preparation example Construction

[0025] A preparation method of non-fired glaze, comprising the following steps:

[0026] (1) Mix and stir fly ash, silane coupling agent and water evenly, dry and grind to obtain modified fly ash;

[0027] (2) Mix Portland cement, quartz powder, quartz sand and corundum sand evenly to obtain mixture A;

[0028] (3) Mix and stir the nano-alumina sol and water evenly to obtain a mixture B;

[0029] (4) The modified fly ash, mixture A and mixture B are mixed and ball milled to prepare an unfired glaze.

[0030] In the present invention, the fly ash is modified by using the silane coupling agent. In the glass body of the modified fly ash modified by the silane coupling agent, spherical glass microspheres are the main ones, and spherical glass beads are mainly spherical. The particles can play a lubricating role in the slurry, better fill the gaps between the raw materials in the slurry, increase the bulk density of the raw materials in the slurry, and modify the fly ash by using...

Abstract

The invention discloses a preparation method of an unfired glaze, an unfired glaze and an inorganic base material. A preparation method of an unfired glaze comprises the following steps: (1) mixing and stirring fly ash, a silane coupling agent and water Uniform, dry and grind to obtain modified fly ash; (2) Mix Portland cement, quartz powder, quartz sand and corundum sand evenly to obtain mixture A; (3) Mix and stir nano-alumina sol and water evenly, Obtain mixture B; (4) Mix and ball-mill the modified fly ash, mixture A and mixture B to prepare an unfired glaze. The preparation method of the non-fired glaze is simple, and the prepared non-fired glaze has high coating hardness, good gloss, and good corrosion resistance, is environmentally friendly and effectively reduces costs, and has protective and decorative effects on inorganic substrates. The non-fired glaze can be directly coated on the surface of the inorganic substrate without sintering and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of inorganic non-metallic materials, in particular to a preparation method of an unfired glaze, an unfired glaze and an inorganic base material. Background technique [0002] With the rapid development of my country's real estate industry and decoration industry, the market demand for architectural decorative panels continues to grow. The architectural decorative panel industry is in a period of rapid development. At present, in the surface coating of inorganic substrates, paint is usually used for inorganic substrates The surface coating of organic coatings plays the role of decoration and protection, while organic coatings have poor corrosion resistance, poor hardness, and cumbersome processes, such as the need to use primers, which cannot even meet the standards for wall construction applications. In addition, organic coatings VOC emissions are too large, and organic coatings are not environmentally friendl...
