Abstract
The present invention relates to a silicon and aluminum composition made by coal gangue. The major components of the present invention are a silicon oxide and an aluminum oxide, the total amount of which can reach 96 to 99% (weight), and the ratio of SiO2 to Al2O3 is 1.09 to 1.30: 1. Coal gangue is ground into a proper granularity and baked at a temperature of 600 to 850DEG C for one to two hours to form the silicon and aluminum composition. The present invention can be used as an additive for rubber, plastics, etc., or used as a raw material in the industries of ceramics, building materials, coatings, molecular sieves, papermaking, etc., or used for separating and purifying chemical substances. The present invention has the advantages of simple production process and convenient operation, and has great social benefits and economic benefits for large scale production.
Description
The present invention relates to a kind of silicon aluminium composition (can be referred to as aluminum silicon powder again) and method for making and the purposes that make by coal gangue.
Coal gangue is to coexist and the bigger a kind of dark minerals of quantity with the coal seam in the colliery, China certain areas, and wherein some main component is a kaolinite, and the compound and the water of a certain amount of carbon and a small amount of sulphur and other elements are arranged.Do not see the relevant with it reported in literature that practical use is arranged, real is a kind of refuse, becomes the significant burden in the coal production, is badly in need of solving.
The objective of the invention is so that turn waste into wealth, to solve the practical problems, increase social benefit and economic benefit for described coal gangue provides a kind of feasible application approach.
The present invention includes:
(1) a kind of silicon aluminium composition of making by coal gangue.Said composition is of many uses, economic benefit is high, and major ingredient is the oxide compound of silicon and aluminium, and the total amount of the two can be up to 96-99%(weight), remaining is the elements such as Na, K, Mg, Ca, Ti, Fe, P or the oxide compound of a part of element wherein, SiO
2/ Al
2O
3Be 1.09-1.30.Said composition shows that in the electron microscope visual field it mainly is the mixture that has the Si oxide of tetrahedron sheet structure and contain the amorphous aluminum oxide of free key.
(2) said composition can be used as additive and is added in rubber, the plastic or other material and aftershaping by suitable proportion, also can be used as one of industrial raw material such as pottery, building materials, coating, molecular sieve, papermaking or raw material, in addition, aspect the separation of chemical substance, the purification good application prospects is being arranged also.
(3) prepare described method for compositions by coal gangue, this method comprises: colliery powder is broken into approximate to the desired granularity of product, 100-350 order for example, then in calciner, for example can select stoving oven or roasting kiln etc. for use, roasting 1-2 hour, maturing temperature can be according to the granularity of raw material, the amounts of weight and contained different compounds etc. are generally selected suitable temperature or temperature range in 600-850 ℃ of temperature range.After the roasting slowly cooling promptly get colorless product, its quality can be with conventional chemical analysis method mensuration.
For clearer explanation the present invention, enumerate following examples, but described example there is not any restriction to scope of the present invention.
Embodiment 1
With one liter of 250-350 purpose coal gangue in stoving oven in 750-800 ℃ of roasting 1 hour, after the cooling colourless powder-like product.Through chemical analysis, the silicon of said composition, aluminum oxide total amount are 99%, SiO
2/ Al
2O
3Be 1.17.
Embodiment 2
With the product of embodiment 1 as additive, with 10%(weight) amount be added in the polyethylene, be shaped to the wire insulation crust according to a conventional method, its resistance can be up to 7.85 * 10
13Ω cm.Not adding above-mentioned additive person resistance is 5.49 * 10
12Ω cm.
Claims (5)
