Problems solved by technology

Although the existing waterproof coating prepared by emulsified asphalt and rubber latex has certain waterproof performance and can play a certain waterproof effect, the tensile strength of the waterproof coating is low and the heat resistance is poor. The surface of the waterproof coating layer is sticky and easy to stick to feet, which will cause damage to the waterproof coating layer and inconvenience for construction workers to walk

preparation example Construction

[0050] According to the preparation and construction method of the above-mentioned waterproof coating, a continuous waterproof coating layer can be formed on the construction base surface, and the waterproof coating layer has higher tensile strength and better heat resistance.

[0051] Preferably, during the preparation and construction of the spraying quick-setting rubber asphalt waterproof coating, when the polymer latex is a modified polymer latex, the modified polymer latex is reacted with a carboxyl-containing polymer latex and a cross-linking agent that can react with a carboxyl group. When obtained, before step 101 is performed, the method may further include: mixing a carboxyl-containing polymer latex and a carboxyl-reactive cross-linking agent at 20-25° C. to obtain a modified polymer latex.

[0052] Based on the existence of the above-mentioned carboxyl reaction, the reaction between the carboxyl-containing polymer latex and the crosslinking agent is carried out at no...

Abstract

The invention provides a sprayed quick-setting waterproof rubber asphalt coating, and preparation and construction methods thereof. The sprayed quick-setting waterproof rubber asphalt coating comprises a component A and a component B, wherein the component A comprises anionic hard emulsified asphalt and a polymer latex, and the penetration degree of the anionic hard emulsified asphalt is 30 to 50;and the component B comprises a coagulant. Since the anionic hard emulsified asphalt is used in the component A, the prepared sprayed quick-setting waterproof rubber asphalt coating has the characteristics of high tensile strength, good heat resistance and low low-temperature flexibility, and is applicable to high-temperature construction environments and low-temperature environments.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a spraying quick-setting rubber asphalt waterproof coating and a preparation and construction method of the spraying quick-setting rubber asphalt waterproof coating. Background technique [0002] At present, in the field of rubber asphalt waterproof coatings, waterproof coatings can be prepared from various raw materials, and common waterproof coatings are prepared from emulsified asphalt and rubber latex. Although the existing waterproof coating prepared by emulsified asphalt and rubber latex has certain waterproof performance and can play a certain waterproof effect, the tensile strength of the waterproof coating is low and the heat resistance is poor. The surface of the waterproof coating layer is sticky and easy to stick to feet, which will cause damage to the waterproof coating layer and inconvenience for construction workers to walk.
