Water-thinned Normal temperature hardening fluorosilicious paint with metal texture

Abstract

The water-thinned normal temperature hardening fluorosilicious paint with metal texture is mainly used in painting inner and outer wall in building and may be used in painting concrete, gypsum board, lignocellulose board and metal in order fields. It consists of water-thinned fluorocarbon emulsion, self-crosslinked organosilicon modified acrylic acid emulsion and acrylic acid emulsion as filming and adhering material, and pigments as supplementary material to produce metal texture. The water-thinned resin combination of the present invention has excellent weather resistance, strong pollution resistance, high air permeability, VOC value near zero and other advantages. The nano transparent ferric oxide system pigment and mica pigment combinatino produces metal texture and rich color.

Description

technical field [0001] The water-based room-temperature curing fluorosilicon metal texture coating of the invention relates to a coating material, which is mainly applied to the coating of interior and exterior walls of buildings, and can also be applied to the coating of concrete, gypsum boards, wood fiber boards and metals. Background technique [0002] The existing metal texture coatings are mainly solvent-based products, including fluorocarbon resin coatings that are baked at high temperature and formed into films, which can only be used for the coating of factory-made metal curtain wall panels, and the color is monotonous and expensive; It is made of type and room temperature curing resin, usually called metallic flash paint, which is also mostly used for metal or small handicraft coating. Its high flash gloss is difficult to adapt to large-area architectural coating, and the coating film has poor air permeability. The finishing coating of the building wall is easy to p...

[0002] The existing metal texture coatings are mainly solvent-based products, including fluorocarbon resin coatings that are baked at high temperature and formed into films, which can only be used for the coating of factory-made metal curtain wall panels, and the color is monotonous and expensive; It is made of type and room temperature curing resin, usually called metallic flash paint, which is also mostly used for metal or small handicraft coating. Its high flash gloss is difficult to adapt to large-area architectural coating, and the coating film has poor air permeability. The finishing coating on the building wall is easy to peel and peel off. The solvent used in the preparation is large, and the toxic solvent volatilizes and pollutes the environment, endangering organisms and affecting human health.

It is generally accepted that the development direction of architectural coatings is water-based, but pigments that usually obtain metallic textures, such as aluminum silver powder, copper gold powder, etc., are prone to chemical reactions under the action of water-based media due to their metal activity, and are oxidized, discolored, darkened, and lost. Metallic texture, so the development and research of water-based metallic texture coating products with practical application value are still in progress
