Table 1 strengthens liner each group distribution ratio (parts by weight) transitivity
Continued 1：
As can be seen from Table 1 in the case of same glass fiber content, enhancing inner lining material of the invention has more excellent
Mechanical property, especially rigidity are more better than enhancing PBT material, more obvious to mould advantage in terms of Dai Gang.Secondly, carrying
For it is identical it is rigid under the conditions of, enhancing inner lining material density of the invention is lower, and prepared self-reinforcing co-extrusion section bar weight is more
Gently, the lightweight of country's promotion, low-carbon environment-friendly trend are met.
The preparation of self-reinforcing profile shapes：
It is standby using main frame and the subsidiary engine of main frame vertical design progress co-extrusion, matched by table 2, main frame is used to extrude PVC
Section bar, subsidiary engine are used to extrude enhancing inner lining material, and main frame, subsidiary engine are extruded simultaneously, and cooling and shaping obtains self-reinforcing abnormal shape after shaping
Material；
Wherein, the main frame is double screw extruder, and head temperature is 175-195 DEG C, and the area's temperature of fuselage one is 155-165
DEG C, the area's temperature of fuselage two is 165-175 DEG C, and the area's temperature of fuselage three is 175-185 DEG C, and the area's temperature of fuselage four is 175-185 DEG C, spiral shell
Bar rotating speed is 18-22rpm；The subsidiary engine is single screw extrusion machine, and head temperature is 175-195 DEG C, and the area's temperature of fuselage one is
160-165 DEG C, the area's temperature of fuselage two is 160-175 DEG C, and the area's temperature of fuselage three is 175-185 DEG C, and the area's temperature of fuselage four is 175-
185 DEG C, screw speed 18-22rpm.
The each group distribution ratio and results of property (parts by weight) of the self-reinforcing profile shapes of table 2
The cohesive force that can be seen that enhancing PBT material and PVC profile from the data of table 2 only has 140N or so, and uses this
The enhancing liner of invention, the cohesive force of itself and PVC profile bring up to 400-600N, are strengthen PBT material 3 times, this explanation this
The enhancing liner of invention has more preferable compatibility with PVC profile, is not in during the transport of section bar, installation and use
Peeling.Secondly, enhancing PBT material can just plastify steady extruding in 220-250 DEG C of temperature range, process window it is narrow and
Processing temperature is high, and the enhancing liner of the present invention it is wider at 160-215 DEG C within the scope of plastify all very well, and can stablize and squeeze
Go out, the enhancing liner of this explanation present invention has broader process window, and 160 DEG C of extrusion molding temperature and PVC profile phase
The problems such as difference is very few, and high temperature co-extrusion is avoided from root and causes reducing foaming for PVC profile, and carbonization changes colour, and smell is big, simultaneously
Relatively low forming temperature can also substantially reduce energy consumption, more environmentally-friendly.
