Description
Technical field
The invention belongs to macromolecular material and forming process field thereof, particularly a kind of continuous glass fibre reinforced nylon 6 prepreg tape and preparation method thereof.
Background technology
Nylon 6 is polyamide resins, one of maximum engineering plastics of application at present, in its structure, contain a large amount of polarity amide groups, can form well-set hydrogen bond, therefore, nylon 6 has higher fusing point, good physical and mechanical property, wear resistance and self lubricity, and these Comprehensive Characteristics are Other Engineering plastics, as not available in PP, PE.Meanwhile, the polarity of amide group, very easily absorbs water nylon 6, causes its rigidity to decline to a great extent, and poor dimensional stability, thereby has limited the application of nylon 6.Therefore, researcher has started the research composite modified to nylon 6 both at home and abroad.And at present, the most generally and the most effectively improve the method for nylon 6 material comprehensive physical mechanical property and use glass fiber reinforced nylon 6.
And in glass fiber-reinforced nylon 6 composite material, glass fibre is divided into staple fibre, macrofiber and three kinds of states of continuous fibre conventionally.During short glass fiber Reinforced Nylon matrix material, need fiber is mixing with resin in forcing machine, due to the shearing action between screw rod and machine barrel, fiber can sustain damage, and length falls sharply, and can not obviously improve the mechanical property of strongthener.Long fiber reinforced Nylon 6 matrix materials, though than short glass fiber reinforced nylon 6 composite materials property, make moderate progress, its intensity still can not meet the requirement that mechanical property is higher.Continuous glass-fiber reinforced nylon 6 matrix material arises at the historic moment, and the principal element that affects continuous glass-fiber reinforced nylon 6 material physical property has two kinds: 1, the wetting property of nylon 6 and glass fibre; 2, the mobility of nylon resin melt.Poor because of the mobility of nylon resin, conventional prepreg tape production method has solution dipping method and molten resin method at present.Though solution dipping method can reach certain dipping effect, the use of solvent, not only to environment, and works the mischief safely to direct labor's health.
Summary of the invention
The object of the invention is to provide a kind of continuous glass fibre reinforced nylon 6 prepreg tape, to solve glass fiber reinforced nylon 6 prepreg tape of the prior art, generally adopt solution dipping method to produce, and the solvent using in production process is not only to environment, and the technical matters that direct labor's health is worked the mischief safely.
