Embodiment Construction

[0007] Below in conjunction with specific embodiment, the present invention is described in further detail, but the present invention is not limited to following examples of implementation:

[0008] In this embodiment, co-rotating twin-screw extruders, mills, and injection molding machines are used; ultra-high molecular weight polyethylene is produced in Beijing Auxiliary No. For domestic production.

[0009] The preparation process of a wear-resistant ultra-high molecular weight polyethylene composite material for marine use according to the present invention is as follows:

[0010] Firstly, the UHMWPE and the anti-salt corrosion material were mixed in an open mill at a temperature of 210°C for 30 minutes according to the ratio in the example in Table 1, and the mixed composition was pulverized into a diameter less than 3mm by a pulverizer.

[0011] The formula corresponding to table 1 embodiment

[0012]

[0013] According to the ratio of the example in Table 2, the c...

Abstract

The invention discloses a marine wear-resistant ultrahigh-molecular-weight polyethylene composite material. The composite material is prepared by mixing ultrahigh-molecular-weight polyethylene having the viscosity average molecular weight of 3000000-3500000 and a salt corrosion resistant material by an open mill to form a mixture, then adding a proper amount of a processing flow modifier, a compatibilizer and an antioxidant, and preparing by a twin-screw extruder. The composite material comprises the components in parts by weight: 80-90 parts of the ultrahigh-molecular-weight polyethylene, 5-10 parts of the salt corrosion resistant material, 5-10 parts of the processing flow modifier, 0.2-0.4 part of the compatibilizer, and 0.2-0.4 part of the antioxidant. The preparation comprises the steps: weighing the raw materials according to the proportion, firstly mixing in the open mill to form the mixture, again weighing the raw materials according to the proportion, extruding by the twin-screw extruder, and thus obtaining the product. The composite material can be widely used in the field of ship navigation. The preparation process is easy to control, high in production efficiency, and stable in quality.

Description

technical field [0001] The invention discloses a wear-resistant ultra-high molecular weight polyethylene composite material for marine use. It specifically relates to a composite material with excellent mechanical properties, wear resistance, seawater corrosion resistance and aging resistance, which can be widely used in the field of ocean ships. Background technique [0002] Ultra-high molecular weight polyethylene material has excellent properties and is called "amazing plastic". There is a tendency to replace some steel materials in some fields. With the in-depth development of the marine ship industry, the application of ultra-high molecular weight polyethylene materials in the ship field has emerged, and the requirements are getting higher and higher, not only to reduce the weight of the ship itself, but also to seawater corrosion and anti-oxidation aging requirements. high. Therefore, developing a suitable ultra-high molecular weight polyethylene composite material ...
