Embodiment 1

[0068] Embodiment 1: a kind of preparation method of high-elastic rubber waterproof coating, each component and its corresponding parts by weight are as shown in Table 1, and comprise the following steps:

[0069] Step 1: Add petroleum asphalt into an emulsification pot, heat, melt and dehydrate, wait until the temperature drops to 130-150°C, slowly add octadecyl fatty alcohol, glyceryl monostearate and leveling agent under stirring to melt , remove impurities sinking into the bottom of the emulsification pot during heating and melting, keep warm at 120°C, add light stabilizer, toughening agent and coupling agent in sequence, and stir evenly to obtain the first mixture;

[0070] Step 2: Add water into another emulsification pot, raise the temperature to 60°C, add sodium lauryl sulfate and anionic emulsifier under stirring, and dissolve them evenly, then slowly add them under high-speed stirring at a temperature of 120°C °C, stir for 5 minutes to emulsify the first mixture, the...

Abstract

The invention discloses high-elasticity rubber waterproof paint and a preparation method thereof. The waterproof paint is mainly prepared from the following ingredients in parts by weight: 95 to 105 parts of petroleum asphalt, 1.8 to 2.2 parts of C18 fatty alcohol, 0.05 to 0.1 part of levelling agents, 0.95 to 1.05 parts of coupling agents, 1.4 to 1.6 parts of toughening agents, 45 to 55 parts of water, 0.05 to 0.15 part of anionic emulsifiers, 30 to 35 parts of styrene-butadiene latex, 15 to 20 parts of compounded latex, 2.5 to 3.5 parts of antifoaming agents, 2.5 to 3.5 parts of dispersing agents, 200 to 300 parts of heavy calcium carbonate and 24 to 33 parts of thickening agents. The waterproof paint does not need hot melting; after the preparation is completed, scraping coating or rolling coating can be performed; the high-elasticity rubber waterproof paint can be applied to occasions with fireproof and explosion-proof requirements, such as oil refinery plants; the safety is high; no fire hazard risk exists; a great number of coal gas energy sources are saved; carcinogenic gas such as phenol and naphthalin cannot be released; the environment is protected; no pollution is caused. Under the effects of compression sensitivity and creep properties, damage parts can realize the self restoration; the completeness of the waterproof layer can be always maintained; the waterproof performance is excellent.

Description

technical field [0001] The invention relates to the technical field of waterproof coatings, more specifically, it relates to a high-elastic rubber waterproof coating and a preparation method thereof. Background technique [0002] Traditional waterproof materials mainly include flexible waterproof materials such as waterproof membranes, waterproof coatings, and sealing ointments, as well as rigid waterproof materials that are based on cement substrates and added with liquid medicine and other additives. Mainly used for roof waterproofing, underground moisture-proofing, pipeline anti-corrosion, channel anti-seepage, underground waterproofing, etc. [0003] In the Chinese invention patent whose publication number is CN104031444A, a high polymer modified asphalt waterproof coating is disclosed, which consists 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, 4-6 kg of defoamer, 4-6 kg of modifier...
