Abstract
The invention relates to the field of coatings, and particularly relates to a dual-component PU/UV dual-cured anti-doodling coating. The dual-component PU/UV dual-cured anti-doodling coating comprises the following components in percentage by weight: 58%-64% of organosilicone modified hydroxy acrylic resin, 10%-12% of organosilicone light-cured resin, 1%-2% of a photoinitiator, 1%-2% of an ultraviolet stabilizer, 1%-2% of an ultraviolet absorber, 9%-11% of a curing agent, and a solvent supplemented to 100%. The dual-component PU/UV dual-cured anti-doodling coating provided by the invention can be constructed on municipal facilities, such as stop boards, lamp posts, advertising boards, fences, shelter piles, street wall spaces, doors and windows in a spraying or hairbrush brushing manner; and gloss oil can protect the brushed surface, and can keep the service life for more than ten years after being cured.
Description
Technical field
The present invention relates to paint field, be specifically related to a kind of two component PU/UV dual cure anti-doodling paint.
Background technology
Coating and drawing at random, put up everywhere, the chewing gum that abandons is the problem that municipal sector of various countries is perplexed very much, the developed country such as West Europe and the U.S., in order to remove the dirt that these hinder city look and feel, all will drop into a large amount of manpower and materials every year.In China, along with expanding economy, what people were familiar with advertisement gos deep into, and result in a large amount of small advertisements and produce, such as many bus stop boards have been sticked advertisement and scribbled a large amount of telephone numbers, and this phenomenon is very general in many cities.This phenomenon is abroad referred to as " scribble ", and it not only damages the appearance of the city, makes troubles, also can spend a large amount of money to clean to people's life.And general anti-doodling paint mainly contains aqueous anti-doodling paint, UV anti-doodling paint, common PU anti-doodling paint now.Aqueous anti-doodling paint due to antigraffiti effect bad, also continue research and development improve the stage, UV anti-doodling paint due to needs macro-energy UV rayed solidification, outdoor construction inconvenience, common PU anti-doodling paint due to weather resistance bad, work-ing life is not long.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of two component PU/UV dual cure anti-doodling paint.
Technical problem to be solved by this invention is achieved by the following technical programs:
A kind of two component PU/UV dual cure anti-doodling paint, comprises the component of following weight percent:
Organic-silicon-modified Hydroxylated acrylic resin 58 ~ 64%; Organosilicon light-cured resin 10 ~ 12%; Light trigger 1 ~ 2%; UV light stabilizing agent 1 ~ 2%; Ultraviolet absorbers 1 ~ 2%; Solidifying agent 9 ~ 11%; And by solvent makeup to 100%.
Further, by screening, find hydroxyl value lower than less than 30 time solvent resistance significantly decline, reduce protective value, hydroxyl value higher than more than 50 time, sticking power obviously declines, and hard fragility increases, easily fall paint and suffer that external force is easily destroyed, the perfection having taken into account sticking power and solvent resistance when described organic-silicon-modified Hydroxylated acrylic resin hydroxyl value is 38 ~ 42 mgKOH/g balances, silicone content screening is being found, silicone content in Hydroxylated acrylic resin content lower than 5% time, anti-antigraffiti effect is bad, and silicone content in Hydroxylated acrylic resin content higher than 15% time, anti-scribble is very good, but film adhesive declines obviously, seem that fragility is larger, preferred silicone content is 8 ~ 12%, take into account the balance of anti-scribble and sticking power, the organic-silicon-modified Hydroxylated acrylic resin good weatherability that the present invention is used, become coating is made all to have organosilyl slipping from the inside to surface, and PU anti-doodling paint weather resistance of the prior art is bad, due to after surperficial silicone layer worn away, internal layer does not just have anti-antigraffiti effect.
Further, described organosilicon light-cured resin is the organosilicon light-cured resin of B-828 five functionality of Guangzhou Boxing Chemical Industry Science Co., Ltd, when using the organosilicon light-cured resin of five functionality, find when the screening of consumption, when organosilicon light-cured resin is less than 5%, not easily surface drying when irradiating film by portable UV curing, surface binding dust, when organosilicon light-cured resin is greater than 15%, after film parches, film is firmly crisp, loss of adhesion.Preferred organosilicon light-cured resin has taken into account the balance of drying with sticking power 10 ~ 12% time, improves anti-antigraffiti effect simultaneously; Irradiate by portable UV curing after construction, the solidification at once of UV part, make paint film at once dry, reach the effect of surface drying not binding dust, obtain UV fast setting, the double effects that PU is inexpensive, avoid PU resin drying slow, the defect of easy binding dust.And add organosilicon light-cured resin, also improve the anti-scribble performance of overall film.
Further, described solidifying agent is hexamethylene diisocyanate, this items selection be the N3390 solidifying agent of Bayer A.G.
Further, described UV light stabilizing agent is hindered amine light stabilizer, this items selection be the photostabilizer 292 of Switzerland's vapour Bagong department.
Further, described ultraviolet absorbers is hydroxy phenyl benzotriazole ultraviolet absorbers, this items selection be the UV light absorber 1130 of Switzerland's vapour Bagong department.Hindered amine light stabilizer and hydroxy phenyl benzotriazole ultraviolet absorbent use jointly, can reach better synergy, and the weathering resistance of coating is significantly improved, and for the reduction of gloss, crackle, bubble, delamination and variable color have good restraining effect.
The light trigger that the present invention uses all can realize the present invention for the light trigger that the art is common, as: 1-hydroxycyclohexyl phenyl ketone.
Solvent for use is that the art common are machine solvent and all can realize the present invention, and preferably butylacetate in the present invention.
Further, according to weight percent, described anti-doodling paint also comprises functional agent 0.1 ~ 3%.
Further, described functional agent is at least one in flow agent, defoamer, siccative.
Flow agent used, defoamer, siccative are the art and commonly use material and all can realize the present invention, and as the BYK371 flow agent of Bi Ke chemistry, the BYK088 defoamer of Bi Ke chemistry, dibutyl tin laurate is as siccative.
Further, described anti-doodling paint is made up of the component of following weight percent:
Organic-silicon-modified Hydroxylated acrylic resin 58 ~ 64%; Organosilicon light-cured resin 10 ~ 12%; Light trigger 1 ~ 2%; UV light stabilizing agent 1 ~ 2%; Ultraviolet absorbers 1 ~ 2%; Flow agent 0.5 ~ 1.0%; Defoamer 0.5 ~ 1.0%; Siccative 0.2 ~ 0.4%; Solidifying agent 9 ~ 11%; And by solvent makeup to 100%.
The present invention has following beneficial effect:
Provided by the invention pair of component PU/UV dual cure anti-doodling paint, by spraying or hairbrush brushing, can construct on urban operating mechanism, as station board, and lamppost, billboard, fence, isolation pile, along the street metope, door, window.Gloss oil can be protected and be coated with swiped through surface, can keep the work-ing life of more than 10 years after solidification.
