Preparation method of ceramic glaze layer of foamed ceramic insulating veneer integral plate

Abstract

The invention discloses a preparation method of a ceramic glaze layer of a foamed ceramic insulating veneer integral plate, and belongs to the technical field of energy saving and environmental protection. The preparation method comprises the following steps: 1) cutting a foamed ceramic insulating thick plate prepared by high temperature foaming in a kiln into a foamed ceramic insulating single plate; 2) spraying and rolling a ceramic material of the veneer base layer on single surface of the foamed ceramic insulating single plate in the step 1), and baking at the temperature of 220-420 DEG Cto obtain a veneer base layer of the foamed ceramic insulating veneer integral plate, wherein the thickness of the veneer base layer is 1.2-1.8 mm; and 3) spraying or roll-coating the surface of the veneer base layer with a veneer glaze layer material, and baking at the temperature of 80-220 DEG C, wherein the thickness of the obtained ceramic glaze layer of the foamed ceramic insulating veneer integral plate is 30-60 [mu]m. The preparation method avoids the deformation of the ceramic insulating single plate, the adhesion force between the veneer and the foamed ceramic insulating substrate isincreased, the energy is saved and the production capacity is increased.

Description

technical field [0001] The invention relates to a method for preparing a thermal insulation material, which belongs to the technical field of energy conservation and environmental protection, and in particular to a method for preparing a ceramic glaze layer of a foamed ceramic thermal insulation and veneer integrated board. Background technique [0002] Inorganic fireproof insulation board is a kind of insulation board developed by using inorganic materials as raw materials. This inorganic material insulation board has the characteristics of safety and non-combustibility, energy saving and environmental protection, and high-efficiency sound insulation. It mainly includes foam concrete insulation board, perlite insulation board, rock wool insulation board, foam ceramic insulation board, foam glass insulation board, etc. With the improvement of people's living standards, the architectural field has higher and higher decorative requirements for facades, and a large number of v...

AI Technical Summary

Problems solved by technology

[0005] 1. The foamed ceramic insulation veneer is foamed into the kiln, resulting in low production capacity;

[0006] 2. The veneer is foamed and fired in the kiln, so the heat utilization rate is low and the energy waste is large;

[0007] 3. During the high-temperature foaming and firing process of the veneer blank, the plane size of the veneer is easily deformed and warped, and the yield rate is low

But the temperature of the second firing is still higher than 1000°C;

[0009] The second category: Paste organic material veneer on the foamed ceramic insulation substrate. The disadvantages of this pasted veneer preparation process:

[0010] 1. The weather resistance of the adhesive layer of the pasting process is poor. In the severe winter and hot outdoor conditions, the sun exposure and freezing and freezing will easily make the finish of the integrated board fall off, and the safety and reliability performance is poor.

[0011] 2. Poor fire resistance of organic material finishes or adhesives

[0012] In order to solve the problem of poor safety and reliability between the veneer and the substrate, a Chinese invention patent application (application publication number: CN106013657A, application publication date: 2016-10-12) discloses a method for making a foamed ceramic thermal insulation decorative board. Utilize the bonding effect of cement, stone and pigment frit to make the slurry, so that the decorative surface formed and the foamed ceramic insulation board are directly bonded together, one-time molding, no gap between the decorative panel and the insulation board Gap, close combination; but the facing materials such as cement used in the present invention are made of different materials from the foamed ceramic insulation board, and they are pasted at room temperature, so the adhesion between the facing material and the foamed ceramic insulation board is small, resulting in decorative The surface glaze layer has poor weather resistance and low strength
