Description
Technical field
The present invention relates to ultraviolet-curing paint, be specifically related to a kind of coating with imitative porcelain effect for glass baseplate.
Background technology
Ultraviolet light polymerization utilize the energy of UV-light cause low molecule performed polymer in coating or oligomer and as reactive thinner monomer molecule between polymerization and crosslinking reaction, obtaining the paint film that hardens, is in fact realize chemical seasoning by forming chemical bond.
UV-curing technology is divided into radically curing mechanism, cationic cure mechanism, and free radical-cationic hybrid curing mechanism.
The curing speed of ultraviolet light polymerization is fast, film quality is high, low in the pollution of the environment, energy expenditure is low, therefore, more and more extensive in all departments' application of national product in recent years.
Enamel paint is the one of colored paint, and enamel paint applies that rear formed paint film is hard, flat smooth, and outer appearnce is similar to enamel.
Enamel paint conventional mostly at present is self-drying paint and PU paint, and it is as follows that PU paints common formula:
Acrylic polyol resin 70-90;
1-Methoxy-2-propyl acetate 5-10;
Flow agent 0.5-3;
Defoamer 0.1-0.6;
Solvent 10-20;
Isocyanate curing agent 40-60;
Solidifying agent solvent 30-60.
The construction technology of above-mentioned PU paint is: after preparing coating according to a certain ratio, direct spraying, toasts 1-5h between 50-90 DEG C, undercarriage wrapped product.
Application publication number a kind of coating group with imitative porcelain effect that has been the disclosure of the invention of CN102585633A, comprises priming paint, middle coating intermediate and investment precoat; Wherein, investment precoat main component comprises host and solidifying agent, and host composition mainly comprises N-BUTYL ACETATE: 5-10; Dimethylbenzene: 4-10; Acrylic polyol resin: 80-85; 1-Methoxy-2-propyl acetate: 4-8; Organosilicon leveling auxiliary agent: 0.5-2; Organosilicon antifoam additives: 0.1-0.5; Curing agent component mainly comprises N-BUTYL ACETATE: 15-30; Dimethylbenzene: 15-30; Isocyanate curing agent: 40-65.
The set time of PU paint of the prior art is long, efficiency is lower, and free TDI toxicity is too large, easily carcinogenic, harmful, the storage condition of solidifying agent requires higher, therefore, need to provide a kind of curing efficiency high, store easily, and to user and the comparatively safe coating with imitative porcelain effect of constructor.
Summary of the invention
The invention provides a kind of coating with imitative porcelain effect for glass baseplate and coating method thereof, store simple and convenient, curing efficiency is high, containing the very strong material of toxicity, to user and constructor safer.
For a coating with imitative porcelain effect for glass baseplate, comprise the priming paint, floating coating and the finish paint that apply successively on the glass substrate, wherein, in described priming paint, each ingredients weight parts consists of:
In described floating coating, each ingredients weight parts consists of:
In described finish paint, each ingredients weight parts consists of:
The weight part of described priming paint, floating coating and finish paint can adopt different benchmark, namely priming paint, floating coating and finish paint carry out mixture according to respective weight part composition respectively, when applying, the coating thickness of usual priming paint is 15 ~ 30um, the coating thickness of floating coating is 8 ~ 12um, and the coating thickness of finish paint is 8 ~ 12um.
Priming paint is white paint, and being mainly used in provides sticking power and opacifying power, eliminates glass baseplate imitates porcelain effect impact on coating, floating coating is for adding chromatograph, be mainly used in the color changing paint film, finish paint, as the top layer of paint film, is the key point that paint film embodies imitative porcelain effect.
3 ~ 6 functional polyurethane acrylate in priming paint are main filmogens, provide cross-linking set, can fast setting, xanthochromia do not occur; 1 ~ 3 functional polyurethane acrylate is secondary filmogen, improves the sticking power of priming paint, can adhere on the glass substrate, increases elasticity and snappiness, improves wear resistance and chemical resistance; Adhesion promoter can improve the adhesive ability of priming paint further, enables to adhere on the glass substrate well; UV monomer, also for improving sticking power, reducing the surface tension of priming paint, being convenient to the coating of floating coating, making the shrinkability of paint film reduce simultaneously, and snappiness becomes good; Stock white titanium dioxide grinds, and provides white background opacifying power, makes last finish paint have the white effect of porcelain; Light trigger A decomposes initiation filmogen and is cross-linked under UV-irradiation; Flow agent A for improve priming paint levelling wet performance and can the performance of repetitive coatings; Solvent orange 2 A for adjusting the viscosity of priming paint, is convenient to the coating of priming paint as thinner.
6 ~ 10 functional polyurethane acrylate B in floating coating are main filmogens of floating coating, provide cross-linking set, can fast setting, have good hardness and snappiness after making paint film crosslinked; 2 ~ 4 functional polyurethane acrylate are also main filmogens, except providing cross-linking set, can also provide excellent snappiness, and with the sticking power of priming paint and finish paint, be convenient to the wettability of floating coating on priming paint simultaneously; Modified aromatic hydroxy-aromatic resin: can improve the wettability of floating coating on priming paint further, and the viscosity of floating coating is reduced; Coating distinct colors given by mill base, while possessing imitative porcelain effect, can have distinct colors effect; Photoinitiator b decomposes initiation filmogen and is cross-linked under UV-irradiation, and flow agent B is for improving the levelling wet performance of floating coating; Solvent B for adjusting the viscosity of floating coating, is convenient to the coating of floating coating as thinner.
6 ~ 10 functional polyurethane acrylate C in finish paint are filmogens main in finish paint, and for providing cross-linking set, curing speed is fast, and good solubility-resistence is good, and scratch resistance is good; Epoxy acrylate is also the main filmogen of finish paint, and except providing cross-linking set, because its reactivity is high, can accelerate film forming speed, the hardness of paint film of formation is high, and chemical stability is good; High functional UV monomer cure speed of response is fast, and wear resistance is good, and cross-linking density is high, and improve adhesion strength and the water resistance of paint film, thermoplastic acrylic resin can reduce the contraction of finish paint simultaneously, and finish paint is attached on floating coating well; Light trigger IRGACURE184 decomposes initiation filmogen and is cross-linked film forming under UV-irradiation, and flow agent C is for improving the levelling wet performance of finish paint; Solvent C for adjusting the viscosity of finish paint, is convenient to the coating of finish paint as thinner.
Priming paint, floating coating and finish paint are ultraviolet-curing paint, not containing the material that the toxicity being similar to TDI is larger, to constructor and user comparatively safe.
Priming paint has stronger opacifying power, the imitative porcelain effect finally formed for finish paint provides porcelain white effect, floating coating is except providing the color in imitative porcelain effect (making color adjustment become easy), can also all have good adhesive ability with priming paint and finish paint simultaneously, make paint film not easily layering, improve the solidity of paint film, finish paint can fast setting, shrinkage is little, flat smooth.
6 ~ 10 functional polyurethane acrylate A and 6 ~ 10 functional polyurethane acrylate B can be the same or different, and flow agent and solvent are selected according to the difference composition of priming paint, floating coating and finish paint.
Light trigger A selects based on the filmogen of priming paint, and preferably, light trigger A is light trigger TPO or light trigger IRGACURE184.
