Abstract
The invention relates to the field of a plastic product, and in particular relates to a manufacturing method of a plastic material. The manufacturing method comprises the steps of screening plastic particles, and drying the screened plastic particles; heating the dried plastic practices for the first time in order to heat the practices to be liquid; squeezing out the liquid obtained in the first heating treatment; putting the liquid into a micro-vibrating device, and carrying out precipitation separation for removing water; calendaring the liquid from which the water is removed to be a semi-finished product; heating the semi-finished product for the second time, and then carrying out plastic molding. The manufacturing method of the plastic material is realized by a plurality of steps, the prepared plastic material contains few impurities, the water is greatly reduced, and the plastic material can be recycled, so that the manufacturing method is more environment-friendly.
Description
Technical field
The present invention relates to field of plastic products, relate in particular to a kind of preparation method of plastic material.
Background technology
Current plastic material is for the production of diversified product, different products is also different to the requirement of plastic raw materials, polyester is a kind of engineering plastics of function admirable, just very popular since coming out, output increases year by year, and range of application also constantly enlarges, according to estimates, Polyester production capacity is about 1200t/a at present, wherein most of for weaving, only has the raw materials for production of sub-fraction as polyester bottles and packaging film; In recent years, the Application and Development of non-polyester is subject to the attention of countries in the world gradually, especially developed country to the input of non-polyester apparently higher than fiber-grade polyester, the growth rate of capacity and output also obviously is greater than fiber-grade polyester, polyester bottles is as the main application of non-polyester, occupy in social life critical role, bottle-grade polyester chip is divided into copolymerization, homopolymerization two classes, according to different purposes, can be divided into for mineral water bottle, carbonated drink bottle, other food containers and packaging material, but existing bottle level polyester has larger pollution to environment.
Summary of the invention
The object of the invention is to propose a kind of preparation method of plastic material, can make the plastic uptake product with environmental-protection function for article container and packaging material.
For reaching this purpose, the present invention by the following technical solutions:
A kind of preparation method of plastic material comprises:
Step a, screening plastic pellet, carry out drying by the plastic pellet after screening and process;
Step b, dried plastic pellet is heated for the first time to liquid condition;
Step c, extrude the liquid after heating for the first time;
Steps d, liquid is put into to microseism swing device and carry out precipitate and separate, remove moisture;
Step e, the liquid that will remove after moisture are rolled into semi-finished product;
Step f, described semi-finished product are heated for the second time, and plastics sucking moulding.
Wherein, microseism is swung device and is dragged by motor, can accelerate separating of plastic liquid and moisture.
Wherein, add for the first time gentleness and heat for the second time, temperature all is controlled at 250-300 ℃.
Wherein, semi-finished product are the transparent plastic sheeting of sheet.
Wherein, half-finished thickness is between 0.1-1.2mm.
Wherein, plastic pellet is polyester material.
Further, plastic pellet is the bottle-grade polyester chip material.
Beneficial effect of the present invention is: a kind of preparation method of plastic material comprises: the screening plastic pellet, carry out drying by the plastic pellet after screening and process; Dried plastic pellet is heated for the first time to liquid condition; Extrude the liquid after heating for the first time; Liquid is put into to microseism and swing device and carry out precipitate and separate, remove moisture; Liquid after removal moisture is rolled into to semi-finished product; Described semi-finished product are heated for the second time, and plastics sucking moulding, realize the preparation method of plastic material in the present invention by a plurality of steps, the plastic material impurity, the moisture that prepare are reduced in a large number, recoverable, have more environmental-protection function.
The accompanying drawing explanation
Fig. 1 is preparation method's flow chart of a kind of plastic material of providing of the specific embodiment of the invention.
The specific embodiment
Further illustrate technical scheme of the present invention below in conjunction with Fig. 1 and by the specific embodiment.
Fig. 1 is preparation method's flow chart of a kind of plastic material of providing of the specific embodiment of the invention.
A kind of preparation method of plastic material comprises:
Step a, screening plastic pellet, carry out drying by the plastic pellet after screening and process;
Step b, dried plastic pellet is heated for the first time to liquid condition;
Step c, extrude the liquid after heating for the first time;
Steps d, liquid is put into to microseism swing device and carry out precipitate and separate, remove moisture;
Step e, the liquid that will remove after moisture are rolled into semi-finished product;
Step f, described semi-finished product are heated for the second time, and plastics sucking moulding.
In the present embodiment, the plastic pellet that plastic raw materials is polyester slice, or the leftover pieces of shaped article, or the mixture of leftover pieces and plastic pellet, the process of plastic pellet screening is removed to impurity and some underproof raw materials exactly, the plastic pellet drying is a heat transfer, the physical process of mass transfer, removing of its moisture can be divided into two kinds: plastic pellet adsorption and interior molecules are in conjunction with water, the former more easily removes, and the latter permeates more difficult removing in plastic pellet, while only having the steam partial pressure difference of and surperficial existence inner when plastic pellet, and under time enough, the internal junction Heshui just can be diffused into the plastic pellet surface and then flash to dry hot-air and take out of.
In the present embodiment, microseism is swung device and is dragged by motor, can accelerate separating of plastic liquid and moisture, and microseism is swung device and utilized the proportion difference of plastic liquid and moisture to carry out aids precipitation to it to separate, plastic liquid is purified.
In the present embodiment, add for the first time gentleness and heat for the second time, temperature all is controlled at 250-300 ℃.
In the present embodiment, semi-finished product are the transparent plastic sheeting of sheet.
In the present embodiment, half-finished thickness is between 0.1-1.2mm.
In the present embodiment, plastic pellet is polyester material.
As another kind of embodiment, plastic pellet is the bottle-grade polyester chip material.
The foregoing is only the specific embodiment of the present invention, these are described is in order to explain principle of the present invention, and can not take any interpretation of structure as limiting the scope of the invention.Explanation based on herein, those skilled in the art does not need to pay performing creative labour can associate other specific implementation method of the present invention, within these structures all will fall into protection scope of the present invention.
