Light glazed ceramic tile with anion function and low water absorption and production method thereof

Abstract

The invention discloses a light glazed ceramic tile with anion function and low water absorption and a production method thereof. The formula of the glazed ceramic tile is as follows: fancy glaze containing 0.1-90 portions of stamp powder, 0.0-190 portions of pigments, 100-200 portions of stamp-pad ink and 0.01-15 portions of anion material; a green body containing 10-45 portions of ceramic shraff, 15-20 portions of clay, 10-20 portions of feldspar, 30-50 portions of sandstone, 30-50 portions of water, 0.0-0.3 portion of lignin, and 0.0-1.0 portion of sodium tripolyphosphate; and conventionalcover glaze. The production method comprises the following steps: stirring and screening the fancy glaze materials to obtain the fancy glaze; conducting ball-milling, screening and pelleting after materials of the green body are mixed, and then conducting compression moulding and drying, glazing, embossing, and sintering for 50-55 minutes at the temperature of 1195-1205 DEG C, thus obtaining the product. The ceramic tile has the characteristics of being light, low in water absorption, high in mechanical strength, small in coefficient of thermal conductivity, strong in antifouling capability and the like, can continuously release anions with the number of more than 500/cm3 in space, and can be widely applied to decoration of building outer walls and home furnishing spaces.

Description

technical field [0001] The invention belongs to the field of ceramic decoration materials, and in particular relates to a light-weight glazed ceramic brick with low water absorption and a preparation method thereof. Background technique [0002] With the rapid development of social economy and ceramic industry, especially in the past 20 years, the ceramic industry consumes more and more natural minerals, and ceramic waste is also increasing. According to incomplete statistics, in 2010, the national ceramic industry consumed more than 350 million tons of raw materials and produced more than 40 million tons of ceramic waste. The landfill and accumulation of ceramic waste occupy land, pollute the air and water quality, and the landfill of ceramic waste consumes a lot of manpower, material resources and financial resources. Such a large amount of ceramic waste is no longer a problem that can be solved simply by landfilling. How to turn waste into treasure and waste into resourc...

Problems solved by technology

[0005] So far, "a preparation method of anti-fouling and heat-insulating lightweight ceramic tiles" (CN 101781117A), "a light-weight heat-insulating ceramic material and its preparation method" (CN 101955370A), "a method of using ceramic waste to prepare The ceramic tiles prepared by patents such as "Method for foaming and non-deformable ceramics" (CN 101671160A) and "A porous ceramic material and its preparation method" (CN 101186519A) are high water absorption and unglazed. Although bricks have the characteristics of light weight, heat preservation and heat insulation, they do not have the health care function of releasing air negative ions

The product has a single function and the scope of use is quite narrow

And "a production method of healthy ceramic tiles that can release negative ions" (CN 1587186A), "ceramic material with negative ion emission function and its preparation method" (CN 1769242A), "negative ion ceramic products and its production method" (CN 101234899A) Patents related to negative ion ceramics such as "Manufacturing process of negative ion far-infrared multifunctional ceramic decorative floor and wall tiles" (CN 101328081A) indicate that the negative ion materials in the ceramic bricks prepared by the technology are directly added to the green body, and the addition is too much and the cost is high. Negative ion materials cause a lot of waste, and it does not involve the comprehensive utilization of ceramic waste and the research on light weight and heat insulation technology of products

The product has a single function and a narrow scope of use

Therefore, the prior art cannot solve the problem of using ceramic waste to prepare light weight, low water absorption glazed ceramic tiles with negative ion function.
