By using above-mentioned technical proposal, a kind of high temperature resistant protective film disclosed in this programme mainly includes substrate, propylene
Sour pressure sensitive adhesive, release film, substrate are connected by acrylate pressure sensitive adhesive with release film;When needing to carry out to screen or electronic component
When protection, directly substrate is stripped, is contacted by acrylate pressure sensitive adhesive with screen or electronic component;Substrate is resistance to height
Warm lower shrinkage substrate, and acrylate pressure sensitive adhesive mainly includes acrylic copolymer, ethyl acetate, curing agent, high temperature resistant filling
Agent and low precipitation auxiliary agent since low precipitation auxiliary agent surface can be lower, thus have good high temperature resistance, are conforming to glass
After upper, it is resistant to 220 DEG C of high temperature in vacuum environment, will not occur the situations such as heaving, wrinkle, there will not be after opening white
Mist or residue glue occur, thus can be widely used in the technique of various high temperature resistant protections.
Preferably, each content of material in acrylate pressure sensitive adhesive is based on component:
Preferably, the substrate layer is high temperature resistant lower shrinkage substrate, the high temperature resistant lower shrinkage substrate uses high temperature resistant
PET, PI and PEN.
Preferably, the crosslinking agent is thermal cross-linking agent.
Preferably, the crosslinking agent is using amine, epoxies, isocyanates and metallic salt etc..
Preferably, the high temperature resistant filler uses containing benzene ring substance, polyimides substance or contains conjugated bonds
Class chemical substance.
Preferably, the weight average molecular weight of the acrylic copolymer is 100,000 or more, 1,000,000 or less.
Preferably, the low precipitation auxiliary agent is low-surface energy substance, the low molecular weight that auxiliary agent is precipitated is 5000-
60000。
The object of the present invention is to provide a kind of low precipitation protective films of high temperature resistant.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of low precipitation protection of high temperature resistant
Application of the film on electronic device touch screen.
In conclusion the invention has the following advantages:
1. a kind of high temperature resistant protective film disclosed in this programme mainly includes substrate, acrylate pressure sensitive adhesive, release film, base
Material is connected by acrylate pressure sensitive adhesive with release film;When needing to protect screen or electronic component, directly by substrate
It strips, is contacted by acrylate pressure sensitive adhesive with screen or electronic component;Substrate is high temperature resistant lower shrinkage substrate, and third
Olefin(e) acid pressure sensitive adhesive mainly includes acrylic copolymer, ethyl acetate, curing agent, high temperature resistant filler and low precipitation auxiliary agent, by
Can be lower in low precipitation auxiliary agent surface, thus there is good high temperature resistance, after conforming on glass, in vacuum environment
In be resistant to 220 DEG C of high temperature, will not occur the situations such as heaving, wrinkle, there will not be white haze or residue glue after opening and occur, thus energy
It is widely used in the technique of various high temperature resistant protections;
2. the research about such adhesive tape is more since such adhesive tape use scope is wide;Such as application No. is
A kind of high temperature resistant protective film disclosed in the Chinese patent of " 201510843404.1 ", the high temperature resistant protective film in the program, though
So there is good viscosity, adhesion strength and spin initial bonding strength, but its mesoglea only can be long-term in the environment of -20 DEG C -120 DEG C
It keeps its performance constant, is not in the deformation such as warpage, heatproof is up to 180 DEG C in the short time;Other similar protection on the market
Film, heatproof degree is similar therewith, and temperature tolerance of the invention may be up to 220 DEG C, or even when slightly above 220 DEG C, still
With good stability.
Specific embodiment
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
Embodiment:
A kind of low precipitation protective film of high temperature resistant, from top to bottom successively includes release layer, adhesive layer and substrate layer, and adhesive layer is
Acrylate pressure sensitive adhesive, acrylate pressure sensitive adhesive mainly include acrylic copolymer, ethyl acetate, curing agent, high temperature resistant filler,
Low precipitation auxiliary agent.
Each material composition is identical in embodiment 1- embodiment 5, but a content of material is different, is detailed in shown in the following table 1, test wrapper
Border is resistance to 250 DEG C of 10min under vacuum condition,.
Table 1:
Each material composition and its test result in embodiment 6- embodiment 9 and comparative example, are detailed in shown in the following table 2;
Table 2:
△ representative has residue glue, and zero representative has white haze, and X representative has residue glue and white haze, and OK is represented without white haze and residue glue, and is represented
Fold with heave
Only change the low amount that auxiliary agent is precipitated in embodiment 1, embodiment 2 and embodiment 3, other are remained unchanged, and verify low analysis
Influence of the amount of auxiliary agent to white haze residue glue, Tai Shaoshi out do not have effect, so having white haze, can be precipitated when too many, float on by
Object surface is pasted, also will form white haze;
The amount of embodiment 2, embodiment 4 and embodiment 5 change high temperature resistant fillers, other are remained unchanged, and verify resistance to height
Influence of the amount of warm filler to white haze residue glue, Tai Shaoshi do not have effect, so having residue glue, can be precipitated, float on when too many
Affixed object surface, will form white haze;
Only change the amount of crosslinking agent in embodiment 2, embodiment 6 and embodiment 7, other are remained unchanged, and verify crosslinking agent
The influence to white haze residue glue is measured, Tai Shaoshi, crosslink density is low, and molecular weight is small, so being easy residue glue, can be precipitated when too many, small point
Son floats on affixed object surface, will form white haze;
Only change the type of substrate in embodiment 2, embodiment 8, embodiment 9 and comparative example, other are remained unchanged, and verifying is not
With the substrate influence apparent to white haze residue glue and protective film, the results showed that the white haze residue glue of common PET and apparent all bad,
Because the heat-resisting quantity of common PET is bad, has substance and be precipitated or decompose, therefore can deform and generate white haze residue glue.
In summary the performance of basement membrane and curing agent and heatproof auxiliary agent and it is low be precipitated auxiliary agent to the white haze of heatproof protective film and
The performances such as residue glue have an impact.
