High-performance, environmentally friendly inorganic pigments for fluorocarbon coatings

Business Club, September 19th Abstract: This article describes the inorganic pigments used in fluorocarbon coatings. It focuses on the performance, characteristics, types, and applications of environmentally friendly color-mixed inorganic pigments. It also analyzes the development status of these pigments and allows domestic fluorine to be used. Carbon paint manufacturers have further understanding of the application of high-performance, environmentally friendly inorganic pigments in high-grade coatings.

1. Overview Among all kinds of coatings, fluorocarbon coatings have high electronegativity due to the introduction of fluorine, strong carbon-fluorine bonds, and exceptional properties such as weather resistance, heat resistance, low temperature resistance, and chemical resistance. , And has a unique non-sticky and low friction. After decades of rapid development, fluorine coatings have been widely used in various fields such as construction, chemical industry, electrical and electronics industry, machinery industry, aerospace industry and household products. It has become the highest overall coating brand after high-performance coatings such as acrylic coatings, polyurethane coatings, and silicone coatings.

The pigment in the fluorocarbon coating composition is an important component of the fluorocarbon coating, giving the coating a brilliant color. These pigments must also have excellent weathering resistance, heat resistance, low temperature resistance, and chemical resistance. Wait.

Environmentally-friendly color-mixed inorganic pigment belongs to this kind of pigment. It is a non-toxic, high-performance inorganic pigment produced from a variety of metal oxides through high-temperature solid-state reaction. Therefore, some domestic scholars also call it metal oxide miscible phase. Pigments, in the international community, often call CICP, MMO pigments, due to the general reflection infrared function, in the fluorocarbon coating applications can play the role of insulation and cooling, which is also called "cool" paint.

Environmentally-friendly color-mixed inorganic pigments were first developed by Hunan Jufa Technology Co., Ltd. and were first introduced in the market last year as high-grade colored inorganic pigments. It is the highest among all pigments and dyes, and it is very suitable for fluorocarbon coatings, The application of high-grade coatings such as color steel coatings has eased the problem that the fluorocarbon coating industry often faced with pigments with high weather resistance was relatively rare and the types of colors that appeared were very limited.

2. Commonly used varieties of inorganic pigments for fluorocarbon coatings, so-called pigments, refer to substances that can color objects. Pigments are soluble and insoluble, inorganic and organic. Inorganic pigments are divided into natural inorganic pigments and synthetic inorganic pigments. Naturally produced inorganic pigments are entirely derived from mineral resources such as natural cinnabar, red clay, and realgar. Synthetic inorganic pigments are inorganic pigments synthesized by chemical reactions, such as titanium dioxide, titanium nickel yellow, titanium chromium brown, cobalt blue, cobalt green, copper chromium black, cadmium red, cadmium yellow, chromium yellow, iron blue, and lithopone , carbon black, red iron oxide, yellow iron oxide, etc.

The vast majority of inorganic pigments for fluorocarbon coatings are synthetic inorganic pigments, mainly titanium pigments, metal oxide phase-mixed pigments (MMO), iron oxide pigments, and lead-cadmium pigments. With the development of people’s aesthetic concepts and environmental protection concepts, the color of inorganic pigments has become increasingly beautiful, bright, and the performance has become increasingly high-quality, and products have become increasingly low-carbon and environmentally friendly.
