Description
Technical field
The present invention relates to a kind of white primer, relate in particular to the open white primer of a kind of UV spraying.
Background technology
Open paint claims again washing white, a kind of coating that appears the surperficial pore of ground (being generally timber) completely, the pore that can retain natural wood grain, ground clean mark, paint glue spread is little, sub-light, nature texture is strong, can be that wood grain color is beautiful, and texture is outstanding, mill base directly infiltrates ground pore, not fugitive color; Mill base is attached to substrate surface securely, can synchronize and expand with heat and contract with cold with ground together temperature influence, and at present, open paint is used very general in European top-grade furniture.
Open white (modelled after an antique white) furniture lacquer often adopts conventional P U, NC paint to construct, for example CN102500538A discloses a kind of open paint of solid wood composite door manufacturing technology, mainly comprise following operation steps: (1) corase grind: with 240 order sand paper, beat plates of solid wood surface wolline thorn, then with hairbrush, gently brush the openpore of solid wood composite door; (2) wipe Ge Lisi: the Ge Lisi according to demand modulation different colours, carries out wiping in door leaf surface; (3) priming paint spraying: after treating Ge Lisi complete drying, carry out priming paint spraying; (4) fine grinding: after treating that priming paint is dry, carry out fine grinding with 400 order sand paper; (5) cleaning door leaf surface dust, carries out finish paint spraying; (6) test package: after finish paint is dry, can pack through being up to the standards.Preparation technology is too complicated, and efficiency is low.
Ultraviolet-curing paint (UV paint) is by the automatic roller coat of machinery equipment, showering or spray on furniture plate surface, under the irradiation of UV-light (wavelength is 320-390nm), impel decomposition of initiator, produce free radical, cause resin reaction, instantaneous solidification film forming, its advantage comprises: color and luster is stable, and Chang Xin for a long time efficiently solves that door-plate fades and aberration problem; The pure flat effect of door-plate minute surface is better, and paint film is full without tangerine peel; UV paint is one of baking vanish door-plate comparing in the world at present environmental protection; Door-plate hardness is 2 times of other baking vanish door-plates, and scratch resistance is drawn, and acid and alkali-resistance is not yielding.Therefore, at furniture industry widespread use.For example patent CN102993908A has supplied a kind of UV white primer that can be used for electrostatic spraying, employing standard bisphenol type epoxy acrylic resin, thermoplastic acrylic resin, polyester acrylic resin, reactive thinner are as filmogen, under UV-irradiation, solidify, hardness of paint film is high, and sticking power is good.But UV paint solid content is high, as open paint, use and be easy to cause the sealing of timber pore, therefore, generally can only be used for making seal coat.
