Problems solved by technology

[0009] However, the particle size of the spraying raw material powder is a very important factor affecting the coating level of plasma arc spraying. When the particle size of the powder particles is too small, the powder is easy to block the spraying pipeline during the transmission process, making it difficult to spray. When the particle size of the powder is too large, the powder will not be completely heated in the jet, and cannot be completely melted, and the quality of the coating will be poor

Embodiment 1

[0082] The present invention proposes a resin matrix ceramic spraying method with high hardness, high wear resistance and high safety, such as Figure 6 As shown, the main steps are as follows:

[0083] (1) Preparation of resin matrix:

[0084] The selection of the substrate should choose a wide range of material sources and cost-effective resin materials with low cutting difficulty and high strength. If necessary, materials that can still maintain certain plasticity, wear resistance and toughness after high temperature and high heat treatment should be selected. .

[0085] (2) Pretreatment of the resin matrix: sandblasting or frosting:

[0086] In order to allow the ceramic coating raw material and the substrate to be more closely combined, it is necessary to perform sandblasting or frosting on the resin substrate. This step greatly increases the roughness of the substrate surface. During plasma arc spraying, the ceramic material powder particles melted or melted by plasm...

Embodiment 2

[0111] A method for spraying resin matrix ceramics, comprising the steps of:

[0112] (1) Select the resin matrix:

[0113] Determine the resin matrix for zirconia liquid ceramic spraying. The selection of the resin matrix is ​​from a wide range of sources, the cost is suitable, and the resin material with low cutting difficulty and high strength should be selected. If necessary, it should still be able to maintain a certain Excellent plasticity, wear resistance and toughness of the resin material.

[0114] (2) Pretreatment of the resin matrix: sandblasting (frosting) treatment.

[0115] Described blasting treatment refers to:

[0116] Use compressed air to beat the sand particles to the surface of the resin matrix in a sandblasting machine, and the pressure of the compressed air is about 0.7MPa. When sandblasting is used to treat the surface of the resin matrix, the nozzle of the spray gun forms a 45-degree angle with the resin matrix, and moves at a constant speed from on...

Embodiment 3

[0134] All the steps are the same as in Example 1 or Example 2, the difference is that the zirconia raw material powder is obtained by the following steps:

[0135] Dissolve quantitative urea and zirconium nitrate in deionized water to prepare a zirconium nitrate mixture; add 1 part of Span-80 to a container containing 10 parts of xylene, and use electric stirring during the addition of Span-80 Stir the xylene mixed solution in the container, and when the xylene mixed solution in the container becomes uniform, add 1 part of the prepared zirconium nitrate mixed solution to the container, and obtain a white emulsion after emulsification for half an hour. Pour the emulsion into the reaction kettle, seal the reaction kettle and put it in an oven at 120 degrees Celsius for reaction. After 15 hours of reaction, take out the reaction kettle and wait for it to cool to room temperature, then open the reaction kettle to take samples to obtain white crystals; white crystals After filteri...

Abstract

The invention belongs to the technical field of building matrix coating treatment, and concretely relates to a resin matrix ceramic spraying method in architecture. The method includes the following steps: (1.1) preparing a resin matrix; (1.2) carrying out sandblasting or sanding pretreatment on the resin matrix; (1.3) preparing an alumina raw material powder; (1.4) heating calcined alumina nano-powder to achieve a molten state; and (1.5) spraying an alumina nano-liquid material. A traditional spraying technology is characterized in that nanoparticles are directly placed in a spray gun and areheated and sprayed, and a short heating process makes some particles, not completely melted in the melting process, sprayed on a matrix, so the combining effect cannot meet enough strength demands and adhesion demands. The melting of the sintered powder into the molten state before feeding of the spray gun avoids above defects, and makes the strength, hardness, toughness and other comprehensive parameters of the ceramic coating obviously better than those achieved by ordinary spraying technologies.

Description

technical field [0001] The invention belongs to the technical field of building matrix coating treatment, and in particular relates to a method for spraying resin matrix ceramics in buildings. Background technique [0002] Energy-saving technology for wall insulation, closed decoration and decoration originated in Europe in the 1940s, and was first applied in Germany and Sweden. Because a large number of buildings in Germany were damaged during World War II, in order to repair the cracks in the outer walls, people pasted a layer of polystyrene or rock wool boards on the outer walls of the buildings to repair the cracks. Not long after, people discovered that this method not only can cover the cracks but also has many other advantages: thermal insulation, sound insulation, and moisture resistance are greatly improved, and the living comfort is also greatly improved. The United States has adopted external wall insulation and energy-saving technology for a relatively short per...
