Description
[technical field]
The present invention relates to composition, particularly be the composition of pigment, and with the physical color lump of this preparation of compositions.
[background technology]
A kind of color comprises form and aspect, lightness and chroma, as long as determined form and aspect, lightness and chroma, just can determine unique a kind of color.Stipulate among the Chinese colour system GB/T 15608-1995 that in the Chinese colour system theoretical model, any color can be demarcated with the tone on the color solid, lightness and chroma, and gives certain label.Scaling method is to write out tone H earlier, writes lightness V then, writes chroma C behind oblique line, represent with H V/C, and be example with color 10BG 5.5/6,10BG represents tone, 5.5 expression lightness, 6 expression chromas.
Theoretical value from theoretical model can relate to multinomial important steps such as aberration Δ E, raw material, prescription and technology to the production process of physical color lump.Wherein, Difference Control is to weigh the unalterable quota of a national colours reproducing technology ability, and the degree of approach that aberration is more little, the color theory value is reduced into the color matter sample is high more, and technical difficulty is big more, the scientific research strength that indicates this state simultaneously is strong more, and state of the art is high more.Therefore the research and development technology of physical color lump and research and development achievement in the Chinese colour system theoretical model, embodied the sci-tech innovation ability of China, all had extremely profound significance in the status in color field, the world for development that promotes whole country color science technical field and raising country in the color field.
Coating pigment obtains physical color lump in accordance with regulations, and physical color lump is widely applied to the national life every aspect, radiation with have influence on each field relevant with color.For example, coloured manufacturing, electronic imaging, colored record, multi-media storage and transmission, liquid-crystal display, the practical sample of having contained the national standard under the method for expressing of color, relevant industries comprise: modern architecture and finishing material, clothes, textile materials, dissemination of news medium and printing industry, industries such as multimedia display color.
At present, domesticly also be in the stage of accurately to control to the technical elements that reproduces physical color lump, and this is only the core of color theory using value in the theoretical value from theoretical model.
[summary of the invention]
The composition that the purpose of this invention is to provide a kind of 10GY 9/2 pigment reaches the physical color lump of realizing with this composition, the fast light sex change and the favorable reproducibility of this physical color lump coating, and glossiness is moderate, and environmental protection.
A kind of composition of 10GY 9/2 pigment consists of by weight:
995～1005 parts of CSC-B base-materials;
PG7, pigment content are 20%, 0.31～0.33 part;
PY42, pigment content are 60%, 0.09～0.11 part;
PY138, pigment content are 27%, 1.0～1.04 parts.
Above-mentioned CSC-B base-material main component is an acrylic copolymer, and content is 30～40%, and its average molecular weight range is 15～200,000, median size is 0.1～0.2 μ m, and minimum film-forming temperature is 10～22 ℃, and second-order transition temperature is 25～35 ℃, anionic, pH value are 8.5～10.0.Select TiO for use
2Content 〉=95%, oil number＜20g/100g, the reducing power Reynolds is several now 1800, and ISO 591 R2 types are as main white pigment, and content is 8～12%.The contrast ratio of this base-material is 0.78～0.82, and stormer viscosity is 90-100KU, when incident angle is 85 °, and 5～10 ° of glossiness.
A kind of physical color lump of 10GY 9/2 color, press above-mentioned raw materials and proportioning, when incident angle is 85 °, 4 °～6 ° of its glossiness, and aberration Δ E≤0.5 between the standard value, the Chromatic color that is significantly less than GB/T 15608-1995 " Chinese colour system " national Specification are the requirement of sample aberration latitude Δ E≤3.
The preparation method of the physical color lump of above-mentioned 10GY 9/2 color comprises the steps:
1. raw material blending: the proportioning by above-mentioned 10GY 9/2 color takes by weighing raw material, mixes.
2. coating: in envrionment conditions is relative humidity 50% ± 5%, in 23 ± 2 ℃ of the room temperatures, adopts mechanical coating method, and composition evenly entirely is coated on the White Board, and the coating wet-film thickness is 250 μ m.
3. dry: as to place 50 ± 2 ℃ of dry 3～4h of accurate baking oven to constant weight composition coating, take out, be cooled to room temperature, obtain physical color lump.
Advantage of the present invention: said composition weathering resistance and stability are high, and good proportion repeatability, raw materials used and technological process meet low VOC and zero VOC environmental protection requirement and standard; It is very little that this physical color lump and the standard value in " Chinese colour system " theoretical model are compared aberration, and the order of accuarcy that color realizes is very high, and manufacture craft is concise, has extremely strong practical value.
