Abstract

Inventia se refera la un antistatizant pentru policlorura de vinil care, în scopul largirii gamei sortimentale si asigurarii unui efect permanent de antistatizare, dispune de o structura si o compozitie chimica de sita moleculara de tip zeolit 4A, fiind utilizabil în orice forma cationica, preferabil în forma de sodiu si care se introduce în masa de polimer în proportie de 15...20% în stare de pulbere microcristalina, fie divizata si cu umiditate maxima de 1% si se obtine pe cale hidrotermala din silicat de sodiu, oxid de aluminiu, hidroxid de sodiu si apa la 60...100 degree C sub agitare, urmata de cristalizare în regim stationar timp de 5,5...6 h la 100 + - 2 degree C, spalare cu apa de condens sau demineralizata pentru ajustarea pH-ului, la valori cuprinse între 9,5...1,5, aducerea masei cristaline în stare de pulbere prin uscare în etuva la 110 degree C sau sub forma de suspensie apoasa cu 10...12% aluminosilicat alcalin care se usuca prin atomizare la temperaturi de 430...450 degree C pe intrare si 180...200 degree C pe iesire gaze.The invention relates to a vinyl polychloride antistatic agent which, in order to increase the assortment range and provide a permanent antistatic effect, has a chemical structure and composition of molecular zeolite 4A type sieve, being usable in any cationic form, preferably in sodium form and which is introduced into the polymer mass in a proportion of 15-20% in the state of microcrystalline powder, either divided and with a maximum humidity of 1%, and is hydrothermal obtained from sodium silicate, aluminum oxide, sodium hydroxide and water at 60 to 100 ° C with stirring followed by stationary crystallization for 5.5 ... 6 hours at 100 + - 2 ° C, washing with condensation or demineralized water for pH adjustment at values ranging from 9.5 to 1.5, bringing the crystalline mass in powder state by drying in the oven at 110 ° C or in the form of an aqueous suspension of 10-12% alkaline aluminosilicate which is dried by atomization at temperatures of 430 ° C. . 450 degree C on the inlet and 180 ... 200 degrees C on the gas outlet.
