Abstract
The invention provides a method for preparing a water-based natural rubber waterproofing coating. The coating comprises the following ingredients in part by weight: 50 to 65 parts of water-based natural rubber, 3 to 4.5 parts of ethanol butyl ether, 0.2 to 0.30 part of triethanolamine, 0.2 to 0.35 part of BX-12, 2.0 to 3.5 parts of ethylene glycol, 0.6 to 0.8 part of melamine, 10 to 13 parts of turpentine, 50 to 65 parts of styrene-acrylate emulsion and 10 to 13 parts of kaolin. The method comprises the following steps of: placing natural rubber into a stirrer; adding the ethanol butyl ether, the triethanolamine, the BX-12, the ethylene glycol, the melamine and the turpentine sequentially; uniformly stirring the mixture at normal temperature and normal pressure; and continuously adding the styrene-acrylate emulsion and the kaolin, and uniformly stirring the mixture to obtain the waterproofing coating. The strength of the coating is reinforced by adding 5 to 40-mesh quartz sand in a ratio of 1:1 into the coating during use. The selected ingredients are products sold in markets, and have 46 percent of solid content of the water-based natural rubber and 48 percent of solid content of the styrene-acrylate emulsion.
Description
technical field [0001] The invention relates to a waterproof paint, especially material selection and compounding. The product obtained through repeated practice and exploration has market competitiveness and practical value. Background technique [0002] According to literature search, Li Chengshun of Binzhou Liangyou Waterproof Material Co., Ltd. invented a production method of water-based two-component polyurethane waterproof coating (patent application number: 200610166219), which is made of polyether polyol, tartaric acid and isocyanate. Form A component; make B component with rubber oil, emulsifier, water, catalyst, solid filler, calcium hydroxide, and other additives. When in use, mix A and B components, which can be used for waterproofing construction of wet base. [0003] Zhonghong (Tianjin) Industrial Co., Ltd. Zhang Yunbo invented a single-component anti-sedimentation water-based waterproof coating production process (patent application number: 200610014958). Th...
