Preparation method of wood-grain brick with wood-knot effect

Abstract

The invention discloses a preparation method of a wood-grain brick with a wood-knot effect. The preparation method comprises the following steps: A, preparing materials: a1, preparing two or more clays which are consistent in drying rate and shrinkage rate, have a contrast effect in color after baked, and are 10 to 20 percent in water content; a2, preparing particle clusters containing non-uniformly-mixed pigments; B, feeding materials: putting raw materials, in proportion, into an extruder provided with spiral blades according to the required color contrast degree, putting the clay serving asbottom color first, putting the particle clusters intermittently after the clay is put into the extruder fully, putting the clay serving as grain, putting the particle clusters intermittently, then putting the clay serving as the bottom color, putting the particle clusters intermittently, putting the clay serving as grain, repeating the steps above and repeatedly, continuously and alternatively feeding; C, extruding and molding; D, performing drying and baking to obtain wood-grain bricks with wood-knot effect. By adopting the preparation method of the wood-grain brick with the wood-knot effect, the technical problem that an existing conventional extruding-molding wood-grain brick cannot have a wood-knot simulation effect is solved.

Description

technical field

[0001] The invention relates to the technical field of ceramic tiles, in particular to a preparation method of wood grain tiles with wood knot effect. Background technique

[0002] In the prior art, in order to obtain wood-grained bricks with a high degree of simulation, inkjet printing technology is generally used on brick adobes, and the wood knots are designed by inkjet printing. , will be subject to greater wear and tear, and the pattern will fade or be erased, while the existing wood-grained bricks with full-body wood-grained patterns are generally prepared by extrusion molding, but the extruded wood-grained bricks only have wood grains The effect of texture does not have the wood grain texture on real wood, so the overall simulation degree after paving is not high, and it is easy to find that it is a ceramic tile. In order to improve the simulation degree of extruded wood grain tiles, how to It is a technical problem that needs to be broken through in ...
