Sandalwood type solid wood grain spraying process

Abstract

The invention provides a sandalwood type solid wood grain spraying process. The process comprises the following steps of: performing cleaning and drying treatment on the surface of a sprayed piece; spraying saturated polyester powder on the surface of the sprayed piece for the first time; baking the sprayed piece at the moderate temperature of 120 DEG C for 15min, so that the polyester powder forms gel on the surface of the sprayed piece; cooling the sprayed piece; spraying sandalwood type resin powder on the cooled sprayed piece for the second time; baking the sprayed piece at the temperature of 150 DEG C for 25min after spraying is finished, so that the secondarily-sprayed powder is fully combined with the primarily-sprayed powder; cooling again; spraying a layer of saturated resin powder on the sprayed piece by utilizing computer programming or a scanned wood grain plate; baking the sprayed piece at the high temperature of 200 DEG C for 30min; and fully fusing the coatings on the surface of the sprayed piece, so that the coatings are disorderly and firmly adhered to the surface of the sprayed piece, and cooling the sprayed piece. The sprayed piece characterized by strong three-dimensional sense, capability of naturally giving out sandalwood fragrance, ultra-low surface tension, and super properties of no pulverization, no fading, fraction resistance, impact resistance and the like is obtained.

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 purpose of the present invention is to overcome the deficiencies of the prior art and provide a wood grain spraying process with a strong three-dimensional...
