Problems solved by technology

[0003] However, due to different formula components, water-based rubber asphalt waterproof coatings will have various physical and chemical properties. The strength of the products produced by the current common formula is weak (less than 0.3MPa), and it is easy to peel off and break when subjected to a large external force. , and due to the low strength, there will be phenomena such as sticking tires and destroying the waterproof layer during construction
[0004] After research, it is found that a single emulsifier cannot meet the requirements of high-strength rubber asphalt waterproof coatings for emulsified asphalt, because a single emulsifier has a fixed HLB value, and it cannot meet the HLB range required for complex asphalt emulsification

Abstract

The invention discloses a high-strength rubber asphalt waterproof paint. The high-strength rubber asphalt waterproof paint is prepared from 55-65wt% of emulsified asphalt, 25-35wt% of modified latex, 5-10wt% filler and the like. The high-strength rubber asphalt waterproof paint is prepared from the following steps of adding the emulsified asphalt, the modified latex and the filler into a stirring cylinder, stirring for 20min at a high speed, standing for 1 hour and then filtering to obtain the rubber asphalt waterproof paint. According to the high-strength rubber asphalt waterproof paint disclosed by the invention, high-strength composite modified emulsion is used for modification. The high-strength rubber asphalt waterproof paint has the remarkable characteristics of high strength, perfect fit, high elasticity, seamlessness and the like and can be manually scrapped and coated; therefore, the defect that the strength of the traditional asphalt coating is insufficient is solved.

Description

technical field [0001] The invention relates to a building material, in particular to a waterproof coating, more specifically to a high-strength rubber asphalt waterproof coating. Background technique [0002] In recent years, the country has strengthened investment in infrastructure and has been emphasizing environmental protection, energy conservation and emission reduction, which has greatly increased the application of water-based waterproof coatings, and the demand is also very strong. Water-based rubber asphalt waterproof coatings have outstanding features such as normal temperature scraping, perfect fit, no seams, and cheap prices. Therefore, water-based rubber asphalt waterproof coatings are widely used in waterproof construction of infrastructure construction. [0003] However, due to different formula components, water-based rubber asphalt waterproof coatings will have various physical and chemical properties. The strength of the products produced by the current co...
