Abstract

A solvent waterproof coating capable of volatilizing to form film has a formulation of the following weight percentages: 30 percent of 60 number petroleum asphalt, 12 percent of chlorosulfonated polyethylene, 0.5 percent of phenolic resin, 1.5 percent of hydrogenated castor oil, 4.5 percent of tribasic aluminum maleate, 0.5 percent of triethylene tetramine, 25 percent of precipitated barium sulfate, 10 percent of talcum powder, 15.7 percent of xylene and 0.3 percent of butanol. The petroleum asphalt is added into a reaction kettle and heated to 200-220 DEG C for dehydration. When the temperature is decreased to 120-110 DEG C, xylene and butanol solvent are added and stirred, and then the chlorosulfonated polyethylene is added and stirred to be dissolved. In the temperature of 110 DEG C, hydrogenated castor oil, phenolic resin, tribasic aluminum maleate and triethylene tetramine are added and stirred to be dissolved. In the temperature of 110 DEG C, precipitated barium sulfate and talcum powder are added, stirred uniformly, discharged and packed. The invention has the advantages of high solid content, fast operating speed, suitability for scraping and coating and good application effect.

Description

technical field

[0001] The invention relates to a solvent-based waterproof coating capable of volatilization and film formation. Background technique

[0002] Existing waterproof coatings, the reactive type is too expensive, which restricts its wide application. The solvent-based and water-emulsion waterproof coatings have low solid content, and the film is thinner after one application. It takes multiple applications to reach the required thickness. It affects the construction progress and increases the difficulty. Contents of the invention

[0003] The object of the present invention is to overcome the above-mentioned defects and provide a solvent-based waterproof coating capable of volatilization and film formation.

[0004] The technical solution of the present invention is: a solvent-based waterproof coating that can be volatilized and formed into a film, characterized in that: petroleum asphalt is used as the base material, chlorosulfonated polyethylene is used as t...
