Description

Adhesive Tape for Surface Protection {ADHESIVE TAPE FOR SURFACE PROTECTION}

The present invention relates to an adhesive tape for surface protection, and more particularly, in an adhesive tape for surface protection in which an adhesive layer and a release treatment layer are laminated on one surface of a polyolefin film base layer, the release treatment layer is an acrylate-silicone. The present invention relates to an adhesive tape for surface protection, which is an adhesive comprising a copolymer, a curing agent, and a catalyst.

Steel sheet or glass for home appliances such as liquid crystal display (LCD), plasma display (PDP), organic EL (electroluminescence), field emission display, optical film (optical sheet), mobile, refrigerator, washing machine, air conditioner, etc. Various materials and the like are treated, and various surface treatments are performed for wear resistance, chemical resistance, scratch resistance, and the like of the finished product. However, since these parts are not free from defects such as foreign materials, scratches, and stamps during transportation from the material manufacturer, the surface protection film is usually attached to the parts and the product surface and prevents expensive product damage.

Since the adhesive tape for surface protection is directly in contact with the component material and the finished product, there should be no contamination of the surface of the adherend, and since the peeling property should be good after use, it becomes an important material in the adhesive tape. However, in order to lower the price, the adhesive tape is usually formed in one piece in which the adhesive layer enters the back treatment layer except that the release film enters the adhesive face of the adhesive tape.

In this case, if the adhesive tape is high peeled from the back of the magnetic layer, it is difficult to rewind, so that when the adhesive tape is attached to the adherend, there is a lot of noise or a defect that the adhesive tape is stretched. However, the release coating layer used for low peeling has caused a problem of causing contamination of the final adherend since the low molecular material is transferred to the pressure-sensitive adhesive layer. Therefore, the reliability of the characteristics of the back coating layer or the back release layer in addition to the pressure-sensitive adhesive layer has become important.

In Japanese Patent Laid-Open No. 2000-026814, the peeling force was reduced by using a silicone resin in which curing was caused by radiation in order to improve rewinding. However, this technique has a problem that a defect that causes contamination of the adhesive and the adherend occurs due to the generation of low molecular weight of the silicon-based. Therefore, in order to suppress the generation of low molecules, the curing at high temperature should be performed, but in the case of the surface protective adhesive tape, since the non-stretched polyolefin film having a low melting point is used, the film shrinks when curing at high temperature. In order to increase or increase the curing temperature or time, a stretched polyolefin film may be used, but the film is hardened in the drawing process, so that the film is vulnerable to being pressed or pressed.

In Japanese Patent Laid-Open No. 2006-036882, excellent rewindability is ensured by using a reaction product of a polyvinyl polymer containing an active hydroxyl group and a cyclic alkylisocyanate compound in the back treatment layer of the base layer. In practice, however, over time, the tape of this combination has a problem that the rewinding force is increased and the workability of the paste is bad.

In Korean Patent Laid-Open Publication No. 2008-0039292, in order to solve the above problem, an acrylic silicon graft polymer is used to lower surface energy and peel force and to secure reliability. However, the peeling force should be maintained when measuring the residual peeling force to determine whether the transfer of silicon or other low molecular weight material of the release layer occurs, but the peeling force may be reduced. In addition, there is a limit in increasing hardening and increasing reliability of the back release layer because of limitations in increasing or increasing the temperature or time of hardening.

On the other hand, in the conventional silicon-based release layer there is an additional problem that the release agent is dropped toward the pressure-sensitive adhesive layer due to the influence of humidity. In addition, in the manufacture of a silicon-based release treatment layer, a platinum-based catalyst may be used to lower the curing temperature. However, even if the temperature is lowered, it is difficult to secure reliability at 100 degrees or less.

Therefore, the present inventors confirmed that when the acrylate-silicone copolymer is used as one component of the adhesive in the surface protective adhesive tape of the present invention, it is possible to form a release layer even at low temperature, but also to produce an adhesive tape showing excellent peeling force. The present invention has been completed.

An object of the present invention is to provide a release treatment layer comprising an acrylate-silicone copolymer, a curing agent and a catalyst on one side of the polyolefin film base layer, not only excellent in initial peeling strength, time-lapse peeling and residual peeling strength, but also reflection appearance It is to provide a pressure-sensitive adhesive tape for excellent surface protection.

