Description
Technical field:
The invention belongs to color spray print media fields more particularly to a kind of aluminium system waterproof glossy canvas and preparation method thereof.
Technical background:
Canvas refers to that the infiltrations such as ink, solvent and water can be prevented by being coated with one or more layers on certain specific dry goods substrates
Back cover coating primer, for Freehandhand-drawing or as the dry goods of color spray print media.Using after numerial code spray drawing be used for advertisement and interior
The canvas of decoration is known as color spray inkjet printing canvas.With the development in world information epoch, inkjet printing technology is gradually big
Type, output are rapid, and color spray inkjet printing canvas has been largely used to Freehandhand-drawing picture, decoration painting, mountain ink and wash, oil painting product
It is imitated etc..Especially mountain ink and wash and oil painting product are copied, compared with the traditional oil painting art work, color spray ink-jet is beaten
The advantages of stamp-pad ink painting canvas is cheap, facilitates maintenance promotes market to the demand and development of the art work, domestic cultural product, right
The demand of color spray inkjet printing canvas obviously increases, for the printing effect and appearance glossiness of ink-jet canvas print media
Requirement it is also higher and higher.
Swelling type and pore type can be divided into suitable for the canvas of inkjet printing currently on the market.Swelling type ink-jet printing ink
Painting canvas, appearance glossiness is higher, mainly carries out blotting by the swelling principle of polyvinyl alcohol, is swollen speed by polyvinyl alcohol itself
It is slower that rate influences blotting speed.And polyvinyl alcohol meet the instant characteristic of water cause such bloom canvas product waterproof property compared with
Difference, in the case where current aqueous printer is widely applied, product limitation is obvious.And pore type inkjet printing canvas is main
It is to have rate of drying fast, the good feature of waterproof performance by coated filler gap blotting；Pore type inkjet printing canvas is again
Aluminium system and two kinds of silicon systems can be divided into, wherein silicon systems pore type inkjet printing canvas, matt appearance, need to add work in the later period
Sequence improves appearance glossiness, in the use of most of consumer brings inconvenience.And aluminium system pore type ink-jet printing ink
Painting canvas, appearance glossiness is high, does not need to add process in the later period to achieve the effect that bloom, waterproof, cost is relatively low, production process
Simply.But since oil painting cloth base material woven design sense itself is strongly clear, it is uneven between textile yarn and aluminium system waterproof glossy
The easy cracking behavior of coating itself causes aluminium system waterproof glossy coating to be coated with application on canvas, produces a kind of aluminium system waterproof
When bloom canvas, it is easy to appear ink-absorbed coated layer fracture, prints the problems such as air brushing effect is uneven.
