Description
Известен способ модификации поверхности химической прививкой полимеров, например обработкой смеси наполнител и соответствующего мономера в вибромельнице.There is a method of surface modification by chemical grafting of polymers, for example, by treating a mixture of a filler and the corresponding monomer in a vibrating mill.
Также известно получение привитых полимеров из винилхлорида, акрилонитрила и метилметакрилата радиацией на органической основе.It is also known to obtain graft polymers from vinyl chloride, acrylonitrile and methyl methacrylate by organic-based radiation.
Предлагаетс способ модификации минеральных тел образованием на их поверхности тонкого сло полимера из виниловых мономеров под действием ионизирующих излучений.A method is proposed for modifying mineral bodies by forming on their surface a thin polymer layer of vinyl monomers under the action of ionizing radiation.
В качестве .мономеров примен ют метилметакрилат, акрилонитрил и винилхлорид. Основой дл получени привитых полимеров служит углеродна сажа и порощкообразна окись магни .Methyl methacrylate, acrylonitrile and vinyl chloride are used as monomers. The basis for the graft polymers is carbon black and powdered magnesium oxide.
Предлагаемый способ получени привитых полимеров на минеральных телах действием ионизирующего излучени на минеральные тела и пары мономера не известен.The proposed method for obtaining graft polymers on mineral bodies by the action of ionizing radiation on mineral bodies and monomer pairs is not known.
Результатом ионизирующего излучени вл етс активирование поверхности модифицируемого вещества, про вл ющеес в хорошей адгезии ее к различного рода полимерным средам, что способствует повыщению качества изделий, получаемых из смесей, содержащих модифицированный наполнитель.The result of ionizing radiation is the activation of the surface of the modified substance, which is manifested in its good adhesion to various kinds of polymeric media, which contributes to the improvement of the quality of products obtained from mixtures containing modified filler.
Пример 1. 20 г углеродной сажи облучают в присутствии паров метилметакрилата при 70° в течение 10 час на электронном ускорителе при мощности дозы пор дка 2.10 эв/см сек. После облучени на саже образуетс 1,5 вес. % полимера, не удал емого растворител ми.Example 1. 20 g of carbon black are irradiated in the presence of methyl methacrylate vapors at 70 ° for 10 hours at an electron accelerator with a dose rate of about 2.10 eV / cm sec. After irradiation on soot, 1.5 wt. % polymer not removable by solvents.
Пример 2. 20 г углеродной сажи облучают в присутсгвии паров акрилонитрила в течение 13 час в тех же услови х. На саже образуетс около 10 вес. % нерастворимого полимера.Example 2. 20 g of carbon black is irradiated in the presence of acrylonitrile vapor for 13 hours under the same conditions. About 10 wt. % insoluble polymer.
Пример 3. 20 г углеродной сажи облучают при 20° в присутствии паров винилхлорида в тех же услови х. На саже образуетс около 2 вес. % нерастворимого полимера.Example 3. 20 g of carbon black are irradiated at 20 ° in the presence of vinyl chloride vapor under the same conditions. On soot, about 2 wt. % insoluble polymer.

Пример 4. 11 г порошкообразной окиси магни облучают при 70° в присутствии паров метилметакрилата ь тех же услови х в течение 11. час. На частицах окиси магни образуетс 100 вес. % нерастворимого полимера., , Example 4. 11 g of powdered magnesium oxide is irradiated at 70 ° in the presence of methyl methacrylate vapors under the same conditions for 11. hour. On particles of magnesium oxide, 100 wt. % insoluble polymer.,,
