Abstract
The invention discloses a preparation technology for pelleting regenerated plastics. The preparation technology for pelleting regenerated plastics comprises the steps of a. charging materials, putting recovered waste plastics and organic solvents into a plastic pelleting machine, carrying out catalytic reaction on the organic solutions and the recovered waste plastics, and softening and recovering waste plastics slowly; b. heating, running a heating device on the plastic pelleting machine, heating the recovered waste plastics and the organic solvents in the plastic pelleting machine, and accelerating the softening speed of the recovered waste plastics; c. extruding, running an extrusion device on the plastic pelleting machine, and extruding the softened recovered waste plastics, thereby obtaining regenerated plastics; and d. granulating, running a grain cutting device on the plastic pelleting machine, and cutting extruded regenerated plastics into grain shapes. According to the invention, the organic solvents are firstly adopted for carrying out catalytic reaction on the waste plastics, and then a physical heating plasticizing reaction is carried out, the softening time of waste plastics is accelerated, meanwhile the organic solvents protect molecular structures in the plastics from being changed, the quality of regenerated plastics is ensured, and the plastics are convenient to be recycled again.
Description
Technical field
The present invention relates to the plastic pellet field, particularly relate to a kind of preparation technology of recycled plastic granulation.
Background technology
Plastic granulator is a kind of automatic forming plant equipment that is used for the waste or used plastics processing and manufacturing is become the graininess regenerated plastics, is applicable to most of common waste or used plastics.Existing plastic granulator is all generally to adopt fully the technology of plasticizing to reach the granulation purpose, so plastic granulator need provide temperature higher than the plastics fusing point with plastic molting, causes the electric energy that consumes for heating of plastic more.The complete plastifying technology that adopts at present be with after the plastic heating melting at crystallization granulation, in this process, what plastics changed is not only profile, even the molecular structure of plastics inner also is changed simultaneously, be that plastics in plasticizing, degraded are to a certain degree occuring fully, make quality and the value of regenerated plastics have a greatly reduced quality, also be unfavorable for later recycling again.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of preparation technology of recycled plastic granulation, and the preparation technology who has solved recycled plastic granulation in the prior art adopts the impact of paying no attention to that plasticizing fully brings.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of preparation technology of recycled plastic granulation is provided, comprises the following steps:
A, charging will be reclaimed waste or used plastics and organic solvent is put into plastic granulator, and described organic solution is carried out catalytic reaction with the recovery waste or used plastics, slowly the softening waste or used plastics that reclaims;
B, heating, the heater on the operation plastic granulator, recovery waste or used plastics and organic solvent in the heating of plastic comminutor, the softening rate of waste or used plastics is reclaimed in quickening;
C, extrude, the pressurizing unit on the operation plastic granulator is extruded the recovery waste or used plastics after softening and is obtained regenerated plastics;
D, granulation, the pellet device on the operation plastic granulator is cut into graininess with the regenerated plastics of extruding.
In a preferred embodiment of the present invention, the particle diameter of described regenerated plastics is 3-6mm.
In a preferred embodiment of the present invention, described organic solvent is trichloride antimony.
In a preferred embodiment of the present invention, the time of described catalytic reaction is 15-35 minute.
The invention has the beneficial effects as follows: the preparation technology of recycled plastic granulation of the present invention; adopt organic solvent first waste or used plastics to be carried out catalytic reaction; carry out again the physical heating plastication; accelerated the softening time of waste or used plastics; organic solvent has protected the molecular structure of plastics inner not changed simultaneously; guaranteed the quality of regenerated plastics, and convenient recycling again.
