Abstract

The invention discloses an elastic metal shining coating and its preparation method, and belongs to the field of building materials. The coating is composed of a component 1 and a component 2 at the weight ratio of 6-10:1. The component 1 contains the following raw materials of: by weight, xylene, hexone, butyl acetate, propylene glycol methyl ether acetate, a fluorocarbon resin, aluminum paste, a dispersant, a leveling agent, an antifoaming agent, a scratch-resistance auxiliary agent and a polyester polyol resin. The component 2 is a curing agent. The combination of a fluorine-containing polymer and the elastic polyester resin in the coating endows the paint film with good elasticity, resistance to chemicals, non-adhesiveness, low friction and the like. Therefore, the coating provided by the invention is an elastic and persistant coating with excellent comprehensive properties. The raw materials of the coating are easily available. The coating requires a simple production method and convenient manual operation, accords with application requirements, has an extensive application prospect, and can be used for resisting fine cracks on exterior walls of buildings.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an elastic metal flash paint with elastic flash effect for exterior walls of modern urban buildings and external thermal insulation walls and a preparation method thereof. Background technique [0002] Since the early 1980s, fluorocarbon coatings cured at room temperature have been successfully developed. This easy-to-use coating has unparalleled weather resistance, chemical resistance, corrosion resistance, non-staining properties, water resistance, high hardness and Excellent properties such as high gloss. However, fluorocarbon metal paint itself has no elasticity, and the anti-cracking effect is not good. In recent years, conventional fluorocarbon metal paint has cracked on the insulation base surface with the cracking of the insulation base layer, causing serious cracking of the fluorocarbon metal paint film, which affects the appearance of the entire building.
