Description

Light foaming sandwich heat and moisture preserving building block
Technical field
The present invention is a kind of novel energy-saving environment-friendly constructional materials, especially a kind of needn't sintering, normal temperature and pressure, the energy conserving and environment protective building blocks of curing molding belongs to baking-free building block (brick) voluntarily, belongs to building brick, building block technique field.
Technical background
The preparation method of building brick (building block) is divided three classes: sintering class, stream curing class, natural curing class.Deficiency is respectively arranged: the sintering class, as the clay common brick, country forbids to produce; Stream curing class: as fly ash building block, sand-lime building block etc., the big consumption lot of energy of equipment investment.The natural curing class, as colliery wastes brick, colored paving block etc., more than the natural curing 10 greatly, the time is long.Can't produce winter.Resume combustion coal class is a lot of in the prior art, is generally the solid heavy (unit weight surpasses the 2200kg/ cubic meter greatly) that connects, and a large amount of hollow bricks is also arranged, and porous brick is as paving stone, simple and easy house owed by a citizen brick or the like
Flyash, slag, various dump slag soil, silt, clay, slity soil or the like all can use, and be cheap and easy to get.
Resume combustion coal class is a lot of in the prior art, is generally the solid heavy (unit weight surpasses the 2200kg/ cubic meter greatly) that connects, and a large amount of hollow bricks is also arranged, and porous brick is as paving stone, simple and easy house owed by a citizen brick or the like.
Common building block generally has following weak point: the water absorption rate height, be difficult for whitewashing, and easily cause and whitewash irregular slight crack, cause rendering layer to come off.In addition, drawing materials of common building block is also more limited, can not turn waste into wealth, and is not easy to reduce production costs.
And general traditional building block making comprises: electronic proportioning, stir in (aluminium powder, quicklime, gypsum), and moulding, foaming, high-pressure steaming and cultivating, cutting is dispatched from the factory.In the middle of these traditional processing steps, the high-temperature steam curing process need 24 hours, and its shortcoming is obvious, the time-consuming material that takes.
Summary of the invention
The present invention aims to provide that a kind of material source is extensive, and cost is low, environmental protection and energy saving, and the building block of free of calcining and steam curing, and also a large amount of bubbles add tolerance and make building block become lightweight in the building block, the well behaved light foaming sandwich insulation blocks of thermal-insulation energy-conservation (brick); The heat preserving exterior wall body or the interior body of wall that can be used for building construction in a large number, the partition board between the room.
The technology of the present invention prescription is a kind of comprehensive technology of uniqueness, has complementary advantages, and various raw material, proportioning is an amount of, the desirable chief.Among traditional manufacture craft, add special preparation, simplified conventional process flow greatly.Traditional brick is to mix aluminium powder, limestone and gypsum to fire and form, the technology of the present invention is not then used limestone, gypsum, is to merge gather materials (such as string), blowing agent, composite curing agent, coagulating agent (cement) of major ingredient (flyash, slag), composite light to be made.
The building block of adopting technical solution of the present invention to make mainly is made up of interior folder warming plate and foaming layer, and the centre is interior folder warming plate, and both sides are foaming layers.
In the folder warming plate general what adopt is that preferential what adopt is polyphenyl plate.
What make that this building block adopts is that the use of composite light material reduces the unit weight data of goods greatly, can reach 600-700Kg/m 3
The weight proportion of described major ingredient is: flyash 30-50 part; Slag 20-40 part;
Described composite light material comprises: various dump slag soil, silt, clay, slity soil; String is as straw, straw, maize straw, sawdust etc.; Mineral matter: perlite, fine particle calcium carbonate or the like; Waste plastic foam or the like.These materials are proportioning arbitrarily.Described composite light material weight proportioning is about 5-20 part
Described composite light material can adopt the Chemical Pretreatment mode, and chemical overlay film strengthens its hydrophily greatly, make light aggregate easily and coagulating agent combine closely, increased the intensity of goods, reduced the unit weight of goods, the also corresponding reduction of cost of production.
The use of compound curing compound can make the raw material source more extensive, and a large amount of dump slags all can use, and reduces cost greatly.Also can shorten curing time greatly, shorten the production cycle, improve the utilization rate in place.
Add the composite curing agent of 1-3 part in the integral formula, a large amount of dump slags, building waste all can use, and reduce cost greatly, and also solidifiable agent consumption reduces about 50%, reduces cost.This product is solidified fast, make this product closed pore uniform in foaming, cement is connected with interior folder warming plate solidifies together.
Main component: slag 70%
Alkaline activating agent 25%-30% preferentially adopts silicate of soda
Surfactant 0.01%-0.2% preferentially adopts benzene sulfonic acid
General curing compound 2-5% mixes levigate the getting final product of stirring
Foaming agent is used for prescription alleviates product weight, and thermal and insulating performance strengthens, the composite energy-saving environment protection requirement.Material whipping process in the prescription, constantly in the bleed foaming mixture, during the normal temperature and pressure moulding, owing to be not communicated with more stablely in the bubble mutually, a large amount of bubbles can remain in the building block brick, and building block brick weight is alleviated greatly, and hold performance such as thermal insulation sound insulation.Incorporation is the 0.5%-1.5% main component of coagulating agent: sodium abietate 8-15%
Gelatine 3-8%
NaOH 10-20%
Neopelex 5-10%
Water 65-75%.
Coagulating agent: mainly in prescription, play cementation, simultaneously building block weight is alleviated greatly.Its major ingredients is cement 13-30 part.
Made building block needn't be washed, and this main cause is to have special composite curing agent to add in the prescription, and cement consumption reduces by 5 percent, and cost reduces greatly, and building block (brick) intensity is greater than 1OHpa.
The key step of technical solution of the present invention is followed traditional building block manufacture craft substantially, but because the use of special preparation, the part technological process can be saved and simplify to the technical program, and specifically: electronic proportioning---------------steam-cured (steam-cured naturally)---check---dispatches from the factory in the demoulding in maintenance to water mold forming (interior folder warming plate) to stir (blowing agent, composite curing agent, composite curing agent).
The light foaming sandwich insulation blocks intensity height of producing, load-bearing is big, light weight, construction is simple and easy to whitewash, and is low with performance product relative price, and a large amount of bubbles add tolerance 3-5% in the building block, owing to used folder product in homemade foaming agent and the cystosepiment in the prescription, can make building block become lightweight, capacity is to the 450-650kg/ cubic meter, thermal-insulation energy-conservation 30-50%.Also can prevent noise jamming, moistureproof (wash water power is low).In process of production, the production equipment simple general-purpose, the technological process of production is simplified, and is with short production cycle, the output height, energy-conserving and environment-protective, with low cost, can form large-scale production.
The advantage of the technical program production building block (brick): make the interior a large amount of bubbles of building block add tolerance 3-5%, owing to used folder product in homemade foaming agent and the cystosepiment in the prescription, can make building block become lightweight, capacity is to the 450-650kg/ cubic meter, thermal-insulation energy-conservation 30-50%.
