Abstract
The invention relates to a lead-free anti-flaming X-ray shielding high polymer elastomer. Industrial solid waste residue which is discharged after aluminum oxide is refined from bauxite by adopting the bayer's method, processed red mud, other metallic oxides and salts, and rubber and plastics which are added with a certain proportion are mixed to form a rubber high polymer elastomer, and then flame retardants are added in the rubber high polymer elastomer, so as to obtain the lead-free anti-flaming X-ray shielding high polymer elastomer. The shielding property, the flame retardance, high temperature resistance and mechanical property of the material completely reach ideal effect. The lead-free anti-flaming X-ray shielding high polymer elastomer can be widely applied to medical diagnostic X-ray machines, X-ray diffractometers, emitters of electron microscopes and the protection for working personnel in X-ray generated occasions, and can be further applied to equipment requiring for ray shielding, corrosion resistance and high-temperature resistance and building materials.
Description
Technical field: the present invention relates to a kind of unleaded fire-retardant X ray shielding macromolecular elastomer.Be widely used in the occasion staff's that the projector of medical diagnosis X radial ray machine, X-ray diffractometer, electron microscope and other produce with X ray protective material, and be applied in other big area and need shield in ray, anticorrosion and resistant to elevated temperatures equipment and the material of construction.
Background technology: the development of ray protection material, produce and apply, be one of emphasis of civilian healthy prevention work, also be the nuclear energy development field, the important component part of military domain radiation protection.State's inner macromolecule antiradiation material is mainly based on rubber item.States such as America and Europe, Japan have succeeded in developing novel thermoplastic elastomer composite material, and this matrix material has the physical and mechanical properties height mutually on year-on-year basis under the condition of protective value, surface property is good, ageing-resistant, excellent properties such as dimensional stabilizing can also the heat seal ready-made clothes.Under the condition of identical weight,, can also improve the work-ing life and the shielding property of material to a certain extent if use urethane as base material.Develop the related production technology abroad, prepared very thin sheet material (minimum thickness can reach 0.3mm).The quite soft based sheet of the personal protection clothing of the compound manufacturing of single or multiple lift mainly is used to make protection jacket, vest, radioprotective clothings such as integral protection clothing, its shortcoming be discrete state material still based on lead, and cost an arm and a leg.
Russ P RU2054439, RU2028331 disclose the rubber X-ray-preventing matrix material with the modification of inorganic rare earth oxide filler, but because inorganic rare earth (rare earth oxide) and rubber matrix is compatible relatively poor, therefore at itself and polymeric matrix the space appears easily at the interface, these spaces will be easy to be passed through when energetic ray shines, even the phenomenon that ray occurs leaking, the shielding homogeneous performance of material also is difficult to guarantee, so the stability of material also is difficult to control.
Chinese patent 200410096790.4 discloses a kind of rare earth modified full non-lead X-ray screen rubber, though also play certain protective effect, but in the lanthanide metal oxide filler of its use, the metal that has is a radioactive metal, as the samarium metal in the Samarium trioxide is radioactive metal just, as can not complete oxidation or oxidation not thorough, samarium metal will radiate ray, and human body is produced harm.
Summary of the invention: the purpose of this invention is to provide a kind of unleaded fire-retardant X ray shielding macromolecular elastomer, be to adopt bayer's process to refine the industrial solid waste residue of discharging behind the aluminum oxide in the bauxite, product red mud after processing, with other metal oxide and its esters, in the rubber and plastic macromolecular elastomer that adds rubber and plastics by a certain percentage and form with blend, add ignition dope, thereby obtain a kind of unleaded fire-retardant X ray shielding macromolecular elastomer, make shielding, flame retardant resistance, high thermal resistance, the mechanical property of material all reach the ideal effect.
Technical scheme of the present invention is: a kind of unleaded fire-retardant X ray shielding macromolecular elastomer, and it is characterized in that: it is formed and parts by weight are:
Described macromolecular elastomer is meant rubber and plastics and makes with blend.
Wherein, described red mud is to adopt bayer's process to refine the industrial solid waste residue of discharging behind the aluminum oxide from bauxite, and after processing, its particle diameter reaches more than 2000 orders.
Described metal oxide is meant deleading, mercury, the metal oxide outside, arsenic, group of the lanthanides, actinium series and radioelement and composition thereof.
Described fire retardant is clorafin, antimonous oxide or Triphenyl phosphate (TPP).
Because adopt technique scheme, major ingredient of the present invention is macromolecular elastomer, red mud, metal oxide.Because red mud refines the industrial solid wastes of discharging behind the aluminum oxide for adopt bayer's process from bauxite, the product after processing, its particle diameter is more than 2000 orders, its main component is Fe
2O
3, SiO
2With metal oxides such as calcium, aluminium, magnesium, titanium, sodium; Red mud has significant heat stabilization to plastics (especially PVC), and has reached and be uniformly dispersed and the good interface consistency; Make shielding, flame retardant resistance, resistance to deterioration, the mechanical property of material all reach the ideal effect; Simultaneously, red mud is to refine the waste residue that produces after the aluminum oxide from bauxite, China's red mud output in 2007 is above 3,000 ten thousand tons, main processing mode is built a dam and is stored up at present, need occupy large stretch of soil, and surrounding enviroment are easily caused severe contamination, and the further utilization of red mud both can be alleviated environmental pollution, can increase the performance of enterprises again.The present invention can be widely used in projector and other protection with the occasion staff of X ray generation of medical diagnosis X ray ray machine, X-ray diffractometer, electron microscope, needing in shielding ray, anticorrosion and resistant to elevated temperatures equipment and the material of construction also to may be used on.
The preparation of the unleaded fire-retardant X ray shielding macromolecular elastomer of the present invention need not special equipment, uses rubber tooling commonly used such as mill, Banbury mixer to get final product.The processing condition of its refining glue are that rubber and plastics are placed the high temperature rubber mixing machine, and temperature is 100-150 ℃, and after plasticating 10 minutes, it is standby that macromolecular elastomer is made in following sheet cooling; Again at normal temperatures, in Banbury mixer, add macromolecular elastomer, start Banbury mixer, add zinc carbonate, Zinic stearas, anti-aging agent model then successively and be 2246 or MB, red mud, metal oxide, dioctyl phthalate or chlorinated paraffinic oil, fire retardant, discharge when temperature to be expected reaches 90 ℃, adding, TM monex TD and vulcanizing agent DTDM in mill mix after 3 minutes at last, play the triangle bag 6 times, make matrix material.
