Problems solved by technology

However, nitro crack paint contains high VOC and uses nitrocellulose, which has poor environmental protection and safety performance.
At present, the domestic water-based wood paint market has just started, the product system is not perfect, and the construction process is not perfect. The surface effect basically only has several simple construction processes such as sealing, development, and American coating.

Embodiment 1

[0015] 1. Material processing (the material in this case uses birch wood):

[0016] Sanding: Use sandpaper to sand along the wood grain to remove burrs and sand marks on the surface of the material; preferably 240# sandpaper;

[0017] 2. Base color (primer): After mixing the water-based two-component crack primer and curing agent in an appropriate proportion, add iron red paste for coloring, according to 90g / m 2 Spray on the substrate.

[0018] 3. Topcoat: Spray one-component water-based crack topcoat immediately after the primer is sprayed, and the coating amount is 100g / m 2 .

[0019] After drying for 4 hours at normal temperature, a cracked paint film with a red background and a white surface with relatively large cracks can be obtained.

Embodiment 2

[0021] 1. Material processing (the material in this case uses MDF):

[0022] Sanding: Sanding with sandpaper to remove burrs and sand marks on the surface of the material; preferably 240# sandpaper;

[0023] 2. Base color (primer): After mixing the water-based two-component crack primer and curing agent in an appropriate proportion, add iron red paste for coloring, according to 90g / m 2 Spray on the substrate.

[0024] 3. Topcoat: After the primer is sprayed, the time period (about 10 minutes) before the surface is dry in the natural drying state, and then spray the one-component water-based crack topcoat, the coating amount is 80g / m 2 .

[0025] After drying for 4 hours at room temperature, a cracked paint film with a red background and a white surface with finer cracks can be obtained.

Abstract

The invention relates to a water-based crack lacquer construction technology. The water-based crack lacquer construction technology is characterized by comprising the following steps that firstly, materials are sanded, abrasive paper is used for performing sanding along wood grains, burrs, sand marks and the like on the surface of the materials are removed, and 240# abrasive paper is preferably selected; secondly, the water-based double-component crack primer and the curing agent are mixed according to the appropriate proportion to be evenly sprayed on a substrate with the thickness capable of covering the substrate, the amount roughly ranges from 80 g / m<2> to 90 g / m<2>, and if the required ground color needs to be shown in the crack in the decoration effect, the water-based color paste or the pearl powder or the gold aluminum powder can be added into the primer and the curing agent after the primer and the curing agent in the second step are mixed evenly; thirdly, after primer spraying, the water-based single-component finishing coat is sprayed in different time, different sizes of cracks can be obtained. The water-based crack lacquer construction technology has the advantages that a crack effect can be formed on the surface of the materials, the shorter the drying time of the double-component water-based crack primer is, the lower the drying degree becomes, and the thicker the produced cracks become. The larger the single-component water-based crack finish coating is, the larger the crack finish coating becomes, and the smaller the number of the cracks is.

Description

technical field [0001] The invention relates to a water-based crack paint coating construction process, which can be widely applied to the surfaces of solid wood and density board materials such as furniture, handicrafts and musical instruments. technical background [0002] At present, the crackle paint products are mostly solvent-based nitro. The crack principle is the irregular crack effect formed by the rapid drying and shrinkage of nitrocellulose and more powder in the nitro crackle paint. Different colors of crackle paint are matched with Substrate backgrounds of different colors and ingenious construction methods can form crack patterns with good ornamental value. However, nitro crack paint contains high VOC, uses nitrocellulose, and has poor environmental protection and safety performance. At present, the domestic water-based wood paint market has just started, the product system is not perfect, and the construction process is not perfect. The surface effect basical...
