Embodiment Construction

[0026] The present invention is described in detail below in conjunction with embodiment and relevant figure, table. However, the invention is not limited to the examples given.

[0027] An embodiment of surface lipophilic modification treatment of aluminum oxide nanopowder with stearic acid. The method is: first dissolve 2.5g of stearic acid in 100g of xylene, add 10g of aluminum oxide, stir at a high speed of 5000 rpm in a self-made four-port flat-bottomed glass reaction vessel, and heat up to 100°C. React for 1 hour. After the reaction is completed, separate in a centrifuge at 4000 rpm for 10 minutes, pour off the supernatant, wash with toluene, and then separate by centrifugation at 4000 rpm, remove the supernatant, wash three times, and place in an oven at 80 ° C. Medium, bake for 5 hours, seal and store for later use.

Abstract

An antiwear transparent nano-class composite paint includes the dual-component composite paint consisting of high-molecular resin as filming material, Al2O3 nanoparticles, assistant, solvent, diluent and solidifying agent and the single-component composite paint consisting of high-molecular water resin, Al2O3 nanoparticles, assistant, and water. Its advantages are high adhesion and high ultraviolet shielding power.

Description

technical field [0001] The invention relates to a nano transparent wear-resistant composite paint which can be applied to the surface of resin, metal and wood. Background technique [0002] Researching a kind of transparent wear-resistant paint that can be applied to resin, metal and wood surfaces to improve the wear resistance and aging resistance of transparent resin or wooden floors and furniture surfaces is the goal that the paint industry has been pursuing at home and abroad. Existing patent application for this reason, as application number is the Chinese patent " wear-resisting paint " of 95101913.9, has adopted a kind of polyfunctional acrylate polymer etc. to make wear-resisting floor paint, but what used in this paint component is colloid Silica, which has limited wear resistance. [0003] The world patent WO0245129 (transparent wear-resistant coating containing surface-modified nano-powder) describes a preparation method of a transparent wear-resistant coating co...
