Desired thermoplastic resin is a vibrin.Vibrin is favourable, and this is because it has 50-70 ℃ fusing point, and it does not need superheated and be easy to handle.
According to second aspect of the present invention, a kind of weatherstrip window glass of car or method of afterbody window glass of installing on car body is provided, and this method may further comprise the steps: coat binding agent (this binding agent by join 2-8% (weight) thermoplastic resin in the urethane base-material and be heated to 60 ℃ of-80 ℃ of formation) around glass or car body window-frame; Vacsorb glass also pressurizes to it facing to window-frame; Use the air cooling binding agent.
In the explanation embodiment, being used to cool off the temperature that the air of binding agent has is 20 ℃.By being blown into air, binding agent is forced to be cooled to 50 ℃ or lower at short notice, therefore shows interim glass hold facility.
Now only certain preferred technical scheme of the present invention is described particularly by the mode of embodiment and with reference to accompanying drawing, wherein:
Fig. 1 shows the skeleton view that windshield glass is installed on car body according to the present invention;
Fig. 2 is the sectional view that the line 2-2 along Fig. 1 is cut open;
Fig. 3 shows that binding agent of the present invention keeps the curve of performance temporarily;
Fig. 4 is the curve that shows binding agent tensile strength properties of the present invention; With
Fig. 5 A and Fig. 5 B show to use binding agent of the present invention how windshield glass to be installed in sketch on the car body.
Following description in fact only is demonstration, and does not mean that the restriction to the present invention or its application or purposes.
With reference to Fig. 1, vehicle 10 comprises and is installed in by right front post and left front post 12,14, top 16 and covers the previous section of the front windshield 20 of 18 opening parts that limit.
Refer now to Fig. 2, will be connected around the windshield glass 20 by on 16 the formed window-frame 22 in front of top by binding agent 24.
Referring now to Fig. 3, this figure shows that binding agent of the present invention keeps the curve of performance temporarily.In this curve, transverse axis represents to be added to the add-on (%) of the thermoplastic resin in the urethane, and Z-axis represents to keep performance or confining force (g/cm temporarily
2).
According to following method, measure windshield glass, promptly make glass remain on the interim performance that keeps of instantaneous acquisition of back bonding surface unit surface on the car body with the binding agent that is clipped between windshield glass and the car body by pressurization.
In curve, (real circle) expression observed value.Interim confining force is about 7g/cm when as seen, using urethane separately
2When urethane was used as base-material and adds 2% thermoplastic resin, its interim confining force that has was 22g/cm
2When the thermoplastic resin that adds 4% in the urethane base-material, final interim confining force is 42g/cm
2Equally, add 10% thermoplastic resin and produce 68g/cm
2Interim confining force.This means that interim confining force increases with the thermoplastic resin add-on with being directly proportional.
The actual now heavily about 1kg-17kg of windshield glass that uses.The side this windshield glass is attached on the car body, the bond area that needs is approximately 350cm
2, in order only to support windshield glass, consider the connection angle of windshield glass with binding agent, need interim confining force to be at least about 18g/cm
2In actual applications, for security consideration, wish that minimum interim confining force is 20g/cm
2As seeing in the curve,, can obtain 20g/cm by adding 2% or higher thermoplastic resin
2Interim confining force.
