Problems solved by technology

[0002] The waterproof materials in the prior art include modified asphalt waterproof coatings. The use of various polymer modified asphalt can greatly improve the performance of asphalt substrates, but its shortcomings are also obvious: poor self-healing performance and creep performance. The deformation of the base surface of the building is likely to cause cracking of the waterproof layer, so the original performance of the waterproof material cannot be maintained, which greatly limits the service life

Abstract

The invention discloses a liquid ethylene propylene diene monomer rubber asphalt waterproofing paint and a preparation method thereof. The used additives are long-chain low-molecular-weight additives, can enable the asphalt to be mixed and dissolved with various high-polymer materials to form a stable combination in the production process, and display the respective characteristics in the most stable state in the application process, thereby achieving the goal of never curing. The preparation method comprises the following steps: heating asphalt according to the formula weight to 130-180 DEG C, adding liquid ethylene propylene diene monomer rubber, SBS (styrene-butadiene-styrene), naphthenic oil and a petroleum resin into the asphalt according to the formula weight, stirring at 175-180 DEG C for 1-2 hours, cooling to 160 DEG C, adding regenerated rubber powder according to the formula weight, uniformly stirring for 1-1.5 hours to the granule-free molten state, and discharging. The liquid ethylene propylene diene monomer rubber asphalt waterproofing paint has favorable self-recovery property and creep property, and can effectively solve the problem of waterproofing layer cracking caused by deformation of the building basal plane.

Description

technical field [0001] The invention relates to a liquid EPDM asphalt waterproof coating and a preparation method thereof. Background technique [0002] The waterproof materials in the prior art include modified asphalt waterproof coatings. The use of various polymer modified asphalt can greatly improve the performance of asphalt substrates, but its shortcomings are also obvious: poor self-healing performance and creep performance. The deformation of the base surface of the building is likely to cause cracking of the waterproof layer, so the original performance of the waterproof material cannot be maintained, which greatly limits the service life. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide a kind of liquid ternary vinyl rubber asphalt waterproof coating and preparation method thereof, the additive used in it is long chain, low molecular weight, can make asphalt and various macromolecule The materials are in...
