Emulsion used for quick-drying high-gloss high-weatherability waterborne alkyd paint, and preparation method thereof

The invention discloses an emulsion used for quick-drying high-gloss high-weatherability waterborne alkyd paint, and a preparation method thereof. The emulsion is composed of 28 to 16.5 parts of alkydresin; 5 to 15 parts of an alcohol ether solvent; 7 to 38.5 parts of an acrylate monomer initiator solution; 1.3 to 4.5 parts of a neutralizer; and 58.7 to 25.5 parts of deionized water. The preparation method comprises following steps: an alkyd resin with an appropriate acid value is prepared, alcohol ether is taken as a solvent, under the effect of an oil soluble initiator and a chain transferring agent, an anionic unsaturated monomer, a short chain unsaturated monomer, a long carbon chain acrylate monomer, and the alkyd resin are subjected to free radical copolymerization to prepare an acrylic acid modified alkyd resin; amine neutralizing is carried out, and water is adopted for dispersion so as to obtain the emulsion used for quick-drying high-gloss high-weatherability waterborne alkyd paint. The preparation method possesses following characteristics: monomer kind selection and composition range is wide; the raw materials are easily available; the process is convenient to control;popularization and applications in practical industrialized production are convenient; and the waterborne alkyd paint prepared from the emulsion possesses quick drying performance, high gloss, and high weatherability.

Silica gel contact lenses surface modification method and preparation method of colorful contact lenses

The invention provides a silica gel contact lenses surface modification method and a preparation method of colorful contact lenses. The modification method comprises the following steps: coating the surface of silica gel contact lenses with a coating of a network pattern structure with a gradient water content, wherein the water content of the coating is higher than that of the substrate of the silica gel contact lenses, the coating is colorful or colorless, the coating is made of a biopolymer, and the silica gel contact lenses are made of a silicon-containing prepolymer or a mixture of monomers with the silicon-containing prepolymer in a polymerization manner. The surface properties of the silica gel contact lenses are improved by using the coating of the network structure with the gradient water content, the wearing effect is improved, the wearing dryness of colorful contact lenses is effectively reduced, and meanwhile the wearing comfort is also improved. The appropriate coating water content ensures exchange of a water liquid with ocular humor is ensured, meanwhile the oxygen permeability of contact lenses, appropriate moisture volatilization and moistening of the surface of the coating are ensured, and proteins can be prevented from deposition on the surface of the coating.

Emulsion for fast-drying, high-gloss, high-weather resistance water-based alkyd paint and preparation method thereof

The invention discloses a fast-drying, high-gloss, high-weather resistance water-based alkyd paint emulsion and a preparation method, comprising 28-16.5 parts of alkyd resin; 5-15 parts of alcohol ether solvent; 7-38.5 parts of acrylate monomer initiator solution; 1.3-4.5 parts of blending agent; 58.7-25.5 parts of deionized water. The emulsion first prepares an alkyd resin with a suitable acid value, and then uses alcohol ether as a solvent, under the action of an oil-soluble initiator and a chain transfer agent, anionic unsaturated monomers, short-chain unsaturated monomers, The acrylic acid modified alkyd resin is prepared by free radical copolymerization reaction between acrylate monomer and alkyd resin, which is neutralized by amine and then dispersed in water to obtain a fast-drying, high-gloss, high-weather resistance water-based alkyd coating emulsion. The method has the characteristics of monomer type selection and wide variation in composition range, easy-to-obtain raw materials and easy control of the preparation process, etc., and is easy to popularize and apply in actual industry. The water-based alkyd paint prepared by using the emulsion of the present invention has the characteristics of fast drying, high gloss and high weather resistance. features.
