Description
Technical field
The invention belongs to emulsion paint technical fields, and in particular to a kind of emulsion paint with excellent freeze-thaw stability.
Background technique
Emulsion paint is water-dispersible paint, it is using synthetic resin emulsion as base-material, and filler is added after grinding distribution
The various refined coating of auxiliary agent.Emulsion paint has many merits different from traditional metope coating, is such as easy to brush, is dry
It is dry rapidly, paint film is water-fast, scrub resistance is good etc.；Water-soluble interior wall emulsion paint is pollution-free, it is nontoxic, without fire hazard, be easy to brush,
Dry rapid, paint film is water-fast, scrub resistance is good, and color is soft.Water-soluble interior wall emulsion paint, using water as decentralized medium, nothing has
Solvent poisonous gas bring problem of environmental pollution, good permeability, caused by avoiding because of film internal and external temperature pressure difference
Film blistering disadvantage.
For emulsion paint filler from nominally seeing that people may be allowed, which to associate, does not have very big importance, value is only for skin
Shallow emulsion paint filling is used, still, in fact, filler has a very big impact the performance of latex lacquer coat, because of filler
Type is more, and performance difference is big, and most of formulation for coating material those skilled in the art can not satisfy oneself its performance and most preferably answer
With occasion, therefore a problem will occur, and be how to improve emulsion paint various aspects of performance using tailored version filler.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of emulsion paint with excellent freeze-thaw stability is provided.
The present invention is achieved by the following technical solutions:
A kind of emulsion paint with excellent freeze-thaw stability is basic ingredient with styrene-acrylic emulsion, water, with nanometer sericite with
Attapulgite is made of filler and auxiliary agent；
The styrene-acrylic emulsion, water total weight parts be 80-100, the parts by weight of the filler are 20-30, the auxiliary agent
Parts by weight are 0.4-0.6；
The nanometer sericite is handled by citric acid-modified；
The attapulgite is by calcining, radiation treatment.
Further, the auxiliary agent is coalescing agent, defoaming agent, thickener, dispersing agent, and each mass ratio is followed successively by 0.5:
0.15:0.43:0.41.
Further, the coalescing agent is polyethylene glycol.
Further, the defoaming agent is organic silicon defoamer.
Further, the thickener is polyurethane, and the dispersing agent is sulfamic acid dipersant and polyacrylate
Dispersing agent.
Further, the styrene-acrylic emulsion and water quality ratio are 16:21.
Further, the nanometer sericite and attapulgite mass ratio are 1:8-10.
It is further, described to be handled by citric acid-modified specifically:
(1) citric acid being dissolved in deionized water and forms solution, nanometer sericite is added in adjusting pH value of solution to 4.5-5.0,
With 180r/min revolving speed stirring 2 hours；
(2) it is heated to 70-78 DEG C, keeps the temperature 1.5-2 hours, then adds the alkyl sulfonic acid of nanometer quality of sericite 2.5%
Sodium is heated to 88-90 DEG C, keeps the temperature 40min, is then filtered, and washs to neutrality, drying to constant weight.
Further, the attapulgite is by calcining, radiation treatment specifically: attapulgite is crossed 450 meshes, then
It is calcined 1.2 hours at 350-400 DEG C, is subsequently cooled to 120 DEG C, keep the temperature 10min, then grind 30min, cross 1000 meshes, then
Cooled to room temperature again uses60Co radiation appliance, cobalt source activity be 3.17PBq, irradiation dose 8-10kGy, at normal temperature
Handle 20min.
The present invention has the advantage that emulsion paint hardness of paint film of the invention is good compared with prior art, strong covering power, anti-scratch
Washing property is good, long service life, will not heave obscission, stability is high, and water resistance, resistance to acid and alkali are good, and comprehensive performance is excellent
More；By the way that attapulgite, by calcining, after radiation treatment, more easily disperse, addition treated attapulgite is to cream
There is significant positive influence in terms of shellac varnish storage, application property, toning and patience, there is fabulous promotion to imitate the gloss of coating
Fruit, and since the special construction form of modified attapulgite can reduce moisture to the empty permeability of film, do in film
Weaken film eddy motion during dry, so that the film flooding phenomenon of emulsion paint is adjusted or improve, at citric acid-modified
The synergistic effect of the sericite of reason and the attapulgite by calcining radiation treatment, the freeze thawing that can greatly improve emulsion paint are steady
Qualitative, emulsion paint is by after by freezing and subsequent fusion process, the ability for being still able to maintain original state is stronger, is not in
It solidifies, return thick or excess stickiness and the drawbacks such as increase and occur.
