Description
Technical Field
The invention belongs to the technical field of building materials, and particularly relates to active inorganic powder and application thereof.
Background
With the rapid development of social economy, the energy crisis has become a key factor restricting the social development. Building energy accounts for 20-40% of national primary energy consumption, even up to 45% in some developed areas. By 2020, the area of a high-energy-consumption building in China reaches 700 hundred million square meters. Therefore, if the building energy-saving design is not emphasized, the energy crisis of China is directly aggravated. Meanwhile, building energy conservation is one of the important ways to solve the global energy predicament in the future.
Along with the development of the power industry, fly ash discharged by thermal power generation enterprises is increasing day by day, the annual discharge amount of fly ash in China currently exceeds 6 hundred million tons, although most of fly ash is applied to the manufacture of cement, concrete and other products, a large part of fly ash is stored and treated, and a large amount of fly ash discharged in the past year is not effectively utilized. The stacking of the fly ash occupies land and seriously pollutes the surrounding environment, so the effective resource utilization of the fly ash is a problem to be solved. The quality and the dosage of the fly ash are greatly limited in order to ensure the product quality in the existing cement and concrete preparation. Volcanic ash is a natural porous mineral material, and is formed by depositing a large amount of lava fragments and dust which are erupted together with lava during volcanic eruption into the ground surface or waterLoosely or lightly cemented matter. The volcanic ash contains SiO with high activity2And Al2O3The particle has the characteristics of small specific gravity, fine granularity and large specific surface area, and the particle has a developed pore structure. The volcanic ash is a natural mineral which can be regenerated along with volcanic eruption, and the development and utilization cost is low. China is a country with multiple volcanoes, the volcanic ash resources are very rich, and the distribution area is from Heilongjiang to Hainan island in the north. At present, the volcanic ash can not be fully developed in the development and utilization of the volcanic ash in China, and the volcanic ash is only used as a common gelled filler to be applied to concrete and modified asphalt or used as a sound-absorbing and heat-insulating building material, so that the added value of the product is not high. The waste red bricks are common building wastes, and the conventional treatment mode is direct transfer, open-air stacking or burying, so that the waste red bricks occupy land and are not environment-friendly. Or mixing the recycled aggregate with cement, mineral powder, cellulose and xanthan gum powder, adding water and stirring to obtain masonry mortar with different strength grades, or mixing the recycled aggregate with cement, mineral powder, cellulose, short fiber and waterproof powder, adding water and stirring to obtain waterproof mortar with different strength grades, or mixing the recycled aggregate with cement, mineral powder and cellulose, adding water and stirring to obtain ground mortar with different strength grades. The recycling is usually carried out by various types of required raw materials, and the application is limited by the formula and the proportion of the raw materials.
Therefore, development of a new scheme for utilizing the above inorganic substances is urgently needed.

Detailed Description
In one aspect of the invention, the invention proposes an active inorganic powder comprising, according to an embodiment of the invention, an active inorganic substance and a redispersible latex powder. The inventor finds that the active inorganic powder comprises active inorganic matters and redispersible latex powder, has simple components, can be used for manufacturing various plates, sheets, blocks and sections by directly adding water and mixing the slurry, realizes the efficient utilization or the efficient reutilization of the active inorganic matters, is environment-friendly, can be used for replacing cement, steel, plastics and the like, can be recycled and has remarkable economic benefit.
According to an embodiment of the present invention, the specific mass ratio of the active inorganic substance to the redispersible latex powder is not particularly limited, and may be, for example, 84 to 99: 1-16. The inventor finds that the content of the redispersible latex powder can be selected according to the activity of active inorganic matters, for example, the activity of blast furnace mineral powder is higher, the redispersible latex powder with lower proportion can be added, the activity of red brick powder is lower, and the redispersible latex powder with higher proportion can be added to improve the forming performance and the forming speed of the slurry. Specifically, the active inorganic powder may include 84 wt% of active inorganic substance and 16 wt% of redispersible latex powder; or, comprises 86 wt% of active inorganic substance and 14 wt% of re-dispersible latex powder; or, comprises 88 wt% of active inorganic substance and 12 wt% of re-dispersible latex powder; or, comprises 90 wt% of active inorganic substance and 10 wt% of re-dispersible latex powder; or, comprises 92 wt% of active inorganic substance and 8 wt% of re-dispersible latex powder; or, comprises 94 wt% of active inorganic substance and 6 wt% of re-dispersible latex powder; or, comprises 96 wt% of active inorganic substance and 4 wt% of re-dispersible latex powder; or, comprises 98 wt% of active inorganic substance and 2 wt% of redispersible latex powder; or, 99 wt% of active inorganic matter and 1 wt% of re-dispersible latex powder.
