Description
Technical field
The present invention relates to the manufacture fields of carbon fiber product in sports goods, and in particular to a kind of carbon fiber processing polymerization
Film.
Background technique
Carbon fiber product conduct is widely used in sports goods to process raw material.The carbon fiber product in sports goods at present
Manufacture field, the non-uniform problem of the generally existing mobility of carbon fiber product resin in forming process, causes carbon after molding
Fibre skin breakage, and surface is caused phenomena such as incomplete, pin hole occur.These problems all seriously reduce carbon fiber
The impact strength of product.
Many enterprises take the mode scrapped to handle for serious product is ruptured, and product defective for surface is adopted
The mode for mending soil plus polishing is taken to handle.However rupture can be all generated after many carbon fiber product high-temperature moldings, if all taken
The mode of scrapping, which is handled, will greatly increase production cost.The processing of earthwork formula is mended if taken, the carbon fiber product after overfill soil
Impact strength cannot be guaranteed.In addition, mending, geotechnological sequence is more complicated, this will will increase additional labor intensity, causes to give birth to
Produce inefficiency.
In view of this, the present inventor develops one on the basis of by long-term practice and a series of research and test
Kind carbon fiber polymer film for processing can form protective film on carbon fiber product surface, thus this case generate.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of carbon fiber polymer film for processing.The present invention mainly applies
The processing of carbon fiber product in sports goods forms protective film on carbon fiber product surface, can effectively promote carbon fiber system
The impact strength of product and the polishing processing performance of subsequent forming product.
In order to achieve the above objectives, the present invention is achieved by the following technical solutions:
1. a kind of carbon fiber polymer film for processing, is mixed by following components by weight:
Wherein above-mentioned epoxy resin is E-51 epoxy resin.
Wherein above-mentioned promotor is imidazoles promotor.
The main reason for surface of carbon fiber product is out-of-flatness, rupture is the epoxy since carbon cloth is in hot setting
Caused by resin flows solidification unevenness in mold.The present invention is mainly to provide a kind of polymeric membrane, can be wrapped in carbon cloth or carbon.
Fibre outer surface enters mold hot setting together with product, forms one layer in product surface after the completion of solidification
Protective film, accordingly even when carbon fiber product surface is defective, polymeric membrane can also cover in defect.Furthermore polymeric membrane is enclosed with carbon
Cloth can prevent carbon fiber product from rupturing, and greatly increase the impact strength of product.
The intensity and toughness of carbon fiber product can be increased using polymeric membrane produced by the invention.The polymeric membrane is by a variety of high
Intensity polymer composite composition, has excellent anticollision performance.It and epoxy resin system compatibility and binding performance
It is all very good.Original processing conditions will not be changed using the polymeric membrane, only wrap up a tunic on the surface of carbon cloth,
Using simple, conveniently, there is very extensive application prospect.
Specific embodiment
Carbon fiber polymer film for processing is prepared, weigh raw material (kilogram) by following components and proportion and is mixed:
Polymeric membrane obtained is wrapped in carbon cloth or carbon fiber product outer surface, then mold high temperature is placed in together with product
Solidification forms layer protecting film in product surface after solidification.
Embodiment 1:
Carbon fiber polymer film for processing is prepared, weigh raw material (kilogram) by following components and proportion and is mixed: E-51 epoxy
Resin 30, novolac epoxy resin 25, nitrile rubber 5, butanone 20, dicyandiamide 10, imidazoles promotor 1, white carbon black 3, carbon black 3,
3 polymeric membrane of amine normal temperature cure agent it is as follows the step of making and using:
(1) nitrile rubber first is dissolved with butanone, adds E-51 epoxy resin, novolac epoxy resin；
(2) dicyandiamide, imidazoles promotor, carbon black, white carbon black are added in (1) upon dissolution, stirs evenly；
(3) configured product is uniformly coated on carbon cloth, then sprays upper amine normal temperature cure agent in the sprinkling of its surface,
It can be used within placement 3 hours or more；
(4) polymeric membrane is cut into required size；
(5) polymeric membrane cut out is coated on outside carbon fiber strip, or polymeric membrane is placed on to the phase of carbon fiber strip
Close position.
Original processing conditions will not be changed when the polymeric membrane use prepared in the present embodiment, only in carbon cloth
A tunic is wrapped up on surface, does not change original technique.The polymerization film toughness, intensity are most ideal, best with the associativity of carbon cloth, use
Simply, conveniently, there is very extensive application prospect.
Embodiment 2:
Carbon fiber polymer film for processing is prepared, weigh raw material (kilogram) by following components and proportion and is mixed: E-51 epoxy
Resin 30, novolac epoxy resin 15, nitrile rubber 6, butanone 30, dicyandiamide 5, imidazoles promotor 1, white carbon black 5, carbon black 2,
Amine normal temperature cure agent 6.
The polymeric membrane is made and used according to the step in embodiment 1.
The polymeric membrane being prepared can increase the intensity of carbon fiber product and the binding strength with carbon cloth.The polymeric membrane by
A variety of high intensity polymer composite compositions, have excellent intensity, with epoxy resin system compatibility, excellent bonding performance.
Embodiment 3:
Carbon fiber polymer film for processing is prepared, weigh raw material (kilogram) by following components and proportion and is mixed: E-51 epoxy
Resin 32, novolac epoxy resin 18, nitrile rubber 8, butanone 25, dicyandiamide 6, imidazoles promotor 1, white carbon black 4, carbon black 2,
Amine normal temperature cure agent 4.
The polymeric membrane being prepared can increase the toughness of carbon fiber product.The polymeric membrane is answered by a variety of high-intensitive macromolecules
Condensation material composition, there is excellent anticollision performance.
It is appreciated that the variation of many details is possible, but therefore this does not violate scope and spirit of the present invention, appoint
The appropriate variation what person of an ordinary skill in the technical field does it, all should be regarded as the model for not departing from the invention patent
Farmland.
