СПОСОБ ПЛАСТИФИКАЦИИ ПОЛИВИНИЛХЛОРИДАMETHOD OF PLASTIFICATION OF POLYVINYLCHLORIDE
Изобретение относитс к переработке пластмасс .The invention relates to the processing of plastics.
Известны способы пластификации полиВИнилхлорида «ндивидуальвыми галогензаменценными ароматическими соединени ми, наприМер /г-дихлордифенилметаиом.Known methods for plasticizing polyvinyl chloride are halogen-substituted aromatic compounds, for example, g / d-dichlorodiphenylmeta.
По предлагаемому способу в качестве пластификаторов прим ен ют смесь, содержащую 60-70% 2,2-дихлорд1ифенилдихлорметилметана и 30-40% 2,4-дихлордифеиилхлорэтена или смесь, содержащую 25-40% 2,2-диэт,илдифенилдихлор метил мета на, 15-20% 4,4диэтилдифенилдихлорметилметана и 40-60% 2,4-ДИэтилдифенИлдихлорметил метана.According to the proposed method, a mixture containing 60-70% of 2,2-dichlorodiphenyldichloromethylmethane and 30-40% of 2,4-dichlorodifeiylchloroethene or a mixture containing 25-40% of 2,2-diet, ildiphenyldichloromethyl methane, 15-20% 4,4 diethyl diphenyl dichloromethyl methane and 40-60% 2,4-Diethyldiphenyl dichloromethyl methane.
Пример 1. Поливинилхлоридную смолу смещивают с пластификатором «ЗД, представл ющим собой смесь 2,2-дихлордифенилдихлорметилметана .и 2,4-дихлордифенилхлорэтена при 20°С.Example 1. A polyvinyl chloride resin is displaced with a plasticizer DF, which is a mixture of 2,2-dichlorodiphenyldichloromethylmethane and 2,4-dichlorodiphenylchloroethene at 20 ° C.
Выдерживают смесь в течение суток при 20°С и затем вальцуют .при ПО-130°С 10- 15 мин..Maintain the mixture for a day at 20 ° C and then roll. For PO-130 ° C for 10 to 15 minutes.

Пример 2. Поливинилхлоридную смолу смещивают с пластификатором «ПР, представл ющим собой смесь 2,2-диэтилднфенилдихлорметилметайа , 4,4-диэтилдифенилдихлорметилметана и 2,4-диэтилдифенилдихлорметилметана при 20°С. Выдерживают смесь суткИ при 20°С и затем вальцуют при 110 130°С в течение 10-15 мин.Example 2. Polyvinyl chloride resin is displaced with the plasticizer PR, which is a mixture of 2,2-diethylnphenyldichloromethylmethia, 4,4-diethyldiphenyldichloromethylmethane and 2,4-diethyldiphenyldichloromethylmethane at 20 ° C. Maintain the mixture day at 20 ° C and then roll at 110–30 ° C for 10–15 min.
