Problems solved by technology

General-purpose waterproof slurry is rigid waterproof slurry with high hardness and wide application range. However, thick coating of rigid waterproof slurry is easy to crack, and there have always been many defects in the application of movable base. Although pure rigid waterproof coating has high strength, the base Activities will cause the waterproof coating to deform, and the deformation will lead to cracking. The thick coating of flexible waterproof coating will shrink and cause cracking. Therefore, in this case, a rigid waterproof material with high strength and not easy to crack is required.

Abstract

The invention discloses a water-based carbon fiber reinforcement polymer modified cementitious waterproof slurry. According to the invention, a rigid styrene-acrylic emulsion with good properties in compounding with cement, a glass transition temperature of 0 DEG C, a VOC content of less than 1 g / L, environmental friendliness, excellent waterproof performance and good rigidity is adopted to improve the waterproof performance and strength of a waterproof coating; a flexible styrene-acrylic emulsion with good wrapping ability and flexibility is also added to improve the workability of the waterproof coating; and carbon fiber grid cloth is used as a reinforcement to improve the flexibility and compactness of the waterproof coating.

Description

technical field [0001] The invention belongs to the field of waterproof coatings, in particular to a water-based carbon fiber reinforced polymer cement-based waterproof slurry. Background technique [0002] In recent years, with the development of the construction industry, the use of coatings has become more and more advanced and novel. Buildings are vulnerable to erosion and penetration by rainwater, groundwater and other moisture, which requires some waterproof materials. Therefore, waterproof materials have become an indispensable part of construction engineering structures. At the same time, waterproof coatings were born and developed rapidly. However, with the development of waterproof coatings in recent years, various manufacturers have introduced various waterproof coating products. There are many general-purpose waterproof grouts on the market. General-purpose waterproof slurry is rigid waterproof slurry with high hardness and wide application range. However, th...
