Description
Technical field
The invention belongs to centrifuge technique fields, and in particular to a kind of centrifuge centrifugal drum inner-wall paint.
Background technique
Centrifuge is exactly to make that different material to be separated is needed to obtain accelerating isolated machine using centrifugal force.Centrifuge is big
Amount is applied to the fields such as chemical industry, food, pharmacy.It is broadly divided into perforated wall centrifuge and sedimentation-type centrifuge two major classes.Filtering
The cardinal principle of formula centrifuge is the centrifugal force (cooperating filter material appropriate) generated by the centrifugal drum to run at high speed, will be centrifuged
Liquid phase acceleration in solid-liquid mixed liquor in roller throws away centrifugal drum, and solid phase is stayed in centrifugal drum, and it is solid to reach separation
The effect of body and liquid, or it is commonly called as the effect of dehydration.In pharmaceutical field, various liquid phase drugs in centrifugal work, to from
Heart inner wall of rotary drum time of contact is long, and friction impact force is big, and in the prior art to the corrosion resistance of centrifugal drum inner-wall paint and
Crocking resistance is limited, and after centrifuge works long hours, the phenomenon that Paint Falling, Paint Falling easily occurs in centrifugal drum inner wall
It is admixed together with liquid phase drug afterwards, its quality of strong influence.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of centrifuge centrifugal drum inner-wall paint is provided.
The present invention is achieved by the following technical solutions:
A kind of centrifuge centrifugal drum inner-wall paint, including organic solvent, adjuvant component further include following parts by weight group
Point: 1009 18-42 of epoxy resin, 3175 3-8 of blocked isocyanate, fluorine carbon emulsion 10-20, nanometer sericite composite particles

Further, the epoxide equivalent 2100-2200g/eq of the epoxy resin 1009.
Further, deblocking temperature≤165 DEG C of the blocked isocyanate 3175.
Further, the organic solvent is the combination of one or both of n-butanol, propylene glycol monomethyl ether, described organic molten
It is 40-80 that parts by weight are added in agent.
Further, the auxiliary agent is coalescing agent, and the coalescing agent is Lauryl Alcohol ester, and the auxiliary agent adds weight
Part is 0.5-0.8.
Further, the nanometer sericite composite particles are the preparation method comprises the following steps: a certain amount of nanometer of sericite is mixed with water
It closes and is configured to the nanometer sericite water slurry that mass concentration is 5.5%, the ethyl alcohol of nanometer quality of sericite 0.5%, addition is added
It stirs under 2500r/min revolving speed into high-speed mixer 2 hours, is then adjusted to the pH of suspension using dilute hydrochloric acid solution
6.2,65 DEG C are heated to, after stirring 20min with 150r/min revolving speed, adds the ammonium persulfate of suspension quality 0.82%, stirring is equal
After even, then into suspension add nanometer quality of sericite 10% nano silica, with 200r/min revolving speed stirring 1 hour
Afterwards, then the butyl acrylate of nanometer quality of sericite 0.35% is added, is heated to 72 DEG C, kept the temperature 1 hour, then naturally cool to
Then room temperature is filtered by vacuum, be dried at 80 DEG C using vacuum oven, obtains a nanometer sericite composite particles.
Further, the centrifuge centrifugal drum inner-wall paint is coated, is formed after baking-curing, baking-curing temperature
It is 50-70 DEG C.
The present invention has the advantage that centrifuge centrifugal drum inner-wall paint prepared by the present invention has compared with prior art
Overlength durability, after weatherability, by 5000 hours artificial acceleration anti-aging tests, coating be still able to maintain good color and
Gloss, not dusting are not fallen off, and are 5-10 times of traditional coating, and corrosion resistance, chemical-resistant are strong, lazy with fabulous chemistry
Property, it by the very high crosslink density of coating of the present invention, can effectively stop the infiltration of acid, alkali etc., there is splendid corrosion resistance
And chemical resistance, soil resistance is good, and paint coatings surface of the present invention can be down to 2.2 × 108J, coefficient of friction is small, and spot difficulty is attached
, coating hardness is high, has good mechanical performance, is not easy to scratch, and also has good fungus resistance, can be good at adapting to
Working environment in centrifuge centrifugal drum.
