" linked " is such component; It comprises compound, oligomer, polymer or the copolymer with crosslinking functionality; Said crosslinking functionality is positioned in each molecule of compound, oligomer, in the end or their combination of the side group of main polymer chain, main polymer chain, main polymer chain, wherein these functional groups are can (during curing schedule) crosslinked to produce the coating of cross-linked structure or latticed form with the crosslinkable functionality on the crosslinkable component.Those of ordinary skill in the art will recognize that the present invention does not comprise some crosslinked group/crosslinkable groups combination, because they can not crosslinked and generation film forming cross-linked structure or network.
Typical linked can be selected from compound, oligomer, polymer or the copolymer with crosslinking functionality, and said crosslinking functionality is selected from isocyanates, amine, ketimide, melamine, epoxides, polyacid, acid anhydrides and their combination.Those of ordinary skill in the art can clearly realize that some crosslinked group in the linked and some crosslinkable groups in the crosslinkable component are carried out crosslinked in general.During these make up in pairs some can comprise: (1) general and crosslinked keto-imino crosslink group of acetoacetyl, epoxy radicals or acid anhydrides crosslinkable groups; (2) general and crosslinked isocyanates and the melamine crosslinked group of hydroxyl, primary amine and secondary amine, ketimide or aldimine crosslinkable groups; (3) the general and crosslinked epoxy crosslinked group of carboxyl, primary amine and secondary amine, ketimide or acid anhydrides crosslinkable groups; (4) the general and crosslinked amine crosslinked group of acetoacetyl crosslinkable groups; (5) the general and crosslinked polyacid crosslinked group of epoxides crosslinkable groups; And (6) general and epoxides and crosslinked acid anhydrides crosslinked group of ketimide crosslinkable groups.
Coating composition also can comprise catalyst, initator, activator, curing agent or their combination.If coating composition is the coating composition of radiation-hardenable, for example ultraviolet solidifiable coating composition, then this coating composition also can comprise the radioactivation agent.
Catalyst can cause or impel the reaction between the reactant, the for example reaction between the crosslinking functionality of the crosslinkable functionality of the crosslinkable component of coating composition and linked.The amount of catalyst depends on the reactivity of functional group.Usually can adopt about 0.001% to about 5% scope, preferably adopt in 0.01% to 2% the scope, more preferably adopt the catalyst in 0.02% to 1% the scope, all percentages are the percentage by weight by the total weight of crosslinkable component solid.A variety of catalyst capable of using, for example tin compound includes machine tin compound, for example dibutyl tin laurate; Or tertiary amine, for example triethylenediamine.These catalyst can use separately or with carboxylic acid for example acetate be used.An instance of the catalyst of commercially available acquisition is Arkema (Bristol, the serial dibutyl tin laurate of Pennsylvania) selling with corresponding trade mark of Fascat
.
But one or more components of activator activation coating composition.For example, water can be as the activator of the coating of describing among the open WO2005/092934 of the PCT that announced on October 6th, 2005, and wherein water comes the activation hydroxyl through hydrolysis orthoformate group, because the orthoformate group can suppress hydroxyl and crosslinking functionality reaction.
Initator can cause one or more reactions.Instance can comprise light trigger and/or emulsion, and they can cause the photo polymerization or the curing of the coating composition (for example ultraviolet solidifiable coating composition) of radiation-hardenable receiving radiation for example during ultraviolet radiation.A lot of light triggers are that those skilled in the art are known and applicable to the present invention.The instance of light trigger can include but not limited to: benzophenone, styrax, benzoin methyl ether, styrax n-butyl ether, benzoin isobutyl ether, propiophenone, acetophenone, methyl benzoylformate, 1-hydroxy-cyclohexyl phenyl-ketone, 2; 2-diethoxy acetophenone, ethyl benzoylformate, diphenyl (2; 4; The 6-trimethylbenzoyl)-phosphine oxide, phosphine oxide, phenyl two (2,4, the 6-trimethylbenzoyl), luxuriant and rich with fragrance Kun and their combination.Also can use other commercial light trigger product or their combinations, for example available from Darocure

Can make radioactivation agent activation through radiation, cause then or the follow-up one or more reactions of catalysis.An instance can be the Photolatent catalysts available from Ciba Specialty Chemicals.
Curing agent can with other component reaction of coating composition, thereby coating composition is cured as coating.For example, linked for example isocyanates can be used as the curing agent of the coating that comprises the crosslinkable hydroxy component.On the other hand, crosslinkable component can be the curing agent of linked.
In conventional coating operation; The component of double-contracting coating composition is mixed to form the canned mixture with limited shelf life immediately before being about to spraying, wherein said component can comprise catalyst and determined other essential components of those skilled in the art of linked, crosslinkable component, necessity.Except limited shelf life, many catalyst can change its activity in canned mixture.For example, some catalyst can be to the water sensitive of trace in the canned mixture, because water can cause hydrolysis and thereby deactivation catalyst.
In order to prolong shelf life, a kind of existing method is before spraying, immediately catalyst to be mixed with other components of coating composition.Aforesaid U.S. Patent 7,201 has been described an instance in 289, and wherein catalyst solution is stored in the independent distributor, and before coating formulation is atomized, distributes catalyst solution and it is mixed with the liquid coating preparation.Yet, this method need be before atomizing mixed catalyst and liquid coating composition.
Another case description of existing method is in United States Patent (USP) 4,824,017, and wherein the catalyst of coating composition and resin are atomized separately and after atomizing, mix.Yet this class methods require through using independent pump come to atomize respectively two kinds of components and every kind of component all to need independent injection apparatus.This method also requires each atomizing and injection are thoroughly adjusted and monitored to guarantee the constant mixing ratio of these two kinds of components.
The present invention relates to a kind of spray gun that in substrate, prepares the coating composition layer.
Spray gun of the present invention can comprise: gun body (1); First inlet (10); Spray nozzle (13), said spray nozzle has the nozzle-axis longitudinally to said spray nozzle; Air nozzle (24); Second inlet (8); Second access path (11); And delivery outlet (14), said delivery outlet has the delivery outlet axis that is basically parallel to said nozzle-axis; Wherein:
