Description
Technical field
The present invention relates to protection technical field of membrane, more particularly, to a kind of UV visbreakings composition, UV dehesions film and its preparation
Method.
Background technology
In semiconductor process, when carrying out semiconductor crystal wafer cutting, polishing, to reduce silicon thin layer defect concentration, often
It is often used wafer cutting visbreaking protective film.Visbreaking protective film refers to that bonding force is strong when in use, and in later stage stripping process, it glues
Resultant force weakens to remove.
Visbreaking protective film currently on the market is mostly UV visbreaking protective films, refers to having high adhesion power in UV pre-irradiations,
Adhesion is good, and bonding force is decreased obviously after UV irradiations, is easily peeled off.Cut for wafer on domestic market and pick technique etc.
The UV visbreakings glue of protection is mostly based on Japan, TaiWan, China, and domestic UV visbreakings glue is also several to be promoted in research and development, but performance is not yet
Complete stability.Also, the base material of UV visbreaking protective films in use due to rubbing action be easy to generate electrostatic, for
The use in the more demanding electronic component field of electrostatic is restricted, for example is easy absorption dust, is then transferred into the production of fitting
Product surface or electrostatic potential are excessively high, cause part to generate bad etc..In addition, current visbreaking protective film is after applied at elevated temperature,
Residue glue is be easy to cause to be not easy to remove.
In view of this, special propose the present invention.
Invention content
The first object of the present invention is to provide a kind of UV visbreakings composition have excellent peeling force in UV pre-irradiations,
Peeling force, which declines to a great extent, after UV irradiations is easily peeled off, and has excellent anti-static electrification, and can be resistant to 120 DEG C of high temperature
30 minutes not residue glues.
The second object of the present invention is to provide a kind of UV visbreakings film, and the UV visbreakings film has excellent in UV pre-irradiations
Peeling force, peeling force, which declines to a great extent, after UV irradiations is easily peeled off, and has excellent anti-static electrification, can be resistant to 120 DEG C
The not residue glue of high temperature 30 minutes.
Another object of the present invention is to provide a kind of preparation method of the UV visbreakings film, the preparation method operative employees
Skill is simple, favorable repeatability.
In order to realize that the above-mentioned purpose of the present invention, spy use following technical scheme：
A kind of UV visbreakings composition, is mainly made of the following raw material by weight percentage：
High temperature resistant acrylate pressure-sensitive adhesive resin 20%-50%, polyfunctionality oligomer and/or polyfunctional monomer 1%-
30%, crosslinking agent 0.3%-2%, antistatic agent 0.1%-5%, dispersant 0-2%, levelling agent 0.2%-2%, photoinitiator
0.5%-5% and solvent 25%-60%.
Wherein, the high temperature resistant acrylic pressure sensitive gum resin cohesive force is high, is resistant to 120 DEG C of hot conditions, and
30min not residue glues, so as to improve the residue glue situation of the UV visbreakings composition.
Preferably, the high temperature resistant acrylate pressure-sensitive adhesive resin is solvent-type acrylic ester pressure-sensitive adhesive.More preferably

The UV visbreaking compositions that the present invention is prepared by above-mentioned raw materials have excellent bonding force, UV pre-irradiations tool
There is high adhesion, peeling force is high, has low adhesion power after UV irradiations, UV peeling forces are low, and antistatic effect is good, can be resistant to 120 DEG C
High temperature not residue glue.The polyfunctionality oligomer and/or polyfunctional monomer itself generate cross-linking reaction, crosslinking after UV irradiates
Larger volume contraction is generated after reaction makes to generate fold between the UV visbreakings composition and adherend body surface face, and fold is big
Position generates micropore, and contact area between UV visbreakings composition and adherend body surface face is made to reduce, to realize that visbreaking acts on.
Acrylate pressure-sensitive adhesive resin, under smaller active force, you can firm bonding force is formed, without other
Means can be closely bonded with adherend.Conventional acrylic ester pressure-sensitive resin, though have many advantages, such as that initial bonding strength is big, due to
Its architectural characteristic, heat resistance is poor, easily softens under high temperature and loses cementability, and hot conditions use appearance after substrate surface fitting
