Problems solved by technology

[0004] Some reinforcing agents currently on the market are mainly suitable for press-molded architectural ceramics, which have varying degrees of influence on the performance of mud, especially the fluidity of mud, so they are not suitable for grouting-molded sanitary ceramics
In addition, the general organic body enhancer is expensive, the amount of addition is small, it

Example Embodiment

[0014] A sanitary ceramic body strengthening agent, the components of which are calculated by mass percentage: 13-28% of water-soluble high molecular polymer binder, 46-68% of inorganic binder, and 18-28% of decoagulant.

[0015] The water-soluble polymer binder is sodium carboxymethyl cellulose (CMC).

[0016] The inorganic binder is bentonite.

[0017] The decoagulant is sodium pyrophosphate.

[0018] The manufacturing method of the sanitary ceramic body includes the steps of raw material weighing, ball milling, slurry preparation, grouting, demoulding and drying. In the ball milling step, 0.3-0.8% of the dry mass of the ceramic blank is added to the above-mentioned reinforcement To complete the preparation process.

[0019] See Table 1 for the chemical composition of the raw materials of the sanitary ceramics body.

Abstract

The invention discloses a ceramic body reinforcing agent and application thereof, and belongs to the ceramic building industry. The ceramic body reinforcing agent comprises the following components in percentage by mass: 13 to 28 percent of sodium carboxymethyl cellulose, 46 to 68 percent of inorganic adhesive bentonite, and 18 to 28 percent of deflocculating agent sodium pyrophosphate; the reinforcing agent is ball-milled together with ceramic blank and water so as to prepare slurry, then grouting for formation and demoulding for drying are performed, and a sanitary ceramic blank body is prepared. The ceramic body reinforcing agent is suitable for production technology of sanitary ceramics, the dry body strength can be enhanced greatly, the formation is easy, and the powder associativity is improved. The ceramic body reinforcing agent plays an excellent improving effect to preventing damage to the blank body on a conveyor line during vibration and drying processes caused by insufficient blank body strength. The ceramic body reinforcing agent has an obvious effect to overcome the defects of blank body and particle cracks, corner damage and the like.

Description

technical field [0001] The invention relates to a body reinforcing agent for sanitary ceramics, a preparation method and an application thereof, which are mainly applicable to the production process of sanitary ceramics and belong to the building ceramics industry. Background technique [0002] At present, the rapidly developing ceramic industry is still a "three-high industry" with high pollution, high energy consumption, and high resource consumption. The establishment of a technologically innovative energy-saving and emission-reducing green ceramic production model has far-reaching significance for the development of the ceramic industry. Thinning the ceramic body is an effective way to effectively reduce the consumption of raw materials, and at the same time can significantly reduce energy consumption, reduce waste emissions, reduce transportation costs, reduce building load-bearing, and improve product cost performance. Therefore, thinning ceramics and reducing productio...
