Description
Technical field
The present invention relates to a kind of coating, particularly relate to a kind of water soluble amino acrylate resin coating and preparation method thereof, belong to water soluble paint technical field.
Background technology
Coating (paint), our the most described paint is one therein.Refer to coat body surface to form thin film under certain conditions and play protection, a class I liquid I of decoration or other specific functions (insulation, antirust, mildew-resistant, heat-resisting etc.) or solid material.Because coating in early days is mostly with vegetable oil as primary raw material, therefore also referred to as paint.Vegetable oil has been instead of at synthetic resin, therefore referred to as coating.Coating non-liquid, powdery paints is the big class of coating variety one.Coating is typically based on resin or oil, and adds or be not added with face, filler, the thick liquid modulated with organic solvent or water, also occurs in that the coating new varieties such as powdery paints existed with solid forms.No matter the form (liquid or solid) of all kinds of coating coating varieties, at least should be made up of two or three basis.I.e. it is divided into main film forming substance；Film forming subsidiary material matter and auxiliary film forming matter.Coating can be coated on surface of bottom material and form the liquid or solid macromolecular material of tough and tensile continuous film (paint film).It is once called as paint, paint.It is mainly used to play decoration and protective effect to by painting surface.Some coating also has specific function, such as high temperature resistant, cold-resistant, radioprotective etc..Coating is widely used in the aspects such as building, boats and ships, vehicle, metallic article.
The coating that water soluble paint is is solvent composition dispersion media with water, referred to as water soluble paint.Water soluble paint has formed multi items, multi-functional, multipurpose, huge and rounded system.Water soluble paint is with water-soluble synthetic resin as main film forming substance, and water is diluent, adds appropriate pigment, filler and auxiliary material etc., ground a kind of coating.Water soluble paint is divided into water soluble paint, water-dispersible paint；It is divided into again electrocoating paint, latex paint water solublity from dry or low temperature baking(stoving) enamel；Classification by use can be divided into: water solublity woodenware priming paint, ornamental water soluble paint, inner-outer wall water soluble paint for building, water for industrial use soluble paint, wherein occupies main status with water soluble paint, electrocoating paint and latex paint.
Water paint makes good with powdery paints, and the especially building coating based on water paint accounts for about 38% in China's coating total amount.Owing to water paint and its chemical characteristic of oil paint have difference substantially, water paint and oil paint product property also to have the biggest difference, then the outmoded understanding of the big branch again water paint being set in paint industry, is unscientific.Water paint should be listed as two different series in liquid coating with oil (property) paint.Therefore, the author advises in basic terminology standard, not only needs suitably to revise the standard of coating term, also should have the terminology standard of paint, paint and water paint.Their definition can be: is applied to body surface and can form a class I liquid I or the general name of solid material of the solid-state film with protection, decoration or property (such as insulation, anticorrosion, mark etc.).Including oil (property) paint, water paint, powdery paints；The coating that water soluble paint is is solvent composition dispersion media with water, referred to as water soluble paint.Water soluble paint has formed multi items, multi-functional, multipurpose, huge and rounded system.Water soluble paint is with water-soluble synthetic resin as main film forming substance, and water is diluent, adds appropriate pigment, filler and auxiliary material etc., ground a kind of coating.Water soluble paint is divided into water soluble paint, water-dispersible paint；It is divided into again electrocoating paint, latex paint water solublity from dry or low temperature baking(stoving) enamel；Classification by use can be divided into: water solublity woodenware priming paint, ornamental water soluble paint, inner-outer wall water soluble paint for building, water for industrial use soluble paint, wherein occupy main status with water soluble paint, electrocoating paint and latex paint, along with social city, technicalization, the development of hommization, water soluble amino acrylate resin coating designing a kind of good corrosion resistance, fast drying, adhesive force and excellent water resistance and preparation method thereof, to meet the market demand, it is very important.
