Abstract: The present invention provides a kind of inherent flame retardant rigid polyurethane foam. The production formula comprises 100 to 105 pbw of polyether polyol and reactive phosphorus-containing flame retardant, 2.5 to 3.5 pbw of amine catalyst, 0.8 to 2.5 pbw of tertiary amine catalyst, 0.8 to 2.5 pbw of foam stabilizer, 0.5 to 1.5 pbw of blowing agent, 135 to 150 pbw of isocyanates, and 0.05 to 0.1 pbw of organo-metallic catalyst, wherein the reactive phosphorus-containing flame retardant is 9,10-dihydro-9-oxa-10-phosphaphenanthrene-4-hydroxybenzyl alcohol. The active monomers containing flame retarding elements are introduced into main chain and side chain of PU for modification, which permanently improves the flame retardancy of PU without obvious effect on other performance of PU matrix.

Abstract: The present invention provides a POSS-containing in-situ composite nanogel with magnetic responsiveness and the method for preparing the same, wherein POSS-containing macromolecule capable of polymerizing and metal-coordination complexing is synthetized to complex with iron salt, Fe2+/Fe3+ salts are in-situ deposited via chemical coprecipitation, and crosslinking agent and initiator are added to induce polymerization so that POSS-containing nanogel ranges with magnetic responsiveness is obtained. The present invention is of professional design, feasible technique and simple operation, and prepared nanogel magnetic particles are well dispersed with excellent magnetic responsiveness, which possesses a good application prospect in medical diagnosis, sensor, catalyst carrier and biomaterial.

Abstract: A new approach for preparation and use of adhesive for metal and fabric bonding is proposed in this invention. Generally, 80-120 g of epoxy resin, 10-30 g of reactive diluent, 0.5-5 g siliane coupling agent, 0.5-5 g metallic oxide nanopowder and 35-60 g curing agent are applied in the formula. With the treatment of silane coupling agent and the mixture of phosphoric acid and nitric acid respectively, the active groups are introduced onto the surface of the metal and the fabric, which enhanced the adhesive strength of metal/fabric interface. Simultaneously, the brittleness, poor cracking and impact resistance of the traditional epoxy adhesive are also optimized by using the method of this invention, which is easy to operate and widely used.

Abstract: The present invention provides a fluorine-containing self-lubricating fabric coating material and method for preparing the same. The coating material consists of 30 to 70 pbw of fluorine resin, 10 to 40 pbw of a curing agent, 5 to 25 pbw of a reactive diluents, 0.5 to 5 pbw of a silane coupling agent and 0.5 to 3 pbw of a silicon surfactant. It is of high fluorine content and high stability. Besides, the coating material system with characteristics of self-lubricating and weather resistance is solvent-free, environmentally friendly, and has wide applications.

Abstract: The present invention provides a method for preparing high-strength cross-linked polymer photonic crystal film by core-shell polymer microspheres via evaporation-induced self assembly. Monodispersed core-shell polymer microspheres are fabricated by emulsifier-free emulsion polymerization, and then the microspheres emulsion is coated onto suitable substrates. Finally, polymer photonic crystal film with long-range ordered is constructed via self assembly. Self-cross-linking between the two units improves the strength of the polymer photonic crystal film, therefore the preparation of large size industrial-grade photonic crystal film is practicable which extends its application on the field of dyeing.