The surface protection adhesive tape of the present invention for achieving the above object is a pressure-sensitive adhesive layer on one surface of the polyolefin film base layer, a release treatment layer is laminated on the other surface, the release treatment layer is an acrylate-silicon air It is a pressure-sensitive adhesive comprising a coalescence, a curing agent and a catalyst.

The acrylate-silicone copolymer 40 to 90% by weight of the acrylate monomer; 10 to 40% by weight of an acrylic monomer having a siloxane group; And it is preferable that it is a copolymer obtained by superposing | polymerizing 3-15 weight% of monomers containing a crosslinkable functional group.

It is preferable that the acrylate monomer of the said acrylate-silicon copolymer is (meth) acrylate which has a C1-C12 alkyl group.

It is preferable that the acryl monomer which has the said siloxane group is a compound represented by following formula (1).

[Formula 1]

Wherein R ₁ is hydrogen or an alkyl group having 1 to 2 carbon atoms; R ₂ is an alkyl group having 1 to 10 carbon atoms; m and n are the integers of 1-10, respectively.

The monomer containing the crosslinkable functional group is preferably an acrylate monomer having at least one functional group selected from the group consisting of a hydroxyl group, a carboxyl group, an epoxy group, a vinyl group and an amide group.

The curing agent is preferably at least 0.5 to 10 parts by weight of at least one selected from the group consisting of an isocyanate compound, an epoxy compound, a melamine resin and an aziridine compound with respect to 100 parts by weight of the acrylate-silicon copolymer.

The catalyst is preferably one or more of 0.01 to 3 parts by weight based on 100 parts by weight of the acrylate-silicon copolymer from the group consisting of amine compounds, tin compounds and non-tin compounds.

Although the adhesive tape for protecting the surface of the present invention is manufactured by release treatment at a low temperature, not only the initial peeling force, the aging peeling force and the residual peeling force are excellent, but also excellent reflection appearance characteristics. As a result, a highly reliable surface protective adhesive tape excellent in rewinding property without falling off to the pressure-sensitive adhesive layer while maintaining low peeling on the magnetic back can be produced.

The surface protection adhesive tape of the present invention is a surface protection adhesive tape in which an adhesive layer and a release treatment layer are laminated on one surface of a polyolefin film base layer, wherein the release treatment layer comprises an acrylate-silicone copolymer, a curing agent and a catalyst. It is characterized by being an adhesive containing.

The acrylate-silicone copolymer allows the curing at low temperatures while introducing the existing silicone release agent to be cured at a high temperature to acryl, and as a result, it is possible to increase the reliability of the coating on the low-strength unstretched polyolefin film. . The acrylate-silicone copolymer for this purpose comprises 40 to 90% by weight of acrylate monomer (A); 10 to 40% by weight of the acrylate monomer having a siloxane group; And it is preferable that it is a copolymer obtained by superposing | polymerizing; 3-15 weight% (C) of monomer containing a crosslinkable functional group.

As the first component constituting the acrylate-silicon copolymer, the acrylate monomer (A) functions to lower the curing temperature of the release treatment layer. In general, a release treatment layer composed of a silicon component is difficult to manufacture when the temperature of the processing coating is less than 100 degrees even using a platinum catalyst or the like. Even if the silicon release treatment layer is manufactured at less than 100 degrees, the reliability is lowered, and thus, the release treatment layer is difficult to be used as the release treatment layer such that a large amount of transfer of the silicon component to the pressure-sensitive adhesive layer occurs and the peeling force is increased. The monomer is not particularly limited as long as it is a monomer usually used as an acrylic pressure-sensitive adhesive, and any of aliphatic acrylate, aliphatic methacrylate, cycloaliphatic acrylate, cycloaliphatic methacrylate and the like can be used. Hereinafter, including 'acrylate' and 'methacrylate' is referred to as '(meth) acrylate'. Among the acrylates, a (meth) acrylate monomer having an alkyl group having 1 to 12 carbon atoms is preferable. When the (meth) acrylate monomer having an alkyl group having 13 or more carbon atoms is used, the glass transition temperature of the monomer is low, making it difficult to polymerize into a desired copolymer. For example, methyl (meth) acrylate, ethyl (meth) acrylate, n-propyl (meth) acrylate, isopropyl (meth) acrylate, n-butyl (meth) acrylate, t-butyl (meth) Acrylate, sec-butyl (meth) acrylate, pentyl (meth) acrylate, 2-ethylbutyl (meth) acrylate, 2-ethylhexyl (meth) acrylate, n-octyl (meth) acrylate, isooctyl (Meth) acrylate, isononyl (meth) acrylate, etc. are mentioned. These may be used alone or in combination of two or more thereof.

