Abstract
The invention relates to a processing method for improving demoulding effect by utilizing a copolymer film, which is applied to a mould, and the processing method comprises the steps of mixing a perfluoroalkyl compound and a reinforcing material into a mould release agent, and then uniformly coating the mould release agent on the inner wall surface of a containing groove of the mould; baking the mold to enable the release agent to form a copolymer film; then, the multi-layer composite materials are sequentially placed into the mold to perform a laminating procedure, so that the composite materials can be combined into a composite finished product. Because the copolymer film formed by the perfluoroalkyl compound and the reinforcing material has the characteristics of high wear resistance, high adhesion resistance and low friction, under the condition that the composite finished product is taken out from the accommodating groove, the copolymer film can not be adhered to the composite finished product completely, and can be completely retained in the accommodating groove, and the copolymer film does not need to be coated again before the laminating procedure is carried out every time, so that the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of processing method utilizing copolymer film to promote stripping result, espespecially by fluoroalkyl compound
The releasing agent formed with strengthening material is coated on mould, and via baking, to form the place of copolymer film in a mold
Reason method.
Background technology
Composite is a kind of material that two or more raw materials (such as: metal, pottery, macromolecule) is combined into one
Material, owing to it has high temperature resistant, high intensity, high rigidity, the characteristic such as lightweight, corrosion-resistant, therefore in recent years by all trades and professions
Favor, and it is used in the different aspects such as aviation field, medical field, sports equipment field and equipment of industrial product field in a large number
On.
Composite includes two parts altogether: base material (matrix) and Rankine (reinforcement), Rankine many with
The form of granule, thin slice, chopped fiber and continuous fiber is dispersed in base material, and the physics with high rigidity and high intensity is special
Property, wherein, universal with fibrous Rankine again, but owing to fibrous Rankine cannot undertake axial pressure, therefore
Under unshielded situation, the surface of fiber is highly susceptible to the erosion of Environmental Chemistry composition, and produces defect on surface, because of
This, Rankine must also combine with base material, could form firm durable structure.
Conventional base material includes various thermosetting and thermoplastic macromolecule material, and the former includes unsaturated polyester resin
(unsaturate dpolyester), epoxy resin (epoxy), phenolic resin (phenolic) etc., the latter then includes polypropylene
(PP), polyether-ether-ketone (PEEK), nylon (nylon) etc..So-called thermosetting, after referring to macromolecule once polymerization forming, due to
There is between macromolecule the link (cross-linking) of varying degree, therefore heat and will be unable to make it melt, and only can promote its point
Solve；As for thermoplastic matrix, after referring to macromolecule once polymerization forming, owing to high molecular molecular shape is biased into linearly, and
It is the secondary bond bond more weak with intensity between macromolecule, allows the slip that macromolecule catch cropping is relative, therefore heat and it can be made to melt
Flowing.
General speech, multilayer materials, by " folded patch program ", is combined into one by the many meetings of those skilled in the art, folded patch
The practice of program differs, and the common practice includes: hand laying coating and spray up method (hand lay-up and spray
Placement technique), automatization fiber put method (automatic fiber place-ment technique),
Prepreg cloth lamination shapes (pre-impregnated tape laying method), resin transfer shapes (resin
Transfer molding, RTM) etc., but, no matter using which kind of mode, those skilled in the art are performing this folded patch program
Before, all need first coated release agent (also known as mould release) in mould, so, after folded patch program completes, those skilled in the art
The composite finished product that could be successfully formed by these composites is taken out by this mould, and asking of being unlikely to stick
Topic.But, the releasing agent used in the past, after folded patch program completes, although composite finished product can be made successfully to be taken out by mould,
But can attach the releasing agent of part on composite finished product, therefore, after taking out this composite finished product, those skilled in the art must also
This composite finished product is polished, the releasing agent sticked on this composite finished product could be removed, consequently, it is possible to not only can significantly drag
Prolong production procedure, and also affect quality and the yield of composite finished product.
Therefore, inventor then expects, if can improve known releasing agent？So that those skilled in the art exist
When carrying out the folded patch program of composite, this composite and mould can be completely cut off by thin film, with after completing this folded patch program,
This composite finished product can be taken out by those skilled in the art easily by mould, and need not again spray releasing agent, and can be direct
Carry out folded patch program next time, therefore how releasing agent and known processing mode are improved, aforesaid many to solve
Problem, becomes the major issue that the present invention wants to solve at this.
Summary of the invention
Because known releasing agent can be built-up on the finished product of composite, cause those skilled in the art entering every time
Before and after the folded patch program of row, it is necessary to again spray releasing agent the problem that composite finished product is polished, inventor by feat of
Practical experience for many years and Professional knowledge, after experiment test repeatedly, finally design one and utilize copolymer film
Promote the processing method of stripping result, it would be desirable to improve the problems of known technology.
One purpose of the present invention, is to provide a kind of processing method utilizing copolymer film to promote stripping result, this process
