Abstract

The present invention discloses a preparation method of waterproof dope; anhydrous coal tar and anhydrous hydroxybenzene oil are added into a kettle for heating; after being milled, PVC powder, dioctyl phthalate and stearic acid barium are added to be milled and heated; and then talcum powder is added into for heat-preservation; then stopping heating to cool and stopping mixing, the present invention can be obtained. The present invention has the advantages of weather resisting property, elasticity, extending performance, cohesiveness; when being low temperature, the coating film will not crack and chap; and when being high temperature, the coating film will not flow; the present invention also has the advantages of non-pollution and much better waterproof effect.

Description

technical field [0001] The invention relates to a preparation method of waterproof paint. Background technique [0002] At present, the method of coating petroleum asphalt with asphalt paper for waterproofing and seepage of buildings has gradually been eliminated due to poor effect, while the cost of new waterproof coiled materials is high and it is not easy to popularize; rubber modified petroleum asphalt waterproof coating has poor bonding strength and low temperature Coating cracks. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned defective, a kind of waterproof coating preparation method is provided. [0004] The technical solution of the present invention is: a preparation method of waterproof coating, which is characterized in that: 26% anhydrous coal tar and 21% anhydrous phenol oil are put into the heating kettle, and after stirring, 2.0% polyvinyl chloride powder, 0.8 % dioctyl phthalate, 0.2% barium stearate,...
