Abstract

The invention discloses an outdoor high-performance fluorocarbon coating which comprises the following components in percentage by weight: 40-60% of a water-based fluorocarbon emulsion, 1-3% of a dispersing agent, 0.6-2% of a defoaming agent, 15-30% of pigment filler, 0.3-1 part of a wetting agent, 0.1-1% of a flatting agent, 0.1-1% of a sterilizing agent, 0.3-2% of a thickening agent and the balance of water; the thickening agent comprises a Tego 3010 and a Tego 3030; the mass ratio of the Tego 3010 to the Tego 3030 is 1: (1-6). The water-based fluorocarbon coating integrates the environmental protection of water-based paint and the high performance of fluorocarbon paint, has the advantages of excellent durability, easy constructability, cleanness and long-term excellent gloss retention and color retention, and meanwhile, water is used as a solvent, so that the risk of fire disasters during construction is eliminated, and the atmospheric pollution and the injury to constructors are reduced. Compared with the prior art, the outdoor high-performance fluorocarbon coating has better adhesive force and is more beneficial to popularization and application.

Description

technical field [0001] The invention belongs to the technical field of water-based coatings, and in particular relates to an outdoor high-performance fluorocarbon coating and a preparation method thereof. Background technique [0002] Fluorine resin refers to a polymer compound containing fluorine atoms on the carbon atoms of the main chain or side chain, and polyvinylidene fluoride resin (PVDF) is the resin matrix for preparing PVDF fluorocarbon coatings. The fluorine-carbon bond formed by fluorine, the most electronegative element, has superior firmness and symmetry, making PVDF fluorocarbon coatings have excellent properties: chemical corrosion resistance, oxidation resistance, high mechanical strength and toughness, and excellent weather resistance It has been widely used in the field of construction. [0003] However, traditional PVDF coatings are mostly organic solvent-based coatings and powder coatings. Organic solvent-based PVDF fluorocarbon coatings will volatilize...
