Abstract
A preparation method for manufacturing a building board by using tailing slag in mineral processing industry relates to a preparation method for a building board. Including tailing sediment, additive, its characterized in that: 48-70% of tailing slag and 30-52% of an additive by weight percent, uniformly stirring the materials, pouring the materials into a mold, performing compression molding in a vacuum forming machine, and curing at the constant temperature of 80 ℃ for 4 hours; the tailing slag is tailing slag of gold ore, copper ore, iron ore, lead-zinc ore and the like, and the additives are glue, a curing agent, an accelerant, a coupling agent, radiation-proof powder and modified nano aluminum hydroxide. Has the advantages that: the building board prepared by the invention can be suitable for indoor and outdoor decoration of civil building engineering of different grades, avoids the phenomenon of corrosion caused by mixed construction with reinforcing steel bars, and has the advantages of small board porosity, low water absorption rate, small deformation rate and practical value. The comprehensive utilization of mineral resources is really realized.
Description
Technical field:
The present invention relates to a kind of preparation method of building board, specifically is to utilize ore dressing industry mine tailings and addition material to make the preparation method of building board for raw material.
Background technology:
Reduce day by day and environmental protection cry day by day surging today in Mineral resources, the comprehensive utilization of mine tailing with reclaim the extremely attention of countries in the world.
The per capita rate of Mineral Resources in China is less than 20%, the total yield of Mineral resources only 30%, and along with the continuous expansion of mineral products range of application, its price constantly soaring, the increasing substantially of Mineral resources consumption, the quantity discharged of mine tailings increases thereupon year by year.
According to statistics, before 2000, the total tank farm stock of mine tailings is more than 5,000,000,000 ton, wherein, more than 2,600,000,000 ton of iron ore slag, more than 2.7 hundred million ton of gold tailings slag mainly contains more than 2,100,000,000 ton of non-ferrous metal mine tailings, 6.5 square kilometres of total floor spaces.After 2000, the stock of national mine tailings then increases progressively for more than 600,000,000 ton with the annual quantity discharged; Therefore, in the face of the mine tailings of continuous land occupation, for it seeks new application approach; Reach and return the original green of the earth, become the weighty responsibility of people in modern, simultaneously; Promote deepening continuously of practice, but do not tackled the comparatively rational solution of mine tailings all the time.
, describes application number in being patent one literary composition of people such as Wang Qi about " utilizing mine tailing residue to make the preparation method of building board " of 20101099175.1 Jinan City, Shandong Changqing District economic and technological development zone:
1, in mine tailings 30%～75%, additive 25%～75%, added the bittern greater than 25% weight part, pressed the bittern definition, minimal salt mixes and also reaches 3.5%; Through calculating, the CL ion content reaches 0.5309%, far surpassed require in the cement 0.06%; Therefore this sheet material will be avoided taking with reinforcing bar is mixed, otherwise meeting corrosion reinforcing bar, secondly; If have the incomplete bittern of chemical combination to exist, cause unavoidably and get damp.
2, with the moulding of squeezing mode, do not have through vacuum-treat, the sheet material porosity rises, and water-intake rate also rises, so that causes the decline of the permeable and mechanical property of sheet material.
3, its no constant temperature is handled, and causes the sheet material initial stage because the evaporation of moisture, and contraction unbalanced causes sheet deformation.
Summary of the invention:
The objective of the invention is to overcome above-mentioned defective, a kind of preparation method who utilizes ore dressing industry mine tailings to make building board is provided.
Scheme of the present invention is: comprise mine tailings, addition material, it is characterized in that: each raw material and weight percent are mine tailings 48～70%; Addition material 30～52% with the material stirring and evenly mixing, is poured mould into; Compression molding in vacuum forming machine, and under 80 ℃ of temperature, constant temperature solidified in 4 hours; Described mine tailings are mine tailings such as gold mine, copper mine, iron ore, plumbous zinc ore, and addition material is glue, solidifying agent, promotor, coupling agent, radioprotective powder, modified Nano white lake.
The invention has the advantages that: the prepared building board of the present invention is applicable to the indoor and outdoor decoration of different grades civil building engineering, avoids mixing with reinforcing bar and takes corrosion phenomena, and the sheet material porosity is little, and water-intake rate is low, and deformation rate is little, has practical value.Really realized the comprehensive utilization of Mineral resources.
Embodiment:
