Problems solved by technology

[0004] Alkali-resistant chopped fibers have higher requirements for sizing agents. Most of the existing alkali-resistant glass fiber sizing agents use polyacrylate and vinyl acetate as the main film-forming agent, such as US Patent US.4289536. : 1. It can only meet the chopped fibers of 12㎜-24㎜, and the chopped fibers of 4㎜, 6㎜, and 8㎜ can produce a large amount of hairiness
2. Alkali resistance, water resistance and wear resistance are poor. After the cement mortar is stirred, some fibers will open and produce hairballs, resulting in low strength, uneven surface and rough surface of cement products, which cannot meet the requirements for use.

Abstract

The invention provides an alkali-resistant chopped glass fiber soakage agent and relates to a glass fiber surface treating agent containing an organic material. The alkali-resistant chopped glass fiber soakage agent is composed of a film-forming agent, a coupling agent, a lubricant, an antistatic agent, a pH regulator and de-ionized water, wherein the film-forming agent refers to a polyacrylate film-forming agent, an epoxy resin emulsion film-forming agent and a water soluble epoxy resin film-forming agent in the mass ratio of (2.0-20.0): (15.0-2.5): (1.0-10). The alkali-resistant chopped glass fiber soakage agent provided by the invention is suitable for 4 mm to 24 mm alkali-resistant chopped glass fibers; the alkali-resistant chopped glass fibers produced through impregnation in the soakage agent are excellent in alkali resistance, bundling, wear resistance, water resistance, choppability, dispersibility and antistatic property. In the mixing and stirring process of cement, the alkali-resistant chopped glass fiber soakage agent is capable of keeping the bundled state of the previous raw yarns without loosening.

Description

technical field [0001] The invention relates to a glass fiber surface treatment agent containing organic materials. Background technique [0002] Alkali-resistant glass fiber, also known as AR glass fiber, English: alkali-resistant glass fiber, is mainly used to strengthen the reinforced substrate of cement products (GRC for short), and is an ideal substitute for steel and asbestos in non-load-bearing cement components. Ordinary glass fibers are not alkali-resistant, and the main glass components of alkali-resistant glass fibers contain SiO 2 (58%-62%), Na 2 In addition to O (8%-13%), it also contains ZrO 2 (13%-16%), TiO 2 (4%-8%), it is characterized by good alkali resistance, can effectively resist the erosion of high alkali substances in cement, elastic modulus, impact resistance, tensile strength, and high flexural strength, 90% in 5% NaOH solution Corroded at ℃ for 72 hours, the weight loss is 4%. [0003] The glass component of the alkali-resistant fiber contains...
