SYNTHETIC RESIN BOUNDARY STONE WITH EXCELLENT FLAME RETARDANCE AND IMPROVED BREAKING STRENGTH

摘要

The present invention relates to synthetic resin boundary stone with excellent flame retardance and improved breaking strength which has added glass fiber to improve strength of recycled polypropylene and an added flame retardant to improve flame retardance to provide excellent flame retardance and improve breaking strength to prevent a crack even when an impact is applied to improve durability. A plurality of support walls are formed in a longitudinal direction to divide a space formed inside an upper and a lower surface while a rear surface is opened. Side walls are formed on both side surfaces to block the side surfaces. A plurality of upper protrusions are formed on the upper surface at regular intervals. A lower holes is formed on lower surfaces of spaces divided by the support walls and penetrated by a mounting member buried in a concrete layer on a lower portion to be fixed. Pigments are added to realize various colors.;COPYRIGHT KIPO 2016
