Description
Technical field
The present invention relates to a kind of major diameter copolyamide monofilament and production method thereof of nano modification.
Background technology
Polyamide (PA is commonly called as nylon), occupies first of five large general engineering plastic.Have that intensity is large, fusing point is high, the advantage such as, good heat resistance stable to chemical reagent (except strong acid), be the maximum engineering plastics of output.But due to can hydrogen bond be formed between the amide groups of nylon and hydrone, make nylon have larger water imbibition, cause the shortcomings such as impact strength is low, opaque, poorly soluble under product size poor stability, dry state or low temperature, limit its range of application.
Copolyamide engineering plastics not only have the general character of homopolymerization Polyamide Engineering Plastic, as good mechanical property, toughness, self lubricity, chemical proofing, but also can by selecting to improve the heat resistance of material and impact resistance etc. with different monomers copolymerization.Copolyamide is also easily by strengthening in addition.Filling or other polyblends are made the methods such as alloy and are carried out modification, form new kind.Large Polyamide Engineering Plastic production company of external a few family develops high-performance copolyamide engineering plastics all in succession, the beautiful and space Bu Xingchandeng company in the east as the BASF of the Du Pont of the U.S., Germany, Japan.
Summary of the invention
The object of the present invention is to provide a kind of technique simple, diameter is large, and anti-wear performance is good, and monofilament roundness is high, the major diameter copolyamide monofilament of the nano modification of long service life and production method thereof.
Technical solution of the present invention is:
