Embodiment 1

[0012] A. Raw material processing: Sorting-crushing-cleaning the collected waste car PP plastic bumpers to remove impurities and dust for later use;

[0013] B. Feed processing: Put the spare scrap bumper broken material into the special paint remover mixer, pour about 1 / 5 of the paint remover, and stir for 10-20 minutes, the paint on the flakes will fall off in powder form shutdown;

[0014] C. Unloading and sieving: sieve the fragments of the stirred and stripped paint, and remove the dust of the paint flakes;

[0015] D. Unloading and packaging: The cleaned flakes can be directly fixed at 25kg / pack or 1 ton / package, and become PP bumper paint stripping recycling materials.

Embodiment 2

[0017] Ingredients modification: Test the clean flakes to obtain the measured values ​​such as melt index, density, impact strength, tensile strength, elongation at break, etc., and then add the following additives according to the measured data for modification and mixing:

[0018] PP bumper net sheet 100 copies

[0019] Compatible toughening agent 5-15 parts

[0020] Modified granulation: The mixed material is granulated on the machine to become a special material for automobile bumper that meets or is similar to the index of PP plastic bumper.

Abstract

The invention relates to a processing modification method for depainting waste plastics, in particular to a method for depainting and modifying a waste automobile PP plastic bumper into a special material. By adding a proper amount of compatible toughening modifier, the modified PP plastic bumper can reach or approximate to the technical index of a brand new material, and becomes the special material for the automobile PP plastic bumper according with the national standard.

Description

technical field [0001] The invention relates to a processing modification method for paint removal of waste plastics, in particular to a method for modification of waste automobile PP plastic bumpers into special materials by paint removal. Background technique [0002] As everyone knows, the paint stripping of the existing plastic bumper of scrap automobiles is a difficult problem in recycled plastics. Because the traditional paint stripping method is time-consuming and labor-intensive, and is accompanied by secondary pollution that causes environmental risks, the crushed or granulated materials that cannot be stripped are of low quality and limited in use. How to reduce costs and improve quality has become a difficult problem in the waste plastic bumper processing industry. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned background technology, to realize the good paint stripping of the PP pla...
