Abstract
The invention discloses a kind of method of making special packaging, sheet material with waste EPS foam plastics, finish by following steps: will be with discarded eps foam plastics, be ground into the particle of 1～7mm, obtain reclaiming the eps foam particle after footpath dedusting, drying, fluidization heat treatment, the compression; Or give after issuance of materials mixes in 1～10 to 1 ratio coupling with EPS, wind is delivered in the mould, hot briquetting, and cooling and mould unloading makes product.Again make product, special packaging that quality is up to state standards and sheet material, reclaimed materials blending rate reaches 20%-50%.Solved particle size range, dedusting that waste EPS needs in reclaiming technology, given the issuance of materials matching condition, evenly mixed with EPS, wind send and enter mould to separating of producing, make many key problem in technology difficult problems such as reclaimed materials heat bonding moulding with giving the issuance of materials expansive force.
Description
Technical field
The invention provides and a kind ofly make the method for special packaging, sheet material, belong to the reclaiming and utilizing waste plastics technical field with waste EPS foam plastics.
Background technology
The eps foam plastics are the heat-insulation and heat-preservation, sound insulation of freezer, highway, airfield runway etc., shockproof ideal material, and these products are to be made by the EPS plastic pellet.In the actual production manufacture process, because of special packaging 70% is a disposable product, when producing sheet material, the leftover pieces of 3-5% have been produced, so the annual whole nation produces 500,000 tons of waste EPS foam plastics approximately, be badly in need of a profitable technical method, eliminate the environmental pollution and the recycling that cause, be society and factory's create beneficial result.
Use waste EPS foam plastics, make huge light body special packaging and the insulation benzene plate in market, it is the research and development problem that the home and abroad is attached great importance to, technological difficulties are that waste EPS foam plastics has not had the foaming swelliong power, and pulverizing the back volume increases greatly, and it is big that the space becomes, density diminishes, be difficult for and give that issuance of materials mixes and molding bonded, therefore, the regeneration of waste EPS foam plastics has been subjected to very big restriction.
Summary of the invention
The invention provides and a kind ofly make the method for special packaging, sheet material with waste EPS foam plastics, overcome waste EPS foam plastics in the prior art can not foaming and intumescing and with give hair powder and mix problem with molding bonded.
Technical solution of the present invention is as follows: will be ground into the particle of 1～7mm with discarded eps foam plastics, and obtain reclaiming the eps foam particle after footpath dedusting, drying, fluidization heat treatment, the compression; Also can give after issuance of materials mixes in 1～10 to 1 ratio coupling with EPS, wind is delivered in the mould, hot briquetting, and cooling and mould unloading makes special packaging and insulation benzene plate.
Above-mentioned fluidization heat treatment can adopt steam or 70～100 ℃ of hot-airs to carry out fluidization heat treatment to pulverizing material, makes it to reach the product desired density.
In order to satisfy the fire resistance requirement of product, adopt inorganic combustion inhibitor (phosphide, chloride, hydroxide etc.), organic fire-retardant (carrene, tetrachloro-ethylene, HBCD etc.), bleeding agent (OP, tween etc.) spray reclaim the EPS particle and carry out flame treatment.
By above-mentioned technology method, can make density 14-30kg/m
3Special packaging, density 10-40kg/m
3Insulation benzene plate, product quality all can reach the quality standard of national regulation.
Good effect of the present invention is: can be with discarded eps foam plastics, again make product, waste EPS many key problem in technology difficult problems in reclaiming technology have been solved, as: the particle size range that needs, dedusting, give the issuance of materials matching condition with EPS, evenly mix, wind send and enters the separation of mould to producing, make reclaimed materials heat bonding moulding etc. with giving the issuance of materials expansive force, thereby make reclaimed materials blending utilization rate by existing less than 8% (weight ratio), bring up to 10%-100%, product quality (compression strength＞the 60Kpa that is up to state standards, thermal conductivity factor λ＜0.041w/m3k, oxygen index (OI)＞30), economic benefit improves greatly than existing production method.
The specific embodiment
By following examples the present invention is described for example further, and do not limit the present invention in any way, under the prerequisite that does not deviate from technical solution of the present invention, any change or change that those of ordinary skills that the present invention did are realized easily all will fall within the claim scope of the present invention.
Embodiment 1
With the special-shaped packing of waste EPS leftover pieces (the about 20kg/m of density that reclaims
3) 10 kilograms, pulverize through pulverizer, obtain the reclaimed materials particle of φ 2-6mm, through deduster dedusting, drying, steam treated in the fluidisation heat-treating machine makes the density of pulverizing reclaimed materials EPS particle reach 18kg/m
3, obtain the reclaimed materials that about 9.7kg handles well, give issuance of materials (density 18kg/m with fluidizing drying bed with EPS again
3), 14.6kg, fluidization mixes, and it is stand-by that wind is delivered to storage bin; With compressed air compound is delivered in the die forming machine, logical steam die mould, cooling and mould unloading, the blending utilization rate that obtains reclaimed materials is 30% special packaging, the about 20kg/m of product density
3, compression strength 140Kpa.
Embodiment 2
Get φ 6mm density 5～8kg/m
3Reclaimed materials particle 4 liters, spray 15% magnesium chloride brine 300ml, put into mould after the drying, logical steam heat was handled 1 minute, after volume compression 80%, obtaining density is 35～40kg/m
3, compression strength greater than 60Kpa, oxygen index (OI) greater than 30 product of the present invention.
Embodiment 3
With discarded EPS sheet material leftover pieces (the about 18kg/m of density that reclaims
3) 20 kilograms, with pulverizer pulverize, screening, obtain the reclaimed materials particle of φ 1-6mm, after the dust removal machine dedusting, 15% ammonium chloride of per 500 gram material spray 30ml, 8% tetrachloro-ethylene are with 1 to 1 aqueous solution that mixes, and heat treatment in the fluidisation heat-treating machine, drying obtain 16kg/m
319 kilograms of the reclaimed materials that arrives give issuance of materials (density 16kg/m with EPS
3) in proportion (reclaimed materials 40% gives issuance of materials 60%) carry out fluidization and mix, it is stand-by that wind is delivered to feed bin.Time spent is delivered to loading hopper with compound wind, sends into again in the big plate machine cavity, and steam molding, cooling and mould unloading cuts behind the dryness finalization, makes the plate product that needs size, the about 18kg/m of density
3, λ 0.040w/m
3K, oxygen index (OI)＞30.
