Description

A kind of Three piece Can gloss oil of exempting from primary coat, the sticking power had and excellent machining property
Technical field
The present invention relates to technical field of coatings, especially relate to a kind of Three piece Can gloss oil of exempting from primary coat, the sticking power had and excellent machining property.
Background technology
The printing in current coatings for tin plate printing field is all generally primary coat, ink, gloss oil three layers, primary coat refers to Bai Keding or end oil, generally, and coatings for tin plate printing bottoming, main effect is exactly the sticking power had between primary coat and tinplate, and the ply adhesion also had between ink, so after Lacquer finish, the sticking power of whole film and processibility all can be relatively good.But along with the trend requirement that Sustainable development requirement and the client of economy reduce costs, the cry exempting to be coated with primary coat is also more and more higher, exempts primary coat and not only can reduce coating use cost, can also reduce by a procedure, energy efficient simultaneously.Existing Three piece Can gloss oil, if remove primary coat, is directly coated with ink back cover light, and not good, the processed tank of sticking power that will be faced with film easily abrades and the problem such as the quick-fried paint of sterilization.Therefore, new requirement is proposed to the performance of the ink and gloss oil of exempting from bottoming coating.Especially the sticking power of gloss oil and processing characteristics are had higher requirement.
Summary of the invention
In order to solve above-mentioned prior art, the invention provides a kind of solve film adhesive and processability problems exempt from primary coat Three piece Can gloss oil.

Described main resin is modified epoxy, it is main film forming substance, containing active epoxide group in the molecular chain of epoxy resin, epoxide group can be positioned at the end of molecular chain, centre or structure circlewise, they can with polytype solidifying agent generation crosslinking reaction and formed and insoluble, molten not there is the cancellated superpolymer of three-dimensional, owing to there being the existence of polar hydroxyl groups and ehter bond in epoxy molecule chain, it is made to have excellent cohesive strength to metal or other materials surface, hardness is high, snappiness is good, and chemical stability is good.
Described aminoresin is auxiliary film forming matter, aminoresin is mixed for aminoresin resin three by masked isocyanate, urea-formaldehyde resin, benzene, wherein, masked isocyanate has excellent snappiness and curing performance, thus the processibility of assisted Extraction high product and bactericidal property; Containing polar oxygen atom on Structure of UF resin, can improve the bonding force between finish paint, flexibility is better, thus the sticking power of assisted Extraction high product; Benzene is good for the compatibility of aminoresin and various resin, and the chemical resistances such as water-fast salt spray resistance are excellent, and the good transfer printing of snappiness is good, and deep drawability is good, thus the endurance of assisted Extraction high product, suppleness and processibility; Therefore, gloss oil is made to have excellent processing characteristics by masked isocyanate, urea-formaldehyde resin, benzene for the aminoresin that aminoresin three mixes.
Described solvent is aromatic solvent.
Described cerate is polytetrafluoroethylmodified modified polyethylene wax.
Described defoamer is broken the defoamer steeping polymkeric substance and polysiloxane composition.
Described flow agent is organosilyl surface auxiliary agent.
Described catalyzer is dead front type, low polarity, Long carbon chain alkylation sulfonic acid catalyst, has excellent viscosity stability and solvency power, can make lacquer film fast curing when reducing storing temperature.
Beneficial effect of the present invention is: the present invention is compared to prior art, and have excellent cohesive strength, suppleness and processed-type, can solve and exempt from primary coat film adhesive and processability problems, tank processed reaches the effect same with there being the paint film coating of primary coat; Exempt the use of coating primary coat, decrease the operation of coating primary coat, saved the energy, reduce production cost, enhance productivity.
Embodiment
Below by specific embodiment, the present invention is described in detail.
A kind of Three piece Can gloss oil of exempting from primary coat, the sticking power had and excellent machining property, comprise component and weight percent is as follows: modified epoxy 65-70%, aminoresin 14-15%, solvent 10-15%, cerate 4-6%, defoamer 0.14-0.16%, flow agent 0.14-0.16%, catalyzer 0.07-0.08%.
Described modified epoxy is main film forming substance, containing active epoxide group in the molecular chain of epoxy resin, epoxide group can be positioned at the end of molecular chain, centre or structure circlewise, they can with polytype solidifying agent generation crosslinking reaction and formed and insoluble, molten not there is the cancellated superpolymer of three-dimensional, owing to there being the existence of polar hydroxyl groups and ehter bond in epoxy molecule chain, it is made to have excellent cohesive strength to metal and other material surfaces, hardness is high, snappiness is good, and chemical stability is good.
Described aminoresin is auxiliary film forming matter, aminoresin is mixed for aminoresin resin three by masked isocyanate, urea-formaldehyde resin, benzene, wherein, masked isocyanate has excellent snappiness and curing performance, thus the processibility of assisted Extraction high product and bactericidal property; Containing polar oxygen atom on Structure of UF resin, can improve the bonding force between finish paint, flexibility is better, thus the sticking power of assisted Extraction high product; Benzene is good for the compatibility of aminoresin and various resin, and the chemical resistances such as water-fast salt spray resistance are excellent, and the good transfer printing of snappiness is good, and deep drawability is good, thus the endurance of assisted Extraction high product, suppleness and processibility; Therefore, gloss oil is made to have excellent processing characteristics by masked isocyanate, urea-formaldehyde resin, benzene for the aminoresin that aminoresin three mixes.