According to a further embodiment of the invention, the active inorganic substance may be selected from at least one of red brick powder, volcanic ash, volcanic mud, fly ash, volcanic rock, ground phosphate rock, blast furnace ore powder. Wherein, the red brick is a silicon-based material which is calcined at high temperature and contains rich active components, such as silicon dioxide, aluminum oxide, ferric oxide, calcium oxide and the like. The stacking of construction waste can occupy a large amount of valuable land and resources, and the construction waste can cause the salinization of soil along with rainwater entering soil, still can pollute groundwater simultaneously, causes certain influence to the ecological environment, and the construction waste of piling up in the open air can lead to air pollution and arouse sand and dust weather easily along with wind in dry weather blows off in the air. In the existing technology for recycling red brick powder, the red brick powder is mostly matched with other substances, for example, building wastes, namely red brick powder and fly ash, are used as main matrix raw materials, sea sand or artificial sand is used as an aggregate, solid sodium silicate powder is used as an alkali activator, and metakaolin is used as an additive to prepare a cementing material; or cement, fly ash, asbestos, waste red brick powder, a foaming agent, a foam stabilizer and a water reducing agent are used as raw materials to prepare the light heat-insulating building block; or the decorative magnesium oxychloride cement board is prepared by taking magnesium oxide, magnesium chloride hexahydrate, red brick powder, straw fiber and tourmaline powder as raw materials. The volcanic ash refers to crushed stone and mineral particles which are sprayed from volcanic and have a diameter of less than 2 mm, and in explosive volcanic motion, solid stone and molten slurry are decomposed into fine particles to form volcanic ash, and the volcanic ash has volcanic ash activity. The smaller the diameter of the pozzolan, the deeper the site of entry into the respiratory tract. Particulate matter of 10 microns diameter is used to deposit in the upper respiratory tract5 microns in diameter can enter the deep part of the respiratory tract, and less than 2 microns can reach 100% deep into the bronchioles and alveoli. After inhaled by a person, inhalable particles can be accumulated in the respiratory system, and cause a plurality of diseases. Exposure to coarse particulate matter can attack the respiratory system, inducing asthma. The fine particles may cause heart disease, lung disease, respiratory disease, decrease lung function, etc. In addition, particulate matter in the ambient air is a major cause of reduced visibility and can damage building surfaces. The volcanic ash is natural lightweight aggregate for concrete, such as used in external wall panels, floor slabs and roof slabs; it can also be used for roof insulating layer and heat-insulating layer; it can also be used for small hollow building blocks, heat-resistant concrete, cement active mixed material, clinker-free cement, building finishing material, sound-insulating and heat-insulating material, etc. However, in the field of construction, volcanic ash is often mixed with cement, gypsum, lime and trace additives to prepare light building materials, or mixed with cement, quicklime, clay, construction waste, waste paper, triethylamine, additives, aluminum powder, calcium saccharate, polyoxyethylene fatty alcohol ether, triterpenoid saponin, zinc stearate and benzotriazole to prepare concrete blocks, or mixed with inorganic gel materials (at least one of water glass, gypsum, lime and cement) and gas release agents (at least one of calcium carbide, aluminum powder and hydrogen peroxide) to form ecological building heat-insulating energy-saving plates and the like. Volcanic mud is a volcanic product, and is non-viscous mud which is grey white, dark grey to black and takes volcanic glass as a main component. Volcanic mud contains more than thirty trace elements and minerals: silicon, aluminum, magnesium, calcium, iron, titanium, sulfur, phosphorus, sodium, copper, zinc, selenium, cobalt, manganese, molybdenum, and the like. These components stabilize the physical properties of volcanic mud and are widely used in various fields. In indoor decoration, the oxygen forest source volcanic mud environment-friendly wall material is popular in high-end home decoration due to the functions of zero formaldehyde, lasting adsorption and efficient formaldehyde decomposition. For example, the environment-friendly and energy-saving building material is prepared by mixing recycled aggregate, vitrified micro bubbles, portland cement, quartz sand, montmorillonite powder, mica powder, polypropylene fiber, hydroxypropyl methyl cellulose, myristic acid, wormwood powder, sawdust powder, waste asbestos, soy protein adhesive, preservative, retarder, water reducer and water; or with activated slag powder, borax and bentoniteThe environment-friendly composite reinforced cement is prepared from modified sepiolite powder, carboxymethyl cellulose ether, basalt fiber, sodium silicate, building latex solution, an expanding agent and an early strength agent. Fly ash is a tiny soot particle discharged from the combustion process of fuel (mainly coal), and belongs to hazardous waste. According to the coal consumption