Description
Technical field
The present invention relates to a kind of surface-modified pigments and contain the aqueous color paste of the surface-modified pigments, more particularly to a kind of
Natural emulsion monoazo pigment, aqueous color paste and the preparation method that surface is modified, belong to technical field of fine.
Background technology
Natural emulsion is a kind of essential industry raw material obtained by being acquired in the natural plants such as rubber tree, the characteristics of composition
It is made of rubber hydrocarbon and nonrubber hydrocarbon, rubber hydrocarbon is mainly polyisoprene rather than rubber hydrocarbon by protein, lipoid, carbohydrate
With the compositions such as inorganic matter, nonrubber hydrocarbon is coated with around rubber hydrocarbon and forms stable mixed system.It is main former with natural emulsion
Expect the natural latex products such as the emgloves, balloon, the rubber band that are prepared through techniques such as dipping, overturning, rinsing and drying, tool
Have mite-proofing and antimicrobial, super-elastic, can the series of advantages such as natural degradation, be widely applied in fields such as toy, health.
Pigment stabilizer is dispersed in the aqueous color paste formed in water-based system, is the natural latex products systems such as gloves, balloon
Common colorant during standby.Azo pigments is common pigment in a kind of latex product, contains azo group (- N in molecule
=N-), azo pigments is first usually fabricated to aqueous color paste when in use, the aqueous color paste is added to glue before latex impregnation
It in breast and stirs evenly, then forms finished product by processes such as dipping, overturning, rinsing and drying.But due to monoazo pigment
Relative molecular weight is smaller and other reasons, and the resistance to migration of monoazo pigment is poor, in the manufacturing process of product and after the completion
The case where tending to occur color transfer.Such as during producing emgloves, color transfer can influence other colors when diafiltration
The migration of the production of gloves, finished commodities color can cause other products to have pollution, the color on especially red product frequent
On the product for moving to yellow or white.
Report the method being largely modified about surface of pigments both at home and abroad：The Chinese patent of Publication No. CN105713237
A kind of preparation method of natural emulsion high glaze environmental protection organic pigment mill base is disclosed, by organic pigment, wetting dispersing agent, increasing
The groups such as photo etching, moisturizer are grouped as；Authorization Notice No. is that the Chinese patent of CN102604447 discloses a kind of phosphorous chemical combination of use
Object carries out surface modification, the method to improve aqueous color paste tinting strength, tinting power and stability to pigment such as titanium white, iron oxide, phthalocyanines；It is public
The pigment that a kind of surface of U.S. Patent Publication that the number of opening is US5837045 is modified, containing being connected directly between pigment on the pigment
The ion or nonionic base of aromatic radical, carbonic acid or the sulfuric acid on surface etc. and its salt；The United States Patent (USP) of Publication No. US6120596 is public
A kind of method that surface modification being carried out to pigment using halogen-containing silane compound is opened, this method can promote granules of pigments
Dispersion effect, reduction particle diameter distribution in mill base.
However, since color transfer is not only with pigment itself close relation, also have one with used system environment
Fixed effect, when such as use is in natural rubber system, the latex of different states of cure (vulcanization) and the product colour of different process it is resistance to
Migration is also different, so in relevant report and scheme, has no and well solves monoazo in natural latex products
The technical solution of pigment colour migration.
Invention content
In order to solve the above technical problems, the present invention provides natural emulsion monoazo pigment, water that a kind of surface is modified
Property mill base and preparation method, carrying out targetedly surface to monoazo pigment according to the compositing characteristic of natural emulsion is modified, at
