摘要:
A mold (10) according to the present invention is a mold for molding a surface of a laminate (60) when curing the laminate (60) obtained by laminating prepreg (62). The mold (10) has a planar plate shape and elastically deforms from the planar plate shape into a shape corresponding to a shape of the laminate (60), thereby being capable of coming tight into contact with the laminate (60). Thereby, a mold which is easy to handle can be provided.

Dendrite or asteroidal titanium dioxide micro-particles having a length of 0.2 to 0.5 .mu.m, a thickness of 0.05 to 0.1 .mu.m, and a specific surface area of 20 to 130 m.sup.2 /gram, are produced by treating hydrated titanium oxide particles with an alkali, mixing instantaneously the resulting reaction product with an amount of hydrochloric acid in a ratio of 1 to 4 mols of hydrochloric acid to one mol of the titanium oxide in the reaction product to effect a reaction, then aging under heat at 85.degree. C. or higher, and then drying or, if necessary, firing after the drying, and subsequently may be coated with at least one from oxides and hydrated oxides of elements selected from aluminum, silicon, titanium, zirconium, tin and antimony to improve the dispersibility and resistance to light of the particles, or may be coated with tin oxide containing antimony or indium oxide containing tin to make the particles electroconductive. These titanium dioxide micro-particles are useful for use in electroconductive paints, electroconductive resin compositions, paints and electroconductive paints for magnetic recording media, sunscreen cosmetics, UV screening paints and UV shielding plastic compositions and the like.

Provided is a near-infrared shielding coating agent containing: (1) an inorganic near-infrared absorbing agent; (2) a tetrafunctional silicon compound represented by general formula Si(OR1)4, a hydrolysate thereof, and/or a condensation polymerization product thereof; (3) a trifunctional silicon compound represented by general formula R2Si(OR3)3, a hydrolysate thereof, and/or a condensation polymerization product thereof; (4) a silane coupling agent represented by one of the general formulas Si(X)3—Y or R4Si(X)2—Y, a hydrolysate thereof, and/or a condensation polymerization product thereof; and (5) a solvent. This coating agent allows the formation, at an ordinary temperature between 5° C. and 40° C., of a near-infrared shielding film that has a high film hardness and is not prone to cracks.
摘要:
Ultrafine iron-containing rutile type titanium dioxide particles useful for UV shielding cosmetics, pharmaceutical compositions and UV shielding paints are disclosed. They are rutile type crystalline titanium dioxide particles having an average single particle size of 0.01 to 0.1 .mu.m and containing an iron component at a concentration of 1 to 15% by weight as expressed as Fe based on the titanium dioxide in the crystalline structure. They can be produced by using a fine titania sol comprising rutile crystallites as basic particles, precipitating iron oxide or hydrated iron oxide onto the surfaces of the titania particles to effect coating, then firing and grinding.

摘要:
A glass-impregnated, fiber-reinforced ceramic comprises a ceramic matrix having open voids, inorganic fibers embedded in the ceramic matrix in a regular or irregular orientation, and a glass matrix filling up the open voids in the ceramic matrix. The glass-impregnated, fiber-reinforced ceramic is manufactured by a manufacturing method comprising the steps of forming a fiber-reinforced ceramic comprising the ceramic matrix having open voids, and inorganic fibers embedded in the ceramic matrix, impregnating the fiber-reinforced ceramic with a glass precursor solution containing a glass precursor to stop up the open voids of the ceramic matrix with the glass precursor solution, and subjecting the fiber-reinforced ceramic impregnated with the solution to a heat treatment.
