Abstract
The invention discloses a protective film for electronic components. The protective film is composed of the following components in parts by weight: 55-70 parts of epoxy resin, 15-22 parts of phenolic resin, 3-6 parts of colloidal graphite powder, 5-12 parts of tin oxide, 5-9 parts of titanium dioxide, 7-14 parts of bentonite, 2-7 parts of a dispersant, and 10-18 parts of a thinner. The protective film for the electronic components provided by the technical scheme of the invention forms a stable coating film layer, and has excellent weatherability and radiation protection and antistatic abilities, and the film is stable in structural properties, and can protect the electronic components permanently, so that the damage on the electronic components caused by external factors is reduced.
Description
Technical field
The present invention relates to a kind of protective membrane, particularly a kind of protective membrane of electronic component.
Background technology
Electronic component is the strength member that forms electronics or electromechanical equipment, volume is relatively little and more scattered, is easily subject to the impact of environmental factors, and occurs oxidation, distortion or other infringement, cause the function of electronic component to be affected, bring harm even to whole equipment.Comprise air, humiture, radiation etc. from the factor of environment, all can cause damage to electronic component, therefore it is most important on the impact of electronics to reduce environmental factors.Existing guard method, improves from structure mostly, or selects different materials, but effect is still limited, and cost is higher, and cost performance is lower.
Summary of the invention
Goal of the invention: for above-mentioned deficiency, the object of this invention is to provide a kind of protective membrane of electronic component.
Technical scheme of the present invention: a kind of electronic component protective membrane; wherein, protective membrane is made up of the component of following mass fraction: epoxy resin 55-70 part, resol 15-22 part, gluey Graphite Powder 99 3-6 part, stannic oxide 5-12 part, titanium dioxide 5-9 part, wilkinite 7-14 part, dispersion agent 2-7 part and thinner 10-18 part.
As preferably, dispersion agent is the one in tripoly phosphate sodium STPP, Sodium hexametaphosphate 99 or polyacrylamide.
As preferably, thinner is toluene or acetone.
Beneficial effect: the electronic component protective membrane that technical solution of the present invention provides; form the stable coated membrane structure of one deck; there is good weathering resistance and radioprotective, anti-static ability; and membrane structure stable in properties; protection electronic component that can be lasting, reduces the infringement that foeign element causes electronic component.
Embodiment
In order further to understand the present invention, below in conjunction with embodiment, the preferred embodiment of the invention is described, but should be appreciated that these are described is for further illustrating the features and advantages of the present invention, rather than limiting to the claimed invention.
Embodiment 1
A kind of electronic component protective membrane, wherein, protective membrane is made up of the component of following mass fraction: 10 parts of 55 parts of epoxy resin, 15 parts, resol, 3 parts of gluey Graphite Powder 99s, 5 parts, stannic oxide, 5 parts of titanium dioxides, 7 parts of wilkinites, 2 parts of tripoly phosphate sodium STPPs and toluene.
Embodiment 2
A kind of electronic component protective membrane, wherein, protective membrane is made up of the component of following mass fraction: 18 parts of 70 parts of epoxy resin, 22 parts, resol, 6 parts of gluey Graphite Powder 99s, 12 parts, stannic oxide, 9 parts of titanium dioxides, 14 parts of wilkinites, 7 parts of tripoly phosphate sodium STPPs and toluene.
Embodiment 3
A kind of electronic component protective membrane, wherein, protective membrane is made up of the component of following mass fraction: 12 parts, 60 parts of epoxy resin, 18 parts, resol, 5 parts of gluey Graphite Powder 99s, 7 parts, stannic oxide, 6 parts of titanium dioxides, 9 parts of wilkinites, 3 parts of polyacrylamides and acetone.
Below by specific experiment, further illustrate the excellent effect that the present invention reaches.
The protective membrane that above-mentioned embodiment is made is made model, is experimental group; Getting untreated electronic component is control group, tests, and result is as follows:
Radioprotective test: embodiment 1-3 radiation shielding rate is all higher than 90%, and control group is 53%;
Anti-electrostatic test: embodiment 1-3 is better than control group;
Weathering resistance test: embodiment 1-3 is better than control group.
Hence one can see that, and electronic component protective membrane provided by the invention has the performance of fine protection electronic component.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention.To be apparent for those skilled in the art to the multiple modification of these embodiment, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
