В примере 20 в качестве матрицы древесных частиц состав содержит отход полистирола, имеющий предел текучести расплава 8 г/10 мин и температуру плавления 185°С.In example 20, as a matrix of wood particles, the composition contains polystyrene waste having a melt yield strength of 8 g / 10 min and a melting point of 185 ° C.
Соотношения компонентов для формирования поверхностного и внутреннего слоев теплоизоляционной панели, а также ее характеристики: твердость, предел прочности при изгибе и предел прочности при сжатии приведены в таблице 1.The ratios of the components for the formation of the surface and inner layers of the heat-insulating panel, as well as its characteristics: hardness, tensile strength in bending, and tensile strength in compression are given in table 1.
Как видно из примеров конкретного выполнения, заявляемый объект по сравнению с прототипом позволяет увеличить твердость, предел прочности на изгиб и предел прочности на сжатие изделия в среднем в 1,5 раза, а использование при формировании теплоизоляционной панели отходов древесины до 70 мас. % и вторичных термопластов позволяет значительно снизить ее себестоимость, к тому же повышается технологичность производственного процесса за счет формирования теплоизоляционной панели коэкструзией.As can be seen from examples of specific performance, the claimed object in comparison with the prototype allows you to increase hardness, ultimate flexural strength and compressive strength of the product by an average of 1.5 times, and the use of wood waste to form a heat-insulating panel up to 70 wt. % and secondary thermoplastics can significantly reduce its cost, moreover, the manufacturability of the production process is increased due to the formation of a heat-insulating panel by coextrusion.
