1019 results about "Polyvinyl butyral" patented technology

Polyvinyl butyral (or PVB) is a resin mostly used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde. The major application is laminated safety glass for automobile windshields. Trade names for PVB-films include KB PVB, Saflex, GlasNovations, Butacite, WINLITE, S-Lec, Trosifol and EVERLAM.

PVB (polyvinyl butyral) film for dynamically rejecting infrared rays and resisting ultraviolet rays and preparation method thereof

ActiveCN104262874AHas the effect of heat insulation and UV protectionPlay the effect of energy saving and environmental protectionPolyvinyl butyralInfrared
The invention discloses a PVB (polyvinyl butyral) film for dynamically rejecting infrared rays and resisting ultraviolet rays and a preparation method thereof. The functional PVB film comprises cesium tungsten bronze, antimony indium oxide, indium tin oxide, titanium dioxide, nano carbon spheres, zirconium carbide, PVB resin powder, a plasticizer, a trace improver and the like. The preparation method comprises the following steps: dispersing the cesium tungsten bronze composite nanoparticles with a solvent, adding the plasticizer, stirring uniformly, adding the PVB resin powder and trace improver, thoroughly mixing, and carrying out film formation on the mixture by running to obtain the heat-insulation ultraviolet-resistant PVB film. The ultraviolet rejection ratio of the PVB film is greater than 99.0%, the visible light transmittance is adjustable within the range of 60-85%, and the infrared rejection ratio is up to 80-99%; and the PVB film can be directly used for producing heat-insulation infrared / ultraviolet-resistant safety laminated glass, can be widely used in architectural curtain walls, doors / windows, zeniths, automobile windshields and the like, and is a novel energy-saving film material.

Production method of environment-friendly water-soluble gum electrochemical aluminothermic transfer printing film

The invention relates to a production method of an environment-friendly water-soluble gum electrochemical aluminothermic transfer printing film. The production method comprises the following steps: a PET film of 6 to 15 micron is adopted as a carrier film; the carrier film is sequentially provided with four coatings such as a releasing layer, a color layer, an aluminum layer and an adhesive layer; wherein the releasing layer, the color layer and the adhesive layer coat the coating materials on a PET basal membrane substrate by a smooth roll or an anilox roll in a forward coating mode or backward coating mode; the aluminum layer is spray-plated in a vacuum spray-plating mode; the invention adopts the environment-friendly material and the production technique to produce the aluminothermic transfer printing film product, and the key points are as follows: solvent based acrylic resin, ethylene-vinyl acetate resin, ketone resin and cellulosic resin hot melt adhesive are changed into cellulose acetate and products made by cellulose acetate; and vinyl cellulose, polyvinyl butyral and powdery silicon dioxide are synthesized by water and a mixed solvent in a mode of wetting and dispersing. The production method has the characteristics of having no solvent residue harmful to human body and being beneficial to environmental protection and the like.

Anti-reflection, low-radiation and easy-cleaning coated glass capable of roasting and bending and manufacture method thereof

The invention relates to an anti-reflection, low-radiation and easy-cleaning coated glass capable of roasting and bending and a manufacture method of the coated glass. The glass is an anti-reflection, low-radiation and easy-cleaning coated laminated glass capable of roasting and bending, and the anti-reflection, low-radiation and easy-cleaning coated laminated glass capable of roasting and bending is formed by sequentially overlapping anti-reflection and low-radiation coated glass with polyvinyl butyral and a glass plate B, wherein the anti-reflection and low-radiation coated glass is structured by comprising a TiO2 photocatalyst layer, an anti-reflection film layer, a glass plate A and a low-radiation film layer which are overlapped from top to bottom in sequence. Compared with the prior art, the laminated glass manufactured from the anti-reflection, low-radiation and easy-cleaning coated glass has an easy-cleaning characteristic, also has the effects of increasing the visible light transmittance by 3 to 4% and reducing the visible light reflectance from 12 to 15% to 3 to 4%, can prevent the sight from being interfered by a projection of a matter in a car on the glass during driving, and has the visible light transmittance not less than 70% and sun light transmittance not greater than 50%; and the anti-reflection, low-radiation and easy-cleaning coated glass capable of roasting and bending is particularly suitable for a front windshield of the car.
