Embodiment 1
[0051] A preparation method of a composite rubber pad, comprising the following steps:
[0052]Step1, mix natural rubber, nitrile rubber, tetrapropylene fluorine rubber, sodium stearate, triallyl isocyanurate, polyvinylidene fluoride, methylol fatty amine, dicumyl peroxide, titanic acid Ester coupling agent, filler and plasticizer are poured into a pressurized rubber kneader, pressed at 120-130°C for 10 minutes, and discharged to obtain mixture A;
[0053] Step2, add nickel-based alloy, far-infrared ceramic powder, titanium alloy, aminosilane and thermoplastic polyurethane elastomer into the ultrasonic disperser for dispersion, the ultrasonic power is 180-200W, the dispersion time is 15-20 minutes, and the dispersion temperature is 120- 140°C, mixture B was obtained;
[0054] Step3, fully stir the mixture A and the mixture B evenly, then pour into the internal mixer, under the condition of 140-150 ℃, banbury at the speed of 800-950 rpm for half an hour, to obtain the mixture ...
Embodiment 2
[0067] A sound-absorbing and anti-wave wall structure, comprising a dam foundation 1, the water-facing surface of the dam foundation 1 is an inclined surface, and several inclined rubber pads 2 are arranged on the water-facing surface of the dam foundation 1, and the inclined rubber pads 2 are arranged in parallel at equal intervals, The inclined rubber pad 2 is axially connected to the steel plate 3 below it, and the right end of the steel plate 3 is fixed inside the dam foundation 1. The inclined rubber pad 2 is provided with evenly distributed through holes 4, and the adjacent inclined rubber pads The top of 2 is connected by a spring 5. The top of the dam foundation 1 facing the water is provided with a wave-proof wall 6. A semicircular arc-shaped anti-wave cover 7 with an opening downward is provided.
[0068] Further, the water-facing surface of the dam foundation 1 is tangent to the water-facing surface of the anti-wave wall 6 .
[0069] Further, the water-facing surfa...
