Abstract
The invention relates to an improved plastic material used for manufacturing computer fans, belonging to the technical field of organic materials, comprising a conductive carbon black or graphite, an engineering plastic, a TPEE, a plurality of diffusing oil and a toughener. The improved plastic material is characterized in that the parts by weight of each component are respectively that: the conductive carbon black or graphite of 15 to 22, the engineering plastic of 70 to 80, the TPEE of 5 to 10, the diffusing oil of 0.02 to 0.08 and the toughener of 0.08 to 1.00. The improved plastic material used for manufacturing computer fans has the advantages that: the engineering plastic with additions of the conductive carbon black, the TPEE, the diffusing oil and the toughener has high compressive strength, good toughness and high antistatic property; the computer fans, manufactured by the invented material, without static and dust collection, can effectively improves the task performance and service life of the computer fans.
Description
Technical field
Organic materials technical field of the present invention is specifically related to a kind of improvement that is used to make the plastic material of computer fan.
Background technology
Plastics are widely used in every field as a kind of starting material of processing and manufacturing product.The plastics series products is because of it is corrosion-resistant, in light weight, cost is low and easy for installationly also be popular.But plastic raw materials intensity is low, and is inflammable relatively, adopts the product of its manufacturing also to be easy to produce static, so the performance of plastic material awaits to improve.
The same dust suction problem that causes because of static that exists of the computer fan of existing employing plastic raw materials manufacturing.Generally, the start of computer is all very long runtime, computer fan rotates flabellum for a long time, and friction produces a large amount of positive and negative charges with air, electrostatic adhesion is too much on the computer fan, not only influence the works better of computer fan, and the work-ing life of shortening fan, the dust of electrostatic adhesion is delivered on adjacent other electronic components and also can influences its work-ing life on the while computer fan.
Summary of the invention
Technical problem to be solved by this invention provides a kind of intensity height that is used for, and does not produce the material that electrostatic is used to make computer fan.
For the technical scheme that solves the problems of the technologies described above the present invention's realization is:
A kind of material that is used to make computer fan, include following composition: conductive carbon black or graphite, engineering plastics, TPEE, diffusion oil, toughner, the shared parts by weight of each component are respectively: conductive carbon black or graphite 15～22, engineering plastics 70～80, TPEE 5～10, diffusion oil 0.02～0.08, toughner 0.08～1.00.
The present invention has following unusual effect compared to existing technology:
The engineering plastics of adding graphitized carbon black provided by the present invention, TPEE, diffusion oil and toughner, compressive strength height, good toughness, antistatic property height.Adopt the computer fan of material manufacturing of the present invention, that can effectively improve computer fan does not produce not dust suction of static, effectively raises the task performance and the work-ing life of computer fan.
Embodiment
Embodiment 1
A kind of plastic materials with excellent antistatic energy is provided in the present embodiment, is used to make computer fan.Its preferred component comprises that conductive carbon black, engineering plastics adopt PBTGF15, just adopting the fortifying fibre weight ratio is that 15% PBT moulds fat, TPEE, epoxy soybean oil and chlorinatedpolyethylene, the shared parts by weight of each component are respectively: 18 parts of conductive carbon blacks, 73 parts of PBTGF15,8 parts of TPEE, 0.05 part of epoxy soybean oil, 0.95 part of chlorinatedpolyethylene.
The present invention adds in engineering plastics that electric conductivity that conductive carbon black can effectively improve plastics makes discharge rapidly and the accumulation that prevents electric charge.The engineering plastics of above-mentioned composition can also be conventional polymeric amide, polyoxymethylene, polycarbonate, polyphenylene oxide etc. with glass fibre enhanced plastic material.Engineering plastics density is little, the specific tenacity height, and thermotolerance and dimensional stability height and shock resistance, anti-fatigue performance are also good, can be used to make computer fan.
Adding TPEE in material of the present invention can also make the electric fan of making have high strength, snappiness, oil resistant, high temperature resistant, radiation hardness, the excellent characteristics of dynamic properties.And diffusion oil can also keep certain vividness simultaneously so that material has mutual solubility and non-stick property.
The computer fan that adopts above-mentioned materials to make is compared directly good more lastingly at computer fan surface-coated antistatic coating mode antistatic property.The resistance value that records the computer fan that adopts material of the present invention by experiment illustrates the computer fan electric conductivity height that the relative common material of its electric conductivity is made less than 10 10 powers, can avoid the absorption of static charge.
In addition, experimental results show that by range estimation material of the present invention has antistatic property equally.Place some little paper scrap and dusts at desktop, the fan that fan that common material is made and material of the present invention are made respectively with the hair friction after, be placed on the desktop, can see on the fan of common material manufacturing beginning to adsorb little paper scrap and dust, and the fan surface that material of the present invention is made is very smooth.
Embodiment 2
Present embodiment provided is used to make the material component of computer fan and weight fraction than being 21 parts in graphite, 79 parts of polycarbonate, 5 parts of TPEE, 0.08 part of glycerol, 0.85 part of CALCIUM ACRYLATE base polymer.Adopt the computer fan experiment of present embodiment material manufacturing to have antistatic property equally.
