Infiltration agent of chopped glass fiber for reinforcing cement

Abstract

The invention discloses an infiltration agent of chopped glass fiber for reinforcing cement. The infiltration agent comprises the following components by weight percent: (1) 0.2-1.5% of coupling agent which is combination of 3-amino propionic triethoxy silane and 3-methacryloyloxyethyl propyl trimethoxysilane; (2) 3.0-30.0% of a film-forming agent, which is crosslinked polyacrylic dispersion or combination of crosslinked polyacrylic acid dispersion and a bisphenol A epoxy emulsion with medium-high molecular weight, wherein the molecular weight of the epoxy resin in the bisphenol A epoxy emulsion with medium-high molecular weight is 1200-6000; (3) 0.01-2.0% of a nonionic lubricant; (4) 0.05-1.0% of organic antistatic agent; (5) 0.1-2% of pH value modifier; (6) 63.5-96.64% of deionized water. A glass fiber yarn produced by using the infiltration agent has the advantages of being good in bundling property, easy to chop, and resistant to alkaline corrosion of cement, the produced cement product is high in mechanical strength, and the product is bright and clean in appearance.

Description

(1) Technical field [0001] The invention relates to a chopped glass fiber sizing agent for reinforcing cement. (2) Background technology [0002] Glass fiber reinforced cement (GRC for short) is a new type of building material specially designed for steel structure buildings. Due to its advantages such as light density, high strength, good fire resistance, and fast construction, it can be used for floor slabs of steel structure buildings and interlayers, interior and exterior of light steel villas. Walls, stair treads. The glass fiber reinforced cement component is thin, with high stretch resistance, good impact resistance, low alkalinity, small free expansion rate, reliable crack resistance, stable quality, moisture resistance, heat preservation, flame retardant, sound insulation, sawing, drilling, It can be nailed, planed, and chiseled, and the wall surface is flat. The construction is simple, avoids wet work, improves the construction environment, and saves land resource...

Problems solved by technology

[0005] Aiming at the fact that the existing sizing agent cannot effectively solve the conflicting problems between the short-cut glass fiber resistance to alkaline corrosion in cement, product appearance and strength, the present invention provides a chopped glass fiber sizing agent for reinforcing cement. The glass fiber yarn produced by the agent has the advantages of good clustering, easy chopping, alkali corrosion resistance of cement, high mechanical strength of the produced cement products, and smooth appearance of the products.
