ENVIRONMENTALLY-FRIENDLY SALT PONT COMPOSITE FLOOR SHEET

摘要

According to the present invention, produced is a salt pond floor sheet comprising: a bottom layer which may be a conventional salt pond floor sheet including polyvinyl chloride; an intermediate filler cut on the bottom layer with a uniform size of 1-5 centimeters; and a top layer made of a material including C-PET. According to the present invention, a role of an intermediate layer filler is ensured to include a role of increasing a coefficient of friction of an intermediate layer with the top layer and the bottom layer and a role of absorbing foreign materials. As the intermediate layer filer, dry grass including dry straw of 1-5 centimeters is used, and the top layer is produced by using a material including C-PET. The thickness of the top layer should not be over 5 centimeters, and an intermediate material should have a uniform size of 1-5 centimeters and a thickness which is not over 5 centimeters. According to the present invention, the thicknesses of the top layer and the intermediate layer have been studied to have values which can minimize damage with respect to durability and heat resistance. In particular, the intermediate material made of dry grass including straw is used to remedy spalling and tearing of the top layer, to ensure durability and inner skin stability of the top layer, and to absorb contaminants.;COPYRIGHT KIPO 2017
