Abstract
The invention relates to a process for producing regenerated plates, which is characterized in that the process comprises the following steps: 1) mixing polymer materials, crop fiber powder, a modifier and adjuvant additives, and forming a mixture; 2) adding the mixture into a heating device; 3) starting the heating device; 4) smashing the high-temperature mixture, and then sending into a material tube of a single-screw extruder; 5) sending the high-temperature mixture into the material tube of the single-screw extruder; and 6) using the single-screw extruder to extrude the mixture into a mold, carrying out extrusion molding treatment, and then forming the regenerated plates with special shapes. The process has the advantages that the regenerated plates produced by the production process have high hardness and strength, acid and alkali resistance, corrosion resistance, no formaldehyde, difficult deformation, moth proofing property, low cost and good elasticity.
Description
Technical field
The present invention relates to a kind of production technology of regenerated plates.
Background technology
In the prior art, sheet materials such as floor, wallboard generally are to use timber to make, and timber is fewer and feweri at present, and the timber price is more and more higher, and the wood floors price of making is also very high.Existing wood-based planet technology is very high to the timber quality requirements, and the wall tailing of a lot of timber all can not make full use of, and has formed huge waste.Though the composite plate technology can be made composite plate with fillet, its quality but can't be compared with real wooden boards, and needs a large amount of sizing materials in its process, such as urea aldehyde natural gum etc., can produce toxic gases such as formaldehyde, influences human health.Simultaneously, contain not labile in a large number plastics in annual industrial refuse that produces in various countries or the house refuse, environment is caused huge pollution.
Summary of the invention
The purpose of this invention is to provide the regenerated plates technology, can solve effectively that the board cost height, the timber intensity that exist in the prior art are poor, problem such as pollute the environment.The present invention relates to a kind of production technology of regenerated plates, it is characterized in that, comprise the steps:
1) macromolecular material, agronomic crop fibre powder, modifier and promoter additive are mixed the back and form mixture;
2) mixture is added heater;
3) start heater, make the macromolecular material fusing thereby the mixture of macromolecular material and agronomic crop fibre powder heated;
4) hot mixture that mixes is sent in the barrel of single-screw extruder;
5) screw rod of single-screw extruder at the uniform velocity rotates, and mixture is expressed in the mould, becomes the regenerated plates of given shape after handling through being extruded to shape.
Described agronomic crop fibre powder can be sawdust or bamboo fibre powder.The invention has the advantages that: the regenerated plates made from the production technology among the present invention has higher hardness and intensity, and acid and alkali-resistance is anticorrosive, does not contain formaldehyde, and is not yielding, is not afraid of and damages by worms, and with low cost, elasticity is better.
The specific embodiment
A kind of production technology of regenerated plates is characterized in that, comprises the steps:
1) macromolecular material, agronomic crop fibre powder, modifier and promoter additive are mixed the back and form mixture.
Wherein, macromolecular material is various plastics, as PP (polypropylene), PE (polyethylene), PVC (polyvinyl chloride) or ABS resin etc.Described agronomic crop fibre powder also can be sawdust or bamboo fibre powder.
2) mixture is added heater.
Described heater is a banbury, and banbury is a firing equipment commonly used in the chemical industry.
3) start heater, make the macromolecular material fusing thereby the mixture of macromolecular material and agronomic crop fibre powder heated.
Generally speaking, when temperature was elevated to 175 ℃, macromolecular material was promptly fusible, and moisture content in the mixture reduces, and had reduced the influence to the physical property of the products such as sheet material produced that forms owing to moisture content is too high.
4) hot mixture that mixes is sent in the barrel of single-screw extruder.
Single-screw extruder herein also can replace with the extruder of other types, such as plunger type extruder, double-screw type extruder etc.In view of the factors such as discharging speed of hot mixture, select to use the single-screw extruder herein.
5) screw rod of single-screw extruder at the uniform velocity rotates, and mixture is expressed in the mould, becomes the regenerated plates of given shape after handling through being extruded to shape.
The screw rod of single screw extrusion machine at the uniform velocity rotates, heating plastifies mixture once more and mixes to single screw extrusion machine simultaneously, the batch mixing that head by single screw extrusion machine will plastify once more is expressed in the mould, becomes the regenerated plates of given shape after being extruded to shape.
The mechanical strength of mould is very big, can bear bigger pressure, and the mould kind is various, and during production and processing, factory can select different moulds as required, can obtain the sheet material of the different purposes of different-thickness.
Utilize this technology, mixtures such as macromolecular material and agronomic crop fibre powder can fully merge, and functional.Can also suitably reduce the ratio of macromolecular material in the raw material, also be the use amount of regenerated plastics, can further reduce cost.
