Abstract

The composite plastic sheet includes facing layer, middle layer and base layer, the facing layer is made of PVC, modified PP or modified PE; the middle layer is made of PVA film or polyurethane thermosol film; and the base layer is made of foamed PVC, modified PP or modified PE. Over the facing layer, there is one layer of coated dulling agent with pressed pattern. The composite plastic sheet has good comprehensive performance and its adhering middle layer combines the facing layer and the base layer well. The composite plastic sheet has the advantages of excellent heat insulating and sound isolating performance, high shock resistance, high anticorrosive performance, high electric insulating performance, high strength, beautiful appearance and easy cleaning.

Description

Technical field [0001] The invention relates to a plastic composite sheet, in particular to a flexible plastic composite sheet suitable for interior decoration of vehicles, ships, buildings, etc. and a manufacturing method thereof. Background technique [0002] At present, plastic products are widely used in the interior decoration of vehicles, ships, buildings, etc., but there is a shortcoming that it is difficult to meet both ideal surface performance and performance requirements such as thermal insulation and sound insulation. The force can satisfy the plastic products with beautiful appearance and high mechanical strength, but its thermal insulation and sound insulation properties are not ideal; while foamed plastics have excellent thermal insulation and sound insulation properties, but they do not have ideal appearance and surface mechanical properties. Therefore, its use is subject to certain restrictions. Like the interior decoration of the current vehicle door panels...
