The functional modified pure acrylic emulsion adopts a reactive surfactant as an emulsifier, and a functional monomer is introduced. The product has excellent freeze-thaw stability. Only by adding a few amount of the freeze-thaw stabilizing agent, the stone-like coating has excellent ultralow-temperature stability.
Description
Technical field
The invention belongs to paint field, and in particular to stablize true mineral varnish and preparation method thereof to a kind of ultralow temperature.
Background technology
The water paint that true mineral varnish is made up of polymer emulsion, natural colour sand, auxiliary agent and water, mainly as exterior wall finishing
Decoration materials, which possesses ornamental strong, widely applicable, aqueous, environmental protective, good resistance to soiling, long service life, economical and practical and without safety
The characteristics of hidden danger, widely paid close attention in recent years and applied.
True mineral varnish film forming matter polymer emulsion belongs to colloidal dispersion system, thus true mineral varnish belongs to a kind of heating power on the whole
Learn unstable multiphase dispersion.Surely, when mineral varnish is frozen, the ice crystal that water is mutually formed in true mineral varnish system is to latex particle
Produce pressure and cause mutual collision and fusion between particle, and then affect the freeze-thaw stability of true mineral varnish.Freeze-thaw stability is poor
True mineral varnish in the production of cold district, storage, transport and application process, experience thermal exchange, easily cause true
Mineral varnish cosmetic variation, viscosity increase or even lump failure and loses using value.Therefore, to prevent this phenomenon from occurring, can be with
Freezed by preventing emulsion at low temperature, or postpone ice-crystal growth speed, or hinder ice crystal compression method to improve true mineral varnish
Ultralow temperature stability.
Chinese patent（Application number：201310123211.X）Disclose in latex paint, add antifreezing agent to reduce whole body
The freezing point of system, improves its freeze-thaw stability.Add small molecule antifreezing agent such as alcohols or ethers reduce the freezing point of emulsion, and then
Improve the freezing resistance stability of emulsion.But these material highly volatiles, form VOC, not only cause energy waste, also to atmospheric environment
Cause a large amount of pollutions.
The content of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of ultralow temperature stablizes true mineral varnish, the true mineral varnish is having

Powder is polyacrylic acid sodium salt or the one kind in ammonium polyacrylate dipersant；The defoamer for adopting is organic silicon defoamer or breast
One kind in liquid type defoamer；The antibacterial for adopting is the stable Kazon antibacterial of divalent metal salt.
A kind of ultralow temperature of the present invention stablizes true mineral varnish, FT- of the freeze-thaw stabiliser for adopting for Rhodoline companies
100 type freeze-thaw stabilisers.FT-100 does not contain APE and VOC, safety and environmental protection, and possesses excellent freeze-thaw stability because true mineral varnish is adopted
Pure-acrylic emulsion is film forming matter, therefore only needs minimal amount of FT-100, you can make true mineral varnish possess excellent ultralow temperature stability.
Meanwhile, FT-100 types freeze-thaw stabiliser can also improve the glossiness of these coating, the dispersibility of pigment and stain resistance.
The outstanding feature of the present invention：A kind of ultralow temperature of the present invention stablizes true mineral varnish, stable to possess excellent freeze-thaw
Property pure-acrylic emulsion be film forming matter, and add minimal amount of Diamond Search freeze-thaw stabiliser, thus it be stable to possess excellent ultralow temperature
Property, expand significantly the range of application of product.
