Composite flooring tile reinforced with rice husk ash and hemp fiber.

Abstract

The invention describes a method for producing floor tiles from recycled high-density polymer matrices, involving the following steps: dry powdering of HDPE and PP forms, baking of rice husk ash and hemp fibers, blending of HDPE powder, PP powder, micro hemp fiber, ATH, and Maleic Anhydride Grafted Polymer, homogeneous spreading of the prepared dry composite mixture, raising the mold temperature to between 165°C and 175°C, compressing the mixture under hydraulic pressure to melt the polymer matrix by completely enveloping the fillers, and, without removing the press pressure, controlled cooling of the material at a rate of 5°C - 8°C per minute via water / oil circulation channels inside the mold to below 40°C, and finally, removing the tile body from the mold in its final form.
