Abstract
The invention provides a preparation method for low viscosity casting resin sand core molding coating. Illite powder, sepiolite powder and bentonite are mixed together by the ratio of 1:0.5:0.5 to form 1.5 percent of suspending agent, which is mixed uniformly with 37 percent of water under low speed stirring, and then 1 percent of polyvinyl alcohol is added in the mixture; after dissolving polyvinyl alcohol, the mixture is added with 17 percent of zircon powder, 28 percent of brown corundum, 5 percent of porzite, 5.5 percent of flake graphite and 5 percent of forsterite, and then is stirred uniformly and continuously, at last, finished product is realized. The invention has the advantages of no pollution, low viscosity, no poison and rapid drying and can improve casting quality and productivity.
Description
Technical field
The present invention relates to a kind of method of producing low viscosity casting parts resin sand core casting paint.
Background technology
At present, the alcohol radical mold wash discharges poisonous, pernicious gas in the ignition dry run, the severe contamination air, and there is not hidden danger, the cost height, replaced by water base mold wash gradually, flow coat, the dip-coating coated technique of existing cast paint propose very high request to the coating process performance, flow coat, dip-coating paint viscosity are little, solid content is low, adopts existing brush coating prescription and it is difficult to satisfy flow coat, dip-coating paint in suspension, rheological characteristic, anti-stick grittiness requirement by simple viscosity adjustment.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of method of producing low viscosity casting parts resin sand core casting paint is provided.
Technical scheme of the present invention is: a kind of method of producing low viscosity casting parts resin sand core casting paint, it is characterized in that: will mix under stirring at low speed by 1.5% suspending agent of preparation in 1: 0.5: 0.5 and 37% water by Erie's stone flour, sepiolite powder and bentonite, add 1% polyvinyl alcohol, the dissolving back adds zirconium English powder 17%, brown corundum 28%, mullite 5%, crystalline flake graphite 5.5%, forsterite 5%, continue to stir, be finished product.
The present invention has the following advantages: pollution-free, low viscosity, nontoxic, fast dried, improve casting quality and production efficiency.
The specific embodiment
Embodiment: a kind of low viscosity casting parts resin sand core casting paint, to mix under stirring at low speed by 1.5% suspending agent of preparation in 1: 0.5: 0.5 and 37% water by Erie's stone flour, sepiolite powder and bentonite, add 1% polyvinyl alcohol, the dissolving back adds zirconium English powder 17%, brown corundum 28%, mullite 5%, crystalline flake graphite 5.5%, forsterite 5%, continue to stir, be finished product.
