    1. Plasticiser-containing foils formed from partially acetalised polyvinyl alcohols, characterised in that they contain as plasticiser mixtures of a) esters of organic, cyclic acids with alcohols of 4 to 10 carbon atoms and b) esters of glycols and aliphatic monobasic acids with 4 to 10 carbon atoms, in the ratio of 85:15 to 15:85% by weight.

    专利说明:

    The invention relates to plasticizers of plastic films, in particular to a composition for the plasticization of a polyvinyl butyral film used to make multi-layered 5-foot glass, and can be used in the chemical industry. A composition for plasticizing a polyvinyl butyral film containing an organic cyclic ester tj is known. The disadvantage of this composition is low moisture resistance of the film. The closest to the present invention is a composition for plasticizing a polyvinyl butyral film containing an ester of phthalic acid and an alcohol with a carbon number of 4-10 or a mixture of these alcohols and an additional ester of phosphoric acid-20 lots 2. A disadvantage of the known composition is that the strength of the plasticized polyvinyl butyral film is not fully satisfactory. The chain of the invention is to increase the strength of the plasticized film. The goal is achieved by the fact that the composition for the plasticization of polyvinylbutyral Shgenky acid containing phthalic acid ester and alcohol with a carbon number of 4-10 or a mixture of these alcohols and an additional ester, contains the tri- or tetraethylene glycol and aliphatic ether monobasic acid with the number of carbon atoms 6-8 in the following ratio of components, wt.%: Ether of tri- or tetraethylene glycol and aliphatic monobasic acid with the number of carbon atoms 6-814-50 Phthalic ester Else Preposition The composition is prepared by simple mixing of the individual components. Example 1. Polyvinyl butyral resin available in commerce with a hydroxyl content of 20.7 wt.% (Calculated as vinyl alcohol) is mixed on a roller machine with a different amount of composition containing triethylene glycol di-2-ethyl butyrate (3 EG) and mixed ester (C 6 / 10) phthalic acid and mixtures of alcohols with 6,8,10 carbon atoms.

Example 1 is repeated with the difference that the formulation containing diethylene compound triethyleneglyl (3G 7) and complex heptyl ir phthalic acid (C7) are used. The strength of plasticized Yenko is given in table. 2. Example 3. Example 1 is repeated. The difference is that they use a coconut containing triethylene glycol dihydrogenate (SG 7) and butyl phthalate (C 4). The strength of plasticized film is given in Table. 3. Example 4. Example 1 is repeated. The difference is that 28% of a film of a composition of 50% by weight of triethylene glycol dihepoate (3G 7) and% by weight indicated in Table 2 is used. 4 complex phthalic acid ester.

    Example 7. Samples of all plasticized films are used to make laminated glass. At the same time they are placed between two silicate glasses, each of which has a thickness of 3 mm, followed by the combination of glasses by heating to 130-150 C at a pressure of 12 bar. The adhesion strength between silicate glasses and plasticized polyvinyl butyral film is tested by the Pummel method. All test laminated glasses show the value (Pummel 10.
    Pummel value is determined by the following Table
