Glass fiber yarn efficient impregnating agent

Abstract

The invention relates to the technical field of glass fiber, in particular to a glass fiber yarn efficient impregnating agent. The glass fiber yarn efficient impregnating agent provided by the invention comprises the following components: 13 to 21 percent of epoxy resin emulsion, 16 to 24 percent of polyacrylic ester, 1 to 2 percent of ammonia water, 0.2 to 0.8 percent of a silane coupling agent,0.05 to 0.5 percent of an organosilicon lubricating agent, 0.05 to 0.7 percent of a cationic lubricating agent, 0.3 to 1.3 percent of a non-ionic lubricating agent, 0.5 to 1 percent of sodium dodecylbenzene sulfonate, 0.5 to 1 percent of imidazoline, 4 to 8 percent of gasoline, 0.3 to 0.9 percent of ammonium chloride, 0.08 to 0.8 percent of aliphatic diamine and the balance of deionized water. The glass fiber yarn efficient impregnating agent provided by the invention has good penetration effect, high moisturizing property and high heat stability, can give high mechanical property to the glass fiber yarn and realizes a good weaving effect.

Description

technical field [0001] The invention relates to the technical field of glass fibers, in particular to a high-efficiency sizing agent for glass fiber yarns. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns, which is equivalent to a hair. 1 / 20-1 / 5 of that, each bundle of fiber precursors consists of hundreds or even thousands of monofilaments. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other national economy fields. ...

Problems solved by technology

[0003] The sizing agent is an indispensable surface treatment material in the production of glass fiber. The quality of the glass fiber and the variety of varieties largely depend on the sizing agent. Without a good sizing agent, it is impossible to produce High quality and variety of glass fibers
