Shanghai species competition will launch two innovative chemical curing agent – curing agent, epoxy resin – plastic industry
HC WIRE: National University of Science and Technology Park in Shanghai, the Shanghai Chemical Technology Co., Ltd. species competition, introduction of 2 recently developed an innovative epoxy Curing agent . They are: tertiary amine side branch Polyester Modified curing agent, QNP1 low temperature latent epoxy curing agent. Chemical Technology Co., Ltd. Shanghai species competition epoxy curing agent is mainly engaged in R & D, production and application, and commitment to engineering polymer materials and chemical products and technology import and export business. The company is located in Shanghai University National Science Park, has long specialized in a number of epoxy curing agents and chemical engineering R & D technical staff, including professors, senior engineers, more than doctoral students. The company has a strong economic entity, to provide strong financial support; independent research and test center, complete specific material properties of precision analytical instruments and testing equipment, fully ensure the rigor of experimental study of reliability and product quality. Its self-developed cashew oil and polyamide curing agent curing agent used in the domestic first synthesis of cyclopentyl diamine and its derivatives have been successfully used in shipping, petroleum, construction, environmental protection, military materials, adhesives and other fields.
QNP1 low temperature latent epoxy curing agent, is a hyperbranched polymer with imidazole epoxy adduct formation of solid solution of two components. Hyperbranched polymers is ABx (X 2) type monomer by condensation reaction of soluble highly branched polymer, with highly branched three-dimensional structure, end with a number of functional groups, molecules are not crystalline, No winding, the hyperbranched polymers with high solubility, low viscosity, enhanced the reactivity of the nature of science. The company’s researchers used polymer-specific physical and chemical properties, which is used in the latent epoxy curing agent, condensation reaction using conventional preparation methods are flexible polyester, and its client base with tertiary amine modified by the introduction of tertiary amine groups, tertiary amine by-side flexible hyperbranched polyester. Through molecular design, the product curing agent which can improve the toughness of epoxy resin, so the low temperature curing agent not only latent, but also a kind of epoxy resin Modifier . QNP1 low temperature latent epoxy curing agent, has applied for patent, the project results by the Chinese Academy of Sciences, Shanghai Science and Technology Centre Charles new query identified as the leading integrated technology and reach international advanced level. May 2008 certificate by the Shanghai High-Tech Achievement Transformation Project number: 200 803 131.
Side branched polyester tertiary amine curing agent, is the company’s R & D of new epoxy curing agent. Terminal tertiary amine branched polyester curing agent, is in the company’s researchers synthesized a hyperbranched polyester based on the end of the introduction of tertiary amine groups modified, but are highly active epoxy curing agent, with Reaction and storage stability, and with the toughness of epoxy resin with improved functions. Terminal tertiary amine branched polyester curing agent has many advantages such as low viscosity, light color, to stimulate the taste of small, matching a small amount of initial gel time is long, and the mild reaction leveling effect, hardening time short, and cured color and brightness is good, strong adhesion, good temperature change performance advantages, apply top coat and high-grade adhesives. Another advantage of marketplace competition Shanghai area cashew phenol, which is from the natural waist in a Nutshell by advanced equipment and technology from refining process, can replace or partially replace the liquid phenolic amine for the preparation of phenol resins, and thermosetting liquid or powder form Phenolic resin , Its use is widespread. R & D of cashew phenol modified amine epoxy curing agents, phenolic and amine curing agent generally the most important difference is the substitution of phenol with cashew phenol by Mannich reaction of phenolic amine curing agent. The middle bit Cardanol molecules containing unsaturated double bonds of 15 carbon straight chain substituents, provides a good toughness, excellent water-repellent, low permeability and self-drying and so on.
