A kind of external application building coating
Technical field
The application belongs to paint field, particularly relates to a kind of external application building coating.
Background technology
Coating, is called paint in Chinese tradition name.So-called coating is coated in protected or decorated body surface; and the continuous film of firm attachment can be formed with coated article; normally based on resin or oily or emulsion; add or do not add promotor, filler; add corresponding additive, with organic solvent or the formulated thick liquid of tetramethylolmethane.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.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.
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 universal along with humanity concept, and the formation of novel harmonious society, designs that a kind of viscosity is high, opacifying power is high, the external application building coating of water tolerance and resistance to wiping excellence is very important.
