Description
Technical field
The invention belongs to environmentally friendly aluminium paint fields, and in particular to a kind of aqueous dumb light UV solidifications aluminium paint;In addition, this hair
The bright preparation method and application method for also relating to the aqueous dumb light UV solidifications aluminium paint.
Background technology
Aluminium paint is a kind of paint containing aluminium powder, because the good ductility of aluminium can form continuously aluminium in film
Film can cover pin hole, reduce permeability.Traditional aluminium paint application usually produces aluminium powder usually based on solvent based coating
The paint vehicle of paint is made of alkyd resin, solvent and aluminum paste, and alkyd resin is with raw materials such as polyacid, unit acid and polyalcohols
Esterification generation is carried out in resin reaction kettle.
Dumb light paint is called " sub-gloss varnish ", is one kind of paint, refers to the paint that gloss decreases compared with polish lacquer.Usually
It is divided into half sub-gloss varnish（Gloss is 40 ~ 60 or so）With full Asia（Gloss is less than 30）Two major classes, subdivision can be divided into three points to eight points Asias
The sub- degree that the not paint of equal various Asia degree, i.e. gloss do not wait between 30 ~ 80.Sub-gloss varnish is added suitable based on varnish
Made of delustering agent and auxiliary material blending, since the dosage of delustering agent is different, gloss of film degree is also different.
Coating material solidified ultraviolet light (UV) is the liquid oligomer and list caused using ultraviolet initiator in coating system
Free radical polymerization occurs for body to realize that crosslinking curing forms a kind of coating of film, because less or have without using solvent
There are green, environmental protection；Moreover, because using ultraviolet light as energy source is caused, without additional heating, therefore in coating
Energy expenditure can be reduced in solidification process and obtains faster curing rate；Because of these features, UV is coating material solidified in each row
Extensive use is just gradually obtained in industry, especially in consumer electronics product such as laptop, mobile phone industry just gradually
The polyurethane coating of high energy consumption, high VOC emission is replaced to be applied as the principal item of external coating.
Aqueous polyurethane acrylate coating has wear-resisting, corrosion-resistant and bright, soft flexible, water resistance and machinery
The characteristics such as mechanical property is good, and weatherability is good, therefore it is known as " third generation aqueous polyurethane ", become a hair of current coating
Exhibition trend.
