A kind of surface glaze and preparation method thereof

Abstract

The invention discloses a surface glaze, which is characterized in that the component weight ratio of the surface glaze is: 90-96% of matte frit, 4-6% of air knife soil, and 0.08-0.2% of sodium carboxymethyl cellulose , 0.30-0.36% of industrial sodium tripolyphosphate, 0.20-0.26% of ceramic debonding agent; and 30-36% of water in the total proportion of the above-mentioned raw materials. The preparation process of the surface glaze is as follows: raw materials entering the factory for inspection—batching—ball milling—testing—iron removal and sieving—staleness—passing through a 250-mesh iron removal vibrating screen for use. The ball milling time is 7-10 hours, the specific gravity of the ball-milling glaze slurry is 1.4-1.9 g / cm 3 , and the fineness is 0.6-1.0 mm; the flow rate of the ball-milling glaze slurry is controlled to be above 55 s. The product of the invention has the advantages of transparency and smoothness, bright color, wide market prospect and the like.

Description

technical field [0001] The invention relates to the field of ceramic raw materials, and more specifically relates to a formula of a top glaze and a preparation process thereof. Background technique [0002] The rapid growth of social economy has driven the development of the construction industry, and ceramic building materials such as ceramic products are widely used in the market because of their high hardness, good wear resistance, high density, small shrinkage deformation, and good decorative effects. Glaze is a layer of enamel covering the surface or bottom glaze of the product in the manufacturing process of enamel or ceramic products, which can resist corrosion and increase the decorative effect of the product. At present, there are many types of surface glazes in production. For example, the porcelain pieces of the prior art have different requirements for the frit in the glazing procedure, and the performance of the glaze is different. The amount of glaze must have ...

Problems solved by technology

At present, there are many types of surface glazes in production. For example, the porcelain pieces of the prior art have different requirements for the frit in the glazing procedure, and the performance of the glaze is different. The amount of glaze must have a certain thickness, and the temperature and other performance controls Strict, products cannot be mixed firing, production scheduling is limited, production efficiency is low, traditional raw glaze has poor thermal stability, easy to produce color difference, easy to deform, small application range, high temperature viscosity, that is, Poor fluidity at high temperature, resulting in rough glaze, poor anti-fouling performance, low yield, etc. In addition, there is still room for further improvement in product transparency and smoothness
