Abstract

The invention discloses a preparation method of a novel bearing composite material. The preparation method comprises the following steps: adding nano-rare earth particles into graphene, uniformly mixing, raising the temperature to 80-90 DEG C within 1 minute, maintaining the temperature for 5-10 minutes, and cooling to 40-50 DEG C within 10 seconds, adding unsaturated polyester resin, an initiator, polyurethane, a low shrinkage additive, an internal releasing agent, a cross-linking agent, a thickening agent, a coupling agent, methyl stearate, ammonium chloride and glass fibers, and uniformly mixing to obtain a mixture A; laying one part of the mixture A in a mold-pressing mold, placing carbon fibers and aramid fibers on the mold-pressing mold laid with one part of the mixture A, and layingthe residual mixture A on the mold; raising the temperature of the mold-pressing mold to 60-95 DEG C, maintaining the temperature for at least 6 minutes, and applying a pressure of 900-1500 tonnagesfor at least 8 minutes to obtain the composite material. The preparation method disclosed by the invention is an integrated molding technology, and the material is light in weight and excellent in mechanical property.

Description

technical field

[0001] The invention belongs to the technical field of load-bearing materials, and in particular relates to a preparation method of a novel load-bearing composite material. Background technique

[0002] Existing handling equipment (such as fork plates, forklift frames, truck frames, and brackets) is mainly composed of steel components, and the manufacturing process is cumbersome and complicated. It mainly uses the rigidity of raw materials and the reasonable structural force distribution of components to achieve Auxiliary handling purposes. However, the equipment composed of steel components is very cumbersome, which is contrary to the purpose of assisting in the transportation of heavy objects, and its mechanical properties are increasingly difficult to meet the requirements of higher strength. At the same time, steel materials are not suitable for handling static-sensitive equipment. In addition, insulators tend to generate static charges due to friction ...
