The waste foam concrete insulation material is mainly prepared from waste polystyrene foam, and thus the recycling rate of waste can be effectively increased, energy resources are saved and the environment is protected.
Description
Technical field
A kind of waste foam concrete thermal-insulating material of the present invention and preparation method thereof relates to a kind of building thermal insulation material, belong to building material field, particularly a kind of cement, waste polystyrene foam beads add lagging material that function regulator makes and the preparation method of this lagging material.
Background technology
The heat preserving and insulating material that utilizes in the market mainly contains perlite block, color steel, polyphenyl foam plate etc., these miscellaneous products, the problem that all has some technical elements, the perlite block product cost is lower, drum expands but this product has absorbed water, power consumption is high, color steel, cost is higher, and the noisiness that drenches with rain is large, the life-span weak point gets rusty, polyphenyl foam is heat insulation, cost is higher, ultimate compression strength is low, polyphenyl foamed board and its levels cement concrete layer are not bonding, life-span is short, carrying out patent retrieval through prior art finds, patent of invention number (02138293.X) has been put down in writing a kind of polybenzene foamed concrete thermal-insulating material and preparation method thereof, wherein mainly utilize the waste product polyethylene in conjunction with cement and foaming agent and polybenzene foamed concrete thermal-insulating material of making and preparation method thereof, this lagging material, its component and content are: 15 millimeters-30 millimeters granules of polystyrene: 4%～10%, cement: 81%～91%, foaming agent: 0.4%～1%, water: 4%-8%, it is to utilize foaming agent so that cement plays the hole, in the situation that does not affect cement character, combine well with granules of polystyrene and form, there is following technical disadvantages in above-mentioned technology, utilizes 15 millimeters-30 millimeters granules of polystyrene, and particle is larger, cement can not be combined well with granules of polystyrene, reduce heat insulation effect, the foaming agent of use is not suitable for extensive Application in Building, and cost is higher.
Summary of the invention
In order to address the above problem, a kind of waste foam concrete thermal-insulating material of the present invention and preparation method thereof provides a kind of cement, aggregate, polystyrene foam particles to add lagging material and preparation method that function regulator is made.
A kind of waste foam concrete thermal-insulating material of the present invention and preparation method thereof is achieved in that lagging material of the present invention and component and content thereof are, 2 millimeters-10 millimeters granules of polystyrene: 5%～15%, cement: 20%～50%, aggregate: 15%～25%, function regulator: 0.2%～3%, water: 4%-7%, all percentage ratios are mass percent.
The production method that above-mentioned each component is made lagging material of the present invention is:
At first 0.2%～3% function regulator and the water of 4%-7% are fully mixed;
2 millimeters-10 millimeters granules of polystyrene are put into the water that mixes, fully mix more than 1 minute;
20%～50% cement and 15%～25% aggregate are fully mixed, then be mixed together stirring with soaked granules of polystyrene and water, after fully stirring, utilize mould to lay the smooth bulk of making;
Function regulator with 0.2%～1% adds cement and adds water and stir into slurries, covers the block surface of making, and makes slurries naturally osmotic after coagulation and forms the lagging material of an integral body;
At the heat insulation material surface of making, brush one deck waterproof paint.
The function regulator that the present invention adopts is comprised of whipping agent, suds-stabilizing agent, water reducer, hardening accelerator and setting accelerator, wherein whipping agent can be Sodium dodecylbenzene sulfonate, suds-stabilizing agent can be arachic acid and trolamine, water reducer can be polycarboxylate or wooden calcium, hardening accelerator can be water glass (water glass), and setting accelerator can be calcium chloride.
Beneficial effect.
