Embodiment 1

[0029]Seefigure 1According to an embodiment of the present invention, a high-temperature ultra-high molecular weight polyethylene material comprising 100 parts of ultra high molecular weight; 0.1 to 5 lubricants; 10 to 20 parts of the filler; 5 to 20 reinforcing fibers; 10 ~ 30 parts, and the filler is kaolin or calcium carbonate.

[0030]A method for preparing high temperature ultra-high molecular weight polyethylene material, characterized in that the specific steps are as follows:

[0031]S1: Ultra-high molecular weight polyethylene and lubricant were obtained in proportion to high speed for 8 to 15 minutes, while stirring, it was heated to 50 to 70 ° C;

[0032]S2: Rehabilitate the filling and reinforcing fibers by a coupling agent;

[0033]S3: Add kaolin or calcium carbonate and filling materials that have been activated by a coupling agent, reinforcing the fibers, stirring at high speed for 3 to 5 minutes to obtain a mixed raw material;

[0034]S4: Due to extruder extruding, composite materi...

Embodiment 2

[0039]Such asfigure 1As shown, the coupling agent is one or more of the silane coupling agent, a titanate coupling agent, an aluminate coupling agent, can improve the interface between inorganic and organic matter, thereby greatly improved The performance of the composite material.

Embodiment 3

[0041]Such asfigure 1As shown, the process of the coupling agent activation treatment is a coupling agent of 0.5-3.5 parts of the total mass of the reinforcing fiber, and the coupling agent is diluted with anhydrous ethanol according to the volume ratio of 8-12: 1. The coupling agent / absorbent ethanol mixed solution is added while stirring, and the mixing solution is added to the solution, and the stirring is continuously stirred, and then the set temperature of 70 to 90 ° C is dried, and after removing Come on.

Abstract

The invention discloses a high-temperature-resistant ultra-high molecular weight polyethylene material and a preparation method thereof. The high-temperature-resistant ultra-high molecular weight polyethylene material comprises 100 parts of ultra-high molecular weight polyethylene, 0.1 to 5 parts of a lubricant; 10 to 20 parts of a filling material; 5 to 20 parts of reinforcing fiber; and 10 to 30 parts of a filler, wherein the filler is kaolin or calcium carbonate. The ultra-high molecular weight polyethylene material has the beneficial effects that when the mass part of the filler is 10-20 parts, the high temperature resistance of the ultra-high molecular weight polyethylene material can be obviously improved on the basis of ensuring the mechanical property, the processing technology property and the use property of ultra-high molecular weight polyethylene, the high temperature resistance is obviously improved, the high temperature resistance of the ultra-high molecular weight polyethylene is improved by about 20%, the filler can be increased to about 30 parts when the ultra-high molecular weight polyethylene is used in workplaces with small stress, and the composite material is safe, environment-friendly, economical and green.

Description

Technical field[0001]The present invention relates to the field of polymer materials, and in particular, to a high temperature ultra high molecular weight polyethylene material and a preparation method thereof.Background technique[0002]Ultra-high molecular weight polyethylene has very excellent characteristics, but its thermal deformation temperature is low, typically 85 ° C, which limits its application in a higher temperature environment. However, when the temperature is increased or when used in a high temperature environment, ultra-high molecular weight polyethylene is generated, and the use is used.[0003]At present, although the modification of ultra-high molecular weight polyethylene at home and abroad is much focused on improving its different performance, such as in U.S. Patent, it can be improved on the basis of not changing other performance. Its molding process performance; Germany O Jacobs, etc., for super high molecular weight polyethylene fibers, significantly improve ...
