Description
Technical field
The present invention relates to a kind of chemistry painting industry, particularly relate to a kind of ultraviolet light polymerization (UV) finish paint that is used for the spraying of notebook computer plastic casing, the invention still further relates to the preparation method of above-mentioned coating simultaneously.
Background technology
The UV coating of present homemade notebook computer casing also is in the starting stage, and there are shortcomings such as poor adhesive force, chemical resistant properties difference in the notebook computer finish paint, is difficult to reach the rigid index of brand notebook computer producer.The exploitation of the various waterborne ultraviolet curing resins of excellent performance is the focus of studying both at home and abroad always, but how based on aqueous polyurethane acrylate system, poor performance.Ultraviolet light solidfication water polyurethane lacquer of the present invention is compared with traditional water-miscible paint, and crosslinking degree significantly improves, and performances such as hardness, gloss, vividness, chemicals-resistant, water tolerance, dry heat resistance and resistance to soiling all effectively improve, and therefore, have good prospect.
Summary of the invention
The object of the present invention is to provide a kind of paint film adhesion good, chemical resistant properties is good, and hardness is big, the notebook computer casing UV finish paint that gloss is high.This finish paint can have on the color bottom paint attached to notebook plastic casing surface or single-component well, plays effect attractive in appearance and protection ground and priming paint.
Another object of the present invention is to provide the preparation method of the UV finish paint of above-mentioned notebook computer casing spraying.
The objective of the invention is to realize in the following manner:
A kind of UV finish paint that is used for the notebook computer casing spraying is characterized in that this finish paint comprises following component, and the quality percentage composition of each component in finish paint is:
Said components quality percentage composition sum is 100%.
The UV finish paint of above-mentioned notebook computer casing spraying preferably comprises following component, and the quality percentage composition of each component in finish paint is:
Said components quality percentage composition sum is 100%.
Thinner of the present invention is mixed by benzene class, ketone, alcohols and esters solvent, benzene kind solvent, and ketones solvent, the ratio of alcoholic solvent, the esters solvent weight in thinner is: 5～30: 5～15: 5～15: 1～8.The benzene class is preferably alkylbenzene, and ketone is preferably C
3～6Ketone, alcohols is preferably C
3～6Fatty Alcohol(C12-C14 and C12-C18), the ester class is preferably C
4～10The ester class.
Described alkylbenzene is preferably toluene and dimethylbenzene, C
3～6Ketone be preferably acetone and butanone, C
3～6Fatty Alcohol(C12-C14 and C12-C18) be preferably Virahol and isopropylcarbinol, C
4～10The ester class be preferably vinyl acetic monomer and N-BUTYL ACETATE.
Described flow agent is preferably polyether-modified polydimethylsiloxane, in order to improve the levelling property of coat of painting, prevents the generation of shrinkage cavity, makes coating surface smooth, has also increased the glossiness of lacquer painting simultaneously.The preferred 1-hydroxyl-cyclohexyl of light trigger-phenyl ketone, this light trigger can be blended in this coating system well, reaches quick-setting purpose.
The preferred TMPTA of trifunctional group acrylate (Viscoat 295) has hyperergy and high crosslink density, and gloss height, hardness are big, and wear resistance is good.Two functional group propenoic acid esters can be selected HDDA (1,6 hexanediol diacrylate), and it is strong to have a diluting power, and weathering resistance is good, and plastic bottom material is had good sticking power.
The preparation method of the UV finish paint of above-mentioned notebook computer casing spraying comprises following steps:
With two functional group propenoic acid esters, trifunctional group acrylate and two functional polyurethane acrylate resins, four-functional group polyurethane acrylate resin, hexafunctional aliphatic urethane acrylates resin at normal temperatures and pressures, mix; Add flow agent and light trigger again, fully stirred 20～40 minutes; Add thinner at last.The finish paint that obtains is measured viscosity with NK-2 rock field flow cup (rock field 2# cup) when 25 ℃ of temperature, time range is 11.2s～11.8s.
Composite polyurethane acrylic resin is the main component of decision coating property in each component of notebook computer plastic casing UV finish paint of the present invention, and performances such as the hardness of paint film, gloss, sticking power are had very big influence.Composite polyurethane acrylic resin mainly comprises two functional polyurethane acrylate resins, four-functional group polyurethane acrylate resin, hexafunctional aliphatic urethane acrylates resin.Wherein the content of " polyurethane structural " is big in the two functional polyurethane acrylate resins, can strengthen wear resistance, and reducing simultaneously films explosion occurs when " high low-temperature test ", and very strong weathering resistance and water tolerance and good in being coated with property and levelling property are arranged.The four-functional group polyurethane acrylate resin has characteristics such as sticking power is good, levelling good, high-crosslinking-degree, high anti-chemical.The hexafunctional aliphatic urethane acrylates resin can form filming of high rigidity, high abrasion, and excellent water tolerance and levelling property are arranged, and coating curing speed is fast.Composite according to a certain percentage every physicals that can improve finish paint well of these three kinds of polyurethane acrylic resins, the while also effectively reduces the comprehensive cost of finish paint.
Finish paint of the present invention is suitable for notebook computer plastic casing top coat, coating method is: finish paint is applied on the material, material is placed 40～80 ℃ of down heating 10～15 minutes, and UV-irradiation 20～25 seconds forms the top coat layer of 10～20 micron thickness on material.
Adopting the special-purpose UV coating of notebook computer casing of the present invention to compare with conventional P U lacquer has the following advantages: the notebook computer plastic casing after the spraying, and particularly the PC/ABS case surface can reach the mirror effect of piano baking vanish, and gloss is at 95～100 degree; The levelling of paint film is good, and the fullness ratio height has extremely strong sticking power, and chemical resistant properties is good, hardness is big, produces the first-pass yield of wire spraying more than 90% in reality; This finish paint can also well above the priming paint attached to computer plastic casing surface single-component, can not produce the phenomenon of stinging the end.And because production technique is simple, cost is also cheap than the PU lacquer.
