Abstract

The invention relates to an organic high polymer composite material, more specifically to graphite filling plastic, comprising the following components by weight ratio: 55.5-90% of silane ether resin, 0.2-1.5% of external lubricant, 5-27% of graphite powder, 0.5-6.5% of fire retardant, 0.3-3.8% of antioxidant, 0.1-3.0% of stearate, 0.1-0.8% of coupler 0.5-3.5% of cuprammonia complexer, and 0.3-5.5% of active carbon. The graphite filling plastic is environmental-friendly and free from halogen and is filled by graphite based on comprehensive performance of original filled silane ether resin so that the lubricating performance of the product made by the silane ether resin is greater with better wear-resisting property, and improves the chemical property of the silane ether resin effectively.

Description

Graphite-filled plastic

Technical field

The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of graphite-filled plastic.

Background technology

The state plastics industry has formed the more complete industrial system of class through secular struggle with towards the opening in the whole world, 5-15 from now on, and materials for construction will become new consumption hotspot and point of economic increase.Progressively seriation of kind, supportingization and stdn along with the plastic building goods; The requirement of environmental protection and energy saving and putting more effort of applying, the demand of various plastics tubings, door and window, high polymer waterproof material, decorating and renovating material, lagging material and other building plastic goods will have by a relatively large margin to be increased.

The silicon ether resin is to use one of several kinds of maximum engineering plastics at present; His amide group has polarity; In his structure, has well-set hydrogen bond; Make that the fusing point of silicon ether resin is higher, have good physical and mechanical property and wear resistance and self lubricity, these comprehensive characteristics are that other plastics are not available.

But the water-absorbent of ordinary silicon ether resin is big, and shock strength is on the low side before the suction, and suction back rigidity declines to a great extent again, shortcoming such as size instability simultaneously, thus limited the application of silicon ether resin, and then dwindled downstream industry design engineer's selection leeway again.Not only since silicon ether resin but also be the crystal type material when moulding, produce big internal stress easily, thereby cause the uncertainty of final product performance.Simultaneously, can effectively significantly reduce frictional coefficient, simultaneously the stronger component of starting material self wear resistance for requiring.

Summary of the invention

The objective of the invention is to effectively overcome the defective of prior art, the graphite-filled plastic raw material that a kind of environmental protection is provided and has good self lubricity and wear resistance.

Technical scheme provided by the invention is following: a kind of graphite-filled plastic of the present invention, by following composition by weight forming silicon ether resin: 55.5-90%, external lubricant: 0.2-1.5%; Graphite Powder 99: 5-27%; Fire retardant: 0.5-6.5%; Inhibitor: 0.3-3.8%; Hard acid ester salt: 0.1-3.0%; Coupling agent: 0.1-0.8%; Cuprammonium complexing: 0.5-3.5%; Gac: 0.3-5.5%.

Graphite-filled plastic Production Flow Chart of the present invention is: earlier the silicon ether resin is mixed with 60% the aqueous solution, again under the temperature of normal pressure and 60 ℃, in order to make plastics possess certain wear resisting property and lubricity; Should be in 60% the aqueous solution, add a certain proportion of lubricant, Graphite Powder 99, fire retardant, inhibitor, hard acid ester salt, coupling agent, with these reagent thorough mixing in another vessel; And stir, when stirring, also need add quantitative cuprammonium complexing, certain catalyzer has been played in the cuprammonium complexing here; Can after stirring 10 minutes, can obtain the mixing solutions of silicon ether resin so that the time of reflection shortens; Then temperature be under 90 ℃ the temperature with the mixing solutions oven dry of silicon ether resin, cooling is removed impurity with active carbon purifying then; With dilute alkaline soln immersion, washing, dry, granulation, obtain raw material this moment again, and raw material are put into the wall thickness uniformity, draw taper becomes 55 °; Adopt the active energy beam irradiation to solidify in the mould as resist on the molded article surface; Heating and pressurizing, the high-temperature calcination dehydration, cooling obtains graphite-filled plastic again.

The advantage of a kind of graphite-filled plastic of the present invention: fill with graphite; Make that the lubricity of the product that the silicon ether resin is made is higher, wear resisting property also improves thereupon, and effectively raises the chemical property of silicon ether resin; Make the plastics of processing with the silicon ether resin possess lubricity; Specious, can not produce scratch even use for a long time simultaneously yet, promptly wear resisting property is stronger.

Embodiment

Below be the most preferred embodiment of graphite-filled plastic raw material of the present invention, therefore do not limit protection scope of the present invention.

Embodiment one, and a kind of graphite-filled plastic is provided, by following composition by weight forming the silicon ether resin: 79%, external lubricant: 0.7%; Graphite Powder 99: 8.2%; Fire retardant: 3.8%; Inhibitor 2.7%; Hard acid ester salt: 1.2%; Coupling agent: 0.6%; Cuprammonium complexing: 1.7%; Gac: 2.1%.

Below be the principle of work of present embodiment:

Earlier the silicon ether resin is mixed with 60% the aqueous solution, under the temperature of normal pressure and 60 ℃, is blended in another vessel and stirs again with a certain proportion of external lubricant, Graphite Powder 99, fire retardant, inhibitor, hard acid ester salt, coupling agent; The adding of wherein hard acid ester salt be played prevent when some plastics because be heated, the effect of light or oxygen, thereby degrade prematurely, oxidative cleavage, the crosslinked phenomenon that material property is degenerated, in reaction process, also need add quantitative cuprammonium complex catalyst; Stir after 10 minutes, can obtain the mixing solutions of silicon ether resin, under temperature is 90 ℃ temperature, dry then; Active carbon purifying is used in cooling then, again with dilute alkaline soln immersion, washing, dry, granulation; Obtain raw material this moment; Raw material are put into the wall thickness uniformity, draw taper becomes 55 °, adopt the active energy beam irradiation to solidify in the mould as resist heating and pressurizing on the molded article surface; The high-temperature calcination dehydration, cooling obtains graphite-filled plastic again.

The above; Be merely 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 technical scope that the present invention disclosed, 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.
