  • Patent number: 11760064
    Abstract: Laminated steel having a low interface bubble rate, comprising: a substrate with a surface roughness of 0.15-0.25 ?m and a modified flexible polyester film thermally laminated onto the surface of the substrate. The modified flexible polyester film is obtained by copolymerization modification of ethylene terephthalate with a low-molecular-weight aliphatic polyester. A method for manufacturing the laminated steel having an extremely low interface bubble rate, comprising the steps of: (1) preheating and then heating the substrate; (2) uncoiling the modified flexible polyester film at room temperature, and then thermally laminating same onto the substrate; and (3) cooling and squeeze-drying.

  • Publication number: 20210395448
    Abstract: The present invention provides laminated iron having excellent printability and a preparation method therefor. The laminated iron is prepared by using a mode of performing thermal-compounding on a polyester thin film having a durable and high surface tension force and a steel plate, wherein the polyester thin film is prepared by copolymerizing terephthalic acid, isophthalic acid, ethylene glycol and a fourth component and then bidirectionally stretching a co-polymer; a feeding mole ratio is that terephthalic acid:isophthalic acid:ethylene glycol:a fourth component=(135-165):(148-194):(11-15):(0.01-12); the fourth component is selected from one or more of isophthalic-5-sulfonate, 1,4-cyclohexane dimethanol, neo-pentanediol and trimellitic acid; and 800-2000 ppm of SiO2 in parts by mass is added to a copolymerized polyester by using a mode of in-situ polymerization. The laminated iron has excellent printability and satisfies usage requirements of packaging containers for food, beverage and the like.

  • Publication number: 20210347545
    Abstract: A blended polyester laminating film resistant to discoloration caused by cooking, comprising polyethylene terephthalate and polybutylene terephthalate. The blended polyester laminating film comprises three layers, i.e., upper, middle, and lower layers. One surface layer contains SiO2 in a mass fraction of 1200-2000 ppm added by in-situ polymerization. The blended polyester laminating film is manufactured by a three-layer coextrusion biaxial stretching method, and the manufacturing method is 240-275° C. A film-laminated metal sheet manufactured from the blended polyester laminating film has excellent resistance to discoloration caused by cooking, and is applied to metal containers for food and beverage packaging that require high-temperature sterilization.

  • Publication number: 20190210326
    Abstract: A method for producing a film-coated metal plate, comprising the steps of: (1) pre-heating and soaking a metal plate; (2) hot coating the metal plate with a thin film; (3) cooling the metal plate; (4) compressing the metal plate to dry it; (5) reheating and post-processing the metal plate. This method is able to produce a metal plate having a thin film coated on the surface thereof and to easily control the thickness of a melting layer of the thin film in the process of production, especially control the difference between the thicknesses of the melting layers on both sides; and meanwhile, this method is able to increase the cooling rate. Accordingly, this method enhances the performance of the film-coated metal plate and increases the application range of the film-coated metal plate by means of a more environmentally friendly producing process and lower energy consumption, and is able to produce good economic and social benefits.

  • Patent number: 10190197
    Abstract: Disclosed herein are new face-centered cubic (f.c.c.) high-entropy alloys with compositions (in atomic %) of FeaNibMncAldCreCf where a is between 37-43 atomic %, b is between 8-14 atomic %, c is between 32-38 atomic %, d is 4.5-10.5 atomic %, e is between 2.5-9 atomic % and f is between 0-2 atomic %. The undoped alloy has strength of 159 MPa and 40% elongation to failure, but the doped, carbon-containing alloy having 1.1 atomic percent carbon has yield strength of 360 MPa, an ultimate tensile strength (UTS) of 1200 MPa and 50% elongation to failure at room temperature. At 700° C., the yield strength is 214 MPa with 24% elongation to failure. Thus, the present alloy may replace austenitic stainless steels in applications where better strength is needed at both room temperature and elevated temperature in an oxidation resistant alloy.
