Problems solved by technology

[0004] The waterproof material disclosed in the above patents forms a three-dimensional network structure inside after forming a film, and still contains some hydrophilic groups inside. After soaking in water again, it is easy to soften and swell, and peel off from the substrate. This kind of waterproof material has poor durable waterproof performance.

Abstract

The invention relates to an emulsified asphalt waterproof coating and a preparation method thereof. The emulsified asphalt waterproof coating is prepared from the following components in parts by weight: 280 to 320 parts of pure acrylic emulsion, 380 to 420 parts of SBS (styrene-butadiene-styrene) modified asphalt, 8 to 12 parts of emulsifier, 3 to 8 parts of silane coupling agent, and 240 to 320parts of enhancer, wherein the enhancer is prepared from 130 to 180 parts of triple superphosphate, 70 to 80 parts of bentonite, and 40 to 60 parts of kaolin. The emulsified asphalt waterproof coatingwith the proportional ratio has the characteristics that the adhesion force is strong, the condensing is quick, and the filming is easy.

Description

technical field [0001] The invention relates to the field of water-oil composite waterproof paint, in particular to an emulsified asphalt waterproof paint and a preparation method thereof. Background technique [0002] After the building wall has been used for a long time, it is prone to cracking after a long period of wind and rain. Different types of waterproof materials can be used to reinforce the building wall. Commonly used waterproof coatings use vinyl acetate-ethylene copolymer emulsion or acrylic emulsion as the main body, and add filler materials or pigments to stir and mix. For example: the Chinese patent application publication number CN107117910A discloses a waterproof material for construction and its preparation method. strength or consistency. [0003] The Chinese patent with application publication number CN103540212A discloses a rigid-flexible compound penetrating crystalline waterproof coating, which mainly includes emulsion, inorganic silicate penetrati...
