Abstract

The invention discloses a silicon oil isolating film for pressure sensitive adhesive tape. The film is characterized by comprising a polyester film layer and a coating laminated on the polyester film layer. The surface of the laminated coating not in contact with the polyester film layer is embossed with a graphic area of which the surface is coated with an organic parting agent layer. The laminated coating comprises, by weight, high density polyethylene, low density polyethylene, styrene-isoprene-styrene block copolymers SIS, styrene and butadiene block copolymers SBS, paraffins, glycerine, POE polyolefin elastomer and coupling agent. The net shaped vein created on the film forms an explicit embossed graphic. The depth of the graphic vein is consistent, and the distribution lines are also uniformly spread.

Description

Silicone oil isolating membrane for pressure sensitive adhesive tape
Technical field
The present invention relates to a kind of silicone oil isolating membrane for pressure sensitive adhesive tape, belong to separated type material technical field.
Background technology
Generally mould release membrance refers to be coated with organic silicone oil in polyester film surface, plays antiseized effect；Mould release membrance surface can To have bright finish and mute face, but when the pressure sensitive adhesive adhesive tape of this traditional release film production and label tape, glue surface landscaping effect is not Ideal, when common mould release membrance and pressure sensitive adhesive adhesive tape gluing, easily produces bubble between the two.Using embossing release paper although The effect of aerofluxuss bubble can be reached, but easily absorbed water due to release paper, tearing toughness not high, be difficult to observe glue surface, cross cutting Afterwards, there is paper scrap at edge it is impossible to be used by high-end product.
Content of the invention
It is an object of the present invention to provide a kind of silicone oil isolating membrane for pressure sensitive adhesive tape, this is used for the silicone oil isolation of pressure sensitive adhesive tape Its netted lines embossing of being formed of film is clear, depth unification, distributing line uniformly, the embossing laminating release film of formation with pressure sensitive adhesive Bubble will not be produced between the two, thus not having influence on using effect during laminating.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of silicone oil isolating membrane for pressure sensitive adhesive tape, bag Include laminated polyester film and and be coated on the film coat of mylar layer surface, this film coat is opposite with laminated polyester film Surface there is pattern of indentations area, the surface in this pattern of indentations area is coated with a silicone release oxidant layer, described film coat by The group of following weight portion is grouped into: 100 parts of high density polyethylene (HDPE), 150 parts of Low Density Polyethylene, styrene-isoprene-benzene second Block copolymer sbs15 part of alkene block copolymer sis26 part, styrene and butadiene；
0.5 ~ 1.5 part of paraffin,
0.1 ~ 0.5 part of glycerol,
5 ~ 10 parts of poe polyolefin elastomer,
0.3 ~ 0.8 part of coupling agent；
Described poe polyolefin elastomer is the high polymer of ethylene and butylene；
The ratio of the block copolymer of described styrene isoprene styrene block copolymer (SIS) and styrene and butadiene is 2:0.9.
In technique scheme, further improved scheme is as follows:
In such scheme, described coupling agent is silane coupler.
Because technique scheme is used, the present invention compared with prior art has following advantages and an effect:
The present invention is used for the silicone oil isolating membrane of pressure sensitive adhesive tape, and the netted lines embossing that it forms is clear, depth unification, and distributing line is equal Even, the embossing laminating release paper of formation will not produce bubble when with pressure-sensitive glue laminating between the two, thus not have influence on making Use effect；Secondly, it adds 10 parts ~ 30 parts of styrene isoprene styrene block copolymer (SIS), styrene and butadiene 5 parts ~ 15 parts of block copolymer and 5 ~ 10 parts of poe polyolefin elastomer are so that the cohesive force of parting agent layer and mylar interlayer Even closer, and substantially improve remnants then rate, release layer is difficult for drop-off, and mesh further improves the antistatic performance of film.
Specific embodiment
With reference to embodiment, the invention will be further described:
Embodiment: a kind of silicone oil isolating membrane for pressure sensitive adhesive tape, including laminated polyester film and and be coated on laminated polyester film table The film coat in face, this film coat surface opposite with laminated polyester film has pattern of indentations area, this pattern of indentations area Surface be coated with a silicone release oxidant layer, described film coat is grouped into by the group of following weight portion:
Table 1
Above-mentioned poe polyolefin elastomer, embodiment 1 is the high polymer of ethylene and octene, and embodiment 2 is gathered for the height of ethylene and octene Thing, embodiment 2 is the high polymer of ethylene and butylene, and embodiment 2 is the high polymer of ethylene and butylene, and embodiment 2 is ethylene and pungent The high polymer of alkene.
The ratio of above-mentioned styrene isoprene styrene block copolymer (SIS) and styrene and the block copolymer of butadiene Example is: embodiment 1 is 2:1, embodiment 2 is 2:1.05, embodiment 3 is 2:0.9, embodiment 4 is 2:1, embodiment 4 is 2: 0.95.
Above-mentioned laminated polyester film is one of pp, pet, pbt, pen and pbn.
Comparative example 1: a kind of silicone oil isolating membrane for pressure sensitive adhesive tape, including laminated polyester film and and be coated on mylar The film coat of layer surface, this film coat surface opposite with laminated polyester film has pattern of indentations area, this embossing figure The surface in case area is coated with a silicone release oxidant layer, and described film coat is grouped into by the group of following weight portion: high density is gathered 100 parts of ethylene, 125 parts of Low Density Polyethylene.
Comparative example 2: a kind of silicone oil isolating membrane for pressure sensitive adhesive tape, including laminated polyester film and and be coated on mylar The film coat of layer surface, this film coat surface opposite with laminated polyester film has pattern of indentations area, this embossing figure The surface in case area is coated with a silicone release oxidant layer, and described film coat is grouped into by the group of following weight portion: high density is gathered 100 parts of ethylene, 150 parts of Low Density Polyethylene.
The silicone oil isolating membrane for pressure sensitive adhesive tape of embodiment 1 ~ 5 and comparative example gained is tested, as shown in table 2:
Table 2
During using the above-mentioned silicone oil isolating membrane for pressure sensitive adhesive tape, the netted lines embossing that it forms is clear, depth unification, distribution Uniformly, the embossing laminating release film of formation will not produce bubble when with pressure-sensitive glue laminating to line between the two, thus not impact To using effect；Secondly, it adds 10 parts ~ 30 parts of styrene isoprene styrene block copolymer (SIS), styrene and fourth two 5 parts ~ 15 parts of the block copolymer of alkene and 5 ~ 10 parts of poe polyolefin elastomer, coupling agent 0.3-0.8 part is so that film coat Even closer with the cohesive force of mylar interlayer, and substantially improve remnants then rate, release layer is difficult for drop-off, and mesh also changes It has been apt to the antistatic performance of film.
