Problems solved by technology

[0003] However, at present, most of the technologies and processes for producing agricultural PE water delivery hoses at home and abroad follow the common extrusion process and are produced with a single type of polyethylene raw material, which has the disadvantages of poor weather resistance, low strength, thick wall thickness and rice heavy questions

Embodiment 1

[0042] Thin-wall high-pressure resistant PE hose, prepared from the following components by weight percentage: 37% high-density polyethylene, 20% low-density polyethylene, 29% linear low-density polyethylene, 8% modified alumina , 3% fluoropolymer additive PPA functional masterbatch and 3% polyethylene black masterbatch.

[0043] Wherein, the particle size of the modified alumina is 800 mesh.

[0044] The reason for choosing modified alumina is that alumina is obtained by chemically treating bauxite raw materials to remove oxides such as silicon, iron, and titanium. It is a high-purity alumina raw material with an average Al?O? content. It is more than 99%, but there is a huge difference in the physical and chemical properties of unmodified alumina and polymer materials, which easily leads to poor wettability between different components during the compounding process, and the compounding quality is not high. Modified alumina is obtained by surface chemical modification, whic...

Embodiment 2

[0053] Thin-walled high-pressure resistant PE hose, prepared from the following components by weight percentage: 41% high-density polyethylene, 16% low-density polyethylene, 25% linear low-density polyethylene, 12% particle size of 1000 mesh Modified alumina, 2% fluoropolymer additive PPA functional masterbatch and 4% polyethylene black masterbatch.

[0054] The preparation method for realizing the thin-walled high-pressure resistant PE hose is the same as in Example 1.

Embodiment 3

[0056] Thin-walled high-pressure resistant PE hose, prepared from the following components by weight: 43% high-density polyethylene, 12% low-density polyethylene, 21% linear low-density polyethylene, 18% particle size of 1300 mesh Modified alumina, 1% fluoropolymer additive PPA functional masterbatch and 5% polyethylene black masterbatch.

[0057] The preparation method for realizing the thin-walled high-pressure resistant PE hose is the same as that in Example 1.

Abstract

The invention provides a thin-wall and high-pressure-resisting PE (Polyethylene) hose and a preparation method thereof. The thin-wall and high-pressure-resisting PE hose is prepared from the following components in percentage by weight: 35%-45% of high density polyethylene, 10%-22% of low density polyethylene, 20%-30% of linear low density polyethylene, 6%-20% of modified aluminum oxide and 0.5%-4% of a fluorine-containing polymer auxiliary agent PPA (phenyl-propanolamine) functional master batch. According to the thin-wall and high-pressure-resisting PE hose, modified aluminum oxide is added into a formula to improve the heat conductivity of the PE hose so that the weather resistance of the PE hose is improved; the modified aluminum oxide is added so that the tensile strength of the material is improved and the aim of reducing the wall thickness of the PE hose is realized under the precondition of guaranteeing that various performance indexes of the PE hose reach the standard.

Description

technical field [0001] The invention belongs to the technical field of polyethylene (PE) hose manufacture, and in particular relates to a thin-walled high-pressure resistant PE hose and a preparation method thereof. Background technique [0002] There are more than dozens of water-saving irrigation technologies being promoted and used in my country, mainly pipe irrigation, sprinkler irrigation, drip irrigation, micro-sprinkler irrigation, seepage irrigation and underground irrigation. In the above efficient irrigation methods such as drip irrigation, pipe irrigation and other water-saving irrigation, a large number of agricultural PE water delivery hoses are required. [0003] However, at present, most of the technologies and processes for producing agricultural PE water delivery hoses at home and abroad follow the common extrusion process and are produced with a single type of polyethylene raw material, which has the disadvantages of poor weather resistance, low strength, t...
