[0021] Embodiment 2: A kind of lost foam water-based coating for cast iron, it is characterized in that: it comprises the raw material of following mass percentage content: high alumina bauxite 19%, pearl powder 22%, brown corundum 15%, sodium bentonite 2.7% , polyacrylamide 1.8%, polyvinyl acetate emulsion 3.0%, maltodextrin 1.1%, silica sol 5.8%, sodium hexametaphosphate 0.4%, tributyl phosphate 0.45%, sodium pentachlorophenate 0.3%, OP-10 activity Agent 0.35%, water 28%.
Embodiment 3
[0022] Embodiment three: a kind of lost foam water-based paint for cast iron, it is characterized in that: it comprises the raw material of following mass percentage content: high alumina bauxite 24%, pearl powder 18%, brown corundum 15%, sodium bentonite 2.1% , polyacrylamide 2.0%, polyvinyl acetate emulsion 3.5%, maltodextrin 1.35%, silica sol 4.6%, sodium hexametaphosphate 0.85%, tributyl phosphate 0.3%, sodium pentachlorophenate 0.3%, OP-10 activity Agent 0.4%, water 27.6%.
[0023] The production method of above-mentioned a kind of lost foam water-based paint for cast iron comprises the steps:
[0024] a, bentonite pretreatment: under high-speed stirring, the sodium-based bentonite is mixed with water at a mass ratio of 1:4, completely dispersed evenly, and left to stand for 24 hours to obtain a pre-treated sodium-based bentonite slurry;
[0025] b. Pretreatment of polyacrylamide and maltodextrin: add sufficient amount of water to the mixing tank, and slowly add the poly...
