Abstract

The invention discloses an impregnating agent for high-strength industrial glass fibre spun yarns and a preparation method thereof. The impregnating agent comprises the following raw materials by weight percent: 4-5% of modified starch, 0.2-0.3% of hydrogenated vegetable oil, 0.72-1.02% of vegetable oil emulsifying agent, 0.4-0.5% of water-borne epoxy resin, 0.1-0.2% of softening agent, 2.0-2.5% of polyethylene glycol, 0.03-0.05% of glacial acetic acid, 0.4-0.6% of coupling agent and the balance of water, wherein the coupling agent is an aminosilane coupling agent; the emulsifying agent is a polyoxyalkyl emulsifying agent; and the softening agent is a cationic softening agent. The impregnating agent has the advantages that the impregnating agent can endow yarns with weaving performances needed when the yarns are used as industrial fabrics; the yarns have good wear resistance and high strength and are not easy to break in the weaving process; meanwhile, the bondability between the yarns and resins can be improved; and the impregnating agent is relatively simpler to prepare and is easy to achieve.

Description

technical field [0001] The invention relates to a sizing agent, especially a sizing agent for high-strength industrial glass fiber spun yarns. Background technique [0002] Glass fiber can be simply divided according to its fiber diameter and usage, and can be divided into two categories: roving and spun yarn. Roving generally uses reinforced / resin-type sizing, which is used for pipe winding, hand lay-up FRP, chopped strand mat, etc.; while spun yarn can be used for weaving electronic base fabrics, industrial fabrics (mesh fabrics) depending on the sizing used , wall coverings and other industrial fabrics). [0003] General industrial glass fiber spun yarns have high requirements for friction resistance and tensile strength. Generally, it is required to have excellent friction resistance and tensile strength greater than 0.5N / TEX, and sizing is very important in the glass fiber production process. It directly plays a decisive role in the performance of glass fiber. [000...
