Problems solved by technology

[0005] The main technical problem to be solved by the present invention is to provide a shock-resistant and shock-absorbing rubber material in view of the problems that the existing shock-absorbing rubber materials have poor impact resistance and aging resistance, are prone to fatigue, and have poor heat resistance and wear resistance. The preparation method of the method, the method firstly stirs magnesium chloride, surfactant OP-10, white carbon black, carbon black, etc. and ultrasonically oscillates, then adds ammonia water and stands for filtration, washes the filter residue to obtain a core-shell structure composite material, and dries it And calcined to obtain reinforcing filler, then mix natural rubber, eucommia gum, butadiene rubber, heat and mix with stearic acid, anti-aging agent, accelerator, etc., then add reinforcing filler and silane coupling agent to make The mixed rubber material is obtained, and finally the rubber material is made into rubber strips and vulcanized to obtain the impact-resistant and shock-absorbing rubber material. The preparation process of the present invention is simple and convenient, and the prepared shock-absorbing rubber material has higher impact strength. Excellent shock absorption and wear resistance, and the material is not easy to age and deform, which greatly improves the practicality and prolongs the service life of the material, and has broad market application prospects

Abstract

The invention discloses a preparation method of an anti-impact damping rubber material and belongs to the technical field of preparation of rubber materials. The method includes the steps of: 1) stirring magnesium chloride, a surfactant OP-10, white carbon black, carbon black and the like and performing ultrasonic vibration, adding ammonia water and allowing the mixture to stand, and filtering the mixture and washing a filter residue to obtain a core-shell structure composite material; 2) drying and calcining the composite material to obtain a reinforcing filler, and mixing natural rubber, eucommia ulmoides gum and butadiene rubber, and heat-mixing the components with stearic acid, an anti-aging agent, an accelerant and the like, and adding the reinforcing filler and a silane coupling agent to mix the components to obtain a mixed rubber compound; and 3) finally shaping the mixed rubber compound into strips and vulcanizing the rubber strips to produce the anti-impact damping rubber material. The preparation method is simple. The anti-impact damping rubber material has high anti-impact strength, has damping function and excellent anti-wear property, is not liable to age and deform, is greatly improved in practicability and prolonged in service life, and has wide market application prospect.

Description

technical field [0001] The invention discloses a preparation method of a shock-resistant and shock-absorbing rubber material, which belongs to the technical field of rubber material preparation. Background technique [0002] Vibration is ubiquitous in real life, and the phenomenon of vibration cannot be ignored and is indispensable. People have been committed to the research of vibration generation, control and elimination. The vibration of all objects will produce sound. If there is no vibration, there will be no music. , Human beings are also unable to communicate verbally. But vibration also can produce many adverse effects to people's life, as: resonance can cause the damage of device, and noise can affect human's living environment etc. How to minimize the adverse effects of vibration on people is the direction of development and pursuit of current shock absorption technology. [0003] The core of shock absorption technology is to eliminate disturbing vibration or fin...
