Description

Technical Field

[0001] The present invention belongs to the technical field of building wall painting, and particularly relates to a grid tape for building decoration and a building wall painting process. Background Art

[0002] In order to increase the aesthetic feeling in the building wall painting project, grid lines with colors different from the main body paint are made on the wall. The traditional grid process is as follows: apply a primer for dividing seam color adjustment on the wall body, and wait for it to dry. Then use masking tape to paste and cover the required grid lines. Next, carry out the construction of the subsequent main body paint. After the construction of the main body paint is completed, remove the masking tape to expose the primer for color adjustment, forming a grid effect with a color different from the main body.

[0003] The traditional grid process has the following disadvantages: 1. It is necessary to paste the masking tape only after the primer for color adjustment is completely dry. Otherwise, the film formation of the primer for color adjustment is not good, and it is very easy to also adhere and remove the primer for color adjustment when removing the masking tape; waiting for the primer for color adjustment to be completely dry will greatly waste the construction period and affect the project progress.

[0004] 2. Even if the primer for color adjustment has been completely dry before pasting the masking tape, due to problems such as high viscosity of the masking tape, long pasting time, or rainy and humid weather, when removing the masking tape, the primer for color adjustment will be torn off, and it is necessary to re-paint and describe the grid lines, which is laborious and wasteful and affects the project progress.

[0005] 3. When pasting the masking tape on the wall, due to the wall surface flatness problem, it is impossible to make the masking tape fit tightly with the wall, which will cause the main body paint in the subsequent construction to penetrate into the gaps of the masking tape and contaminate the color of the primer for color adjustment, affecting the expected decorative effect of the wall. Summary of the Invention

[0006] The present invention aims at the above problems and provides a grid tape for building decoration and a building wall painting process that are convenient for construction, have good exterior decoration effects, save construction time, and do not require post-treatment.

[0007] In order to achieve the above object of the present invention, the present invention adopts the following technical solutions. The grid tape for building decoration of the present invention includes a single-sided release paper, and is characterized in that: a polymer plastic film, a dry film of water-based color-adjusting paint, and a water-based acrylic emulsion adhesive layer are sequentially arranged below the single-sided release paper; the non-release surface of the single-sided release paper is in contact with the polymer plastic film, the contact surface of the polymer plastic film and the release paper is a high corona surface with a corona value greater than 38 dynes, and the other surface of the polymer plastic film is a low corona surface with a corona value of 32-38 dynes.

[0008] As a preferred scheme of the present invention, the corona value of the high corona surface is 42 dynes.

[0009] As another preferred embodiment of the present invention, the corona value of the low-corona surface is 34 to 37 dynes.

[0010] As the third preferred embodiment of the present invention, the polymer plastic film is a PET film or a BOPP film.

[0011] Furthermore, the BOPP film is a high-gloss film or a matte film.

[0012] The beneficial effects of the grid tape for architectural decoration of the present invention are as follows: 1. The single-sided release paper is used on the outermost layer of the grid tape for architectural decoration of the present invention, which ensures that the finished tape will not adhere when it is wound into a roll and contacts the water-based acrylic emulsion adhesive layer. At the same time, it overcomes the problem that the polymer plastic film has a certain stretching elasticity, so that the tape will not be stretched when it is unfolded.

[0013] 2. The double-sided corona polymer plastic film of the grid tape for architectural decoration of the present invention and the adhesive surface of the single-sided release paper are high-corona surfaces, and the high corona value can effectively guarantee the bonding firmness with the paper surface; the corona value of the low-corona surface of the polymer plastic film is between 32 and 38 dynes, which can ensure that the conventional water-based color-matching paint forms a film on the low-corona surface of the polymer plastic film, and can make the dry paint film of the water-based color-matching paint continuously peel off from the low-corona surface of the polymer plastic film (through experimental tests, when the corona value is lower than 32 dynes, the conventional water-based paint will aggregate into beads due to low surface energy and cannot form a continuous film; when the corona value of the low-corona surface of the double-sided corona polymer plastic film is higher than 38 dynes, it will cause the conventional water-based paint to adhere to the polymer plastic film and cannot be continuously peeled off).

