Abstract
The invention discloses a coating for resin sand casting. The coating is prepared from the following formula components in parts by weight: 100-150 parts of diatom ooze, 100-120 parts of calcium carbonate, 80-90 parts of titanium dioxide, 90-100 parts of feldspar powder, 20-30 parts of paraffin, 30-50 parts of glycerin, 25-28 parts of silicone oil, 8-12 parts of diethanol amine, 10-12 parts of methylbenzene, 8-10 parts of polypropylene resin, 5-8 parts of phenolic resin, 6-10 parts of benzenesulfonic acid sodium salt, 5-8 parts of baking soda, 5-10 parts of lauryl sodium sulfate and 550-600 parts of purified water. The coating is prepared from the formula components in a reasonable ratio, the formula components are fully ground and uniformly mixed, the prepared coating is good in adhesiveness, easy to apply and resistant to high temperature, and after being cooled, the coating is easy for casting stripping, does not adhere to sand and is high in surface smoothness.
Description
Technical field
The present invention relates to the technical field of coating, particularly relate to a kind of coating for resin bonded sand mould casting.
Background technology
At present, conventional resins sand plays stop buffer action as sand mold in the middle of foundry goods and casting mold, reaches Sand sticking-resistant object.In casting cycle, due to reasons such as poor adhesive force, low, the fire-resistant difference of intensity, gas forming amount are large, the resin playing solidification between the grains of sand is burnt decomposition, and the connection between sand grains is destroyed, and high-temperature liquid metal will penetrate in sand mold, causes scab.Burn after decomposing simultaneously and form a large amount of gas, keep cast(ing) surface and form gas hole defect, easily cause foundry goods to produce scab, sand holes, the defects such as pore, carbon slag.
Coating used in sand casting, Main Function plays shielding action, density fireproof coating can be formed in whose surfaces under cast temperature, also prevent the gas that in molding sand, thermal decomposition produces from entering molten metal, the foundry goods of any surface finish can be obtained, surface quality of continuous castings, opposing molten metal are washed away to sand mold, prevent foundry goods scab etc. from playing an important role.Constantly catch height along with what require surface quality of continuous castings, the application of coating seems more and more important.
It is excellent that novel resin sand coating need possess adhesive property, easily brushes, and prevents the defect such as scab, burning into sand during casting, obtains the foundry goods of any surface finish.But it is low that current resin sand coating generally has suspension, often stir during use otherwise be difficult to brushing evenly, after brushing, in drying course, coating also easily comes off, and cause foundry goods scab, surface quality of continuous castings is poor.
Summary of the invention
The object of the invention is the shortcoming in order to overcome above-mentioned prior art, there is provided a kind of coating for resin bonded sand mould casting, this coating being used for resin bonded sand mould casting, through rational proportion recipe ingredient, fully grinds, mix, the paint adhesion made is good, easily brushes, high temperature resistance, after cooling, be easy to foundry goods peel off, be not stained with sand, surface smoothness is high.
The technical solution adopted for the present invention to solve the technical problems is: a kind of coating for resin bonded sand mould casting, is made up of the composition of raw materials component of following mass percent: 100-150 part diatom ooze, 100-120 part calcium carbonate, 80-90 part titanium dioxide, 90-100 part feldspar powder, 20-30 part paraffin, 30-50 part glycerine, 25-28 part silicone oil, 8-12 part diethanol amine, 10-12 part toluene, 8-10 part acrylic resin, 5-8 part phenolic resins, 6-10 part benzene sulfonic acid sodium salt, 5-8 part sodium bicarbonate, 5-10 part lauryl sodium sulfate, 550-600 part pure water.
Further, 100 parts of diatom oozes, 100 parts of calcium carbonate, 80 parts of titanium dioxides, 90 parts of feldspar powders, 20 parts of paraffin, 30 parts of glycerine, 25 parts of silicone oil, 8 parts of diethanol amine, 10 parts of toluene, 8 parts of acrylic resins, 5 parts of phenolic resins, 6 parts of benzene sulfonic acid sodium salts, 5 parts of sodium bicarbonate, 5 parts of lauryl sodium sulfate, 550 parts of pure water are comprised.
Or, comprise 150 parts of diatom oozes, 120 parts of calcium carbonate, 90 parts of titanium dioxides, 100 parts of feldspar powders, 30 parts of paraffin, 50 parts of glycerine, 28 parts of silicone oil, 12 parts of diethanol amine, 12 parts of toluene, 10 parts of acrylic resins, 8 parts of phenolic resins, 10 parts of benzene sulfonic acid sodium salts, 8 parts of sodium bicarbonate, 10 parts of lauryl sodium sulfate, 600 parts of pure water.
In sum, the invention has the beneficial effects as follows: the coating for resin bonded sand mould casting of the present invention, through rational proportion recipe ingredient, fully grinds, mixes, the paint adhesion made is good, easily brushes, high temperature resistance, after cooling, be easy to foundry goods peel off, be not stained with sand, surface smoothness is high.
