A kind of one-component coating composition modelled after an antique
Technical field
The present invention relates to technical field of coatings, more particularly to a kind of one-component coating composition modelled after an antique.
Background technology
Coating, popular name paint are to be coated in the body surface protected or decorated, and can be formed with coated article securely attached
The continuous film adds or does not add pigment, filler typically based on resin or oil or lotion, adds corresponding additive,
The thick liquid being formulated with organic solvent or water.Coating is a kind of material, and this material can use different construction technologies
Coated in object surface, is formed and adhered to securely, with some strength, continuous solid film.The film common name film formed in this way,
Also known as paint film or coating.By the coating of coating coating on a surface of an, the surface of coated article body is made to be isolated with surrounding medium,
To the protection played the role of to coated article body and decoration.According to function difference, coating includes:Decorative paint, anticorrosive paint,
Insulating moulding coating and fireproof coating etc..And according to the difference of application, and one-component coating and dual-component coating can be divided into, single group
Divide coating, typically belong to the coating for not needing crosslinking curing, it is only necessary to which solvent volatilization can form paint film (belonging to physical reactions);It is double
Component paints, and usually belongs to the paint of crosslinking curing, and cross-linking reaction formation paint film is generated after two kinds of component mixing and (belongs to chemistry
Reaction).The difference of one-component and two-component is exactly that one-component need not add any auxiliary products, direct spraying or roller coating
Film-forming, and the addition curing agent that is then necessarily drawn to of two-component could film-forming.Thus, in practical application,
One-component coating is easy to construct since usage is simple, has larger advantage and foreground.
In recent years, as people's quality of life improves, class promotion and the pursuit of trend of back-to-ancients to culture and arts make
The unique feature that has of some articles of the remote past successfully attracts modern, thus modern product does old pseudo-classic also get over
Hair becomes a kind of fashion.The present ornameutal handiwork period is short, if storage tens, centuries are waited to wear and do not meet people really
Desired situation, so a kind of special coating modelled after an antique comes into being, it can be such that craftwork looks like to be furrowed by rain and wind, take off
Color, corrugation, weathering, erosion, color and luster differ or some ancient collections such as floating just have, and do old modelled after an antique, are returned to from the modern times long
Historical floods in so that product has apparent history breath, and the gloss naturally to fade, color are simple and unsophisticated and texture is graceful etc.
Feature all gives out the breath in long age from the inside to surface.
But do it is old processing be not really to wear, it is more existing with similar functions coating through can't stand ultraviolet light
Irradiation is easy dusting, and xanthochromia and flexibility are poor, and water resistance, the defects of acid resistance and alkali resistance are poor, seriously restricts
The actual effect of antique-imitation coating and development to more concrete application fields.
Therefore, how to obtain a kind of both there is certain weatherability, chemicals-resistant corrosive nature, and capable of reaching preferable
The coating composition modelled after an antique of feature modelled after an antique is always manufacturer's urgent problem to be solved.
Invention content
