Abstract
The invention provides an adhesive resin composition and a self-adhesive protective film, wherein the adhesive resin composition comprises 5-20 parts by weight of a styrene block copolymer, 5-15 parts by weight of a tackifying resin and 100 parts by weight of a maleic anhydride grafted styrene block copolymer. The adhesive resin composition improves the compatibility of the styrene block copolymer and tackifying resin by introducing the maleic acid oversrafted styrene block copolymer, thereby obtaining the self-restorative prism sheet protective film with high initial adhesion and reducing surface pollution.
Description
Technical Field
The invention relates to the field of protective films, in particular to an adhesive resin composition and a self-adhesive protective film.
Background
For the prism sheet with high self-recovery, the protective film with low initial adhesion is easy to float after being attached. In addition, in the prism sheet manufacturing process, in order to detach the prism sheet from the mold, a stripper is usually added and transferred to the prism sheet, so that the surface tension of the prism sheet is high and the prism sheet is difficult to attach.
CN 103620450A proposes to improve the adhesion of the protective film by adding a terpene phenol resin which cannot be phenol content. The excessive addition of terpene phenolic resin is not mentioned to cause surface contamination of the prism sheet. The prism sheet protective film disclosed in CN 102292655A reduces unwinding, fails to significantly improve initial adhesion, and is not easy to attach to a self-restorative prism sheet. The invention disclosed in CN 104837946A is prepared into a PET base material protective film in a coating mode, and the influence of the addition amount of terpene phenolic resin on paste residue and surface pollution is specified. The protective film for a prism sheet proposed in CN 106459684A mainly solves the problem of end peeling, and fails to effectively improve the initial adhesion.
Therefore, it is necessary to provide an adhesive resin composition and a self-adhesive protective film to solve the problems of low initial adhesion of the protective film to the prism sheet and contamination of the protective film to the prism sheet in the prior art.

Detailed Description
The present invention will be described in detail with reference to embodiments. These embodiments are not intended to limit the invention and structural, methodological, or functional modifications of these embodiments that may be made by one of ordinary skill in the art are included within the scope of the invention.
As described in the prior art, the conventional protective film is attached to the prism sheet with low initial adhesion, and the protective film is easy to pollute the prism sheet. The present inventors have studied on the above problems and have proposed an adhesive resin composition comprising a styrene block copolymer, a tackifying resin and a maleic anhydride-grafted styrene block copolymer, wherein the tackifying resin is 5 to 20 parts by weight and the maleic anhydride-grafted styrene block copolymer is 5 to 15 parts by weight based on 100 parts by weight of the styrene block copolymer. When the adhesive resin composition with the proportion is used for a self-adhesive protective film, the adhesive resin composition has stronger adhesive force to a coated object, especially a prism sheet, and the adhesive force is more than or equal to 5g/25mm. At the same time, the adhesive resin composition is not easy to precipitate, and can not cause pollution on the surface of a coating object such as a prism sheet.
In the present invention, the above-mentioned styrene block copolymer is a copolymer of styrene and an olefin or a hydride thereof. For example, it may be one or more of a styrene-butadiene-styrene block copolymer, a styrene-isoprene-styrene block copolymer, a styrene-ethylene-butylene-styrene block copolymer, a styrene-ethylene-propylene-styrene block copolymer, or a hydride thereof.
In a preferred embodiment, the styrene block copolymer of the present invention is selected from one or more of the group consisting of a hydride of a styrene-butadiene-styrene block copolymer (SEBS) and a hydride of a styrene-isoprene-styrene block copolymer (SEPS).
For the self-restorative prism sheet, the protective film made of the styrene block copolymer is not satisfied with the bonding condition, and a sufficient amount of tackifying resin is required to be added. In the present invention, the tackifying resin composition comprises 5 to 20 parts by weight of the tackifying resin per 100 parts by weight of the styrene block copolymer, and if the tackifying resin is less than 5 parts by weight, the adhesive force of the adhesive layer is not changed even if the tackifying resin is compounded, and the desired adhesive force cannot be obtained; if the content of the tackifying resin exceeds 20 parts, there is a possibility that significant surface contamination may be brought about because of poor compatibility of the styrene block copolymer with the tackifying resin. Preferably, the tackifier resin is 10 to 20 parts.
The tackifying resin is one or more selected from petroleum resin, rosin resin and terpene phenolic resin.
In a preferred embodiment, the tackifying resin is selected from one or more of terpene phenolic resins such as UH115 of the Anyuan chemistry, S145 of the Anyuan chemistry, and the like. Since the terpene phenolic resin contains phenolic hydroxyl groups and has high polarity, the initial tackiness is excellent, but the presence of phenolic hydroxyl groups changes the compatibility of the tackifying resin with the styrene block copolymer, thereby causing surface contamination.
According to the invention, the maleic anhydride grafted styrene block copolymer is added, so that the compatibility of the styrene block copolymer and the terpene phenolic resin is improved, and the self-restorative prism sheet protective film with high initial adhesion is obtained. The maleic anhydride grafted styrene block copolymer is one or more selected from maleic anhydride grafted SEBS and maleic anhydride grafted SEPS.
In the invention, the grafting rate of the maleic anhydride in the maleic anhydride grafted styrene block copolymer is 0.5-2%. The maleic anhydride grafted styrene block copolymer with different grafting rates can improve the compatibility of the maleic anhydride grafted styrene block copolymer and the maleic anhydride grafted styrene block copolymer, and reduce the incidence rate of surface pollution. If the grafting ratio is less than 0.5%, the compatibility of the styrene block copolymer and the terpene phenolic resin cannot be effectively improved; if the grafting ratio is more than 2%, polymerization of the maleic anhydride-grafted styrene block copolymer is not facilitated.
In order to further improve the initial tackiness of the tacky resin composition and prevent the contamination thereof to a coating material, in a preferred embodiment of the present invention, the tacky resin composition further contains a phenoxy resin in an amount of 0.5 to 10 parts by weight based on 100 parts by weight of the styrene block copolymer, and if the phenoxy resin content is less than 0.5 parts by weight, no significant effect is exerted on the improvement of the initial tackiness; if the phenoxy resin content is more than 10 parts by weight, the adhesive resin composition becomes hard, and the improvement of the initial tackiness is also disadvantageous. Preferably, the phenoxy resin is 0.5 to 5 parts by weight.
The molecular weight of the phenoxy resin is 2 x 10 4 ～5*10 4 The phenoxy resin is used as a high-polarity macromolecular material and also contains hydroxyl or carboxyl, so that the polarity of the adhesive resin composition can be obviously improved, the overall viscosity is increased, and the interaction force with the prism sheet is enhanced.
The adhesive resin composition is prepared into adhesive layer master batch by a double-screw melting technology through an underwater pelletizing mode. The self-adhesive protective film is prepared by three layers of coextrusion of an adhesive layer, an intermediate layer and a surface layer.
The self-adhesive protective film has proper adhesive property even if the surface of the coated object is in a prism structure, the adhesive force between the self-adhesive protective film and the prism surface is more than or equal to 5g/25mm, and the self-adhesive protective film has no pollution to the prism sheet.
