass fiber lubricant, a dispersant composed of two different nitrogen-containing surfactants, composed of one or more polyhydric or carbonyl alcohols, esters, Protective agent composed of acyl polymer, moisturizing agent composed of polyol mixture, lubricant, silane coupling agent commonly used in glass fiber industry, and the rest is distilled water or deionized water. This wetting agent is suitable for various alkali-free, Dispersion of medium-alkali glass fiber in water medium, the glass fiber treated by this product has good dispersion performance, good thermal stability and no pollution, but this kind of sizing agent has poor wettability, poor reinforcing effect, and high production cost
