Embodiment

[0006] Example: An improved method for preparing waterproof coatings. Select 15 parts of polystyrene foam, add 100 parts of coal tar, heat for 8 hours to dissolve the polystyrene foam, and cool down to 80 degrees after the coal tar is completely dehydrated. , add to 22.5 parts of toluene and stir to dissolve, add 20 parts of heavy calcium powder to it and stir evenly, dissolve 14 parts of styrene-butadiene rubber crushed into granules with 100 parts of xylene, take 21 parts of styrene-butadiene rubber and cut into pieces and pulverize into granules, Add it to the mixing tank, add 200 parts of toluene and stir to dissolve it all, mix with 200 parts of asphalt and stir for 7 hours, then add it and stir evenly.

Abstract

The present invention discloses a preparation method of waterproof dope; polystyrene foam plastic is selected to be added into coal tar for heating so as to be melted. After the coal tar are dehydrated completely, the temperature decreases, and the coal tar is added into toluol for milling and dissolving, and then heavy calcium powder is added to be milled evenly. Butylbenzene rubber is dissolved by dimethyl benzene. Butylbenzene rubber is cut into powder to grain, and then is added into a milling pot; toluol is added to be milled and dissolved; asphaltum is added to be matched with the toluol for milling so as to be milled evenly. Finally, the present invention can be obtained. The present invention has the advantages of long-term aging-resisting period, much better waterproof, heat-resisting, cool-resisting, windproof performance; the soft film is not easy to be broken; the present invention also has the advantages of heat-resisting, cool-resisting and can be used both indoor and outdoor; the plasticity is much better and the lighteness is much higher.

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 solution of the present invention is: an improved preparation method of waterproof paint, characterized in that: select 15 parts of polystyrene foam, add in 100 parts of coal tar, heat for 8 hours, dissolve polystyrene foam, 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 parts of heav...
