Description
Technical field
The present invention relates to a kind of nylon composite draw-bar box castor, especially a kind of carbon fiber reinforced nylon composite draw-bar box foot
Wheel.
Background technology
Draw-bar box castor system material (containing support and castor) the most all produces with enhancing nylon.Nylon mainly passes through
Fibre modification, can significantly improve resistance to acids and bases and the physical and mechanical properties of nylon so that it is the scope of application is wider, and therefore fiber changes
Property nylon has great importance.Strengthen nylon and include that glass fiber reinforcement class/fibre reinforced class/basalt fibre strengthens class
And aramid fiber strengthens class.Wherein based on glass fibre and fibre reinforced class, glass fibre reinforced nylon is with polymer
For matrix, make composite with glass fibre as reinforcing material, combine the performance of polymer and glass fibre, have strong
Spend the advantages such as high, corrosion-resistant, heat insulation, molding shrinkage is little.Along with developing by leaps and bounds of application market, glass fibre reinforced nylon is carried
Go out higher requirement.Domestic glass fiber reinforced nylon material substantial amounts of theoretical research and product development are carried out, glass from matrix
Fine content, glass size, the dispersibility of glass, glass and the bonding degree of nylon base material, various auxiliary agent proper use of
The different aspect such as the adjustment of process conditions is studied, and achieves progress, but is improving the intensity of nylon, dimensional stability
Obtain outside breakthrough with reducing water absorption rate, also bring a series of problem, such as: when glass fiber content exceedes a certain amount of, compound system
Melt viscosity increase, not only cause machine-shaping difficulty, and goods easily occur that glass emergence on the surface, rough surface etc. are bad existing
As, when applying in draw-bar box castor system accessories, except above unfavorable condition, also occur that accessory weight increases, therefore develop
High-performance, high-quality enhancing nylon imperative.
Carbon fiber modifying nylon material development in recent years is very fast, because nylon and carbon fiber are all respective field excellent performances
Material, its composite comprehensively embodies both superioritys, and carbon fiber has that light weight, hot strength be high, wear-resistant, corrosion resistant
The features such as erosion, creep resistant, conduction, heat conduction, compared with glass fibre, modulus is high 35 times, thus be a kind of obtain high rigidity and
The excellent reinforcing material of high-strength nylon material, the most external nylon 6 or 66 of employing mostly is as matrix material, with chopped or length
Carbon fiber have studied its bending of carbon fiber of interpolation 20% as reinforcing material, such as Wilson-Fibertil international corporation of the U.S.
Intensity is identical with the fiber glass reinforcement adding 40%.Domestic also having carried out relevant research and test, lot of experiments is tied
Fruit show: carbon fiber reinforced nylon can make the hot strength of nylon composite materials, bending strength, bending modulus, case hardness,
Wearability increases, heat-resist, the sassafras coefficient that rubs is little, lightweight number of advantages of Denging, but carbon fibre reinforcement also has its shortcoming,
As: cost is high, processability is bad, surface smoothness is the most high.Therefore the carbon fibre of high-performance, the processing of moderate cost easy-formation is developed
Dimension strengthens the developing direction that nylon composite materials is modifying plastics industry.
