Description of the Invention: [Technical Field] The present invention relates to a film for protecting a coating surface, and a coating surface protective film suitable for protecting a coating surface of an automobile. ‘*About [Prior Art] Protection of the painted surface of various painted products. For example, in the case of a car = a security officer, to protect the coating from sand or acid rain: or a protective film on its painted surface. In the case of the above-mentioned coating surface protection film, the coating surface protective film is generally composed of a polythene resin film, and an adhesive layer is formed on one side thereof (refer to the patent document υ. That is, the protective film system) It is attached to the surface to be mounted via an adhesive. However, when the resin film is attached to the coating surface by an adhesive, air bubbles may be trapped between the film and the coating surface. When there is a bubble between the surface and the film, the following problems occur: the moisture in the bubble is condensed by the temperature, and the coating surface is discolored by the condensed water. Therefore, in order not to entrap the bubble, it is necessary to use the scraping. The squeegee carefully attaches the previous protective film having the adhesive layer formed on the entire surface to the coating surface. In Patent Document 1, it is proposed that the volume of the bubble is not easily caused in the operation for using the squeegee. Into, and partially improve the adhesion of the adhesive layer. However, in the above method, it is necessary to use a scraping plate when applying the protective film to the coating surface. Therefore, it is difficult to apply the protective film to the base of the three-dimensional coating surface. This question. Again, There is a problem that in order to partially improve the adhesion of the adhesive layer, the following cumbersome method is required: it is necessary to apply a partial thickness to make the thickness of the adhesive layer partially different. In summary, the method proposed in the patent document [ There is a fatal defect that the protective film cannot be simply applied to the coated surface. On the other hand, it has been confirmed that even if a porous film having a water-impermeable function and having gas permeability is used as the resin film coated with the adhesive, even When there is air in the Fb1 of the film and the coated surface, there is no appearance of condensation. Therefore, it is also considered that the porous film is cut into the shape of the coated surface to be protected 'on the periphery of the porous film A double-sided tape is attached, and the porous film is attached to the coating surface of the coating surface by the double-sided tape so that water does not penetrate into the portion covered by the porous film. The heart is also present in the method. It is extremely cumbersome to cut the porous membrane into a certain size. It is necessary to attach double-sided tape to the outer surface of the cut porous membrane. It is difficult to apply the protective film. Coating No. 2: Patent Document 2 proposes: a sheet for a porous sheet-side sheet: a coating film for forming an adhesive layer in a dot shape or a stripe shape (coating surface protective film) The sheet can be simply applied to the coated surface. However, the portion of the moisture between the sheet surfaces of the coated sheet is protected (4) and the coated surface of the sheet and the coating is changed to D' and prevented by 醆Rain or washing liquid can be easily concentrated. Therefore, the sheet used is high in moisture permeability, ^, volatilization on the whole surface, and at the same time, to make moisture from the sheet. 4 201132731 =: forming an adhesive The non-pointing surface of the layer with high moisture permeability becomes a large area. Therefore, it is possible to prevent the surface of the coating surface from being deteriorated by the partial acid rain of the water or the concentration of the washing liquid, but the sheet and the coating of the water The space between the faces: the water that is easily infiltrated into the water will spread in the entire surface of the non-adhesive surface. The result is not only unable to suppress the coating surface... but also the discoloration is easy throughout the patent document 1: Japanese Patent Laid-Open No. 2001 - 3 1923 Patent Document 2: 曰本特开平丨i — 7丨559号SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a surface coating that can effectively prevent the moisture-induced discoloration, and can be easily bonded to the coated surface of the coated surface of the protective Ge. In order to achieve the above object, the present inventors have conducted intensive studies and found that a dot is applied linearly on one surface of a porous film having gas permeability and water-impermeable property to form an adhesive line 'adhesive agent'. The film is attached to the coating surface; according to the form of the adhesive line, the non-adhesive surface of the uncoated adhesive is divided into a plurality of small unit surfaces independent of each other, thereby reliably preventing