Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of self-lubricating abrasion-resistant polydiphenyl ether plastics.
Background technology
Plastics can be divided into two types of thermoset and thermoplasticallies, 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 basically: first kind is linear structure, and the macromolecular compound with this structure is called chain macromolecule compound; Second kind is three dimensional structure, and the polymer chemical combination with this structure is called three dimensional polymer.Some polymer has side chain, is called the side chain polymer, belongs to linear structure.Though some polymer is intermolecular to be had crosslinkedly, crosslinked less, is called reticulated structure, belongs to three dimensional structure.
Present stage, the use of plastics is very extensive, wherein ppe be the plastics of main material also be practicality widely one of them; Ppe is the high-strength engineering plastic that grows up 1960's, is called for short PPO, the general ppe that is mainly modification on the market; Be called for short MPPO, perhaps MPPE can improve processing characteristics greatly; Improve stress cracking resistance and impact property, reduce cost, just thermotolerance and gloss slightly reduce.Various working methods such as PPO and MPPO can adopt injection moulding, extrude, blowing, mold pressing, foaming and plating, vacuum plating, printing press processing, because of melt viscosity is big, processing temperature is higher.PPO and MPPO are mainly used in aspects such as electronic apparatus, automobile, household electrical appliance, office equipment and industrial machinery; Utilize MPPO thermotolerance, shock-resistance, dimensional stability, anti-scratch, anti-ly peel off, coating character and electric property, be used to do fascia, radiator grid, loudspeaker grid, supervisory control desk, safety box, relay1 box, junctor, wheel cover; Be widely used in component such as making junctor, coil-winding axle, switch relay, tuner, large-scale electronic console, VC, store battery accessory, microphone in the electronic apparatus industry.Be used for component such as televisor, Kamera, video-tape, sound-track engraving apparatus, air conditioning machinery, warmer, electric cooker on the household electrical appliance.
But, in actual application, find that the self lubricity wear resistance of composite polyphenylene ether has deficiency, considerable influence result of use, range of application, and after using, also there is very big environmental influence problem in the plastics after being dropped.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, provide a kind of and have self lubricity preferably and the self-lubricating abrasion-resistant polydiphenyl ether plastics of wear resistance.
Technical scheme provided by the invention is following: a kind of self-lubricating abrasion-resistant polydiphenyl ether plastics of the present invention, by following composition by weight forming ppe: 35.5-89.5%; Synthetic resins: 8-32%, lubricant: 0.1-3.2%; Wear-resisting properties-correcting agent: 1-24%, inhibitor: 0.3-3.2%; Thermo-stabilizer: 0.1-3.5%; Graphite: 0.5-5.8%; Compatilizer: 0.1-5.9%; Gac: 0.3-5.5%.
The Production Flow Chart of self-lubricating abrasion-resistant polydiphenyl ether plastics of the present invention is: earlier ppe, synthetic resins are processed 60% the aqueous solution; And under the temperature of normal pressure and 30 ℃; In order to make the plastics that make with ppe possess certain self-lubricating property, wear resisting property; Should be with a certain proportion of lubricant, wear-resisting properties-correcting agent, inhibitor, thermo-stabilizer, graphite, compatilizer, wherein lubricant can improve the lubricity of plastics, the wear resisting property of the plastics that wear-resisting properties-correcting agent can improve; The adding of graphite can improve the lubricity and the wear resisting property of plastics simultaneously, makes the performance of plastics improve.After treating these reagent thorough mixing, in another vessel, stir, stir after 10 minutes; Can obtain the mixing solutions of other reagent, under temperature is 65 ℃ temperature, dry then, guarantee that particle and powder are even basically; Do not have obvious agglomerate or gather, cooling then is with active carbon purifying, filtration; Obtain 30% salts solution this moment, and the mixing solutions of the synthetic resin solution of salts solution with 30% and 60% ppe obtains raw material behind 105 ℃ of following prepared in reaction ppe, synthetic resins powder; 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 the self-lubricating abrasion-resistant polydiphenyl ether plastics again.
The advantage of self-lubricating abrasion-resistant polydiphenyl ether plastics of the present invention: except with existing injection molding level polyphenylether has identical performance; Through lubricant, wear-resisting properties-correcting agent and be the adding of touching; Solve some plastics self-lubricating properties and the insufficient problem of wear resisting property thereof on the present market; This product environmentally safe in equivalents, has improved the competitiveness of product in market so greatly in addition.
Embodiment
Below be the most preferred embodiment of self-lubricating abrasion-resistant polydiphenyl ether plastics raw material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of self-lubricating abrasion-resistant polydiphenyl ether plastics is provided, by following composition by weight forming ppe: 58.1%; Synthetic resins: 15.8%, lubricant: 2.5%; Wear-resisting properties-correcting agent: 10.5%, inhibitor: 2.8%; Thermo-stabilizer: 1.8%; Graphite: 3.6%; Compatilizer: 2.8%; Gac: 2.1%.
Earlier with ppe, synthetic resins as in the vessel, ppe, synthetic resins are processed 60% the aqueous solution, and under the temperature of normal pressure and 30 ℃; A certain proportion of lubricant, wear-resisting properties-correcting agent, inhibitor, thermo-stabilizer, graphite, compatilizer are blended in another vessel and stir, stir after 10 minutes, can obtain the mixing solutions of other reagent; Under temperature is 65 ℃ temperature, dry then, guarantee that particle and powder are even basically, do not have obvious agglomerate or gather; Cooling then with active carbon purifying, filtration, obtains 30% salts solution this moment; The mixing solutions of salts solution with 30% and 60% ppe, synthetic resin solution obtains raw material behind the synthetic resins powder of 105 ℃ of following prepared in reaction ppe, 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 the self-lubricating abrasion-resistant polydiphenyl ether plastics again.
