Embodiment Construction

[0023] The present invention is described further below, and preferred embodiment of the present invention is: the three-dimensional three-dimensional wood grain spraying process that is used for profile surface described in this embodiment comprises the following steps:

[0024] The first step: decontamination and cleaning the surface of the profile;

[0025] The second step: drying the cleaned profile surface;

[0026] The third step: spraying the first layer of matte polyester powder on the surface of the profile; the main component of the matte polyester powder is 200-mesh solid powder produced by grinding solid resin and inorganic ceramic raw materials. Then through the electrostatic spraying of the fully automatic horizontal spraying production line, the matte polyester powder is evenly covered on the surface of the profile.

[0027] Step 4: Bake the first-coated profile at 120°C for 15 minutes to make the matte polyester powder on the surface of the profile into a gell...

Abstract

The invention provides a process for spraying three-dimensional wood grain. The process comprises the following steps that: base powder is sprayed on a section for the first time; wood grain is transferred to the section for the second time; a wood grain pattern board of which the wood grain effect is the same as that generated by the second step is produced by computer operation; high-light-saturation polyester solid powder is vertically sprayed on the surface of a product by using a laser beam to enable the powder to generate concave-convex three-dimensional wood grain effect on the surfaceof the section; and after the section is baked at the temperature of 200 DEG C for 30 minutes, the quality of the powder on the surface is changed, the surface of the product is covered with a transparent layer of which the hardness reaches 7-8H on the premise of ensuring unchanged wood grain effect. When the hardness of a coating on the surface of the section reaches 7-8H, the abrasive resistance of the section is further improved, and the surface of the section has rich wood grain, brilliant colors, vivid wooden feeling and three-dimensional feeling; and as the surface of the section is completely covered by a complete transparent coating, the wood grain effect on the section lasts longer and is more durable.

Description

Technical field: [0001] The invention relates to the technical field of profile surface treatment, in particular to a three-dimensional wood grain spraying process for aluminum profiles. Background technique: [0002] In the building materials industry, wooden building materials are popular for their superior decoration and unique wood grain texture. However, after the use of wood-based combustible organic boards is restricted, the building materials market generally replaces fluorocarbon aluminum veneers and aluminum profiles. Wooden panels are used as curtain wall materials, but the colors of fluorocarbon aluminum veneers and aluminum profiles are monotonous, which cannot show the unique texture and color of wood materials, and the service life of fluorocarbon aluminum veneers is short. Invention content: [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a wood grain spraying process for profiles with strong three-...
