    This invention relates to the stabilization of polymers, in particular to a composition for the stabilization of polyvinyl chloride (PVC).
    A known composition for the stabilization of PVC, including dibutylovodilaurat, epoxidized soybean oil and a compound of the formula RCONHNHCOOII, where Ralkyl C. Q, cycloalkyl, aryl, alkynyl, arylalkyl, alkoxy group C. g aryloxy or aryl l.
    The disadvantage of this composition is an insufficient stabilizing effect. Thus, a color change of PVC at 180 ° C occurs within 70 minutes.
    The closest to the invention in its technical essence is a composition for stabilizing PVC, containing, by weight, polyol ester and saturated fatty acid — pentaerythritol stearate 100; Calcium stearate and zinc salt of a saturated fatty acid - zinc stearate 200350; the lubricant is paraffin 200-300 and stearic acid 40, and the antioxidant is diphenylolpropane 5-20 (J2.
    This composition also has insufficient stabilizing effect. The film obtained from the composition containing per 100 weight.h. PVC 3.35-7.6 weight.h. this composition has a thermal stability at 180 ° C 55-85 minutes
    The aim of the invention is to increase the stabilizing effect.
    This goal is achieved in that the composition for stabilizing polyvinyl chloride, including calcium stearate, zinc salt of a saturated fatty acid, ester of a polyol and saturated fatty acid and lubricant, contains zinc stearate or octoate as a zinc salt-saturated fatty acid. polyol and saturated fatty acid - pentaerythritol stearate or glycerin di12-hydroxystearate or trimethylolpropanlaaurate, as a lubricant paraffin or ester. adipic acid - pentaerythritol stearic acid It also contains sodium aluminosilicate of the formula (0.900, 99). (1, 83-2, 04) SiO with bound water content (20.921, 6% wt.%) And 2-ethylhexylthioglycolt, or dodecanediol-1,10-bistioglycolt, or H-octadecylthioglycollate in the following ratio of components, May .ch .:

    The composition additionally contains 40-100 weight.h. epoxidized soy oil in the amount of 40-100 wt.h.
    The composition additionally contains oC-phenylindol in an amount of 3 m.ch. The degree of stabilization is determined by determining the static thermal stability of the rolled web. For this purpose, the 4th cloths containing the stabilizing composition are molded into a molded mass of PVC on a rolling mill 5 with a size of 450,220 mm (firms
    Burstoff) at 170 ° C and the number of revolutions of the rolls of 12.5 rpm for 5 min. About 0 mm thick, the blades are cut into square samples of length
    10 mm edges, which are then fed to a drying cabinet with six rotating grates (Heraeus FT 420 R) at 180 ° C. Every 15 minutes, a sample is taken and a color change is determined. At the same time, the experiment was stopped after: a significant deterioration in the initial color of the sample.
    Example 1 (general recipe). In a vessel with a capacity of 15 l solution
    aluminate is mixed with strong
    mixing with silicate solution. Stir with a dispersing disc at 300 rpm. Both solutions are room temperature. With an exothermic reaction
    as the primary precipitation product, x-ray amorphous sodium aluminosilicate is formed. After 10 minutes of slow mixing
    the suspension of the precipitated product is transferred to a vessel for co-crystalline, / where it is settled for 6 hours at 90 ° C with stirring (250 rpm) for the purpose of crystallization. After sucking off the liquor from the crystalline porridge and further washing with deionized water, until the waste wash water has a pH of 10, the filter residue is dried. The water content is determined by heating the preheated products to 8000 ° C for one hour. Washed to pH 10 or neutralized and then dried sodium aluminosilicates are then ground in a ball mill. Coarseness
    the grains are determined by sedimentation weights.
