Abstract
Description
The present invention relates to a pressure-sensitive adhesive improved in heat resistance and cold resistance, a method for producing the same, and a pressure-sensitive adhesive tape having heat and cold resistance improved by using the pressure-sensitive adhesive tape. More particularly, A pressure-sensitive adhesive having enhanced heat resistance and cold resistance, which is capable of preventing sticking at high temperature and stabilizing the pressure-sensitive adhesive at a low temperature, by producing a pressure-sensitive adhesive by blending and mixing a base resin; And a heat-resistant and cold-resisting adhesive tape produced by using the same.
Adhesive is a material that adheres sufficiently to the adherend even under the application of pressure alone. It exhibits a viscoelastic behavior in which the cohesion is lower than that of the adhesive, the stress relaxation is faster, and the deformation easily occurs with respect to external force.
The raw materials used in the pressure-sensitive adhesive are mostly elastic materials such as natural rubber, synthetic rubber, acrylic, and silicone, so they have viscoelastic properties by mixing low molecular weight materials to impart viscous properties.
Recently, acrylic pressure-sensitive adhesives among the raw materials of pressure-sensitive adhesives have been rapidly used instead of rubber-based pressure-sensitive adhesives, and they can be used in a wide variety of forms such as solvent type, water-based emulsion type, hot melt type and 100% solid reaction type pressure-sensitive adhesive. Compared to rubber-based pressure-sensitive adhesives, they are excellent in weather resistance, heat resistance, cold resistance and oil resistance, and can be relatively easily manufactured for various purposes and applications. Therefore, it has been suggested that the adherence of acrylic adhesives has enabled the adhesive products to be used in a variety of different applications as at present. When an epoxy group is contained in the acrylic adhesive, it exhibits heat resistance, weather resistance and excellent adhesion properties due to inherent properties of epoxy.
However, in general, the pressure-sensitive adhesive containing an epoxy functional group is crosslinked by adding a crosslinking agent. This method is a two-component method in which a crosslinking agent must be separately added. As a result, There are many difficulties in maintaining uniformity.
Adhesive properties can be generally evaluated by initial tack, adhesion and shear strength. The initial adhesive force is related to the glass transition temperature (Tg) of the polymer forming the pressure-sensitive adhesive, and the adhesive force is related to the glass transition temperature and cohesion of the polymer. When the pressure-sensitive adhesive is applied to the adherend, the cohesive force is a force between the molecules of the pressure-sensitive adhesive. When the intermolecular cohesive force is high, interfacial failure of the pressure-sensitive adhesive occurs. When the pressure is low, cohesive failure occurs and remnants are left on the adherend. It is ideal to design the adhesive so that breakage occurs.
On the other hand, adhesive tapes have been widely used for packaging, bonding, surface protection, and display purposes in various industries. In particular, it attaches to the surface of packaging materials for storage and transportation of various items such as postal items, movers, and commodities in daily life, thereby preventing the contents from being exposed to external environment, thereby preventing contamination and breakage, and securing the safety of products. The adhesive tape is also used to bind two or more articles. When used for this purpose, the adhesive tape should have good initial adhesion when adhered to the adherend and retain adhesive strength after adherence.
The adhesive tape usually has a structure in which a pressure-sensitive adhesive is applied to one side or both sides of one or more film-shaped substrates. If the adhesive strength of the adhesive is too high, the adhesive tape is firmly fixed to the adherend, so that a part of the surface of the adherend is peeled off when peeling off after long-term adhesion, and the residue of the adhesive remains on the adherend, There is an inconvenience to do.
Various methods for producing such an adhesive tape are known. For example, when a pressure-sensitive adhesive sol is prepared by stirring a raw rubber and a resin in a molten state at a high temperature in a solvent-free, non-solvent form, the rubber is swollen because the rubber is not swelled and the viscosity is high. A phenomenon occurs. In addition, heat due to friction during stirring reduces the molecular weight by cleavage of the rubber molecular chains. The decrease in the molecular weight of the rubber leads to a decrease in the adhesion force, which is disadvantageous in that the sol can not be formed in an optimized state.
