Abstract

The invention discloses a water-based non-curing rubber asphalt coating and a preparation method thereof, belonging to the field of coatings. The invention emulsifies the modified rubber asphalt and the mixed tackifying resin, and then adds self-adhesive additives, interface additives, antifreeze, and anti-aging agents for compounding; it solves the problem that the non-cured rubber asphalt waterproof coating can only be constructed after heating, The process is simplified, and the scope of application of the product is expanded; the use of tackifying resin emulsion improves the initial tack and stickiness of the coating; the use of silane interface agent solves the problem of poor adhesion of non-curing rubber asphalt waterproof coating on the wet interface and cannot be fully paved It can realize full pavement and seamless construction, eliminate the hidden danger of water leakage and water seepage, and the water channeling resistance meets the industry standard; the innovative use of self-adhesive additives realizes that the coating will never cure after construction, and has strong puncture resistance and self-healing properties; One-part spraying process realizes rapid demulsification of water-based non-curing rubber asphalt coatings.

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...
