Abstract
The invention discloses a kind of Graphene modification mill base material, this Graphene modification mill base material is made up of the component comprising following weight part: ethyl propenoate 20-40 part, glycidyl acrylate 10-25 part, dimethyl ether 10-20 part, Graphene 10-15 part, amylopectin 3-12 part, maleic anhydride inoculated polypropylene 5-12 part, n-octyl-isothiazolin ketone 0.8-2 part and carbon black 0.8-1.5 part.The Graphene modification mill base material obtained by present method not only has good dispersion effect, and has good sticking power.
Description
Technical field
The invention belongs to mill base Material Field, particularly a kind of Graphene modification mill base material and preparation method thereof.
Background technology
In the process used, often there is the problem of consistency, usually also can solve the compatibility problem of mill base and coating by adding auxiliary agent, but in general, can not reach and separate flocculation completely in mill base.The solution flocculating degree of the mill base of superperformance is higher, so just can have good particle uniformity, good tinting strength and storage stability.Due to the otherness of composition in pigment in mill base and base-material, thus can cause the uneven distribution of mill base, make the product after mill base film forming occur coming off and cleavage phenomenon because of the change of the factor such as ambient temperature and humidity.If mill base dispersing property is good, then the generation can avoided loose colour He grow dim.The quality of the dispersiveness of another coating self also directly affects the loose colour of colored paint and grows dim.
Acrylate materials has good ozone resistants, resistance to air loss, resistance toly to subdue and resistance to breach growth property, and uvioresistant discolouration etc., but simultaneously acrylate materials also exists the shortcomings such as tack difference and low temperature become fragile, and causes its use to receive a lot of restriction.
Summary of the invention
For above-mentioned demand, the object of this invention is to provide a kind of Graphene modification mill base material and preparation method thereof, the mill base material obtained by present method not only has good dispersion effect, and has good sticking power.
Object of the present invention can be achieved through the following technical solutions:
A kind of Graphene modification mill base material, be made up of the component comprising following weight part:
Ethyl propenoate 20-40 part,
Glycidyl acrylate 10-25 part,
Dimethyl ether 10-20 part,
Graphene 10-15 part,
Amylopectin 3-12 part,
Maleic anhydride inoculated polypropylene 5-12 part,
N-octyl-isothiazolin ketone 0.8-2 part,
Carbon black 0.8-1.5 part.
The percentage of grafting of described amylopectin is 30-50%.
The percentage of grafting of described maleic anhydride inoculated polypropylene is 25%.
A preparation method for Graphene modification mill base material, the method comprises the following steps:
(1) ethyl propenoate 20-40 part, glycidyl acrylate 10-25 part, dimethyl ether 10-20 part, amylopectin 3-12 part, maleic anhydride inoculated polypropylene 5-12 part and n-octyl-isothiazolin ketone 0.8-2 part is taken, add in clarifixator, at 50-80 DEG C, mix 1-3 hour, obtain a homogeneous mixture;
(2) mixture of step 1 is added Graphene 10-15 part and carbon black 0.8-1.5 part under with the agitation condition of 600-800 rev/min of rotating speed, mix;
(3) 1M sodium carbonate adjust ph will be added in above-mentioned mixed solution to 8-8.5, deaeration 1 hour in vacuum defoamation machine, obtain Graphene modification mill base material.
PH value in described step 3 is 8.2.
Compared with prior art, its beneficial effect is: in the present invention in the present invention, owing to adding Graphene, makes mill base have preferably evenly performance, improves the tack of mill base simultaneously.Present invention adds amylopectin and coordinate with certain temperature, make the mill base obtained not only have the weather resistance of ethyl propenoate, while there is good tack, there is good dispersiveness simultaneously, thus can be used as the surface spraying mill base of less article, such as stationery, toy etc.
