Abstract
The invention discloses a high-covering power water-in-water coating and a preparation method and application thereof, wherein the preparation method comprises the following steps: and mixing the protective glue solution and the continuous phase to obtain a granulation instant mixed solution, and adding the basic colored paint into the granulation instant mixed solution to obtain the water-in-water coating.
Description
Technical Field
The invention relates to the technical field of coatings, in particular to a water-in-water coating with high covering power and a preparation method thereof.
Background
The water-in-water paint is a multi-phase suspension with continuous phase formed by small drops of water-based latex paint, and the protective glue solution forms a layer of water-insoluble flexible film on the surface of the small drops of the dispersed phase paint, and the flexible film comprises active substances on the surface of the small drops, effective components of the protective glue and the like, wherein the active substances are mainly concentrated on the surface of the small drops to protect the inner surface of the glue film and form a certain compact structure with the effective components of the protective glue, and the outer surface of the protective glue film mainly forms a 'cabin' structure for the effective components of the protective glue to play a role of mainly preventing the inter-diffusion of the inner components and the outer components of the film.
The 'cabin' structure for protecting the outer surface of the adhesive film prevents the inter-diffusion of the components inside and outside the film, and simultaneously, different small droplets (namely colored dots) in the same continuous phase are separated from each other, so that large distance gaps exist among the small droplets, the coverage in a finished product is poor, multiple spraying is needed, and the sprayed and over-thick product is easy to flow.
The conventional water-in-water production method is to add basic colored paint into aqueous solution of protective glue for granulation, and then add continuous phase after the granulation is finished, in this way, the surface of the colored dot (small liquid drop) is covered by the protective glue film formed by the effective components of the protective glue, and the state of the protective glue film cannot be changed by adding the continuous phase, namely, weak adhesion between the small liquid drops cannot be ensured, namely irreversible.
In addition, when the continuous phase contains more "active" substances, the protective glue solution will react with the continuous phase, and therefore needs to be used up within a limited time, and when the "active" substances are too much, the reaction is too fast, and the application is difficult in practical application, and when the continuous phase containing less "active" substances (such as inert emulsion is used), the protective glue film cannot be changed, and the adhesion effect cannot be realized. In addition, when the amount of protective gum added to the mixed liquid immediately after granulation is too large, adhesion between the small droplets of protective gum cannot be achieved when the effective ingredients of protective gum are much larger than those of the active substance. The content of the protective adhesive in the instant mixed liquid for granulation cannot be too low, otherwise the protective adhesive film has poor strength and is easy to break.
Disclosure of Invention
Aiming at the problems of weak covering power and poor strength of a formed protective film of the existing water-in-water coating, the invention provides the water-in-water coating with high covering power, and the preparation method is changed to achieve good covering effect and good strength.
The technical scheme of the invention is as follows: a preparation method of a water-in-water coating with high covering power comprises the following steps:
and mixing the protective glue solution and the continuous phase to obtain a granulation instant mixed solution, and adding a basic colored paint into the granulation instant mixed solution to obtain the water-in-water coating.
Further limiting, the mass ratio of the protective glue solution to the continuous phase is 1: 0.8-2, wherein the mass ratio of the basic colored paint to the instant granulating mixed liquid is 1: 0.4 to 1.6.
Further defined, the base color paint comprises the following components in parts by weight: 20-80 parts of water, 8-40 parts of first emulsion, 0.5-20 parts of pigment and filler, 4-12 parts of protective glue solution and 1.2-8 parts of first auxiliary agent.
Further defined, the first emulsion is a pure acrylic emulsion, a Wanhua 8029 emulsion, or a Badful RS-2788 emulsion.
Further defined, the first auxiliary agent comprises a cellulose thickener, a dispersant, a defoamer, a film forming auxiliary agent, an antifreezing agent, a pH regulator, a preservative and an alkali swelling thickener.
Further limited, the protective glue solution comprises the following components in parts by weight: 85-95 parts of water, 4.5-12 parts of protective glue containing magnesium lithium silicate and 0.1-0.6 part of preservative.
Further defined, the continuous phase comprises the following components in parts by weight: 20-70 parts of water, 30-80 parts of second emulsion and 1.5-8 parts of second auxiliary agent.
Further defined, the second emulsion is one of a phenylpropyl emulsion, bardethian RS5314, or bardethian 936 w.
Further defined, the second auxiliary agent comprises a film forming auxiliary agent, an antifreezing agent, a defoaming agent, a pH regulator, a mildew preventive and an alkali swelling thickener.
The beneficial effects of the invention are as follows: granulation is carried out by granulating instant mixed liquid instead of pure granulation of protective glue solution, so that the content of active substances in the main components on the outer surface of the protective glue film is greatly increased, the increase of the content of the active substances greatly reduces gaps among small liquid drops, certain acting force can be formed between the active substances and the effective components of the protective glue to show certain adhesion, and the adhesion can be strengthened by reducing the effective components of the protective glue in the protective glue film and increasing the content of the active substances; the water-in-water paint prepared by the invention has good covering capacity, and the formed film has good strength and is not easy to damage.
