Method for painting ant wooden floor

Abstract

The invention provides a method for painting an ant wooden floor, and the method comprises the following steps: placing a standard ant wooden blank into a dry kiln, heating and humidifying the standard ant wooden blank, keeping a period of time after the temperature and humidity reach preset values, thereby degreasing the standard ant wooden blank and removing lapachol from the standard ant wooden blank; after maintaining the standard ant wooden blank which has a completely degreased surface and contains no lapachol in balancing manner for a period of time at room temperature, processing the standard ant wooden blank into an ant wooden floor native plate; painting a PU (polyurethane) waterborne primer on the ant wooden floor native plate and then naturally drying the waterborne primer; and finally, sequentially painting a UV (ultraviolet) primer, lacquer putty and UV finishing coat on the ant wooden floor native plate which is painted with the PU waterborne primer, thereby finishing the operation of painting the ant wooden floor. By using the method for paining the ant wooden floor, the purposes of degreasing, removing and blocking the grease and lapachol on the surface of the ant wooden floor are efficiently achieved, thereby enhancing the adhesive force of the painting on the surface and ensuring the apparent quality and the plate painting effect. Besides, the time for drying the painting is short and the production efficiency is high.

Description

technical field [0001] The invention relates to a painting process for wooden floors, in particular to a painting process for heavy ants wood floors. Background technique [0002] Before the popularity of Ipe wood flooring, it has always been the world of teak. Teak is a rare and valuable floor, but, after all, the price of teak floor cannot be afforded by the public. Therefore, many domestic businesses have been looking for a floor material that can replace it. In 1994, a kind of wood called Ipe wood (now commonly known as Brazilian "rosewood" wood) was finally discovered, which can meet the stability requirements of teak wood, and its hardness is higher than teak wood, so it can completely replace teak wood flooring. [0003] Ipe wood is produced in South America, the wood is hard and thick, and the air-dry density is 0.92 g / cm 3 ~1.16g / cm 3 , Anti-corrosion, anti-corrosion, strong anti-deformation, clear and beautiful color and texture, and changeable, pleasing to the...

Problems solved by technology

[0004] However, due to the heavy oiliness of Ipe wood, its wood ducts are rich in yellow chrysanthemum quinone, which seriously affects the paint adhesion and coating effect on the floor surface. The process of removing grease and chrysanthemum quinone in Ipe wood, so for the painting of Ipe wood, most of the current enterprises use oily two-component PU paint spray coating, although this can solve the problem of adhesion and coating effect problem, but the paint takes a long time to dry, which leads to low production efficiency, and it takes up a lot of space when it dries, so it is difficult to achieve mass production
