Abstract

The invention belongs to the technical field of building waterproof materials, and in particular, relates to a non-curable rubber asphalt waterproof coating and a preparation method thereof. The non-curable rubber asphalt waterproof coating comprises the following raw materials in parts by weight: 35-65 parts of petroleum asphalt, 5-25 parts of a softener, 2-10 parts of styrene-butadiene block copolymer, 5-20 parts of tackifying resin, 5-25 parts of waste rubber powder, 5-20 parts of a filler and 0.5-3 parts of a surfactant. Cheap catalytic cracking oil slurry is introduced into the raw materials, fly ash collected from flue gas after coal combustion is used as a filler, and the prepared non-curable rubber asphalt waterproof coating can be guaranteed to have excellent high and low temperature performance, good extensibility, difficult curing, good cohesiveness, good flexibility, strong self-healing property and low cost. The invention also provides the preparation method, wherein the preparation method has the advantages of low cost, environmental protection, convenience, safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of building waterproof materials, and in particular relates to a non-curing rubber asphalt waterproof coating and a preparation method thereof. Background technique [0002] Non-curing rubber asphalt waterproof coating is a creeping waterproof coating. It is not a water-based coating, nor is it a solvent-based or reactive coating, but a solvent-free, non-film-forming one-component creeping coating. It has good bonding ability with metal, non-metal and concrete substrates, and has dual functions of waterproof and metal anticorrosion. It is suitable for municipal engineering, subway tunnels, dams, pools, road bridges, roofs, toilets, undergrounds Waterproofing and grouting plugging of other parts. Non-curing rubber asphalt waterproof coating can be used alone or combined with traditional waterproof materials. When used in combination, the waterproof reliability is higher. At present, the waterproof construct...
