Abstract
The invention discloses a kind of preparation methods of high resist sagging type acrylic coating, are related to technical field of coatings, comprising the following steps: (1) aqueous acrylic emulsion synthesizes, the preparation of (2) auxiliary material, the preparation of (3) acrylic coating.The present invention makes coating using water as diluent by the preparation of aqueous acrylic emulsion, avoids the problem that using organic solvent as volatile pollution environment existing for diluent;Made acrylic coating is on the basis of mechanical property satisfies the use demand while having excellent resist sagging performance, it can effectively avoid Conventional acrylic coating after spray coating since gravity generates flowing accumulation downwards to the appearance current mark of " shedding tears " occur, and then improve the presentation quality of paint film.
Description
Technical field:
The present invention relates to technical field of coatings, and in particular to a kind of preparation method of high resist sagging type acrylic coating.
Background technique:
In paint field, acrylic resin has many excellent performances, and with the development of technology, to acrylic acid
Higher requirements are also raised for the service performance of coating, especially the thixotropic property of coating.Good thixotropic property makes paint film i.e.
Make in the case where thicker, sagging phenomenon will not occur.
Sagging phenomenon is a kind of defect frequently encountered in coating application.When coating passes through spraying or the coating of other techniques
When on to the surface being disposed vertically, due to gravity, thicker coating wet film or the excessively dilute coating wet film of viscosity can be to
Lower generation flowing accumulation, and there is the appearance current mark of " shedding tears ", seriously affect the appearance of paint film.
Currently, the common method for improving paint thixotropy includes: that thixotropic agent is added in coating by (1).Thixotropic agent due to
The reasons such as performance, side effect, additive amount is limited, very limited for the change of Rheological Property of Coating, so that made coating is anti-
Sagging performance is poor.(2) rheology control agent is synthesized in the presence of matrix resin, is finally mixed to form thixotroping resin.Rheology
It is physical mixed between controlling agent and matrix resin, the dispersion in resin needs to realize by physical agitation, is unable to get
More stable uniform product, and thixotropy is still poor, causes resist sagging performance poor.
Summary of the invention:
Technical problem to be solved by the present invention lies in one kind is provided, operation is simple, the feature of environmental protection is strong and product usability
The preparation method of high resist sagging type acrylic coating that can be excellent.
The following technical solution is employed for the technical problems to be solved by the invention to realize:
A kind of preparation method of high resist sagging type acrylic coating, comprising the following steps:
(1) aqueous acrylic emulsion synthesizes: acetone being added into initiator, stirring is completely dissolved initiator, adds
Chain-transferring agent and the monomer mixed, are heated to reflux state insulation reaction, after reaction drop gained mixture under stirring
