Description
Известен способ получени цикл(,каучука циклизацно Heii.i;icnKJ3iiцированного каучука в фенольном растворе в присутствии кислот. известно исиользование циклокаучука совместно с модифицированными фенольноформальдегидными, или малеиновыми. ii.iii алкидными смолами дл закреплени на ме чованно однако такое закрепление требует времени около 120-300 сек.A known method of obtaining a cycle (rubber cyclizing Heii.i; icnKJ3ii rubber in a phenolic solution in the presence of acids. It is known to use a cyclo-rubber together with modified phenol-formaldehyde or maleic. Ii.iii alkyd resins to fix on a sheet, however, such anchoring takes time about 120 300 seconds
Предлагаемый сиособ получени циклокаучука от,- ичаетс от известного тем, что к фенолу добавл ют небольшое количество эфира двухосновной кислоты. Краски, изготовленные на циклокаучуке, иолучснном по предлагаемому способу, закре1к:1 ютс на меловаино бумаге в течение 10-60 сек.The proposed method for the preparation of a cyclo-rubber from, is derived from the well-known fact that a small amount of a dibasic acid ester is added to the phenol. The paints made on the cyclocoupler, which was observed according to the proposed method, were fixed: 1 on the chalk paper for 10-60 seconds.
Пример. В реактор загружают 145 вес. ч. безводного фенола; 7,5 вес. ч. дибутилового эфира фталевой кислоты или дибутилового эфира себациновой кислоты: 7,5 вес. ч. и тиокиси фосфора и 100 вес. ч. мелко нарезанного каучука (светлый крен непластифицированный). Смесь выдерживают при температуре 60--80 в течение 2-5 час. Затем темиературу повышают до 180, и смесь выдерживают еш,е 2 час. После это1о включают мешалку, и процесс ведут при посто нном перемешивании в течение 6 час. Реактор охлаждаю до температуры 120-125, и смесь раствор ют в 450 объемных част х уайт-спирита. Полученные в резуль-, тате побочных реакций смолы и часть фенола удал ют отстаиванием раствора промывкой его дистиллированной водой и водным фенолом. Циклокаучук высаживают спиртом и высушивают в ваку -cylIiи.чьнo I шкафу при температуре НО-120°.Example. Charged to the reactor 145 weight. anhydrous phenol; 7.5 wt. including dibutyl ester of phthalic acid or dibutyl ester of sebacic acid: 7.5 wt. including phosphorus and thioxides and 100 wt. h. finely chopped rubber (light roll unplasticized). The mixture is maintained at a temperature of 60--80 for 2-5 hours. Then tem perature is increased to 180, and the mixture is kept at an esh of 2 hours. After this, the stirrer is turned on, and the process is carried out with constant stirring for 6 hours. The reactor is cooled to a temperature of 120-125, and the mixture is dissolved in 450 volume parts of white spirit. The resins and part of the phenol obtained as a result of the side reaction are removed by settling the solution by washing it with distilled water and aqueous phenol. The cyclo-rubber is planted with alcohol and dried in a vacuum-cylIi.chno I cabinet at a temperature of НО-120 °.
Краска, изготовленна на основе полученного циклокаучука, по рецепту в вес. ч.:Paint made on the basis of the obtained cyclo-rubber, according to the recipe in weight. including:
