Abstract
The invention belongs to polytetrafluoroethylene fibre field, it is that the fibre strength that manufactures for the manufacturing method of the short fibres of existing PTFE is relatively low and the manufacturing method of the short fibres of a kind of PTFE that provides.Include the following steps：Then the raw material prepared is poured into agitator stirring by preparation raw material first, the oil spout simultaneously in whipping process, and stirring 15 minutes, reversion stirring 15 minutes are rotated forward when stirring；The keg installed is put into incubator and carries out heat preservation stewing process, for the control of heat preservation the temperature inside the box at 45 degree, time of repose is 12 hours；Product by heat preservation is taken out into precompressed and is forced into billet；60 degree of water tanks are then placed in stand；Finally carry out press mold, degreasing, sintering stretching, comb modeling, sizing, cutting.This method is differed using raw material particle size size is combined carry out dispensing, and by positive and negative rotation, and the method can be after kerosene infiltration, sized molecules have better compatibility, and molecule is even closer to be connected, and it is more preferable to be sintered intensity in drawing process, lower, the intensity higher of fiber is lost.
Description
Technical field
The invention belongs to polytetrafluoroethylene fibre field more particularly to a kind of manufacturing methods of the short fibres of PTFE.
Background technology
PTFE is the abbreviation of polytetrafluoroethylene (PTFE), and the raw material of the existing short fibres of PTFE uses the polytetrafluoroethylene (PTFE) with grain size, together
Compatibility after being mixed between the polytetrafluoroethylene (PTFE) of grain size between each particle is poor, and the molecule of particle is connected not closely, is being sintered
Intensity is low when stretching process, and the fibre strength after being made is relatively low.
Invention content
It is relatively low purpose of the present invention is to the fibre strength manufactured for the manufacturing method of the short fibres of existing PTFE and provide
A kind of short fibres of PTFE manufacturing method.
The present invention is achieved by the following technical solution：
A kind of manufacturing method of the short fibres of PTFE, includes the following steps：
Then the raw material prepared is poured into agitator stirring, is sprayed simultaneously in whipping process by step 1, first preparation raw material
Oil rotates forward stirring 15 minutes, reversion stirring 15 minutes when stirring；
The product stirred evenly in step 1 is distributed into keg by step 2；
The keg installed in step 2 is put into incubator and carries out heat preservation stewing process by step 3, keeps the temperature the temperature inside the box
At 45 degree, time of repose is 12 hours for control；
Product by heat preservation in step 3 is taken out precompressed and is forced into billet by step 4；
Product in step 4 is put into 60 degree of water tanks and stood by step 5；
Product in step 5 is sequentially carried out press mold, degreasing, sintering stretching, comb modeling, sizing, cutting by step 6.
The oil sprayed in the step one is kerosene.
Raw material in the step one is the different polytetrafluoroethylene material of two kinds of grain sizes.
The distribution ratio of two kinds of stock diameters is 300-350 μm：480-550 μm, kerosene dosage and total pellet weight
Than being 40：17 to 40：Any proportion in 20 ranges.
Beneficial effects of the present invention：This method is differed using raw material particle size size and is combined carry out dispensing, and by just
Reversion, the method can be after kerosene infiltrations, and sized molecules have better compatibility, and molecule is even closer to be connected, and sintering stretches
Intensity is more preferable in the process, and lower, the intensity higher of fiber is lost.
Specific implementation mode
With reference to embodiment, the invention will be further described.
Embodiment
A kind of manufacturing method of the short fibres of PTFE, includes the following steps：
Then the raw material prepared is poured into agitator stirring, is sprayed simultaneously in whipping process by step 1, first preparation raw material

Product in step 4 is put into 60 degree of water tanks and stood by step 5；
Product in step 5 is sequentially carried out press mold, degreasing, sintering stretching, comb modeling, sizing, cutting (this paper by step 6
Middle press mold, degreasing, sintering stretch, comb modeling, sizing, cutting technique be existing industry in common process, the technique is more ripe, with
The technical problems to be solved by the invention are not related, therefore just do not elaborate herein).
The oil sprayed in the step one is kerosene.
Raw material in the step one is the different polytetrafluoroethylene material of two kinds of grain sizes.
The distribution ratio of two kinds of stock diameters is 300-350 μm：480-550 μm, kerosene dosage and total pellet weight
Than being 40：17 to 40：Any proportion in 20 ranges.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, those ordinary skill in the art's simply changes
All it is within protection scope of the present invention with replacing.
