Also that is, common UV glue, lattice solidification are irreversible, UV glue and the close leaching of glued body surface generation
Profit, after ultraviolet light, forms firm lattice structure with glued surface, which can not be soft by heating
Change recrystallization, it can only be disposable.This feature of common UV glue causes to be difficult dismantling stripping by the object of UV glue sticking
From doing over again or repair very difficult.However, exactly this feature is also that this application provides additional advantages.
For example, in the prior art there is also it is a kind of can hot melt adhesion repeatedly substance, can be glued by way of heating
It connects, removing can also be disassembled by way of heating.But when this substance is applied on electronic equipment, due to electricity
Sub- equipment intermittence can occur during generating heat and cooling down in use, thus in certain close heat sources (such as CPU)
Position will appear part repeatedly be bonded and remove trend, be easy occur degumming phenomenon in use, switching performance is simultaneously
It is unreliable.Also, since this substance is hot melt adhesion, viscosity increases after heating, after the separation of glued object, meeting
Leave a large amount of residue glue on glued surface, generally require etc. it is to be cooled after strike off or be wiped repeatedly removing using solvent,
It operates also labor intensive, the efficiency done over again or repaired is not also high.
And the UV adhesive of the application, it is that the ethene-vinyl acetate copolymerization for accounting for gross mass 30-40% is added in UV glue
Object, by being sufficiently mixed, UV glue composition is solidified the two by ultraviolet light, while assisting 60-70 degrees Celsius of hot melt solidification process,
UV glue composition and ethylene-vinyl acetate copolymer together form firm bonded structure.When needing to disassemble, although UV
Lattice intensity after adhesive curing is very high, can not heat removing, but is had by the cured ethylene-vinyl acetate copolymer of lattice excellent
Different hot molten characteristic, when 100-110 degrees Celsius, the volume expansion of ethylene-vinyl acetate copolymer can destroy UV glue at
The lattice structure of part, leads to UV glue composition adhesive failure.The ethylene-vinyl acetate copolymer for breaking through lattice limitation is in molten state,
It is easy to from glued body surface disposably strip down entire glue-line, hardly leaves what residue glue, operation is very
It is easy.
On the other hand, when temperature is lower than 100-110 degrees Celsius of exfoliation temperature, the lattice structure meeting of UV glue composition
Ethylene-vinyl acetate copolymer is lockked, in the case where lattice is not destroyed, the UV adhesive of the application can't be lost
Effect, it is ensured that will not occur the phenomenon that degumming on an electronic device, adhesive property is very reliable.
Moreover, the UV adhesive of the application is when dismantling, UV glue composition therein is still in solid-state, although ethylene-
Acetate ethylene copolymer is in molten state, but since UV glue composition blendes together one therewith so that whole glue-lines form one it is whole
Body can integrally strip down, residue glue is seldom, non-quickly as the pieces of cloth soaked from the surface of glued object
Often it is easy to subsequent operation, substantially increases and do over again and maintenance efficiency.Also, due to the UV glue composition in the UV adhesive of the application
Irreversible feature after solidification causes the application in the ethyl vinyl acetate second after heating strip operation, largely lockked
Alkene copolymer ratio very little shared by glued surface, bonding force is not strong, when temperature be reduced to 75 degree hereinafter, again solidify after
Ethylene-vinyl acetate copolymer and the UV glue composition of failure form entirety, can be easy to entire glue-line from glued table
Face removing, and be stripped surface and will not leave any residue glue, perfect peeling effect can be obtained.Also that is, the application's
In one specific embodiment, preferably after being heated to 100-110 degrees Celsius of separated glued object, make UV adhesive glue-line
75 degrees Celsius are cooled to hereinafter, the glue-line is completely exfoliated from glued body surface.
