Glittery metallic powder coating and preparation method thereof

ActiveCN101955720AImprove flatnessIntense metallic glitter effectPowdery paintsEpoxy resin coatingsWaxDefoaming Agents

The invention provides a glittery metallic powder coating and a preparation method thereof, which can solve the problems that the metallic glittery effect is undesirable, and the coat is easy to wear away and distributed unevenly existing in the prior art. The glittery metallic powder coating comprises the following components in percentage by weight: 50 to 70 percent of transparent powder, 25 to 45 percent of dark and light covering power, 2.0 to 5.0 percent of coarse aluminum silver powder, 0.05 to 0.5 percent of fine aluminum silver powder, 0.1 to 1 percent of wax powder, 0.1 to 1 percent of defoaming agent, and 0.05 to 0.5 percent of fluidity improver. The invention also provides a method for preparing the glittery metallic powder coating. The glittery metallic powder coating of the invention has the advantages that: the leveling can be improved; the surface of the coat has a strong metallic glittery effect, and the coat is easy to wear away and uniform in color so as to give people a fashionable and beautiful feeling and show a high-grade decoration effect, therefore, the glittery metallic powder coating is very suitable for high-grade decoration field; and meanwhile, the production cost of the glittery metallic powder coating is not high.

Preparation method of color-changing fibers

InactiveCN110528116ASimple unit structureGuaranteed normal color renderingConjugated synthetic polymer artificial filamentsDye addition to spinning solutionFiberPolyolefin

The invention provides a preparation method of color-changing fibers. The preparation method comprises the steps of preparation of color-changing powder and preparation of color-changing fibers applying the powder; the color-changing powder is prepared from polyolefin, photochromic dyes, an antioxidant, an ultraviolet absorber and a sensitizer, all the materials are uniformly mixed and granulatedthrough melting, then pulverized at low temperature and sieved to obtain the color-changing powder with a desired particle size, the powder is blended with a fiber-forming polymer, the color-changingpowder is further sheared and dispersed under the shearing function of a twin screw rod and uniformly distributed in the fiber-forming polymer in the form of solid emulsion droplets to form a core layer material of the color-changing fibers, and the core layer is wrapped with a fiber-forming polymer skin layer containing a functional auxiliary agent to obtain the photochromic fibers of a skin-corestructure. The color-changing fibers prepared by means of the method are suitable for various photochromic dyes, high in applicability and operability and simple in preparation method and have a goodcolor development effect, long service life, excellent mechanical properties and broad application prospects in the field of textiles and garments.

Modified zirconium silver-carrying powder and preparation method thereof

InactiveCN1281689CImprove discoloration problemDissolution inhibitionInorganic pigment treatmentMaterials scienceCrystallization

The invention relates to a modified silver-loaded zirconium phosphate powder, which is prepared by the following method: fully mix the silver-loaded zirconium phosphate powder and a crystallization accelerator of 3 to 20 wt% of its weight, and mix it uniformly in a place where the volume content of oxygen is more than 5v%. It is obtained by firing at 800-1100°C for 1-5 hours in an oxygen atmosphere. Described crystallization accelerator is MgO or ZnO or can generate the compound of this oxide compound when roasting, and B 2 o 3 or a mixture of compounds capable of forming this oxide upon firing, B 2 o 3 The molar ratio to MgO or ZnO is 0-0.3. The modified zirconium phosphate silver-loaded powder can be stored in the air for a long time, and does not change color when mixed with resin, which fundamentally improves the problem of discoloration of the zirconium phosphate silver-loaded powder when it is used in industries such as textiles, plastics, and papermaking; and the present invention The preparation method provided has simple procedures, easy industrial production, no by-products and no pollution to the environment. At present, it has been applied in Shanghai, Hunan and other enterprises, and the product quality is excellent.

Rust remover and preparation method thereof

ActiveCN105671563AStable in natureLong term storagePhosphorous acidRust remover

The invention discloses a rust remover and a preparation method thereof. The rust remover is prepared from the following components in percentage by mass: 60 to 80 percent of organic acid, 19 to 39 percent of inorganic acid and 0.8 to 3 percent of corrosion inhibitor, wherein the organic acid is one or more than two kinds of tartaric acid, citric acid, oxalic acid and trichloroacetic acid; the inorganic acid is one or more than two kinds of sulfamic acid, phosphorous acid and ammonium acid fluoride; and the corrosion inhibitor is benzotrizaole or / and sodium dihydrogen phosphate. According to the rust remover disclosed by the invention, the use of hydrochloric acid or sulfuric acid is completely avoided; no acid mist during rust removal is generated, the corrosion to equipment in a workshop is avoided and the labor environment is improved; meanwhile, the corrosion inhibitor is weaker in acidity, the over corrosion to workpieces is avoided and the condition that the skin of an operator is severely corroded is prevented; in addition, after a certain amount of workpieces are treated, the rust removing efficiency is reduced; and by continuously adding the rust remover disclosed by the invention, the rust removing efficiency can be restored, i.e., a rust removing bath solution disclosed by the invention can be conveniently and repeatedly used.

Powder coating with effect of color changing along with angle and preparation method thereof

ActiveCN103131306AImprove mechanical propertiesImprove adhesionPowdery paintsEpoxy resin coatingsEpoxyColor changes

The invention belongs to the field of powder coating and particularly relates to power coating with an effect of color changing along with an angle. The powder coating with the effect of color changing along with the angle comprises epoxy resin, an epoxy resin particle system corresponding to a matched curing agent A and color changing pigments and a fluorocarbon resin particle system with fluorocarbon resin and a matched curing agent B. The parts by weight ratio of the epoxy resin particle system and the fluorocarbon resin particle system is 7-3:3-7. According to the powder coating, the color changing pigments are adhered in an epoxy resin layer successfully through bonding technology. In the process of curing, the color changing pigments are sunk into the coating bottom instead of floating to the surface of the coating along with the epoxy resin. A transparent fluorocarbon resin layer floating to the upper layer has the function of protecting the color changing pigments so that the color changing pigments are antioxidative. A structure of the color changing pigments is not damaged in the whole process and the color changing effect is thoroughly played.
