Environment-friendly ceramic material and preparation method thereof

Abstract

The invention discloses a ceramic material including the ingredients in percentages by weight as follows: 250%-60% of SiO, 10%-20% of Al2O3, 1%-10% of Fe2O3, 1%-3% of TiO20, 13%-20% of CaO, 0.5%-5% of MgO, 0.5%-5% of K2O, and 0.5%-5% of Na2O. The preparation steps includes (a) firstly making molds for production from sculptured prototypes by using sand silica gel, wherein the molds are silica gelsoft molds and a mold groove made of gypsum is arranged at the lower surface of each soft mold and fixedly provided with a silica gel mold internally; (b) pouring the ingredients into a bucket, adding appropriate amount of water, stirring to be uniform by a beater, pouring the slurry into four molds respectively for only one third, moving the molds into a vacuumizer for vacuumizing for 30 seconds, then moving the molds back to a working table, and pouring the left slurry into the molds for left two thirds to full; (2) pressing and embedding a prepared back plate into the slurry, scraping the surplus slurry to be flat with a scraper, solidifying for 20-30 minutes, and then demolding; (d) fully grinding the convex surplus slurry at the back part of the product to be flat, wherein the bottomgrinding time is within 4 hours; (e) filling pores which are caused by the reason that part of air bubbles of the product formed by slip casting of atomic putty are not discharged completely, finishing particles or mold lines on the surface of a green body to be smooth and drying for 16-48 hours naturally; (f) spraying paint or adhering pattern paper on the product and then drawing at drawing parts, and (g) packaging after product inspection. The environment-friendly ceramic material has the advantages of strong adaptability to environment, degradability, and no folds in shape.

Description

technical field [0001] The invention relates to a ceramic material, in particular to a degradable and environment-friendly ceramic material, and also relates to a preparation method of the ceramic material. Background technique [0002] Ceramic material is a shaped sintered body obtained by high temperature sintering. Its advantages are good corrosion resistance, high strength and beautiful appearance. However, the energy consumption in the process of ceramic products is high, and it is difficult to dispose of after disposal. Therefore, there are degradable green ceramics on the market. Environmentally friendly ceramic products have the advantages of wide sources of raw materials, low price, low sintering temperature, and high product qualification rate. Chinese patent 201010188756.5 discloses a degradable green environmental protection ceramic product. Its components are clay, quartz, diopside, and limestone mixed in a certain proportion. After ball milling and granulation,...