condensation from being generated. Further, the water infiltration can be easily attached to the coating surface and the protective coating surface can be reliably protected even when it is cut at an arbitrary position, thereby achieving the object of the invention and completing the present invention. According to the present invention, there is provided a coating surface protective film comprising a porous film having gas permeability and water permeability, wherein an adhesive is applied to one surface of the film, and is adhered to the film via the adhesive. The coating surface is characterized in that: 5 201132731 The adhesive is linearly coated to form an adhesive line, and the line is a base line extending continuously along both side ends of the film, and connecting the 2 The strip base is composed of a plurality of split lines extending in the width direction of (4) by the above-mentioned dividing line, and the film between the above-mentioned base lines is provided with a plurality of independent non-adhesive porous surfaces. Preferably, the coated surface protective film of the present invention comprises: a continuous adhesive line comprising a subdivided line connecting the dividing lines formed at adjacent positions to each other by the subdivided line 'by the above-mentioned non-pointing The porous surface is further divided into small unit surfaces which are independent from each other, and (2) the unit surface has a honeycomb shape, and (3) the long porous film is formed into an upper inner side and wound into a roll shape. 4) Attached to the painted surface of the car. In addition, in this specification, _ "strictly speaking, including sheets. & thickness, there is no coating surface protective film of the present invention which has a large feature in the following aspects. And (4) the entire surface of the film is coated with a dot for attaching the film to the coating surface, but is formed into a line shape. That is, the surface of the protective film is a porous surface having gas permeability and water permeability. The portion of the porous surface to which the uncoated adhesive is applied is a porous surface which is non-spotted to maintain gas permeability and water permeability. In the present invention, the adhesive is formed by applying an adhesive in a line shape. Adhesive line has: linearly extending continuously on both sides of the long film. 1I @ Λ ^ 2 baselines of the heart, and several dividing lines extending in the direction of the money width by the method of 6 201132731 of the two (4) two baselines; the film surface between the m and 2 baselines is divided into mutual symmetry by several dividing lines Non-adhesive. As understood from the above structure, the surface of the adhesive surface of the coated surface of the present invention is coated with an adhesive side (i.e., the surface attached to the side of the coated surface will be adhered to A plurality of non-adhesive porous surfaces that are completely surrounded by the line elements are used as a unit surface, and are covered by the unit surface. Therefore, when the protective film is attached to the coated surface, it can be broken! {太uu △ , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , When the porous film of the long strip is cut at any position and the clear shape of m is attached, it is also attached to the coating surface in the case where the entire surface is coated with an adhesive, and the scraping plate can be omitted. Such components, no blistering, easy to attach work. In the protective coating film of the bright surface, even if it is caused by an accident or the like, the A coating causes a partial breakage of the film, and no water seeps into the entire painting degree.嘁 嘁 而 而 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制 抑制Separately divided into smaller unit surfaces, the above advantages will be achieved in such a way that it is best to divide such a small early surface into a bee-away shape. Side coating surface protection In particular, the film is wound around the surface on which the adhesive line is formed, which is easy to use, and is also advantageous in the work. 201132731 The protective film is especially attached to the painted surface of a car. [Embodiment] Referring to Fig. 1 which shows a representative (four) of the coating surface protective film of the present invention, the film is coated in a linear form by one surface of the entire long porous film. When the adhesive line is formed, the adhesive line is represented by i and 2. That is, the protective film is attached to the coating surface to be protected by the adhesive lines. The porous film 1 () of the present invention has gas permeability and water permeability. For example, the gas permeability of Gurley is preferably 3 sec / lOOcc or less, and particularly preferably 5 〇 2 〇〇〇 / 1 〇〇 (^, more preferably ~ 1 〇〇〇) In the range of y / 100 cc, the non-permeable property is preferably based on jis - [the water pressure resistance is 8 kPa or more. The porous film 1 〇 may be made of a resin as long as it has gas permeability and water repellency as described above. It is made of any material such as paper or non-woven fabric. However, in consideration of moldability, strength, cost, ease of application of an adhesive, etc., it is preferable that a resin-made resin or a porous film made of a resin has a financial viewpoint. Preferably, the titanium oxide is blended in an amount of from 1 to 20% by weight, particularly preferably from 5 to 15% by weight, in the crucible. Further, the resin having the gas permeability and the water-impermeable property as described above is porous. The plasma film itself can be produced by various known methods, but a typical production method is as follows. That is, a method of preparing a resin composition in which a porous agent such as rocky soil or inorganic powder is dispersed in a thermoplastic resin is prepared.

