Technical field

The present invention relates to iron oxide blue field, is exactly a kind of coated fire-retardant iron oxide blue.

Background technology

Iron oxide blue is navy blue and light blue powder, lovely luster, and strong coloring force, covering power is slightly poor. Opaque is harder. Quality standard: tinting strength, tinting power 95 ~ 105% oil absorption 15-30% moisture content 1.0%, residue on sieve (200 mesh sieve)≤1.0%, the hydrotrope 1.0%.

Summary of the invention

The object of the present invention is to provide a kind of coated fire-retardant iron oxide blue

Above-mentioned purpose realizes by following scheme:

A kind of coated fire-retardant iron oxide blue, it is characterized in that: it is to be made by the raw material of following weight parts: iron oxide blue 250-300, coated fire-retardant aluminium hydroxide 10-20, the poly-high containing hydrogen silicone oil 2-4 of trimethyldihydroquinoline 2-4, acetone 10-15., cocoanut fatty acid diethanolamide 0.3-0.4, silane coupler a1712-4, decabromodiphenyl ethane 1-2, alcohol ether glucoside 0.5-0.8, laureth sodium sulfovinate 0.2-0.4, zinc sulphide 0.1-0.2.

The coated fire-retardant iron oxide blue of described one, is characterized in that: preparation method comprises the following steps:

(1) get by weight aluminium hydroxide, add again the titanate coupling agent TMC-201 that is equivalent to aluminium hydroxide weight 0.4-0.8%, the epoxy linseed oil of 1.3-1.5%, the aluminium oxide of 0.4-0.5%, and appropriate amount of deionized water, under 1000-1200rpm, after high speed shear 10-15 minute, take out, dry, must be coated fire-retardant aluminium hydroxide for subsequent use;

(2) will except iron oxide blue, mix by weight by all the other raw materials, add appropriate amount of deionized water, after stirring, obtain modification liquid for subsequent use;

(3) modification liquid and iron oxide blue are mixed by weight, high speed shear 20-30 minute under 800-1000rpm, takes out, and dries, and gained powder utilizes roller milling machine to carry out wet-milling, and wet grinding media is absolute ethyl alcohol, and mill ball is sintered carbide ball;

(4) by the slurry vacuum drying after gained wet-milling and get final product.

Beneficial effect of the present invention is: the present invention has fire-retardant, acid and alkali-resistance, uvioresistant, chemical solvent resistance. Coated fire-retardant aluminium hydroxide, by modification, has increased its flame retardant effect, and itself and iron oxide blue can combine more closely.

Detailed description of the invention

A kind of coated fire-retardant iron oxide blue, it is to be made by the raw material of following weight parts (kg): iron oxide blue 300, coated fire-retardant aluminium hydroxide 20, poly-trimethyldihydroquinoline 4, the high containing hydrogen silicone oil 4 of acetone 15., cocoanut fatty acid diethanolamide 0.3, silane coupler a1714, decabromodiphenyl ethane 2, alcohol ether glucoside 0.8, laureth sodium sulfovinate 0.4, zinc sulphide 0.2.

The coated fire-retardant iron oxide blue of described one, preparation method comprises the following steps:

(1) get by weight aluminium hydroxide, add again the titanate coupling agent TMC-201 that is equivalent to aluminium hydroxide weight 0.8%, 1.5% epoxy linseed oil, 0.5% aluminium oxide, and appropriate amount of deionized water, under 1200rpm, high speed shear, after 15 minutes, is taken out, dry, must be coated fire-retardant aluminium hydroxide for subsequent use;

(2) will except iron oxide blue, mix by weight by all the other raw materials, add appropriate amount of deionized water, after stirring, obtain modification liquid for subsequent use;

(3) modification liquid and iron oxide blue are mixed by weight, high speed shear 25 minutes under 800rpm, takes out, and dries, and gained powder utilizes roller milling machine to carry out wet-milling, and wet grinding media is absolute ethyl alcohol, and mill ball is sintered carbide ball;

(4) by the slurry vacuum drying after gained wet-milling and get final product.

Iron oxide blue properties of product that the present embodiment is produced are analyzed data as following table:

Project	Index	Testing result
			105 DEG C of volatile matters (%)	≤1.0	0.82
Oil absorption (%)	15-25	21.9
			Tinctorial strength (%)	95-105	98.7
Resistance to 200 DEG C/30min (△ E)	≤1.0	0.83
