The present disclosure relates to an inorganic composite, a method for producing the same, and a rubber composition for tires including the same. The inorganic composite according to the present disclosure is easy to handle, thereby improving safety of operators and productivity. Moreover, the inorganic composite makes it possible to uniformly disperse the inorganic particles in a rubber composition and to enhance the reinforcing effect. The rubber composition including the inorganic composite can be suitably used for eco-friendly tires requiring high efficiency and high fuel efficiency characteristics.

An object to be achieved by the present invention is to provide a pigment which is comfortable and smooth to the touch in a coating, spreads well on the skin, for example, when used in a cosmetic material such as a foundation or an eye shadow, and exhibits good color development and gloss. A pigment of the present invention is a coated pigment formed by coating a surface of a flaky base material made of at least one metal or metal oxide with a colorant. The surface of the flaky base material has a coarse particle area fraction of 9% or less. Further, it is preferable that the flaky base material be at least one or more selected from the group consisting of mica, aluminum, alumina, and glass.

The present invention addresses a need in the art by providing an aqueous inorganic pigment solution or dispersion that does require biocide to resist promotion of microbial growth.

The invention relates to a process for delamination of a layered silicate in an aqueous medium, wherein in a first step a layered silicate is treated with a delamination agent, and in a second step the thus treated layered silicate is contacted with an aqueous medium, whereby the delamination agent is a compound having exactly one positively charged atom, the positively charged atom being selected from the group consisting of nitrogen and phosphorous; contains n.sub.f functional groups selected from the group consisting of hydroxyl groups, ether groups, sulfonic acid ester groups and carboxylic acid ester groups, n.sub.f being a number from 3 to 10; comprises a total number of carbon atoms n.sub.c being from 4 to 12; has a ratio n.sub.c/(1+n.sub.f) from 1 to 2, wherein n.sub.c is the total number of carbon atoms of the delamination agent and n.sub.f is the total number of functional groups in the delamination agent as defined under ii.; contains n.sub.t atoms selected from the group consisting of carbon, nitrogen, phosphorous, oxygen and sulfur, n.sub.t being 9; and wherein the delamination agent is used to treat the layered silicate in an amount of at least equal to the cation exchange capacity of the layered silicate. The invention further relates to the thus produced delaminated layered silicates, their use in the production of composite and coating material and as a barrier material. Moreover, the invention relates to compositions containing the thus produced delaminated layered silicates.

A process for delamination of a layered silicate in an aqueous medium includes treating a synthetic or naturally occurring 2:1 clay mineral layered silicate with a delamination agent, and contacting the treated layered silicate with an aqueous medium. An amount of the delamination agent used to treat the layered silicate can be at least equal to the cation exchange capacity of the layered silicate. A delaminated layered silicate can be obtained from the process and provided in a dispersion, a composite, or a barrier.

This invention relates to manufacturing briquettes, pellets and shapes from recycled asphaltic limestone powder derived from waste residential roofing products. Briquettes and pellets are manufactured through a densification process at varying temperatures, creating recycled asphalt pellets, asphalt limestone pellets and bio mass and coal fines briquettes. Various shapes, including curbs and posts, are manufactured through heat and pressure in molds. Seawalls, walkways and wall panels are manufactured by blending asphaltic limestone powders with polymer resins and extruded or pultruded into shapes.

A mica particulate has: (a) a BET specific surface area no less than about 4.5 m.sup.2/g; and (b) a lamellarity index no less than about 2.5. A method for preparing the mica particulate comprises classifying a ground mica material, such as a wet ground mica material.

Color-bleed resistant pigment particles containing an anionic dye, a quaternary ammonium compound, and a silica and/or silicate material having a negative zeta potential are disclosed. Related methods of making these colored pigment particles also are provided.
