Description of the invention (1) The invention is based on a water-based coating composition, which can be used as a coating that can be used to coat both the interior and exterior walls of buildings. An elastic base coating composition; the present invention also relates to a final coating method, by using the water-based coating composition, it can form a multilayer film with good modified appearance and excellent durability. In this technology, it is generally known that a multi-layer modified paint method can be used to coat the wall of a building structure, which includes the use of some paints such as primer, middle paint, surface paint and the like to modify decorative materials. Even pattern. The above-mentioned modified coating method may include a synthetic resin emulsion-based multilayer modified coating method and a cement-based or polymer-cement-based multilayer modified coating method. The former includes forming a four-layer film by using sealer, primer, mid-coat material, and surface paint. The sealer is used to improve the adhesion between the substrate and the primer. The primer is used To uniformly control the substrate, the middle lacquer is used to form a three-dimensional decorative pattern on the modified surface, while the surface lacquer is used to provide a beautiful appearance and durability. The advantage of the above method is that it can form a highly decorative pattern with considerable variation in unevenness, but it also causes problems such as an increase in painting steps, cost, and work related to parks. On the other hand, the latter method uses a sealing paint, a cement-based mid-coat paint and a surface paint material to form a three-layer structure coating film, which is superior to the former in that the latter has one less painting step than the former. However, the latter method still has a problem: cement-based coatings are usually hard, and K causes poor elasticity, which causes many cracks to form on the surface of the film (such as the wall of a building structure). Ignoring these cracks will cause rain and dioxide. 3- This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) (Please read the precautions on the back before filling this page).

Uniform absorption, and the resulting modified appearance is not good, while making the film strength of the aforementioned film poor. Under the environment of 201C, the film formed by using the water-based coating composition of the present invention has an elongation of 30 to 250 ί, and K40 to 1403; preferably between. The elongation of the film was measured by using a universal tensile tester with a constant temperature chamber (trade name Autograph AG 2000 Type B, sold by SHIMADZU) at a stretching speed of about 200 mm / minute until Data obtained until the test piece ruptured at 20 °. The test specimens used for testing were prepared in accordance with JIS-A-6909. When the elongation is less than 30¾, the obtained film cannot sufficiently follow the cracks on the substrate. On the other hand, when the elongation exceeds 150 ¾, some small cracks may be caused in the surface paint, and the appearance of the surface will vary depending on the type of surface paint material applied to the resulting film.

Printed by the Consumers' Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling this page) The surface lacquer material used in the method of the present invention may include any one known to provide color and gloss to the surface of the modified film KK and water-based or organic solvent-based coating compositions that provide characteristics such as weatherability and water resistance to the modified film, without special restrictions; to be clearer, it may include, for example, acrylic resin and acrylic amine, respectively. Urethane resin, polyurethane resin, fluorocarbon resin, acrylic silicone resin and the like are the main components of the compound. The final coating method of the present invention includes M—a known coating device, such as a roller, an air spray gun, an airless spray gun, and a color cement coating gun-9. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X 297 mm) Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs 515828 A7 B7 V. Description of the invention (8) (lithin gun), general gun, brush, etc. Apply the water-based coating composition to the substrate or exposed coating On top of the film, M forms a thin film layer coated with an elastic base, and then the topcoat material is coated on the same device as described above to form a topcoat film layer. The water-based coating composition used in the elastic-based coating composition of the present invention has a coating condition of between 0.1 15 and 1.5 kg / m 2, and M between 0.3 and 1.3 kg / m 2. Better between meters. Such an aqueous coating composition is preferably applied to form a smooth surface or a smooth uneven surface. For example, the entire coating surface is filled with a pattern such as an orange peel surface and a crater surface. The coating condition of the surface lacquer material is more suitable between 0.1 and 0.5 kg / m 2. The invention obtains an aqueous coating composition which can be used in an elastic-based coating composition, which can crack along the surface of a substrate, and it can also be applied to the surface of an exposed coating film. If the surface paint material is a solvent-based material, the present invention can also avoid the shrinkage of the coating film layer, and the water-based coating composition is applied to an organic solvent-based true paint coating composition and has a low solvent resistance. Exposed on the coating film, it can produce a multilayer modified coating calendar with good modified appearance and good durability. The present invention is particularly useful for simultaneously coating the inner and outer walls of a building.
