Description
Изобретение относитс к способу модификации лаков на основе гоолиалкиларилсилоксанов ..-.,.ч,:.е This invention relates to a method for modifying lacquers based on goolyalkylaryl siloxanes ..-., H,:. E
Известен способ модифика-ции лаков на основе полиалкиларилсило-ксанов BjBea.eHHeM в их ,состав полиорганОСидоксанов - продукта гидролиза алкилтрихлор.силанОВ, содержащих 6-12 aTOMOiB углерода в органическОМ радикале, Однако модифицирующа добавка не теплостойка,A known method of modifying lacquers based on polyalkylaryl-xanes BjBea.eHHeM in them, the composition of polyorganosidoxanes - a product of alkyltrichlorosilane hydrolysis, containing 6-12 aTOMOiB of carbon in the organic radical, However, the modifying agent is not heat resistant,
С целью .получени лаков с улучшенными физико-химическими свойствами, пригодных дл изготовлени теплозащитных покрытий, предлагаетс в качестве модифицирующейIn order to obtain varnishes with improved physicochemical properties suitable for the manufacture of thermal protective coatings, it is proposed as a modifying agent.

В аналогичных услови х получают пленки, солЧержащие 10-15% модифицирующей добавки. Результаты испытаний представлены в таблице .Example. In a lacquer based on a polymethylphenylsiloxane resin containing units of 25, the Patent lacquer is applied to steel substrates by dipping, soaked for 24 hours at room temperature and baked p: olean films for 1 hour at 200 ° C. Under similar conditions, films are obtainedSolventing 10-15% modifying additive. The test results are presented in the table.
Способ моди.фикации лаков на оонове полиалкиларилсилоксанов введением в их состав полиорганосилоксанов, отличающийс тем, что, с целью получени лаков с улучшенными физиКо-химичеоки.ми свойствами, пригодных дл изготовлени теплозащитных покрытий, используют полиметилсилоксаны общей формулы A method for modifying the varnishes on un-polyalkylarylsiloxanes by introducing polyorganosiloxanes into their composition, characterized in that polymethylsiloxanes of the general formula are used to obtain varnishes with improved physical and chemical properties suitable for the manufacture of heat-shielding coatings.
