Abstract

The invention discloses an epoxy non-cured rubber asphalt waterproof coating and a preparation method thereof and belongs to the field of coatings. The coating comprises a component A and a componentB, wherein the component A is prepared from asphalt, plasticizers, polymer modifiers and epoxy resin; the component B is prepared from epoxy curing agents. The problem that the non-cured rubber asphalt waterproof coating can be constructed after the coating is heated can be solved; the coating is energy-saving and environmentally friendly; the safety of constructors is ensured; the construction operation is simplified; the application range of the product is expanded; the coating is excellent in construction performance, does not need to be heated in the whole construction process, is excellent in high-temperature performance, can achieve obstacle-free construction under high temperature and low temperature, and is high in flexibility, high in elongation rate, excellent in creep property,high in self-healing capability, high in water channeling resistance and high in adhesion performance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an epoxy non-curing rubber asphalt waterproof coating and a preparation method thereof. Background technique [0002] Non-curing rubber asphalt waterproof coating is a new type of waterproof material with creep properties that maintains a viscous paste for a long time under the application state. bending fatigue damage or premature aging of the waterproof layer due to high stress; at the same time, due to the viscosity of the coating, it can well seal the capillary pores and cracks of the base layer, adapt to complex construction surfaces, and It can automatically find leaking parts, repair the damaged waterproof layer, solve the problem of water channeling in the waterproof layer, and greatly improve the reliability of waterproofing. However, the non-curing rubber asphalt waterproof coating has the following disadvantages. 1) It needs to be heated to 120-150°C before construction, which...
