Description

  The present invention relates to an interior finishing method that suppresses cracks with time and has no influence on the surface treatment even with a smooth finish.

  Currently, there are wallpaper, paint, and coating materials for interior finishes, and the wall paper accounts for a considerable proportion in terms of ease of construction and cost. Among these, the coating material has high designability and is used in a field where design is important. This coating material is mainly a synthetic resin emulsion-based finish coating material (interior thin coating material E, interior thick coating material E, etc. stipulated in JIS A6909). When finishing interior walls, the main material of the base material is gypsum board. The cracks in the coating film are avoided to the extent that it is not comparable to wallpaper due to the design and high quality of the coating material. Of these, time-lapse coating film cracks are mostly joints between the base materials, and joint processing is performed to suppress cracks and steps in the finish coating material even in various movements, including dimensional changes of the base materials. Is called. In this joint treatment, as a joint treatment for a taper edge gypsum boat having a taper of 40 to 60 mm in the width direction and a taper of 0.6 to 1.9 mm in the thickness direction, a hardened joint cement putty primer is applied in the taper, and a joint tape (glass Fiber) tension, hardened joint cement intermediate coating over about 150mm, dry emulsion putty over about 300mm 2-4 times (depending on the level of gypsum board unevenness, joint thinning), sandpaper (putty convex of the putty) Bevel edge gypsum board that has been chamfered 2-6mm and hardened joint cement putty, coated with joint tape (glass fiber), partially covered with joint tape, and dried about 250mm wide on both sides Dye-type emulsion putty, with a width of about 500mm centering on the joint, Rushonpate overcoat, (scraping protrusions putty, to smooth) sandpaper cliff is common. The purpose of the joint treatment is to increase the finish level of the top coat finish in addition to the above-mentioned movement of the groundwork. The former is processing in the width direction by taper, and the latter is the thickness of the joint tape. Treatments for absorption were included, and these depended on joint processing experience, and man-hours, labor, and proportion of all processes were not small.

  Paper with a three-layer structure in which pulp slurry is supplied to a papermaking fabric to form a basic paper quality, and wood chips are supplied onto the wet paper to form a surface paper quality. And a method for forming a concavo-convex pattern by applying a paint to a wall and applying a paint on the wall. (Patent Document 1)

Non-halogen flame retardant with interior material capable of realizing interior finish with new coloring effect and interior finish method using the interior material, with core component made of crystalline polypropylene and sheath component made of polyethylene with lower melting point than core component It is composed of a nonwoven fabric (or felt) manufactured from a web made of polyolefin core-sheath composite fiber, and the basis weight of the nonwoven fabric (or felt) is 40 g to 200 g / m ² and the thickness is 0.3 to 3 mm. Is disclosed. (Patent Document 2)

These are used as wallpaper, and paint is applied, but it makes use of the embossing or makeup of the wallpaper, and the embossing makes the unevenness of the background inconspicuous and becomes the design itself. The present invention is a layer structure or method in which a design is produced only with a building finishing material, cracks are not generated in the layer structure (actually the surface) of the building finishing material, and the design of the building finishing material is sufficiently drawn out.
Japanese Patent Laid-Open No. 2-167953 JP 2006-37261 A

The synthetic resin emulsion-based finish coating material is a method for applying a coating material, and provides surface finish, that is, various surface finishes by spraying, rollers, wrinkles, and the like to impart design properties. The wallpaper is made of the wallpaper itself, that is, with a color pattern and embossing, has a design, and makes the background and joint defects inconspicuous. In addition, the paint mainly has a color pattern, and the paint itself does not exhibit a design largely based on the surface form, but an embossed design with the aid of processing on the ground.
For this reason, although synthetic resin emulsion-based finish coating materials are rich in design expression, they are susceptible to the influence of joints, especially joints. Although the processing was troublesome, the effect of the swelling of the joints and the like was still unable to eliminate the poor designability (it can be seen that the joints were treated).

  The problem to be solved is a method that does not cause cracks in the building finish coating material, can easily perform the joint treatment process, and does not impair the design expression of the building finishing material.

  The invention of claim 1 is an interior finishing method in which a paper nonwoven fabric is applied to a wall base material and a synthetic resin emulsion-based finish coating material is applied. Cracks with time do not occur, and the number of steps and time can be reduced.

