Abstract

The invention discloses a method for preparing a polymer composite material with fluorescent property. The method comprises the following steps of: treating a precipitate obtained by reacting zinc nitrate solution and ammonium carbonate solution in a high pressure reactor under the hydrothermal condition at the temperature of 200 DEG C for 20 to 24 hours to prepare basic zinc carbonate; and blending hydrogenated carboxylated nitrile-butadiene rubber with the basic zinc carbonate by using a twin-roll mill, and performing hot pressing and vulcanizing to prepare the polymer composite material with the fluorescent property. The preparation process does not need any organic solvent, and the prepared polymer composite material with the fluorescent property has an ultraviolet light emission peak at 353 nm of a fluorescence emission spectrum.

Description

technical field [0001] The invention relates to a preparation method of a functional polymer composite material, in particular to a preparation method of a polymer composite material with fluorescent properties. Background technique [0002] Carboxyl rubber contains a small amount of carboxyl functional groups, which can react with metal compounds to generate ionic crosslinks to form carboxylate ionomers. A small amount of metal carboxylate has an important impact on the physical properties of the polymer base, such as producing high tensile strength , Self-reinforcement, excellent friction resistance, high temperature plasticity, etc., make the obtained composite material have important commercial application value. [0003] European Polymer Journal 2007 43 pages 753-761 reported a composite material based on carboxylated nitrile rubber and magnesium oxide cross-linked by ionic bonds, the composite material has good mechanical properties; Macromolecular Materials and Engine...
