Description
The present invention is the technical field that is used for carrying out Chemical Preservation and sealing.
As everyone knows, fluoroplastics are best a kind of plastics of chemical stability in the engineering plastics, but its surface energy is very low, with the crosslinked poor ability of different molecule, are typical difficult sticking materials.
At present, all be the adhering method that adopts modification to handle both at home and abroad, for example: dark liquid of the sodium bitter edible plant and sodium bitter edible plant tetrahydrofuran solution wet processed method; Plasma processing method; High frequency discharge splash facture etc.; after these methods are handled; the surperficial deepening or the blackening of plastics; dielectric properties descend under hot environment; not UV resistant irradiation; can not under atmospheric condition, expose for a long time, and treatment facility costliness, complex process, treating processes mostly need be carried out under protection of inert gas such as nitrogen or argon gas.Treatment solution has very strong corrodibility, have in addition fiery fried danger is arranged, and the heat-resisting and resistance to chemical corrosion of binding agent mates with fluoroplastics are very difficult, so bonding strength is not high.
Domesticly once silicone pressure-sensitive adhesive was used to need not to carry out the bonding of fluoroplastics that modification handles, but bonding strength has only 20kg/cm
2, envrionment temperature is no more than 80 ℃, and the bond area maximum is no more than 400cm
2
Because the bonding difficulty of fluoroplastics, most at present way that adopts pine lining flange is about to fluoroplastics and is lined directly in the metal vessel, and the dependence flange fixes, and this method is under negative pressure 700-760mmHg situation, and the fluoroplastics distortion can't be used.
The purpose of this invention is to provide a kind of adhering method, and binding agent performance and fluoroplastics are complementary without surface modification treatment, the bonding strength height, technology is simple, adhering method that expense is low and binding agent.
The adhesive method of fluoroplastics and metal: be that the metallic surface is removed degreasing, hacking earlier, then at 0.5～2kg/cm
2Pressure under, the thick adhesive special of the present invention of spraying last layer 0.1～0.2mm, and binding agent is solidified under 320～370 ℃ temperature, clean fluoroplastics be will clean again and the metal that is sprayed with binding agent or the surface of metal vessel will be pasted on, carry out the sintering curing second time, this time the solidified temperature is 320～370 ℃, and pressure is 0.5～2kg/cm
2, also can add quartz sand and be filled in the container and be cured, cooling at last gets final product.
Binding agent of the present invention is to be cooperated to stir by following chemical substance to form.
1, tetrafluoroethylene 15-35%
2, R 1216 20-40%
3, polyphenylene sulfide (PPS) 15-35%
4, chromium sesquioxide 0.1-1%
5, titanium dioxide 0.1-2%
6, all the other are water
To chromium sesquioxide and titanium dioxide, can use any one separately, or two kinds mix to be used, can two kinds do not use yet.
The basic recipe of this binding agent not only can be used for the bonding of fluoroplastics and metal, and can be used for the bonding of metal and metal.
Bonding between metal and the metal, its method is identical with the adhering method of fluoroplastics and metal, as long as the proportioning of binding agent is done following adjustment.
1, tetrafluoroethylene 5-10%
2, R 1216 5-10%
3, polyphenylene sulfide (PPS) 40-60%
4, all the other are water
Use caking agent of the present invention, after metal and fluoroplastics bonding, test its bonding strength and can reach 1428N/cm
2, not only can satisfy the service requirements under the normal pressure, and can under negative pressure, use.
Advantage of the present invention: adhering method is simple, and bonding strength is big, and expense is low, and adhesiveproperties and fluoroplastics are complementary, can be bonding firm without surface modification treatment, and can carry out the bonding of large-scale workpiece.
This binding agent does not fire, not quick-fried, nontoxic, anti-air aging, the energy long-term storage, corrosion resistance nature, be only second to fluoroplastics, and being better than stainless steel and anti-corrosion enamel, it is insoluble to the various known solvent below 180 ℃, can anti-various organic acids below 200 ℃ and the concentrated sodium hydroxide of boiling shape, 24 hours no changes in the chloroazotic acid at normal temperatures, and have the resistance toheat that under 150 ℃ of high temperature, keeps higher mechanical strength, and all can be bonding to various metals and the plastics of ability more than 320 ℃, all raw material all is based on domestic resource fully.
Embodiment: the carbon steel polymerization tower internal surface that the chemical plant is used cleans up, and behind the sandblast hacking, this binding agent is sprayed to treat to add 1kg/cm on the agglutinating surface
2Slight pressure, send in 350 ℃ the electric furnace, solidified through 20 minutes, again clean fluoroplastics are affixed on the metallic surface that is sprayed with binding agent, the quartz sand of portion's filling is within it sent in 350 ℃ the electric furnace again and is carried out regelate, takes out cooling then, bonding can finishing, bonding strength reaches 1000N/cm
2More than.
