Background technology
Oil painting is a kind of traditional art manifestation that originates from west, as far back as the 15th century, European paints after finding to mix with vegetables oil and pigment on linen, the accompanying pigment of picture has stronger hardness, can variable color after dry, can keep for a long time the feeling of freshness of gloss and color and luster, use oil colour opaque, high hiding power, can from deep to shallow, successively cover, make drawing produce stereoscopic sensation.Compared with the predecessor of oil painting---the Tan Peila technique of painting, the advantage of oil painting is apparent especially: draw layer and can not come off easily, it is easier that color is connected, and color is more gorgeous, the most important thing is that oil painting can be not mouldy, and sticking power is high, can preserve for a long time.As time goes on social transition, the earliest often serve religion, there is variation taking realistic as main oil painting, works start to incorporate the element of life gradually, describe the works such as landscape, personage, article and slowly emerge appearance, and oil painting has departed from single religious undertones.The principles such as the light and shade of artist by anatomical study, perspective science, picture make works allow people feel truer, more three-dimensional, more have levels.Along with the painting style and the technique of painting constantly enrich, the school of oil painting is also developed so far and forms tens kinds from early stage single Goethe's doctrine, and abstract, modern, institute etc. emerged in an endless stream, and respectively puts extraordinary splendor.
The oil painting development of China is commonly referred to be at Riamb's hole in 1581 introduces China, developed in the Qing Dynasty, after the late Qing Dynasty reform political reform, many young students come country's study western paintings such as English, method, day on an equal basis one after another as Xu Beihong, bang grain, uncle Li, they take back west advanced person's teaching method and theory, have started the climax in epoch.The Ma Li crafts of predecessor of Ma Li company also set up and have manufactured first Chinese oil colour in that period, have started the beginning that Western painting is produced at home.
Nowadays, science and technology and material have reached unprecedented height, and oil painting is also in continuous progress, and many difficult problems are constantly broken and capture, but, on current market, still there is a general problem---oil plant separates.
Therefore, need to develop a kind of novel oil painting binder.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, a kind of oil colour binder is provided, described binder can be improved and stable oil colour slurry form, reduces oil plant separation phenomenon and occurs.
For addressing the above problem, the present invention by the following technical solutions:
A kind of oil colour binder, the component that comprises following parts by weight:
Described vegetables oil is the natural compounds of lipid acid and glycerine, can be dryness or semi-drying, comprises that being not limited to oleum lini, Thistle oil and opium poppy wet goods has one or more in the triglyceride level of height degree of unsaturation lipid acid.Preferably meet the high iodine value vegetables oil of technical requirements.
Described oil plant is a kind of polymeric vegetable oil with certain viscosity, includes but not limited to stand linseed oil.
Described thixotropic agent refers to and can make slurry obtain thixotropic auxiliary agent, and thixotropy is slurry while being subject to shearing, and denseness diminishes, while stopping shearing, and the character that denseness increases again.Comprise and be not limited to the CVP as Cray Velley, one or more in the castor oil derivatives such as 620S.Castor oil derivative is by swelling long-chain, to be mutually wound thixotroping structure and a thickening power, the state of the maintenance system that this mode can be effective and stable by disperseing, activating in non-polar solvent.
Described thickening material one is for increasing the auxiliary agent of viscosity, and the effect that can play stabilising system and reduce costs, includes but not limited to calcium carbonate, barium sulfate, white carbon black, aluminium powder, preferably one or more in calcium carbonate, barium sulfate and white carbon black.
Described thickening material two, for increasing accumulation degree auxiliary agent, includes but not limited to one or more in beeswax, stearic acid and aluminium octadecanoate, preferably one or more in beeswax and stearic acid.
Originally return a kind of oil colour composition that comprises described binder be provided, comprise the component of following weight fraction:
Described oil colour binder 40~90 weight parts
Pigment toner 3~60 weight parts
Siccative 0.8~2.5 weight part.
Binder of the present invention and described oil colour composition can adopt this area ordinary method preparation, as each component is mixed and is stirred, the present invention does not have special requirement for pigment toner and siccative, and commercially available pigment toner and siccative is all applicable to the present invention at present.
Advantage of the present invention is:
1, the thixotropic agent that oil colour binder of the present invention adopts has improved the performance of oil colour binder, strengthens the stability of binder, is difficult for occurring oil plant separation phenomenon when storage.
2, oil colour binder of the present invention is easy to produce in enormous quantities.
3, adopt batch difference phenomenon of the made oil colour composition of oil colour binder of the present invention to reduce.
4, adopt the stability of the made oil colour composition of oil colour binder of the present invention to improve, be not prone to oil plant separation phenomenon.
5, adopt the viscosity of the made oil colour composition of oil colour binder of the present invention to improve, style of writing is more comfortable.
Embodiment
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete example, further set forth the present invention, but should understand these enforcements is not to limit the scope of the invention, without prejudice to the spirit and scope of the present invention in the situation that, those skilled in the art can make changes and improvements so that it is applicable to different service condition, condition and embodiments to the present invention.
Test specification:
Thickness degree, viscosity, the test of oil plant fractional dose of implementing gained binder and oil colour are as follows:
1, thickness degree: be put in Circular glass sheet central authorities with measuring the pipe 0.1mL that materialses, one of upper pressure 50g Circular glass, then use one of 200g counterweight, is pressed on center of glass, through the 10min counterweight of taking away, measures the mean diameter of its expansion with transparent ruler.
2, viscosity: use Brookfield DV-II+PRO, test according to ASTM D2196-1999 standard.
3, oil plant fractional dose: the stability that represents slurry.
Detection method: by some of filling slurry one-tenth, leave standstill 2 months in 40 ± 1 DEG C of environment, observe the number that oil plant separates after taking out.
4, other data tests of oil colour:
Gloss: represent the luminance brightness on oil film surface, numerical value is higher, gloss is better, otherwise poor.
Detection method: adopt the Shanghai Shen Pu chemical machinery WGG60 of company limited mirror image vancometer to measure the luminance brightness of oil film, test according to ASTM D1455 standard.
