Abstract
The invention discloses a method for recycling industrial recycled waste plastics, which comprises the following steps of S1, mincing the waste plastics through a mincing machine, cutting the waste plastics into strip-shaped structures before mincing, and then mincing the strip-shaped structures, wherein the size of the minced plastics is not more than 5 cm; s2: putting the crushed plastic into a hot pressing mechanism for hot pressing; s3: melting the plastic subjected to the hot pressing treatment at high temperature, adding a modifier into a high-temperature melting machine, wherein the modifier is a flame retardant and a filler, and stirring while adding; s4: the molten plastic added with the modifier is put into a plastic extruder, the plastic is extruded into a die to be remanufactured, and the die is cooled to room temperature to prepare a new product.
Description
Technical Field
The invention belongs to the field of waste treatment, and particularly relates to a method for recycling post-industrial recycled waste plastic.
Background
The quantity of waste plastics generated in industrial production is huge, and improper treatment of the waste plastics not only pollutes the environment, but also takes decades or even hundreds of years for natural degradation. It is therefore necessary to recycle these industrial waste plastics. Since the invention of plastics, plastic products are closely related to the life of people, and the plastic product industry is rapidly developed. Moreover, with the wide application of plastic products in daily life and the demand for plastic products in various fields of national economy, a large amount of plastic is produced and utilized. The mass production and use of plastic products has promoted the development of the plastic product industry on the one hand and brought a large amount of waste plastics on the other hand.
Disclosure of Invention
The present invention is directed to overcoming the above-mentioned deficiencies of the prior art and providing a method for recycling waste plastics for post-industrial recycling.
The purpose of the invention can be realized by the following technical scheme:
a method for recycling post-industrial recycled waste plastic, comprising the steps of:
s1, the waste plastics are crushed by a crusher, the waste plastics are cut into strip-shaped structures before being crushed, the strip-shaped structures are crushed again, and the size of the crushed plastics is not more than 5 cm;
s2: the plastic after being crushed is put into a hot-pressing mechanism for hot-pressing treatment after being crushed into one piece,
s3: melting the plastic subjected to the hot pressing treatment at high temperature, adding a modifier into a high-temperature melting machine, wherein the modifier is a flame retardant and a filler, and stirring while adding;
s4: and (3) putting the molten plastic added with the modifier into a plastic extruder, extruding the plastic into a die for remanufacturing, and cooling to room temperature to obtain a new product.
The invention has the beneficial effects that:
the plastic recovery method is simple, and can also prepare new finished products with high recovery rate.
Detailed Description
The technical scheme of the invention is further described as follows:
a method for recycling post-industrial recycled waste plastic, comprising the steps of:
s1, the waste plastics are crushed by a crusher, the waste plastics are cut into strip-shaped structures before being crushed, the strip-shaped structures are crushed again, and the size of the crushed plastics is not more than 5 cm;
s2: the plastic after being crushed is put into a hot-pressing mechanism for hot-pressing treatment after being crushed into one piece,
s3: melting the plastic subjected to the hot pressing treatment at high temperature, adding a modifier into a high-temperature melting machine, wherein the modifier is a flame retardant and a filler, and stirring while adding;
s4: and (3) putting the molten plastic added with the modifier into a plastic extruder, extruding the plastic into a die for remanufacturing, and cooling to room temperature to obtain a new product.
Finally, it should be noted that:
the method may be carried out and its application may be carried out by those skilled in the art with reference to the disclosure herein, and it is expressly intended that all such alternatives and modifications as would be apparent to those skilled in the art are deemed to be included within the invention. While the method and application of the present invention have been described in terms of preferred embodiments, it will be apparent to those of ordinary skill in the art that variations and modifications in the method and application of the invention as described herein may be made and equivalents employed without departing from the spirit and scope of the invention.
Although the present invention has been described in detail with reference to the above embodiments, it should be understood by those skilled in the art that: modifications and equivalents may be made thereto without departing from the spirit and scope of the invention, and it is intended that the appended claims cover such modifications and equivalents as fall within the true spirit and scope of the invention.
