Desert sand sintered product decoration glaze as well as preparation method and glazing methods thereof

Abstract

The invention provides a desert sand sintered product decoration glaze which is prepared by compounding a clinker, base auxiliary materials, a pigment and an adhesive in parts by weight. The invention also provides a preparation method of the glaze. The preparation method comprises the following steps: (1) preparing the clinker; (2) preparing the base auxiliary materials; (3) ball-milling the pigment; (4) mixing and ball-milling the clinker, the base auxiliary materials, the pigment and the adhesive to obtain slurry; and (5) passing the slurry through a water sieve, and adjusting the density to obtain the desert sand sintered product decoration glaze. In addition, the invention further provides four glazing methods of the glaze. According to the invention, the desert sand sintered product decoration glaze is easy and simple to operate, easy to control, and safe and reliable, is suitable for large-scale industrialized production, overcomes the shortcoming that the traditional glaze is not matched with a desert sand sintered product, opens up a new way for a low-temperature leadless glaze for the desert sand sintered product and a glazing process of the low-temperature leadless glaze, and has wide popularization value and significant energy-saving effect.

Description

Technical field [0001] The invention belongs to the technical field of ceramic materials, and specifically relates to a decorative glaze for a desert sand sintered product, a preparation method and a glazing method. Background technique [0002] Deserts and land desertification are serious problems currently facing our country. According to statistics from relevant parties, the area of ​​deserts and desertification areas that have naturally formed in the history of our inland has reached 1,739,700 square kilometers, accounting for more than 18% of the country's land area. In order to prevent the further expansion of desertification, it is urgent to transform and use the desert on the basis of the existing sand control and sand fixation, so that the desert sand can be recycled, creating unprecedented economic benefits, so as to realize the unification of ecological and economic benefits. Its significance Is huge. [0003] The desert sand is mainly composed of silica-based mineral c...

Problems solved by technology

First of all, it is necessary to overcome the contradiction and deficiency that the sintering temperature of desert sand sintered products is low in the sintering process, and the temperature of the existing ceramic glaze is relatively high, and the two cannot be sintered because of the difference in temperature; There are significant differences in the main components of the glaze and desert sand sintered products, resulting in a large disparity in the coefficient of thermal expansion between the two, a larger difference in expansion, and different thermal expansion and cold contraction with changes in temperature. Therefore, using the existing ceramic glaze After glazing by conventional methods, the glaze on the surface of desert sand sintered products is prone to defects such as peeling, rolling glaze, pinholes, orange peel, etc.

[0005] In summary, up to now, no reports have been found on the decorative glazes for desert sand sintered products and their preparation methods and glazing methods.
