Abstract

The invention relates to a preparation method of a ceramic blank enhancer with decondensation effect on slurry and an application method of a product thereof. The preparation method comprises the following steps of using polysaccharide raw materials, powdery sodium hydroxide, halloysite clay, sodium phosphate, N-hydroxymethyl acrylamide, N,N-methylene bisacrylamide, persulfate and polysaccharide glue as raw materials, stirring, radiating by microwaves, curing by an ultraviolet lamp, heating, crushing, roasting, and cooling, so as to obtain the ceramic blank enhancer product; mixing 0.1 to 0.3 part of ceramic blank enhancer and 100 parts of ceramic blank raw material, so as to improve the anti-fracture strength of the ceramic blank by 20 to 200%. The ceramic blank enhancer has the advantages that the ceramic blank enhancer is applied to the fields of wet and dry-type ceramic preparation; by adopting the preparation method, the drainage of wastewater, waste slag and waste gas is avoided, and the danger to environment is very small, so that the market prospect is broad.

Description

technical field [0001] The invention belongs to the technical fields of ceramic industry and fine chemical industry, and in particular relates to a preparation method of a ceramic green body reinforcing agent having a decondensing effect on slurry and an application method of the product. Background technique [0002] In the production process of ceramics, cracks often occur in the forming, conveying, drying and glazing processes due to insufficient green body strength (Huo Xiuqiong. Development of a new type of green body reinforcement [J]. Ceramics, 2006(12): 23-25 .). To solve this problem, one way is to add high plasticity clay to ceramic raw materials. As a non-renewable resource, highly plastic clay has less and less mineral reserves, and usually has a high content of iron-titanium coloring ions. After adding it, it may affect the appearance quality of ceramic products (Cao Wen, Xia Guanghua, Tan Xunyan, etc. Compound denaturation Dry preparation of starch and its st...
