Step is substituted or is cancelled.Thus it is proposed that a kind of product and its manufacturing method of alternative composite material product surface lacquer, are used
To solve the above problem.
Summary of the invention
The present invention provides a kind of product of alternative composite material product surface lacquer and its manufacturing method and can effectively solve
The problems in above-mentioned background technique.
To achieve the above object, the invention provides the following technical scheme: a kind of alternative composite material product surface lacquer
Product and its manufacturing method are made of polymer matrix composites product and a kind of film.
Further, the polymer matrix composites product is made of carbon fiber, glass fibre, aramid fiber and flax fiber
Resin base fiber cloth.
Further, the manufacturing method of the product of the alternative composite material product surface lacquer is the following steps are included: step
S1 provides a kind of film；
Step S2 provides the pre- fiber cloth for being soaked with resin, and the scrim cloth is stacked in film surface by multilayer, pays attention to keeping close
Fitting discharge air；
Step S3 keeps the multi-layer fiber cloth being layered on film hot-forming.
Further, the step S3 includes that will be laminated in the film merging mold of fiber cloth, first carries out hot-pressing processing, then into
Row cold pressing treatment.
Further, the step S3, which is included in front of the hot-pressing processing, passes through the heating mold, to being layered on film
The multi-layer fiber cloth carry out preheating and vacuumize process, make to be layered in the multi-layer fiber cloth on film and be heated to 80-110
At a temperature of degree Celsius and persistently vacuumize a period of time.
Further, the hot-pressing processing includes so that the temperature for the multi-layer fiber cloth being layered on film is 130-160
Degree Celsius, and hot pressing 20-25 minutes under the pressure of 10-15 atmospheric pressure.
Further, the cold pressing treatment includes so that the temperature for the multi-layer fiber cloth being layered on film is taken the photograph for 40-50
Family name's degree, and hot pressing 15-20 minutes under the pressure of 10-15 atmospheric pressure.
Further, including the demoulding step after the step S3, so that the multi-layer fiber cloth after solidifying be made to demould.
Compared with prior art, beneficial effects of the present invention: present invention omits polishing-primer spray-polishing-primer sprays-
The multi-layer fiber cloth for being soaked with resin in advance is layered in film surface and then curing molding i.e. by polishing-topcoating more to process, the present invention
Can, the product of class lacquered surface effect is just obtained, production efficiency is not only largely improved, improves production yield, and
And environmental pollution is greatly reduced, greatly reduce production cost；
The method of curing molding manufactures composite material system and then the multi-layer fiber cloth for being soaked with resin in advance is layered in film surface
Product, the different shaping according to mold obtain various different products, avoid Traditional paint spray different shaping product and need using different
The work of jig and adjustment torch parameters, adjustment paint parameters etc..
Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described, it should be understood that preferred embodiment described herein is only used
In the description and interpretation present invention, it is not intended to limit the present invention.
Embodiment one:
The present invention provides a kind of product of alternative composite material product surface lacquer, by polymer matrix composites product and a kind of film
Composition, the polymer matrix composites product are fine by the resin base that carbon fiber, glass fibre, aramid fiber and flax fiber form
Wei Bu；A kind of manufacturing method of the product of alternative composite material product surface lacquer is the following steps are included: step S1, provides one kind
Film；Step S2 provides the pre- fiber cloth for being soaked with resin, and the scrim cloth is stacked in film surface by multilayer, pays attention to keeping close
Fitting discharge air；Complete fiber cloth film surface it is reliable stacked after, need the fiber cloth that will be laminated solidification, to finally make
Product needed for obtaining.Before curing, it will be laminated in the die cavity of film merging mold of fiber cloth, thus the system of shape needed for being formed
Product can choose different molds, according to the different size shapes of product to correspond to each other in product.Step S3 makes to be laminated
Multi-layer fiber cloth on film is hot-forming.The step S3 includes that will be laminated in the film merging mold of fiber cloth, is first carried out
Hot-pressing processing, then cold pressing treatment is carried out, by being heated to the mold, so that the multi-layer fiber cloth temperature is increased.This
Sample enables the pre- resin being immersed in above fiber cloth to melt, and has good mobility in the die cavity of mold, to be formed good
Good surface effect, so that product has good appearance；In warm, mold sealing, holding is persistently vacuumized
State, under normal circumstances, the temperature of multi-layer fiber cloth described in the pre-heat treatment are heated to 80-110 degrees Celsius, and persistently vacuumize one
The section time.The step S3 passes through the heating mold before being included in the hot-pressing processing, described more on film to being layered in
Layer fiber cloth carries out preheating and vacuumize process, makes to be layered in the multi-layer fiber cloth on film and is heated to 80-110 degrees Celsius
At a temperature of and persistently vacuumize a period of time.The hot-pressing processing includes the temperature so that the multi-layer fiber cloth being layered on film
Degree is 130-160 degrees Celsius, and hot pressing 20-25 minutes under the pressure of 10-15 atmospheric pressure.The cold pressing treatment include so that
The temperature for being layered in the multi-layer fiber cloth on film is 40-50 degrees Celsius, and the hot pressing under the pressure of 10-15 atmospheric pressure
15-20 minutes.Including the demoulding step after the step S3, to make the multi-layer fiber cloth after solidifying demould, if needed
It well to demould, mould release is smeared in the die cavity of mold, fast demoulding after then forming.After obtaining product, defeathering is removed
Side can obtain the product of the appearance of class examination spray painting processing.
The present embodiment is due to being omitted polishing-primer spray-polishing-primer spray-polishing-topcoating more to process, not only pole
Production efficiency is improved in big degree, production yield is improved, and greatly reduce environmental pollution, greatly reduces and be produced into
This.
Finally, it should be noted that being not intended to restrict the invention the foregoing is merely preferred embodiment of the invention, to the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, for those skilled in the art, still can be with
