Abstract
The invention provides a special mimic lead chromate yellow pigment used in rubber and plastic industries and a preparation method thereof. The pigment comprises the following components in percentage by weight: 9 to 35 percent of azo pigment, 0 to 10 percent of white pigment and 60 to 91 percent of inert pigment. The mimic lead chromate yellow pigment is a lead-free chromium-free environment-friendly product, and the light fastness, heat resistance, acid resistance and alkali resistance of the pigment are obviously better than those of lead chromate yellow pigments. Due to adopting lead-free and chromium-free raw materials, the preparation method solves the problem of waste liquid pollution caused by toxic harmful ion during the preparation of the lead chromate yellow pigment.
Description
Technical field
The present invention relates to a kind of pigment and preparation method, be specifically related to a kind of pigment of unleaded, Chrome-free.
Background technology
Plumbous chromium series yellow ultramarine is produced existing more than 80 year history in China, lead-chrome yellow pigment is a kind of Yellow organic dye of bright-coloured color, and strong covering power, anti-solvent, heat-resisting, cheap, advantage such as turnout is big are arranged and is subjected to the welcome of coatings industry, rubber plastic industry deeply.
Plumbous chromium series yellow ultramarine is owing to be to make lead-chrome yellow pigment with water miscible lead salt and water miscible chromic salt, so the liquid waste disposal leaded, that contain chromium ion in the making processes is a serious problem.
Play European Union in July, 2006 and forbid that leaded, chromium, cadmium, the plastics of mercury, electronic product enter Europe.The whole world will enter pigment and some harmful solvent slops that forbidding contains " plumbous chromium " in 2008.Therefore from environmental angle, to the protection HUMAN HEALTH, it is extremely urgent that a kind of yellow ultramarine of cheapness of unleaded Chrome-free replaces plumbous chromium series yellow ultramarine, is the needs in market.
