Embodiment 1
[0036] (1) Organic acid pretreatment
[0037] At 85°C, use 60wt% citric acid aqueous solution reflux technology to process waste hydrogenated silicon-butadiene rubber particles with a particle size of 100 μm containing AO-60 antioxidant. The proportion of hydrogenated silicon-butadiene rubber particles and citric acid aqueous solution is 1g: 20mL, suction filter after 5h, wash the hydrogenated silicon-butadiene nitrile rubber particles, and dry naturally for 20h after reaching neutrality.
[0038] (2) Preparation of vegetable oil-based polyurethane prepolymer
[0039] Weigh 100 parts by weight of soybean oil-based polyol with a hydroxyl value of 110 mgKOH / g, and add 10 parts by weight of naphthalene diisocyanate, wherein the molar ratio of isocyanate to hydroxyl is 1:2. Under nitrogen protection, stirring and reacting for 1 hour at room temperature, then raising the temperature to 80° C. at 2° C. / min, and ending the reaction after 2 hours. The stirring speed was 500 rpm to obta...
Embodiment 2
[0043] The method and raw material of present embodiment and embodiment 1 are basically the same, and difference is: the waste and old hydrogenated silicon nitrile rubber particle of AO-60 antioxidant is replaced with the waste and old hydrogenated silicon butadiene rubber that does not contain AO-60 antioxidant Particles, the mass ratio of vegetable oil-based polyurethane prepolymer, epoxy resin, hydrogenated silicon-butadiene rubber particles, curing agent, diluent and curing adjustment assistant is 10: 2: 0.5: 1.3: 0.2: 0.02, to obtain soybean oil-based Polyurethane / epoxy resin runs through the network structure polymer B.
Embodiment 3
[0045] The method and raw materials of this embodiment and embodiment 1 are basically the same, the difference is: soybean oil-based polyol is replaced by palm oil-based polyol-based polyol, vegetable oil-based polyurethane prepolymer, epoxy resin, hydrogenated silicon butyronitrile The mass ratio of the rubber particles, the curing agent, the diluent and the curing adjustment aid is 10: 1.5: 0.3: 1.2: 0.1: 0.01, and the palm oil-based polyurethane / epoxy resin interpenetrating network structure polymer C is obtained.
