Abstract

The invention relates to a high-efficiency ceramic body reinforcing agent composition and a product prepared by the high-efficiency ceramic body reinforcing agent composition. The high-efficiency ceramic body reinforcing agent composition comprises the following components in percentage by mass: 4% to 8% of acrylic pressure-sensitive adhesive emulsion, 1% to 3% of a modified natural polymer, 8% to15% of epoxy modified sodium polyacrylate and the balance of water. In the invention, the acrylic pressure-sensitive adhesive emulsion and the epoxy modified sodium polyacrylate are used in the fieldof a ceramic body reinforcing agent to play a high-efficiency reinforcing effect when a body is dried while the viscosity of body slurry is not affected, and test results show that the reinforcing agent can greatly shorten the cracking time and cracking length of a green body and has wide application prospects.

Description

technical field [0001] The invention relates to a ceramic body reinforcing agent, in particular to a high-efficiency ceramic body reinforcing agent composition and a product thereof, and belongs to the field of ceramic additives and ceramic production. technical background [0002] The ceramic industry is a "three-high industry" with high pollution, high energy consumption, and high resource consumption. With the rapid development of the ceramic industry, high-quality clay resources are becoming more and more scarce. Energy saving and emission reduction, and moderate thinning are the only way for the development of ceramics. road. The preparation of the billet is a very important link, and the dry strength of the billet is an important index, which has an important impact on the yield and quality of the product. In the current ceramic production, the phenomenon of low yield caused by insufficient green body strength is common. Appropriately thinned ceramic products have sig...
