Abstract

The invention provides an acid-resistant non-cured waterproof coating, and belongs to the field of waterproof materials. The waterproof coating comprises the following components in parts by weight: modified emulsified asphalt, butadiene styrene rubber, styrene-butadiene segmented copolymer, dimethicone, hydrogenated rosin, aluminum triphosphate, epoxy resin and an anionic surfactant. The preparation technology comprises the following steps: mixing the modified emulsified asphalt, butadiene styrene rubber, styrene-butadiene segmented copolymer and the anionic surfactant in parts by weight to obtain a fused substrate; then mixing the epoxy resin and aluminum triphosphate with the fused substrate, heating at the temperature of 150 to 170 DEG C for 40 to 70 min, cooling to temperature of 60 to 80 DEG C, then adding dimethicone and hydrogenated rosin, and stirring for 70 to 90 min. The coating is good in waterproof performance and has relatively high acid resistance, long-lasting waterproof characteristic can be maintained in an acidic environment, and the adhesive performance and self-healing performance are preferable.

Description

technical field [0001] The invention relates to the field of waterproof materials, in particular to an acid-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 vo...
