preparation example 1

[0064] The preparation of this application discloses an adsorption-modified nanocarbium carbide, preparing the raw materials required to obtain a recombination modified nano silicon carbide:

[0065] Nano - silicon carbide 200g; ethylene trimethoxysilane 60g.

[0066] The above-mentioned adsorption modified nano silicon carbide was prepared by the following process steps:

[0067] 1200 ml of toluene was added to a 2000 ml of four flasks, 200 g Nano-silicon carbide and 60 g were added to toluene, and nitrogen gas was introduced into the four flasks, and the four flasks were stirred, and the stirring speed was 200R / min. Heat until 90 ° C and constant temperature reaction, the control reaction time was 3 h. After 3 h, the product is hot and vacuum filtration. After two ultrasonic dispersion (with water and acetone), the time of ultrasonic dispersion is controlled for 30 min, then the product is centrifuged (in water and acetone) The control speed is 5000 r / min, the control centri...

Abstract

The invention relates to the technical field of high polymer materials, and particularly discloses creep-resistant fiber and a preparation method thereof. The creep-resistant fiber comprises the following components of ultra-high molecular weight polyethylene, epoxy resin, graphene, nano silicon carbide and mica. The preparation method comprises the following steps of S1, preparing an ultra-high molecular weight polyethylene fiber spinning solution; S2, carrying out extruding and spinning after swelling; S3, after spinning, entering a cold water bath for shock cooling after passing through a spinneret plate; S4, preparing a mixed crosslinking modification solution; S5, carrying out ultrasonic extraction; and S6, carrying out drying and thermal stretching to obtain the creep-resistant ultra-high molecular weight polyethylene fiber. The epoxy resin, the graphene, the nano silicon carbide, the mica, benzoyl peroxide and 3-(acryloyloxy) propyltrimethoxysilane are used for modifying the ultra-high molecular weight polyethylene, and physical filling modification and chemical crosslinking modification methods are matched, so that the heat resistance and creep resistance of the ultra-high molecular weight polyethylene fiber can be further improved.

Description

Technical field [0001] The present application relates to the technical field of polymer materials, and more particularly, it relates to a creep resistant fiber and a preparation method thereof. Background technique [0002] Ultra-high molecular weight polyethylene (UHMWPE) fiber, also known as high-strength high-mode polyethylene fibers, a high-performance fiber developed in 1970, the appearance is white, and the aromatic fiber, carbon fiber is considered to be able to achieve industrial production. High performance fiber. Since the ultra-molecular weight polyethylene fiber has high strength, high modulus, small anti-impact, anti-chemical corrosion performance is good, ultra-high molecular weight polyethylene fibers are widely used in light anti-play helmets, soft anti-flex clothing, etc. field. [0003] In the relevant technique, the preparation process of ultra-high molecular weight polyethylene fibers includes the following process steps: a spinning solution - add an antioxid...
