Problems solved by technology

Since the existing waterproof coatings are all cured, although they have certain waterproof performance and bonding strength, their tear resistance is poor. When cracks appear in the base layer of the coated object, the coating film will also be destroyed.
Once the coated base layer is deformed and cracked, it will cause the coating film to crack and lose its waterproof function; while the construction of waterproof membranes has many lap joints, it is easy to cause the lap joints to bulge and cause water to flow, and it is not resistant to cracking of the base layer Ability to make the membrane crack and lose its waterproof effect
In recent years, with the development of social economy, non-curing rubber asphalt materials have appeared. Due to the characteristics that non-curing rubber asphalt materials will not solidify for a long time after construction, people pay more and more attention to them. Applied research is almost blank
[0003] Therefore, research and development of a building waterproof construction method of non-cured rubber asphalt, using the advantages of non-cured rubber asphalt will not cure for a long time after construction, to maintain the original performance of waterproof materials for a long time, to alleviate the resistance of existing cured waterproof coatings. The cracking ability is poor. Once the coated base layer is deformed and cracked, the coating film will lose its waterproof function. It is very necessary and urgent to significantly improve the life of the waterproof layer after construction.

Abstract

The invention provides a building waterproof construction method using non-cured rubber asphalt and application thereof, and relates to the technical field of waterproof layer construction methods. According to the building waterproof construction method, the advantage that the non-cured rubber asphalt cannot be cured for a long time after construction is utilized, the original property of a waterproof material can be maintained for a long time, and the problems that the anti-cracking ability of an existing curing type waterproof coating is poor, and once a coated base layer deforms and cracks, the waterproof function of a coated film can be lost are solved. Meanwhile, the method is simple and easy to operate, the construction period can be greatly reduced, and the labor cost invested during construction is saved. The building waterproof construction method can be widely applied to waterproof repair of non-exposed waterproof layers, waterproof linings and non-exposed roofs of buildingsor structures of subways, tunnels, culverts, dams, water ponds, road bridges, toilets, underground projects and the like.

Description

technical field [0001] The invention relates to the technical field of waterproof layer construction methods, in particular to a building waterproof construction method using non-cured rubber asphalt and its application. Background technique [0002] At present, in the waterproof construction design of building waterproofing projects, the waterproof coatings are all solidified, that is, the coating film is cured after the medium volatilizes to play a waterproof role; while the waterproof roll is covered on the base layer to play a waterproof role. Because the existing waterproof coatings are all curing type, although they have certain waterproof performance and bonding strength, their tear resistance is relatively poor. When cracks appear in the base layer of the coated object, the coating film is also destroyed thereupon. Once the coated base layer is deformed and cracked, it will cause the coating film to crack and lose its waterproof function; while the construction of wa...
