Technical field
The present invention relates to inorganic coating technical field, specifically discloses a kind of aqueous high-temperature-resistant high humidity inorganic coating and its system
Preparation Method.
Background technology
Inorganic coating, refer to inorganic silicate inner-outer wall surface and use coating, inner-outer wall coating decoration can not only be made more attractive,
And permanent chemical bond can occur with mineral surfaces.Its service life is 5-10 times of general organic coating, or even longer.
Outer wall coating can be made, and climate does not influence with Drought-wet change.
In Chinese architecture coating market now, aqueous inorganic paint occupation rate less than 5%, this with America and Europe more than 90% city
Field popularity rate difference is far-reaching.And and for example this is big for the scale of construction of Chinese architecture coating, for environmental angle, inorganic coating but also with
The incomparable inherent advantage of organic coating.
" it is economical, efficiently, energy-conservation, ecology " form the basic principle that human development follows jointly.World in recent years
In the range of have also been proposed the general principle of sustainable development, this is all by as promoting and promote the very strong driving force that inorganic coating develops.
In fact, the development of inorganic coating has been subjected to most attention, Japan and some countries of Europe also propose " coating is inorganization "
Viewpoint.These will all indicate that this inorganic coating possesses very big advantages for development and potentiality.
It is seldom currently used for the selected water-base resin under the conditions of hot and humid and emulsion kind.And quality also it is irregular not
Together；Its alternative species of auxiliary agent and color stuffing with paint is also few.Based on some of the above reason, water-based common coating
Performance still has certain gap compared with solvent based coating, and it is in drying time, hardness, richness, water resistance, heat resistance and resistance to strong
Sour highly basic etc. is nothing like the solvent based coating of same type.This is determined by water-based system own characteristic.
Common organic high temperature-resistant high humidity coating is in construction work, basic unit-brushing primer (1 time)-organic high temperature-resistant of polishing
High humidity coating (1-2 times) is, it is necessary to two or more coating.The aqueous high-temperature-resistant high humidity inorganic coating need to have concurrently priming paint and
The advantages of finish paint, direct two edge forming, so as to save cost, production efficiency is improved again.
The content of the invention
