Изобретение относитс к произвол ству древесных плит и может быть использовано на действующих и стро щихс предпри ти х.The invention relates to the arbitrariness of wood boards and can be used in existing and under construction enterprises.
Целью изобретени вл етс повышение огнестойкости и физико-механических показателей плит.The aim of the invention is to improve the fire resistance and physical and mechanical properties of the plates.
Пример 1. Компоненты прессмассы берут в следук цем соотношении, мае. % (по сухому веществу): Алюмохромфосфатное св зующее14 Мочевина7 Фосфорна кислота 2 Древесное волокно 77 Древесное волокно обрабатывают водным раствором огнезащитного соетава , полученного путем растворени в воде мочевины и последующего добавлени в водный раствор мочевины алюмохромфосфатного св зующего и фосфорной кислоты при комнатной темпе .ратуре и перемешивании. Обработку древесного волокна провод т путем пневматического распьшени огнезащитного состава в барабанном смесителе или сушилке-смесителе. Полученную пресс-массу сутпат до влажности 4-6%,Example 1. Pressmass components are taken in the following ratio, May. % (by dry matter): Alumochromophosphate binder 14 Urea7 Phosphoric acid 2 Wood fiber 77 Wood fiber is treated with an aqueous solution of flame retardant soyote, obtained by dissolving urea in water and then adding a chromophosphate binder and a phosphoric content of the body of the body and a phosphoric content of the body, and a phosphoric content of the body, and a phosphoric content of the body of the body and the phosphoric acid in the urea water solution and then adding the phosphoric body and phosphoric acid to the body of the uric acid and the phosphoric content of the body of the body and the phosphoric acid in the urea water solution and then adding the body phosphoric acid and the phosphoric acid to the body and the phosphoric acid and the phosphoric acid in the urea water solution. stirring. The processing of wood fibers is carried out by pneumatic injection of flame retardant in a drum mixer or dryer-mixer. The resulting press mass surapat to a moisture content of 4-6%,
