Technical field
The present invention relates to technical field of composite materials, particularly related to a kind of composite glass fiber and strengthened resin material
And preparation method thereof.
Background technology
(English original name is glass fibre: glass fiber or fiberglass) be the inorganic non-gold of a kind of excellent performance
Belonging to material, of a great variety, advantage is good insulating, thermostability is strong, corrosion resistance good, and mechanical strength is high, but shortcoming is that property is crisp, resistance to
Mill property is poor.It is usually with glass bead or discarded glass for raw material through high temperature melting, wire drawing, doff, the technique manufacture such as weave cotton cloth
Become, a diameter of several microns of its monofilament to twenties meters micron, be equivalent to the 1/20 ~ 1/5 of a hairline, often restraint fibre
Dimension precursor is all made up of hundreds of the most thousands of monofilament.
Graphene, as the allotrope of carbon, is that carbon atom has alveolate texture by what sp2 orbital hybridization was formed
Monolayer two dimensional crystal material, good mechanical performance that Graphene has, chemical stability etc. also will be in fields such as composites
Have broad application prospects.
At present, although have Graphene is coated on fiberglass surfacing with strengthen resin-based materials physical property, but
It is that to improve effect be not highly desirable, need to further enhance.And, have been reported now by adding at fiberglass surfacing
Plus nano silver thus give glass fibre with anti-microbial property, can be applicable to filter paper and resin etc. and make it have antibacterial characteristics;
But nanometer silver is in granular form, often can only be gathered in the specific part of glass fibre, it is impossible to be evenly distributed on surface, thus shadow
The antibacterial effect rung;On the other hand, nanometer silver and glass fibre cannot be combined closely (particularly when nano-Ag particles content increases
Time, it is susceptible to agglomeration), the most easily come off, thus affect service life and antibacterial effect.
