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 low-pressure polyethylene waste hollow material=0.5~0.8, then take 1.2 parts of chlorinated polyethylene, tert-butyl peroxide 0.3 part of diisopropylbenzene is standby; Its using method is as follows:

[0013] Wash the low-pressure polyethylene waste hollow material with water, remove sundries and dust, cut it into waste pipe materials of similar size, and take 100 parts for later use;

[0014] First put 100 parts of the above-mentioned processed low-pressure polyethylene waste hollow materials into the mixer, then mix the above-mentioned 1.2 parts of chlorinated polyethylene and 0.3 parts of tert-butylperoxydicumyl into the mixer, and put them into the mixer under normal temperature conditions. Turn on the machine for 12 minutes, stop the machine, and unload and pack.

Embodiment 2

[0016] This embodiment is basically the same as Example 1, except that: when the melt flow index M1=0.8~1.5, then take 1.3 parts of chlorinated polyethylene and 0.36 parts of tert-butylperoxydicumene .

[0017] In the method of use, put 100 parts of the above-mentioned processed low-pressure polyethylene waste hollow materials into the mixer, then mix the above-mentioned 1.3 parts of chlorinated polyethylene and 0.36 parts of tert-butylperoxydicumyl into the mixer, and then put them into the mixer. Start the machine for 13 minutes at room temperature, stop it, and unload and pack it.

Embodiment 3

[0019] This embodiment is basically the same as Example 1, except that: when the melt flow index M1=1.5~2.0, then take 1.4 parts of chlorinated polyethylene and 0.4 part of tert-butylperoxydiisopropylbenzene .

[0020] In the method of use, put 100 parts of the above-mentioned treated low-pressure polyethylene waste hollow materials into the mixer, then mix the above-mentioned 1.4 parts of chlorinated polyethylene and 0.4 parts of tert-butylperoxydicumene into the mixer, and then put them into the mixer. Start the machine for 14 minutes at room temperature, stop it, and unload and pack it.

Abstract

The invention discloses a processing modifier for modifying a low-pressure polyethylene waste hollow material into a material special for a pipe, and a using method for the processing modifier. The processing modifier comprises the following components in part by weight: 1.2 to 1.5 parts of chlorinated polyethylene and 0.3 to 0.5 part of tert-butylperoxy diisopropyl benzene. The using method comprises the following steps of: 1, processing a low-pressure polyethylene waste hollow material; 2, detecting a melt flow index of the low-pressure polyethylene waste hollow material; 3, batching in a ratio of the low-pressure polyethylene waste hollow material to chlorinated polyethylene to tert-butylperoxy diisopropyl benzene of 100:(1.2-1.5):(0.3-0.5); and 4, charging for processing, namely putting the prepared components into a mixer, starting under the normal temperature and mixing for 12 to 15 minutes, stopping, and unloading and packaging. The processing modifier is reasonable in process, easy to process and convenient to use, and can effectively improve the physicochemical performance of the low-pressure polyethylene waste hollow material and the quality of a product. The processing modifier can be widely used for modifying the low-pressure polyethylene waste hollow material.

Description

technical field [0001] The invention relates to a processing modifier for plastics and a usage method thereof, in particular to a processing modifier for modifying low-pressure polyethylene waste hollow material into a special pipe material and a usage method thereof. Background technique [0002] As we all know, the existing low-pressure polyethylene waste hollow material processing methods are outdated and the technology is backward, and the products produced have low physical and chemical properties and poor quality, which cannot meet the needs of consumers or meet the needs of market development, thus limiting its application. scope. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiency of the above-mentioned background technology. After the inventor's painstaking research and repeated verification through the actual production, a processing modifier and a processing modifier for modifying low-pressure polyethylene waste ...
