METHOD FOR RECYCLING WASTE THERMOPLASTIC MATERIALS AND USING THIS RECYCLED THERMOPLASTIC IN COMPOSITE MATERIAL PRODUCTION

摘要

This invention is related to a method for production of high strength and low cost thermoplastic composite materials by processing and treating waste plastic materials with some minerals. The object of the invention is to embody a recycling method wherein it contains high amounts of additives and therefore composite materials with high strength properties are obtained. Another object of the invention is to embody a recycling method wherein high amounts of additives are used in the production and the machines used in the production are not damaged.

主权项

1. A method for recycling waste plastic materials and using this recycled plastic in composite material production, characterized in that it comprises the steps of;
Releasing a number of types of compressed thermoplastic waste materials by feeding into a bale opening machine (110), Feeding the waste plastic materials into a separation unit and in there separation from rocks, earth, sand and other coarse foreign materials (120), Feeding the waste plastic material into the cutting machine, cutting the waste plastic material into small pieces through high speed blades and at the same time washing by injecting water into the machine (130), Feeding the waste plastic materials cut into small pieces to a muddy water separation machine and separation of slimed material from the muddy water by centrifugal forces (140), Transferring the material into a pool filled with water, rinsing in there and at the same time precipitation of sand and other heavy materials that may have left on it (150), Transferring the material into the organic contamination separation machine and here cleaning of the oil and other organic foreign materials on the material that can not be removed in the previous processes by centrifugal forces (160), Transferring the material to the water separation machine and there separating the water and moisture on the material by centrifugal forces (170), Storing the material by transferring to storage silos (180), Transferring the material into the drying machine and here drying the material by heating and at the same time powdering it by crinkling for easy feeding to machines in the future processes (190), Storing the dried and crinkled material by transferring to storage silos (200), Transferring the material to the horizontal reactor (210), Heating the material in the horizontal reactor under pressure up to 350° C. temperature (220), Adding the painter and the compatibilizer chemical materials to the material heated in the horizontal reactor through a side feeding unit (230), Adding mineral materials, through another side feeding unit, to the material in which painter and compatibilizer chemical materials have been added and which is being heated in the horizontal reactor (240), Heating the plastic material until linear links are broken, cross links are established and materials are relinked to each other at the molecular level (250), Immediately pouring the melted composite material exiting from the horizontal reactor into the molds before it cools down and cooled under pressure by compression inside the molds.
