Description
Technical field
The present invention relates to a kind of coating of UV anaerobic double curing, be specially adapted on the porous substrates such as timber, density board, paper.
Background technology
Ultraviolet-curing paint has dry rapid, hardness advantage high, with short production cycle because of it, and Application Areas is more and more broader at present.But conventional ultraviolet-curing paint also has its inherent defective promptly: have only filming that ultraviolet luminous energy shines directly into, could take place to make the completely solidified of filming, thereby obtain excellent film performance than crosslinking reaction more completely.But, for some recessed prominent injustice in surface, the dead angle is arranged or the object of male and female face is arranged, when with the filming of ultraviolet-curing paint that UV-irradiation was coated with, have that partly film can't be by UV-irradiation, the result has influenced the performance of finally filming.For this reason, in conventional ultraviolet-curing paint, add the ultraviolet-curing paint that to form dual cure with the solidifying agent of hydroxyl reaction.The main UV-irradiation that relies on of filming of this coating is solidified, and be not to utilize the solidifying agent that adds in the coating and the component of hydroxyl to be cured by filming of being mapped to of ultraviolet lighting, so just remedy the above-mentioned defective of conventional ultraviolet-curing paint, improved the performance of finally filming.But, resemble porous substrates such as timber, density board, paper, in coating ultraviolet-curing paint process, understand the particularly low molecular reactive thinner of some coating composition, penetrate in the hole of porous substrate, shine these coating compositions and UV-light can not penetrate base material, so they just can not solidify.And the ultraviolet-curing paint that adopts the dual cure add solidifying agent is when being used for porous substrate, then because the material difference of porous substrate, the coating composition and the quantity that penetrate in the porous substrate are all uncontrollable, its quantity that adds solidifying agent also just is difficult to determine, therefore can't guarantee to infiltrate the coating composition completely solidified in the porous substrate, and these do not have the particularly low molecular reactive thinner of completely crued coating composition, also can constantly discharge between the usage period afterwards, thereby become the new source of pollution that human body and environment are worked the mischief.
Summary of the invention
The objective of the invention is to, a kind of coating that is applicable to the UV anaerobic double curing of porous substrate is provided, formed appearance of film is smooth, and sticking power, snappiness, hardness, resistance to boiling water obviously improve, and does not have residual smell.
Realize the technical scheme of the object of the invention: a kind of coating of UV anaerobic double curing, contain esters of acrylic acid living oligomer, reactive thinner, light trigger, solvent, auxiliary agent, it is characterized in that, also contain anaerobic curing agent composition, each component shared per-cent in the coating gross weight is: esters of acrylic acid living oligomer 30%～60%; In the reactive thinner, with the compound 5%～30% of 1 ethylenical unsaturated double bonds, with the compound 0%～20% of 2 ethylenical unsaturated double bonds, the compound 5%～20% of 〉=3 ethylenical unsaturated double bonds of band; Solvent 0%～30%; Light trigger 1%～10%; Auxiliary agent 0～1%; Anaerobic curing agent composition 0.1%～5%.