On the other hand, the content of the acrylate monomer constituting the acrylate-silicone copolymer is preferably 45 to 87% by weight of the total weight of the acrylate-silicone copolymer. If the content of the acrylate monomer does not reach 45%, the polymerization is difficult because the content of the acrylate monomer having a siloxane group is relatively increased, and if the content of the acrylate monomer exceeds 87%, the releasing properties of the acrylate monomer are reduced. Cannot be represented.

It is preferable that the acrylate monomer (B) having the siloxane group as the second component constituting the acrylate-silicone copolymer is a compound represented by the following Chemical Formula 1:

Wherein R ₁ is hydrogen (H) or an alkyl group having 1 to 2 carbon atoms; R ₂ is an alkyl group having 1 to 10 carbon atoms; m and n are the integers of 1-10, respectively.

The acrylate monomer having a siloxane group of the above formula is prepared using a compound having a siloxane group and a diol containing R ₂ to produce a siloxane intermediate compound represented by the following Formula 2 to be grafted onto the acrylate while having a release property in a release treatment layer. To help you:

The diol containing R ₂ is methanediol, ethanediol, (iso) propanediol, (iso) butanediol, (iso) pentanediol, (iso) hexanediol, (iso) heptanediol, (iso) octanediol, ( It is preferably at least one diol selected from the group consisting of iso) nonnatatandiol and (iso) decanediol.

Since the siloxane intermediate compound of Formula 2 cannot form a acrylate-siloxane copolymer, it is incompatible with other acrylate monomers and thus cannot stably bring a chemical reaction, thereby using acryloyl chloride containing R ₁ . An acrylate monomer having a siloxane group is synthesized.

The acryloyl chloride comprising R ₁ is preferably at least one selected from the group consisting of acrylo chloride, methacryloyl chloride and etaacryloyl chloride.

The amount of the acrylate monomer having the siloxane group is preferably 10 to 40% by weight of the total weight of the acrylate-silicon copolymer. If the content is less than 10% by weight, the surface energy of the substrate is hardly reduced after coating on the substrate, and thus has low peeling characteristics. When the content is more than 40% by weight, steric hindrance occurs due to the bulk characteristics of the siloxane group to form polymerization. Becomes difficult.

As a third component constituting the acrylate-silicone copolymer, the monomer (C) containing the crosslinkable functional group forms a copolymer like the acrylate monomer and the acrylate monomer having the siloxane group to form a crosslinking reaction with a curing agent. To increase the durability. For this purpose, acrylate monomers having at least one functional group selected from the group consisting of hydroxy groups, carboxyl groups, epoxy groups, vinyl groups and amide groups can be used. Specific examples include 2-hydroxyethyl (meth) acrylate, 2-hydroxypropyl (meth) acrylate, 4-hydroxybutyl (meth) acrylate, 6-hydroxyhexyl (meth) acrylate, 2-hydroxy Monomers containing a hydroxy group such as oxyethylene glycol (meth) acrylate and 2-hydroxypropylene glycol (meth) acrylate; Monomers containing a carboxyl group such as (meth) acrylic acid, maleic acid, or fumaric acid; Or monomers containing nitrogen such as acryl amide, N-vinyl pyrrolidone or N-vinyl caprolactam. These may be used alone or in combination of two or more thereof.

The content of the monomer containing the crosslinkable functional group is preferably 3 to 15% by weight of the total content of the acrylate-silicone copolymer. If the content is less than 3% by weight, there is a low probability of hardening reaction, so that the unreacted acrylate-silicone copolymer may fall off to the pressure-sensitive adhesive layer. If the content exceeds 15% by weight, the crosslinking reactivity is increased to decrease the storage stability of the pressure-sensitive adhesive. do.

The acrylate-silicon copolymer obtained as mentioned above is manufactured by mixing and curing a well-known hardening | curing agent, and a hardening | curing agent improves the durability of a mold release process layer, and functions to prevent falling to an adhesive layer. As the curing agent used for this purpose, one or more curing agents selected from the group consisting of isocyanate compounds, epoxy compounds, melamine resins and aziridine compounds can be used. The amount of the curing agent is preferably included in 0.01 to 10 parts by weight based on 100 parts by weight of the acrylate-silicon copolymer.

