Embodiment Construction
[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0017] A thermoplastic polyurethane matrix resin. The raw material components include: diisocyanate, small molecular diol, macromolecular diol, chain extender, solvent, nano oxide material and epoxy resin. Firstly, diisocyanate, small molecular diol Put the polyalcohols and macromolecular diols into the reaction vessel, carry out vacuum dehydration, and then raise the temperature to 130°C for heat treatment; disperse the nano-oxide material in the high-speed dispersion equipment for 45 minutes to obtain a dispersion liquid, and add it to the reaction vessel , raise the temperature to 84°C for 1 hou...

The invention discloses a thermoplastic polyurethane matrix resin. The thermoplastic polyurethane matrix resin comprises diisocyanate, small molecular diol, macromolecular diol, a chain extender, a solvent, a nano-oxide material and an epoxy resin. The nano-oxide material is introduced into a polyurethane macromolecular chain through a chemical method, and the integration effect of high specific surface area, high activity and molecular weight of the nanoparticles is utilized to make hydrogen bonds concentrated in order to form an ordered crystal structure, so the tear resistance of the polyurethane resin is remarkably improved; and the modified epoxy resin is added to increase the tensile property and the wear resistance, so the polyurethane resin has excellent mechanical wear resistance.
Description
technical field [0001] The invention relates to the field of polyurethane matrix resin preparation, in particular to a thermoplastic polyurethane matrix resin. Background technique [0002] Polyurethane matrix resin is a new type of synthetic material. Due to its special molecular structure, it combines the high elasticity of rubber and the high strength of plastic. Therefore, it has developed rapidly in recent decades in terms of application range and usage quantity. , Polyurethane synthetic leather has soft luster, natural, soft touch, leather-like appearance, excellent bonding performance with substrate, anti-abrasion, flex resistance, anti-aging, anti-mold and other excellent properties. It has the advantages of good cold resistance, breathability, washability, convenient processing, and low price. It is the most ideal substitute for natural leather. [0003] Generally, thermosetting matrix resins are used to produce fiber-reinforced composite materials, and thermosetti...
