Problems solved by technology

[0005] Although there are some green body strengthening agents in the market at present, they will affect the mud performance and powder fluidity to varying degrees when used, resulting in pinholes and black spots, and even affect the molding of the green body. Therefore, it is urgent to study a product. Under the enhanced flexural strength of the green body, there is no adverse effect on the performance of the mud, and it has obvious effects on solving defects such as cracks and vulnerable corners of the green body, and can also increase the drying speed and firing speed of the green body in the kiln

Abstract

The invention relates to a modified bentonite ceramic body reinforcing agent, a manufacturing method and a use method thereof. The reinforcing agent comprises the following components by weight percent: 6-9% of polymerized hydroxy aluminum pillar bentonite, 2-4% of sodium carboxymethylcellulose and the balance of solvent; the modified bentonite ceramic body reinforcing agent being 100-mesh with the screen residue of 80-95% is prepared; and a calcium-based bentonite and a hydroxy aluminum pillar agent are heated and reacted in water, so as to form the polymerized hydroxy aluminum pillar bentonite. The manufacturing method comprises the following steps: preparing the hydroxy aluminum pillar agent; preparing the polymerized hydroxy aluminum pillar bentonite; and mixing 6-9% of polymerized hydroxy aluminum pillar bentonite, 2-4% of sodium carboxymethylcellulose and 87-92% of water, heating and stirring, thereby obtaining the reinforcing agent. According to the use method, before a ceramic blank is ball-milled and is to be discharged or after the ball-milling is finished, the modified bentonite ceramic body reinforcing agent which is 0.5-0.8% of the dry basis of the ceramic blank is added, and then the material is uniformly stirred. The modified bentonite ceramic body reinforcing agent can cause slurry and glaze to be higher in stability, excellent in mobility, low in viscosity and higher in quality.

Description

technical field [0001] The invention relates to a ceramic body reinforcing agent. In particular, it relates to a modified bentonite ceramic body reinforcing agent and its preparation method and application method. Background technique [0002] Among ceramic products, products with complex shape, large size and mass consume a lot of mineral resources and fuel energy. The thicker the wall, the greater the quality, the greater the consumption of raw materials and energy, and the higher the production cost. my country's ceramic industry has been developing at a double-digit growth rate for the past ten years. Ceramics have played an irreplaceable role in beautifying people's living environment and improving people's quality of life, but at the same time it has also caused a huge burden on energy and the environment. Based on the national production of sanitary ceramics in 2010, if the quality of existing products is reduced by 10%, more than 300,000 tons of high-quality raw mat...
