Description
Technical field
The invention belongs to ink-jet ink technology of preparing and high molecular polymer field, and in particular to a kind of acrylate-the third
Acrylamide block polymer and its synthetic method and application.
Background technology
Ceramic ink jet printing technology is the most top technology in present ceramic surface decoration technique field, is by ceramic paint powder
System is directly printed on stock it by ink-jet printer into ceramic ink, is molded through high-temperature process.Due to this system
The geometry of the incrustation that Preparation Method is carried out is the plastic complicated shape product by computer software control, and is departed from
Mould limitation, therefore can greatly shorten the mechanical process of other mode of printings.Due to its particularity, inkjet printing is realized
Key be ceramic ink preparation.
Ceramic ink is generally made up of ceramic paint particle, solvent, dispersant and other auxiliary agents, and ceramic paint particle is ink
The core substance of water, in order to ensure the dispersion stabilization of paint ink, reduces the operating troubles such as plug nozzle, usually requires that pigment
The particle diameter of particle is less than 1 μm, and dispersant can ensure the dispersion that ceramic paint powder can be uniform and stable in a solvent, is come with this
Ensure that the ceramic ink for preparing was not reunited before spraying.As can be seen here, stably dispersing of the dispersant to ceramic ink
Property plays decisive role.
Effect of the dispersant to ceramic pigment is mainly realized by following three kinds of modes：
(1) electrostatic stabilization is theoretical：Increase the absolute value of ceramic pigment particle surface current potential, improve intergranular electrostatic stabilization
Effect；(2) spatial stability is theoretical：By steric hindrance of the macromolecule dispersing agent between the adsorption layer that ceramic pigment particle surface is formed
Effect, makes to produce very strong steric hindrance repulsive force between particle；(3) regulate and control ceramic pigment particle surface polarity, both strengthen decentralized medium
To its wetability, surface solvent film is enhanced again, improve grain surface texture degree, make structuring repulsive force significantly
Enhancing.
Dispersant can effectively prevent the coagulation of ceramic ink, and its reasonable selection and content are crucial.
Macromolecule dispersing agent is the efficient polymeric dispersant of a class, due to its excellent performance, is led in ink and coating
Vital effect is played in domain.Compared with traditional dispersant, macromolecule dispersing agent can accelerate surface of pigments wetting, shorten
The time required to grinding, ink viscosity is reduced, the tinctorial strength of ink or coating can also be increased, increase the solid content of system, most
It is important that being also may rely on its powerful solid space effect, dispersion stabilization of the pigment in organic media is improved.Block is high
Compared with random copolymer dispersant, the former has preferably moistening peptizaiton to granules of pigments to dispersal agent molecule；And block is combed
Type copolymer dispersant has more preferable absorption stability, dispersion stabilization than simple block copolymer dispersant.
The research such as Zhou Songqing finds that with polyvinyl alcohol as dispersant the addition of dispersant is 0.1%, and shitosan is bonding
Agent, when addition is 0.08%, the stability and other physicochemical properties of the black ceramic ink of preparation are optimal；
The macromolecule dispersing agent PMAA-mPEO of the synthesis such as Yoshikawa, research display, to BaTiO3Suspended substance has good dispersion
Stability.
Mainly there are ICI, KvK, Dupont, BASF, BYK in external exploitation at present, the company of development macromolecule dispersing agent,
The companies such as Daniel, SunChemical.The domestic research to macromolecule dispersing agent is started late, and dispersant is few, synthesis side
Method is also immature, and the product performance of its exploitation cannot also fully meet use requirement, still need to a large amount of import external products.Cause
This, the macromolecule dispersing agent of exploitation and development function admirable is significant
