Abstract

The invention discloses a wetting agent, which is characterized in that it is prepared from the following components by weight: 100 parts by weight of starch, 10-15 parts by weight of hydrogenated vegetable oil, 2-4 parts by weight of dibutyl phthalate, 3-4.5 parts by weight of paraffin wax, 25-35 parts by weight of water-soluble epoxy resin, 8-15 parts by weight of polyether polyol lubricant, 4-8 parts by weight of auxiliary agent, and 600-800 parts by weight of water. The invention can improve the physical and chemical properties of the glass fiber textile yarn, increase the tensile strength and hardness, and solve the problem of broken filaments.

Description

technical field [0001] The invention relates to the technical field of glass surface coating, in particular to a wetting agent coated on the glass surface. Background technique [0002] In the glass fiber drawing process, it is necessary to coat a special surface treatment agent with a multi-phase structure mainly composed of an organic solvent emulsion or solution on the surface of the glass fiber. This kind of coating can not only effectively lubricate the surface of glass fiber, but also integrate hundreds or even thousands of glass fiber monofilaments into a bundle, and can also change the surface state of glass fiber. It can not only meet the processing performance requirements of the first process, but also promote the combination of glass fiber and reinforced polymer in composite materials. [0003] The sizing agent is very important to the production and application of glass fiber. If the sizing agent is not coated on the surface of the fiber during the high-speed d...
