Embodiment 1

[0076] Embodiment 1: a kind of non-cured rubber asphalt waterproof coating, each component and its corresponding parts by weight are shown in Table 1, and are prepared by the following steps:

[0077] Step 1: Add the asphalt into the emulsification equipment to melt, keep the temperature at 130-150℃, slowly add anionic emulsifier (half dose), octadecyl fatty alcohol under stirring state, and then slowly add light stabilizer and toughening agent , kept at 120°C to obtain the first mixture;

[0078] Step 2, add water to another emulsification device, heat up to 60°C, add anionic emulsifier (the other half dose) and sodium lauryl sulfate under uniform stirring to make it dissolve evenly, then add it under high-speed stirring. Bentonite, stir evenly to obtain the second mixture;

[0079] Step 3, under high-speed stirring, slowly add the first mixture into the second mixture, stir evenly, and cool to 50°C to form the third mixture;

[0080] Step 4: Slowly add the neoprene latex a...

Abstract

The invention discloses a non-cured rubber asphalt waterproof coating and a preparation method thereof. The waterproof coating comprises the following raw materials in parts by weight: 95-105 parts of pitch, 1.8-2.2 parts of an anionic emulsifier, 1.2-1.8 parts of Eighteen carbon fatty alcohol, 7-13 parts of a flexibilizer, 2-3 parts of lauryl sodium sulfate, 3-7 parts of bentonite, 58-62 parts of neoprene latex, 38-42 parts of compounded latex, 10-13 parts of a thickener, and 48-52 parts of water; and the solid content of the compounded latex is 40%-50%. The waterproof coating is cold-applied, can be blade-coated or rolling-coated, is widely suitable for places of roofs, garages and basements, factory buildings and the like, especially suitable for places such as substations, pharmaceutical factories, oil refinery and the like requiring fire proofing and explosion proofing, is safe and free from fire disaster risks, capable of saving a great amount of fuel gas energy, and incapable of releasing carcinogenic gases such as phenol, naphthalene, anthracene, benzene, pyrene, chlorine and the like, thus being environment-friendly and pollution-free. Under the action of piezoresistivity and creep resistance performances, the damaged part can be self-repaired so as to always keep the completeness of a waterproof layer, so that the waterproof performance is excellent.

Description

technical field [0001] The invention relates to the technical field of waterproof coatings, and more particularly, to a non-cured rubber asphalt waterproof coating and a preparation method thereof. Background technique [0002] The traditional waterproof materials mainly include flexible waterproof materials such as waterproof membranes, waterproof coatings, sealing ointments, and rigid waterproof materials mainly based on cement substrates, with the addition of liquid chemicals and other additives. Mainly used for roof waterproofing, underground moisture-proof, pipeline anti-corrosion, channel anti-seepage, underground waterproofing, etc. [0003] In the Chinese invention patent with publication number CN104031444A, a polymer modified asphalt waterproof coating is disclosed, which is composed of the following components by weight: 30-50 kg of deionized water, 15-25 kg of titanium dioxide, 10-25 kg of silicon dioxide 20 kg, defoamer 4-6 kg, modifier 4-6 kg, thickener 4-6 kg...