Further, the removal of the porous agent after the stretching of the film is carried out by using a binder, a solution by acid, or the like. Of course, the removal operation is not particularly required when the gas permeability of the film is imparted only by the holes generated in the drawing operation. ★The thickness of the porous film 10 depends on the form or size of the coated surface to be protected. 4 It is not suitable for the proper range. It is generally 15 to 500 " m, especially about 50 to 200 // m. In the present invention, the resin-made porous film 10, which is particularly suitable for use, is, for example, SUNMAp (trade name) manufactured by Nitto Denko Co., Ltd., POLAM (trade name) manufactured by T.K. . In the present invention, the adhesive for forming the adhesive line can be used. The known adhesive used in the conventional protective film for the coated surface is not particularly limited, and in general, a rubber-based adhesive is preferably used. 9 201132731 Examples of such rubber-based adhesives include polyisobutylene, butyl rubber, polybutene, styrene-ethylene-butylene-styrene copolymer (SEBS), styrene-ethylene-propylene-benzene. Ethylene copolymer (SEPS), styrene-butadiene-styrene copolymer (SBS), styrene-isoprene-styrene copolymer (SIS), or the like, or such argonized products. In the present invention, the above-mentioned adhesive is applied in a linear manner, and the film 1 〇 is attached to a specific coating surface by the formed adhesive line. In the present invention, it is necessary to form the adhesive line in a specific pattern, as shown in Fig. i, the β-adhesive line includes two base lines continuously extending on both sides of the long porous film 1 、, and A plurality of dividing lines 2 extending in the width direction of the film 1 连接 in a manner of connecting the baseline. By forming the baseline 划分 and the dividing line 2 as described above by using an adhesive, the surface of the film 1 位于 between the 丨 and 丨 is divided into a plurality of independent non-adhesive porous faces 3 . That is, the surface of the film 10 is divided by the adhesion lines (base line 1, i, and division line 2), and the completely independent non-adhesive porous material becomes a unit surface from 3, and becomes a surface covered by such a unit surface of a large size. Therefore, when the film is attached to the specific coating ©, it is possible to surely prevent water from penetrating into the space between the unit surface and the coating surface. Further, since the porous membrane 1 has high gas permeability, it does not cause a problem of condensation in the space. > Further, the surface between the two sides of the baseline Η is covered with the non-adhesive porous surface 3, so that the film 1 is cut at any position and attached to the coated surface. The same protection effect is usually obtained. Further, since the adhesive lines (base lines 1, 1) are formed at both side ends of the long strips, it is easy to attach to the coated surface as in the case where the adhesive is applied to the entire surface of the film 1 . In the case of the 201132731, it is easy to attach to the painted surface, and it is possible to ignore the intrusion of the air bubbles and attach them as a three-dimensional surface of the surface of the automobile body. Further, even in the case where the film attached to the coating surface is partially broken, the non-adhesive porous surfaces 3 are completely separated by the adhesive line, so that the water is infiltrated (four) in existence. The portion of the damaged non-adhesive porous surface does not cause problems such as water permeating the entire coating surface, and the knot can minimize damage. In the coating surface protective film of the present invention as described above, a base line in which the adhesive continuously extends is formed on both side ends of the elongated porous film 10, respectively! And a plurality of dividing lines 2 extend in the width direction of the plasma film 10 in such a manner that the two base lines i are connected to each other. By this, as long as a plurality of lines are separated by the dotted lines 1 and 2, they are independent. The non-adhesive porous surface 3 is formed into various forms by forming a line. _ For example, in the example of Fig. i, the two baseline turns extend linearly, and the lines 1 and 1 can also be extended in a dentate shape. Also, baseline 1,! It is also possible to extend the portion slightly on the inner side from the both ends of the porous membrane 丨Q. ° In the example of Fig. 1, the dividing line 2 and the two base lines 1 and 丨 are positive, so that the non-adhesive porous surface 3 which becomes the unit surface becomes a rectangular shape. The dividing line 2 can also be inclined with 2 base lines 1 , 1 intersect, and the line of intersection and skew line can also exist. For example, the baseline 1 is, for example, the baseline 1 is alternately formed. In Figure 2, which shows another aspect, the dividing line is composed of a line 2a orthogonal to 2 1 and a line 1 oblique to 2 baselines 1 Then, the non-adhesive porous surface 3 of the unit surface becomes a Sany" shape. 