The preparation of enhancing inner lining material:
In addition to reinforcing agent, by table 1 proportioning, each raw material strengthening liner is added high-speed mixer and mixing uniform；By said mixture material Sending in double screw extruder, wherein reinforcing agent feeds system addition by first row pore or side, melt extrudes pelletize, obtains increasing Strong liner.Wherein, described mixing temperature is 20-50 DEG C, and rotating speed is 100-800 rev/min, and incorporation time is 2-5 minute；Described Each section of temperature of double screw extruder is 200-240 DEG C, and the draw ratio of double screw extruder is 36-48, and screw speed is 300-500 Rev/min.
Inner lining material is strengthened in the convection oven of 90 DEG C after dry 4 hours, with the sky injection moulding of sea, Ningbo by obtain Machine BS650-III sample preparation, injection temperature is set as 230-240-240-250 DEG C, and gained strengthens the physical property measurement result of inner lining material Performance is shown in Table 1.
Hot strength is tested by ISO 527 standard, and sample is I type sample, and test equipment is Zwick company of Germany Cupping machine Z020.
Bending strength is tested by ISO 178 standard, and specimen size is 4mm × 10mm × 80mm, and test equipment is moral The Apparatus for Bending at low-temp Z005 of Zwick Roell company of state.
IZOD notch impact strength is tested according to ISO 180 standard, and specimen size is 4mm × 10mm × 80mm, lacks The mouth degree of depth is 2mm.Test equipment is the shock machine HIT5.5P of Zwick Roell company of Germany.
Density is tested by ISO 1183 standard, and test equipment is the digital display fluid density meter of Japan ALFA MIRAGE MD-300S。
Cohesive force is tested: the existing batten that polyvinyl chloride resin is molded into 2mm × 10mm × 100mm, PVC batten is put the most again Put quadric injection mould in the mould of 4mm × 10mm × 100mm and strengthen inner lining material, obtain PVC profile and strengthen inner lining material Adherend, as shown in Figure 1.The size of cohesive force tested by cupping machine finally by Zwick company, thus characterizes enhancing Liner and the adhesive property of PVC profile.
Table 1 strengthens liner each component proportion (weight portion) transitivity
Continued 1:
As can be seen from Table 1 in the case of same glass fiber content, the inner lining material that strengthens of the present invention has more excellent mechanics Performance, especially rigidity are more better than enhancing PBT material, becoming apparent from the advantage in terms of moulding for steel.Secondly, phase is being provided Under conditions of rigidity, the enhancing inner lining material density of the present invention is lower, and prepared self-reinforcing co-extrusion section bar weight is lighter, symbol Close the lightweight that country advocates, low-carbon environment-friendly trend.
The preparation of self-reinforcing profile shapes:
Using main frame and the subsidiary engine of this main frame vertical design to carry out co-extrusion standby, by table 2 proportioning, main frame is used for extruding PVC profile, Subsidiary engine is used for extruding enhancing inner lining material, and main frame, subsidiary engine are extruded simultaneously, and after molding, cooling and shaping obtains self-reinforcing profile shapes；
Wherein, described main frame 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 rod Rotating speed is 18-22rpm；Described subsidiary engine 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 speed is 18-22rpm.
Each component proportion of table 2 self-reinforcing profile shapes and results of property (weight portion)
From the data of table 2 it can be seen that the cohesive force strengthening PBT material and PVC profile only has about 140N, and use the present invention Enhancing liner, its cohesive force with PVC profile brings up to 400-600N, is strengthen PBT material 3 times, and this illustrates the present invention Enhancing liner and PVC profile there is the more preferable compatibility, in the transport of section bar, during installing and using, do not have stripping Phenomenon.Secondly, enhancing PBT material just can plastify steady extruding the temperature range of 220-250 DEG C, and process window is narrow and processes Temperature is high, and the enhancing liner of the present invention wider at 160-215 DEG C within the scope of plastify all fine, and can with steady extruding, The enhancing liner of this explanation present invention has broader process window, and the extrusion molding temperature of 160 DEG C differs nothing with PVC profile Several, from root, avoid high temperature co-extrusion cause reducing foaming of PVC profile, carbonization variable color, the problems such as abnormal smells from the patient is big, the most relatively low Forming temperature also can be substantially reduced energy consumption, more environmentally-friendly.
