Abstract

The invention relates to a novel polyvinyl chloride (PVC)+ medium composite (polypropylene) PP foamed sheet material. The upper part of a multi-layer composite sheet material is provided with an upper press polishing wheel, and the lower part of the multi-layer composite sheet material is provided with a lower press polishing wheel; a substrate plate and a substrate-plate rolling wheel are arranged at entering ends of the upper press polishing wheel and the lower press polishing wheel; a two-side ultrasonic surface roughening device is arranged at a position for passing through the substrate plate; ultrasonic surface roughening pretreatment of the two sides of the substrate plate is carried out, and then the substrate plate passes through extinction ABS extruded by an extinction ABS extruder and PP foaming material extruded by a PP foaming extruder, and is extruded for molding, by the upper press polishing wheel and the lower press polishing wheel, to obtain the multi-layer composite sheet material. The ultrasonic surface roughening device is added for surface roughening before the substrate plate enters, so that the multi-layer composite sheet material is more resistant to mechanical impact, high temperature and low temperature, and no layer rising phenomenon may occur.

Description

technical field [0001] The invention is a novel PVC+medium composite PP foam board, which belongs to the technical field of machinery. Background technique [0002] The current production of multi-layer composite boards is not processed by ultrasonic surface roughening, which is easy to delaminate and has poor mechanical impact resistance, high temperature and low temperature resistance. Contents of the invention [0003] The purpose of the present invention is to provide a new type of PVC+medium composite PP foam board. By adding ultrasonic surface roughening pre-treatment to both sides of the substrate, the multi-layer composite board is more resistant to mechanical impact, high temperature and low temperature, and not The purpose of layering will appear. [0004] Its purpose is to achieve this, in figure 1 Among them, a new type of PVC+medium composite PP foam board is composed of a substrate roll, a substrate, a double-sided ultrasonic surface rougher, a matting ABS ...
