A kind of heat-resistant iron oxide green pigment and its synthesis method

Abstract

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

Description

A kind of heat-resistant iron oxide green pigment and synthesis method thereof technical field The present invention relates to a kind of heat-resistant iron oxide green pigment and synthetic method thereof, can be used in plastic processing, powder coating, human Used as a colorant in common lawn applications. Background technique On a global scale, iron oxide is the second largest inorganic pigment after titanium dioxide, and also the largest colored inorganic pigment. material. In general, iron oxide-based colors include iron oxide red, yellow, black and brown. Iron oxide green pigment is composed of iron yellow pigment and phthalo It is a typical organic-inorganic composite pigment, which can be used in artificial turf, plastic, coil coating, etc. Coloring used. According to reports, the current global consumption of iron oxide pigments is about 2 million tons, and the consumption can reach up to Nearly $3 billion. Iron oxide yellow (Iron oxide yellow) is ...
