Abstract
The invention discloses a fluorocarbon resin synthesis process based on control of the drying time. The synthesis process includes the steps: (a) firstly, adding fluorine-containing olefin, olefin ester, olefin acid, olefin ether, an epoxy resin, a catalyst and an initiator into a reaction vessel according to a certain proportion; (b) adding a solvent into the reaction vessel, and stirring and mixing uniformly; (c) regulating the temperature and the pH value of the reaction system, and at a certain stirring speed, carrying out a reaction for a period of time; (d) distilling the reaction mixture under a certain pressure and temperature; and (e) cooling the distilled product, then drying for 20-30 min, grinding into a powder, and thus obtaining the target product. The fluorocarbon resin can be successfully synthesized, moreover, the synthesis efficiency is high, the synthesis cost is low, and the performance of the synthesized product is good; and moreover, by controlling the drying time in the reaction course, the reaction conversion rate and the product performance are improved.
Description
Technical field
The present invention relates to a kind of fluorocarbon resin synthesis technique based on controlling time of drying.
Background technology
?fluorocarbon resin is so that firmly C-F key is as skeleton, and with other resin-phase ratios, its thermotolerance, chemical-resistant, winter hardiness, low temperature flexibility, weathering resistance and electrical property etc. are all better, and due to its good crystallinity, therefore there is not adhesion, non-wettability.Be widely used in kitchen and mess kit, moulding mould, the senior coil coating of the industrial machines such as machinery slipper, food, weaving, papermaking, application and the lining aspect of various tank classes, line of pipes, pump class, reactor, interchanger and accurate apparatus etc.
Because fluorocarbon resin is all high-melting-point (180 ~ 380 ℃), be insoluble to the solid resin of solvent, thus the dispersing coating of water or solvent made, with mode applications such as spraying, electrostatic spraying, curtain coating, roller coat, or make powder coating, with electrostatic spraying or fluidized-bed dipping application.
In the technological process of synthetic fluorocarbon resin, will directly have influence on reaction conversion ratio and product performance time of drying, a suitable time of drying of how to confirm, the synthesis technique of fluorocarbon resin be seemed to particularly important.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of fluorocarbon resin synthesis technique based on controlling time of drying is provided, and this technique can successfully synthesize for fluorocarbon resin, and combined coefficient is high, synthetic cost is low, the good product performance synthesizing; And by controlling the time of drying in reaction process, thereby reaction conversion ratio and product performance are improved.
Object of the present invention is achieved through the following technical solutions: a kind of fluorocarbon resin synthesis technique based on controlling time of drying, comprises the following steps:
(a) first, according to a certain percentage Fluorine containing olefine, alkene ester, olefin(e) acid, alkene ether, epoxy resin, catalyzer and initiator are added in reactor;
(b) in reaction vessel, add solvent, be uniformly mixed;
(c) temperature and the pH value of adjusting reaction system, under certain stirring velocity, reaction for some time;
(d) reaction mixture is distilled at certain pressure and temperature;
(e) product distilling out is carried out cooling, then dry 20～30 minutes, grinds powder, obtained target product.
Describedly stir by three axle agitators.
Described solvent is alcohol ether.
Be 22 minutes described time of drying.
Be 28 minutes described time of drying.
Be 25 minutes described time of drying.
In sum, the invention has the beneficial effects as follows: can successfully synthesize for fluorocarbon resin, and combined coefficient is high, synthetic cost is low, the good product performance synthesizing; And by controlling the time of drying in reaction process, thereby reaction conversion ratio and product performance are improved.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited only to this.
Embodiment:
A kind of fluorocarbon resin synthesis technique based on controlling time of drying the present invention relates to, comprises the following steps:
(a) first, according to a certain percentage Fluorine containing olefine, alkene ester, olefin(e) acid, alkene ether, epoxy resin, catalyzer and initiator are added in reactor;
(b) in reaction vessel, add solvent, be uniformly mixed;
(c) temperature and the pH value of adjusting reaction system, under certain stirring velocity, reaction for some time;
(d) reaction mixture is distilled at certain pressure and temperature;
(e) product distilling out is carried out cooling, then dry 20～30 minutes, grinds powder, obtained target product.
Describedly stir by three axle agitators.
Described solvent is alcohol ether.
Be 22 minutes described time of drying.
Be 28 minutes described time of drying.
Be 25 minutes described time of drying.
In the technological process of synthetic fluorocarbon resin, will directly have influence on reaction conversion ratio and product performance time of drying, a suitable time of drying of how to confirm, the synthesis technique of fluorocarbon resin be seemed to particularly important.In order to obtain best time of drying, the present invention has done the impact experiment of different time of drying on reaction conversion ratio and product performance, result is known by experiment: different time of drying is very large on reaction conversion ratio and product performance impact, suitably increase time of drying, can improve reaction conversion ratio, but, in the time bringing up to certain value time of drying, increase again time of drying, not only can not improve reaction conversion ratio, also by reducing the performance of product, therefore after considering, be defined as 20～30 minutes time of drying of the present invention, and the best is 25 minutes.
The above, be only preferred embodiment of the present invention, not the present invention done to any pro forma restriction, every foundation technical spirit of the present invention, and any simple modification, equivalent variations that above embodiment is done, within all falling into protection scope of the present invention.
