Abstract

PURPOSE: A method for managing recycling of a useless bumper for a car is provided to use a useless bumper as the recycling resin by removing paints coated on the external face of the bumper after collecting the useless bumper. CONSTITUTION: In the method for managing recycling of the useless bumper for the car, a separator(6) is included. The separator(6) includes a frame(8), a rotary tub(10), an axial rod(12), stirring wings(14), a hole(16) for throwing into. The rotary tub(10) is composed by the motor on the frame(8). Many stirring wings(14) are installed on the axial rod(12), which goes through the rotary tub(10). The hole(16) for throwing into is formed in the rotary tub(10) to throw in the mixed materials or take out them. The stirring wings(14) improve efficiency of detachment of paints by making grinded materials rub with one another.

Description

자동차용 폐범퍼의 재활용 처리방법Recycling method of waste bumper for automobile

본 발명은 자동차용 폐범퍼를 수거하여 재활용할 수 있도록 한 자동차용 폐범퍼의 재활용 처리방법에 관한 것이다.The present invention relates to a recycling method of a waste bumper for a vehicle to collect and recycle the waste bumper for a vehicle.

자동차용 범퍼는 기능상 물성이 우수한 수지(복합PP. XENOY)를 사용하고 있으며, 이러한 수지는 재활용성이 매우 높은 수지임에도 지금까지는 효율적인 재활용이 이루어지지 못하고 있는 실정이다.Bumpers for automobiles use resins with excellent physical properties (composite PP. XENOY), and even though these resins are highly recyclable resins, they have not been efficiently recycled until now.

즉 일반적으로 자동차용 폐범퍼가 처리되고 있는 실정을 보면 수거후 소각처리 하거나 수거된 범퍼를 분쇄한 다음 범퍼외면에 도장된 페인트를 제거하지 않고 저급의 재활용 수지로 사용되고 있는 실정이다.In other words, in the situation where the automobile waste bumper is being processed, it is used as a low-grade recycled resin without incineration after collection or after crushing the collected bumper and removing paint painted on the outer surface of the bumper.

이는 지금까지 범퍼 외면에 도장된 페인트의 효율적인 제거를 위한 기술이 제공된 것이 없었기 때문이며, 이러한 실정 때문에 물성이 우수한 고품질의 수지를 재활용하지 못하게 되고, 따라서 자원의 낭비는 물론 경제적으로도 많은 낭비를 초래하게 될 뿐아니라 환경 오염차원에서도 심각한 문제성이 야기되고 있는 실정이다.This is because no technology has been provided for efficient removal of paint painted on the outer surface of the bumper, and this situation prevents the recycling of high quality resins having excellent physical properties, thus causing a waste of resources as well as economic waste. Not only that, but also serious problems are caused in terms of environmental pollution.

본 발명은 이러한 종래의 제반 문제점들을 시정하고자 폐범퍼를 수거한 다음 분쇄하고, 상기 분쇄물을 처리하여 범퍼 외면에 도장된 페인트를 제거하므로서 수지로만 된 분쇄물을 얻고, 상기 분쇄물을 재생칩화하여 재활용할 수 있도록 한 것이다.The present invention collects and then pulverizes the waste bumper to correct these problems, and obtains a pulverized resin only by removing the paint coated on the outer surface of the bumper by treating the pulverized product, and recycling the pulverized product into chips. It is intended to be recycled.

제1도는 폐범퍼의 정면도.1 is a front view of the waste bumper.

제2도는 폐범퍼를 분쇄한 분쇄물의 상태도.2 is a state of the pulverized product pulverized the waste bumper.

제3도는 본 발명에 사용되는 분리기의 구성도.3 is a block diagram of a separator used in the present invention.

이하, 본 발명의 바람직한 실시예를 첨부도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

폐범퍼(2)를 분리수거 한 다음 표면을 깨끗이 세척하고, 세척된 폐범퍼(2)를 분쇄기를 통하여 분쇄하되, 분쇄물(4)의 크기가 20mm 정도되게 분쇄한다.After the waste bumper (2) is collected and separated, the surface is washed cleanly, and the washed waste bumper (2) is pulverized through a grinder, but the size of the pulverized product (4) is pulverized to about 20 mm.

