Problems solved by technology

However, during the curing process of this waterproof material, the cement shrinkage rate is relatively large, so the residual stress of the cured coating is relatively large. After a period of use, the paint film is prone to cracking, which affects the waterproof effect and reduces the service life.

Abstract

The invention discloses a crack-resistant inorganic waterproof material, which comprises the following raw materials by weight: 90.8-94.6 parts of a cementing material, 0.5-0.9 part of a flowing modifier, 1.5-3.5 parts of an anti-cracking agent, 2.4-3.2 parts of an organic additive, and 4-6 parts of an inorganic additive. According to the present invention, the shrinkage rate is low after the crack-resistant inorganic waterproof material is cured, the paint film formed after the curing does not easily crack, the service life is long, the waterproof effect is good, the crack-resistant inorganic waterproof material can be widely used in building levels, kitchens and bathrooms, basements and other waterproofing projects, and the normal construction can be performed in the wet environment.

Description

technical field [0001] The invention relates to the field of waterproofing, in particular to a crack-resistant inorganic waterproofing material. Background technique [0002] my country is a big country in cement production and application. With the increasing urban construction in our country, the construction of subways, underground shopping malls, civil air defense facilities, underground parking lots, and underground corridors, the waterproofing of engineering buildings has become increasingly prominent, and the demand for waterproof materials is increasing. Traditional waterproof materials are mainly polymeric organic materials such as asphalt and waterproof membranes. Compared with the life of the building, these materials have a relatively short waterproof time, and the construction process is complicated, which requires high construction personnel and pollution. Various reasons such as the environment and the like limit its application. The cement-based inorganic w...
