Problems solved by technology

General ceramic glaze sintering requires high temperature, ordinary aluminum powder only has a melting point of 600°C, it is difficult to resist the high temperature of ceramic glaze sintering
It is difficult to obtain aluminum powder with a metallic decorative effect on the surface of ceramic porcelain, but the weather resistance of ordinary coatings on the surface of ceramics cannot meet the requirements of exterior wall decoration, and the adhesion and load-bearing are difficult to solve. It is difficult to obtain ordinary coatings with metallic decorative effects, which requires people to continue to study coatings for ceramic substrates, so that they can not only meet the weather resistance required for exterior wall decoration, but also meet the requirements of adhesion and load-bearing capacity

Abstract

The invention discloses a fluorocarbon aluminum paint for a ceramic substrate, which comprises a primer, a finish and a varnish, wherein the primer is prepared from the following raw materials in percentage by mass: 10-20% of PVDF (polyvinylidene fluoride) fluorocarbon resin, 7-10% of acrylic resin, 15-20% of filler, 45-55% of solvent and 3-5% of assistant; the finish is prepared from the following raw materials in percentage by mass: 20-25% of PVDF fluorocarbon resin, 10-15% of acrylic resin, 5-15% of pigment, 3-5% of aluminum powder and 50-60% of solvent; and the varnish is prepared from the following raw materials in percentage by mass: 30-40% of PVDF fluorocarbon resin, 10-20% of acrylic resin and 50-60% of solvent. The fluorocarbon aluminum paint can form a high-weather-resistance metal-effect coating on the ceramic substrate, thereby enriching the decorative effect of the ceramic surface and lowering the energy consumption for firing the ceramic glaze. The invention also discloses a manufacturing method of the fluorocarbon aluminum paint for a ceramic substrate.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a fluorocarbon aluminum powder paint for a ceramic base material and a manufacturing method thereof. Background technique [0002] As a decorative material, ceramics have higher and higher decorative requirements. As a decorative material for exterior walls, ceramics are required to have a metallic decorative effect. General ceramic glaze sintering requires high temperature, and ordinary aluminum powder has a melting point of only 600°C, so it is difficult to resist the high temperature of ceramic glaze sintering. It is difficult to obtain aluminum powder with a metallic decorative effect on the surface of ceramic porcelain, but the weather resistance of ordinary coatings on the surface of ceramics cannot meet the requirements of exterior wall decoration, and the adhesion and load-bearing are difficult to solve. It is difficult to obtain ordinary coatings with metal...
