Problems solved by technology

[0003] However, the non-curing rubber asphalt waterproof coating currently on the market needs to be melted at a high temperature above 180°C during construction, and a large amount of asphalt fumes are generated during the construction process, which not only pollutes the air and destroys the atmospheric environment, but also poses a threat to the construction personnel on site. There are also health effects

Abstract

The invention relates to an environment-friendly non-curing water-resistant paint and a preparation method thereof. The environment-friendly non-curing water-resistant paint is prepared by mixing and melting a styrene-isoprene-styrene thermoplastic block copolymer, polyisobutylene, a softening agent, hydrogenated rosin, an anti-sagging agent, an anti-aging agent and the like. The environment-friendly non-curing water-resistant paint has excellent self-recovery property, creep properties, bonding property and stripping resistance, can fill and seal capillary bores and cracks in the base layer, and prevents the phenomenon of water channeling of the water-resistant layer. The maximum melting temperature during construction is 120 DEG C; and the environment-friendly non-curing water-resistant paint does not generate any harmful volatile matter, has the advantages of high safety, environment friendliness and no pollution, and can adopt the mechanical spray coating or artificial scratch coating construction mode.

Description

technical field [0001] The invention relates to a waterproof coating and a production process thereof, in particular to a waterproof, moisture-proof and anti-corrosion non-curing waterproof coating used in roofing, underground, indoor, tunnel and other fields and a preparation method thereof. Background technique [0002] The leakage rate of my country's buildings has been high in recent years. One of the main reasons is that the waterproof layer and the base layer cannot achieve 100% microcosmic bonding. Once there is a leak somewhere, water channeling will occur, which will lead to the failure of the entire waterproof layer. . "Water channeling" has always been a waterproof problem that people are most concerned about. In order to solve this problem, non-curing rubber asphalt waterproof coatings came into being. Non-curing rubber asphalt waterproof coating has self-healing and creep properties, maintains good viscosity within the service life cycle, does not cure for a lon...