condition in China, about 250-300kg of fly ash is generated by burning 1t of coal. If a large amount of fly ash is not controlled or treated, air pollution can be caused, the fly ash enters water to foul a river channel, and certain chemical substances in the fly ash cause damage to organisms and human bodies. The fly ash mainly contains silicon dioxide (SiO)2) Alumina (Al)2O3) And iron oxide (Fe)2O3) And the like, and are widely used for manufacturing cement and various light building materials. For example, the mixture is mixed with lime, fine aggregate, exciting agent and water to prepare steam-pressed brick, or mixed with epoxy resin and glaze to prepare decorative board, or mixed with bamboo bits and adhesive to prepare inorganic bamboo section. Volcanic rock (volcanic rock or pumice) is a vitreous lava with dense air holes formed by rapid escape and expansion of internal gas due to rapid reduction of pressure after rapid cooling of magma in volcanic eruption. It features high strength, thermal insulation, sound absorption, fire-proofing, acid-base resistance, corrosion-resistance, no pollution and radioactivity. The volcanic rock is hard, can be used for producing ultra-thin stone plates, has the glossiness of more than 85 degrees after the surface is finely ground, has bright and pure color and elegant and solemn appearance, is widely used for decorating external walls of various buildings, paving the ground of municipal road squares and residential districts, and is particularly the preferred stone for various antique buildings, European-style buildings and garden buildings. For example, the light heat-insulating building material is prepared by mixing with rice husks, soybean shells, quartz stone powder and an adhesive, or is prepared into a volcanic rock cement brick by mixing with cement, or is prepared into a building energy-saving material with a mildew-proof function by mixing with aluminate refractory cement, expanded vermiculite, clam shell powder, cypress sawdust, broken glass fibers, corncob core powder, white carbon black, an ultraviolet absorbent, magnesia, a water reducing agent, a crosslinking agent and a mildew preventive. The main component of the phosphate rock powder is fluorapatite (chemical formula, Ca)10(PO4)6F2) Contains 10-35% of total phosphorus (phosphorus pentoxide), 3-5% of phosphorus is dissolved in weak acid and can be absorbed by crops, and most of other crops are difficult to absorb directlyIt belongs to an insoluble phosphate fertilizer. Generally applied as fertilizer in soils with high acidity and phosphorus deficiency. The blast furnace mineral powder is a mineral admixture with potential activity, which is obtained by grinding water-crushed granulated blast furnace slag to a specified fineness. At present, blast furnace mineral powder is mainly used as a blending material of concrete to replace part of cement, and is one of the composition materials for producing high-strength concrete. It can be seen that the active inorganic substances are mostly used as auxiliary materials, the usage amount of the active inorganic substances in the product is limited, the active inorganic substances cannot be fully utilized, and meanwhile, the formula composition is complex in the practical application process. The application directly mixes at least one of the active inorganic substances with the redispersible latex powder to form the active inorganic powder, so that the using amount of the active inorganic powder is obviously increased, the formula is simple, water is directly added for size mixing during use, various sheets, plates, blocks or sectional materials can be formed according to requirements, solid waste or hazardous waste is recycled, and the obtained product has good environmental protection performance, is not saltpetering and is more environment-friendly compared with a cement board; compared with a steel plate, the steel plate is not rusted; compared with a wood board, the wood board is not easy to fade and is water-resistant; compared with plastic plates, the plastic plate has excellent aging resistance. Furthermore, various active inorganic substances can be selected to be mixed with the redispersible latex powder, so that the diversity of the active inorganic powder is improved, local materials are conveniently obtained, and the cost is saved.
According to still another embodiment of the present invention, the specific surface area of the active inorganic substance may be not less than 410m2/kg and/or a particle size of 300-30000 mesh. The inventor finds that with the increase of the specific surface area and/or the reduction of the particle size of the active inorganic substance, the active inorganic substance generates micro-cracks on the surface and inside of the particles due to strong mechanical impact, shearing and grinding action and mutual extrusion and collision action among the particles in the grinding process, so that polar molecules or ions can enter internal cavities of a glass body structure more easily, the dispersion and dissolution of the active inorganic substance are promoted, the hydration reaction speed of the active inorganic substance is improved, and the activity index of the active inorganic substance is further promoted to be rapidly increased along with the increase of the specific surface area and the activity of the active inorganic substance is increased.
