Problems solved by technology

[0010] (1) The sizing protective layer coated on the surface of the glass fiber has poor textile resistance and is prone to hairiness when unwinding and plying;
[0011] (2) The sizing agent coated on the surface of the glass fiber has poor clustering property, the bonding between the fibers is not strong, and it is easy to open the fibers when spraying under pressure, which affects the uniformity of dispersion;
[0012] (3) The stiffness is low, which affects the short-cut dispersion of fibers

Abstract

The invention relates to a glass fibre surface treating agent containing an inorganic material. An alkali-resistant glass fibre jet yarn impregnating compound disclosed by the invention comprises a film-forming agent, a lubricating agent, an antistatic agent and water, wherein the film-forming agent is a mixture of a polyacrylate film-forming agent, a water-soluble epoxy film-forming agent, polyvinyl acetate and an acrylate copolymer film-forming agent; and the mass ratio of the polyacrylate film-forming agent to the water-soluble epoxy film-forming agent to the polyvinyl acetate and to the acrylate copolymer film-forming agent is (3.0-10.0): (2.0-9.0):(4.0-10.0). By adopting the alkali-resistant glass fibre jet yarn impregnating compound disclosed by the invention, the alkali-resistant glass fibre jet yarn has good bundling property, lubricating property, and spinning property in the processing process; and the alkali-resistant glass fibre jet yarn has good choppability, dispersibility and antistatic property in the technical process of a reinforced cement product.

Description

technical field [0001] The present invention relates to a glass fiber surface treatment agent containing organic materials. Background technique [0002] The alkali-resistant glass fiber jet yarn is mainly used to strengthen the reinforcing material of cement products (referred to as GRC). After the wire drawing is coated with sizing agent, it is rolled into a raw yarn drum, and then dried at 120-160 ° C, unwinding and plied into continuous fibers. The fibers are chopped and dispersed on the abrasive tool by a spray gun under a certain air pressure. Therefore, it is necessary to use a sizing agent with excellent performance when making continuous fibers to ensure the clustering, stiffness and lubricity of the glass fibers in the unwinding and plying, and at the same time to ensure the short-cutting and dispersibility of the fibers in the jet. [0003] Existing alkali-resistant glass fiber jet yarn sizing contains (wt%) [0004] Polyvinyl acetate film former 15.0-30.0 [...