A method of producing a pressure-sensitive adhesive tape by using a solution-type rubber pressure-sensitive adhesive has been developed as a method of improving the disadvantages of the above-mentioned pressureless pressure-sensitive adhesive. According to this method, adhesive tapes are manufactured through rubber aging, lowering of rubber, preparation of rubber adhesive solution, aging of adhesive solution, coating and commercialization. This is schematically described as follows. First, the natural rubber in the form of bale is softened at a room temperature of about 30-40 ° C for a certain period of time (aging step). The softened rubber is then passed between two rolls of a two-roll mill to form a thin sheet of about 3-4 cm thick (rubber step down). The rubber lowering is a process for decomposing and softening the cohesive network of the rubber. For this purpose, a roll mill, a Banbury mixer, a Kneader mixer and the like can be used. 2 - When rubber rolls are carried out using a roll mill, rubber, and pigments, fillers and reinforcing agents (if cotton tape is produced) as required. Various additives such as carbon, blended oil, wax, stearic acid, sulfur, accelerator and the like are added and kneaded for 2-3 minutes. At this time, the temperature of the roll is set differently depending on the type of rubber used. The obtained soft rubber sheet is dissolved in a solvent to a solid content of about 20% by weight to prepare a rubber-solvent-based sol-gel adhesive solution (a pressure-sensitive adhesive solution preparation step). The pressure-sensitive adhesive solution is stored in a tank so that the properties of the pressure-sensitive adhesive solution can be sufficiently stabilized while being agitated (aging step), transferred to a coating facility, and coated on the surface of a transparent film such as stretched polypropylene (OPP) . Subsequently, the coated pressure sensitive adhesive solution is dried using an appropriate drying means to produce an adhesive tape (drying step). The adhesive tape thus manufactured has a structure in which a base material is coated with a rubber adhesive. Finally, the produced adhesive tape is wound and packaged under compression (commercialization step). However, in the above-mentioned conventional method, methanol is added as a swelling inhibitor because the rubber is continuously swollen by the solvent during mixing and there is a risk of flooding out of the tank. The addition of methanol reduces the amount of the sol compared to the amount of rubber used, Becomes rough and unfavorably becomes unpleasant. Further, the compatibility between the rubber and the resin is deteriorated and the adhesive force of the finally produced adhesive tape is not satisfactory.
In such a situation, a pressure-sensitive adhesive tape having improved heat resistance and cold resistance can be produced which can improve initial adhesion and retention after adhesion in a more economical manner, prevent peeling at high temperatures, and stabilize the pressure-sensitive adhesive at low temperatures There has been a steady stream of demands on how to do this.
The present invention relates to a pressure sensitive adhesive which is excellent in adhesion and can prevent peeling at a high temperature by mixing a rubber as a main component with a C5 resin and a rosin resin and mixing them with muscovite to form a pressure sensitive adhesive, A method for producing the same, and a pressure-sensitive adhesive tape having improved heat resistance and cold resistance, which are produced by using the pressure-sensitive adhesive, which is capable of achieving stabilization of a pressure-sensitive adhesive.
The present invention also provides a pressure-sensitive adhesive improved in heat resistance and cold resistance, capable of producing a pressure-sensitive adhesive tape with enhanced heat resistance, insulation and cold resistance by adjusting only the additives while maintaining the application amount of the pressure-sensitive adhesive tape at a standard thickness, And a pressure-sensitive adhesive tape having improved heat resistance and cold resistance, which is produced using the adhesive tape.

5. Coating the substrate (S500)
The step S500 of coating the substrate is a step of applying the pressure sensitive adhesive prepared in the step S400 of kneading the compounded raw material and the melted muscovite to the surface of the substrate using a coating facility.
It is preferable that the substrate can serve as a release paper for reinforcing the strength while maintaining the adhesive force of the coated pressure-sensitive adhesive, providing excellent scratch resistance, providing a smooth surface, and preventing adhesion of the rubber pressure-sensitive adhesive to each other during winding.
For example, the substrate may be a stretched polypropylene (OPP) film, a polyvinyl chloride (PVC) film, a polyethylene terephthalate (PET) film, a polyethylene (PE) film, a polystyrene (PS) film, a polycarbonate A plastic film such as a polyurethane (PU) film, a nylon film, and a polyacrylonitrile film can be used. Preferably, a stretched polypropylene (OPP) film can be used.
The substrate may be a single layer or a multi-layer structure in which two or more films of different types are stacked depending on the purpose of use. The base material of the multilayer structure can be prepared by coextrusion, heat bonding, or laminating using an adhesive. The plastic film may be unstretched, uniaxially or biaxially stretched. The substrate may be a flat or irregularly formed film, and the coated surface may be surface treated by plasma treatment or the like in order to increase the adhesive strength with the adhesive formed by the coating.
In the present invention, a finally produced adhesive tape is used in applications requiring transparency and ductility, and a colorless transparent film such as a stretched polypropylene (OPP) film is preferable as a substrate.
The thickness of the base material can be determined in consideration of physical properties such as flexibility and heat resistance. If the thickness of the substrate is too thick, the flexibility is insufficient and the winding property is insufficient. If the thickness is too thin, defects such as curling or wrinkling may occur during coating, resulting in problems in productivity and unsatisfactory final quality.

The drying step S600 is a step of drying the substrate coated with the pressure-sensitive adhesive to produce an adhesive tape having desired properties.
If the drying temperature is less than 100 ° C, the drying speed is low and the productivity is low. If the drying temperature is more than 130 ° C, the pressure-sensitive adhesive or the substrate film Which may be undesirable. In the present invention, the drying step (S600) may be performed in an oven controlled in temperature in addition to the hot air drying method.
Thereafter, the dried adhesive tape is cut into a predetermined length and width, and is then wound on a frame having a predetermined shape, and then packaged for commercialization.
While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood that the invention may be practiced. It is therefore to be understood that one embodiment described above is illustrative in all aspects and not restrictive.
