Description
Предметом изобретени вл етс способ получени на основе высокополимерных веществ пористых материалов дл технических изделий, подошв и др.The subject of the invention is a method for producing porous materials for technical products, soles, etc., based on high polymer materials.
По предлагаемому способу образование пор при термообработке изделий происходит вс иедствие реакций конденсации, протекающих между вз тыми в смесь высокополимерами, что приводит к выделению газообразных продуктов, образующих поры, и к одновременной стабнлизации этих пор в результате образовани модифицированных соединений полимеров .According to the proposed method, the formation of pores during heat treatment of products occurs through condensation reactions between high polymers taken into a mixture, which leads to the release of gaseous products that form pores and the simultaneous stabilization of these pores as a result of the formation of modified polymer compounds.
Особенность способа заключаетс в том, что примен ют смесь полимеров , способных к реакции конденсации между их функциональными группами. В качестве высокополимеров примен ют, например, нитрильный каучук СКН-40 и капрон.A feature of the process is that a mixture of polymers capable of a condensation reaction between their functional groups is used. For example, nitrile rubber SKN-40 and caprone are used as high polymers.
Пример. Смесь из 100 вес. ч. каучука СКН-40 и 16 вес. ч. капрона в виде волокна (например, в виде отходов соответствующих производств ) вальцуют в течение 30 мин. при температуре вальцов 30-40°.Example. A mixture of 100 wt. including rubber SKN-40 and 16 wt. h. caprone in the form of fiber (for example, in the form of waste from the relevant production) roll over 30 minutes. at a temperature of rollers of 30-40 °.
Из вальцованного полупродукта вырезают заготовки технических изделий , например, подошвы, и закладывают их в прессформу дл термообработки в прессе, которую ведут в течепие 5-8 мин. при 260°.Billets of technical products, for example, soles, are cut out of the rolled intermediate product and placed in a mold for heat treatment in a press, which is carried out for 5-8 minutes. at 260 °.
Полученные издели характеризуютс следующими физнко-механическими данными; Объемный вес 0,3-0,6 с. /с.«-1 Сопротивленце разрыву 20-25 кг/см-. Сопротивление раздиру 18-20 кг/см. Сопротивление истиранию 300-400 . с.чThe resulting products are characterized by the following mechanical and mechanical data; Volume weight 0.3-0.6 s. / c. "The Resistance to Tear 20-25 kg / cm-. Tear resistance 18-20 kg / cm. Abrasion resistance 300-400. s.ch
