Discoloration coating of ceramic tiles and production process thereof

Abstract

The invention relates to a ceramic tile allochromatic coating and the production technology thereof, the allochromatic coating comprises the following components by weight ratios: fluorocarbon resin 65 to 75, polarizing pigments 1 to 2, curing agents 12 to 16, diluents 12 to 16, antifoaming agents 0 to 1, levelling agents 0 to 1 and wetting and dispersing agents 0 to 1; wherein, the polarizing pigments are put in a small container and stirred after adding a few diluents; the fluorocarbon resin, the antifoaming agents, the levelling agents and the wetting and dispersing agents are put in a big container and stirred for 5 to 15 minutes; the polarizing pigments, the curing agents and the residual diluents are added into the big container and mixed and stirred to form homogenous solution; the adjusting viscosity is 20 to 30 seconds, the specific gravity is 0.5 to 1.5g / ml, and then the homogenous solution is filtered by a 75 to 85 mesh screen; the mixed solution is uniformly sprayed on glazed tiles by a spray gun, the quantity for spray is 130 to 170g per square meter, and then the sprayed glazed tiles are baked at the temperature of 70 to 90 DEG C for 50 to 70 minutes. The coating has the advantages of not affecting the strength of tiles, simple structure and production technology, low production cost, being easy to realize and uniform discoloration.

Description

A kind of ceramic tile discoloration coating and its production process technical field The invention relates to a ceramic tile production process, in particular to a ceramic tile discoloration coating and a production process thereof. Background technique Ceramic tile is an important building material, which is used to stick on the surface of buildings, such as exterior walls, interior walls, floors, etc., to protect buildings and promote aesthetics. With the improvement of people's requirements for the quality of life activities, the aesthetic value of ceramic tiles is much more important than its practical value. Chinese patent No. 95102188.5 discloses a "method for manufacturing color-changing ceramic decorative tiles". Different colors and glazes are applied to the surface, and the color-changing ceramic decorative tiles can be obtained after firing. This kind of tile mainly realizes the color-changing effect of the tile by seeing different sides of the "V"-shaped ...
