Embodiment 1

[0025] Special materials for modified recycled polyethylene pipes and pipe fittings, mainly composed of the following substances in weight percentage:

[0026] 7% polyethylene, 33% recycled polyethylene, 10% toughening agent, 20% talc, 2500 mesh 23% calcium carbonate, 1% impact modifier, 0.1% diiso peroxide Propylene, 0.4% antioxidant 1010, 0.5% silane coupling agent, 0.5% polyethylene wax, 2.5% calcium stearate, 2% pigment.

[0027] The specific preparation method is as follows:

[0028] Firstly, the waste polyethylene is crushed, washed, dried, and homogenized to obtain recycled polyethylene. In order to avoid other impurities mixed in the waste polyethylene from affecting it, a blower is also used to blow out other light items mixed in the waste polyethylene during the drying process, and the light items are plastic labels etc.

[0029] The above-mentioned substances are passed into the batching machine at the above-mentioned ratio through the batching machine, and they ...

Embodiment 2

[0031] The difference between this embodiment and Example 1 is that the percentage content of each component is different, and the percentage content of each component is as follows in the present embodiment:

[0032] 25% polyethylene, 15% recycled polyethylene, 20% toughener, 5% talc, 2500 mesh 15% calcium carbonate, 3% impact modifier, 2% diisoperoxide Propylene, 2% antioxidant 1010, 3% silane coupling agent, 3% polyethylene wax, 3% calcium stearate, 4% pigment.

Embodiment 3

[0034] The difference between this embodiment and Example 1 is that the percentage content of each component is different, and the percentage content of each component in the present embodiment is as follows:

[0035] 7% polyethylene, 70% recycled polyethylene, 5% toughening agent, 5% talc, 2500 mesh 5% calcium carbonate, 5% impact modifier, 0.4% diiso peroxide Propylene, 0.6% antioxidant 1010, 0.5% silane coupling agent, 0.6% polyethylene wax, 0.5% calcium stearate, 0.4% pigment.

Abstract

The invention discloses a special modified recycled polyethylene material for cables and a preparation method of the special modified recycled polyethylene material, so that the problem of high production cost due to the fact that existing special modified polyethylene materials for cables are prepared from new polyethylene and the problem of raw material and cost pressure of existing polyethylene are solved. The special modified recycled polyethylene material for the cables mainly comprises, by weight, 7%-69% of polyethylene, 10%-70% of recycled polyethylene, 5%-20% of toughening agents, 5%-40% of talcum powder, 5%-40% of calcium carbonate, 1%-5% of impact modifiers, 0.1%-2% of dicumyl peroxide, 0.4%-2% of antioxidants 1010, 0.5%-3% of silane coupling agents, 0.5%-3% of polyethylene wax, 0.5%-3% of calcium stearate and 0.4%-4% of pigment. Waste polyethylene can be recycled and reused effectively, and the special modified recycled polyethylene material for the cables and the preparation method have the advantages of resource saving, environmental protection, cost reduction and the like.

Description

technical field [0001] The invention relates to a modified polyethylene, in particular to a modified recycled polyethylene special material for cables and a preparation method thereof. Background technique [0002] The English name of polyethylene is polyethylene, and it is referred to as PE. The polyethylene is a thermoplastic resin obtained by polymerizing ethylene. [0003] The main production method of olefin products in my country is prepared from naphtha, and my country is a country with "low oil, short of gas and rich in coal". This situation will inevitably lead to the shortage of olefin products in my country, which will lead to the existence of raw materials and costs for polyethylene. pressure. Moreover, the existing modified polyethylene special materials for preparing cables are all prepared by mixing new polyethylene with other components, resulting in high use costs. Contents of the invention [0004] The purpose of the present invention is to solve the pr...
