Description

A kind of novel wear resistant electric armour clamp fire-retardant nylon composite and preparation method thereof
Technical field
The present invention relates to technical field of composite materials, more particularly to a kind of novel wear resistant electric armour clamp is compound with fire-retardant nylon Material and preparation method thereof.
Background technology
Electric armour clamp be connection and combinational electric system in all kinds of devices, play transmission mechanical load, electrical load and The metal-ware of certain protective action, used as part indispensable on transmission line of electricity, its electric energy loss is always power department The problem of concern.In addition to improving from electric armour clamp casting technique, the selection to its material is particularly important, and material is prepared at present Mainly based on nonmagnetic aluminium alloy, although compared with the ferrimagnet for using in the past, electrical network energy-saving and emission-reduction are played necessarily Effect, but used as metallic conductor, eddy-current loss is still present, and energy loss is still unavoidable from, and Al-alloy products must Must obtain through the high energy consumptions such as ore dressing, exploitation, electrolysis, melting, high pollution operation, belong to national developmental limitation industry, it is impossible to full The economic needs of sufficient transmission line of electricity.Replace metal material with insulant, so that it may reduce eddy-current loss, reach more preferable energy-conservation effect Really.With the fast development of brand-new material science, the composite with insulating properties is applied to more and more power industry In, as the making material of electric armour clamp, it is up to decrease or even eliminate the purpose of eddy-current loss.
It is known that fibre reinforced composites have the performance such as lightweight, high-strength, anti-corrosion, insulation, environmental protection, in power industry Be widely used in transmission and distribution networkses, thus in order to solve the problems, such as electric line in steel and aluminum alloy hardware high energy consumption, Reduce line loss, document《The development and application of modified composite material conductor spacer and suspension clamp》Tens of kinds of engineering plastics are entered Go and selected and study, it is determined that using PA66 nylon as the base material of composite.In the substrate add glass fibre, toughener, Resistance to ozone and corrosion-resistant etc. material modified, and by repetition test test and formulation optimization, successfully develop a kind of modified compound Material, and the design of conductor spacer and suspension clamp, trial-production and experimental study based on modified composite material have been carried out, as a result show it Performance meets national standard and power industry standard requirement, and the suspension clamp based on composite has been applied to 35 kV and 220 In kV overhead transmission lines, operation conditions is good.
Belong to combustible material yet with nylon material, electric armour clamp is used for for a long time open air, especially during the broiling summer Hold fire hazardous with dry winter, and the improvement of the performance such as fire-retardant to material in document, cold-resistant, ageing-resistant does not add elaboration, Thus the electric armour clamp with fire resistance for developing a kind of multifunction efficient energy-saving have with modified composite nylon material it is good Good application prospect.
The content of the invention
The object of the invention is exactly to make up the defect of prior art, there is provided a kind of novel wear resistant electric armour clamp uses fire-retardant Buddhist nun Imperial composite and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of novel wear resistant electric armour clamp fire-retardant nylon composite, is prepared by the raw materials in：Nylon66 fiber 79- 83rd, terpene resin 13-15, carbon fiber 25-27, melamine cyanurate 8.5-8.7, silicon nitride 21-24, precipitated calcium carbonate 7- 9th, UV absorbers 0.1-0.3, phenyl triethoxysilane 8-9, Propylene Glycol 3-4, Fanglun slurry cake 9-10, potato full-powder 4- 5。
A kind of described novel wear resistant electric armour clamp manufacture method of fire-retardant nylon composite, comprises the following steps：
（1）Potato full-powder is added stirring and evenly mixing heated and boiled in the water of 10-12 times of quality, keeping temperature add lightweight carbonic acid Calcium, Propylene Glycol continue to stir 10-20 minutes, are cooled to 45-55 DEG C, add melamine cyanurate ultrasonic disperse 20-30 point Clock, is spray-dried to obtain modified melamine cyanurate；
（2）By silicon nitride in 820-920 DEG C of calcination processing 30-40 minute, 75-80 DEG C of addition phenyl triethoxysilane is cooled to Ultrasonic disperse 10-15 minutes, room temperature dries the silicon nitride that must be modified；
（3）Carbon fiber is placed in the salpeter solution that mass concentration is 25%-40%, is soaked 10-20 minutes under room temperature condition, then With in the sodium hydroxide solution of mass concentration 5%-20% and residual acid solution, final rinse water to neutrality is dried must be roughened place Reason carbon fiber；
（4）By nylon66 fiber, terpene resin, Fanglun slurry cake, step（1）、（2）Material and other residual componentss mix in mixer Uniformly, Jing upstreams spout, sends into double screw extruder, while by step（3）Middle roughening treatment carbon fiber Jing fed downstream mouths, Send into double screw extruder melting extrusion, pelletize, discharging.
It is an advantage of the invention that：The present invention adds precipitated calcium carbonate, Propylene Glycol with melamine cyanurate as fire retardant After being modified its crystal can be generally uniformly dispersed in nylon matrix, in burning by itself endothermic decomposition, produce not Fuel gas, realizes that gas phase is intercepted, and so as to play fire retardation, and leaves nanoporous on composite self-extinguishment face；This Invention using silicon nitride carry out it is silane-modified after be added in raw material as heat filling, and the good dispersion of wellability of nylon matrix is equal It is even, improve the thermal diffusivity and heat resistance of material；Again other effective ingredient of compatibility are mutual as reinforcing material for addition carbon fiber Compound obtained electric armour clamp tensile strength, hardness and wearability are preferable.