If the acrylate-silicon copolymer and the curing agent alone in the configuration of the release layer is a slow reaction rate, and there is a limit to lower the temperature of the reaction, a catalyst that helps the reaction of the crosslinkable functional group and the curing agent included in the copolymer May additionally be used. As the catalyst for this purpose, one or more kinds from the group consisting of amine compounds, tin compounds and non-tin compounds can be used.

Specific examples of the amine compound include tertiary amines such as benzyldimethyl amine, trisdimethyl amine methylphenol, triethylene diamine and tributyl amine; Quaternary amines such as triethylbenzyl ammonium chloride and tetramethyl ammonium chloride; Imidazoles such as 2-methyl imidazole, 2-ethyl-4-methyl imidazole and 2-phenyl imidazole.

Specific examples of the tin compound include di (tri) butyl tin dichloride, dibutyl tin oxide, dibutyl tin dibromide, dibutyl tin dilaurate (DBTDL), dibutyl tin diacetate, dibutyl tin sulfide, Tributyl tin oxide, tributyl tin acetate, triethyl tin ethoxide, tributyl tin ethoxide, dioctyl tin oxide, tributyl tin chloride, tributyl tin trichloro acetate, 2-ethylhexane tin and the like.

Specific examples of the non-tin compound in the catalyst include titanium-based compounds such as dibutyl titanium dichloride, tetrabutyl titanate and butoxy titanium trichloride; Lead systems such as lead oleate and lead naphthenate; Iron-based compounds such as 2-ethylhexane iron acetylacetonate; Zinc-based compounds such as zinc naphthenate; Zirconium compounds such as zirconium naphthenate; Cobalt system, such as 2-ethylhexane cobalt, etc. are mentioned.

The above-listed catalysts may be used alone or in combination of two or more thereof, and preferably included in an amount of 0.01 to 3 parts by weight based on 100 parts by weight of the acrylate-silicon copolymer.

Hereinafter, the present invention will be described in more detail with reference to Examples. This embodiment is intended to illustrate the present invention in more detail, and the scope of the present invention is not limited to these examples.

The initial peeling force, the peeling force with time, the residual peeling force, and the reflection appearance characteristics were measured using, and the results are shown in Table 2 below.

a. Initial peel force

After attaching the Nitto 31B to the coating surface of the prepared release layer with a roller of 2 kg, and allowed to stand for 1 hour at room temperature, it was measured using a tensile tester at 180 ° angle and 0.3m / min peel rate (JIS Z Condition 0237).

b. Peeling force over time

After attaching Nitto 31B to the coated surface of the prepared release layer with a roller of 2 kg, heat treatment at room temperature for 1 hour at 100 ° C. for 30 minutes, and after 1 hour at room temperature, 180 ° angle and 0.3 m / min peel rate It was measured using a tensile tester (JIS Z 0237 conditions apply).

c. Residual peeling force

After attaching the Nitto 31B to the coated surface of the prepared release layer with a roller of 2 kg, after 30 minutes at room temperature, peeled off the Nitto 31B and attached to the untreated PET film with a roller of 2 kg, release treatment Nitto 31B, which is not attached to the surface, was attached to an untreated PET film with a roller of 2 kg, and the peel force measured was compared with Equation 1 below. In general, if it is maintained at 90% or more, it can be said that little transfer occurs in the release layer.

[Equation 1]

Residual Peeling Force (%) = (Peeling Force A / Peel Force B) X 100

(In the above, the peeling force A is the peeling force on the untreated PET surface of Nitto 31B adhered to the coated surface of the manufactured release layer, and the peeling force B is the peeling force on the untreated PET surface of Nitto 31B.)

2) Reflective appearance characteristics

Since the polyolefin film used itself had a haze of about 20 to 50%, it was difficult to see the appearance of transmission, and the appearance characteristics of the reflection were observed. After laminating about 100 mm wide black tape on the opposite side of the coated surface of the prepared release layer without air bubbles about 200 mm, the reflection appearance of the coating layer was observed in a three-wavelength lamp and summarized in Table 3 according to the following criteria.

○: When the coating is clean without marks on the coating bar

△: marks on the coating bar are not clear but appear uneven

X: Marks of coating bars appear continuously and are observed with various colors
