Embodiment 1
[0024] The preparation process of the water-resistant and wear-resistant two-component resin adhesive comprises the following steps:
[0025] Step 1, A component adhesive: (1), according to the volume ratio of 1:1, measure ammonia water and ethanol, mix to prepare mixture A, then add tetraethyl orthosilicate whose volume is three times the volume of mixture A, stir for 4.5 After h, add it to the disperser, disperse for 20min under the condition of 18000rpm, let it stand for 2h, and prepare the suspension, and set aside;
[0026] (2) Add 3-aminopropyltriethoxysilane whose volume is 0.7 times the volume of ammonia water to the suspension, stir for 17 hours to form a mixture B, reflux the mixture B at 90°C for 0.9 hours, centrifuge and filter with suction , drying the filtered residue at 65° C. to prepare nanoparticles for subsequent use;
[0027] (3) According to the weight ratio of 10:9:1.2, weigh the polyamide, epoxy resin and the prepared nanoparticles respectively, mix the ...
