Description
Technical field
The utility model relates to a kind of protective membrane, relates in particular to a kind of hot soarfing from bi base material protective membrane.
Background technology
The material such as glass, plastic plate is in carrying and use procedure, and its surface is easily subject to contact stain(ing) or polishing scratch scratches, and makes it to avoid damage and pollutes so conventionally adopt protective membrane to cover its surface.In prior art, protective membrane used is substantially all planar protection film, and it comprises substrate layer, adhesive coating and release layer under normal circumstances.Described substrate layer is generally the materials such as poly-carbon polyester (PC), polyethylene (PE), PET, orientation stretching polypropylene (OPP) or aromatic polyester and forms, the primary structure layer that substrate layer is protective membrane; Adhesion laminating floats on a side of substrate layer, is conventionally made up of the institute such as polymkeric substance or acrylate copolymer of containing organoalkoxysilane, in order to substrate layer is posted up to the body surface of wish protection; And release layer is for the protection of the protective membrane under unused state, when use, release layer is removed and sticked to body surface.
This so common planar protection film forms by three layers, and along with the variation of other situation of humidity, temperature and surrounding environment, adhesive coating easily makes moist or is subject to chemical reaction and produces the phenomenon that substrate layer comes off; In the time that needs are changed or are processed original protective membrane, because being affixed on affixed object for a long time, adhesive coating there will be cull phenomenon, be difficult for processing.
Summary of the invention
The utility model provides a kind of hot soarfing from bi base material protective membrane, and this hot soarfing has good viscosity during from bi base material protective membrane low temperature, thereby adhesiveproperties disappears and effectively avoided damage and the cull to glass when high temperature.
For achieving the above object, the technical solution adopted in the utility model is: a kind of hot soarfing is from bi base material protective membrane, comprise the polyethylene base material film of the metal-coated layer of upper surface and the polypropylene base film of the metal-coated layer of lower surface, described polyethylene base material thin film metal layer and polypropylene base thin film metal layer are bonding by an adhesive-layer; Described polyethylene base material film lower surface has a pressure-sensitive adhesive layer, and another surface label of this pressure-sensitive adhesive layer is covered with separated type material layer; In described pressure-sensitive adhesive layer, be evenly distributed with several microspheres, the diameter of this microspheres is 3～18um.
In technique scheme, further improved technical scheme is as follows:
1,, in such scheme, the contact surface roughness of described pressure-sensitive adhesive layer and separated type material layer is 2. 821 microns～3. 324 microns.
2,, in such scheme, described separated type material layer is off-style paper layer or release film layer.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, the utility model hot soarfing is from bi base material protective membrane; in its pressure-sensitive adhesive layer, be evenly distributed with some microspheres; the diameter of this microspheres is 9～15um; make prepared pressure-sensitive adhesive tape when lower than 60 DEG C; there is good viscosity; toast after 5 minutes higher than 110 DEG C when temperature, this pressure sensitive adhesive loses adhesiveproperties.This pressure sensitive adhesive changes the viscosity size variation of sealing tape by temperature variation interval, possess splendid binding property and thermally strippable, has good application prospect at electronic unit manufacturing process, the aspect such as temporary fixed.
2, the utility model hot soarfing is from bi base material protective membrane, and the contact surface roughness of pressure-sensitive adhesive layer and separated type material layer is 2. 821 microns～3. 324 microns, the discharge of gas while being conducive to fit, thus avoid the generation of bubble.
