Problems solved by technology

[0003] At present, the commercially available emulsified asphalt waterproof coatings have single function, low strength, poor elasticity, not dense enough, poor adhesion to the substrate, no resistance to sag, prone to serious defects such as "water channeling", etc., so water-based coatings are constantly improved The function of waterproof coating, improving its quality and technical level is still a very important task at present and in the future

Embodiment 1

[0028] A kind of preparation method of water-based reactive rubberized asphalt waterproof coating of the present invention:

[0029] Install the cement mortar mixer according to the routine, adjust the speed to a low speed gear, and adjust the stirring blade as close to the bottom of the cylinder as possible. Weigh 12.7Kg of cationic styrene-acrylic emulsion and 20.3Kg of cationic neoprene latex, add them into the mixing tank, start the mixer, stir for 5-10 minutes to mix the two emulsions evenly; weigh 0.3Kg of cationic emulsifier (JL-C01), non Add 0.5Kg of ionic emulsifier (OP-10) into the mixing tank, and stir for 5-10 minutes; then weigh 32.4Kg of cationic emulsified asphalt, add it into the mixing tank, and stir for 10-15 minutes; weigh 32.9Kg of superfine talcum powder , in the stirring state, slowly add a small amount into the mixing tank, and stir continuously for 40~50 minutes, so that the powder is completely and evenly dispersed in the liquid; weigh 0.5Kg of cationi...

Embodiment 2

[0036] Weigh 8.5Kg of cationic styrene-acrylic emulsion, 22.2Kg of cationic neoprene latex, 34.1Kg of cationic emulsified asphalt, 0.3Kg of nonionic emulsifier (OP-10), 0.3Kg of cationic emulsifier (JL-C01), 0.3Kg of cationic Defoamer (851) 0.5Kg, superfine talc powder 33.5Kg, cationic thickener (CT-450) 0.4kg. Operation process is identical with embodiment 1.

Embodiment 3

[0038] Weigh 13.9Kg of cationic styrene-acrylic emulsion, 18.1Kg of cationic neoprene latex, 35.3Kg of cationic emulsified asphalt, 0.4Kg of nonionic emulsifier (OP-10), 0.4Kg of cationic emulsifier (JL-C01), 0.4Kg of cationic Defoamer (851) 0.5Kg, superfine talc powder 31.0g, cationic thickener (CT-450) 0.4Kg. Operation process is identical with embodiment 1.

[0039] Precautions:

[0040] (1), base surface treatment:

[0041] If the concrete base surface is flat and solid, free of oil and water, and the temperature is between +5 and 40°C, it can be directly constructed (it is not suitable for construction in rainy and snowy days or when the temperature is lower than +5°C).

[0042] (2) If the concrete base surface is relatively loose and not firm, primer must be applied first. The primer is cationic styrene-acrylic emulsion: water = 1:5. After brushing the primer, the primer must be dry without wet marks before construction.

[0043] (3) The water-based reactive rubberi...

Abstract

The invention discloses aqueous reaction type rubber asphalt waterproof paint and a production method thereof. The paint is prepared by mixing the following substances as raw materials in parts by weight: 8.1 to 14.5 parts of cationic styrene acrylic emulsion, 30.4 to 35.9 parts of cationic emulsified asphalt, 18.2 to 22.3 parts of cationic chloroprene emulsion, 0.4 to 0.7 part of non-ionic emulsifier, 0.2 to 0.4 part of cationic emulsifier, 0.3 to 0.6 part of defoaming agent, 29.5 to 33.5 parts of superfine talcum powder, and 0.4 to 0.6 part of cationic thickening agent. The paint has a function of water channeling prevention function and sagging resistant performance, and has the advantages of excellent physical and mechanical properties, convenience in construction and high cost performance.

Description

technical field [0001] The invention relates to the field of building waterproof materials, in particular to a water-based reactive rubberized asphalt waterproof coating and a preparation method thereof. Background technique [0002] Waterproof coating is an indispensable building material in the field of modern architecture. With the rapid development of urban and rural construction in my country, the demand for waterproof materials is also increasing rapidly, and the performance requirements for waterproof coating products are also getting higher and higher. For example, environmental protection Requirements, as the national environmental protection regulations become more and more stringent, people pay more and more attention to environmental protection, and the development of waterproof coatings is also moving towards pollution-free, pollution-free, resource-saving, energy-saving, and low organic volatiles (VOC). The goal of follow-up, in the future, water-based coatings w...
