Description
It is good to the present invention relates to physical strength, can shield the leaded synthetic glass composition and the manufacture method thereof of low energy (wavelength comparatively long) x ray and ultraviolet transparent or colored transparent.
As everyone knows, stereotype and leaded very high unorganic glass all can conduct be prevented the severe radiation shielding material, but the stereotype anharmonic ratio is heavy high, opaque price height.Though the unorganic glass that lead tolerance is high is transparent, crisp and frangible, proportion is also higher, can't make the larger area shielding material, inconvenient again processing of cutting.
In order to overcome the shortcoming of above-mentioned two kinds of anti-radiation shielding materials, found out the anti-severe radiation shielding material of the synthetic glass that contains a large amount of lead.Excellent comprehensive performances such as this material has light weight, is easy to machine-shaping, and is transparent.The relevant document of this respect is a lot, and they are that the Japanese documentation spy opens clear 53-9995, and the spy opens clear 53-9996, and the spy opens clear 53-66310, and the spy opens clear 54-1797, and the spy opens clear 55-151005 etc.
Chinese patent literature CN85100239A has proposed the two step polymerization techniques that mass polymerization is carried out in a kind of first prepolymerization then, makes the method for anti-x ray synthetic glass.This method is with leaded monomer and non-leaded monomer, leaded and non-leaded interpolation component and initiator, softening agent, releasing agent, oil-soluble colourant etc., and uniform mixing carries out copolyreaction and obtains suitable crosslinked copolymers macromolecular structure.This control of product lead content 10～40%.Initiator amount is 0.02-1%.This method has significantly and shortens the cycle, and reaction evenly is easy to control the purity of product, the advantage of seepage when reducing injection molding.
Along with science and technology development, robot calculator has obtained developing rapidly, all departments are widely used in national economy, household electrical appliance enter into every family, the window of tube of robot calculator and televisor has become low energy x ray (the x ray that wavelength is long) and ultraviolet emissive source, human body is caused to a certain degree harm, especially the operator of robot calculator are nearer from window of tube, operate for a long time, be subjected to the low energy x ray that window of tube emits, the stimulation of ultraviolet ray and forceful rays and flicker, operator's face especially eyes is caused bigger stimulation, make operator produce ophthalmodynia, tired, the sensation that headache etc. are uncomfortable makes face color spot occur sometimes.Therefore low energy x ray and the ultraviolet absorption protection that the robot calculator window of tube is radiated out just become the current important topic that must solve with the elimination intense light with the stimulation of glimmering to human eye.
In addition, because the low energy x ray that nature exists, various light such as ultraviolet ray have fading function to historical relic, need work out both transparently, can avoid historical relic again and fade, and can make public a kind of protection historical relic material from viewing and admiring again.
The synthetic glass that the method that Chinese patent literature CN85100239A proposes is produced, because the lead content height, proportion is still bigger, and mechanical property is also relatively poor, it is easily broken to add man-hour, transparency is unsuitable for using in the preceding protection of robot calculator, does not contain UV light absorber, can not absorb ultraviolet ray fully, this production technique is because used releasing agent is stearic acid or silicone oil in addition, be difficult for the demoulding, product appearance is poor, and used processing condition are not good.
It is low that purpose of the present invention just is to work out a kind of lead tolerance, proportion is little, and good mechanical property is easy to process difficult broken, the synthetic glass composition that uses was gone up in protection before transparency was suitable for comvision machine window of tube, made this product can shield low energy x ray and can absorb ultraviolet ray fully again.
Another object of the present invention, be that this product can make the staff of prolonged operation before the computer window of tube exempt ultraviolet ray of low energy x ray and the forceful rays that window of tube radiates out and flicker is facial to operator and the stimulation of eyes, eliminate the sensation of operator's discomforts such as ophthalmodynia, fatigue, headache.
Another purpose of the present invention is to find out a kind of new releasing agent to make product be easy to the demoulding, and product appearance is attractive in appearance.
Further object of the present invention is the good processing condition that work out two step polymerizations.
The present invention is a kind of anti-low energy x ray and ultraviolet synthetic glass composition, and this synthetic glass composition is 0.02-0.3% wherein a kind of of initiator benzoyl peroxide, Diisopropyl azodicarboxylate, dicumyl peroxide, cyclohexanone peroxide.(weight percentage, as follows) and releasing agent, oil-soluble colourant (0～5 * 10
-2%) exist down, with methyl acrylate, ethyl propenoate, propyl acrylate, butyl acrylate, the vinylformic acid glycol ester, methyl methacrylate, Jia Jibingxisuanyizhi, propyl methacrylate, butyl methacrylate, wherein a kind of of methacrylic acid glycol ester is that monomer is as main component and plumbous organic compound propylene lead plumbate, the methacrylic lead plumbate, methylene-succinic acid lead, plumbic acetate, lead naphthenate, lead octoate 36, the isobutyl lead plumbate, lead laurate, palmitoleic acid lead a kind of 0.5-10% and methacrylic acid-2-hydroxy methacrylate wherein, methacrylic acid-2-hydroxy propyl ester, 2-Hydroxy ethyl acrylate vinylformic acid-2-hydroxy propyl ester wherein a kind of 0～30%, softening agent is a dibutyl phthalate, dioctyl phthalate (DOP), the material that a kind of 0～15% the polymkeric substance wherein of dioctyl sebacate is formed, synthetic glass composition of the present invention also contains UV light absorber, and said releasing agent is a nonionogenic tenside Span 60 ester, the Span 20 ester, soft ester acid herbal tea alcohol ester, the Span 80 ester, sorbitan monostearate, the lauric acid sorbitan ester, the Palmiticacid sorbitan ester, the oleic acid sorbitan ester, wherein a kind of of Polysorbate 20 ester.
