The invention discloses an epoxy modified organic silicon resin adhesive and a preparation method thereof. The adhesive is prepared from the following components of 10-30 parts of polyurethane modified epoxy resin, 20-70 parts of epoxy modified organic silicon resin, 20-60 parts of fluorene-based epoxy resin, 10-40 parts of carboxyl-polybutadiene acrylonitrile liquid rubber, 10-60 parts of curing agent, 1-8 parts of thixotropic agent, 0.5-3 parts of compound accelerator and 2-6 parts of coupling agent. The preparation method comprises the steps of weighing each component according to the ratio, evenly mixing the polyurethane modified epoxy resin, the epoxy modified organic silicon resin, the fluorene-based epoxy resin and the carboxyl-polybutadiene acrylonitrile liquid rubber under agitation at 50-70 DEG C; adding the curing agent, the thixotropic agent and the coupling agent and heating to 70-90 DEG C; evenly agitating, and cooling to room temperature after vacuum defoaming; and adding the compound accelerator under agitation at 40-50 DEG C until evenly mixing. The modified epoxy resin adhesive is good in adhesion and simple in process, and has good adhesion on materials such as metal, glass, and plastic ceramic.

The invention discloses a preparation method of a hydroxy-functionalized carboxyl-terminated polybutadiene-acrylonitrile copolymer / carbon nanotube conducting composite film. The method comprises the following steps: carrying out in-situ coupling reaction on a hydroxy-functionalized carboxyl-terminated polybutadiene-acrylonitrile copolymer and uniform hydroxy multiwall carbon nanotubes subjected to ultrasonic dispersion to form a polyurethane compound by using hexamethylene diisocyanate, coating a film, and drying at room temperature to obtain the hydroxy-functionalized carboxyl-terminated polybutadiene-acrylonitrile copolymer / carbon nanotube conducting composite film. The method is simple to operate and easy for film formation, and has the advantages of low energy consumption, short operation time and favorable dispersibility of the carbon nanotubes; the obtained conducting composite film can implement detection on benzene and methylbenzene solvent vapor, has the advantages of short response time, high sensitivity and high selectivity, can not cause permanent damage to the conducting film, can implement the ppm-level detection on the benzene vapor, and can implement repeated use.

The invention discloses a lightweight polycarbonate composition which comprises following raw materials, by weight, 50-90 parts of polycarbonate, 10-50 parts of polybutadiene-acrylonitrile-styrene copolymer resin, 0.2-2 parts of chemical foamer with the decomposition temperature from 200 DEG C to 260 DEG C and 0.1-1.0 part of antioxidant. The invention further provides a preparation method for the lightweight polycarbonate composition. The method includes: weighing the raw materials according to the parts by weight, feeding the raw materials into a twin-screw extruder by a metering device after the raw materials are fully mixed in a medium-speed mixer, fusing for extruding, and cooling in a die for forming. The lightweight polycarbonate composition and the preparation method thereof are fewer in kinds of the raw materials and simple in production process, the polycarbonate and the polybutadiene-acrylonitrile-styrene copolymer resin are added into the chemical foamer, so that the obtained lightweight polycarbonate composition has the advantage of low density while excellent mechanical performances are maintained.

The invention provides a polyurethane resin and its preparation method and application. The raw materials for the preparation of the polyurethane resin include polyester polyol, polybutadiene diol (HTPB), polybutadiene acrylonitrile diol (HTBN), expanded The combination of chain agent and aliphatic diisocyanate; by introducing low-polarity HTPB and HTBN into the raw materials for preparation, together with polyester polyol and aliphatic isocyanate, the overall polarity of the final polyurethane resin is greatly reduced, and it is promoted. The compatibility of TPR material makes it have high bonding fastness with TPR material without adding binder in the injection molding process, which has important research significance.
