Abstract
The present invention provides a method for utilizing waste foamed plastic, which relates to a processing method for solid waste. Firstly, collected waste foam plastics is cut into sheets and blocks with certain specifications and size dimensions; the waste foam plastics which can not be cut into the sheets and the blocks is crushed into granules; a binding agent and granular foam plastics are proportionally and uniformly stirred and moulded into blocks or sheets; then, the cut sheets and the cut blocks or the moulded sheets and the moulded blocks are filled in space layers among reinforced concrete boards to form composite boards with middle interlayers, or after the granular foam plastics and the binding agent are mixed, the granular foam plastics and the binding agent are directly paved on roofs and in tile hanging board slots, compressed and leveled to form a thermal insulation layer. The method recycles the waste foam plastics, reduces environment pollution and is favourable for the thermal insulation, the acoustic insulation and the energy-saving of houses.
Description
The present invention relates to a kind of processing method of solid waste, particularly its processing is become the method for useful thing, or for improving the method that the concrete slab heat preservation and insulation adopts waste plastics.
Existing various packing foamed plastics, solid waste such as foamed plastics mess-tin (moulding to call useless bubble in the following text) are more and more, become big public hazards of contaminated environment, the general at present landfill disposal that adopts, not only spend human and material resources and financial resources, also will take valuable landfill soil, the useless bubble behind the landfill is moulded and is difficult for degrading; As adopt the useless bubble of burning disposal to mould, and can produce black particle and pernicious gas contaminated environment again, therefore, the bubble that will give up is moulded and is utilized, and it is expensive to turn waste into wealth, and reducing pollution is an important problem.
The number of applying for a patent formerly is that 87102625 the patent of invention disclosed " composite material and the goods thereof of slight cement and light gypsum " and the patent No. are 93207271 utility model patent disclosed " synthetic materials ", though their proportion is all low weight, but their load-bearing property all can not show a candle to reinforced concrete prefabricated board, so, the load-bearing floor that they can not be used as building or directly be layered on the roof, ground floor forms insulating, in addition, their binder dosage is bigger, must guarantee that pulverized foamed plastic can bond mutually, be unfavorable for reducing cost, increase the benefit, be unfavorable for applying.
The objective of the invention is: a kind of method of utilizing of waste foam plastics is provided, and this method is spread cover material material as building with sheet material inserts or roofing with waste foam plastics, makes it reduce contaminated environment, turns waste into wealth.
Technical scheme of the present invention is: the plate, the piece that the waste foam plastics of collecting are cut into the certain specification size earlier, the waste foam plastics that can not cut into plate, piece is broken into granular, mix thoroughly in proportion with cementing agent and granular foam plastics again, be injection molded as block or tabular, plate, the piece that plate, piece or the injection molding that cuts into formed is filled in the middle space of armored concrete slab then, is formed with the composite plate of intermediate course.When what collect is contaminated waste foam plastics, after washing down with clear water or whitewash earlier, is cut into plate again or is broken into granular, after being broken into granular foamed plastics and cementing agent and stirring in proportion, directly be layered in roofing or the tile hanging board slot, pounce on real levelling, form roof insulation, insulation layer; Cementing agent is cement or pitch prill, water glass, lime putty, 107 glue, clay puddle, gypsum; Plate in the composite plate intermediate course, piece seam crossing bond with cementing agent; After foamed plastics grain and cementing agent mix and stir in proportion, cast directly in the reinforced concrete slab intermediate course space, constitute composite plate; The weight ratio of waste foam plastics grain and cement is 1: 3～8.The weight ratio of waste foam plastics grain and pitch prill is 1: 4～8.The weight ratio of lime putty and waste foam plastics grain is 4～10: 1.The weight ratio of waste foam plastics grain and 107 glue is 1: 2～4.The weight ratio of waste foam plastics grain and clay puddle is 1: 3～10.
Major advantage of the present invention is: waste plastic foam can be recycled, reduce and pollute, become Fei Weibao; Be used for building, help heat insulation, the insulation in house, energy-conservation and sound insulation, the sheet material that utilizes this method to make both can be made floor, can make materials for wall again, also can directly be layered on roof or ground floor, formed insulating; The waste foam plastics light weight, coefficient of thermal conductivity is little, and water imbibition is little, is stale-proof, nontoxic, tasteless, and cost is lower.
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1: the plate diagrammatic sketch that waste foam plastics is cut into,
Fig. 2: the piece diagrammatic sketch that waste foam plastics is cut into,
Fig. 3: have steel bar concrete surrounding layer and cementing agent and waste plastics grain to mix the composite plate cut-away view radially of the intermediate course of cast thoroughly.
Fig. 4: the compound plate of steel bar concrete surrounding layer and waste foam plastics plate, piece intermediate course is cut-away view radially.
Among the figure: 1, steel bar concrete lower panel, 2, the plate that forms of waste foam plastics grain and cementing agent injection molding, 3, the steel bar concrete top panel, 4, gluten concrete rib, 5, the piece of waste foam plastics and cementing agent casting, 6, seam.
Embodiment 1:
The method of utilizing of waste foam plastics is plate (see figure 1) or the piece (see figure 2) that the waste foam plastics of will collect cuts into the certain specification size earlier, the concrete size of plate or piece is decided according to the size and the actual needs of waste foam plastics, the waste foam plastics that can not cut into plate or piece is broken into granular, use cementing agent such as cement or pitch prill again, water glass, lime putty, 107 glue and waste plastics grain are mixed thoroughly in proportion, the weight ratio of waste foam plastics grain and cement is 1: 5 or 1: 4, be injection molded as block or tabular, then with the plate that cuts into, the plate that piece or injection molding form, piece is filled in (see figure 4) in the middle space of armored concrete slab, form heat insulation, be incubated and the intermediate course of sound insulation, bond with above-mentioned cementing agent in the seam 6 of plate and plate, can certainly be without cementing agent.
Embodiment 2:
With the difference of embodiment 1 be: after cementing agent and waste plastics grain are mixed thoroughly, directly be layered in roofing or the tile hanging board slot, pounce on real levelling, form roof insulation, insulation layer.
Embodiment 3:
With the difference of embodiment 1 and 2 be: after cementing agent and waste foam plastics grain stir, cast directly over (see figure 3) in the intermediate course space of armored concrete slab, constitute the composite plate of intermediate course, its manufacturing technique method is: the material filling → panel pour concrete that land clearing → brush interleaving agent → reinforcing bar tensioning → frame rib formwork → rib and base plate pour concrete → dismantling inner-side mould of frame rib → cast cementing agent and waste foam plastics grain mix → tear open the outer side form → maintenance of frame rib → shear-steel muscle → play a sheetpile to put.
