Description
Technical field
The present invention relates to building material field, specifically belong to a kind of foam battenboard preparation method containing vanadium ore deposit tailings.
Background technology
Vanadium is a kind of non-ferrous metal, and Vanadium Pentoxide in FLAKES extensively for industries such as metallurgy, chemical industry, is mainly used in smelting ferrovanadium. As alloy addition, account for more than the 80% of Vanadium Pentoxide in FLAKES total flow. Our vanadium ore resources is more, and total recoverable amount reserves 2,596 ten thousand tons, occupy third place in the world. Vanadium ore deposit is mainly originated among magma lithotype vanadium titano-magnetite bed, and as associated minerals output, vanadium ore deposit will produce a large amount of vanadium ore deposit tailings after exploiting.
For a long time, the comprehensive utilization of vanadium ore deposit tailings is a global problem always, although the comprehensive utilization of firefly vanadium ore deposit tailings having been carried out big quantifier elimination both at home and abroad, but due to various reasons in technology and economically, great majority are not put to industrial realization.
Glue powder polyphenyl particle, perlite particle are widely used just gradually, this lagging material site operation, because material is solid particulate, it is convenient to transport, in use using method is simple, has fire resistance excellent, the advantageous feature such as cost is lower, and it is pollution-free, but also have problems, that is, its material poor thermal insulation property, thermal insulation layer skin needs to smear cracking-resistant material, and thermal insulation layer
Can carrying out anticracking process after needing solidification dry after smearing, this just needs longer time of drying, therefore long construction period.
Summary of the invention
It is an object of the invention to provide a kind of foam battenboard preparation method containing vanadium ore deposit tailings, vanadium ore deposit tailings consumption is big, energy-conserving and environment-protective, alleviates useless vanadium ore deposit tailings and stores up the problem of environmental pollution processing and bringing, simultaneously for hollow brick provides new raw material sources.
The technical scheme of the present invention is as follows:
Containing a foam battenboard preparation method for vanadium ore deposit tailings, the method includes following step:
(1), by 10-12 part urethane foam, 23-30 part rubber grain feeding vapour pressure 0.3��0.4MPa, be preheating to 105��155 DEG C prefoaming machine in carry out pre-frothing, obtain the urethane foam of pre-frothing through 5��7h slaking;
(2) again 2-4 part vanadium ore deposit tailings is mixed according to the ratio of weight ratio 2: 1-3 with the urethane foam of pre-frothing so that vanadium ore deposit tailings is wrapped in the surface of the urethane foam of pre-frothing;
(3) after the urethane foam of step (2) and 4-6 part glass fibre, 10-12 part hot melt adhesive, 8-12 part rock wool hydrophober, 4-6 part Active gangue powder fully being stirred, put into shaping mould, 95��110 DEG C of steam heating are imported in mould, maintenance pressure is 0.08MPa��0.15Mpa, the demoulding;
(3) green compact sheet material carries out the steam press maintenance stage, comprises vacuum, boosting, constant temperature and pressure and buck stage, and the parameter in each stage and process be: vacuum: 0��0.04MPa, and the pumpdown time is 0.8��0.9h; Boosting: 0.08��1.0MPa, pressure rising time is 1.2��1.8h; Constant temperature and pressure: 0.7MPa, constant voltage time is 3��5h, and thermostat temperature is 145��160 DEG C; Step-down: drop to normal pressure, the step-down time is 1.2��1.5h, obtains finished product.
Carry out pre-frothing in described 11 parts of urethane foams, 26 parts of rubber grain feeding vapour pressure 0.35MPa, the prefoaming machine being preheating to 125 DEG C, obtain the urethane foam of pre-frothing through 6h slaking.
The present invention compared with prior art tool have the following advantages:
In a word, the practical situation that the present invention is big in conjunction with China's vanadium ore deposit tailings amount, utilization ratio is low, take full advantage of composition structure and the chemical property of various material, defining based on the mineral structure of ca aluminosilicate, hydrated calcium silicate etc., its product performance meet load-bearing for building and non-lbearing wall material specification of quality. The main starting material of building block are vanadium ore deposit tailings, it may also be useful to amount is big, are conducive to solving vanadium ore deposit tailings and store up the problem of environmental pollution processed and bring, for the recycling of vanadium ore deposit tailings opens a new utilization ways.
