Abstract

The invention provides a heat-resistant iron oxide green pigment, which is prepared from the following components in parts by mass: 10 to 15 parts of iron oxide yellow, 4.0 to 8.2 parts of sodium hydroxide, 10.0 to 12 parts of aluminum sulfate octadecahydrate, 0.70 to 1.2 parts of sodium hexametaphosphate, 0.50 to 2 parts of zinc chloride, 2.4 to 3.0 parts of aluminum chloride hexahydrate, 2.20 to 2.5 parts of sulfonated cobalt phthalocyanine and the balance of water.

Description

technical field [0001] The invention relates to a heat-resistant iron oxide green pigment and a synthesis method thereof, which can be used as a colorant in plastic processing, powder coating, and turf application. Background technique [0002] Globally, iron oxide is the second largest inorganic pigment after titanium dioxide and the largest colored inorganic pigment. Generally speaking, iron oxide colors include four types of iron oxide red, yellow, black and brown. Iron oxide green pigment is composed of iron yellow pigment and phthalocyanine blue pigment. It is a typical organic-inorganic composite pigment and can be used for coloring artificial turf, plastics, and coil steel coatings. According to reports, the current global consumption of iron oxide pigments is about 2 million tons, and the consumption amount can be close to 3 billion US dollars at most. [0003] Iron oxide yellow is iron oxyhydroxide, the chemical formula is usually α-FeOOH or α-Fe 2 O3·H 2 O is a...
