Description

Interleaving paper or silicone composition for release film, interleaving paper and stripping film

Technical field

The present invention relates to the silicon composition for suppressing the manufacture of the effect of the phenomenon of re-separation (hereinafter referred to as resistance to exposed property) is excellent owing to exposing in an atmosphere interleaving paper and stripping film to be applicable to, also can maintain the silicon composition of good peel property even if the coated face of the silicone release paper related to by said composition coating being manufactured and stripping film is subject to atmospheric exposure and defines the interleaving paper of solidification tunicle and the stripping film of said composition.

Background technology

Stripping film, interleaving paper are the surface coated silicon-type strippers at the base material such as plastic film, paper, form solidification tunicle, use widely as the stripper tunicle for cementability and even adhesive by crosslinking reaction.

As such curable organopolysiloxane composition, known using the organopolysiloxane containing vinyl with have with the organic hydrogen polysiloxanes of the hydrogen atom of silicon atom bonding as principal constituent, the stripping composition of addition reaction curing that makes it solidify by hydrosilylation reactions, due to have curing speed fast, peel property can be made to carry out the advantages such as various changes, therefore use widely as stripping composition.But, for the stripping composition of addition reaction curing, indicate following phenomenon: if the tunicle making solidification and obtain is exposed to the outside gas, then peeling force increases the weight of singularly, sometimes become and can not peel off.Therefore, interleaving paper, the stripping film of stripper tunicle is defined at the stripping composition of use addition reaction curing, manufacture in the process of label, adhesion zone class, if make silicone coated tunicle be exposed to air, then can not maintain the separability needed for these goods, cause stripping bad, cause the serious decline of quality.

In order to solve this problem, reporting and in the stripping composition of addition reaction curing, coordinating the method for alcohol modified organopolysiloxane, polyether-modified organopolysiloxane (JP 55-3460 publication: patent documentation 1) and coordinate a method (Unexamined Patent 1-217068 publication: patent documentation 2) only at the Siliciumatom of single end with the organic hydrogen polysiloxanes of hydrosilyl as a part for organic hydrogen polysiloxanes.But, although these methods confirm to suppress owing to exposing and the effect of the phenomenon of re-separation in an atmosphere, and not enough.Also there is the weakness that the residual bonding force of bond layer is reduced.

In patent No. 2934118 publication (patent documentation 3), show the method for structure limiting linking agent, although improve the decline of residual bonding force, peeling force to increase the weight of etc. large on the impact of other peel property.

Summary of the invention

The problem that invention will solve

The present invention completes in view of above-mentioned practical situation, object be to provide suppress stripper transport property, detrimentally affect, the interleaving paper with the addition reaction curing of the stripper tunicle of resistance to exposed property or silicone composition for release film are not produced to residual bonding force, peeling force, and define the interleaving paper of solidification tunicle and the stripping film of said composition.

For solving the means of problem

The present inventor furthers investigate to achieve these goals and repeatedly, found that: be selected from alkene and the diolefine at end with unsaturated link(age) by coordinating in the silicon composition of addition reaction curing, there is the specified quantitative at end with the compound of more than a kind in the silane of the thiazolinyl of unsaturated link(age) and sily oxide, thus the transport property of the stripper that is inhibited, not to residual bonding force, peeling force produces detrimentally affect, there is interleaving paper or the silicone composition for release film of the stripper tunicle of resistance to exposed property, define the interleaving paper of the solidification tunicle of said composition and the resistance to exposed property of stripping film and separability excellent, even if the solidification tunicle that this interleaving paper and stripping film are formed is exposed to air for a long time, also the separability before exposure can substantially be maintained, complete the present invention.

[peeling force]

Peeling agent layer is formed in the same manner as above-mentioned solidified nature evaluation, wide 50mm polyester adhesion zone (ニットー 31B, day east electrician's (strain) trade(brand)name processed) is placed on the surface of peeling agent layer, next, this adhesion zone places 1, the load of 976Pa, heat treated 20 hours at 70 DEG C, fits polyester adhesion zone and peeling agent layer.Then, use tensile testing machine, from peeling agent layer, polyester adhesion zone is peeled off (peeling rate 0.3m/ divides) with the angle of 180 ゜, measure peeling force.

[residual bonding rate]

In the same manner as the mensuration of above-mentioned peeling force, polyester adhesion zone and peeling agent layer are fitted.Then, from peeling agent layer, polyester adhesion zone is peeled off, this polyester adhesion zone is pasted on stainless steel plate.Next, use tensile testing machine, from stainless steel plate, polyester adhesion zone is peeled off, measure peeling force X.
