A kind of polyvinyl alcohol aqueous architectural coating
Technical field
The application belongs to paint field, relates in particular to a kind of polyvinyl alcohol aqueous architectural coating.
Background technology
Coating, is to be applied to body surface can form and have protection, decoration or property one class I liquid I of solid-state film of (as insulation, anticorrosion, mark etc.) or the general name of solid material, comprises oil (property) paint, water-miscible paint, powder coating.Paint is flowable liquid coating, comprises oil (property) paint and water-miscible paint.China's coating circle more authoritative " coating process " book is definition like this: " coating is a kind of material, and this material can be coated in article surface by different construction technologies, forms and adheres to firmly, has some strength, continuous solid film.The film common name film forming like this, claims again paint film or coating." paint finishing can and form the material of complete and tough and tensile protective membrane with the fine bonding of body material in body surface, is called coating.Coating and paint are identical concepts.Paint is people's custom titles used for a long time, introduces after China, just utilizes in building trade always.The effect of coating may be summarized to be three aspects: provide protection, decoration function, specific function effect.The general composition of coating: comprise filmogen, color stuffing, solvent, auxiliary agent.
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.Paint is taking organic solvent as medium or high solid, solvent-free oil-base paint.Water-miscible paint is used water dissolving or the coating with water-dispersion.
Coating is as one of main material of house decoration, and the large percentage accounting in decorations is bought the whether qualified environment that directly has influence on entirety finishing effect and room of coating, sometimes even can produce harm greatly to the health of human body.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, the polyvinyl alcohol aqueous architectural coating that designs a kind of good stability, fast drying, alkali resistance and resistance to wiping excellence is very important.
