Problems solved by technology

[0002] After asphalt emulsification and synthetic latex are combined as component A, calcium salt solution is used as component B, and the glue is sprayed from the nozzle of the spray gun through the airless double-gun spraying equipment and mixed outside the gun, instantly forming a waterproof layer on the original waterproof surface , there are many patents such as: "A Multifunctional Liquid Rubber Spray Coating, Preparation Method, Application Method and Special Equipment", "A Polymer Modified Emulsified Asphalt Composition and Its Preparation Method", "Flame Retardant Spray Quick-Setting Rubber Patents such as "Bitumen Waterproof Coating", "High Temperature Resistant Spraying Quick-Setting Rubber Waterproof Coating" and "Anti-corrosion Spraying Quick-setting Rubber Waterproof Coating" all introduce the production method of this kind of waterproof material. The final waterproof membrane of the main material is dark black and cannot be blended into other colors, which affects the aesthetics of the waterproof layer with a certain decorative effect. In addition, the tensile strength of the waterproof membrane based on asphalt is less than 1mpa, and the waterproof membrane Tensile rebound rate ≥ 10%, which cannot meet the performance in special environments
When emulsifying asphalt, the heated asphalt will also produce certain harmful volatiles, which will have a certain impact on the environment and producers

Abstract

The invention discloses a color-adjusting spraying rapid-hardening liquid rubber waterproof material. The color-adjusting spraying rapid-hardening liquid rubber waterproof material comprises liquid modified rubber and a curing agent, wherein the liquid modified rubber comprises latex, a viscosity increasing filler, cassava starch modified with a coupling agent, an auto-vulcanization bag, emulsifying rosin, an inorganic filler and color paste in parts by weight; and the curing agent is an anhydrous calcium chloride solution. The color-adjusting spraying rapid-hardening liquid rubber waterproof material has the advantages that a coating-type waterproof structure is formed on a waterproof base layer in a liquid spraying manner, the waterproof reliability is improved, connecting overlaid seams do not exist by one-step spraying, the color-adjusting spraying rapid-hardening liquid rubber waterproof material is similar to a conventional spraying rapid-hardening asphalt waterproof material, and as a waterproof membrane is semi-transparent, the color is easy to adjust; production equipment is simple, and investment is small; a waterproof material emulsion is stable and difficult to layer and separate; the elongation rebound rate which is less than or equal to 5% is beneficial to the creep resistance of the waterproof layer; and the tensile strength of a waterproof adhesive film reaches 1.8Mpa, which is twice as much as the previous strength; and the color-adjusting spraying rapid-hardening liquid rubber waterproof material has good adhesive force being higher than or equal to 0.3Mpa.
