Embodiment Construction
[0009] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0010] The formula and production process of water-emulsion polymer modified asphalt waterproof coating consist of the following ingredients in mass percentage,
[0011]
[0012] First, modify the asphalt with a modifier and heat it to 180°C, mix the water and emulsifier and heat it to 80°C, and adjust the pH value to 1.5-2.5 with an acid; use the hot asphalt and the mixed emulsified water in proportion Emulsification mill for emulsification; then add attapulgite to stir, cool and fill.

The invention discloses a formula and a manufacturing process of water emulsion type high polymer modified asphalt waterproof paint. The formula is characterized by comprising the following components in percentage by mass: 40 to 45 percent of No.90 asphalt, 5 to 9 percent of modifier, 35 to 45 percent of water, 6 to 10 percent of emulsifier, 2 to 5 percent of attapulgite. The manufacturing process comprises: modifying the asphalt with the modifier, heating to 180 DEG C, mixing water and the emulsifier, heating the mixture to 80 DEG C, and regulating the pH value with acid to 1.5 to 2.5; emulsifying the hot asphalt and mixed emulsifier water in a special emulsification mill according to a ratio; and adding the attapulgite and filling. The invention has the advantages that: the water emulsion type high polymer modified asphalt waterproof paint can be used for civil and industrial building roof waterproofing projects, toilet and bathing room and kitchen waterproofing and seepage-proofing projects, basement, water pool and refrigeration house waterproofing and damp-proofing projects and the like and is an environment-friendly product without toxin, pollution and odor; and the coating film has high strength and toughness, water resistance, weather resistance, durability, high performance and the like.
Description
technical field [0001] The invention relates to a waterproof coating, in particular to a formula and a production process of a water-emulsion type high polymer modified asphalt waterproof coating. Background technique [0002] Building waterproof coating has the characteristics of simple construction and strong adaptability to complex structures, and is widely used in building construction. Waterproof coatings are mainly used for waterproofing, moisture-proofing and anti-seepage of some structural parts of buildings that may be eroded by water. Therefore, there are certain requirements for the high and low temperature resistance and anti-corrosion performance of waterproof coatings. Existing architectural waterproof coatings mainly include polyurethane waterproof coatings, polymer cement waterproof coatings, asphalt waterproof coatings and modified emulsified bitumen waterproof coatings, polymer bitumen waterproof coatings, silicone rubber waterproof coatings, etc. Among t...
