Description
Technical field
The present invention relates to architectural pottery technical field more particularly to a kind of preparation works for the transmutation brick that transmutation effect is uniform
Skill.
Background technology
Usual utilization existing at present makes adobe surface form transmutation effect under the firing condition of certain reduction reaction
Adobe makes to form certain sootiness effect in adobe, realizes the decoration function after paving.Existing Ceramic Tiles element moulded pottery not yet put in a kiln to bake is typically
It is prepared by the raw material components of plastic mud material, clinker particles, chiltern raw material, flux and colorant, but during high-temperature firing,
Easily there is the heavy deformation of collapsing of adobe, or even vehicle collapse accident occurs in components fuse in raw material.It is existing in order to solve this problem,
Selection improves the intensity of green body by the way of increasing sandy content or the alumina content in blank raw material, or uses potassium sodium
Feldspar flux reduces the risk of the heavy deformation of collapsing of green body, but when chiltern in blank raw material and alumina content increase, among green body
Burn not yet done, final product quality is bad；The melt temperature scope of potassium albite flux is narrow, and technique controlling difficulty is big, and final product quality is still
Lowly, and because the uncontrollable of its firing process condition often also creates brick face to be susceptible to transmutation effect uneven, steady
Fixed situation, finally results in the problem of defect rate increases.
Invention content
It is an object of the invention to propose a kind of preparation process for the transmutation brick that transmutation effect is uniform, pass through charity color development glaze
The mode of slurry, solve because difficulty that firing condition controls is high be susceptible to part billet surface transmutation effect it is unstable
Problem, high yield rate.
For this purpose, the present invention uses following technical scheme：
A kind of preparation process for the transmutation brick that transmutation effect is uniform, in the surface charity color development glaze slip of Ceramic Tiles element moulded pottery not yet put in a kiln to bake,
And after dry tack free will be carried out with the green body of glaze pulp layer, finished product transmutation brick is obtained by firing；
The Ceramic Tiles element moulded pottery not yet put in a kiln to bake very compares according to quality, including the following raw material component：It is plastic mud material 50~60%, ripe
Expect particle 10~20%, chiltern raw material 10~15%, flux 5~15% and lithium feldspar 0.5~2%；
The color development glaze slip is according to mass percent, including the following raw material component：Raw ore pug 50~65%, mountain flour 4~
8%, fine sand 6~8%, soluble metallic salt 6~10%, color auxiliary 10~15% and excess water.
The present invention can not only effectively prevent the heavy of green body by being added to lithium feldspar in the raw material of Ceramic Tiles element moulded pottery not yet put in a kiln to bake
It collapses deformation, makes green body that there is better degree of sintering and flexural strength, and low using the fusing point of lithium feldspar, the high feature of boiling point,
Effectively melt temperature scope of the raw material of its Ceramic Tiles element moulded pottery not yet put in a kiln to bake in sintering procedure is widened so that burning process is easy to control
System.On this basis, by charity color development glaze slip, make to form glaze pulp layer in billet surface, and it can be dropped using lithium feldspar
The characteristics of firing temperature, after low-firing, soluble metallic salt forms more steady under the conditions of lower firing temperature
Fixed reduction keeps the colour developing of glaze more uniform, and transmutation is more uniform；And it is helped by being added to color development in glaze slip
Agent further promotes the color development at each position of green body glaze and more stablizes, is distinct, to make acquisition transmutation brick brick face
Transmutation color is more naturally, effectively prevent the prior art is susceptible to part green body because the difficulty that its firing condition controls is high
The transmutation effect on surface is unstable, the problem of causing defect rate to increase.
It further illustrates, the soluble metallic salt is one or more mixing of frerrous chloride, cobalt acetate and potassium chromate
The aqueous solution of formation.Using it is above-mentioned can color development soluble metallic salt, can be under the firing condition compared with low temperature, hair color effect is more
Add uniformly.
It further illustrates, the color auxiliary is the multivalent metal salt of the salicyclic acid derivatives replaced by phenylethylene.It is logical
It crosses and color auxiliary is used as using the multivalent metal salt of salicyclic acid derivatives, in the condition of low-firing, not only can effectively promote
Color developing effect into its soluble metallic salt is more uniform, and keeps color developing effect of glaze slip during firing more steady
It is fixed.
It further illustrating, the color development glaze slip further includes according to quality very than 1~3% nanometer penetration-assisting agent of meter,
The nanometer penetration-assisting agent is mixed by 35~55% ethylene glycol and 45~65% sodium carboxymethylcelluloses.In the color development glaze
Slurry can further promote the color development glaze slip to have better penetration property by being added to above-mentioned nanometer penetration-assisting agent, especially right
In the higher position of soluble metal salt content, downward osmotic effect is more, to be conducive to make the color development of whole glaze more
