Embodiment 1~ Embodiment 5
[0014] Prepare the following raw materials:
[0015] Waterborne epoxy resin (OudraSperse WB 6001, Dow Chemical)
[0016] Silica sol (PA30, Shandong Baite New Material Co., Ltd.)
[0017] Anti-corrosion pigments: zinc phosphate (Taicang Chengxin Chemical Co., Ltd.), modified zinc phosphate (MZP 409, Changsha Ruishi Environmental Protection New Material Co., Ltd.), zinc molybdate (Taizhou Xinyuan Chemical Co., Ltd.), aluminum tripolyphosphate (Weihai Tianchuang Fine Chemical Co., Ltd.), calcium ion exchange pigment (SHIELDEXAC5 ion exchange antirust pigment, Grace China Co., Ltd.).
[0018] Pigments and fillers: iron oxide red (Zibo Yanyong iron oxide red factory), titanium dioxide (R737, Shanghai Xujiang Industrial Co., Ltd.), barium sulfate (Shanghai Jianghu Titanium White Chemical Products Co., Ltd.), talcum powder (Jiangxi Shanggao County Xuefeng Powder Co., Ltd.), mica powder (Dongguan Ruiqi Chemical Co., Ltd.).
[0019] Auxiliaries: wetting agent (FLASH-X 330, Halox Com...
Embodiment 6~ Embodiment 10
[0035] As an improved scheme of the water-based anticorrosion paint provided by the present invention, the anticorrosion pigment also contains aluminum tripolyphosphate and / or calcium ion exchange pigment. The weight of the water-based epoxy resin is 1 to 9 times the weight of the silica sol, more preferably, the weight of the water-based epoxy resin is 3 to 5 times the weight of the silica sol.
[0036] Prepare each raw material, source of raw material is the same as embodiment 1~embodiment 5, the weight ratio of each raw material is shown in table 3. Among them, the weight ratios of water-based epoxy resin and silica sol are 1:1, 3:1, 4:1, 5:1, and 9:1, respectively.
[0037] The weight proportion of each component of the water-based anticorrosion coating in the embodiment 6~the embodiment 10 of table 5
[0038]
[0039]
[0040] The preparation method is the same as in Example 1 to Example 5.
