Description

A kind of composition of 7.5RP 8.5/3.2 pigment and be applied to the sample and the preparation method of Chinese architecture colour atla

[technical field]

The present invention relates to a kind of composition, particularly be a kind of composition of 7.5RP 8.5/3.2 pigment.

The invention still further relates to said composition and be applied to the sample of Chinese architecture colour atla,

The invention still further relates to the preparation method who prepares sample for Chinese architectural color card with said composition simultaneously.

[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.

The method for expressing GB/T 18922-2008 of building color is according to the Chinese colour system GB/T 15608-1995 formulation of encoding, and Chinese architecture colour atla national standard sample GSB16-1517-2002 compilation principles is with the relevant regulations in this standard, adopts the Chinese colour system aspect system to represent color.Chinese architecture colour atla national standard sample GSB16-1517-2002 provides effective tool using for the color normalization management of building circle.

In the production process of sample for Chinese architectural color card, can relate to multinomial important steps such as aberration Δ E, raw material, prescription and technology.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.

[summary of the invention]
