Description
Technical field
The present invention relates to a kind of building heat preservation materials for wall dry powder additive, be specifically related to be used to improve the additive of the heat-insulating property and the splitting resistance of riverway sludge self-heat preserving sintering porous brick.
Background technology
Riverway sludge is one of important kind of a kind of municipal solid wastes.City river has accumulated a large amount of inorganicss and organism because for many years sewage is in line in river silt, by and overlying water between diffusion and exchange, become the secondary pollution source.The training of channel in the densely covered networks of rivers such as China water transport river course, rivers and lakes will produce a large amount of mud, and along with the planning and the upgrading in river course, Shanghai, will produce more riverway sludge.How effectively, suit measures to local conditions, the recycle riverway sludge has great importance to avoiding bringing secondary pollution, resource recycling, suggestion conservation-minded society.Both at home and abroad all in the effective method of comprehensive utilization and the technology of active research mud.
Concerning building materials industry, along with constant development of economy, the demand of conventional gelling material such as cement and materials for wall increases gradually, is faced with the day by day deficient condition of starting material equally.Therefore, many countries, particularly developed country have all dropped into great amount of manpower and material resources, developing high-tech, and research and utilization nature and industrial waste substitute natural starting material, produce to reach ecological eco-cement and the materials for wall that requires.The comprehensive utilization riverway sludge is one of effective way of environment protection and changing waste into resources.Along with the fast development of China's capital construction, the demand of building brick is also increasing.Originally the traditional brick-making technology of China is to utilize vitrified bond brickmaking, because it need plough in a large amount of diggings, basic farmland is caused a large amount of destruction, and country prohibites and produces and use clay solid brick, limit production and use porous clay brick.Therefore some Bricks and Tiles Plants are faced with the development predicament of shortage of raw materials.Utilize the riverway sludge instead of clay, produce sintered perforated brick, not only can avoid it to second environmental pollution, and can realize the Sustainable development of Bricks and Tiles Plant.At present, domestic a plurality of patents of invention of having applied for have proposed to utilize mud to produce vitrified brick, as application number 200610040094.0,02137142.3,200620077568.3 etc.From these patents, at present, the riverway sludge sintered perforated brick still exists some problems to need further to solve, and the one, the river course sludge content is lower in the adobe raw material, can not realize the instead of clay of mud 100%; The 2nd, riverway sludge vitrified brick splitting resistance is relatively poor, fraction defective is higher; The 3rd, the heat-insulating property of this brick is relatively poor, can not satisfy the light energy conservation heat-insulation and heat-preservation requirement of modern architecture to materials for wall.The heat-insulating property how research effectively improves sludge self-heat preserving sintering porous brick is one of important channel of realizing building energy conservation, has great practical significance.
Summary of the invention
Technical problem to be solved by this invention is to overcome defective of the prior art, a kind of dry powder additive that is used to make the riverway sludge self-heat preserving brick is provided, utilize this dry powder additive, can increase substantially splitting resistance, interior porosity, the self-heat conserving performance of riverway sludge self-heat preserving brick.
One aspect of the present invention provides a kind of dry powder additive for riverway sludge self-heat preserving sintering porous brick, and its component and mass percent are as follows:

Among the present invention, wood chip is that exsiccant, particle diameter are 0.5～1mm wood chip.
The basalt fibre of the preferred diameter 5-10 of basalt fibre μ m, length 5～15mm.
Wood fibre is the lignin fibre of diameter 5-10 μ m, length 5～10mm preferably.
The particle diameter 0.3-2mm of polystyrene foam particles.
The particle diameter 0.5-3mm of cinder.
The preparation method of dry powder additive of the present invention is: select various starting material in accordance with regulations, press formula rate and add required wood chip, basalt fibre, wood fibre polystyrene foam particles, cinder in stirrer, stir and get final product.Also can directly add in proportion in the riverway sludge adobe.
Second aspect present invention discloses the application of above-mentioned dry powder additive in the preparation riverway sludge self-heat preserving sintering porous brick.
Third aspect present invention discloses a kind of preparation method of riverway sludge self-heat preserving sintering porous brick, is included in that to add weight percent in the raw material be 1～5% above-mentioned dry powder additive.
Add dry powder additive of the present invention in the riverway sludge self-heat preserving brick, it not only can improve the early stage splitting resistance and the later strength of adobe, and because of during the adobe high-temperature roasting or self the burning, or because decomposition discharges gas under the high temperature, or in goods, stayed little pore in a large amount of different apertures because of air hole structure itself, make brick have higher porosity, thereby reduce product density significantly, thermal conductivity, improve the heat-insulating property of riverway sludge sintered perforated brick greatly.In the common building structure is gone along with sb. to guard him, can realize that building energy conservation is more than 50%.
