Abstract

The invention relates to a preparation method of a roof waterproof coating. Vinyl acetate monomer, weight percentage of which is 20-40 percent, is firstly put into a reactor, tar, weight percentage of which is 60-80 percent, is gradually added during stirring, stirring speed is raised until all rationed tar is added and pH value is adjusted by sodium hydroxide into alkaline, which results in base material; dispersant, toughening agent, antioxidant and repellent auxiliary are added in sequence and dissolved by water and cured in sun. The invention has the advantages of being convenient to transport and construct, fast curing, good elongation and waterproof property, low cost and having rubber properties.

Description

technical field

[0001] The invention relates to a preparation method of roof waterproof paint. Background technique

[0002] The existing asphalt, modified asphalt, and waterproof coatings made of waste rubber have poor high and low temperature elongation, poor waterproof performance, and difficult construction. Contents of the invention

[0003] The object of the present invention is to overcome above-mentioned defective, a kind of roof waterproof coating preparation method is provided.

[0004] The technical solution of the present invention is: a method for preparing roof waterproof coating, which is characterized in that: first inject 20-40% by weight vinyl acetate monomer into the reaction kettle, and gradually add 60-80% by weight to the stirring Finally, increase the stirring speed until the proportioned tar is added, and use sodium hydroxide to adjust the PH value to be alkaline. Ethylene release, curing in the sun.

[0005] The invention has the following advan...

Examples

Embodiment

[0006] Embodiment: a kind of preparation method of roofing waterproof paint, injecting weight percentage in reaction kettle is 20-40% vinyl acetate monomer first, and it is gradually added into the tar that weight percentage is 60-80% in its stirring, finally increases stirring speed to After adding the proportioned tar, use sodium hydroxide to adjust the PH value to be alkaline. This is used as the base material. Finally, dispersant, toughener, anti-aging agent, and water repellent are added in sequence, released with water, and cured in the sun.
