The invention discloses high-temperature resistant plastic. The high-temperature resistant plastic is composed of a plastic body, synthetic fibers and a non-intermetallic compound, wherein the synthetic fibers are high temperature nylon, the plastic body accounts for 40-50% by weight of the high-temperature resistant plastic, the synthetic fibers account for 30-35% of the high-temperature resistant plastic, and the non-intermetallic compound accounts for 20-25% of the high-temperature resistant plastic. The high-temperature resistant plastic provided by the invention has the advantages of high heat resistance.
Description
Technical field
The present invention relates to a kind of high-temperature resistance plastice, relate in particular to a kind of industrial high-temperature-resistant plastics.
Background technology
Plastics are synthetic macromolecular compound { polymkeric substance (polymer) }, can be described as again polymer or giant molecule (macromolecules), also be plastics (plastics) or the resin (resin) that generally is commonly called as, 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 are a kind of material take high-molecular-weight organic material matter as main component, 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, it can be multiple kenel exist such as liquid solid colloidal solution etc., 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: the first is linear structure; The second is three dimensional structure.
Summary of the invention
The invention provides a kind of high temperature material, have advantages of that resistance toheat is high.
Technical scheme of the present invention is: described high-temperature resistance plastice is to be formed by plastic body, synthon and nonmetal compound combination, described synthon are high-temperature nylons, described plastic body accounts for the 40%-50% of described high-temperature resistance plastice mass percent, described synthon account for the 30%-35% of described high-temperature resistance plastice mass percent, and described nonmetal compound accounts for the 20%-25% of described high-temperature resistance plastice mass percent.
In a preferred embodiment of the present invention, described nonmetal compound is phosphatization silicon.
In a preferred embodiment of the present invention, described plastic body accounts for 45% of described high-temperature resistance plastice mass percent, described synthon account for 35% of described high-temperature resistance plastice mass percent, and described nonmetal compound accounts for 20% of described high-temperature resistance plastice mass percent.
Embodiment
The below is described in detail preferred embodiment of the present invention, 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 high-temperature nylon is commonly called as PPA, has excellent over-all properties, aspect heat, electricity, physics and the chemical resistant properties good performance is being arranged.Particularly at high temperature still have high rigidity and high strength and splendid dimensional precision and stability, this is so that HTPA has widely application prospect in fields such as automobile, electric, mechanical engineerings.HTPA has good processibility, can adopt traditional injection moulding machine and mould to carry out forming process.HTPA can carry out in response to guest's demand enhancing on some physical property or the change on the color, and can provide that glass strengthens, the product of the various grades such as fire-retardant.Also has the outstanding resistance to elevated temperatures of following characteristic 1., 2. still have high rigidity, high strength under the high temperature, 3. splendid dimensional precision and stability and low warpage properties, 4. good chemical resistant properties, 5. affected by water-intake rate minimum for physical property, 6. good surface quality, easy-formation.
Further specify, silicon carbide (SiC) is to be that raw material forms by the resistance furnace pyrotic smelting with quartz sand, refinery coke (or coal tar), wood chip.Silicon carbide also exists rare mineral, Mo Sangshi at the Nature.Silicon carbide claims again moissanite.In the non-oxidized substance hi-tech refractory raw materials such as contemporary C, N, B, silicon carbide is most widely used general, most economical a kind of.Can be called powder emery or fire sand.Silicon carbide is to form through pyrotic smelting in resistance furnace with raw materials such as quartz sands, refinery coke (or coal tar), wood chip (when producing green silicon carbide need to salt).At present the industrial silicon carbide of China is divided into two kinds of black silicon carbide and green silicon carbides, is hexagonal, and proportion is 3.20～3.25, and microhardness is 2840～3320kg/mm2.Silicon carbide has 70 kinds of crystalline forms at least.Alpha-silicon carbide is modal a kind of Polymorphism, forms being higher than under 2000 ° of C high temperature, has hexaplanar crystal structure (like wurtzite).Silicon B-carbide, cubic crystal structure, similar to diamond, then be lower than 2000 ° of C generations.Although in the application of out-phase catalyst carrier, to have the per surface area higher than α kenel noticeable because of it, until today, this kenel not yet has commercial application.Because of its proportion of 3.2 and high sublimation temperature (approximately 2700 ° of C), silicon carbide is well suited for the raw material object as bearing or High Temperature Furnaces Heating Apparatus.Under any pressure that can reach, it can not melt, and has quite low chemically reactive.Because its high heat conductance, high collapse strength of electric field and high maximum current density, in the application of semi-conductor high power element, many people try to replace silicon [1] with it.In addition, it and microwave radiation have very strong coupling, and its all high sublimation point, make it can be applied to heating of metal.Pure silicon carbide is colourless, and the palm fibre of industrial production is to the impurity of black system owing to iron content.Gloss on the crystal as the rainbow then is because due to the silicon dioxide layer of protection of its surface generation.
The specific embodiment of the present invention; but protection scope of the present invention is not limited to this; 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.