201132731 Further, in Fig. 1 and Fig. 2, Xirumu #, t # ', the dividing line 1 2 3 4 is formed into a linear extension ‘and may extend in a zigzag shape.隹 Λ Α , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , For example, in the example of FIG. 3, 划分. The two dividing lines connecting the two base lines 1 '1 are formed in a zigzag shape' and then connected. The adjacent dividing lines 2, 2 are formed to form a plurality of strips in the longitudinal direction of the film 10. Extend T t .,, the field knife line 5. That is, in the example of Fig. 3, the singularity of the example of Fig. 1 or Fig. 2 goes to ^ω々 "c," and the non-adhesive porous surface 3 of the wealth is further reduced to a subtle bee by the subdivided line 5. In the early surface 3a of the shape of the monument, the unit surface 3a of the honeycomb shape is independent of each other and is in a state of covering the surface of the film 1 。. In the above invention, the smallest surface formed by each adhesive line, for example, FIG. 1 and The shape of the non-adhesive porous surface 3 in FIG. 2 or the unit surface in FIG. 3 can be set to an arbitrary shape according to the shape of the dividing line 2 or the subdividing line 5, and the size thereof is determined according to the size of the coating surface or the like. For the case of a suitable size, such as the case of the protective film used for the surface of the automobile, the minimum surface size as described above is preferably set to i~5, 〇〇〇Cm2' is particularly good. The width of each of the adhesive lines (baseline 12 1 , dividing line 2, and subdividing line 5) which is formed by applying an adhesive in a line shape is not particularly limited, and is not impaired. Many: the permeability of the plasma membrane 10 and ensuring a moderate degree of adhesion, generally 1~l〇〇mm 'especially 2~3〇mm is preferable, and the thickness thereof is ～(7) 3 //m, particularly 2 to 4 yni. 4 Further, in order to maintain the gas permeability of the porous membrane 1 within the above specific range, Preferably, the total area ratio of the adhesive line is set to be 50% or less with respect to the surface of the crucible surface (one surface). 201132731 The formation of the above various adhesive lines is not particularly (4), and since it is necessary, the pattern is preferably The following method is employed: a solution obtained by dissolving a specific two-two-dissolving adhesive is applied to a surface of the film by a printing method in a specific pattern, and then dried (d) in addition to the above-described examples of the present invention to FIG. In the meantime, the two sides of the two baselines I, 1 : 臈 10 are finely divided to give full play to the effect of the present invention: in terms of 3, the aspect is the best. That is, the shape of the adhesive eye in Fig. 3 Since the film is closely formed on the surface of the film 10, the film can be attached to the coating surface, and the bonding operation can be easily performed by neglecting the incorporation of air bubbles. Further, since the unit surface 3 is formed slightly and closely, Even if the film is cut and attached in any form, the protective effect is the same. Further, even if one of the membranes 1 is damaged, the ##t is minimized. (4) The damage can be suppressed, and the width of the long porous membrane 10 is set to an appropriate size according to the use. In the case of protecting the painted surface of the automobile, 30 to 20 〇cm 0: in the present invention, the porous film ι which is formed with the above-mentioned adhesive line can be easily attached, for example, as shown in the figure. In terms of work, it is preferable to use the side on which the adhesive line is formed as an inner side to be wound into a roll shape for use. In the case where it is wound into a roll shape as described above, it is preferable that the adhesive line is not provided. The embossing is provided on the side of the film surface, and the film 1 〇 can be quickly pulled out by the formation of the embossing calendar as described above, and the formation of the sth. The degree of embossing as described above is preferably, for example, in the form of 13 201132731: the average surface roughness of the film surface (four) is 2 to 1 〇 _ and the density of each convex portion is 1 〇, : 4~ 8 丨. Ten thousand, ten thousand. Further, the method of forming the text is not particularly preferred. The method of surface processing by an embossing roll (emb_rGll) is