Abstract

The invention relates to a non-asphalt-based non-cured rubber waterproof coating and a preparation method thereof, and the coating is mainly prepared from the following components in parts by weight, wherein the components are shown in the description. The invention overcomes the defects that the existing non-asphalt-based non-curing rubber waterproof paint takes rubber, asphalt and softening oil as main components, the anti-aging performance, the high-temperature heat resistance and the low-temperature flexibility are insufficient, and a large number of harmful substances are volatilized in the construction process; through the synergistic effect of the softening oil, the petroleum resin, the thermoplastic elastomer and the high-temperature additive and the cooperation of other components, the coating has the advantages of high temperature and low temperature performances, aging resistance, excellent bonding performance with a base layer and a waterproof coiled material, good construction performance, safety, environmental protection and no peculiar smell.

Description

technical field [0001] The invention relates to a non-asphalt-based non-curing rubber waterproof coating and a preparation method thereof, which are applied in the field of waterproof coatings. Background technique [0002] The non-curing rubber waterproof coating will not cure for a long time after contact with the air, and will always maintain the characteristics of viscous colloid. It has strong self-healing ability, is sticky when touched, and is difficult to peel off. It can seal the cracks and pores of the base layer. The coating can solve the cracking stress caused by the base layer. The problem of cracking, fatigue damage or premature aging of the waterproof layer caused by the transfer to the waterproof layer can solve the problem of poor compatibility when the waterproof membrane and waterproof coating are used together, and can adapt to complex construction operations. [0003] However, the traditional non-curing rubber waterproof coating is mainly composed of rub...
