Bright modification anacardol ceramic dispersants have the advantages of versatile, dosage is small, effect is good, ceramic mud can be made to exist after use
In the case that water content is reduced as far as possible, reach the mobility of requirement again.The present invention also provides a kind of modified anacardol
The preparation method of ceramic dispersants.
To achieve these goals, the present invention uses following technical scheme：
A kind of preparation method of modified anacardol ceramic dispersants, is achieved by the steps of：
(1) toward unlatching stirring after addition anacardol, unsaturated organic amine and water in reactor, and heating is begun to warm up, treated
When temperature rises to 85~100 DEG C, formaldehyde is added, is reacted 1~3 hour after adding；
(2) sodium hypophosphite and unsaturated carboxylic acid and its salt are sequentially added, is stirred, treats that temperature rises to 80~120 DEG C
When, start that the initiator solution that mass percent concentration is 1~10% is added dropwise, this initiator solution is by the initiator and part
The water is formulated, and time for adding control temperature control at 1~3 hour, dropwise addition at 85~120 DEG C, drops after being added dropwise
Temperature discharging, produces the modified anacardol ceramic dispersants.
Further, the unsaturated organic amine is any one in diethylenetriamine, triethylene tetramine, TEPA
Kind is two or more with any mixture than mixing.
Further, the unsaturated carboxylic acid and its salt are acrylic acid, PAA, methacrylic acid and methacrylic acid
Any one in sodium or the two or more mixtures with any ratio mixing.
Further, the initiator be any one or two kinds in sodium peroxydisulfate, potassium peroxydisulfate and ammonium persulfate with
On with it is any than mixing mixture.
A kind of modified anacardol ceramic dispersants, the raw material components mainly matched by following portions by weight are made：
Compared with prior art, the present invention has following remarkable result：
1st, the functional group such as the ceramic dispersants carboxyl of the invention prepared, phosphate is identical with other conditions in addition
When, relative to other ceramic dispersants, there is good mobility and viscosity, reached energy-saving purpose, while to pottery
Porcelain biscuit has obvious enhancing effect.
2nd, ceramic dispersants simple production process, mild condition prepared by the present invention, production process charging, condition are all easy
Control, it is easy to accomplish industrialized production.
