The invention relates to fluoropolymer-based compositions used in the manufacture of orifice fluoropolymer products.
In the industry engaged in the production and use of fluoroelastomers and fluoropolymer-plastic materials, there is a need for polymeric materials, whose curing can be carried out easily and economically. This applies, in particular, to those areas of application in which it is desirable to obtain a product with good resistance to aging when heated, to the action of solvents and / or chemicals that cause corrosion, and resistance to creep is of great importance.
Known compositions based on fluoropolymers, for example, a copolymer of trifluoroethylene, fluoride vinylidene and perfluoroolefine Sh.
However, these compositions have low technical characteristics.
Closest to the technical essence of the invention is a polymeric composition containing a fluoropolymer copolymer of hexafen-propylene with vinylidene fluoride - and organic peroxide 2.
However, this curable composition also has low performance.
The purpose of the invention is to increase the resistance of the composition to heat, creep and the action of aggressive media.
The goal is achieved by
10 that composition I containing organic peroxide and a fluoropolymer contains as the last a copolymer, the polymerized units of which are
a) from links whose source
15 is a brominated olefin selected from the group including bromotrifluoroethylene, bromofluoroethylene, perfluoroallyl bromide, 4-bromo-3,3,4,4-tetrafluoro-Uten-1, 4-bromoperfluorobutene-1 and
20 vinyl bromide, in the amount of 0.372, 4 mol.%,
b) from the units whose source is monomers — 65-69.6 mol.% tetrafluoroethylene and 30-33.5 mol.% per25 fluoromethylperfluorovinyl ether; or 52–55 mol% tetrafluoroethylene, 31–45 mApp.% propylene and vinylidene fluoride residue, or 51–78 mol% vinylidene fluoride, 20–49 mol% hexafluoro 30
.propylene and / or tetrafluoroethylene and
the residue perfluoromethyl perfluorovinyl ether, in the following ratio of components, parts:
Fluoropolymer100
Organic
peroxide 0.5-10
The composition according to the invention may also contain 1-15 wt. Of magnesium oxide or calcium.
According to another embodiment of the invention, besides all the above components, it may contain trialisyl isocyanurate in the amount of 0.510 parts by weight.
The copolymer must have a sufficient number of units so that it contains approximately 0.3-1.5% by weight of bromine. Bromotrifluoroethylene is particularly recommended.
In one of the most preferred embodiments of the invention, the new copolymer is a fluoroelastomer, in which the component b consists of units, the source of which is approximately tetrafluoroethylene and perfluoromethylperfluorovinyl ether.
In other embodiments, the copolymer is a fluoropolymer, in which component b consists of units, the source of which are monomers in any of the above combinations,
In preparing the composition, it is recommended to use a free radical initiating agent, and to carry out a reaction to obtain a copolymer in the presence of free radical polymerization in an emulsion. Free radical initiating agents most suitable for such a reaction include ammonium persulphate, sodium persulphate, potassium persulphate, or mixtures of two or more of these compounds. Other water-soluble inorganic peroxide compounds are also suitable, for example, perphosphates, perborate and sodium, potassium and ammonium percarbonates. The initiator can be used in combination with a reducing agent such as sulfite, bisulfite, metabisulfite, hyposulfite, thiosulfate, phosphite or hypophosphite of sodium, potassium or ammonium, or in combination with a salt of ferrous iron, monovalent copper or silver or other easily oxidizable metal compound . It is also possible to use well-known organic: free radical free radical initiators,. preferably in combination with a surfactant such as sodium lauryl sulfate or ammonium perfluorooctonoate.
Surfactant can be selected from among those related. which it is known that they are successfully used in the preparation of fluoropolymers,
A surfactant can also be used with inorganic initiators.
During the emulsion polymerization reaction, known chain transfer agents may also be present, but in many cases this is not recommended.
After completion of the emulsion polymerization reaction carried out under the recommended conditions, the copolymer can be isolated from the polymer latex formed by known methods, for example, by coagulation, carried out with the introduction of electrolytes or by WEDGMoin followed by centrifuging or filtering and drying the copolymer
The reaction, in which the formation of a copolymer occurs, can also be carried out in a block method or in an organic liquid medium containing an organic free radical initiator. It is generally recommended that none of the organic liquids present should be a chain transfer agent.
During the preparation of the copolymer, the reaction mixture is preferably heated in a reactor in the presence of an inert gas at a temperature of 50ISOc and pressure above atmospheric, for example under a pressure of 7-140 kg / cm, preferably 35-105 kg / cm. In one of the most preferred options, the polymerization is carried out continuously and the average duration the reaction mixture stays in the reactor for about 5-30 minutes, and sometimes reaches 2-3 hours. The duration of the reaction can be calculated by dividing the reactor volume by the volume of latex formed per hour.
New fluoropolymer in most cases has a true viscosity of about 0.01 or higher, preferably about 0.2 to 1.2.
Dialkyl peroxide is preferably used as the organic peroxide. An organic peroxide is selected to serve as a curing agent for the composition in the presence of other components that will be present in the final composition, at curing temperatures not causing excessive curing during mixing or other operations prior to the curing process. Dialkyl peroxide is particularly desirable, decomposing at temperature, if the composition is to undergo processing, at elevated temperatures prior to its unscrewing. In many cases, di-tert-butyl peroxide can be used, in which a tertiary carbon atom is bound to the oxygen atom of a parecis group. To the most
Valuable peroxides of this type include 2,5-dimethyl-2,5-di- {tritbutillo) -hexene-3 and 2,5-dimethyl-2, 5-di- (t-butylperoxy) -hexane. As the peroxide, dicumyl peroxide, dibenzoyl peroxide, t-butyl perbenzoate and di-tl, 3-dimethyl-3- (tert-butyl-peroxide) -butil-carbonate, etc. can be used.
You can get the composition at room temperature in the form of a liquid film-forming composition containing an organic solvent to / or a diluent, applying a layer of liquid composition on a substrate, drying this layer and curing it at a temperature below.
The composition, which is a mixture of fluoropolymer and peroxide, is a marketable product that can be supplied to the manufacturers of finished products if they wish to modify the material with some other additives in accordance with the necessary requirements. Magnesium oxide or calcium and trilyl isocyanurate may be added to the composition.
The composition may also contain one or more targeted additives. By adding a suitable solvent, a liquid composition can be prepared, which can be used to produce adhesives, coatings, films, and the like.
When preparing the fluoropolymer composition, the copolymer can be mixed with other components using any known mixer, for example, a roller type rubber mixer or a closed type rubber mixer (Banbury) can be used to make the process at a temperature below the decomposition point of organic peroxide.
Curing of compositions containing the proposed components is, in most cases, recommended to be carried out by heating it for 160 minutes at a temperature of about 149,204 ° C. You can use conventional presses to cure rubber and harden plastic material. If it is desirable to obtain a product with maximum heat resistance and stability, it is recommended to carry out additional curing, in which the product is heated for about 1-48 hours at a temperature of about 180-300 ° C.
The following examples illustrate the invention. All quantities, except when it is particularly oroBofieHO, are expressed in weight percent and parts by weight.
