example 1

[0021]In parts by weight, put 10 parts of white carbon black, 8 parts of carbon black, 5 parts of silver nitrate, 5 parts of ammonium chloride, and 40 parts of water in a ball mill for ball milling and mixing for 50 minutes to obtain No. 1 mixed solution; In total, 30 parts of acrylonitrile, 8 parts of azobisisobutyronitrile, 8 parts of n-pentane, and 8 parts of methyl methacrylate were placed in No. 1 beaker, and No. 1 beaker was placed in an ultrasonic disperser. Under the condition of ultrasonic frequency of 75kHz, mix ultrasonically for 50 minutes to obtain No. 2 mixed solution; put No. Shear at low temperature and high speed for 10 minutes to obtain a homogeneous mixed solution, then place the homogeneous mixed solution in a high-pressure reactor, and fill the reactor with nitrogen at a rate of 90 mL / min. After 50 minutes of nitrogen heat preservation and pressure reaction, after the temperature in the high-pressure reactor was lowered to room temperature, the valve was o...

[0025] In parts by weight, put 20 parts of rice husk fiber, 3 parts of secondary sedimentation tank sludge, 0.5 part of sucrose, and 30 parts of water in a fermentation tank, and stir and mix at a temperature of 35°C and a speed of 200r / min. Ferment for 5 days, then add 0.3 times the mass fraction of rice husk fiber to the fermenter and ferric chloride solution with a mass fraction of 20%, stir and mix for 60 min at a rotating speed of 500r / min, then add 30% ferric chloride to the fermenter % ammonia water to adjust the pH to 8.3 to obtain a mixed slurry, then filter the mixed slurry, filter the residue, then wash the filter residue 8 times with deionized water, then place the washed filter residue in an oven at a temperature of 110°C Then, put the dried filter residue in a carbonization furnace, and fill the furnace with nitrogen gas at a rate of 130mL / min, and keep warm and carbonize for 3 hours at a temperature of 1150°C to obtain pretreated rice. Hull fiber: put the pretre...

Abstract

The invention discloses a method for preparing a rubber shock pad, which belongs to the technical field of a high-molecular material. The method comprises the following steps: mixing rice husk fiber,secondary sedimentation tank sludge, sucrose and water, performing fermentation, adding a ferric chloride solution, stirring and mixing the materials, adding ammonia water to adjust the pH, and performing steps of filtering, washing, drying, and heat-insulating carbonization to obtain pretreated rice husk fiber; performing high temperature treatment on the pretreated rice husk fiber by steam, anddrying the material to obtain modified rice husk fiber; masticating the hydrogenated nitrile rubber, then adding natural resin, the modified rice husk fiber, a modified additive, a vulcanizing agent,an accelerator, an anti-aging agent, and a plasticizer for mixing, applying an external magnetic field during a mixing process, and after mixing is completed, performing extrusion molding, vulcanization, and discharging to obtain the rubber shock pad. The rubber shock pad produced by the technical scheme of the invention has the characteristics of excellent shock absorption performance and aging resistance.

Description

technical field [0001] The invention discloses a preparation method of a rubber shock absorber, which belongs to the technical field of polymer materials. Background technique [0002] With the rapid development of modern industry today, vibration has become a problem that seriously affects various fields. For example, environmental vibration endangers the safety and stability of buildings, especially high-rise buildings. Industrial vibration affects the accuracy of equipment and instruments. The consequences of some vibrations will directly It poses a huge threat to personal and property safety. Reducing or eliminating the vibration of the vibration source is the most fundamental and best way to eliminate the vibration, but from the actual situation, the vibration cannot be completely eliminated, so other ways should be used. At present, in the industry, the main method is to apply various shock-absorbing products, and rubber shock-absorbing products are an important part ...
