Low-temperature fast-fired low-clay glazed green brick and method for preparing same

Abstract

The invention provides a low-temperature fast-fired low-clay glazed green brick and a method for preparing the same. Locally resourceful raw mineral materials including Guangdong washed black mud, potassium and sodium stone powder, Xingning high-aluminum potassium sand, high-aluminum sand, wollastonite, permeable lime and Longtian sand are utilized, formulas and proportions for the raw materials are adjusted, and ball-milling iron removal, drying, compression molding and biscuit firing are carried out to obtain the low-temperature fast-fired low-clay glazed green brick. The low-temperature fast-fired low-clay glazed green brick and the method have the advantages that local abundant resources are sufficiently utilized in the aspect of raw material selection, accordingly, consumption of high-quality clay can be reduced, and the low-temperature fast-fired low-clay glazed green brick and the method are beneficial to protecting environments and cultivated lands; low-temperature fast firingis carried out, accordingly, the low-temperature fast-fired low-clay glazed green brick with high drying strength and flexural strength can be prepared by the aid of the method, only little processingwaste can be generated, and secondary firing can be facilitated after follow-up glazing to obtain high-quality glazed bricks.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a low-temperature fast-fired low-clay glazed brick body and a preparation method thereof. Background technique [0002] With the advancement of urbanization and new rural construction in the past ten years, the real estate industry has developed vigorously, and people's interior decoration grades have also been continuously improved. Glazed tiles have always been favored as a high-strength, easy-to-clean, and formaldehyde-free building decoration material. , and China has a long history and advanced technology in the development of ceramic materials, and now a large number of ceramic materials such as glazed tiles are exported abroad. [0003] In the production process of glazed tiles, clay is commonly used as its plastic raw material, and its addition amount is generally more than 20%. In order to produce high-quality glazed tiles and increase added value, high-qua...

Problems solved by technology

[0006] Chinese patent application document CN108069709A discloses a ceramic glazed tile based on artificial marble polishing slag, which uses feldspar as the main raw material, cooperates with artificial marble polishing slag and wollastonite, and uses 15-25% black slag as a plastic raw material to prepare Ceramic glazed tiles, but under the condition of adding auxiliary additives, the dry strength can only reach 100N / cm2, and the firing temperature of the green body is relatively high, which needs to be 1180-1200°C. It can be seen that the amount of black clay used in this application is relatively large. However, it still cannot meet the needs of low temperature, fast burning and high performance in the industry.

[0008] To sum up, in the process of using black enamel as raw material to prepare glazed brick bodies in the prior art, there are problems such as large amount of enamel, high bisque firing temperature, low drying strength of forming blanks, large loss, etc., and other constituent raw materials Large restrictions, not easy to mine nearby, not suitable for large-scale production, seriously affecting economic benefits
