METHOD OF RUBBER-POLYMER PLATES PRODUCTION Russian patent published in 2008 - IPC B29C35/02 B29D7/00 C08J3/24 

FIELD: technological processes.

SUBSTANCE: rubber-polymer plates are designed for lining of different surfaces and structures exposed to permanent load and wear. Layer of uncured rubber 1.5÷20.0 mm thick is placed in mould with regulated shear deformation, above which layer of ultrahigh molecular polyethylene is evenly filled with molecular mass of 1.5·10⁶ g/mole ÷ 10.0·10⁶ g/mole. Volume of ultrahigh molecular polyethylene layer filling is calculated on the basis of final height of compact polyethylene layer, selected from 1.5 to 20.0 mm, cross section of mould and density of ultrahigh molecular polyethylene of 0.936 g/cm³. Then prepared composite is exposed to volumetrical compression in mould and then sintered at the temperature of 160÷210°C, pressure of 30 kg/cm², and cure for 15 minutes - 1.5 hour.

EFFECT: preset thickness of plates and high strength of connection between layers.
