PLASTIC COMPOSITE PANEL AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a plastic composite panel used in a concrete construction site of construction work and civil engineering work, lightweight with excellent flexural rigidity, excellent surface smoothness of concrete after placing concrete and also excellent recyclability after use. SOLUTION: This plastic composite panel using plastic as a main material has a main layer 1 and an outer layer 2 formed on the surface of the main layer 1. The main layer 1 has pores, and the outer layer 2 comprises thermoplastic resin whose melt flow rate is in a range of 0.1-10 g/10 min.
