One kind of impact-resistant insulation sheet bending method for its preparation

The present invention is in the field of insulation board, discloses an impact-resistant insulation sheet bending method of its preparation, said insulation sheet comprises a tungsten carbide, titanium nitride ball-milled, ball-milled alumina, glass wool, phenolic foam , polypropylene fibers, polyethylene dipentaerythritol pentaacrylate, bisphenol A epoxy resin of formaldehyde. The preparation method comprises the following steps: (1) were added to a ball mill tungsten carbide, titanium nitride, aluminum ball; (2) was added to the kettle temperature tungsten carbide, titanium nitride, alumina, glass wool, phenolic foam plastic, polypropylene fibers, polyethylene dipentaerythritol pentaacrylate, bisphenol a epoxy resin, formaldehyde, stirring the above ingredients; (3) and then molded sheet forming machine for bending impact resistant insulation sheet. Insulation sheet produced has low thermal conductivity, high flexural strength and impact strength characteristics.
