Embodiment 1
[0032] As shown in Figure 1, a kind of preparation method of the resin-based composite material containing metal particle, it comprises the steps:
[0033] 1) W particle surface modification treatment: W powder (average particle size 0.95μm, Chaozhou Xianglu Tungsten Industry Co., Ltd.), silane coupling agent (KH550, molecular formula N 2 N(CH 2 ) 3 Si(OC 2 h 5 ) 3 , Hubei Wuhan University Organosilicon New Materials Co., Ltd.) and ethanol (Shanghai Sinopharm Chemical Reagent Company) are mixed, wherein KH550 silane coupling agent is 2wt% of W powder, and the weight ratio of ethanol and W powder is 1: 1; Stir with a stirrer and a sonicator for 10 min, and heat to reflux at 100°C (N 2 protection), forming a suspension (metal particle suspension of grafted surface modifier).
[0034] 2) Classification: classify the suspension to obtain a suspension containing particles of a single particle size, the classification time is 2min, suction filter the suspoemulsion containing p...
Embodiment 2
[0038] A method for preparing a resin-based composite material containing metal particles, comprising the steps of:
[0039] 1) Surface modification of Mo particles: Mix Mo powder (average particle size 1.50 μm, Beijing General Research Institute for Nonferrous Metals), KH550 silane coupling agent and ethanol, wherein KH560 silane coupling agent is 2wt% of Mo powder, ethanol The weight ratio with Mo powder is 1: 1; at the same time, use a stirrer and a sonicator to vibrate and stir for 10min, and heat to reflux at 100°C (N 2 protection), forming a suspension.
[0040] 2) Classify the suspension to obtain a suspension containing particles of a single particle size, the classification time is 1 min, and filter the suspoemulsion to obtain a modified Mo powder (metal powder grafted with a surface modifier) with a single particle size.
[0041] 3) Add the modified Mo powder in step 2) into the epoxy resin, mix the modified Mo powder and the epoxy resin according to the weight rati...