상기에서 분쇄된 분쇄물(4)을 분리기(6)내에 처리제와 함께 적절한 비율로 투입한 다음 분리기를 작동시켜 분쇄물(4)에 도장된 페인트를 분리 시키게 되고, 페인트가 분리된 분쇄물(4)을 세척조에 투입하여 세척하고, 세척된 분쇄물(4)을 다시 압출기에 투입 한 다음 용융 압출 하면서 절단하여 재생칩을 제조하고, 상기 재생칩을 이용하여 범퍼의 성형에 재사용하거나 필요한 용도로 폭넓게 사용하게 된다.The pulverized powder 4 pulverized above is introduced into the separator 6 together with the treatment agent at an appropriate ratio, and then the separator is operated to separate the paint coated on the pulverized product 4, and the pulverized powder 4 is separated from the paint. ) Is put into a washing tank, washed, and the washed crushed product (4) is put into the extruder again and cut while melt extruding to produce a recycled chip, and the recycled chip can be reused for molding a bumper or widely used for necessary purposes. Will be used.

이때 폐범퍼(2)에 도장된 페인트를 제거하기 위한 분리기(6), 처리제, 및 처리조건은 다음과 같다.At this time, the separator 6 for removing the paint painted on the waste bumper 2, the treatment agent, and the treatment conditions are as follows.

먼저 분리기(6)의 구성은 다음과 같다.First, the structure of the separator 6 is as follows.

즉 제3도에서와 같이 프레임(8)상에 모터(7M)에 의해 회전하는 회전통체(10)를 구성하고, 상기 회전통체(10)를 관통하는 축봉(12)상에 다수의 교반날개(14)를 용접설치하고, 회전통계(10)에는 분쇄물(4)을 투입하거나 꺼집어내기 위한 투입구(16)가 구성되어 있다.That is, as shown in FIG. 3, a rotating cylinder 10 rotating on the frame 8 by a motor 7M is formed, and a plurality of stirring vanes (3) are formed on the shaft 12 passing through the rotating cylinder 10. 14) is welded and the rotation statistics 10 is provided with an inlet 16 for injecting or taking out the pulverized material (4).

상기 회전통체(10)내에 분쇄물(4)과 함께 투입되는 처리제는 염화메틸렌이며, 분쇄물(4)과 염화 메틸렌의 투입비율은 10 : 1, 즉 분쇄물 약 200kg에 염화메틸렌 약 20kg의 비율이 적합하다.The treating agent introduced together with the pulverized product 4 in the rotary cylinder 10 is methylene chloride, and the ratio of the pulverized product 4 and methylene chloride is 10: 1, that is, the ratio of about 20 kg of methylene chloride to about 200 kg of the pulverized product. This is suitable.

이러한 조건으로 회전통제(10)내에 분쇄물(4)과 처리제가 투입되면 투입구(16)를 밀폐한 다음 모터(M)를 구동시켜 회전통체(10)를 회전시키면서 약 60분 정도 처리하게 되면, 분쇄물(4)표면에 도장된 페인트는 처리제와 화학적 반응을 일으키면서 분쇄물로부터 분리된다.When the pulverized product 4 and the processing agent are introduced into the rotary control 10 under these conditions, the injection port 16 is closed, and then the motor M is driven to process about 60 minutes while rotating the rotary cylinder 10. Paint applied to the surface of the pulverized product 4 is separated from the pulverized product by causing a chemical reaction with the treatment agent.

이때 축봉(12)외면에 구성된 교반 날개(14)는 분쇄물 끼리 서로 충분히 마찰 되게 하여 페인트의 박리 효과를 더욱 증진 시키기 위한 것이다.At this time, the stirring blades 14 formed on the outer surface of the shaft 12 are to be sufficiently rubbed with each other the pulverized powder to further enhance the peeling effect of the paint.

상기에서와 같이 처리하여 분쇄물(4)로부터 페인트의 박리가 완료되는 회전통제(10)로부터 분쇄물과 처리제를 분리한 다음, 분쇄물은 위에서 설명한 바와 같이 세척하여 압출기로 공급 재생칩화 하게 되고, 처리제는 정제처리 한 다음 재사용케 함으로써 수질오염을 최소화하도록 한다.After processing as described above to separate the pulverized product and the processing agent from the rotary control 10 to complete the peeling of the paint from the pulverized product (4), the pulverized product is washed as described above to be fed to the regenerated chip feed to the extruder, Treating agents should be purified and reused to minimize water pollution.

이와 같은 방법으로 폐범퍼에 도장된 페인트를 완전히 제거한 다음 물성이 우수한 범퍼용 수지(복합PP. XENOY)만 분리하여 재활용토록 하므로서, 소각에 따른 환경오염을 줄일 뿐아니라, 고가의 자원을 재활용토록 하므로서 재료의 수입에 따른 많은 경비를 절감할 수 있게되는 등의 효과가 있는 것이다.In this way, the paint applied to the waste bumper is completely removed, and only the bumper resin (composite PP. XENOY) with excellent physical properties is separated and recycled, thereby reducing environmental pollution from incineration and recycling expensive resources. It will be able to save a lot of expenses due to the import of materials.
