    专利说明:

    The invention relates to the synthesis of foam and polyurethane based on compositions containing an agent that facilitates the taking of articles from molds and can be used in various industries.
    The aim of the invention is to impart a separation stability to the composition.
    As an internal release agent, it can be used in either solid or liquid form, which is dissolved, dispersed or suspended in one or several organosilicon surfactants, and as a polyhydric alcohol - a propoxy product. and the ethoxylation of diethylenegly. count (70%), glycerol (30%), having 2.0% 1
    ethylene oxide groups. + b

    - Polysiloxane I, representing cons. | internal polysiloxane-polyether-based copolymer-based release agent for L-based forms with functional hydroxy groups of approximate formula: Јe} (CH3) (CH3) (CH3) h
    SNBO (CH2CH CH3) OH9NO51 (CH3) s mol. with a mass of about 6000, an equivalent mass of hydroxide (d) 2000, (e) is 13%, (f) -35%, viscosity - 160 cSt;
    - Polysiloxane II, which is an internal release agent from the forms based on a copolymer of a thioether with a functional hydroxy group

    with an equivalent mass of hydroxyl (d) 2750, resin, mass 5500, value (e) 4.7% (1) 37%.
    The resulting mixture was kept at room temperature and taken to control at certain intervals of time.
    The results are presented in table. one,
    Examples 1-6. Surfactants A, B and C are prepared together with a polyhydric alcohol and a siloxane I as masterbatch compositions suitable for dilution with the same polyhydric alcohol for subsequent use. The stability of the masterbatches at room temperature is determined.
    The results are presented in table. 2
    Examples 7-13. Polyatomic-based working compositions are prepared using the same ranges of components with lower limits for the content of siloxane and surfactants and the resistance is determined in a similar way.
