CN103553554A - Artificial jade with high refractive index and manufacturing method thereof - Google Patents

Abstract

The invention belongs to the field of artwork and building decoration materials and in particular relates to an artificial jade which is prepared from inorganic chemical raw materials and has a high refractive index, and a preparation method of the artificial jade. The artificial jade is characterized by consisting of all or part of the following raw materials: lead oxide, quartz powder, aluminum oxide or aluminum hydroxide, zinc oxide, sodium carbonate, magnesium oxide, borax, sodium silicate, calcium oxide or calcium carbonate, titanium dioxide, potassium carbonate, talcum powder and paint. The preparation method comprises preparation steps of (1) weighing; (2) crushing and grinding; (3) mixing and stirring; (4) smelting; (5) carving and polishing. The artificial jade prepared by the method has high refractive index, and therefore, the surface of a product which is ground and polished can reflect more light rays, so that high brightness can be realized, and the appearance is attractive; furthermore, the artificial jade is fine and tough in quality and mild and soft in gloss; moreover, the raw materials are low in cost; a production technology is simple; the artificial jade has a wide application prospect.

Description

A kind of artificial jade and manufacture method thereof with high refractive index

Technical field

The invention belongs to artwork and building and ornament materials production field, is a kind of artificial jade and manufacture method thereof with high refractive index specifically.

Background technology

Beautiful quality exquisiteness is tough and tensile, color and luster is gentle soft, very popular since ancient times, yet the beautiful resource-constrained of natural output, can not meet the growing needs of people, so people adopt synthetic technology to manufacture jade material.

At present, on market, there is a large amount of artificial jade products, be widely used in jewellery, artwork, and in the production of building decoration series products, but these product majorities are that to take organism (unsaturated polyester) be main raw material, the aluminium hydroxide etc. of take is filler manufacture, because chemical constitution and microstructure and natural jade material are at a distance of all larger, therefore the performance of these products is also poor, as color, gloss, hardness, wear resistance, high temperature resistant, erosion resistance, weathering resistancies etc. are all poor, in use be vulnerable to many factors (mechanicalness, high temperature, corrosion, available light) effect and rotten or damage occurs.Another kind of artificial jade's product be in the market take cullet as main raw material, add some pigment raw materials simultaneously and carry out melting and form, but the chemical composition more complicated of cullet, the difficult quality of product is controlled and is unstable.

Chinese patent (the patent No.: the manufacture method that ZL2010101970986) proposes a kind of artificial jade, but the specific refractory power of the artificial jade that employing the method is manufactured is lower, after grinding and buffing, the brightness of product is lower, thereby affect the outward appearance of product, sales volume and price also can be adversely affected.

Summary of the invention

The object of the invention is, in order to overcome the weak point of currently available products, in the raw material of artificial jade, to add the composition with high refractive index, like this, artificial jade product is after grinding and buffing, surface can reflect more light, thereby has higher brightness, so outward appearance is more attractive.The present invention produces the artificial jade with premium properties with Inorganic Chemicals common on market, the outward appearance of product and internal performance and natural jade approach, it is characterized in that take that inorganic chemical product is as main raw material, add the component with high refractive index, through weighing, pulverizing, grinding, batch mixing, stirring, melting, polishing, glossing, prepared artificial jade.

Preparation method of the present invention is:

1. raw materials for production and proportioning:

Plumbous oxide: 5-45%

Silica powder: 25-85%

Aluminum oxide or aluminium hydroxide: 5-15%

Zinc oxide: 5-15%

Soda ash: 5-25%

Magnesium oxide: 5-15%

Borax: 10-30%

Water glass: 10-30%

Calcium oxide or calcium carbonate: 5-15%

Titanium dioxide: 1-5%

Salt of wormwood: 5-15%

Talcum powder: 0-10%

Pigment: 0.2-8%

Above-mentioned raw materials can be used also simultaneously and can partly use, according to the performance requriements of product and production cost are determined.

2. the preparation technology of artificial jade is:

(1) weigh on request various raw materials;

(2) by block raw material crushing, grinding;

(3) various raw materials are put into container and mix and stir, make material composition even;

(4) according to the shape of the product of design, manufacture gypsum mold, then pour the raw material mixing into gypsum mold, put into smelting furnace and carry out melting, be characterized as: raw material is put into gypsum mold, at room temperature pack smelting furnace into, with stove, heat up; Heating temperature is 800-1650 ℃, insulation 2-30 hour; Furnace cooling, in process of cooling, fire door is closed all the time;

(5) product is cooled to after room temperature, from stove, takes out;

(6) gypsum mold is removed, taken out artificial jade, then polish, polishing, obtain finished product.

     

Beneficial effect of the present invention:

The chemical constitution of artificial jade prepared in accordance with the present invention and microstructure and natural jade material approach, therefore performance and the natural jade material of artificial jade are also very approaching, quality exquisiteness is tough and tensile, gloss is gentle soft, and thering is high rigidity, high tenacity and good wear resistance, high thermal resistance, erosion resistance, weathering resistance etc., the decorate properties of product and mechanical property are all satisfactory.And, in the chemical composition of artificial jade, containing the plumbous oxide of certain content, the specific refractory power of plumbous oxide is higher, and like this, artificial jade product is after grinding and buffing, and surface can reflect more light, thereby has higher brightness, so outward appearance is more attractive.

Industrial chemicals composition that the present invention uses is accurate, fluctuating range is little, so the steady quality of artificial jade, easily controls.In addition, these raw materials are Chemicals common on market, cheap, and production cost is low.

Aspect preparation technology, preparation technology of the present invention is simple, lower to the requirement of equipment, and operator's technical ability is not had to particular requirement yet, and common laborer can operate.

Product of the present invention can be used for the fields such as artwork and building and ornament materials, has broad application prospects.
