Title:
SELF-REINFORCING PROFILED BAR, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/215572
Kind Code:
A1
Abstract:
A self-reinforcing profiled bar, a preparation method therefor and an application thereof. The self-reinforcing profiled bar comprises, in parts by weight, 100 parts of PVC profile and 5-120 parts of reinforcing lining material provided in a cavity of the PVC profile. The reinforcing lining material comprises the following components in parts by weight: 25-65 parts of styrene-based copolymer and 30-65 parts of reinforcing agent. The preparation method therefor comprises: first preparing a reinforcing lining material; and then, performing co-extrusion by using a main machine and an auxiliary machine designed perpendicular to the main machine, the main machine being used for extruding a PVC profile, the auxiliary machine being used for extruding the reinforcing lining material, and the main machine and the auxiliary machine performing extrusion simultaneously; and cooling and shaping after molding to obtain a self-reinforcing profiled bar. The self-reinforcing profiled bar can avoid the peeling problem between a reinforcing lining and the profile during transportation, installation and use, and the carbonization problem of the PVC profile caused by high temperature co-extrusion, and therefore has good production stability and molding stability.
