Abstract

The invention provides a salt-tolerant non-cured waterproof coating, and belongs to the field of waterproof materials. The salt-tolerant non-cured waterproof coating comprises the following componentsin parts by weight: modified emulsified asphalt, isocyanate, polyethylene terephthalate particles, mica powder, polyisobutene, aluminium triphosphate, glycolylurea epoxide resin and an anionic surfactant. A preparation process comprises the following steps: mixing the modified emulsified asphalt, the isocyanate, the polyethylene terephthalate particles and the anionic surfactant in parts by weight to obtain a fused matrix; and then mixing the glycolylurea epoxide resin, the aluminium triphosphate and the fused matrix, heating the mixture for 40-70 minutes at the temperature of 180-200 DEG C,cooling to the temperature of 60-80 DEG C and then adding the mica powder and the polyisobutene, and then stirring 70-90 min. The coating is good in waterproofness, and has high salt tolerance, long waterproof characteristic can be maintained in a salty environment, and the adhesive property and the self-healing property are good.

Description

technical field [0001] The invention relates to the field of waterproof materials, in particular to a salt-resistant non-curing waterproof coating and a production process thereof. Background technique [0002] Non-curing rubber asphalt waterproof coating, made of rubber and asphalt as the main component, mixed with additives, is a waterproof coating that maintains a viscous paste within the service life. It has a prominent effect on the waterproof treatment of special parts such as deformation joints in construction projects, and is widely used in non-exposed building waterproof projects. [0003] Non-curing rubber asphalt waterproof coating is a kind of creep waterproof coating, which also has good bonding ability with metal, non-metal and concrete substrates, and has dual functions of waterproof and metal anticorrosion. Non-curing rubber asphalt waterproof coating has many advantages, such as: it will never harden, the cured content is more than 99%, does not contain vol...
