Infectious disease, mapping, news report, electric inspection process, the disaster relief, movies-making, manufacture romance etc., have greatly expanded unmanned plane sheet
The purposes of body, developed country also in actively extension industrial application and develop unmanned air vehicle technique.
Important component of the unmanned aerial vehicle body as unmanned plane, carry various kinds of sensors, navigation system, engine with
And other function devices, this proposes strict requirements to unmanned aerial vehicle body material, and traditional unmanned aerial vehicle body making material is
Aluminium alloy, aluminum alloy materials are not able to satisfy unmanned aerial vehicle body lightweight development from great, fatigue resistance is poor, poor corrosion resistance
Demand.For this purpose, being developed macromolecule engineering plastic material.Existing unmanned plane making material be mostly polystyrene foam or
Cork wood covering adds glass reinforced plastic, needs during the curved surface forming of fuselage to polystyrene foam according to polystyrene foam
Cut, and it is complicated curved surface is to the more demanding of cutting technique and time-consuming, increase being prepared into for unmanned aerial vehicle body
This, meanwhile, foam is easy to be corroded by glue, and water suction dampness is easy after molding leads to shape deformation, reduces unmanned plane structure
Intensity；Glass reinforced plastic is added to make according to cork wood covering, the material is more thick and heavy, causes body weight after molding excessive, serious to drop
The low load-carrying ability of unmanned plane, and components are more fragile under low temperature environment, it is easy to damage during benefiting from.
It would therefore be highly desirable to research and develop a kind of new unmanned aerial vehicle body material, so as to solve the deficiencies in the prior art.
Carbon fiber (carbon fiber, abbreviation CF) is a kind of high intensity 95% or more of phosphorus content, high modulus fibre
New fiber materials.It is to be piled up by organic fibers such as flake graphites along fiber axial direction, through carbonization and stone
Microcrystalline graphite material obtained from blackization processing.Carbon fiber " soft outside but hard inside ", quality is lighter than metallic aluminium, but intensity is higher than steel
Iron, and there is corrosion-resistant, high-modulus characteristic, it is all important materials in defence and military and civilian aspect.It not only has carbon
The intrinsic intrinsic property of material, and have both the soft machinability of textile fabric, it is reinforcing fiber of new generation.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of unmanned plane fiber alloy PVC modified materials, should
PVC modified composite material light weight, high mechanical strength, tensile strength and tear resistance are excellent, good corrosion resistance, it is not easy to old
Change, fire protecting performance it is excellent, the particular/special requirement of can meet unmanned plane long storage life in the presence of a harsh environment reduces maintenance cost and week
Phase, integral forming technique is easy, and exterior design strong applicability has preferable application prospect.

The plastic components based on PMMV on rubbery kernel have good compatibility with polyvinyl chloride resin, can promote modifying agent
PVC's is evenly dispersed, and improves the caking property of rubber particle and polyvinyl chloride resin.
The carbon fiber has excellent electric conductivity, after PVC is added, can be effectively reduced the sheet resistance of PVC, to mention
The antistatic property of high material, for being electromagnetically shielded environment.
The lubricant is selected from saturated hydrocarbons, metal soap, aliphatic amide, fatty acid or fatty alcohols.In PVC tree
Become the viscous liquid for becoming flowing by melting in rouge process from solid-state or particle, during being somebody's turn to do, lubricant fusing point is low, first
Melt be liquid, into also do not melt resin particle in or resin-coated particle exterior surface, reduce resin inside or resin with
Frictional force and adhesiveness between equipment, are conducive to demould, and regulate and control resin plasticization speed, delay plasticizing.
Nanometer calcium carbonate is selected in the toughness agent, and nanometer calcium carbonate is uniformly distributed in the PVC, with PVC interface cohesion
Power is good, improves the notch impact strength of material, keeps the rigidity of material.
The preparation method of above-mentioned unmanned plane fiber alloy PVC modified material, includes the following steps:
By PVC, after nanometer calcium carbonate and the mixing of ACR resin, in a high speed mixer in 110 DEG C of kneading 20-30min, obtain
