Description
Technical field
The present invention relates to a kind of nylon 66 composite material and preparation method, more particularly to a kind of be applied to office
The nylon 66 composite material and preparation method of automation equipment.
Background technology
With China's rapid development of economy, engineering plastics are increased rapidly in the application of electronic enterprises, its
In it is most widely used be nylon.Glass fiber enhanced nylon 66 (PA66) has excellent mechanical property, but its fire resistance can not
Meet the requirement of electronic enterprises.A large amount of additions of fire retardant, although improve the anti-flammability of material to a certain extent, but
The mechanical property and electrical insulation capability of material all can be greatly affected, and for example phase ratio creepage tracking index (CTI) is under 600
Drop to 250 and lower.
In routine work, office automation devices (computer, printer, facsimile machine) play particularly important effect.Do
The realization of public affairs automation frees clerical workforce from heavy hand labour, enables them that the focus of work is turned to rich
Come in creative management and decision-making, office also will become go slick, high-quality, efficient management, control and decision-making
Center.And the environment of office and safety also can not be ignored, so, a kind of nothing of the high CTI for office automation devices
The research of halogen fire-retardant Nylon 66 composite will receive much concern.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of Halogen, mechanical property are good, flame retardant effect
The low nylon 66 composite material of good, high CTI value, modifying agent addition, it is adaptable to office automation equipment.
The purpose of invention is achieved by the following technical programs：
A kind of nylon 66 composite material for office automation devices, said composition is made up of following raw material, with weight
Amount number meter：Nylon66 fiber be 100 parts, glass fibre be 10-30 parts, acrylonitrile-butadiene-styrene copolymer 10-15 parts,
γ-glycidoxypropyltrime,hoxysilane 0.5-2 part, TAF (the ethylene bis-fatty acids of polar functionalities) 1.5-2 parts, Asia
Phosphotriester 0.5-1 parts, heat stabilizer 0.1-0.5 parts, composite flame-retardant agent are 10-15 parts, are combined CTI modifying agent for 0.5 part.
Wherein, composite flame-retardant agent is the mixture of cyanurate melamine and Firebrake ZB, and the mass ratio of the two is 1:1-2；
Compound CTI modifying agent is the mixture that magnesium carbonate and POE maleic anhydride grafts are constituted with arbitrary proportion.
Preferably, heat stabilizer is dibutyl tin laurate or barium stearate.
Preferably, in the compound CTI modifying agent, magnesium carbonate is 1 with the mass ratio of POE maleic anhydride grafts:1-4.
A kind of preparation method of nylon 66 composite material, comprises the steps：
Step 1, gets the raw materials ready, and nylon particles are crushed；
Step 2, draw ratio is added to for 40-50 by the raw material in addition to glass fibre:Melt in 1 double screw extruder
Mixing dispersion；
Step 3, glass fibre is added from side spout；
Step 4, the temperature control in each area of double screw extruder is extruded from extruder, granulated at 220-250 DEG C.
Preferably, step 1 nylon particles are crushed and obtain nylon powder of the particle diameter less than 0.5 μm.
Preferably, the rotating speed of each area's main frame of double screw extruder is 300～450RPM, and feed rate is 30～60RPM.
Relative to prior art, beneficial effects of the present invention：
1st, the modified PA66 of fiberglass reinforced, glass plays the humidification of skeleton structure type in PA66.When by negative
During lotus, due to glass presence, make load along glass transfers, stress is spread rapidly and is prevented the growth of crackle, because
The increase of this glass fiber content, the mechanical property for making PA66 is improved.But after due to adding glass fibre, glass fibre serves " candle
Core " is acted on so as to which grade of burning declines.The present invention is dropped using addition toughener (acrylonitrile-butadiene-styrene copolymer)
Low glass addition, using composite flame-retardant agent, reduces the addition of fire retardant, and not only fire resistance is good for modified PA66, and
And still keep good mechanical property.
2nd, because the membership that adds of fire retardant declines CTI values, in order to improve this case, this composite is additionally added CTI
Modifying agent, CTI modifying agent additions are low, do not affect material mechanical performance and fire resistance, and possess higher CTI values (
More than 500).
