preparation example Construction

[0035] The present application embodiment also provides a method of preparing a coating comprising: mixing the material to water, and then mixed with an adhesive.

[0036] The main material can be mixed with water to make the components to disperse in water, and then mix with the adhesive can make each component even more even in the coating.

[0037] In some embodiments, the step of mixing the material and water comprises: mixing the material with a portion of the water into a paste, and then mixed with the remaining water.

[0038] This type can make the components in the main material more uniformly dispersed in water. Alternatively, a paste of water is 5 to 10 parts by mixing with the material.

[0039] When the suspension is included in the raw material, the material is mixed with water, and then mixed with the suspension, mixed with the adhesive.

[0040] Since the suspension is a solid, after mixing the material and water, the suspension can be mixed in water, and then mixe...

Embodiment 1

[0050] This embodiment provides a coating which is made of a raw material, wherein the raw material comprises 1 g of magnesium silicate aluminum, water glass 3g, deionized water 50g, and dissection. The main material is: 10 g of alumina powder, 3g of diatomite, 2g of glass powder, light calcium carbonate 3g and zinc oxide 2g.

[0051] The method of preparing the coating comprises mixing the material and mixed with a mixture of 8 g of water to form a paste, and then the remaining water was added to stir for 10 min, and the mixture was stirred with magnesium silicate, then the mixture was stirred for 5 min, Make paint.

Embodiment 2

[0053] This embodiment provides a coating and a preparation method thereof, and the preparation method is also the same as in Example 1. The coating material of the present embodiment differs only that the aluminum oxide powder of Example 1 will be replaced. Zirconium powder.

Abstract

The invention discloses a coating, a preparation method thereof and a method for spraying the coating on a metal mold cavity, and belongs to the technical field of coatings. The coating is prepared by mixing the following raw materials in parts by weight: 20-30 parts of a main material, 3-5 parts of an adhesive and 40-60 parts of water, the main material comprises refractory aggregate, glass powder, calcium carbonate and zinc oxide in a weight ratio of (10-14): (2-6): (3-6): (1-3). The coating has good high temperature resistance and can be firmly adhered to the surface of a cavity of a metal mold.

Description

Technical field [0001] The present application relates to the field of coating materials, and in particular, a method of spraying coating in a metal mold type cavity in a metal mold type cavity. Background technique [0002] Metal molds generally use coatings to prevent adhesion, making the castings to decline, reduce mechanical wear at high temperatures, and improve mold life. There are many kinds of coatings, but generally used in colored metals such as aluminum alloys, magnesium alloys, and for black metal extrusion casting, liquid metal temperatures, high temperature resistance to coatings. Current coatings used in metal extrusion casting are generally water-based gel graphite, which has a certain lubricity, but the adhesive properties of the coating have defects. Inventive content [0003] The present application provides a coating and a method thereof, a method of spraying the coating in a metal mold type chamber, which has a good high temperature resistance, and can be mo...
