  • Patent number: 10287437
    Abstract: The present invention relates to a method for preparing pearlescent pigment through metal oxide coating based on a sheet-like substrate, and the obtained pearlescent pigment. The present invention further relates to a method for preparing pearlescent pigment through coating a sheet-like substrate by hydrolyzing metal salt under an acid condition, wherein a pH value is adjusted by using inorganics such as MgO, MgOH or CaCO3 that does not dissolve in water but can dissolve through reacting with an acid. According to the method, no free metal oxide is generated when the metal salt is hydrolyzed, so that the production cost is reduced, product quality is improved, problems possibly generated in an application process of the product are avoided, and a production process is more environment-friendly.

  • Publication number: 20140102332
    Abstract: Disclosed are a functional reinforcing filler including inorganic particles surface-modified with an alkenylsilanol obtained by hydrolyzing an alkenylalkoxysilane compound, and a method for preparing the same. Since the disclosed functional reinforcing filler has a functional group having a double bond, it has good reactivity for styrene-butadiene rubber and sulfur. Thus, when used as a functional reinforcing filler in the manufacture of rubber, it allows improvement of physical properties through adjustment of the addition amount of sulfur without additional use of the coupling agent. In addition, because of superior hydrolysis reactivity, the problem of alcohol can be solved and a rubber mixture with long scorch time can be prepared. In particular, when the functional reinforcing filler of the present invention is used in the manufacture of tires, improvement in modulus, tensile strength, rotational resistance and wet traction performance can be expected.
