Description
Technical field
The present invention relates to a kind of light Maoyi brick and preparation method thereof, belong to field of inorganic nonmetallic material.
Background technology
The sandy soil that the mobility that drift-sand is formed on earth's surface after being through natural wind carrying, classification, deposition is extremely strong, its particle is tiny, and its particle diameter is mainly distributed between 0.074 ~ 0.250mm, and the particle being greater than 0.25mm is few, is only 0.1%.And the particle being less than 0.074mm also only has less than 9%.Nonuniformity coefficient is about 1.35.Its stable components, have about 90% in material composition for light mineral in silicon-dioxide (quartz), feldspar, calcite etc., heavy mineral content is few but kind is more, reaches 16 kinds ~ 22 kinds.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of light Maoyi brick being main production raw material producing shaped with drift-sand, Mao Yishi.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of light Maoyi brick, comprises the raw material of following weight percent: drift-sand 69% ~ 88%, Mao Yishi 10% ~ 27%, whipping agent 1% ~ 3%, stablizer 0.01% ~ 0.5%.
The invention has the beneficial effects as follows: the present invention is main raw material with drift-sand, opened up the frontier of building brick, control a large amount of losses in soil, decrease drift-sand to the broken evil of physical environment and the impact on human lives.
Compared with conventional clay, because drift-sand mobility is extremely strong, so exploitation is convenient, significantly can reduce product cost, drift-sand and Mao Yishi are carried out proportioning, is conducive to improving the processing performance of material, and the product produced after high temperature, high pressure biochemical reaction possesses, and Dimensions deviation is little, good heat insulating, hardness, intensity high.
Domestic in Ordos, inner Mongolia Wushen Banner, drift-sand distribution area is 2821.28 square kilometres.According to data, once selected 15 square kilometres of domestic drift-sands carried out geological resource detailed survey, report analysis is little in the drift-sand mineral composition content of this areal distribution, and most mineral composition stable content, can be used as the raw material site of extensive industrialized development.The major ingredient of Wushen Banner drift-sand is SiO
2, Na
2o, MgO, P
2o
5, CaO, Al
2o
3deng, wherein SiO
2content account for about 75%., non-plastic little according to Wushen Banner phase drift-sand stable components, moisture, be easy to the features such as storage, be specially referred to as the earth's crust mineral substance of " Mao Yishi " as starting material integral part of the present invention with the local one in Wushen Banner.
Described whipping agent refers to, makes the material of object material pore-forming, and it can be divided into chemical foaming agent and pneumatogen and tensio-active agent three major types.Chemical foaming agent is that those can discharge the gas such as carbonic acid gas and nitrogen after thermal degradation, and forms the compound of pore in polymkeric substance composition; Pneumatogen is exactly the change that foam pore is the physical aspect by a certain material, is namely formed by the dissolving of the expansion of pressurized gas, the volatilization of liquid or solid; Whipping agent all has higher surfactivity, effectively can reduce the surface tension of liquid, and surrounds air in the electric double layer arrangement of liquid film surface, forms bubble, then forms foam by single isolated bubbles.
Chemical foaming agent have again inorganic foaming agent and organic blowing agent point.Organic blowing agent mainly contains following a few class: azo-compound; Sulfonyl hydrazines compound; Nitroso compound;
Inorganic foaming agent mainly contains following classification: sodium bicarbonate, Sodium bicarbonate are a kind of inorganic foaming agents, white powder, proportion 2.16.Decomposition temperature is about 100 ~ 140 DEG C, and releases part CO
2, lose whole CO to when 270 DEG C
2.Water-soluble and be insoluble to alcohol.
Conventional pneumatogen has lower boiling alkane and fluorocarbon.Skellysolve A, normal hexane, normal heptane, sherwood oil (petroleum naphtha), trichlorofluoromethane (being called for short Freon11), Refrigerant 12 (being called for short Freon12), dichloro tetrafluoro ethane (being called for short Freon114).
Conventional surfactant-based whipping agent has: sodium lauryl sulphate (K12), polyoxyethylenated alcohol sodium sulfate (AES), rosined soap class whipping agent, animal/vegetable protein class whipping agent, spent pulping liquor etc.
Described stablizer is NaHCO
3, Na
5p
3o
10, Na
2siO
3or NabO
3-4H
2o etc.
The beneficial effect that light Maoyi brick of the present invention adds whipping agent is:
1, whipping agent contains exciting agent, fully the gelling material in light material can be activated, promote hydration reaction, improve cohesive force, overcome and introduce bubble in light material and the defect that causes intensity to reduce.
2, whipping agent adds guarantor and is moulded part, and when not reducing whipping agent performance, light-weight wall material has good interior poly-water retaining function, can reduce endochronic model significantly.
3, whipping agent has good hydrophilic complex ability, can mix with soft, hard water matter, the unlikely whiting occurring calcium, magnesium plasma reduction, deposited phenomenon.
Below for and " Wushen Banner, Erdos, Inner Mongol " domestic drift-sand, Mao Yishi chemical constitution table (see table 1).
Another technical scheme that the present invention solves the problems of the technologies described above is as follows:
A preparation method for mao adopted brick, comprises the following steps: by weight percent be 10% ~ 27% Mao Yishi first carry out active Transforming, obtain hair justice stone granulate; Add the drift-sand that weight percent is 69% ~ 88% again, carry out ball mill pulverizing together, obtain compound particles; And then add weight percent be 1% ~ 3% whipping agent and weight percent be the stablizer of 0.01% ~ 0.5%, constantly carry out being stirred to evenly, and then add water and carry out biochemical reaction, finally shaping, obtain described hair justice brick;
Wherein, the gross weight of described drift-sand and Mao Yishi and the weight ratio of described water are 30 ~ 50: 100.
CaO in Mao Yishi extracts by described active Transforming referring to, with the Sio of drift-sand
2abundant combination.
Described ball milling refers to, utilizes the shock action of grinding element (as steel ball, pebbles etc.) that falls and grinding element and the grinding of ball milling inwall and is mixed by crushing material.When ball milling rotates, due to the rubbing effect between grinding element and ball milling inwall.Grinding element is fallen after on the direction band rotated again.Such material is just continuously pulverized.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the order number of described hair justice stone granulate is 100 ~ 300 orders.
Further, after described ball mill pulverizing, the order number of compound particles is 100 ~ 300 orders.
