Description
Technical Field
The invention relates to the technical field of new polymer materials, in particular to a flame-retardant high-performance ultrahigh molecular weight polyethylene composite fiber and a preparation method thereof.
Background
Graphene is known as a star material of the 21 st century, and is a nano material in a honeycomb structure only consisting of one layer of carbon atoms. The graphene is of a sheet structure, has stable property, good heat resistance and large specific surface area, and the properties enable the graphene to effectively reduce mass transfer and heat transfer in the material combustion process, thereby improving the flame retardant property of the polymer material. Graphene has a barrier effect to the smallest gas helium, making it unable to penetrate through graphene.
The graphene can improve the thermal stability of related flame retardants, and the addition of the graphene improves the flame retardant performance, so that the addition amount of the graphene is less than that of a single traditional flame retardant, and the problem of the reduction of the mechanical properties of the ultra-high molecular weight polyethylene fibers caused by the addition of a large amount of flame retardants is remarkably improved.
For example, Mg (OH)2The flame retardant effect can be achieved only when the amount of the flame retardant is up to 50% in the polyolefin material, and the mechanical property of the resin matrix material is seriously influenced. Due to the addition of the graphene, the graphene and the graphene have a synergistic effect and are low in addition, so that the ultrahigh molecular weight polyethylene fiber has flame retardant property and good mechanical property. In order to overcome the problem that the mechanical property of a matrix material is obviously reduced due to the addition of a large amount of flame retardant, the patent provides a flame-retardant scheme of the high-performance ultrahigh molecular weight polyethylene composite fiber.

Due to the addition of the graphene, the graphene and the graphene have a synergistic effect, the ultra-high molecular weight polyethylene fiber is low in addition, and the ultra-high molecular weight polyethylene fiber can keep good performance.
The graphene is of a sheet structure, has stable property, strong heat resistance and large specific surface area, can effectively reduce mass transfer and heat transfer in the material combustion process, improves the flame retardant property of a polymer material, and has good barrier effect even on the minimum helium.

step S02: adding ultra-high molecular weight polyethylene powder into the mixture, stirring, and heating for swelling;
step S03: dissolving and homogenizing the prepared raw materials at high temperature by a double-screw extruder, metering, and spinning by a filter and a spinning manifold;
step S04: and then a series of processes of cleaning/extraction, drying and hot drawing are carried out to obtain the flame-retardant high-performance ultrahigh molecular weight polyethylene composite fiber.
In step S01, the dispersing and mixing method includes one or more of mechanical shearing or ultrasonic cavitation, ball milling, sand milling, emulsification or ultrasound.