According to a second aspect of the present invention, the base material according to the first aspect is a base material that has been chamfered by 2 to 6 mm, a putty is embedded in the joint portion of the butted base material, and a paper nonwoven fabric is pasted on the entire surface of the wall. This is an interior finishing method in which a finish coating material is applied on top of it, so that cracks over time do not occur and the finish of the building finish material is not affected by the ground joints, regardless of the skill of the groundworking operator. .

The present invention is an interior finishing method in which a paper nonwoven fabric is pasted on a wall base material and a synthetic resin emulsion-based finish coating material is applied. The base material is a base material that has been chamfered by 2 to 6 mm. An interior finishing method in which putty is filled in the joints, paper non-woven fabric is applied to the entire surface of the wall, and a finish coating material is applied onto the wall surface. There is an advantage that it does not affect the finish.

  In the present invention, the mounting of the base material depends on the structure of pillars, studs, etc., and further depends on the structure of the building, but the allowance of the base joint part of the wall is large, and the coating amount of the building finishing material is small, even with a smooth finish. There was no joint processing trace on the surface, and the zero span tensile test was evaluated for the above-mentioned tolerance.

  The chamfering treatment of 2 to 6 mm of the gypsum board may be a bevel edge according to JIS A6901 or a chamfered square edge product. Putty can be used for filling holes in walls. Any material that does not have meat waste (does not lose weight after curing) may be used. Sanding after drying should be done to the extent that it does not affect the finish.

  The paper non-woven fabric is pasted on the entire surface where the finish coating material is applied by removing the butt joints of the base material and cutting them together. At this time, the paste may be a mixture of ordinary starch paste or vinyl acetate emulsion (adhesive). If there is no special requirement, the blending ratio is determined in consideration of workability and drying property.

  After pasting the paper non-woven fabric, apply the finish coating material. At this time, the non-woven paper paper and the synthetic resin emulsion finishing coating material, which are finishing coating materials, interact with each other. A zero-span tensile test evaluation that cannot be obtained with paper nonwoven fabric alone or finish coating material alone is obtained. That is, crack resistance when actually constructed is obtained.

The paper non-woven fabric is good as long as it has an interaction with the finish coating material. However, it is preferable that the paper non-woven fabric is manufactured in a wet manner in view of workability when bonded to the wall, surface smoothness, interlayer strength, and the like. The coating material is water-based, and blending with synthetic resin fibers is preferable until the finishing coating material is dried and considering that the finishing coating material receives in the surrounding environment, that is, moisture resistance. In addition, blending with polyester fibers is preferred from the standpoint of adhesion to the finish coating material. A preferred commercially available material is Lunafather (pulp: polyester fiber = 1: 1, 136 g / m ² , Nippon Lunafather, trade name).

The finish coating material is a synthetic resin emulsion-based finish coating material corresponding to the interior thin coating material E, the interior thick coating material E, etc. specified in JIS A6909. The synthetic resin emulsion is blended, and the solid content ratio of the synthetic resin is 5 to 5. It contains 20%, and aggregates, fillers, pigments and the like are included in terms of workability and design. An acrylic copolymer resin is suitable because it can be designed such as adhesion and flexibility.
Commercially available products include Jolipat JP-100, Jolipat Neo JQ-650, NEW Silky Palette JQ-20, JQ-55 (above Aika Industry Co., Ltd. product) and the like.

As Example 1, a 9 mm gypsum board having a width of 50 cm and a height of 1 m and a chamfered chamfer (bevel edge) of 5 mm in the vertical direction end face were abutted with the gypsum boards and putty (Yoshino gypsum) was put on the joint. Tiger Joint Cement Co., Ltd. (powder), trade name) was filled with a putty spatula, and after 6 hours as a paper nonwoven fabric, Luna Father Freeze No. 741 (manufactured by Nippon Lunafather Co., Ltd.) is applied with wallpaper adhesive (Yazawa Chemical Industry Co., Ltd., Wall Bond 100, trade name) in the longitudinal direction and the longitudinal direction of the nonwoven fabric, and after 6 hours, as a finish coating material New finish silky palette JQ-55 (Aika Kogyo Co., Ltd., architectural finish coating material, trade name) was subjected to a smooth finish of 2.0 kg / m ² to evaluate the finish and joint treatment dependency. The zero span tensile test was performed in the same manner as described above with a size of 70 mm × 70 mm and a thickness of 9 mm, and a test piece was prepared as shown in FIG.

  The gypsum boat of Example 1 was made a square edge without chamfering treatment, and the same procedure as in Example 1 was carried out except that joint processing was not carried out.