[0014] 3. The BOPP film is used in the present invention. When the high-gloss film is used, the dry paint film of the water-based color-matching paint can form a high-brightness smooth dividing line; when the matte film is used, the dry paint film of the water-based color-matching paint can form a matte dividing line, and the external visual effect is diverse and simple, with strong adaptability.

[0015] The architectural wall painting process of the present invention includes the following steps.

[0016] Step 1: First apply a water-based acrylic elastic waterproof emulsion with a glass transition temperature of -5°C at the dividing line.

[0017] Step 2: After pasting and pressing the grid tape to the wall coating area, subsequent paint construction can be carried out.

[0018] Step 3: After the main paint construction, since there is no substantial adhesion between the dry paint film of the water-based color-matching paint and the low-corona surface of the polymer plastic film, the composite body of the polymer plastic film and the single-sided release paper can be torn off, and the dry paint film of the water-based color-matching paint is adhered to the wall by the water-based acrylic elastic waterproof emulsion with a glass transition temperature of -5°C.

[0019] Beneficial effects of the painting process of the present invention: The waterborne acrylic elastic waterproof emulsion at -5°C of the present invention is applied to the wall surface, forming a two-way paste of the same material with the bonding layer of the waterborne acrylic emulsion of the dividing tape. Its bonding is strong, ensuring the firm adhesion of the tape; when the main paint and the waterborne color-tuning paint in the subsequent construction, the dry paint film and the elastic waterproof adhesive emulsion are all acrylic systems, the side of the dividing tape will adhere to the main paint, further strengthening the firmness of the tape adhesion, so that the tape can have the same service life as the main paint in the subsequent construction.

[0020] Although there is no substantial adhesion between the dry paint film of the waterborne color-tuning paint and the BOPP corona film and it can be easily peeled off, due to its vacuum integration, the subsequent main paint will not penetrate and contaminate, so the lines are straight and do not require post-painting touch-up, improving the construction efficiency and quality.

DETAILED DESCRIPTION OF THE INVENTION

[0023] The dividing tape for building decoration of the present invention includes a single-sided release paper 4, and is characterized in that: a high molecular plastic film 3, a dry paint film 2 of the waterborne color-tuning paint and a waterborne acrylic emulsion bonding layer 1 are sequentially arranged below the single-sided release paper 4; the non-release surface of the single-sided release paper 4 is in contact with the high molecular plastic film 3, the contact surface of the high molecular plastic film 3 with the release paper is the high corona surface 5 with a corona value greater than 38 dynes, and the other side of the high molecular plastic film 3 is the low corona surface 6 with a corona value of 32-38 dynes.

[0024] As a preferred embodiment of the present invention, the corona value of the high corona surface 5 is 42 dynes.

[0025] As another preferred embodiment of the present invention, the corona value of the low corona surface 6 is 34-37 dynes.

[0026] As a third preferred embodiment of the present invention, the high molecular plastic film 3 is a PET film or a BOPP film.

[0027] Furthermore, the BOPP film is a high-gloss film or a matte film.

[0028] The thickness of the high molecular plastic film 3 can be 12μm-38μm, preferably 13μm-18μm.

[0029] The water-based color-tinting paint film is formed by spraying conventional water-based color-tinting latex paint or water-based metallic paint on the low-corona surface 6 of the polymer plastic film 3 and drying it. The thickness of the water-based color-tinting paint film is 20 - 200 μm, preferably 50 - 100 μm.

[0030] The water-based acrylic emulsion adhesive layer 1 is a viscous coating with adhesiveness formed by spraying water-based acrylic emulsion on the surface of the water-based color-tinting paint film to dry to the touch. The water-based acrylic emulsion can be a water-based pressure-sensitive adhesive or a water-based acrylic elastic waterproof emulsion with a glass transition temperature of 0 to -20°C.

[0031] The building wall painting process of the present invention includes the following steps.

[0032] Step 1: First apply a coat of water-based acrylic elastic waterproof emulsion with a glass transition temperature of -5°C at the dividing line.

[0033] Step 2: After pasting and pressing the dividing tape 7 to the wall gluing area, subsequent paint construction can be carried out.

