Embodiment 1

[0024] The thickness of the functional layer of the coated chemical transfer film is 100 μm-250 μm and the thickness of the functional varnish layer is 50 μm-100 μm. For its process, see figure 2 , take the following steps:

[0025] (1) Cleaning: Visually inspect the surface of the carbon fiber composite workpiece ( figure 1 , 0 layers), no dust;

[0026] (2) Sticking: Remove the lining layer of the chemical transfer film to expose the adhesive layer, and attach the transfer film to the surface of the carbon fiber composite workpiece.

[0027] (3) Baking: Stretch and pull the chemical transfer film according to the surface shape of the carbon fiber composite material workpiece, and heat the chemical transfer film with a hand-held infrared heating lamp. The purpose is to make the functional layer and functional varnish layer according to the shape of the carbon fiber composite material workpiece. Appropriate deformation. Use a tool to remove the air bubbles between the tra...

Embodiment 2

[0034] The thickness of the functional layer of the coated chemical transfer film is less than 100 μm and the thickness of the functional varnish layer is less than 50 μm. For its process, see figure 2 , take the following steps:

[0035] (1) Cleaning: Visually inspect the surface of the carbon fiber composite workpiece without dust;

[0036] (2) Sticking: Remove the lining layer of the chemical transfer film to expose the adhesive layer, and attach the transfer film to the surface of the carbon fiber composite workpiece.

[0037] (3) Baking: Stretch and pull the chemical transfer film according to the surface shape of the carbon fiber composite workpiece, and heat the chemical transfer film with an infrared heating lamp. In this process, the functional layer and the functional varnish layer deform greatly, are easy to wrinkle, and are easy to be damaged due to stretching after heating and baking.

[0038] (4) Modification: remove the paper lining or polyvinyl chloride lin...

Embodiment 3

[0044]The thickness of the functional layer of the coated chemical transfer film is greater than 250 μm and the thickness of the functional varnish layer is greater than 100 μm. For its process, see figure 2 , take the following steps:

[0045] (1) Cleaning: Visually inspect the surface of the carbon fiber composite workpiece without dust;

[0046] (2) Sticking: Remove the lining layer of the chemical transfer film to expose the adhesive layer, and attach the transfer film to the surface of the carbon fiber composite workpiece.

[0047] (3) Baking: Stretch and pull the chemical transfer film according to the surface shape of the carbon fiber composite workpiece, and heat the chemical transfer film with an infrared heating lamp. This process is prone to problems such as coating cracking due to heating of the thicker functional layer and functional varnish layer.

[0048] (4) Modification: remove the paper lining or polyvinyl chloride lining on the outer surface of the chemi...

Abstract

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 [0001] The invention relates to a chemical transfer film coating process of carbon fiber composite materials for automobiles, in particular to a chemical transfer film coating process of highly decorative and high-performance auto parts made of carbon fiber composite materials, belonging to coatings and coatings. technology field. Background technique [0002] In recent years, with the development of lightweight automobiles, carbon fiber composite materials have been used more and more in the automotive field due to their outstanding technical advantages. Internals. In the current F1 racing car (Formula One World Championship), most of the body structure is made of carbon fiber materials. However, due to the complexity of its preparation process and the high cost of raw materials, carbon fiber is not widely used at present. In particular, the preparation methods and processes of domestic carbon fiber composite materials are relatively backward at present, ...
