摘要:
An organic-inorganic composite is useful as a sheeted filler having a high aspect ratio. A positively charged organic compound is intercalated into a non-swelling layered silicate that is composed of mica and has K ions between the layers, and has primary particles of 2 μm to 500 μm as an average particle size. The layered silicate is represented as the formula: (KaM0.1-b)(XcYd)(Si4-eAle)O10(OHfF2-f), wherein 0.6≦a≦1.0, 0≦b≦0.1, 1.0≦c≦3, 0≦d≦2, 2≦c+d≦3, 0≦e≦4, 0≦f≦2; M is a cation other than K which is between layers and at least one of Li, Na, Rb, Cs, NH4, Be, Mg, Ca, Sr, Ba, Mn, Fe, Ni, Cu, Zn and Al; X and Y are metals enclosed in an octahedral formed in a 2:1 typed sheet; X is at least one of Mg, Fe, Mn, Ni, Zn and Li; and Y is at least one of Al, Fe, Mn and Cr.
摘要:
The present invention is a method for producing swellable or nonswellable fluorine mica at a relatively lower temperature by heating a powdery mixture comprising 10 to 35% by weight of an alkali silicofluoride as the main component optionally together with an alkali fluoride and the balance of talc. This fluorine mica is used for pigments, etc.
摘要:
The present invention concerns synthetic mica powder containing from 75 to 99% of the stoichiometrical composition of fluorine and/or having a shape in which the end face of particle is laminated, process for producing such synthetic mica powder, as well as cosmetics having synthetic mica powder blended therewith, in which the synthetic mica powder shows no leaching of fluorine ions and/or improved hold of oils due to lamination at the surface of powder. Accordingly, in this invention, cosmetics excellent in extensibility, gloss, adherence and modability, having appearance of high chroma and of high stability and safety can be obtained.
摘要:
A process for preparing an inorganic filler comprising treating a particulate inorganic material with a natural or synthetic latex composition and dewatering and drying the resultant mixture. The surface-treated inorganic filler can be used with advantage in a polymeric resin composition.
摘要:
A class of pillared interlayered clay molecular sieves with large pore size were prepared by cross-linking the regularly interstratified mineral clay. Wherein the cross-linked rectorites possess an extraordinary thermal and hydrothermal stabilities. Said class of pillared interlayered clay molecular sieves are potential commercial catalysts for carbonium-ion type reactions, adsorbents and catalyst carriers.
