Embodiment 1

[0012] The processing modifier of the present invention is prepared by the following components and parts by weight: When detecting the melt flow index M1 of the waste hollow material of polypropylene = 0.5~0.8, take 0.5 part of chlorinated polyethylene and 8 parts of high-pressure polyethylene , Spare; its usage is as follows:

[0013] Wash polypropylene waste hollow materials with water, remove debris and dust and cut them into materials of similar size, and take 100 copies for use;

[0014] First, put the above-mentioned spare 100 parts of polypropylene waste hollow material into the mixer, then mix the above-mentioned spare 0.5 parts of chlorinated polyethylene and 8 parts of high-pressure polyethylene into the mixer, start it for 10 minutes under normal temperature conditions, and stop it. , Just unloading and packaging.

Embodiment 2

[0016] This embodiment is basically the same as embodiment 1, except that when the melt flow index M1 is 0.8-1.5, 0.8 parts of chlorinated polyethylene and 9 parts of high-pressure polyethylene are taken.

[0017] In the method of use, put the above-mentioned processed 100 parts of polypropylene waste hollow material into the mixer, then mix the above-mentioned 0.8 parts of chlorinated polyethylene and 9 parts of high-pressure polyethylene into the mixer, and turn it on for 12 minutes at room temperature. Stop, unload and pack.

Embodiment 3

[0019] This embodiment is basically the same as embodiment 1, but the difference is: when the melt flow index M1=1.5-2.0, 1.1 parts of chlorinated polyethylene and 10 parts of high-pressure polyethylene are taken.

[0020] In the method of use, put the above-mentioned processed 100 parts of polypropylene waste hollow material into the mixer, then mix the above 1.1 parts of chlorinated polyethylene and 10 parts of high-pressure polyethylene into the mixer, and start the machine at room temperature for 14 minutes. Stop, unload and pack.

Abstract

The invention discloses a processing modifier used for a polypropylene waste hollow material and an application method thereof. The processing modifier comprises, by weight, 0.5 to 1.5 of chlorinated polyethylene and 8 to 13 of high pressure polyethylene. The application method comprises the following steps: 1, processing the polypropylene waste hollow material; 2, detecting the melt flow index of the polypropylene waste hollow material; 3, preparing materials according to a ratio of the polypropylene waste hollow material to chlorinated polyethylene to high pressure polyethylene of 100: 0.5-1.5: 8-13; and 4, feeding the materials and carrying out processing, that is, successively putting the propotioned materials into a mixer, allowing the mixer to operate for 10 to 15 min at normal temperature, shutting down the mixer and carrying out discharging and packaging. According to the invention, the advantages of a reasonable process, simple processing and convenient usage are obtained, and physicochemical performances of the polypropylene waste hollow material and product quality can be effectively improved. The invention can be widely used for modification and processing of polypropylene waste hollow materials.

Description

Technical field [0001] The invention relates to a processing modifier for plastics and a method of use, in particular to a processing modifier for polypropylene waste hollow materials and a method of use. Background technique [0002] As we all know, the existing polypropylene waste hollow material processing methods are outdated and the technology is backward. The products produced have low physical and chemical properties and poor quality, which cannot meet the needs of consumers, nor can they meet the needs of market development, thus limiting their scope of application . Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology. After the inventor's painstaking research and repeated verification through actual production, it provides a processing modifier for polypropylene waste hollow materials and a method of use. [0004] In order to achieve the above objective, the technical solution o...
