It is standby that employing main frame and the subsidiary engine of this main frame vertical design carry out co-extrusion, and by table 2 proportioning, main frame is used for extruding enhancing benzene second Thiazolinyl composition material, subsidiary engine is used for extruding thermoplastic resins section bar, and main frame, subsidiary engine are extruded simultaneously, and after molding, cooling and shaping obtains To self-reinforcing profile shapes；
Wherein, described main frame is single screw extrusion machine, and head temperature is 175-195 DEG C, and fuselage one district temperature is 160-165 DEG C, Fuselage two district temperature is 160-175 DEG C, and fuselage three district temperature is 175-185 DEG C, and fuselage four district temperature is 175-185 DEG C, screw rod Rotating speed is 18-22rpm；Described subsidiary engine is double screw extruder, and head temperature is 175-195 DEG C, and fuselage one district temperature is 155-165 DEG C, fuselage two district temperature is 165-175 DEG C, and fuselage three district temperature is 175-185 DEG C, and fuselage four district temperature is 175- 185 DEG C, screw speed is 18-22rpm.
Each component proportion of table 2 self-reinforcing profile shapes and results of property (weight portion)
As can be seen from Table 2, the present invention utilizes thermoplastic resin section bar as cortex, and its glossiness reaches more than 90 °, and relatively aluminum closes The glossiness (about 70 °) of gold is significantly improved, it is possible to provide excellent appearance, high rigidity reinforced styryl compositions material Material is as sandwich layer, and the serviceabilities such as it can provide the intensity required for bound edge material, rigidity, the two co-extrusion prepares in addition The thermal conductivity of self-reinforcing profile shapes is the thermal conductivity (about 200 W/mK) of 0.20-0.30 W/mK, substantially less than aluminium alloy, because of This, the self-reinforcing section bar of the present invention has lower thermal conductivity, and at insulation, appearance aspect more has advantage.This The profile shapes of invention preparation can replace aluminum alloy edge-wrapped material, before desk, cabinet, wardrobe bound edge etc. have preferably application Scape.
