Abstract

The present invention belongs to the technological field of re-using waste plastics,wWaste bags, bottles and leftover of polyethylene, polypropylene, polyvinyl chloride and polystyrene, after being washed, dried, crushed and sieved, are spread in the amount of 5-10 Kg/sq m and pressed at 700-800 Kg/sq cm pressure and 80-120 deg. c for 3-5 min into pressboard, which is finally finished. The present invention changes waste into useful material with wide use.

Description

Compound pressboard of waste plastics and production method thereof

The present invention relates to compound pressboard of waste plastics and production method thereof, belong to plastic wastes and make applied technical field again.

At present, along with the particularly development of plastics industry and the raising of living standards of the people of modern industry, disposable plastics and plastic coating, paper plastic combined package thing are widely applied.The discarded object of a large amount of plastic foils, polybag, bottle, woven bag and various plastic coating, compound package material goods has constituted the public hazards to social environment.Because these plastic refuses are difficult to degraded, become scattered about nature for a long time, seriously jeopardize existent environment of people, constitute social concern seriously.Though the existing multiplex technique that reclaims all has selectivity and the bigger defective of limitation to waste or used plastics.And technical sophistication, regeneration cost make a large amount of waste or used plastics be difficult to thorough removing than problems such as height.

The objective of the invention is to turn waste into wealth provides a kind of classification that need not, and mixes assembly arbitrarily, can multiple plastic refuse be base material, suppresses compound pressboard of waste plastics and production method thereof, offers to society, brings benefit to the mankind.

Task of the present invention realizes by following technology and scheme.

This compound pressboard of waste plastics, one or several the waste and old material compacting that includes polyethylene, polypropylene, polyvinyl chloride, polystyrene plastics constitutes.

Its production method comprises that following processing step forms.

At first the polyethylene, polypropylene, polyvinyl chloride and the polystyrene that reclaim are moulded the waste and old material of one or several plastics that mix in the section, cleaned up, dry by the fire the part of anhydrating; Cut into the sheet strip; Screen out chip, stay material by 5-10kg/m sieve again 2Cloth is evenly shakeout in metering; Under 80-120 ℃ of temperature conditions, with 700-800kg/cm 2Pressure was implemented die mould 3-5 minute.Be pressed into sheet material; Sheet material is carried out smooth processing and cuts into regular plate, promptly make the present invention's compound pressboard of waste plastics.

The present invention will be described further in conjunction with the embodiments

Embodiment 1:

Waters such as productions offal, regenerant such as discarded polyethylene packaging bag, composite package film, bottle are cleaned up, dry by the fire and remove the water that attaches, cut into the sheet stick, screen out chip, sieve and stay material by 5kg/m through screening through Material disintegrator 2Metering is evenly shakeout cloth and is delivered to press.Under 80 ℃ of temperature, with 700kg/cm 2Pressure is implemented die mould, promptly makes sheet material through 3 fens clock times, and carrying out the thickness that smooth side cut forms rule again is the plate of 5mm, is compound pressboard of waste plastics.

Embodiment 2:

With polyethylene, polypropylene, polyvinyl chloride and polystyrene plastics soft packaging bag, bottle, woven bag, and production offal, the water of recycling the waste such as composite plastic film clean up, row is dry again; Screen out fines after cutting into the sheet stick, the residues material is pressed 10kg/M 2Measure, shakeout cloth; To press under 120 ℃ of temperature conditions, with 800kg/cm 2Pressure is implemented die mould, forms sheet material through compacting in 5 minutes, and smooth again side cut forms the thick regular plate of 10mm, is the present invention's compound pressboard of waste plastics.

Intensity, density that this compound pressboard of waste plastics not only has wooden plywood and had, and processability such as saw, plane, cutter, nail, but also have excellent waterproof, protection against the tide, shock resistance, antistatic, performance such as fire-retardant, corrosion-resistant; Its technical indicator is after testing:

Moisture content:<7.65%

Draw strength:>48.1Mpa;

Elastic modelling quantity: 3864MPa;

Density: 0.91g/cm 3

Front screw grip force: 1350N;

Thickness swelling rate: 5.04%.

Owing to have above-mentioned premium properties, and can overlay wood by coated with resins, surface, mould deep processing such as decorative faced and handle, can be widely used in building, chemical industry finishing, car and boat and furniture aspect material; Be twice laid, turn waste into wealth, with low cost, draw materials extensively, have higher utility.

Its production method belongs to Physical Processing, have that technology is simple, power consumption less, pollution-free, easy operating and mass industrialized production, production efficiency and yield rate advantages of higher.

Claims (2)

1, a kind of compound pressboard of waste plastics is characterized in that: one or several the waste and old material compacting that this plate includes polyethylene, polypropylene, polyvinyl chloride, polystyrene plastics constitutes.
2, a kind of production method of compound pressboard of waste plastics, form by following processing step:
2.1, in the polyethylene, polypropylene, polyvinyl chloride and the polystyrene plastics that reclaim one or several mixed waste and old material clean up, the dry baking part of anhydrating,
2.2, cut into the sheet stick,
2.3, screen out chip, stay material by 5-10kg/m sieve 2Cloth is evenly shakeout in metering,
2.4, under 80-120 ℃ of temperature conditions, with 700-800kg/Cm 2Pressure was implemented die mould 3-5 minute, was pressed into sheet material,
2.5, with pressboard smooth cut into the rule plate.Promptly make compound pressboard of waste plastics.
