Abstract

The invention discloses a recycling scrapped hard polyurethane foam plastic to produce heat insulation plate. Its main feature is that add adhesives and water into the scrapped polyurethane foam plastic after crushed, fill the mould with the mixture after rabbling and maintain determined pressure and temperature for some time, obtain the heat insulation sheets after unmoulding. The invention is of simple technics, low costs and is beneficial for the environment.

Description

Waste hard polyurethane foam is recycled the method that warming plate is made in regeneration
Technical field
The present invention relates to the method that waste hard polyurethane foam is recycled, particularly polyurethane foam plastics regeneration is made a kind of method that reclaims and utilize of warming plate.
Background technology
At present, in producing RPUF product process, can produce the tailing of some, in addition, refrigerator, refrigerator scrap disassemble after, also produce many RPUFs, now, usually all these plastics arbitrarily abandon, landfill or destroy by fire, its maximum shortcoming is to occupy farmland, river course, and, also can cause a large amount of wastes of polyurethane material resource because of burning causes very serious atmosphere pollution, also there is not good solution at present.
Summary of the invention
The purpose of this invention is to provide a kind of waste hard polyurethane foam and recycle the method that warming plate is made in regeneration, this method not only technology is simple, reasonable, and comprehensive utilization of resources rate height, and three-waste free discharge are of value to environmental protection.
The present invention realizes with following technical scheme: a kind of waste hard polyurethane foam is recycled the method for regeneration warming plate, and its technological process is as follows:
Adhesive and water
Useless rigid polyurethane foam plastics → pulverizing → foam beads → apotheca → stir → be weighed into mould → temperature control pressurization → sheet material demoulding
Wherein pulverize: be meant waste hard polyurethane foam is dropped in the disintegrating apparatus, be ground into foam beads; The size of foam beads is: 1～5cm.
Stir: be under the situation that adds adhesive and water, to carry out; The adhesive that adds is polyurethane adhesive and urea-formaldehyde glue; The weight ratio of it and foam beads is 1: 5 ± 1, the water of adding and the weight ratio of foam beads are 1: 37 ± 5
Temperature control pressurization: be meant under the temperature and pressure condition of needs, impel adhesive solidification and moulding between the foam beads.The control temperature is 50～80 degree, and the applied pressure benchmark is that the ratio with the foam beads volume under the normal shape and the volume of warming plate is 3.5: 1.
The sheet material demoulding: be meant and after temperature control pressurization keeps the regular hour, carry out; The time that keeps is with under operating temperature 50～80 degree situations, is 1～2 hour, is 5～8 hours under the normal temperature.
Its good effect is: the heat preservation plate material that utilizes said method to produce, but one-shot forming, also can make slab after, jagsaw, be cut into the sheet material of all size, can be directly used in the laminboard layer of construction wall, permanent or one off houses top, door, wall.Owing to adopted coarse crushing technology, particle size reaches 1～5cm, has kept the distinctive heat preservation and insulation of hard polyurethane ester material so as much as possible.Adopt the foam board good moldability of this method regeneration, vertical and horizontal cutting back foam surface is good, after testing, the cystosepiment compressive strength 〉=200kpa of regeneration, density is 130～145kg/m 3, thermal conductivity factor≤0.045W/ (mk).
Below in conjunction with embodiment the present invention is described in further detail.
Embodiment 1
Take by weighing 50 kilograms disassemble the resulting RPUF of waste refrigerator after, the warming plate of regenerating according to the following steps:
1 with bulk foamed plastics input pulverizer, obtains being of a size of the coarse granule foamed plastics of 1～5cm;
2 place container with the coarse granule foamed plastics, add 4.5 kilograms of polyurethane adhesives and 5 kilograms of Powdered urea-formaldehyde glues after, fully stir, in the process that stirs, with the water of 12 kilograms of atomizers spray;
3 have adhesive and water with adding, and all pack in one long 1 meter, wide 1 meter, high 1.2 meters steel die through well-beaten coarse granule foamed plastics, be furnished with electrical heating wire around the mould, connect power supply, treat that mold surface temperature reaches 60 when spending, and can exert pressure the size of exerting pressure from top to bottom, to be that 3.5: 1 (height of this moment is 40cm) gets final product, kept pressurized state 1～2 hour with the foamed plastics volume of normality and the ratio of the warming plate volume after the pressure;
4 remove applied pressure, after the sheet material demoulding, can saw, cut, cut out, be cut into the heat preservation plate material of all size size shape, and this heat preservation plate material can be used for the battenboard on portable plate door, wall, top, has good heat insulation, deadening.
After testing, the foam density of this warming plate is 130kg/m 3, compressive strength 205kpa, thermal conductivity factor=0041w/ (m.k).
