Abstract

The invention discloses conductive plastic. The conductive plastic is composed of a plastic body, a plasticizer and a conductive material, wherein the conductive material is conductive fiber, and the plastic body, the plasticizer and the conductive material respectively accounts for 35-50 percent, 40-45 percent and 10-20 percent of the conductive plastic in weight.

Description

A kind of conductive plastics

Technical field

The present invention relates to a kind of conductive plastics, particularly a kind of industrial conductive plastics.

Background technology

Plastics can be described as polymer or giant molecule (macromolecules) again for synthetic macromolecular compound { polymkeric substance (polymer) }, also are plastics (plastics) or the resins (resin) that generally is commonly called as, and can freely change the body pattern.Be the material that utilizes raw material monomer to be polymerized with synthetic or condensation reaction, formed by additives such as synthetic resins and filler, softening agent, stablizer, lubricant, colorants.According to American Society for testing and materials under definition, plastics be a kind of be the material of main component with high-molecular-weight organic material matter, it presents solid shape when machining, make and the course of processing in, can borrow flow (flow) come moulding.Therefore, through illustrating that thus we can obtain following several understandings: 1. it is macromolecular organic compound, 2. can multiple kenel there be for example liquid solid colloidal solution etc. in it, it can be shaped (moldable), 4. of a great variety, because different monomers and composition thereof can synthesize different plastics, 5. product of many uses presents variation.6. has different character.7. can be with different working methods (processing method), these two nouns of plastics and resin are also often used with.Plastics can be divided into thermoset and thermoplasticity two classes, and the former can't use in refigure, and the latter is duplication of production again and again.The high molecular structure of plastics has two types substantially: first kind is linear structure; Second kind is three dimensional structure.

Summary of the invention

The invention provides a kind of conductive plastics, have having a few of heat-resisting, cold-resistant and conduction.

Technical scheme of the present invention is: described conductive plastics is to be combined by plastic body, softening agent and electro-conductive material, described electro-conductive material is electro-conductive fiber, described plastic body accounts for the 35%-50% of described conductive plastics mass percent, described additive accounts for the 40%-45% of described conductive plastics mass percent, and described electro-conductive material accounts for the 10%-20% of described conductive plastics mass percent.

In preferred embodiment of the present invention, described softening agent is dioctyl terephthalate.

In preferred embodiment of the present invention, described plastic body accounts for 45% of described conductive plastics mass percent, described softening agent accounts for 40% of described conductive plastics mass percent, and described electro-conductive material accounts for 15% of described conductive plastics mass percent.

Embodiment

Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.

Wherein, described softening agent is dioctyl terephthalate, and dioctyl terephthalate (DOTP) is the primary plasticizer of a kind of excellent property of using of polyvinyl chloride (PVC) plastics.It is compared with dimixo-octyl phthalate (DOP) commonly used at present, has advantages such as heat-resisting, cold-resistant, difficult volatilization, anti-extraction, flexibility and electrical insulation capability are good, demonstrates good persistence, anti-soap water-based and low-temperature pliability in goods.Have following characteristic and purposes; 1.DOTP electricity, good in thermal property at PVC plastics electricity alternative DOP in the line sheath, also can be used for the production of leatheroid film.In addition, have good consistency, also can be used for acrylonitrile derivative, the plasticising of polyvinyl butyral acetal, paracril, nitrocellulose etc.And play a part to improve goods hardness and deformability, in goods such as paracril, chloroprene rubber, terpolymer EP rubber, can be used as tenderizer.Being used in especially and having plasticization effect and low volatility preferably on the CABLE MATERIALS, be widely used in and require various goods heat-resisting, high insulation, is that 70 ℃ of CABLE MATERIALS of production heatproof and other require the desirable softening agent of anti-volatilization PVC goods.2.DOTP be used for the PVC goods in the car, can solve the glass vehicle window problem that hazes.DOTP also is used for quality lubricant or the slip additive of paint, coating and the precision instrument of noble furniture and upholstery, zapon varnish auxiliary agent, paper tenderizer, polyesteramide biaxially oriented film, film plastic art ware, blood plasma reservoir bag etc.3. because the thread-like molecule structure of DOTP is similar with DOS, DOA, its winter hardiness is also better.4.DOTP volume specific resistance than the high 10-20 of DOP doubly, and be the transport property excellence.5. because DOTP does not contain phthalate, 16 kinds in European Union and other country's restriction uses do not contain in the phthalic acid softening agent scope, therefore, are a kind of good environment-friendly type softening agent.

Further specify, described electro-conductive material is electro-conductive fiber, and (English: be a kind of new fiber species that occurs the sixties in 20th century electroconductive fiber), it refers to that generally electric conductivity is greater than the fiber of 10-7 Ω-1.cm-1 to electro-conductive fiber.Therefore this fibrid has good electrical conductivity and weather resistance, particularly still has good durable antistatic under low humidity, in field such as industrial, civilian very big purposes is arranged.Used electro-conductive fiber is the electro-conductive fiber of metallic compound type among the present invention, resistivity is 102～104 Ω cm, main employing composite spinning method is sneaked into the electrically conductive particles part of high density in the fiber and is produced, black is the electrically conductive particles carbon black, be as titanium dioxide coating on the weisspiessglanz surface that contains small amounts tin in vain with metal oxide, fiber is lighter relatively, and pliability is arranged, and can wash and be convenient to processing; Also can be by post-treatment chemistry set copper compound or plated metal.

The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
