Problems solved by technology

[0003] At present, the waterproofing of underground projects mainly adopts traditional waterproof coiled materials and other types of waterproof coatings and waterproof coiled materials. During construction, the requirements for the waterproof base surface are high, and there must be no dust, moisture, etc., and the coiled material is easy to be damaged when the base surface is uneven. The integrity of the water leaks; traditional waterproof coatings such as polyurethane waterproof coatings have low construction efficiency due to the scraping process
Spraying quick-setting rubber waterproof coatings have been vigorously promoted and applied in recent years because of their advantages such as high spraying efficiency and fast initial setting speed. It is easy to produce tensile damage during application, resulting in a decline in waterproof performance, so its performance needs to be further improved. The purpose of this invention is to provide a high-strength spraying quick-setting rubber waterproof coating to solve the problem of its low strength performance

Abstract

Belonging to the technical field of chemical production, the invention in particular relates to a high strength spray quick-setting rubber waterproof paint, which comprises a component A and a component B. The component A is composed of the following materials by mass percentage: 50%-70% of emulsified asphalt; 30%-50% of macromolecular rubber latex; 5%-15% of powder filler; 0.1%-1% of a dispersant; 0.1%-1% of a flame retardant; and 1%-15% of a tackifier. The component B is a curing agent. After molding, the high strength spray quick-setting rubber waterproof paint provided by the invention hashigh strength and elastic recovery rate, does not easily cause tensile failure when applied to parts with large dynamic load displacement, has effectively improved waterproof performance, can achievehigh spraying efficiency, fast initial setting speed and the like on underground engineering waterproofing, and improves the construction efficiency.

Description

technical field [0001] The invention belongs to the technical field of chemical production, and in particular relates to a method for preparing a high-strength spray-coated quick-setting rubber waterproof coating. Background technique [0002] With the vigorous development of the national economy, the construction of domestic infrastructure is becoming more and more complete. In recent years, the construction of underground space has been vigorously developed in China, including the construction of urban underground utility corridors, subways, and high-speed railway networks in the central and western regions. The waterproofing of underground engineering construction is very important, and the quality of waterproofing works is directly related to the operation of facilities in underground engineering. [0003] At present, the waterproofing of underground projects mainly adopts traditional waterproof coiled materials and other types of waterproof coatings and waterproof coil...
