Summary of the invention
In view of this, resulting porcelain is not the object of the present invention is to provide a kind of baking-free enamel device and preparation method thereof
Only high temperature resistant, intensity are high, and will not generate any poisonous and harmful substance, environment protection health at high temperature.
The purpose of the present invention is what is be achieved through the following technical solutions: a kind of baking-free enamel device includes by weight
Following components: 5-10 parts of light powder, 70-80 parts of jade powder, 60-80 parts of calcium phosphate, 20-30 parts of acid fiber by polylactic, coupling agent
3-8 parts.
Further, the coupling agent is the mixture that silane, phosphate or silane and phosphate are 3:1 in mass ratio.
It further, by weight further include following components: 5-8 parts of silica flour.
In addition, the present invention also provides a kind of preparation methods of baking-free enamel device, comprising the following steps:
A, stock, mixing: it is spare by formula feeding described in claim 1-3 any one, it is then sufficiently stirred mixed
It closes；
B, baking: toasting the resulting mixture of a step using baking machine, and baking temperature is 90 DEG C of 60-, baking
Time is 30-60 minutes；
C, first pressing: pouring into mold for the mixture through step b, pressurizes to the raw material in mold, pressed temperature 150-
200 DEG C, pressure is 10-15Mpa, and clamp time is 2-4 minutes；
D, exhaust: mold is crack, it is vented 2-4 seconds；
E, cure under pressure: molding pressurization again after exhaust, pressed temperature is 180-220 DEG C, and pressure is 15-19Mpa, mould
Pressing the time is 2-4 minutes, up to product after die sinking.
Beneficial effects of the present invention:
1) baking-free enamel device of the invention, in the production process without firing, therefore energy conservation and environmental protection.
2) baking-free enamel device of the invention, will not generate the noxious materials such as melamine, environment protection health.
3) baking-free enamel device of the invention, intensity is high, is not easy to break into pieces, high temperature resistant, is not easy to burst at high temperature.
4) baking-free enamel device of the invention, for calcium phosphate as stabilizer, heat resistance and the heat that porcelain can be improved are steady
Qualitative energy.
5) baking-free enamel device of the invention, degradable, no pollution to the environment.
Other advantages, target and feature of the invention will be illustrated in the following description to a certain extent, and
And to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, Huo Zheke
To be instructed from the practice of the present invention.
