Composite for road barrier

Abstract

The invention discloses a composite for a road barrier. The composite comprises the following raw materials: polypropylene resin, a modified antiaging agent, polyethylene resin, phthalic acid ester, o-hydroxybenzophenone, a silane coupling agent, diethyl aluminum hypophosphite and white carbon black. The modified antiaging agent is added and has good compatibility with the polypropylene resin andother raw materials; damage to a resin matrix due to ultraviolet rays can be effectively reduced; aging degradation caused by molecular chain breakage of the resin matrix is retarded; and aging resistance and mechanical properties of the composite are greatly improved.

Description

technical field

[0001] The invention relates to the field of material technology, in particular to a composite material for an isolation pier. Background technique

[0002] Polypropylene has good comprehensive mechanical properties, heat resistance, chemical resistance, insulation, molding performance and low density, and its cost is relatively low, so its application range is very wide. The application fields of polypropylene involve auto parts, electrical parts, chemical equipment, building materials, insulating materials, packaging materials, textile materials, fishing nets, daily necessities, etc. The application field of polypropylene is still expanding year by year, and the growth rate of its output has been ranking first among general-purpose plastics in recent years. However, the anti-aging performance of polypropylene needs to be further improved to meet the performance requirements of practical applications. Contents of the invention
