A kind of polyvinyl alcohol aqueous architectural coating
Technical field
The application belongs to paint field, particularly relates to a kind of polyvinyl alcohol aqueous architectural coating.
Background technology
Coating, is be applied to body surface can be formed and have protection, the class I liquid I of solid-state film of decoration or property (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 adhere well, has some strength, continuous print solid film.The film common name film of such formation, also known as paint film or coating." paint finishing can bond very well with body material in body surface and form the material of complete and tough and tensile protective membrane, is called coating.Coating and paint are identical concepts.Paint is people's custom titles used for a long time, after introducing 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 and is applied to body surface and the general name forming 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, ceiling, ground, and the coating of toilet is called building coating.Building coating has decoration functions, defencive function and livability and improves function.Proportion shared by various function is not quite similar because application target is different.Decoration functions is the function of beautifying the appearance value improving it by buildings.Mainly comprise the design design of plane color, pattern and gloss aspect and the design design of three-dimensional pattern.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 architecture protection thing not by the impact of environment and the function of destruction.The content that different types of protected body requires defencive function is also different.As just very large in the indoor index difference with reaching required by outdoor application.Paint take 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 the main material of house decoration, and the large percentage accounted in decorations, buys the whether qualified environment directly having influence on overall 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, and its market development and real estate industry develop closely related.Since " in history the tightest policy of real estate " is put into effect, market of real estate development is absorbed in low ebb, and since especially entering 2012, the policy of before expecting loosens and do 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 particular requirement.Livability improves function mainly for indoor application, contributes to the function improving living environment exactly, as sound-proofing, sound absorbing, antisweat etc.And popularizing along with humanity concept, and the formation of novel harmonious society, the polyvinyl alcohol aqueous architectural coating designing a kind of good stability, fast drying, alkali resistance and resistance to wiping excellence is very important.
