The preparation method comprises the following steps of: under the stirring at a high speed, adding the film-forming aid, the cosolvent, the antifoaming agent, the disinfectant, and the mildew preventive in turn, stirring at the high speed and reducing the stirring speed; adding the fluorocarbon emulsion, regulating the pH value, and regulating the viscosity by using the thickening agent to obtain pulp; stirring the pulp at a low speed, adding the color sand and sheet, and mixing to obtain the waterborne fluorocarbon texture coating. The waterborne fluorocarbon texture coating applied to a coated outer wall surface has good protection functions of water resistance, weather resistance, smudge resistance, and the like, and makes the wall surface have elegant, harmonious and serious aesthetic feeling.

A radon-screening water emulsoid paint used as decorative paint for preventing radon, benzene, xylene and formaldehyde from being educed from wall and adsorbing them contains water, hydroxyethyl cellulose, disperser, defoaming agent, levelling agent, light calcium carbonate, titanium oxide, bentone, talc powder, ethanediol, film forming agent, PVDF-acrylate copolymer and vinyl acetate-acrylate copolymer emulsion, and antibacterial mildew-proof agent.

The present invention provides a liquid crystal display having light resistance due to a polymer layer provided on a photo-alignment film, having stabilized liquid crystal alignment and having excellent display quality. In this liquid crystal display, at least one of a pair of substrates has a polymer layer, a photo-alignment film and an electrode in that order from the liquid crystal layer. The photo-alignment film aligns liquid crystal molecules horizontally, and the polarized light transmission axis of a light polarizing element on the observation surface side of the liquid crystal cells extends along the alignment direction of the liquid crystal molecules at less than a threshold voltage. The material configuring the photo-alignment film contains a material which, by means of polarized light irradiated onto the photo-alignment film, aligns the liquid crystal molecules in a direction intersecting the polarization direction of said polarized light.

The invention relates to a formula of an inner rubber layer of a low-temperature resistant fuel oil rubber tube. The inner rubber layer comprises the following components in part by mass: fluororubber 70-90, epichlorohydrin copolymer 10-30, semi-reinforcing purpose furnace black 15-30, magnesium oxide 3-6, calcium hydroxide 3-6, No.3 vulcanizer 2-5, 2-imidazolidinethione 0.3-1, adipic acid bis(2-ethylhexyl) ester 2-5. The main material of the inner rubber layer of the invention is the fluororubber and the epichlorohydrin copolymer. After adding the epichlorohydrin copolymer and the adipic acid bis(2- ethylhexyl) ester (DOA), the cold resistance is greatly improved, and high rubber elasticity is still maintained in a low-temperature environment.

The invention provides a modified acrylate polyurethane water-based paint for woodware and a preparation method thereof.
