彩涂板着色颜料的性能、特点

彩涂卷颜料一般可分为两大类:着色颜料和体质颜料,体质颜料也叫填料,它们都不能单独成膜。它是涂料的主要成分,约占70%~80%。

彩涂卷颜料是一种不溶于水,不溶于油的固体粉末,其主要作用是呈现色彩,并有保护和装饰性能,着色颜料与连接料结合同时还可增强涂膜的物理化学性能,起到保护美化被涂物的作用。

彩涂卷颜料:赋予涂层遮盖力及增强力学和物理性能,主要起着色与遮盖作用着色颜色的主要指标是着色力和遮盖力,遮盖力是能够将被涂物面遮盖住时的最少用量遮盖好坏的能力,遮盖力取决于颜料与油料折光率之差,越大越好当某种着色颜料在基料中与其他颜料混合时,能呈现出其他颜料本身色彩未影响涂料
颜色的能力称为着色力。

填料即填充颜料(又称为体质颜料),它是一种没有遮盖力和着色力的粉状物质,主要有耐化学药品,耐候、耐磨性良好,呈中性,改涂料流变性能、封闭性能、耐温性、力学性能、施工性能,并可以大幅降低涂料的成本。

Film forming materials on coatings generally include: grease, natural resin, phenolic resin, asphalt, alkyd resin, amino resin, cellulose, perchloroethylene resin, olefin resin, acrylic resin, polyester resin, epoxy resin, polyurethane resin, elemental organic compounds, rubber, other (inorganic polymer, xylene resin, etc.). The film-forming materials are generally divided into two types: the first type in the film-forming process is called non transformed film-forming materials, which are thermoplastic, softened by heat and hardened after cooling. The other type refers to the change of composition and structure in the film-forming process, that is, the film-forming material forms a film with completely different composition and structure from the original film, which is called conversion type film-forming material. This type of film-forming material can polymerize into insoluble network polymer with different composition under the action of heat, oxygen or other substances. The function of film-forming material is to combine the pigment, filler and resin, It is the basis of coating, which determines the adhesion of coating to substrate and the physical, chemical and mechanical properties of coating.
