Abstract
The invention discloses a preparation method of a high temperature resistant casting coating, relating to the technical field of casting. The method comprises the following steps: rolling and then mixing hollow ceramic powder, sodium silicate, bentonite, sepiolite and bauxite, adding the mixture to deionized water and stirring the mixture at a speed of 1800-2000rpm for 20-30 minutes; heating the mixed liquor to 40-60 DEG C, adding oxidants, a preservative, a wetting agent and a defoaming agent and stirring the materials at a speed of 400-600rpm for 20-30 minutes; after filtration, carrying out ultrasonic dispersion for 15-20 minutes, wherein the ultrasonic frequency is 80-100KHz. The problems that the existing metal mold casting coatings have poorer high temperature resistance and adhesion properties are solved by adopting the preparation method.
Description
Technical field
The present invention relates to casting technology field, especially a kind of preparation method of high temperature resistant cast paint.
Background technology
Permanent mold casting is poured in metal die by liquid metals, and to obtain a kind of casting method of foundry goods, it is also known as diecasting or permanent mold casting, is the technology grown up in recent years.The pouring temperature of metal mold and speed are all high than sand mold, fast, because will produce the defect such as underpriming, cold shut when pouring temperature is low, speed is slow.During permanent mold casting, all can apply coating at mold cavity surface, coating can be protected metal mold from thermal shock during cast, washes away and wear and tear, and can regulate the cooling velocity of foundry goods, improve the surface quality of foundry goods, when taking out foundry goods, can prevent casting mold from wearing and tearing.Resistance to elevated temperatures and the adhesion property of existing metal-type casting coating are poor, cannot meet the mass production requirement of heavy castings.
Summary of the invention
The object of this invention is to provide a kind of preparation method of high temperature resistant cast paint, it can solve existing metal-type casting coating resistance to elevated temperatures and the poor problem of adhesion property.
In order to solve the problem, the technical solution used in the present invention is: a kind of preparation method of high temperature resistant cast paint comprises the following steps:
A, feed proportioning by following mass fraction: hollow ceramic powder 45-60 part, waterglass 5-8 part, bentonite 2-4 part, sepiolite 2-3 part, bauxite 3-5 part, silica flour 1-2, oxidant 0.1-0.2, anticorrisive agent 0.01-0.05, wetting agent 0.05-0.2, defoamer 0.1-0.2, deionized water 50-60;
B, hollow ceramic powder, waterglass, bentonite, sepiolite and bauxite are rolled rear mixing, mixture is added in deionized water, stir 20-30 minute with 1800-2000 rev/min;
C, the mixed liquor of step B is heated to 40-60 DEG C, add oxidant, anticorrisive agent, wetting agent and defoamer and stir 20-30 minute, mixing speed is 400-600 rev/min;
After D, filtration, ultrasonic disperse 15-20 minute, supersonic frequency is 80-100KHz.
In the technical scheme of the preparation method of above-mentioned high temperature resistant cast paint, technical scheme can also be more specifically: 52 parts, hollow ceramic powder, waterglass 6 parts, bentonite 3 parts, sepiolite 3 parts, bauxite 4 parts, silica flour 1.5, oxidant 0.15, anticorrisive agent 0.02, wetting agent 0.1, defoamer 0.15, deionized water 55.
Further, the average grain diameter of hollow ceramic powder is 45-80um.
Further, oxidant be in chromium oxide and iron oxide one or both.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: obtained coating has excellent resistance to elevated temperatures, and tack is high, resistance to erosion, good air permeability, can meet the mass production of heavy castings, improves the surface quality of foundry goods; Coating is even, good stability, and being coated with property is good, and dope viscosity is about 40s, high temperature resistantly reaches more than 1750 DEG C, and heat insulation suppression efficiency reaches about 90%, coating abrasion performance more than 0.6.
