The invention relates to a chemical transfer membrane coating process for an automobile carbon fiber composite. The chemical transfer membrane coating process is characterized by comprising the following specific coating steps that the surface of a carbon fiber composite workpiece is cleaned; a coating chemical transfer membrane is prepared; a lining layer of the transfer membrane is removed; the chemical transfer membrane is stretched and pulled according the shape of the surface of the carbon fiber composite workpiece; a paper lining or a polyvinyl chloride lining of the outer surface of the chemical transfer membrane is removed; and the transfer membrane is coated on the carbon fiber composite workpiece. By adoption of the chemical transfer membrane coating process for high-decorativeness and high-performance automobile parts made from the carbon fiber composite, the technical problems existing in the chemical transfer membrane coating process are solved.
Description
Technical field
The present invention relates to a kind of chemical transfer membrane coating processes of automobile carbon fibre composite, more particularly to a kind of to use
The chemical transfer membrane coating processes of high-decoration, high-performing car parts made by carbon fibre composite, belong to coating and
Application techniques field.
Background technology
In recent years, with the needs that automotive light weight technology develops, the technical advantage that carbon fibre composite is projected with it is in vapour
The application in car field is more and more, can be used to manufacture body of a motor car, wheel hub, primary structure member, power transmission shaft, engine mount and its inside
Component.Present F1 racing cars（World's First-order equation championship）, vehicle body major part structure all use carbon fibre material.But, due to
The reason such as the complexity of its preparation technology and the high cost of raw material, current carbon fiber application is not also extensive.It is especially domestic at present
The preparation means and technique of carbon fibre composite are all relatively backward, using the coating material and work of conventional other composites
Skill, is extremely difficult to the technical requirements of vehicle exterior cladding element.
At home and abroad in the inquiry of patent, Patents are described as follows with the difference of the present invention：
（1）Application（Patent）Number：CN200910132378.6《The production of the carbon fiber sheet with low curvature and surface coating
Method》It is related to a kind of production method of the carbon fiber sheet with low curvature and surface coating.Comprising 1 lamination laminating step, 2
Glued membrane pastes step, 3 hot pressing hardened forming steps and 4 coating spraying process.Lamination laminating step is first carried out with lamination type ground heap
Resiniferous plastic type carbon fiber raw material piece obtains carbon fiber raw material sheet material in folded, then carries out glued membrane and paste step to dissolve in
The glued membrane of paint solvent is covered on carbon fiber sheet, and then carrying out hot pressing hardened forming step will be covered with the carbon fiber of glued membrane
Raw material sheet material is placed in hot pressing hardened forming in mould, finally directly coating is sprayed at into carbon fiber sheet half with coating spraying process
On the glued membrane of finished product, make coating combine closely with glued membrane, the carbon fiber sheet with low curvature and surface coating is obtained.This
It is bright develop it is a kind of can be with direct spraying coating, to produce the producer of the carbon fiber sheet with application after hot-forming
Method.But the carbon fiber sheet that the production method is obtained, although the production process with application, but coating process is excessively simple, no
High-decoration, the high-performance coating of suitable automobile product can be produced.It is entirely different with the principal claim of the present invention.
（2）Application（Patent）Number：CN201210042627.4《A kind of coating process of carbon fiber fishing rod》A kind of carbon is provided
Fiber fishing rod coating process.The fishing rod coating process concrete steps are followed successively by degreasing, decontamination, cleaning and the baking of first fishing rod
It is dry, and pole mouth is clogged using the sealing of silica gel head；Be vertically hung on hanger cross numerical control DISK electrostatic spraying devices its carry out
Levelling area levelling 10-15 minutes are entered after lower reciprocation type spray painting, then afterwards by far infrared irradiation 8-15 minutes, it is carried out solid
Change.The implementation result invented using this, fishing rod surface is smooth full, and dead angle position painting rate is high, and overall japanning is uniform, and brightness is high,
Adhesive force is good, it is ensured that product quality is stable, is not in aberration, the bad phenomenon such as foaming, and it is thin that paint paint film takes out paint than tradition
50%, and the paint of whole fishing rod is few, it is lighter than traditional japanning mode, experienced operator is independent of, spray painting is rapid, efficiency high.
This with the present invention be more particularly directed to the Spray Painter of high-decoration, high-performing car parts made by a kind of use carbon fibre composite
Skill, is diverse.Patent in terms of the other coating process also on the dry body of carbon fiber golf clubs, with above-mentioned original
Because similar, with the present invention be more particularly directed to field and technical requirements it is entirely different.
The content of the invention
In order that carbon fibre composite is extensively applied on body of a motor car and parts, it is an object of the invention to carry one
The chemical transfer membrane coating processes of kind of automobile carbon fibre composite, its use high-decoration made by carbon fibre composite,
