Abstract

The invention discloses a water-based non-curable rubber asphalt coating and a preparation method thereof and belongs to the field of coatings. Modified rubber asphalt and mixed tackifying resin are emulsified, and a self-adhesive additive, an interface additive, an anti-freezing agent and an anti-ageing agent are compounded. The problem that the non-curable rubber asphalt waterproof coating cannot be applied until the coating is heated is solved, a process is simplified, and the application range of a product is widened. The initial adhesivity and persistent adhesivity of the coating are improved by using a tackifying resin emulsion. The problem that the non-curable rubber asphalt waterproof coating cannot be fully spread on a damp interface due to poor adhesivity is solved by using a silane interface agent, full-spreading seamless construction can be achieved, the hidden danger of water leakage or seepage is completely eradicated, and the permeation resisting performance meets the industrial standard. The water-based non-curable rubber asphalt coating is cured no longer by innovatively using the self-adhesive additive after coating construction is completed, and is good in puncture resistance and self-curing performance. Quick demulsification of the water-based non-curable rubber asphalt coating is achieved by adopting a double-component spraying technology.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based non-curing rubber asphalt coating and a preparation method thereof. Background technique [0002] Non-curing rubber asphalt waterproof coatings and coatings have good adhesion, extensibility, self-healing properties, good low temperature flexibility, and can achieve seamless construction in waterproof construction. It is a new type of asphalt waterproof material. However, the non-curing rubber asphalt waterproof coating has the following disadvantages: 1) It needs to be heated to 180°C for construction, which not only wastes energy, but also brings great inconvenience to the construction and limits the scope of application; heating construction consumes a lot of energy; 2) 180°C Under normal circumstances, asphalt fume also causes certain harm to the environment and construction personnel; 3) The adhesion effect of the wet interface is not ideal, and it cannot be directly pa...