Comparative Example 1
Comparative Example 1 was carried out in the same manner except that LB-9401 (manufactured by Rilikara Co., Ltd.), which is a vinyl chloride wallpaper lined with a nonwoven fabric, was used instead of the paper nonwoven fabric of Example 1.

Comparative Example 2
Comparative Example 2 was carried out in the same manner except that the paper nonwoven fabric of Example 1 was eliminated (no gluing).

Comparative Example 3
Comparative Example 3 was carried out in the same manner except that the paper nonwoven fabric of Example 2 was eliminated (no gluing).

Comparative Example 4
Tiger G fiber tape (Yoshino Gypsum Co., Ltd. glass fiber 50mm width, product name) is applied to 5mm chamfered bevel edge plasterboard, and Tiger joint cement (product name putty) is applied to this tape width. As an undercoat (filling joints, fixing tape), putting a putty on the both sides of the tape as a middle coat, applying about 250mm wide on the both sides, and then applying a putty top coat with a width of about 500mm around the joint, as a typical joint treatment example As a building finish coating material, NEW Silky Palette JQ-55 (Aika Kogyo Co., Ltd., building finish coating material, product name) is smoothed to 2.0 kg / m ² to evaluate the finish and joint processing dependency. did. The zero span tensile test was performed in the same manner as described above (on the test piece) with a size of 70 mm × 70 mm and a thickness of 9 mm, and a test piece was produced as shown in FIG. This was designated as Comparative Example 4.

Comparative Example 5
Instead of the paper nonwoven fabric of Example 1, Luna Father Freeze No. The building finish was applied under the same conditions as in Example 1 instead of 707 (embossed product manufactured by Nippon Lunafather Co., Ltd., product name). 707 (trade name) spontaneously peeled from the base material together with the building finishing material. It is considered that the architectural finish coating material is different from the wallpaper paint in that it results in different thick coatings, aging humidity and stress.

  The base material was removed, and the characteristics of the paper nonwoven fabric and the material used in the comparative example were measured according to the JISP8113 standard. Those with anisotropic characteristics are measured longitudinally and laterally and are shown in Table 2. Table 3 shows the results of the zero-span tensile test of some paper nonwoven fabrics and similar sheets. The effect of the present invention is not a strength but a possibility due to elongation. The composite of Reference 4 is larger than the tensile break elongation (lateral) of Reference 1 nonwoven fabric and the tensile elongation of Reference 3 (JQ-55). On the other hand, the vinyl chloride wallpaper of Reference 2 is worse than the composite of Reference 5, and it can be seen that there is a peculiar interaction between the paper nonwoven fabric and the finish coating material. Note that the comparison of the sides corresponds to the actual construction.

Zero-span tensile test A test piece as shown in Fig. 1 is produced around the joint. The width is 70 mm, the base materials are only butted together, and the stress is applied to other parts. The conditions were created under the conditions of Examples and Comparative Examples, and after applying the building finishing material, left still for 14 days in an environment of 23 ° C. and 50% relative humidity, and pulled with a universal testing machine as shown in FIG. The distance at which the crack occurred was the zero span distance, and the maximum load displacement was the maximum displacement distance. In addition, none of the test pieces was peeled and broken between the respective layers after breaking.

  As for crack resistance, a zero span of 2.3 or more was evaluated as ◯, a value of less than 2.3 or more as 1.8, and a value of less than 1.8 as x.

  As for the finishing property, “○” indicates that the surface appearance is good after applying and drying the building finishing material, and “×” indicates that the joint or the joint-treated trace can be seen.

  Dependence on joint treatment is ○ for those with good surface finish of building finish without depending on mounting of base material, △ for those with good surface finish of building finish only when mounting is good, good mounting Even if the surface finish of the building finishing material was poor, it was rated as x.

  In the case of comprehensive evaluation, crack resistance, finish, and joint treatment dependency, there was no mark with ◯, and the mark with x was marked with x.

The material of Table 2 is the material used for the Example and the comparative example, and JP-100 is Jolipat JP-100 (Aika Kogyo Co., Ltd. architectural finish coating material, trade name). Tensile strength and tensile elongation at break were tested and calculated according to JISP8113. Test piece size 15 mm wide × 250 mm long 180 mm between chucks The test was performed at a pulling speed of 20 mm / min.

The composition is the material alone, the classification of the combination, and the concrete contents are described in composition 2.

Reference 3 shows the width of the architectural finish coating material, and JQ-55 used in the comparative example of the example can be regarded as having little elongation.
