Abstract
The utility model provides a preparation method for metal casting metallic paint, comprising procedures as follows: added with ten portion water, the 0.3 percent attapulqite clay is put into a colloid mill to be milled for two hours into solution A; then, added with the solution A and 3 percent soluble glass and 85.5 percent water, the mixture of 6 percent French chalk, 2 percent diatomite, 0.2 percent sodium dodecyl sulfonate and 3 boric acid are put into the colloid mill to be milled for two hours to obtain the metal casting coating, and then milling mixture 2 hours to prepare metal casting metallic paint. The invention has the advantages of good heat preservation, fire resistance, viscosity and paintability, and excellent suspension property resulting in that the coating is not susceptible to deposition in operation. The invention eliminates the heat cracking of the casting.
Description
Technical field
What the present invention relates to is a kind of method for preparing metal type casting coating material.
Background technology
Because liquid magnesium and the water in the oxygen in the atmosphere, nitrogen and the casting mold react, hole or oxidation elephant skin appear in cast(ing) surface, and foundry goods is scrapped when serious.Because the contraction of magnesium alloy is big, is prone to hot tearing in the casting process.The coating that current magnesium alloy production is used is used the coating of aluminium alloy mostly, and the magnesium foundry goods often produces decrepitation in the use.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of method for preparing metal type casting coating material is provided.
Technical scheme of the present invention is: a kind of method for preparing metal type casting coating material is characterized in that: composition quality percentage is: talcum powder 3-8%, diatomite 2-5%, waterglass 1.5-4%, attapulgite clay 0.3-2%, boric acid 2-7% and water 75-90%; Earlier suspending agent is mixed 10-30 part water in colloid mill milling 1-5 hour, makes first liquid, again talcum powder, diatomite and fire retardant are put into colloid mill, added first liquid, binding agent and water milling respectively 1-3 hour, get final product metal-type casting coating.
The present invention has the following advantages: have stronger heat insulating ability, anti-flammability, caking property and coating, have good suspension, be difficult for precipitation in the use.Reduce the hot cracking tendency of foundry goods.
The specific embodiment
Embodiment 1: a kind of method for preparing metal type casting coating material, attapulgite clay 0.3% is mixed 10 parts of water milling 2 hours in colloid mill, make first liquid, again talcum powder 6%, diatomite 2%, sodium alkyl sulfonate 0.2% and boric acid 3% are put into colloid mill, added first liquid, waterglass 3% and water 85.5% milling respectively 2 hours, get final product metal-type casting coating.
Embodiment 2: a kind of method for preparing metal type casting coating material, palygorskite clay 0.8% is mixed 20 parts of water milling 3 hours in colloid mill, and make first liquid, again with talcum powder 3%, diatomite 4%, NH4BF0.6%.Put into colloid mill with boric acid 3%, added first liquid, Ludox 4% and water 84.6% milling respectively 2 hours, get final product metal-type casting coating.
