Abstract
The invention discloses a formula of high-viscosity modified polytetrafluoroethylene. The high-viscosity modified polytetrafluoroethylene comprises modified polytetrafluoroethylene synthetic resin, a plasticizer, a coupling reagent, a binder, a lubricant, an additive and a foaming agent, wherein the plasticizer is phthalic acid ester; the coupling reagent is titanate; the binder is modified novolac epoxy resin; the lubricant is molybdenum disulfide; the additive is a blending agent of a rare earth compound and rare earth oxide; the foaming agent is azodicarbonamide. With the adoption of the formula of the high-viscosity modified polytetrafluoroethylene, provided by the invention, the prepared high-viscosity modified polytetrafluoroethylene has special high viscosity, can provide a better adhesive property under special conditions, fills a blank in the prior technical field, is low in cost, and further has a higher market value.
Description
Technical field
The present invention relates to plastic formula field, particularly relate to a kind of high viscosity modified Teflon formula.
Background technology
Teflon plastics have excellent not viscosity, anti acid alkali performance, anti-various organic solvent properties and other preservative property usually, and under the extraordinary demand condition of part, too high not viscosity is often not necessary to element, even plays adverse effect.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of high viscosity modified Teflon formula, the high viscosity modified Teflon obtained is made to have special high viscosity, good caking ability can be provided under for extraordinary condition, in technical field, still genus is blank and with low cost, has good marketable value.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of high viscosity modified Teflon formula, comprise modified Teflon synthetic resins, softening agent, coupling agent, binding agent, lubricant, additive and whipping agent, described softening agent is phthalic ester, described coupling agent is titanic acid ester, described binding agent is Modified phenolic epoxy resin, described lubricant is molybdenumdisulphide, described additive is rare earth compound and rare earth oxide mixture, and described whipping agent is Cellmic C 121.
In a preferred embodiment of the present invention, described high viscosity modified Teflon each Ingredients Weight proportioning of filling a prescription is that modified Teflon synthetic resins accounts for 36% ~ 55%, softening agent accounts for 2% ~ 3%, coupling agent accounts for 7% ~ 9%, binding agent accounts for 20% ~ 25%, lubricant accounts for 3 ~ 7%, additive accounts for 11% ~ 15%, and whipping agent accounts for 2% ~ 5%.
In a preferred embodiment of the present invention, described high viscosity modified Teflon each Ingredients Weight proportioning of filling a prescription is that modified Teflon synthetic resins accounts for 36% ~ 54%, softening agent accounts for 2% ~ 3%, coupling agent accounts for 7% ~ 9%, binding agent accounts for 14% ~ 18%, lubricant accounts for 7 ~ 9%, additive accounts for 14% ~ 20%, and whipping agent accounts for 2% ~ 5%.
The invention has the beneficial effects as follows: a kind of high viscosity modified Teflon formula provided by the invention, the high viscosity modified Teflon obtained is made to have special high viscosity, good caking ability can be provided under for extraordinary condition, in technical field, still genus is blank and with low cost, has good marketable value.
Embodiment
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A kind of high viscosity modified Teflon formula, comprise modified Teflon synthetic resins, softening agent, coupling agent, binding agent, lubricant, additive and whipping agent, described softening agent is phthalic ester, described coupling agent is titanic acid ester, described binding agent is Modified phenolic epoxy resin, described lubricant is molybdenumdisulphide, and described additive is rare earth compound and rare earth oxide mixture, and described whipping agent is Cellmic C 121.
Wherein, described high viscosity modified Teflon each Ingredients Weight proportioning of filling a prescription is that modified Teflon synthetic resins accounts for 36% ~ 55%, softening agent accounts for 2% ~ 3%, coupling agent accounts for 7% ~ 9%, binding agent accounts for 20% ~ 25%, lubricant accounts for 3 ~ 7%, and additive accounts for 11% ~ 15%, and whipping agent accounts for 2% ~ 5%.By the way, adhesive property is strengthened.
Further, described high viscosity modified Teflon each Ingredients Weight proportioning of filling a prescription is that modified Teflon synthetic resins accounts for 36% ~ 54%, softening agent accounts for 2% ~ 3%, coupling agent accounts for 7% ~ 9%, binding agent accounts for 14% ~ 18%, lubricant accounts for 7 ~ 9%, and additive accounts for 14% ~ 20%, and whipping agent accounts for 2% ~ 5%.By the way, by expanding the mode of contact surface, indirectly adhesive property is promoted.
Can debug according to different ratios according to different demand, thus reach different results of use.
In sum, the invention provides a kind of high viscosity modified Teflon formula, the high viscosity modified Teflon obtained is made to have special high viscosity, good caking ability can be provided under for extraordinary condition, in technical field, still genus is blank and with low cost, has good marketable value.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
