Description
Technical field
The present invention relates to protection technical field of membrane, and in particular to a kind of protecting film convenient for winding.
Background technology
Thermoplastic polyurethane TPU elastomers are a kind of novel plastic foil kinds, it has excellent weatherability, environmental protection
Property, processability, elasticity, lustrous surface and touch comfort are applied to automobile adhesive film neck using it as the base material of gum product
In domain, good modification and defencive function can be played to automobile finish.Protecting film in application is used frequently as coiled material, is being wound
Shi Yinwei tension forces are improper or windup rate is too fast, can make occur bubble in wrapup procedure.Because this winding is tighter
It is real, and TPU has flexibility and elasticity, and so the place that bubble is heaved, TPU membrane remains such a shape heaved
State.To which TPU coiled materials are after unreeling expansion, and TPU is uneven, and the pit of bubble shape occurs in surface.
A kind of super body sticker is disclosed by the Chinese utility model patent 201621152509.9 of our company application, including super
Permeable layers, glue-line, adherent layer, it is characterised in that the super permeable layers are TPU membrane or PVC film, and the surface of the super permeable layers is contained
Bright hardening elastic coating, the glue-line are transparent pressure sensitive glue-line, and the adherent layer is wire drawing PET release films or frosted PET
Release film.The technical issues of wire drawing PET release films or frosted PET release films wherein with certain light transmittance solve is to replace passing
White silicon paper of uniting and covered selling point and body sticker is bonded bad problem.Also, super permeable layers and coating one thereon
As there is high gloss and high-transmittance, in winding due to winding more consolidation, rough release film and super permeable layers or painting
Layer compresses for a long time can substantially reduce its high photosensitiveness, therefore super permeable layers or coating can become crude, so glossiness can reduce, shadow
Ring product effect.

Wherein, the protective layer is Electrostatic Absorption film.
Wherein, the holding power of the mucigel is more than 48h, and for 24 hours, 180 ° of peeling forces are 4 ~ 11N/ to the mucigel
25mm。
The utility model has carried out the improvement in effect on traditional structure, uses special release film as anti-sticking
Layer, the Rough Horizontal Plane of release film is under.The wire drawing that adherent layer used in the utility model is preferably prepared using mechanical fiber elongation method
The frosted release film that release film, painting have been scraped the frosted release film of frosted coating or prepared using physical frosted method.Mechanical fiber elongation method
The wire drawing release film of preparation is marked without several outer wall concave lines using the means of machinery stroke silk to the non-layer upper surface of release film.Physics is ground
Sand method prepare frosted release film be to non-layer upper surface using physical means grind it is coarse, form countless pits.Frosted has been scraped in painting
The frosted release film of coating is that the coating for scraping out-of-flatness is applied to the non-layer upper surface of release film, forms countless pits.Because of its lower surface
It is rough, gas can be discharged from outer wall concave line or pit after making winding, to keep the protecting film after winding more smooth, and
And it can also keep smooth after unreeling expansion.
Wherein PC release films have higher intensity and coefficient of elasticity, and dimensionally stable, creep are small, are used for protecting film
Coiled material, which uses, has better mechanical property, also preferably.
Protecting film described in the utility model further includes layer protective layer, and the film with low viscous adhesive, bilayer can be used altogether
Extruded film or Electrostatic Absorption film are used for barrier coat and the adherent layer with Rough Horizontal Plane, are close to rear Rough Horizontal Plane pair for protecting
