Embodiment 1

[0030] S1: After plasticizing natural rubber and thermoplastic styrene-butadiene rubber at 70-80°C, add half the weight of surfactant, and mix evenly;

[0031] S2: Enter the shearing machine after unloading, and perform rotary shearing at 500 rpm at 70°C;

[0032] S3: Add half of the weight of surfactant and half of the weight of water to the product obtained in S2, shear for 30 minutes, and then cut at 800 rpm for 5 minutes to obtain a rubber emulsion;

[0033] S4: Heating the asphalt to 140°C, keeping it warm, stirring evenly, then adding the remaining surfactant and water, stirring evenly to obtain an asphalt emulsion;

[0034] S5: Mix rubber emulsion, asphalt emulsion with acrylic resin, ethylene glycol ether, chlorinated polyethylene, silicon carbide whiskers, talcum powder, diatomaceous earth, stearic acid, polyacrylamide, ethylene-vinyl acetate copolymer, Mix plasticizer, defoamer, and pigment, stir evenly at 40°C, let cool, and get ready.

Embodiment 2

[0036] The difference with Example 1 is: the temperature in step S1 is 75°C; the temperature in step S2 is 75°C, and the rotating speed is 550rpm; in step S3, the rotating speed is 850rpm; the temperature in step S4 is 150°C; the temperature in step S5 is 45°C.

Embodiment 3

[0038] The difference with Example 1 is: the temperature in step S1 is 80°C; the temperature in step S2 is 80°C, and the rotating speed is 600rpm; in step S3, the rotating speed is 900rpm; the temperature in step S4 is 160°C; the temperature in step S5 is 50°C.

Abstract

The present invention provides a rubber asphalt waterproof coating material, and belongs to the technical field of coating materials. The coating material is prepared from the following raw materials, by weight, 20-35 parts of a natural rubber, 10-15 parts of a thermoplastic styrene-butadiene rubber, 5-10 parts of acrylic resin, 3-5 parts of ethylene glycol ethyl ether, 20-30 parts of asphalt, 5-10 parts of chlorinated polyethylene, 1-2 parts of silicon carbide crystal whiskers, 3-6 parts of talc powder, 2-4 parts of diatomite , 2-4 parts of stearic acid, 3-8 parts of polyacrylamide, 6-9 parts of an ethylene-vinyl acetate copolymer, 3-5 parts of a plasticizer, 1-2 parts of a defoaming agent, 8-15 parts of a pigment, 2-3 parts of a surfactant, and 40-50 parts of water. The waterproof coating material provided by the embodiments still has good watertightness and good mechanical property after high temperature and high humidity destruction.

Description

technical field [0001] The invention provides a rubber asphalt waterproof coating, which belongs to the technical field of coatings. Background technique [0002] Architectural waterproof coatings are solvent-based, water-soluble, water-emulsion coatings made of synthetic polymer materials, asphalt, polymer-modified asphalt, inorganic materials, etc., mixed with appropriate amount of additives, modified materials, filling materials, etc. Type or powder type waterproof material. Compared with waterproof coiled materials, waterproof coatings are simple and convenient to construct, suitable for any shape of base surface, and can form a dense and seamless coating film. Therefore, waterproof coatings have been widely used in various waterproof projects and have achieved rapid development. develop. [0003] Among them, rubber asphalt synthetic polymer waterproof coatings are occupying an increasing proportion in the application of waterproof engineering in my country. It has a ...
