Problems solved by technology

However, the patented method has defects such as complicated process flow and difficulty in industrialized production, and does not meet the conditions for large-scale industrialized production
Moreover, in these methods, simply physically mixing or impregnating epoxy resin and MXene cannot effectively combine the two materials, and cannot effectively improve the various properties of epoxy resin.

[0038] Preparation example TiO 2 / Ti 3 C 2 Preparation of nanocomposites

preparation example 1

[0040] 1) Add 1.25mmol of TBOT into 10mL ethanol solution, stir for 1h, and obtain TiO 2 Precursor solution; 2.5mmol of Ti 3 C 2 The powder was added to 30mL water and ethanol mixed solvent (the volume ratio of water and ethanol was 1:1), and ultrasonically dispersed for 0.5h to obtain Ti 3 C 2 Dispersion; TiO will be obtained 2 The precursor solution was slowly added dropwise to the Ti 3 C 2 In the dispersion liquid, stir vigorously at room temperature for 2 hours to obtain a uniform mixed solution;

[0041] 2) Transfer the mixed solution obtained in step 1) to a polytetrafluoroethylene liner, seal the autoclave, and react at 160° C. for 24 hours;

[0042] 3) After the reaction in step 2) is completed and cooled naturally, the powder obtained by the reaction is collected by centrifugation at 6000r / min, and then washed with deionized water and absolute ethanol respectively, and then the washed powder is placed in a vacuum drying oven at 60°C After drying for 12 hours, t...

Abstract

The invention provides an abrasion-resistant and ultraviolet-aging-resistant epoxy composite material and a preparation method thereof. The abrasion-resistant and ultraviolet-aging-resistant epoxy composite material is prepared from the materials of an epoxy resin matrix material and a TiO2 / Ti3C2 nano-composite material uniformly dispersed in the epoxy resin matrix material, wherein the TiO2 / Ti3C2nano-composite material accounts for 0.1-3 wt% of the epoxy resin matrix material, and the epoxy composite material is obtained by curing the TiO2 / Ti3C2 nano-composite material and epoxy resin in thepresence of a quaternary ammonium salt. The preparation method of the epoxy composite material is simple, and raw materials are easily available. The abrasion-resistant and ultraviolet-aging-resistant epoxy composite material prepared by the preparation method has a lower abrasion rate than ordinary epoxy materials, and meanwhile the ultraviolet-aging resistance is excellent, the tensile strengthis further improved to a certain extent, and the abrasion-resistant and ultraviolet-aging-resistant epoxy composite material is particularly suitable for being used in abrasion-resistant devices, such as the manufacture of abrasion-resistant automotive parts and abrasion-resistant sports equipment.

Description

technical field [0001] The invention belongs to the field of epoxy resin composite materials, and in particular relates to a wear-resistant and anti-ultraviolet aging epoxy composite material and a preparation method thereof. Background technique [0002] Epoxy resin is a kind of thermosetting polymer with excellent mechanical properties, electrical insulation and chemical stability. As the matrix resin of reinforced composite materials, it has been widely used in engineering fields such as aerospace, automobile and electrical and electronic. However, the inherent three-dimensional network structure of epoxy resin makes it exhibit poor wear resistance. Moreover, if it is used under ultraviolet light for a long time, the epoxy resin is prone to aging and degradation. Therefore, improving the wear resistance and UV aging resistance is of great significance for the practical application of epoxy resins. [0003] Adding organic or inorganic wear-resistant fillers to epoxy resi...
