Abstract
The invention mainly relates to a primer, and concretely relates to a preparation method of an aqueous two-component polyacrylic polyol white primer specially used for reaction kettles. The white primer is prepared by mixing a component A with a component B according to a weight ratio of 1:0.2-0.5, the component A is composed of polyacrylic polyol, aerosil, a semi-finished white paste, BYK141, a pigment, a filler, BYK141306, a film forming assistant and deionized water, and the component B is composed of anion modified HDI polyisocyanate. The above product paint prepared through the method solves the problem of unsatisfactory emulsification and difficult mixing of the polyacrylic polyol and the anion modified HDI polyisocyanate under low shearing force and the problems of non-uniform paint film, decrease of performances a period of time later and no adhesion caused by migration of an unbounded emulsifier in a coating layer.
Description
Technical field
The invention belongs to paint field, specifically a kind of reactor special-purpose aqueous double-component polyacrylic polyols based white primer
Preparation method and product obtained by this method.
Background technology
Traditional solvent bottom paint all has hazardous solvent and the free TDI etc. such as toxicity, benzene class, and user is had wound
Evil.And polyacrylic polyols and anion-modified HDI polyisocyanates at low shear cannot perfect emulsifying, be difficult to mix
Close.The emulsifying agent not being bonded migrates in the coating and causes that paint film is uneven, hydraulic performance decline after a period of time, do not has adhesive force.
Summary of the invention
It is an object of the invention to provide a kind of film forming uniform, stable performance, adhesive force is strong, the reactor dedicated water of environmental protection
The preparation method of property double-component polyacrylic polyols based white primer.
Technical scheme is as follows:
Component B is anion-modified HDI polyisocyanates；
Semi-finished product are starched in vain and are made up of the material of following weight portion:
Dispersant is the BYK194 type dispersant of Germany Bi Ke.
Pigment is at least one in titanium dioxide, white carbon black, phthalocyanine blue.
The preparation method of aqueous two-component white priming paint, mainly includes following preparation process:
First it is the preparation processes starched in vain of semi-finished product:
(1) stirring container in be sequentially added into polyacrylic polyols, dispersant, aerosil, stirring container
Stir under the stirring condition of 600～800r/min；
(2) continuing under the stirring condition of 600～800r/min, being slowly added to percentage by weight is titanium dioxide, and spends
Ionized water cleans this stirring container, adjustment viscosity to 120KU～130KU；
(3) under the stirring condition of 600～800r/min, stir 10-20min, and be ground to fineness with grinder and be less than
15um；
Next to that the preparation process of component A:
(1) regulation stirring container rotating speed is to 600～800r/min, is sequentially added into polyol in stirring container
Alcohol, aerosil, semi-finished product are starched in vain, BYK141, stir；
(2) under the stirring condition of 600～800r/min, pigment, filler it are slowly added to；
(3) regulation stirring container rotating speed is to 1200～1500r/min, stirs 10～15min；
(4) continue, under stirring container 1200～1500r/min rotating speed, to be sequentially added into BYK141306, coalescents；
(5) stir under the stirring condition of 600～800r/min, and clean stirring container with deionized water water,
Viscosity is adjusted to 120KU～130KU；
It is finally the preparation painting product:
During use, it is that the ratio of 1 0.2～0.5 is added into water and uniformly stirred by weight with component B by component A.
It is white that the present invention also provides for a kind of reactor prepared by above method special-purpose aqueous double-component polyacrylic polyols
Priming paint
The present invention has the following advantages and beneficial effect:
1, the product that the present invention prepares is with water as solvent or the coating of disperse medium, and it has important environment protection significance,
Asepsis environment-protecting, the not hazardous solvent such as containing benezene, without free TDI.
2, the polyacrylic polyols of the product that the present invention prepares and anion-modified HDI polyisocyanates are at low-shearing force
Under can perfect emulsifying, it is easy to mixing.
3, the product that the present invention prepares ensure that emulsifying agent group is connected on polymer chain and is uniformly distributed, and makes coating have
There are long-time stability.
