Problems solved by technology

When the traditional oil-based paint is exposed to the sun for a long time, it is easy to cause the paint film to fall off and differentiate due to sun and rain, thus losing its protective effect. Frost resistance and other aspects do not meet the requirements. At present, there is a lack of a special paint for wooden windows with excellent performance and long-lasting protection of the board on the market.

Abstract

The invention belongs to the technical field of wood coatings, and particularly relates to a special water-based varnish for outdoor wooden windows and a preparation method thereof. The special water-based varnish comprises the following components in parts by weight: water-based resin, a pH regulator, an antifoaming agent, a film-forming solvent, a wetting agent, a leveling agent, an antioxidant,a light stabilizer, a flatting agent, a preservative, a thickener and deionized water. In addition, the invention further provides specific preparation process steps of the special water-based varnish for the outdoor wooden windows. The special water-based varnish for the outdoor wooden windows has excellent anti-aging and anti-pulverization functions, good weather resistance and excellent adhesive force, water resistance and freezing resistance, and can be used for effectively protecting wood for a long time and prolonging the service life; the water-based varnish product obtained by the preparation method provided by the invention can achieve almost zero microbubbles in a tank, and the product prepared according to the process can achieve thick coating without bubbling in field construction.

Description

technical field [0001] The invention belongs to the technical field of wood coatings, and in particular relates to a special water-based clear finish paint for outdoor wooden windows and a preparation method thereof. Background technique [0002] The wooden window system comes from Germany and has gradually developed in China in recent years. The wooden window is retro and elegant, natural and beautiful, practical and decorative at the same time. At present, the most popular ones on the market are aluminum-clad wood or wood-clad aluminum. The wood used is mainly pure solid pine, oak, and oak. Because it is exposed to the outdoors all the year round, the board needs to be protected by coating, and a layer of paint is applied on the surface of the board. , for the protection and decoration of wooden windows. When the traditional oil-based paint is exposed to the sun for a long time, it is easy to cause the paint film to fall off and differentiate due to sun and rain, thus los...
