[0098] "-" in Table 1 indicates that the dosage is "0".

Embodiment 1～6

[0100] Embodiments 1 to 6, the raw material components of each embodiment in Table 1 are obtained according to the following preparation steps to obtain the product of each embodiment (the parameters of each step are as shown in Table 2):

[0101] (1) Pre-plasticize the natural rubber with a internal mixer, and use the open mixer to produce a sheet with a thickness of 3mm, and use it within 4-12 hours; mix the natural rubber and neoprene with an internal mixer to obtain a mixture A ;

[0102] (2) Continue to input activator zinc oxide, magnesium oxide, stearic acid, anti-aging agent, protective wax, tackifier mixing to internal mixer, get mixture B;

[0103] (3) Continue to drop into the internal mixer carbon black, precipitated silica, and plasticizer for mixing, then carry out glue removal and sheet discharge to obtain rubber premix;

[0104] (4) Put the rubber premixed rubber to rest, then put the rubber premixed rubber after standing still into the internal mixer for mast...

Abstract

The invention discloses a natural rubber-neoprene composition material as well as a preparation method and application thereof. The raw material composition of the natural rubber-neoprene compositionmaterial comprises the following components in parts by weight: 85-95 parts of natural rubber, 5-15 parts of neoprene, 4-10 parts of an activator A, 0.5-2 parts of an activator B, 2-6 parts of an anti-aging agent, 2-4 parts of protective wax, 1-3 parts of a tackifier, 10-20 parts of carbon black, 3-8 parts of white carbon black, 1.2-1.7 parts of a vulcanizing agent, 0.2-0.5 parts of an acceleratorA, and 1.2-2.5 parts of an accelerator B. The rubber composition material provided by the invention is applied to a hydraulic suspension main spring material, and has the characteristics of low damping, excellent mechanical properties, widest temperature resistance range, small high-temperature creep deformation, good shear fatigue resistance, and long endurance life; and meanwhile, the preparation method of the rubber composition material provided by the invention is simple in steps and convenient to operate, and is suitable for industrial production.

Description

technical field [0001] The invention specifically relates to a natural rubber-chloroprene rubber composite material, its preparation method and application. Background technique [0002] The engine is a vibration source body and also a heating body. The engine and the subframe are not directly connected, but are flexibly connected through the engine mount (hereinafter referred to as "mount"). The suspension fixes and supports the engine and must have sufficient rigidity to withstand the dead weight of the engine assembly and the rotational torque generated by the output power. The two-way vibration isolation of the mount not only attenuates the transmission of vibration from the engine to the car body, but also attenuates the transmission of vibration from the road to the engine. The mount and its materials must also be suitable for various harsh working conditions, such as low temperature, high temperature, heat radiation, sun exposure, ozone erosion, etc. For the suspen...
