Description
Technical field
The present invention relates to the brick or the building block of buildings, especially relate to the insulating brick or the insulation blocks of buildings.
Background technology
The insulation measure of construction wall commonly used at present; Generally be to smear certain thickness thermal insulation mortar or plug-in warming plate at the ordinary masonry exterior wall; But the construction of this way is loaded down with trivial details, long construction period, cost are high, and metope is easy to crack, seepage, has a strong impact on the heat insulation effect of buildings.To this situation, directly the brick of cold-proof heat insulation and building block are developed.Early stage good heat insulation effect brick and building block are mostly processed by high temperature sintering.Produce this sintered type insulating brick and building block and need consume mass energy, and contaminate environment, therefore can be substituted by unburned shaped brick and building block gradually.
In recent years, the research of burning free type insulating brick and building block was unfolded just gradually, but ripe with practical at present baking-free heat preservation brick technology does not occur as yet.In application number is 200710072525.6 patent documentation, a kind of " novel cold-proof baking-free heat preservation brick " disclosed, it is to be raw material with cement, middle sand, plant rice husk, water.Though the plant rice husk has heat retaining property preferably, in this patent, the content of plant rice husk is up to 50%; Cellulosic fiber core is a hollow tubular structure; Also have a large amount of emptying apertures in the cell walls, according to capillary effect, these paths and hole can absorb large quantity of moisture and be transported to each position of brick body; Make the brick body receive freeze/thaw harm more easily, and make brick body size unstable; In addition, this water-absorbent and moisture conductivity can make soluble chemical substance at brick body inside and surface deposition, thereby cause the brick body to be corroded and weathering, and too high vegetable fibre content makes this brick in practical application, be restricted.
In application number is 200910002407.7 patent documentation; A kind of " light thermal-insulation partition block (brick) " disclosed; It is to be heat-insulation base material with polyphenyl foam particle, waste and old polyphenyl foam particle or pearlstone, is sticker with cement, is aggregate with sand or flyash; Be prepared into concrete, cut into the building block of required size again.The document is not described in detail the proportioning of each component, and the quality examination data of brick are not provided yet, because polyphenyl foam particle resistivity against fire is poor, the combustion gases poisonous and harmful bans use of in some cities at present.
Summary of the invention
The present invention is directed to the not strong shortcoming of above-mentioned baking-free heat preservation brick practicality; Provide a kind of duplication of production on a large scale, quality index to satisfy the baking-free heat preservation brick of user demand fully; And its main raw is environmental wastes such as mud, chip, the superior effect of have save energy, utilize waste, protecting farmland, optimizing the environment.
Technical scheme of the present invention is following:
Starting material and the weight part ratio thereof of producing the baking-free heat preservation brick are: 490 ~ 590 parts of chips, 260 ~ 320 parts of silicate cements, 20 ~ 60 parts in mummification mud; 4 ~ 5 parts in lime, 1.8 ~ 30 parts of pearlstones, 2 ~ 5 parts of stalks; 3 ~ 5 parts of nutshells, 2.1 ~ 1.9 parts of animal fibers, 107 ~ 130 parts in water; Wherein chip is yellow sand, rice sand or small particle size stone.
In above-mentioned raw materials, chip and mud are as aggregate, and silicate cement and lime are as agglutinate, and pearlstone is as lagging material, and stalk, nutshell and animal fiber are as anticracking material and insulation auxiliary material, and water is as thinner.
The production stage of baking-free heat preservation brick is:
(1) with the sludge dewatering machine with the sludge dewatering mummification;
(2) stirring in the lime input exsiccant mud, the calcium hydroxide composition of lime is simultaneously to the mud sterilization and disinfection;
(3) mixture of mud and lime is deposited on the vacant lot of spacious canopy hung 2 ~ 3 days, stir every day once, carry out the nature deodorizing;
(4) use kibbler that stalk, nutshell and animal fiber are ground into the microparticle that particle diameter is 3 ~ 5mm simultaneously;
(5) all raw material is dropped into stirrer successively, stir into uniform mixture;
(6) through material conveyor the mixture of step (5) is sent in the forming mould of brick press, be processed into the brick body through vibration and pressurization, its moulding pressure is 2.5 ~ 4MPa;
(7) brick carried out vapor cure 13 ~ 15 hours after body formed, and curing temperature is 85 ~ 95 ℃, perhaps carries out natural curing 7 days; Curing temperature is 0 ~ 15 ℃; Make the intensity of brick rise to 70% of design strength, put into the finished product yard then, promptly obtain finished product behind the natural air drying.
Technique effect of the present invention is:
1, added lime in the raw material of product of the present invention, lime can strengthen the anti-permeability performance of brick body, and the water tolerance of brick body is improved, and improves the ultimate compression strength of brick body.In addition, the staple of lime is Ca (OH)
2, have strong basicity, the protein of bacteria composition is lost activity, mud is carried out disinfection.
2, added stalk, nutshell and animal fiber in the raw material of product of the present invention, the animal and plant fiber is elongate, and being distributed in the brick body can bridge joint brick body microparticle, makes the brick body have good antidetonation resistance to cleavage; Secondly, because the hollow structure of animal and plant fiber can completely cut off heat transfer, make heat insulation effect of the present invention obtain large increase as the insulation auxiliary material; The 3rd, the animal and plant fiber quality is light, has alleviated the deadweight of product of the present invention.
3, added nutshell in the raw material of the present invention, the hardness of nutshell is very big, can improve the ultimate compression strength of brick body.
4, in the raw material of the present invention be the insulation major ingredient with the pearlstone, good heat preservation performance is from heavy and light.
5, be aggregate with chip and mud in the raw material of the present invention, chip and mud are rubbish and waste, use in a large number chip and mud not only can efficent use of resources, turn waste into wealth, can also reduce production costs.
6, the present invention is through proper raw material proportioning, and resulting baking-free heat preservation brick cost is low, quality is high, practical.At first the cohesiveness of chip and mud is relatively poor, therefore adds suitable silicate cement and lime as sticker, makes it can meet the requirements of ultimate compression strength and water tolerance; Secondly, the cost of pearlstone is higher, thereby adds cheap stalk, nutshell and animal fiber, has not only guaranteed heat retaining property, and has further improved ultimate compression strength, shock resistance, and alleviated the deadweight of brick body.This baking-free heat preservation brick has reached the fire protection requirement of national A level, can be widely used in the thermal insulation wall surface of buildings.
