Hybrid composition including more than two kinds of recycle PCTGs and PC and recycle grinding device

摘要

Disclosed is a recycled polymer hybrid composition and a recycled milling device. The disclosed recycled polymer hybrid composition is characterized in that a first polycyclohexane terephthalate crushed in a pellet form, a second polycyclohexane terephthalate crushed in a pellet form, and a polycarbonate resin are melt-mixed in a compounding method. . The disclosed recycling pulverizing device comprises: a crushing body; An input member disposed at the upper end of the pulverizing body and into which the recycled polymer raw material is injected; A crushing member connected to the injection member and pulverizing the recycled polymer raw material injected into the injection member; A polymer storage member containing a pulverized recycled polymer material that is pulverized and discharged from the pulverizing member of the recycled polymer material, and has a vibrating body configured to vibrate therein so that the pulverized recycled material is evenly distributed; And a storage confirmation member capable of detecting the height at which the recycled polymer pulverized material is stacked in the polymer storage member, wherein the crushing body includes a detection value of detecting the height of the recycled polymer pulverized material in the storage confirmation member. By receiving the transmission, it is possible to control the driving of the vibrating body to match the flatness of the recycled polymeric pulverized material previously designated by the control unit, and at the same time, by checking the amount of the recycled polymeric pulverized material stored in the polymer storage member, When the maximum storage amount of the recycled polymer pulverized material is reached, a control unit is provided to stop driving the pulverizing member. According to the disclosed recycled polymer hybrid composition and recycling pulverizing device, while using conventional polycyclohexane terephthalate as a main material, during injection molding, durability and heat resistance are improved without lowering transparency than before, and release of residual monomers is reduced. A recycled polymer hybrid composition that can be significantly reduced can be provided, and debris or dust generated when the recycled polymer raw material constituting the recycled polymer hybrid composition is pulverized can be prevented from splashing to the outside, and the blade can be easily cleaned. There is an advantage that it is possible to provide a recycling pulverizing device.
