(54) SSTU FOR STABILIZING POLYVINILE HIS IDA

one

The invention relates to the processing of polymers and relates to stabilizing compositions for polyvinyl chloride, used in compositions for the manufacture of artificial leather, film and other materials based on polyvinyl chloride (PVC).

A stabilizing composition for PVC is known, which includes the product of the interaction of stearic acid with metal oxides or hydroxides in butyl phthalate, but this composition is not characterized by sufficiently high physicomechanical properties of stabilized materials. ; The closest to the proposed set of features and the achieved effect is a composition for stabilizing polyvinyl chloride (SCS-I) containing a complex salt of carboxylic acids - the product of the interaction of oxides or metal hydroxides - barium, cadmium, zinc with carboxylic acids in the presence of additives, such as grease G23 In addition to the lubricant, for example, choline, as an additive, the composition contains dioctyl phthalate, epoxidized soybean oil, O1, and -methacryl- (bis-tri-nitne glycol) phthalate (MGF-9), diphenylolpropane at the following ratio Composition of the report, May. including:

However, this composition also has insufficiently high indices of the physical and mechanical properties of the material based on a stabilized composite.

The aim of the invention is to improve the physicomechanical properties of the material based on the stabilized composition. The goal is achieved by the fact that the composition for stabilizing polyvinyl chloride containing a complex salt of carboxylic acids and lubricant, as a complex salt of carboxylic acids, contains the product of the interaction of a mixture of oxides of cadmium, zinc, thorium, lead sludge of these oxides and barium hydroxide with ({carbonic acid acids С (.- Сл .. in the presence of calcium sun alkylbenzopsulfonic acid with the following ratio of components, m.ch .: Complex solution Calcium salt of alkylbenzenesulfonic acid 8.4-118.0 Lubricant9.8-44.8 Stabilizing compounds It may additionally contain 13.8-3380 parts by weight of a plasticizer and / or 31.6-79.7 parts by weight of an organophosphorus stabilizer. In addition, the composition may additionally contain other additives of a specific purpose, for example, epoxidized soybean oil, fillers , pore-forming agents, pigments, fungicides, etc. As carboxylic acids i, C-C .., L-FFA fractions containing carboxylic acids C g to C, e are used. A composition is obtained for stabilizing polyvinyl chloride by reacting a mixture of cadmium oxides, zinc, barium, lead or specified oxides and hydroxides with carboxylic acid fractions Cg-C at 60-13 ° C in the presence of the calcium salt of alkylbenzenesulfonic acid and additives for the intended purpose. Specific 1polymers with the proposed stabilizing compositions are given in table. 1. In table. Table 2 shows examples of the use of the proposed stabilization composition in polyvinyl chloride (PVC) compositions and shchmer measures using the known stabilizer SCS K-11 and its mixture with the calcium salt alkyl benzene sulfonic acid (ABSC). In tab. 3 shows the test results of plasticized PVC film compositions. When comparing the results of tests of plasticized PVC composites with the use of a known complex stabilizer (Shiimera 6-8) with the results of tests of similar compositions with the proposed stabilizing compositions (examples 1-5), it is clear that: in the proposed stabilizing compositions, one-electrode highly dispersed salts of carboxylic acids are present ; - introduction into plasticized PVC compositions of the proposed compositions increases the thermal stability of the compositions; - compositions according to the invention, containing also organic phosphites (examples 2 and 4) are more effective than compositions obtained by mechanical mixing of SCS, ABSK and organic phosphites (example 8); - increases the transparency of the films (results of light transmission), which improves the performance characteristics of materials, and expands the scope of their application. In tab. 4 shows the test results of rigid PVC film compositions. When comparing the results of tests of rigid PVC compositions using SCS K-11 with the results of tests of similar proposed compositions (Table 3), it can be seen that the use of the proposed compositions (Example 9) in low-plasticized compositions increases the thermal stability of the composition by 1.5–2 times , color fastness - 1.6 times. In tab. 5 shows the results of testing the compositions for the porous layer of IC. When comparing the results of tests of known polyvinyl chloride compositions, which contain the complex stabilizer SKS K-11 (example 19) with the results of tests of similar compositions (example 11) with the proposed composition, it is seen that the use of 15 formulations provided increases 1.3 times the thermal stability of the compositions; increase the heat resistance of the compositions. -4 times; improvement of the physical mechanical mechanics of the obtained materials by a stiffness coefficient after aging by 1.5 times, and by an aging factor by tensile strength by 1.5 times.
