Abstract
The invention discloses an anti-sedimentation agent for a coating, which comprises the following components in part by mass: 10 to 15 parts of organic bentonite, 20 to 30 parts of oxidized polyethylene with the molecular weight of 1,500 to 3,000 and 20 to 30 parts of hydrogenated castor oil. Preferably, the anti-sedimentation agent for the coating comprises 10 mass parts of organic bentonite, 25 mass parts of oxidized polyethylene with the molecular weight of 1,500 to 3,000 and 22 mass parts of hydrogenated castor oil. Along with the sedimentation of dyes, the anti-sedimentation agent for the coating is more and more intensity mixed with the dyes so as to improve the capability of keeping structures, and finally can stop the sedimentation; and the formed sediments are soft, incompact, and easy to redisperse.
Description
Technical field
The invention belongs to technical field of coatings, relate in particular to a kind of coating anti-sedimentation agent.
Background technology
In pigment particles suspended dispersed systems such as coating, printing-ink, tackiness agent, because the factors such as difference of specific gravity of liquid material and pigment particles, pigment often is in and is tending towards settled state, and coating often produces precipitation because of the pigment cohesion at container bottom between the shelf lives.Settlement separate, the caking of pigment be cause that dispersion system is inhomogeneous, the aberration of filming, grow dim, the reason of gloss difference etc., and be easy to generate the problem that some influence the coating strength performance.In order to prevent this settlement separate of pigment, can use anti-sedimentation agent according to different dispersion systems.
Summary of the invention
Goal of the invention:The object of the present invention is to provide a kind of coating anti-sedimentation agent, in order to adjust the internal structure that changes coating, as long as a small amount of interpolation can be played the effect of anti-settling.
Technical scheme:A kind of coating anti-sedimentation agent comprises in mass parts: 10 ~ 15 parts of organobentonites, 20 ~ 30 parts of the oxidic polyethylenes of molecular weight 1500 ~ 3000,20 ~ 30 parts of hydrogenated castor oils.Preferably: 10 parts of organobentonites, 25 parts of the oxidic polyethylenes of molecular weight 1500 ~ 3000,22 parts of hydrogenated castor oils.
Beneficial effect:Coating anti-sedimentation agent provided by the invention, along with the sedimentation of pigment, mutual getting together more is tending towards strongly, keeps structurized ability to strengthen, and sedimentation is stopped, the precipitation softness of this moment, loose, redispersion easily.
Embodiment
Embodiment 1.
Add 15 parts of anti-sedimentation agent in per 100 parts of coating, wherein organobentonite is 10 ~ 15 parts, 20 ~ 30 parts of the oxidic polyethylenes of molecular weight 1500 ~ 3000,20 ~ 30 parts of hydrogenated castor oils.Preferably: 10 parts of organobentonites, 25 parts of the oxidic polyethylenes of molecular weight 1500 ~ 3000,22 parts of hydrogenated castor oils.The coating that is added with anti-sedimentation agent did not have obvious sediment in 30 days, the flocks that is produced in 100 days can be eliminated by shaking up.
Claims (2)
1. a coating anti-sedimentation agent is characterized in that comprising in mass parts: 10 ~ 15 parts of organobentonites, 20 ~ 30 parts of the oxidic polyethylenes of molecular weight 1500 ~ 3000,20 ~ 30 parts of hydrogenated castor oils.
2. coating anti-sedimentation agent according to claim 1 is characterized in that comprising in mass parts: 10 parts of organobentonites, 25 parts of the oxidic polyethylenes of molecular weight 1500 ~ 3000,22 parts of hydrogenated castor oils.
