Abstract
The invention refers to a kind of electric polyformaldehyde amterial made up of polyformaldehyde, charcoal blacks and the plasticizer according a certain proportion. The invention can make the common non-electric polyformalhyde material augment the electric capability, and it can retain the proper physical capability of the original polyformaldehyde material, and at the same time, it can be used as the electric of the original polyformaldehyde material, and at the same time, it can be used as the electric material and gain more application. The application of the electric material can make the construct of the electrical-apparatus products, such as the portfire of the lighter, simplify, and accordingly enlarge the applied range of the polyformaldehyde material.
Description
Technical field:
The present invention relates to a kind of conductive polyformaldehyde material.
Background technology:
Polyformaldehyde material is used widely as a kind of engineering plastics, but existing polyformaldehyde material is a non-conductive material, thereby makes it can not become a kind of electro-conductive material, is able to further application.
Summary of the invention:
The object of the invention is to provide a kind of conductive polyformaldehyde material, and it can further be used as a kind of electro-conductive material.
Technical solution of the present invention is to form with polyformaldehyde material with based on the weighting agent polymerization granulation of carbon black conductive material, becomes a kind of new polyformaldehyde material with conductivity.
This conductive polyformaldehyde material is combined by a certain percentage by polyoxymethylene, carbon black.Adding matrix polyoxymethylene along with carbon black filled material, polyoxymethylene resistance is sharply reduced, reach desired electric conductivity, but the matrix of polyoxymethylene is subjected to certain decline, for example tensile strength, tensile modulus etc. are subjected to certain influence, at this moment, the softening agent that preferably increases some amount improves the physicals of conductive polyformaldehyde material.
Conductive polyformaldehyde material can be used as the conduction seesaw such as the lighter portfire, automobile fitting conduction accessory and electrical equipment conduction accessory etc.The conductive polyformaldehyde raw material can be as required and purposes, is injected into required product with injection molding machine of plastic.
The present invention makes common non-conductive polyformaldehyde material increase conductivity, has both kept the distinctive physicals of former polyformaldehyde material, can further be used as electro-conductive material simultaneously.The application of this electro-conductive material can make such as electric equipment products simple structureizations such as lighter portfires, thereby enlarges the range of application of polyformaldehyde material
Embodiment:
Present embodiment is a kind of composition of conductive polyformaldehyde material and prepares concise and to the point process.
This conductive polyformaldehyde is mixed and processed by polyoxymethylene and carbon black and dibutylester softening agent.Each component ratio (weight %) is 100 parts of polyoxymethylene base-materials, carbon black 25-30, softening agent 5-6.The present embodiment softening agent uses the dibutylester softening agent.
Get 100 kilograms of polyoxymethylene, 25 kilograms of carbon blacks and 5 kilograms of dibutylesters are put into the mixer heating and are mixed thoroughly, go out the machine extruding pelletization by agent again and become conductive polyformaldehyde material.Forcing machine divides four sections temperature to control, and opening for feed is 60～65 ℃, and second joint is 110～120 ℃, and the 3rd joint is 140～150 ℃, and the 4th joint is 160～170 ℃ and is advisable.After extruding, through after the tank cooling, pull into the conductive polyformaldehyde raw material to tablets press again through tractor.
Claims (5)
1, a kind of conductive polyformaldehyde material is characterized in that this material is combined by a certain percentage by polyoxymethylene, carbon black.
2, conductive polyformaldehyde material according to claim 1 is characterized in that polyoxymethylene and sooty component proportioning (weight %) are polyoxymethylene 100, carbon black 25～30.
