Abstract

The present invention is a kind of artificial jade and its making method.The present invention is with raw materials such as extra large sand, lime, Feldspar Powders, refining material stove high temperature by two above differing tempss burns till and mixes in same homework department, make it produce distinct colors level and unmixing interface, send into copper mold compression moulding then, crystal is separated out and is grown in annealing again, and cooling back sanding and polishing becomes product.The present invention has once shaped, reduce energy consumption, advantage such as reduce cost.

Description

The artificial jade

The present invention relates to a kind of building decoration stone material, be specially adapted to a kind of with inorganic substance synthetic crystalline state artificial jade and preparation method thereof.

The building decoration stone material is divided into lithotome and synthetic stone material at present, and the tooling cost of lithotome such as natural granite is very high, and cutting polishing energy consumption is bigger, and facility investment is big, makes the product price be difficult to descend; Natural marble and marble, because corrosion resistance is poor, hardness is low, causes surface smoothness to be difficult to keep, and is not suitable for exterior wall or senior finishing.And the synthetic stone material mostly adopts resin bond to form, and as the disclosed a kind of building molding decorative material of russian patent SU-483-365, cost is higher, and production technique is complicated, and the production cycle is longer, non-refractory; Cause in the artificial agate material, though its surface smoothness is better, it is one deck of very thin surface, and the more steam bubble that can't get rid of is closed in the inside, and transparent texture and gradation sense are all relatively poor.

The invention reside in provides a kind of employing cheap raw material, once-forming, reduces cutting quantity, reduces energy consumption and production costs, and its purposes is wide, the artificial jade and the making method of material and better performances.

Artificial jade of the present invention adopts following composition of raw materials scope (weight %) to be:

SiO ₂Be 59～66%, Al ₂O ₃Be 6～9%,

B ₂O ₃Be 0.5～1.3%, CaO is 8～14%,

ZnO is 6～7.8%, and BaO is 4～5%,

Na ₂O.K ₂O is 5～6%, Sb ₂O ₃Be 0～0.5%,

The summation of each component is 100%.

Manufacture method of the present invention is:

1. raw material is sent into refining material stove more than two respectively, good material is put into operation to allow refining, mixes down at 1100 ℃.

2. above-mentioned compound being put into punching block about 900 ℃ is shaped.

3. above-mentioned shaping prod is kept annealing in 4 hours at 700 ℃, be warming up to 1000 ℃ again and kept 8 hours, allow it split out crystal and crystal is grown up, after annealing, product is cooled to below 200 ℃ with 5 ℃/minute and takes out again, is finished product behind the sanding and polishing.

Be further described below in conjunction with embodiments of the invention.

Embodiment 1:

A material: SiO ₂Be 66%, Al ₂O ₃Be 7.8%,

B ₂O ₃Be 1.1%, CaO is 7.8%,

ZnO is 7.2%, and BaO is 4.5%,

Na ₂O.K ₂O is 5.6%

B material: SiO ₂Be 62%, Al ₂O ₃Be 6.3%,

B ₂O ₃Be 0.53%, CaO is 13.8%,

ZnO is 6.3%, and BaO is 4.2%,

Na ₂O.K ₂O is 5.3%, Sb ₂O ₃Be 0.15%,

Add the metal oxide of using as color.

Above-mentioned A material is melted in 1500 ℃ of stoves, and the B material melts in 1380 ℃ of stoves, again two kinds of material is put into homework department, mixes down at 1100 ℃, and its compound is put into punching block and is shaped in the time of 900 ℃.Then shaping prod is kept annealing in 4 hours at 700 ℃, is warming up to 1000 ℃ again and kept 8 hours, allow it split out crystal and crystal is grown up, after annealing, again with product with 5 ℃/minute be cooled to below 200 ℃ take out, be finished product behind the sanding and polishing.

Embodiment 2:

The A material is identical with method for refining with embodiment 1 materials.

B material: SiO ₂Be 59%, Al ₂O ₃Be 6%,

B ₂O ₃Be 0.5%, CaO is 13%,

ZnO is 6%, and BaO is 4%,

Na ₂O.K ₂O is 5%, Sb ₂O ₃Be 0.5%,

Fl ₂O ₃Be 6%,

Add the metal oxide of using as color.

The B material is melted in 1350 ℃ of stoves, and the A material melts in 1500 ℃ of stoves, two kinds of material is put into homework department again and is mixed down in 1100 ℃.Later technical process is identical with embodiment 1.

Embodiment 3:

The A material is still identical with method for refining with enforcement 1 materials.

B material: SiO ₂Be 63%, Al ₂O ₃Be 6.3%,

B ₂O ₃Be 0.53%, CaO is 14%,

ZnO is 6.3%, and BaO is 4.2%,

Na ₂O.K ₂O is 5.3%,

Add the metal oxide of using as color.

Above-mentioned B material melts in 1400 ℃ of stoves, and the A material melts in 1500 ℃ of stoves, two kinds of material is put into homework department again and is mixed down in 1100 ℃, and later technical process is identical with embodiment 1.

The present invention compared with prior art has the minimizing energy consumption, reduces cost the advantages such as once-forming.
