Description
Technical field
The application belongs to paint field, relates in particular to a kind of aqueous architectural coating.
Background technology
Coating, in China, tradition name is called paint.So-called coating is to be coated in protected or decorated body surface; and can form with coated article the continuous film of firm attachment; normally taking resin oil or emulsion as main; add or do not add defoamer, filler; add corresponding additive, with organic solvent or the formulated thick liquid of urea.Coating refers to the general name that is applied to body surface and can form the material of tough and tensile protective membrane, and building coating is an important class in coating, in China, generally will be used for inner wall of building, exterior wall, and ceiling, ground, the coating of toilet is called building coating.Building coating has decoration functions, defencive function and livability and improves function.The shared proportion of various functions is not quite similar because application target is different.Decoration functions is the function of beautifying the appearance value that improves it by buildings.Mainly comprise the design design of plane color, pattern and gloss aspect and the design of three-dimensional pattern design.But to match with the size and shape of the moulding of buildings itself and base material itself, just can fully play out.Defencive function refers to that protection buildings is not subject to the impact of environment and the function of destruction.The content that different types of protected body requires defencive function is also different.As indoor and outdoor application require the index difference that reaches just very large.
Building coating is mainly used in the coating products of house decoration as a class, its market development and real estate industry's development are closely related.Since " the tightest policy of real estate in history " put into effect, market of real estate development is absorbed in low ebb, and since especially entering 2012, the policy of expection is loosening before does not occur, is that firmly the portion of building clearly represents that in the short period of time, policy of regulation and control can not change on the contrary.Some buildingss to mildew-resistant, fire prevention, heat insulating, corrosion-resistant etc. have a particular requirement.It is mainly for indoor application that livability is improved function, contributes to exactly to improve the function of living environment, as sound-proofing, sound absorbing, antisweat etc.And universal along with humanity concept, and the formation of novel harmonious society, designs a kind of easy dispersion, fast drying, does not lump and the aqueous architectural coating of resistance to wiping excellence is very important.
