Abstract
The present invention relates to a compound pressboard of waste plastics and a production process thereof, which belongs to the technical field of the reproduction and the application of plastic waste. The produced compound pressboard of waste plastics comprises one kind or a plurality of kinds of waste polyethylene, polypropylene, polyvinyl chloride and polystyrene plastics. The production process comprises the steps that packaging bags, bottles of the waste plastics and surplus materials and recovering objects of other products are metered by 5 to 10 kg/m<2> to be flattened and distributed after washed, dried, pulverized, cut and screened; the waste is pressed for 3 to 5 minutes by a presser at the temperature of 80 to 120 DEG C and the pressure intensity of 700 to 800 kg/cm<2> to produce a board; the board is flattened and cut, and then, production is finished. A waste product is changed into a valuable product, and application is extensive. The production process has the advantages of simplicity, easy operation, less energy consumption, no pollution, etc.
Description
The present invention relates to the production method of compound pressboard of waste plastics, 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 technical proposals.
This waste or used plastics compound suppressing, 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, clean up, dry by the fire the part of anhydrating, cut into the sheet strip the waste and old material of one or several plastics that mix in the polyethylene, polypropylene, polyvinyl chloride and the polystyrene plastics that reclaim; Screen out chip, stay material by 5-10kg/m sieve again
2Metering is evenly shakeout cloth, under 80-120 ℃ of temperature conditions, with 700-800kg/cm
2Pressure was implemented die mould 3-5 minute, was 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
With discarded polyethylene packaging bag, composite package film, the bottle waters such as production offal, regenerant of etc.ing clean up, and dry by the fire and remove the water that adheres to, 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
Polyethylene, polypropylene, polyvinyl chloride and production offal, the waters of recycling the waste such as polystyrene plastics soft packaging bag, bottle, woven bag and composite plastic film are cleaned up, and 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.
This compound pressboard of waste plastics not only has strong that wooden plywood has The processability such as degree, density and saw, plane, cutter, nail, but also have good Waterproof, protection against the tide, shock resistance, antistatic, the performance such as fire-retardant, corrosion-resistant; After testing Its technical indicator is
Moisture content:＜7.65%
Draw strength:＞48.1Mpa
Elastic modelling quantity: 3864MPa
Density: 0.91g/cm3
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 (1)
