Abstract

The present invention provides a preparation method of improved waterproofing coating. Polystyrene foam is selected and added into coal tar. After being heated, the polystyrene foam is dissolved. After the coal tar is totally dehydrated, the temperature is lowered. The dehydrated coal tar is added into toluene, stirred and dissolved. Then heavy calcium powder is added; the product can be prepared after the mixture is further stirred uniformly. The present invention has the advantages of long anti-aging period, good water resistance, heat resistance, coldness resistance, and wind resistance; the soft conjunctival is not easy to be broken, of high-temperature and low-temperature resistance, and can be used indoors and outdoors; the coating has good tensile performances and high brightness.

Description

technical field [0001] The invention relates to an improved preparation method of waterproof paint. Background technique [0002] At present, waterproof materials for construction generally have a short anti-aging period, poor moisture resistance, water resistance, and wind resistance. They have a short service life on the outdoor top surface of buildings, can only be used indoors, and have high production costs. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned defective, a kind of improved waterproof coating preparation method is provided. [0004] The technical scheme of the present invention is: a kind of improved preparation method of waterproof coating, it is characterized in that: choose 15 parts of polystyrene foam, add in 100 parts of coal tar, heat 8 hours, make polystyrene foam dissolve, coal tar After all dehydration, cool down to 80 degrees, then add to 22.5 parts of toluene and stir to dissolve, then add 20...
