Paint to be Sprayed on the Surface of a Slim Tube-Shaped Bamboo Product and a Spraying Method Thereof

Abstract

A paint for spraying on bamboo products, such as on the exterior surface of a slim tube-shaped bamboo product, is a nonaqueous acrylic-based paint including 10 to 15 percent by weight of one or more flatting powders, 50 to 55 percent by weight of one or more acrylic resins, 1 to 5 percent by weight of one or more leveling agents, 13 to 16 percent by weight of one or more ester solvents, 10 to 15 percent by weight of one or more alcohol solvents, and 8 to 10 percent by weight of one or more ether solvents. After application of the wet paint composition, the solvents evaporate leaving a film of the acrylic resins, flatting powders, and leveling agents.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 
     
         1 . A method for painting a bamboo product, comprising:
 removing flock from the surface of the bamboo product to produce a smooth bamboo surface;   preparing a paint composition comprising 10 to 15 percent by weight of one or more flatting powders, 50 to 55 percent by weight of one or more acrylic resins, 1 to 5 percent by weight of one or more leveling agents, 13 to 16 percent by weight of one or more ester solvents, 10 to 15 percent by weight of one or more alcohol solvents, and 8 to 10 percent by weight of one or more ether solvents;   applying the paint composition on the surface of the bamboo product; and   drying the paint composition on the surface of the bamboo product.   
     
     
         2 . The method of  claim 1 , wherein the viscosity of the paint composition is approximately 20 cps. 
     
     
         3 . The method of  claim 1 , comprising spraying the paint composition on the bamboo product from an air gun at an air pressure of 0.45 Mpa. 
     
     
         4 . The method of  claim 1 , comprising drying the bamboo product after applying the paint for about 15 minutes at a temperature of about 70 to about 75 degrees Celsius. 
     
     
         5 . The method of  claim 4 , comprising applying a second coat of paint after the first coat has dried. 
     
     
         6 . The method of  claim 1 , wherein the bamboo product is rotated while the paint is applied at 3 to 5 revolutions per second. 
     
     
         7 . The method of  claim 1 , wherein the paint is applied on the surface of the bamboo product for 3 to 5 seconds. 
     
     
         8 . The method of  claim 1 , wherein the bamboo product is a slim tube-shaped bamboo product.
