Abstract

The invention relates to a method for modifying a nanometer sol ultrahigh molecular weight polyethylene fiber by plasma treatment. The method comprises that: (1) inorganic nanometer particle is prepared into a sol solution by an ultrasonic shock technique; or (2) a precursor solution of the organic-inorganic nanometer particle is subjected to hybridization reaction with the inorganic nanometer particle to prepare the sol solution; (3) the sol solution is coated on the surface of the ultrahigh molecular weight polyethylene fiber; and (4) the ultrahigh molecular weight polyethylene fiber is dried at a temperature of 10 and 150 DEG C, and the solvent is collected; the ultrahigh molecular weight polyethylene fiber is introduced in a plasma atmosphere region by a plasma generator for plasma surface modification; and the treated ultrahigh molecular weight polyethylene fiber is on-line rolled by an automatic rolling machine. The compound property between the treated ultrahigh molecular weight polyethylene fiber and the organic matrix materials is greatly improved; moreover, the method also has the advantages of simple process, good treatment effect, low cost, environmental protection and low energy consumption.

Description

technical field [0001] The invention belongs to the field of preparation of ultra-high molecular weight polyethylene fiber surface modification, in particular to a method for plasma treatment of nano-sol ultra-high molecular weight polyethylene fiber modification. Background technique [0002] Ultra-high molecular weight polyethylene (UHMWPE) fiber is a high-performance fiber that appeared after carbon fiber and aramid fiber. It is made of ultra-high molecular weight polyethylene, through high-pressure solid-state extrusion method, plasticized melt spinning method, surface crystal growth method, super-stretching or partial super-stretching method, gel spinning-hot stretching method, etc. It is a high-performance fiber with high strength and high modulus. Its relative molecular mass is 1 million to 6 million, its molecular shape is a linear extended chain structure, its orientation degree is close to 100%, its strength is equivalent to about 15 times that of high-quality ste...
