Description
Technical field
The present invention relates to the environmental protection semitransparent teak color calcined sienna superfine aqueous color sizing dispersion of a kind of low VOC that is used for the aqueous wooden ware paint toning (refer to steam below b.p.250 ℃ organic compound), no APE (alkylphenol).
The invention still further relates to a kind of preparation method of environmental protection semitransparent teak color calcined sienna superfine aqueous color sizing dispersion.
Background technology
Wood lacquer almost was a solvent based coating in the past, and the VOC that volatilizees in a large number does great damage to environment, and along with continuous advancement in technology, the aqueous woodware paint technology is gradually improved, and a kind of semi-transparent open-birth of the usefulness of mixing colours is received aqueous color paste and arisen at the historic moment.
When woodwork coating, particularly American application, the living powder of receiving is indispensable raw material, normally will forge the living toner of receiving and make wood grain wiping look and Lacquer finish colouring matter (Graintone Wiping Stain And Glaze Tints), is commonly referred to as Ge Lisi (Glaze) at home.The living powder of receiving is gained the name with the place of production, and living (Umber) He Shengna different varietiess such as (Sienna) of receiving is arranged, and is refining from natural mineral and product that get.Receive the semitransparent teak look of aqueous color paste series as semi-transparent open-birth and forge to give birth to and receive aqueous color paste, have good weathering resistance, ultraviolet-absorbing, translucency and high tinting strength; Has good chemical stability, good alkaline-resisting/acid resistance, good temperature tolerance; Forge to give birth to as the semitransparent teak look of mineral dye and receive aqueous color paste, also have ne-leakage, do not have migrating property and characteristics such as insoluble.
Ultraviolet ray is to destroy xyloid arch-criminal, and the semitransparent teak look forge give birth to receive aqueous color paste can the strong absorption ultraviolet radiation, thereby protect wooden; Can make the wooden good coloring effect that plays, color is soft, can make wooden maintenance native texture again.The semitransparent teak look is forged the living aqueous color paste of receiving and is mixed with organic transparent pigment and dyestuff when using, can not only enrich the color of pigment, improve chroma, and problem such as the weathering resistance that exists can improve organic transparent pigment of independent use and dyestuff significantly time the, temperature tolerance difference, thereby the semitransparent teak look is forged the living aqueous color paste of receiving and is had broad application prospects at aspects such as wooden furniture paint tonings.
Because translucent forging gives birth to that to receive powder careful little, specific surface area is big, higher oil number; Produce powerful interface strength between particle, the ratio of particle tightly bonding very difficult dispersion, particularly water-based system pigment is great, and the tendency of sinking in the water-based deadweight is big; And to the environmental requirement height of pigment dispersions, low VOC volatilization, thereby, forge at preparation semitransparent teak look and to give birth to when receiving aqueous color paste, very crucial to the selection of auxiliary agents such as wetting dispersing agent, dispersing apparatus and technology.
Summary of the invention
The objective of the invention is in order to overcome technical problem recited above, a kind of both had good tinting strength and translucency are provided, has good chemical stability again, advantages such as good alkaline-resisting/acid resistance, photostabilization, weathering resistance, ultraviolet attractability, thermotolerance, resistance to migration, and the semitransparent teak color calcined sienna superfine aqueous color sizing dispersion of the environment-friendly type that preparation cost is low, the present invention also provides the preparation method of this semitransparent teak color calcined sienna superfine aqueous color sizing dispersion simultaneously.
