Embodiment Construction

[0029] The principle of the present invention is that the composition and addition amount of the nano-flame retardant dispersion have been studied, and strong dehydrating substances are produced under combustion conditions, so that the nano-filled coating is rapidly carbonized and is not easy to produce flammable volatiles, thereby preventing the flame from spreading; A protective film is formed on the surface of combustibles to isolate oxygen and prevent further combustion; the concentration of combustible polymers is reduced, and the moisture released from dehydration dilutes the concentrations of combustible gases and oxygen, effectively realizing flame retardancy. Specifically, it includes research on the selection of raw materials, assisting in the formation of flame-retardant coatings, and the use of aluminum hydroxide and boehmite to form transparent coatings after nano-particle treatment, so that the paint has good transparency, good water resistance, and high hardness a...

Abstract

The invention relates to a transparent flame-retardant aqueous nanometer coating for woodenware, and a production method thereof. Production raw materials comprise, by mass, 35-50% of an aqueous acrylic emulsion, 0-15% of aqueous polyurethane, 5-10% of a nanometer aluminum hydroxide flame retardation dispersion, and 5-10% of a nanometer boehmite dispersion. Aluminum hydroxide and boehmite are added after treatment of nanoparticles to form a transparent coat layer, so the transparent coating has the advantages of effectively improved flame retardation property, simple preparation and easy enforcement. The coating provided by the invention has the characteristics of protruding transparency, compatibility and environmental protection performance, excellent contamination resistance, strong adhesion, good sanding property, no activation period, few organic volatile matters, good fullness and good storage stability.

Description

technical field [0001] The invention relates to IPC international patent classification C09D coating composition water-based wood coating technology, in particular to a transparent nano flame-retardant water-based coating for wood and a production method thereof. Background technique [0002] Wood paint refers to a type of resin paint used on wood products, including polyester, polyurethane paint, etc., which can be divided into water-based and oil-based. According to gloss, it can be divided into high gloss, semi-matte and matte. According to the application, it can be divided into furniture paint, floor paint and so on. Water-based wood coating is a coating product applied on the surface of wooden furniture or wood products. In addition to having a protective effect on wood products, it also needs to have a certain decorative effect. In the coating process of water-based wood coatings, the American coating process occupies a very important position. American-style coati...