preferably used. When the film is wound up, for example, the pair is staggered in advance. A release film such as an S film is interposed therebetween, whereby the coated surface protective film of the present invention can also be pulled out by the crucible. Cutting off the name of the geek ~ Man's gland is pulled from the roll, for example, to the size of the special size, and attached to the painted surface to protect the painted surface. In this case, when the coating surface is the same as the coating surface of the automobile, a plurality of the films are cut out, and the side ends of the adjacent films of the plurality of films are attached so as to be attached. Further, for example, in the peripheral portion of the automobile body, it is preferable to apply a coating surface protective film of the present invention, preferably by applying an adhesive or attaching a pressure-sensitive adhesive tape to the surface of the automobile. ::: The film can be attached to the body of the car by the position of the end of the protective film applied to the car body or the attached double-sided tape. Further, after attaching the protective sheet of the present invention, the existing non-permeable tape can be used to seal the film to the peripheral portion of the vehicle body. When the film is at the above-mentioned clearing v, the adhesive used is the same as the adhesive used to form the adhesive line of the film. In addition, the coating surface of the present invention is reported as π Μ, and the enamel film not only protects the coating surface of the automobile, but also is preferably used as a household appliance for painting, (four), and a wood product to which the coating is applied. Protective film. Embodiment 14 201132731 The following table is not a yoke example, but the present invention is not limited to the embodiments. <Example 1 > Preparation of POLAM PUX manufactured by Tokuyama Co., Ltd. (width: 50 cm, thickness: 70 m, ear band Α 岢 thundering emulsion. 800 sec / i 〇〇 cc, water pressure resistance: kPa , Polyethylene film) 'as a long porous film. On the surface of the porous film, an adhesive line composed of butyl rubber is applied by a printing method to form an adhesive line (base line i and dividing line 2). The shape is as follows: Line width: 10 mm Line thickness: 3 ym Interval of adjacent dividing line 2: 9 〇 mm Area ratio of adhesive line: 12% will form a long porous film of adhesive line in the above manner to be appropriate The size is attached to the part of the iron plate surface on which the black coating for the automobile is applied. At this time, the number of the unit surface (non-adhesive porous surface 3) of the attached film is set to (7) 岫 2, and The part of the unit surface was torn. The iron plate to which the above film was attached was exposed to the outdoor (mountain area) for 3 months, and then placed under room temperature (four) soil vapor for 24 hours, and then the color of the painted surface was observed. Change. As a result, the color of the painted surface was not changed at all in the portion which was not torn, and only the portion of the unit surface to be torn was deteriorated in the same manner as the coated surface on which the film was not attached. <Example 2 > Using an average roughness (Ra) of 5/m, and embossing the density of the convex portion per 1 cm 2 to be 250,000, as a porous film, except 15 201132731 A coating surface protective film was produced in the same manner as in Example 1 except for the above. The prepared coating surface protective film was wound into a roll shape, and after holding at 8 (rc for 1 〇 minutes, the film was pulled out from the roll, and the resistance was measured, and as a result, compared with the case where the embossing treatment was not performed, The force required for the pull-out was reduced by 90%. Further, the film was attached to the iron plate surface on which the black paint was applied in the same manner as in Example ,, and exposed to the outdoor (Yamaguchi area). After the month, it was allowed to stand at room temperature (23 c ± rc ) for 24 hours, and then the change in the hue of the painted surface was observed. As a result, the color of the painted surface was completely unchanged in the unteared portion, and only the tear was torn. The part of the unit surface is deteriorated in the same manner as the coated surface of the unattached film. <Example 3> Adhesion is formed on one side of the porous film by forming a honeycomb unit surface in the pattern shown in Fig. 3 The line (the area ratio of the adhesive line was 20%). Using the film thus produced, it was attached to the surface of the iron plate on which the black coating was applied in the same manner as in the first embodiment (the unit surface) The number is 80 / m2), after exposure for 3 months in the outdoor (Yamaguchi area), at room temperature (23 (: ± 1 C ) placed for 24 hours ' Then observe the change of the color of the painted surface. The result 'in the un-teared part, the color of the painted surface is completely unchanged, only the part of the unit surface to be torn The coating surface to which the film is not attached is similarly deteriorated.
