Embodiment 1

[0024] a. Put 35kg of asphalt into the batching reaction kettle first, heat it to 90°C, then slowly add 10kg of water and 1kg of cationic emulsifier dodecyltrimethylammonium chloride into the heated asphalt reaction kettle, The cationic emulsified asphalt material is prepared through high-speed grinding by emulsification and grinding equipment;

[0025] b After the temperature slowly drops to 40°C, add 1kg of PH regulator AMP-95 additive, 3kg of defoamer, and stir at a medium speed;

[0026] c After the mixture of b is uniform, add 15kg of cationic butadiene styrene copolymer emulsion and 25kg of cationic styrene acrylate copolymer emulsion successively, after continuing to stir for 30 minutes, pack when the temperature drops to normal temperature;

[0027] The waterproof material implemented in this way has high elasticity - after the coating is dried and solidified into a film, the test tensile performance reaches 1154%. The tensile strength can reach 1.88Mpa—three times th...

[0029] a. Put 45kg of asphalt into the batching reaction kettle first, heat it to 90°C, then slowly add 15kg of water and 3kg of cationic emulsifier dodecyltrimethylammonium chloride into the heated asphalt reaction kettle, The cationic emulsified asphalt material is prepared through high-speed grinding by emulsification and grinding equipment;

[0030] b. After the temperature slowly drops to 40°C, add 2kg of PH regulator AMP-95 additive, 3kg of defoamer, and stir at a medium speed;

[0031] c. After the mixture of b is uniform, add 25kg of cationic butadiene styrene copolymer emulsion and 30kg of cationic styrene acrylate copolymer emulsion and continue stirring for 30 minutes, then pack it when the temperature drops to normal temperature.

[0032] The waterproof material implemented in this way has high elasticity - after the coating is dried and solidified into a film, the test tensile performance reaches 865%. The tensile strength can reach 1.93Mpa - 4 times that of trad...

Embodiment 3

[0034] a. Put 40kg into the batching reaction kettle first, heat it to 90°C, then slowly add 10kg of water and 1.5kg of cationic emulsifier dodecyltrimethylammonium chloride into the heated asphalt reaction kettle, And through emulsification and grinding equipment high-speed grinding for 1.5 hours, the cationic emulsified asphalt material is prepared;

[0035] b. Keep the temperature constant, add 1.5kg PH regulator AMP-95 additive, 3kg defoamer, and stir at a medium speed;

[0036] c. After the mixture of b is uniform, add 19kg of cationic butadiene styrene copolymer emulsion BS-405 and 26kg of cationic styrene acrylate copolymer emulsion 510TS in turn, and continue to stir for 30 minutes. When the temperature drops to normal temperature Just pack it.

[0037] The waterproof material implemented in this way has high elasticity - after the coating is dried and solidified into a film, the test tensile performance reaches 622%. The tensile strength can reach 1.79Mpa—6 times th...

Abstract

The invention relates to the technical field of waterproof materials, in particular to an ultrahigh-elasticity asphalt-based waterproof paint production method which includes the steps: a, throwing asphalt into a dispensing reaction kettle, heating the asphalt to reach 90 DEG C, adding water and dodecyl trimethyl ammonium chloride serving as a cationic emulsifier, and uniformly grinding raw materials by an emulsification grinding device to prepare liquid mixture; b, reducing the temperature of the mixture in the step a to 40 DEG C, adding PH (potential of hydrogen) regulators, AMP-95 auxiliaries and defoaming agents, and uniformly stirring the raw materials at an intermediate speed; c, uniformly stirring the mixture in the step b and then sequentially adding positive ion acrylonitrile-butadiene-styrene copolymer latex and positive ion styrene acrylate copolymer latex. The waterproof materials have a high tensile property, and the breaking elongation of a paint layer with a formed filmcan reach 1200% and is 4-6 times that of traditional paint.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, in particular to an implementation method of a super-elastic asphalt-based waterproof coating. Background technique [0002] With the application of waterproof materials, the technical solutions have become increasingly mature, and the application of waterproof materials has become more extensive. A variety of water-based waterproof materials have been produced in the industry, and there are also a variety of ultra-high elastic waterproof materials, but ultra-high elastic asphalt-based waterproof coatings Also seldom occur, especially good performance, the ultra-high elastic asphalt base waterproof coating that cost is low does not have especially. Contents of the invention [0003] The object of the present invention is to address the above-mentioned shortcomings, and to provide a production method of a waterproof material with stronger elasticity and higher cohesiveness—a product...
