Description
Technical field
The present invention relates to a kind of plastic formula, be specifically related to a kind of high-density plastic's prescription.
Background technology
It is blue that the fully synthetic plastics of the first come from American Belgian Lie Ao Hendric Bake, and on July 14th, 1907, he has registered the patent of phenoplast.The Bake orchid is shoe maker and maid servant's son, is born in Ghent, Belgium in 1863.1884,21 years old Bake orchid obtained the University of Ghent doctorate, just becomes the physics and chemistry professor of the colleges of education such as Belgian Bu Luri height in the time of 24 years old.1889, just married the tutor's of university daughter, the Bake orchid obtains again a traveling fellowship, is engaged in chemical research to the U.S..Strangle under professor's encouragement at the charles Qian De of Columbia University, the Bake orchid is stayed the U.S., is New York photography supplier work.This makes him invent the Velox developing out paper after several years, and this printing paper can rather than must could develop under light in the sun.1893, the blue resignation in Bake established Nepera chemical company.Under product innovation impacted, photographic goods merchant Eastman Kodak Company had been unable to stand.1898, through twice negotiation, the patent right that the Velox developing out paper is buied with the price of 750,000 dollars (being equivalent to present 1,500 ten thousand dollars) by Kodak side.But Kodak finds that very soon prescription is ineffective, and the answer of Bake orchid is: this is very normal, and the inventor can omit several steps in patent document, in case used by infringement.Kodak is apprised of: what they bought is patent, but is not the A to Z of.Paid again 100,000 dollars, Kodak knows secret in a kind of solution.Dig to get start-up capital, the luxurious house of looking down the Hudson River that the Bake orchid had been bought near the Yang Kesi in New York makes a granary into self-contained private laboratory, also cooperates with people to build up pilot plant at Brooklyn.The great market of insulating material is being contained in the at that time power industry of just rudiment.First temptation that the Bake orchid smells is skyrocketing of natural insulating material shellac price, and for centuries, this material relies on the cottage industry production in South Asia always.Through investigating, the blue substitute seeking shellac in Bake is as first business goal.At that time, the chemist had begun to recognize that the natural resin and the fiber that much can be used as coating, tamanori and fabric all were polymkeric substance, i.e. the macromole that repeats of structure, begin to seek can synthetic polymer composition and method.As far back as 1872, Germanization scholar Adaofu Feng Baier just found: behind phenol and the formaldehyde reaction, and some obstinate residue of Glass tubing bottom.But the eye of Baeyer is on synthetic dyestuff, rather than on the insulating material, concerning him, the insoluble matter of this sticky paste is the bar blind alley.Concerning the Bake orchid was waited the people, this thing but was bright road sign.Since 1904, this reaction that begins one's study of Bake orchid.What obtain at first is a kind of liquid--P-F shellac, be called Novolak, but market and unsuccessful.After 3 years, he obtains a kind of stickies of pasty state, becomes translucent duroplasts--phenoplast after the mold pressing.Different is that zylonite finishes complete synthesis plastics from the collodion of chemical treatment and the vegetable material of other cellulose and phenoplast are the first in the world.The Bake orchid with its with oneself naming be " Berlet " (Bakelite).He is very lucky, and Britain colleague James Swinburne jazz only submitted patent application in late one day than him, otherwise phenoplast are " this Wenbo Lai Te " possibly in the English.On February 8th, 1909, the Bake orchid discloses this plastics in a meeting of New York branch of american chemical association.
Summary of the invention
The object of the present invention is to provide make the high-density plastic who makes have chemical stabilization, can not corrosion, shock-resistance is good and a kind of high-density plastic's of the potent fruit of density prescription.
Technical scheme of the present invention is: a kind of high-density plastic's prescription, comprise polyether-ether-ketone, dispersion agent, vulcanizing agent and fire retardant, described dispersion agent is polyoxymethylene, vulcanizing agent is resol, fire retardant is chloroprene rubber, and each composition weight proportion is that polyether-ether-ketone accounts for 62%-66%, and polyoxymethylene accounts for 14%-16%, resol accounts for 1%-2%, and chloroprene rubber accounts for 19%-20%.
In a preferred embodiment of the present invention, described polyoxymethylene comprises polyoxymethylene.
In a preferred embodiment of the present invention, each composition weight proportion of described high-density plastic's prescription is that polyether-ether-ketone accounts for 64%, and polyoxymethylene accounts for 15%, and resol accounts for 1%, and chloroprene rubber accounts for 20%.

Embodiment
Below in conjunction with 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.
In one embodiment, a kind of high-density plastic's prescription, comprise polyether-ether-ketone, dispersion agent, vulcanizing agent and fire retardant, described dispersion agent is polyoxymethylene, and vulcanizing agent is resol, fire retardant is chloroprene rubber, each composition weight proportion is that polyether-ether-ketone accounts for 62%-66%, and polyoxymethylene accounts for 14%-16%, and resol accounts for 1%-2%, chloroprene rubber accounts for 19%-20%, and described polyoxymethylene comprises polyoxymethylene.
Further specify, each composition weight proportion of described high-density plastic's prescription is that polyether-ether-ketone accounts for 64%, and polyoxymethylene accounts for 15%, and resol accounts for 1%, and chloroprene rubber accounts for 20%,
Can debug according to different ratios according to different demands, thereby reach different results of use, and polyether-ether-ketone contains the superpolymer that the repeating unit of a ketonic bond and two ehter bonds consists of, belong to the speciality polymer material and have the effect of chemical stabilization.
Polyoxymethylene is the polymkeric substance that repeating unit is.Excellent rigidity is arranged, and is important engineering plastics, smooth surface, and glossiness hard and fine and close material has the strong effect of density.
Resol is that an important application is exactly as binding agent.A kind of multi-functional, with various organic and mineral fillers can both be compatible material, be approximately in temperature under 1000 ℃ the inert gas conditions, resol can produce very high carbon residue, this is conducive to keep the structural stability of resol.This specific character of resol also is the major reason that it can be used for fire resisting material field, therefore has the effect of chemical stabilization.
And chloroprene rubber is all with emulsion polymerization production, and the technological process of production mostly is single still batchwise polymerization.Polymerization temperature is multi-control at 40～60 ℃, and transformation efficiency is then about 90%.Polymerization temperature, final transformation efficiency is too high or polymerization process in enter air (oxygen) and all can cause quality product to descend.Use sulphur-thiuram (tetraalkyl methylamino-thion disulphide) system Molecular regulator amount in the production.The main drawback of sulphur-thiuram system is that sulfide linkage is stable not, and this is one of major reason of impact storage property.If with mercaptan Molecular regulator amount, then can improve this kind performance.Chloroprene rubber is different from general synthetic rubber, and it is without sulfur cross-linking, but plays the high effect of intensity with sulfurations such as zinc oxide, magnesium oxide, it have not can corrosion effect.The invention provides a kind of high-density plastic, have chemical stabilization, can not corrosion, shock-resistance is good and density is strong effect.
