Problems solved by technology

In the existing method for preparing fiber pipes with text information such as patterns, patterns or trademarks on the surface, the protective layer on the surface of the prepared pipes is easily damaged by rubbing, and the text information such as patterns or trademarks is easily damaged, destroying the pipe and its surface. The appearance of the finished product affects the appearance quality
Such as all kinds of fiber fishing rods, carbon fiber bicycles, decorative profiles and other products made of fiber pipes, in the process of production and use, there will inevitably be scratches, rubbing, bumping, etc., damage to the protective layer, patterns or trademarks on the surface, etc. Text information is easy to break away from the pipe and be damaged, affecting its appearance
Lacquering or spraying paint to form a protective layer, the preparation process is complicated, the workload is increased, raw materials are wasted, and the manufacturing cost is high

[0029] A method for preparing a fiber pipe with patterns or characters on its surface, comprising the following steps:

[0030] 1) Take up the fiber prepreg on the mandrel to form a tube blank;

[0031] 2) Print the pattern or text reverse ink on one side of the plastic film, wherein the ink contains 0.8-1.5 parts of colorant, 8-15 parts of binder, 10-20 parts of filler, diluted The agent is 20-85 parts; usually the connecting material is gold-adjusting oil, the filler is talcum powder or calcium bicarbonate, and the diluent is ethanol;

[0032] 3) The side of the plastic film with patterns or characters is opposite to the pipe blank, and wrapped on the pipe blank by winding a release tape, instead of the release tape, the pipe blank is shaped;

[0033] Or the side of the plastic film with patterns or characters is opposite to the pipe blank, not completely covered and wound on the outer layer of the pipe blank or partially laminated and wound on the outer layer of the pipe b...

[0047] A method for preparing a fiber pipe with patterns or characters on its surface, comprising the following steps:

[0048] 1) Take up the fiber prepreg on the mandrel to form a tube blank;

[0049] 2) Print the pattern or text reverse ink on one side of the plastic film, wherein the ink contains 0.8 parts of colorant, 15 parts of gold-adjusting oil, 10 parts of talcum powder, and 85 parts of ethanol according to the proportion by mass;

[0050] 3) Put the plastic film with the pattern or text on the opposite side of the tube blank, and not completely cover the outer layer of the tube blank (that is, the outer layer of the tube blank in the shape of a spiral spring or intersecting with each other), and then wrap the release tape stereotypes;

[0051] 4) Put the wrapped pipe blank into the curing furnace and bake it at 120°C, so that the pattern or text ink on the plastic film and the phenolic resin or epoxy resin of the pipe blank are immersed in each other, and baked for...

Abstract

The invention relates to a preparation method of a fiber pipe with a pattern or a letter on the surface. The preparation method comprises the following steps of: 1) winding fiber prepreg on a core mold to form a pipe blank, 2) printing reverse pattern or letter ink on one side of a plastic film, 3) winding the plastic film on the pipe blank to replace a release belt to size the pipe blank, or winding in an incomplete covering or partial overlying manner, then winding the release belt for sizing, 4) placing the wound pipe blank in a curing oven for baking for 1-3h at 110-175 DEG C to allow the pattern or letter ink on the plastic film and phenolic resin or epoxy resin of the pipe blank to be immersed mutually, solidified and formed, and 5) removing the mold, and stripping the plastic film to obtain the finish product. The preparation method has the advantages that the pattern is not easy to separate and damage, paint polishing or paint spraying is not required during preparation, the preparation technology is simple, the time, labor and raw materials are saved, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a method for preparing a fiber pipe, in detail, a method for preparing a fiber pipe with a pattern or text on the surface that is not easily damaged, has a simple preparation process, and is low in cost. Background technique [0002] We know that existing fiber pipes include carbon fiber pipes, glass fiber pipes and graphite fiber pipes. Due to the advantages of light weight, high strength, good toughness, strong shock resistance, corrosion resistance, etc., fiber pipes have gradually replaced aluminum alloy pipes and are used in more and more fields, such as: manufacturing fishing rods, making clothes Frames, bicycle manufacturing, interior decoration profiles and other fields. The existing method for preparing fiber pipes with text information such as patterns or trademarks on the surface includes the following steps: 1. Winding the fiber prepreg on the mandrel; 2. Winding the release tape; 3. Putting it into a curing furnac...
