Abstract
The invention belongs to the technical field of heat-preserving building materials, and specifically relates to a preparation process for an adhesive powder polyphenyl granule heat-preserving slurry by using waste polystyrene foamed plastic. The process comprises the following steps: crushing recycled waste polystyrene foamed plastic through a crusher so as to obtain regenerated polyphenyl granules; and adding water into a stirrer, then adding cement, adhesive powder and an auxiliary agent, carrying out uniform mixing under stirring through the stirrer, after stirring, adding polyphenyl granules, and continuing stirring and carrying out uniform mixing so as to obtain a finished product. The preparation process provided by the invention has the advantages of simple process, safety, environmental protection, utilization and regeneration of wastes, low thermal conductivity, good durability and strong weather resistance.
Description
Technical field
The invention belongs to heat-insulating construction material technical field, especially relate to the technique that a kind of waste polystyrene foamed plastics prepares adhesive powder-polystyrene granule thermal insulation mortar.
Background technology
Polystyrene foam plastics (EPS) is widely used in the packaging of building thermal insulation material and household electrical appliance, instrument and meter, artware and other fragile goods and the packaging of fast food. The production and cutting process of polystyrene foam plastics can produce many leftover pieces, and the polystyrene foam plastics for packing is all single use, it is finished and has just become garbage, owing to being difficult to decompose under natural environment, they are abandoned with rubbish and will result in serious environmental pollution. Along with the increase day by day of foam plastics consumption, polluting also day by day serious, for solving its pollution to environment, recycling is the most important measure of harmless to environment.
Simultaneously, the building heat preservation system that current adhesive polystyrene granule heat-insulating mortar is heat-insulation layer occupies considerable proportion in industry with civil buildings, but the adhesive polystyrene granule heat-insulating mortar of the insulation sold on the market is low big with water absorption rate because of the granular polystyrene intensity used, and causes that product exists the defects such as linear shrinkage is big, coefficient of softing is low.
Summary two aspect problem, it is very necessary for inventing a kind of energy-conserving profit waste, enhancing product performance and reduce the novel polyphenyl granule thermal insulation slurry of product cost.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that regeneration that a kind of technique is simple, safety and environmental protection, profit are given up, the technique utilizing waste polystyrene foamed plastics to prepare adhesive powder-polystyrene granule thermal insulation mortar that heat conductivity is low, good endurance, weatherability are strong.
A kind of waste polystyrene foamed plastics of the present invention prepares the technique of adhesive powder-polystyrene granule thermal insulation mortar, comprises the following steps:
(1) being pulverized by pulverizer by the waste polystyrene foamed plastics of recovery, as lightweight aggregate and the reworked material of insulation material, the course of processing need to control the granularity of discarded granular polystyrene and unit weight well, and bulk density is less than 20kg/m3, the particle diameter granule less than 5mm more than 90%, should obtain reclaimed grain;
(2) by following portions by weight proportioning feeding: granular polystyrene 4.5-25 part of 5-80 order, cement 60-90 part, rubber powder 0.5-2.5 part, auxiliary agent 0-5 part, water 70-220 part;
(3) mechanical system should be adopted to stir the component of above-mentioned parts by weight, in blender, first add water, add cement, rubber powder and auxiliary agent to be stirred by blender, add granular polystyrene after stirring 3-4 minute and continue to stir 3-4 minute to uniformly, namely obtain finished product.
Described waste polystyrene foamed plastics is tailing or the waste packaging materials of factory.
Described cement is portland cement, sulpho-aluminous cement or magnesia oxychloride cement.
Described rubber powder is calcium hydroxide, flyash and indefinite form silicon dioxide.
Described auxiliary agent is hydroxypropyl methyl cellulose.
Advantages of the present invention and having the benefit effect that
(1) utilize that the granular polystyrene that waste polystyrene foamed plastics reclaims maintains feature and the light weight of primary granular polystyrene, thermal conductivity is little, water absorption rate is low, also add granular-grade prepare, multi-angular, be prone to be wrapped up by slurry, have good workability, the advantage not available for former granular polystyrene such as cheap. Owing to its shape, apparent condition and grating all there occurs change, reclaimed grain profile is as the criterion ball-type or broken stone type, rough surface and part surface opening, cement slurry easily enters hole, is conducive to cohering with cement matrix, and reclaimed grain is made up of multiple particles, granular-grade prepares, can forming close-packed structure, slurry demand is few, and these characteristics make reclaimed grain compound insulating material have good serviceability and workability.
(2) rubber powder of granular polystyrene selects the multiple inorganic material such as calcium hydroxide, flyash and indefinite form silicon dioxide, it is to avoid the problems such as cement density is big, Gypsum Fibrosum is not water-fast, and thermal stability is very excellent.
(3) the 90% of glue powder polyphenyl granule insulating material cumulative volume is to utilize the polystyrene the like waste reclaimed to make, and real achieves the useless regeneration of profit. Glue powder polyphenyl granule insulating material has purified environment while building novel building, is a kind of good ecological ideas building materials.
(4) present invention can carry out the recovery pelletize work of a large amount of waste polystyrene foamed plastics, and time saving and energy saving, work efficiency is high, and the cost of equipment is low, and preparation method is simple.