[0034] Step 3: After the main paint construction, since there is no substantial adhesion between the dry film 2 of the water-based color-tinting paint and the low-corona surface 6 of the polymer plastic film 3, the composite of the polymer plastic film 3 and the single-sided release paper 4 can be torn off, and the dry film 2 of the water-based color-tinting paint is adhered to the wall by spraying the water-based acrylic elastic waterproof emulsion with a glass transition temperature of -5°C.

[0035] Example 1: Dividing tape 7 for building exterior walls.

[0036] A BOPP matte film with a thickness of 13 μm is bonded and compounded with the single-sided release paper 4. The film surface in contact with the single-sided release paper 4 is the high-corona surface 5 with a corona value of 42 dynes. The release surface of the single-sided release paper 4 and the low-corona surface 6 with a corona value of 36 dynes are on the outside of the composite; the low-corona surface 6 is a matte surface. The latex paint is sprayed on the low-corona matte surface of the polymer plastic film 3, and the film thickness is 50 μm. After drying, a water-based acrylic elastic waterproof emulsion with a glass transition temperature of -5°C is sprayed. After it dries to the touch, it can be rolled up and cut into tapes with a width of 0.5 - 3.0 cm, and then packed and sealed in boxes.

[0037] During on-site construction of the building, first apply a coat of water-based acrylic elastic waterproof emulsion with a glass transition temperature of -5°C at the dividing line, and then paste and press the dividing tape 7 to the wall gluing area, and subsequent paint construction can be carried out.

[0038] After the main coating is applied, since there is no substantial adhesion between the latex paint and the BOPP film with a low corona surface 6, the composite of the matte film and the single-sided release paper 4 can be easily torn off, and the water-based latex paint is adhered to the wall by a water-based acrylic elastic waterproof emulsion with a glass transition temperature of -5°C; although there is no substantial adhesion between the water-based latex paint and the BOPP corona film and they can be easily peeled off, due to their vacuum integration, the subsequent main coating will not penetrate and contaminate, so the lines are straight and do not require subsequent painting and trimming.

[0039] The water-based acrylic elastic waterproof emulsion at -5°C is applied to the wall surface and the water-based acrylic emulsion adhesive layer 1 of the dividing tape, forming a two-way adhesion of the same material. Its strong adhesion ensures the firm adhesion of the tape; and since both the latex paint and the elastic waterproof adhesive emulsion and the main coating for subsequent construction use acrylic-based coatings, the side of the tape will adhere to the main coating, further strengthening the firmness of the tape adhesion, so that the dividing tape can have the same service life as the main coating for subsequent construction.

[0040] Example 2: Architectural interior wall decorative tape.

[0041] The process is the same as that described in Example 1, the difference is that the BOPP film is a high-gloss film and the low corona surface 6 is a high-gloss surface; the water-based paint used is water-based metallic paint; after removing the paper-plastic composite, a high-gloss metallic effect is formed and it can be used as a decorative line.

[0042] Example 3: Patterned architectural decorative tape.

[0043] The process is the same as that described in Example 1; the difference is that the water-based paints used are a combination of various and multi-colored water-based paints for construction.

[0044] The high corona surface 5 of the BOPP matte film with a thickness of 18μm is adhered and compounded with the single-sided release paper 4. The corona value of the high corona surface 5 is 40 dynes; the corona value of the low corona surface 6 is 35 dynes; the transparent water-based varnish is sprayed on the low corona surface 6 of the matte film, and the film thickness is 20μm. After it dries, a silk screen printing plate is used to print the color-tuned metallic paint on the film to form a pattern; after it dries, different colors of water-based paints are sprayed; after drying, a water-based pressure-sensitive adhesive is sprayed. It can be rolled up for slitting, packing, sealing and boxing after surface drying.

[0045] During wall construction, it is first pasted on the wall and then the subsequent coating is applied. After the construction is completed, after removing the paper-plastic composite, a matte, multi-colored and patterned decorative line is formed.

[0046] It can be understood that the above specific description of the present invention is only for the purpose of illustrating the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Those of ordinary skill in the art should understand that the present invention can still be modified or equivalently replaced to achieve the same technical effects; as long as the use requirements are met, they are all within the protection scope of the present invention.
