Description
Technical field
The present invention relates to a kind of Nitrocellulose, relate in particular to a kind of high gloss Nitroaldehyde ketone polyester paint for electrostatic spraying.
Background technology
Nitrocellulose is traditional coating since its drying varniss rapidly, good decorative property, easy handling, so at home and abroad be widely used.
Nitrocellulose is generally divided with volatile matter two portions by solid and forms, and comprises filmogen, pigment, auxiliary agent during solid divides.The main film forming substance of Nitrocellulose is cellulose nitrate ester, is soluble in the ester organic solvent of ketone, its solution is applied to body surface after, to stay nitrocellulose cellulose ester film gloss not high, harder crisp along with solvent evaporates, sticking power is also very low.
In addition, use synthetic resins also in a large number in the Nitrocellulose, in the situation that do not increase the solid content that viscosity can improve Nitrocellulose, and ester modified to Nitrocellulose, improve gloss, sticking power and other performance of paint film.The resin that adds in the Nitrocellulose is divided into two classes basically, i.e. hardened resin and soft resin, and the former is in the majority with Gum Rosin, and this type of resin softening point is higher, is solid state under the normal temperature.But Gum Rosin is comparatively firmly crisp, and add-on too much will affect the snappiness of paint film, thereby causes the dry and cracked of paint film.Soft resin is semi-fluid condition at normal temperatures, has thermoplasticity, Synolac commonly used, and it can improve snappiness and the sticking power of paint film, and has good gloss and outside durabitity, but add-on too much can reduce hardness, drying property and the grinability of paint film.
In addition, the protection against the tide of Nitrocellulose and water tolerance are not strong, are difficult for standing the test of warm, and more than 40 ℃ and under the condition of humidity more than 98%, the perviousness of moisture is very large, very easily bubbles or turns white in temperature, and anti-packing is poor.Resin commonly used such as Gum Rosin, Synolac are because the hydrophilic radicals such as the hydroxyl that band dissociates or carboxyl are inoperative to the raising of water tolerance.Use the softening agent of the hydrophobic naturies such as chlorodiphenyl, clorafin, butyl stearate, helpful to water repelling property, but consumption is too much unsuitable, otherwise affect other performance.
Volatilization in the pyroxylin(e)finish is divided into the mixed solvents such as ester, ketone, alcohol and benzene class.
Conductivity is to affect one of main factor of electrostatic spraying, and the main parameter of wherein estimating conductivity is the specific inductivity of coating, usually controls with the resistance value that detects coating.Too high such as resistance value, then affect the effect that oils.Common coating polarity is very low, and its impedance is more than or equal to 100M Ω.The solvent composition of volatile matter has determined the polarity of this thinner and the specific inductivity of coating, thereby affects the effect of electrostatic spraying.
Therefore, the Nitrocellulose solid divides selection and the additional proportion of middle resinous type, and the choosing and ratio of volatile matter mixed solvent, will affect to a great extent effect and the scope of application of Nitrocellulose.
The present invention selects in the resinous type of Nitrocellulose, choose aldehyde ketone resin and vibrin, simultaneously by increasing solid content, but and the viscosity of the raising of exceeding paint increase glossiness, sticking power, snappiness, water tolerance and the humidity resistance of paint film.
The present invention is for making coating be suitable for electrostatic spraying, utilize the difference of solvent polarity, adopt the higher thinner of specific inductivity, utilize simultaneously the polarity of aldehyde ketone large, the characteristics that resistance value is low, make the resistance of coating at 5～50M Ω, so that Nitrocellulose reaches good conductivity, more be suitable for electrostatic spraying.
Nitroaldehyde ketone polyester paint cost provided by the invention is low, is suitable for industrial application.
Summary of the invention
Nitroaldehyde ketone polyester paint provided by the invention is a kind of Nitrocellulose, and filmogen is selected Nitrocellulose, aldehyde ketone resin, vibrin.
The aldehyde ketone resin that the present invention selects does not contain ester bond, therefore water tolerance, moisture-proof lubricant nature are good, can keep drying varniss rapid, vibrin has good snappiness, Papillary can in the situation that do not increase the solid content that viscosity improves Nitrocellulose, improve gloss, sticking power and other performance of paint film.
Simultaneously, utilize pigment and auxiliary agent, reach to each performances such as desired gloss, fullness ratio, hardness, sticking power, snappiness, humidity resistance, color, levelling properties such as auxiliary agents such as siliceous class flow agents.
The present invention is for making Nitroaldehyde ketone polyester paint be more suitable for electrostatic spraying, adopt the higher thinner of specific inductivity, utilize simultaneously the polarity of aldehyde ketone large, the characteristics that resistance value is low, make the resistance of coating at 5～50M Ω, resistance value 100M Ω much smaller than common coating makes it reach better conductivity, more is suitable for electrostatic spraying.
The thinner of Nitroaldehyde ketone polyester paint provided by the invention forms and comprises lower boiling aliphatic hydrocarbon, propylene glycol monomethyl ether, ethylene glycol monobutyl ether, methylethylketone, isopropylcarbinol, propyl carbinol, N-BUTYL ACETATE, diacetone alcohol, toluene.This thinner has excellent conductivity, is specially adapted to the toy products such as ABS, PC, ABS+PC, has greatly improved production efficiency.
Mode by embodiment further specifies the present invention, but does not therefore limit the present invention among the described scope of embodiments.
