Description
Technical field
The present invention is mainly used in model casting industry, relates to equal mixture of shell surface layer coating and preparation method thereof.
Background technology
Model casting industry, shell is the prerequisite obtaining premium casting, and the investment precoat of shell is then crucial especially.
Traditional investment precoat adopts full zirconium English powder to make Main Refractory, the metal casting excellent surface quality of its technique cast, but it is large also to there is cost of manufacture, and resource is petered out, the defect that sand removal difficulty is large.
At present, the zirconium English powder overwhelming majority raw material needed for China's model casting all relies on from Australian import, and price constantly rises, and import channel is extremely not smooth, causes China's foundry enterprise to face great survival pressure.
In view of the foregoing, domestic foundry industry finds relative low price one after another, supply refractory material that is stable, Domestic Resources relative abundance replaces or part replaces zirconium English powder.
Current best bet is: the fused quartz powder abundant with Domestic Resources mixes with import zirconium English powder, then makes investment precoat with mixed powder, and technique makes shell routinely.Because the density difference of fused quartz powder and zirconium English powder is too large, so the investment precoat extremely unstable made, cause the casting quality of cast also unstable, quality requirement and the standard of full zirconium English powder craft cannot be reached, more cannot realize reducing production cost, alleviate the target of sand removal difficulty and refractory material production domesticization.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the not good defect of casting quality adopting the mixed powder of fused quartz powder and zirconium English powder to make the unstability of investment precoat, cast, the equal mixture of a kind of casting is proposed, join in the mixture of fused quartz powder and zirconium English powder and make investment precoat, this mixed powder technique meets or exceeds full zirconium English powder craft, and makes the reduction of casting cost, the reduction of sand removal difficulty.
In order to solve the problems of the technologies described above, the present invention proposes following technical proposal: the equal mixture of a kind of casting, it is made up of the following component according to weight parts: pure water 100 parts, polysilicate aluminum chloride 5-10 part, polyacrylamide 1-5 part, organobentonite 5-10 part, polyethylene glycol 1-5 part, fluorine carbon non-ionic surface active agent 1-2 part, APES 0.5-1%.
In order to solve the problems of the technologies described above, the present invention proposes following technical proposal: the preparation method of the equal mixture of described casting, it comprises the following steps:
Step 1: pure water is put into clean chemical reaction still, then heat to 50-60 DEG C, restart agitator, its rotating speed controls at 50-100R/min;
Step 2: slowly add polyacrylamide, polysilicate aluminum chloride, rotating speed controls in 50-100R/min situation, stirs 15-20 minute;
Step 3: continue to add organobentonite, polyethylene glycol, rotating speed is adjusted to 100-150R/min, stirs 30-40 minute;
Step 4: continue to add fluorine carbon non-ionic surface active agent, APES, rotating speed is adjusted to 50-100R/min, stirs 60-120 minute, then stops heating, and temperature is controlled at 20-30 DEG C;
Step 5: static 1-2 hour, carries out packing, and packing material must be vinyon material and have the pail pack of sealing function.
The present invention compares conventional method and has following effect: significantly decrease the dependence to zirconium English powder, reduce production cost, and flour mixed with adulterants coating is stablized, and the foundry goods of its shell made, cast reaches the quality requirement of full zirconium English powder craft completely.Add the collapsibility of arenaceous shell, alleviate the cleaning difficulty of the residual sand of cast(ing) surface.
