Description
Изобретение относитс к способам получени защитно-декоративных покрытий на строительных издели х, преимущественно на асбестоцементе, и может быть использовано в промышленности строительных материалов.The invention relates to methods for producing protective and decorative coatings on building products, primarily asbestos cement, and can be used in the building materials industry.
Цель изобретени - повышение адгезии покрыти к основанию.The purpose of the invention is to increase the adhesion of the coating to the substrate.
Пример I. Прессованные ас- бестоцементные листы влажностью 2,5% нагревают до 80 с и нанос т на них распылителем окрашивающую композицию на основе жидкого стекла. Далее покрыти подвергают инфракрасному облучению в течение 5 мин, после чего их нагревают до 250°С. со скоростью 5°С/мин.Example I. Pressed asbestos cement sheets with a moisture content of 2.5% are heated to 80 s and a painting composition based on water glass is sprayed onto them. The coatings are then subjected to infrared irradiation for 5 minutes, after which they are heated to 250 ° C. at a rate of 5 ° C / min.
П р и м е р 2. Прессованные асбес- тоцементные листм влажностью 1,5% нагревают до 70 с и нанос т распыпи- телем на них окрашивающую композицию на основе жидкого стекла. Далее покрыти подвергают инфракрасному облучению в течение 4 мин, после чего их нагревают до 200°С со скоростью 6°С/мин.PRI mme R 2. Pressed asbestos cement sheets with a moisture content of 1.5% are heated up to 70 s and a painting composition based on liquid glass is applied by spraying onto them. The coatings are then subjected to infrared irradiation for 4 minutes, after which they are heated to 200 ° C at a rate of 6 ° C / min.
Приме р 3. Прессованные асбес- тоцементные листы влажностью 1% нагревают до и нанос т распылителем на них окрашивающую композицию на основе жидкого стекла. Далее пок- рыти подвергают инфракрасному облучению в течение 3 мин, после чего их нагревают до 170 С со скоростью 8 С/мин.Example 3. Pressed asbestos cement sheets with a moisture content of 1% are heated before and sprayed onto them with a painting composition based on water glass. Next, the coatings are subjected to infrared irradiation for 3 minutes, after which they are heated to 170 C at a rate of 8 C / min.
Примера (известный). Асбес- тоцементные листы нагревают до 60 С,Examples (known). Asbestos cement sheets are heated to 60 ° C.

По окончании процесса otBepmAe- , ни покрытий образцы охлаждают и подвергают испытани м, результаты которых представлены в таблице.At the end of the otBepmAe- or coating process, the samples are cooled and subjected to tests, the results of which are presented in the table.
Анализ данных таблицы свидетельствует о том, что предлагаемый способ отверждени силикатных покрытий позвол ет не только сократить в 2-5 раз длительность тепловой обработки покрытий , но и повысить адгезию покрыти к основанию на 70-80%, а также стойкость к истиранию на 10-20% по сравнению с известным решением.Analysis of the data in the table suggests that the proposed method of curing silicate coatings not only reduces the duration of heat treatment of coatings by 2-5 times, but also improves the adhesion of the coating to the base by 70-80%, as well as abrasion resistance by 10-20 % compared with the known solution.
