Title:
SELF-REINFORCED PROFILE AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/215576
Kind Code:
A1
Abstract:
A self-reinforced profile, a preparation method therefor and an application thereof. The self-reinforced profile comprises a PVC profile and a reinforcing lining material provided within the PVC profile cavity, the weight portions thereof are as follows: 100 parts of the PVC profile; 5 to 120 parts of the reinforcing lining material, the reinforced lining material comprising by weight 25 to 65 parts of a styrene-based copolymer; 20 to 40 parts of a reinforcing agent A; and 10 to 25 parts of a reinforcing agent B. The method for preparing the self-reinforced profile includes first preparing the reinforcing lining material, and then co-extruding by using a main machine and an auxiliary machine which is configured to be perpendicular to the main machine, the main machine being used for extruding the PVC profile, and the auxiliary machine being used for extruding the reinforcing lining material; the main machine and the auxiliary machine extruding at the same time, molding and then shaping by cooling, so as to obtain the self-reinforced profile. The self-reinforced profile may prevent the reinforcing lining and profile from peeling off during transportation, installation and use, as well as prevent carbonization of the PVC profile caused by high temperature co-extrusion; the present invention has excellent electrical conductivity, and can greatly reduce the risks of high-rise buildings being struck by lightning in thunderstorms.
