Abstract

The invention relates to the creation of plasticized compositions based on suspension polyvinyl chloride. The invention makes it possible to increase the melt flow rate by 4 to 11 times due to the fact that, as a lubricant, the composition contains, by weight, parts by weight. a mixture of glycerin or its derivatives, or a VAT residue of the distillation of fatty alcohols of the C ₂₀ -C ₂₈ 2-9 fraction

VAT residue of distillation of fatty acids of cottonseed oil 1 - 8. The composition also contains, by weight.h.

suspension polyvinyl chloride 100

ester plasticizer 40 - 60

lead silicate 1 - 4. 1 table.

The invention relates to the creation of plasticized compositions based on suspension polyvinyl chloride, which can be used to obtain film materials and artificial leathers.

The purpose of the invention is to increase the melt flow rate of the compositions.

Compositions according to the invention may contain the following components: polyvinyl chloride C-70; plasticizers: DAF-789 (orthophthalic acid ester and normal alcohols fraction); dioctyl phthalate (orthophthalic acid di-2-ethyl hexyl ester); tricresyl phosphate (orthophosphoric acid ester and a mixture of dicresol and tricresol); polyols: glycerin, methylglycerol, dimethylglycerol, polyglycerol — a distillation residue of glycerine distillation containing components with a degree of polycondensation of 2 to 4; VAT residue of the distillation of higher fatty alcohols - a mixture of fatty alcohols with an even number of carbon atoms; fraction VAT residue of the distillation of fatty acids of cotton oil production - waste oil and fat with acid number mg / g con 50- | 00; lead silicate.

The invention is illustrated by the following examples.

 fatty alcohols, 1 mac. The bottoms of the fatty acid distillation of cottonseed oil production are mixed in a laboratory blender at 90-100 ° C for 10 minutes and homogenized in a mixing drum for 30 minutes. The resulting mixture is used to determine the melt index on an IIRT-2 device with a load of 5 kg, then films of 0.4-0.5 mm thickness are rolled from it at 160it5 C for 10 minutes. Samples were prepared from rolled sheets to test the physicomechanical properties of the plastic compound. The tests were carried out according to GOST 16272-79.

The compositions according to the invention (examples 2-14), the known (example 15) and comparative (examples 16-27) methods are prepared analogously to example 1 and are presented in Tables 1 and 2.
