Description

Concrete bearing insulating brick and manufacture method thereof

Technical field

The present invention relates to a kind of masonry brick that has both load-bearing and insulation effect, is a kind of insulating brick that a certain amount of polyfoam particle is made that added in concrete mixed material specifically.

Background technology

Existing insulation masonry product mostly is aerating concrete bulk, product is a raw material with levigate quartz sand, lime, cement and gypsum mainly, with the aluminium powder is foaming agent, through batching, stirring, precuring, cutting, maintenance 10～14 hours under High Temperature High Pressure and the fine and closely woven vesicular lightweight aerated concrete goods made.This complex manufacturing, the bubble that produced of getting angry is very unstable, and need carry out steam-cured, relative cost is higher, owing to must be mixed with the lime of more amount in the batching, be used for getting angry with the effect of aluminium powder, determined the ultimate compression strength of the resistance to compression of this product well below concrete; And whitewashing on this masonry surface and often to cause hollowing, is the big common fault of one in the present building operation.In order to reach energy-conservation purpose, there is employing to paste the way that bubble Zhu plate whitewashes again now at wall face, the way that adopts thermal insulation mortar when exterior plaster is also arranged, the former obviously will improve more cost, and the construction technology complexity, and very easily causes to whitewash and flake; Whether correct the latter exist volume problem, and effect is not too obvious.

Concrete has good ultimate compression strength, porous plastics has good heat insulation effect, in concrete mixed material, added the insulating brick that a certain amount of polyfoam particle is made, on the basis that possesses original load-bearing effect, increased heat insulation effect again, and its thermal conductivity is low, be about ordinary concrete brick 1/10-20, meet national present policies and environmental requirement.

Summary of the invention

The invention provides a kind of insulating brick that a certain amount of foam grain is made that added in concrete mixed material, this insulating brick has good ultimate compression strength and cuts apart effect, and has better heat insulation effect.

A kind of concrete bearing insulating brick is characterized in that the concrete mixed material of mainly being made up of cement, sand and aggregate chips, water adds foam grain and water reducer is formed, and its weight proportion is as follows:

Cement 1 weight part, water 0.16-0.55 weight part, sand 1.5-2.5 weight part, aggregate chips 1.5-4 weight part, foam grain 0.05-0.4 weight part, water reducer 0.02-0.03 weight part.

Also can add in the above-mentioned composition: flyash 0-0.25 weight part, hardening accelerator 0-0.02 weight part.

Described foam grain is that particle diameter is the polyfoam particle of the polyfoam particle of 0.5-5mm or the 0.5-5mm that is processed into by useless polyfoam.

The step of the brick producing process of above-mentioned concrete load-bearing insulation is as follows:

A, choose the foam grain of 0.5-5mm or make the polyfoam particle that particle diameter is 0.5-5mm with pulverizer by the polyfoam piece that will give up;

B, get cement, water, sand, aggregate chips, foam grain, flyash, water reducer and hardening accelerator by the proportioning weighing balance, the error in dipping of each prong material is no more than 2.5%;

After c, the batching with aggregate chips, sand, wetting after De foam particle, flyash, cement pour the stirrer hopper successively into, add water and stir into uniform compound;

D, compound are delivered to brick equipment with dolly or e Foerderanlage, pave the moulding of vibrating after going into mould, and the floating back demoulding is transported to stacking place, piles piled bricks, also can make of punching block on placenta;

The concrete brick can carry out natural curing or stacking carries out natural curing or steam-cured after e, the moulding, reach intensity product.

The present invention is same to adopt traditional masonry construction technology, but compares with existing concrete aerating bulk, and the present invention has that complete processing is simple, steady quality, have both advantages such as load-bearing and insulation, cost be relatively low; Solved the recycling problem of polyfoam, turned waste into wealth, can prevent the pollution of the environment effectively, simplified to reaching the related technical measures that building energy conservation is taked; Thermal conductivity is low, is about ordinary concrete brick 1/10-20, meets national present policies and environmental requirement; And whitewash Shi Buhui and cause hollowing, saved greatly to reaching the engineering cost of energy-saving effect.The scope of application of the present invention is extensive.

Embodiment

Embodiment 1:

A, the poly-benzene second alkene foam piece that will reclaim are made the foam grain that particle diameter is 0.5mm-5mm with pulverizer;
