Problems solved by technology

[0005] However, the anti-wave wall is in an open-air environment. Ordinary rubber materials are prone to aging after being exposed to wind, rain, and sun, which shortens their service life. Further, ordinary rubber materials are very resistant to seawater corrosion and sand and stone friction. Difference

Abstract

The invention discloses a preparation method for a composite rubber mat. The composite rubber mat comprises the following main raw materials: natural rubber, butadiene-acrylonitrile rubber, Aflas, nickel-based alloy, sodium stearate, triallyl isocyanurate, polyvinylidene fluoride, far-infrared ceramic powder, hydroxymethyl fatty amine, titanium alloy, amino silane, thermoplastic polyurethane elastomer, dicumyl peroxide, a titanate coupling agent, a heat-aging resisting agent, a light-aging resisting agent, a vulcanizing agent, an acid-resistant additive, a salt-resistant additive, a filler anda plasticizer. The invention adopts reasonable raw materials and proportions, and each component complements each other and acts synergistically, so the composite rubber mat has the characteristics of acid resistance, salt resistance, heat aging resistance, light aging resistance and abrasion resistance, has long service life in an open air environment and presents good usage effect when cooperated with a wave wall.

Description

technical field [0001] The invention relates to the technical field of anti-aging materials, in particular to a preparation method of a composite rubber pad. Background technique [0002] In order to prevent seawater waves from crossing the crest of the dam, anti-wave walls are generally installed on the top of the dam. Most of the existing anti-wave walls adopt vertical wall structures. This structure collides with the waves head-on, and often splashes high waves and water mist. Under the action of the wind, the waves and water mist will still cross the top of the wall, which will have an adverse impact on the environment behind the dam. If this type of vertical anti-wave wall is to be used to completely prevent waves, the anti-wave wall must be built very high. Like this project cost will improve greatly, has increased cost. Moreover, the impact of the existing vertical anti-wave wall with waves also produces a lot of noise. [0003] Further, the existing dams are not eq...
