Abstract

The invention belongs to the technical field of epoxy resin-based coating compositions, and particularly discloses a powder coating for building materials and a preparation method thereof, the powdercoating comprises the following raw materials in parts by mass: 40-62 parts of epoxy resin, 30-48 parts of polyester resin, 15-28 parts of polyether sulfone resin, 16-30 parts of a pigment, 8-18 partsof a filler, 0.5-1 part of a flatting agent and 4-12 parts of a curing agent, and the filler comprises nano clay, graphene, metal ceramic particles, nano silicon dioxide and carbon black. The powdercoating prepared by using the technical scheme is high in permeability and good in adhesive force, a continuous coating layer can be quickly formed during use, and the damage of the external corrosionmedium to the building materials can be effectively isolated. The formed coating layer can replace water on the surface of the building materials, and only cleaning of the water on the surface of thebuilding materials is needed when coating the coating, the humidity of the building materials does not need to be strictly controlled, the drying step before use is omitted, and the processing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of coating composition based on epoxy resin, and in particular relates to a powder coating for building materials and a preparation method thereof. Background technique [0002] Building materials are a general term for materials used in civil engineering and construction engineering, and can be divided into structural materials, decorative materials and some special materials. In order to prevent corrosion of building materials and prolong their service life, necessary protection is required. The current conventional method is to coat a layer of anti-corrosion coating on the surface of building materials to prevent external corrosive media from corroding the building materials. [0003] Powder coatings are often used in anticorrosion of building materials. Powder coatings are solid powder synthetic resin coatings composed of solid resins, pigments, fillers and additives. Unlike ordinary solvent-based coatin...
