Description
Technical field
The present invention relates to a kind of production method of inorganic heat preservation plate, be mainly used in the heat insulating of construction industry exterior wall or interior wall, specifically relate to a kind of method of producing the inorganic heat preservation PLASTIC LAMINATED with industry by-product gypsum.
Background technology
2009, about 1.18 hundred million tons of China's industry by-product gypsum generation, comprehensive utilization ratio only is 38%.Wherein, about 4,300 ten thousand tons of desulfurated plaster, comprehensive utilization ratio about 56%; About 5,000 ten thousand tons of phosphogypsum, comprehensive utilization ratio about 20%; About 2,500 ten thousand tons of other by-product gypsums, comprehensive utilization ratio about 40%.The volume of cargo in storage of industry by-product gypsum accumulation at present surpasses 300,000,000 tons, and wherein, desulfurated plaster is more than 5,000 ten thousand tons, and phosphogypsum is more than 200,000,000 tons.Industry by-product gypsum is stored up in a large number, and both land occupation was wasted resource again, and acid and other objectionable impuritiess that contain pollute surrounding enviroment easily, have become the important factor of restriction China's coal-firing units gas desulfurization and phosphatic fertilizer company Sustainable development.Therefore, how improving the utilization ratio of industry by-product gypsum, is the problem that people yearn for solution always.
In the existing lagging material, the overwhelming majority all is inflammable, on October 9th, 2008, " longitude and latitude 360 degree " Gemini mansion presence of fire in the Harbin of building.On November 15th, 2010, Jiangzhou, road, Yuyao, Shanghai road, 28 a floor residential building that carrying out the insulating layer of external wall construction are on fire, cause 58 people wrecked altogether.On February 3rd, 2011 was called as the prosperous mansion presence of fire of feudal dynasties ten thousand of Shenyang first high building, and big fire has continued 10 hours.In these accidents, combustion-supporting arch-criminal is exactly lagging material.
The applicant finds in long-term work sutdy, produce the inorganic heat preservation plate by industry by-product gypsum, can well solve the problem of the low and lagging material safety performance of industry by-product gypsum utilization ratio, this province of gypsum is exactly fire-retardant material, the inorganic heat preservation of producing by foaming technique, have A1 level security fire resistance, effect of heat insulation is good, and soundproof effect is also comparatively desirable.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the present invention is to provide and a kind ofly both can consume a large amount of industry by-product gypsums, and industry by-product gypsum is processed into insulation, heat insulation, fp inorganic heat preservation PLASTIC LAMINATED, namely produces the method for inorganic heat preservation PLASTIC LAMINATED with industry by-product gypsum.
The technical solution used in the present invention is as follows:
Method with industry by-product gypsum production inorganic heat preservation PLASTIC LAMINATED may further comprise the steps:
1., 1-5 part foaming agent and 1-5 part foaming agent are added in 40-60 part warm water foam;
2., 650-750 part industry by-product gypsum, 25-35 part metakaolin, 15-25 part alum, 90-105 part cement, 30-70 part slag, 45-55 part flyash, 45-55 part calcium dioxide and 80-120 part water are evenly mixed, put into the good liquid of foaming, progressive die tool maintenance demoulding after 24 hours.
Preferred version may further comprise the steps:
1., 2 parts of foaming agent and 3 parts of foaming agents are added in 50 parts of warm water foam;
2., 700 parts of industry by-product gypsums, 30 parts of metakaolins, 20 parts of alum, 100 parts of cement, 50 parts of slags, 50 parts of flyash, 50 parts of calcium dioxides and 100 parts of water are evenly mixed, put into the good liquid of foaming, progressive die tool maintenance demoulding after 24 hours.
More perfect is,
Described industry by-product gypsum is 200-300 purpose modified industry by-product gypsum for the ball milling fineness.
Described foaming agent is one or both in aluminium powder, the hydrogen peroxide.
Described foaming agent is one or both in rosin, the sodium lauryl sulphate.
Described warm water is 40-45 degree centigrade water.
The inorganic heat preservation PLASTIC LAMINATED of the present invention preparation is added industry by-product gypsum and is reached more than 60%, belongs to the useless building material of typical energy-saving ring Poly, and product has effects such as insulation, heat insulation, A1 level fire prevention.Can reach
The energy-conservation requirement of country, digestion industry by-product gypsum that again can bigizationner.
Beneficial effect of the present invention shows:
1, reduced the production cost of building trade material, made the material of producing stand the competition in market, can allow enterprise obtain maximum interests; Do not have secondary pollution in the production process, construction can make things convenient for.
2, the inorganic heat preservation PLASTIC LAMINATED is main raw with the industry by-product gypsum, himself distinctive molecular structure of gypsum itself, contain 20% moisture content (crystal water and free-water), through national fixed fire extinguishing system and fire retarding component quality supervision and test center (Tianjin) test, product has A1 level security fire resistance, heat-insulating capability is higher 5 times than concrete, and good heat insulating and sound insulating characteristic is arranged again.
The heat-insulating property of the gypsum that 1cm is thick is equivalent to the thermal and insulating performance of the brick and tile layer of 3cm.
