Abstract

The invention discloses an ultra-high molecular weight polyethylene (UHMPE) and nano-inorganic substance composite material and a manufacturing method of high-performance fiber thereof, belonging to the field of a composite material.The manufacturing method of the composite material comprises the following steps: preparing UHMPE and a nano-inorganic substance, such as attapulgite, a carbon nanotube, sepiolite, wollastonite, montmorillonite and the like into gel solution; in the case of light transmittance close to zero under certain concentration, heating the gel solution for dissolving; and vacuumizing, defoaming, spinning with different spinneret boards containing various spinneret angles as well as feed length and discharge length, carrying out air-quenching, carrying out aqueous-phase curing, performing multi-segment temperature change extension and the like to finally obtain the composite material for the ultra-high strength fiber the light transmittance of which is close to zero. The obtained composite material can increase the strength and modulus of UHMPE fiber and solve the defects of the UHMPE fiber, such as high crimp, high creep, light transmittance and the like.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a composite material of ultra-high molecular weight polyethylene and nano-inorganic substances and a method for manufacturing high-performance fibers thereof. Background technique [0002] In recent years, following high-performance fibers such as carbon fibers and aromatic polyamides, an ultra-high molecular weight polyethylene (UHMWPE) fiber has been developed. The ultra-high molecular weight polyethylene fiber has high strength, high modulus, Wear-resistant, corrosion-resistant and light-resistant properties, can be widely used in various fields to achieve various purposes, for example: in marine engineering, it can be applied to fixed anchor ropes such as supertankers, offshore operating platforms and lighthouses, which can solve the traditional use of steel Corrosion caused by immersion in seawater, and the use of nylon or polyester cables will cause corrosion, hydrolysis ...
