Embodiment 1

[0028] This example provides a wear-resistant self-lubricating material for mooring, including the following preparation raw materials in parts by weight:

[0029] Base resin: 10-90 parts,

[0030] Solid lubricant: 5 to 40 parts,

[0031] Inorganic additives: 1-10 parts.

[0032] Among them, 5-40 parts by weight of reinforcing fibers are also included.

[0033] The reinforcing fibers are selected from at least one of glass fibers, metal fibers, graphite fibers and boron fibers.

[0034] The substrate resin is a mixed resin of polyether ether ketone and polytetrafluoroethylene with a mass ratio of 1:3-5.

[0035] The solid lubricant is a mixture of molybdenum disulfide, graphite fluoride and silicon nitride in a mass ratio of 1:2 to 5:1.

[0036] The inorganic additive is a mixture of calcium carbonate, silicon dioxide and copper-aluminum powder in a mass ratio of 3:3:1.

Embodiment 2

[0038] This example provides a method for preparing a wear-resistant self-lubricating material for mooring. In this method, the base resin, solid lubricant and inorganic additives are mixed and melted, and then formed. The melting temperature is 350°C.

Embodiment 3

[0040] In this example, using the formulation of Example 1 and the preparation method of Example 2, four kinds of wear-resistant and self-lubricating materials for mooring, A to D, were prepared. The specific configuration is shown in Table 1.

Abstract

The invention provides a wear-resistant self-lubricating material for mooring, which is prepared from the following raw materials: a base material resin, a solid lubricant, an inorganic additive and reinforcing fibers, and is suitable for preparing a fairlead. The fairlead prepared from the material has a self-lubricating function, the abrasion of a mooring rope can be effectively relieved, the service life of the mooring rope is prolonged, the operation cost of a ship company is reduced, and the material is easily available in raw materials, simple in preparation process and easy to produce and popularize.

Description

technical field [0001] The invention belongs to the technical field of wear-resistant materials, and in particular relates to a wear-resistant self-lubricating material for mooring, a preparation method thereof and a fairlead. Background technique [0002] The fairlead, also known as the "bulwark cable hole", is a closed-hole-shaped fairlead located on the bulwark to limit the position of the cable leading out. It is a circular or oval annular casting. The fairlead is usually made of cast iron or cast steel, installed on the bulwark, guides the cable through the hull, and prevents the cable from damaging the hull. It is widely used in the mooring of ships and ocean engineering, and is an essential device for ships and ocean engineering . [0003] At present, the bollards used on ships are generally steel castings. The bollards and the fairleads on the bollards need to be painted regularly to ensure the normal use of the bollard fairleads. Due to deformation and corrosion,...
