AI Technical Summary

Problems solved by technology

On the one hand, the general rubber shock absorber is mainly made of natural rubber, and most of the natural rubber is not resistant to ozone, thus affecting the life of the rubber shock absorber
On the other hand, the rubber shock absorber supporting the cab has high requirements for ozone resistance, because the metal skeleton and rubber are bonded by vulcanization, and there is internal stress after bonding between the metal and rubber, which is prone to damage when the ozone concentration is high. Reaction, the rubber will undergo certain physical and chemical changes, and the force of the rubber molecules inside the entire shock absorber will change, resulting in tiny cracks around the rubber and metal bonding. Many cab support rubber shock absorbers often fail to meet the requirements of aging resistance, and various fatigue and damage phenomena appear, making the vehicle unsafe, which affects personal health and pollutes the environment

Abstract

The invention discloses an ozone-resisting supporting rubber vibration absorber of a truck cab and a preparation method of the ozone-resisting supporting rubber vibration absorber. The ozone-resisting supporting rubber vibration absorber comprises a rubber piece and a metal framework coated by a Chemlock adhesive. The rubber piece is formed by natural rubber, cis-polybutadiene, an ethylene propylene diene monomer, zinc oxide, stearic acid, N-cyclohexyl-2-benzothiazole sulphenamide, dicumyl peroxide, an anti-aging agent 4020, an anti-scorching agent, high-wear-resistance furnace black, dioctylphthalate, paraffin and sulfur. The preparation method comprises the following steps of: carrying out primary-section mixing and secondary-section mixing to obtain finally-mixed rubber; placing the metal framework coated by the Chemlock adhesive into a mould; and finally, placing the finally-mixed rubber into the mould, and injecting and vulcanizing through an injection machine under the conditions that the temperature is 150-170 DEG C, the time is 200-220 seconds and the pressure is 12-14 MPa to obtain the ozone-resisting supporting rubber vibration absorber. The ozone-resisting supporting rubber vibration absorber has the advantages of ozone resistance, anti-aging performance, high snapping strength, fatigue resistance, low cost and the like.

Description

technical field [0001] The invention relates to a rubber shock absorber, in particular to an ozone-resistant supporting rubber shock absorber for a truck cab; the invention also relates to a preparation method of the ozone-resistant supporting rubber shock absorber. Background technique [0002] The supporting rubber shock absorber set in the truck cab is mainly installed at the position of the turning mechanism of the cab to perform the functions of support and shock absorption. Rubber shock absorbers are used under dynamic conditions, and there are many types of aging, such as oxygen aging, ozone aging and fatigue aging, which are far more serious than static ones. Various aging factors not only act alone, but also in various ways Such coupling forms exert effects on rubber, such as mechanical factors (load, vibration conditions, etc.), often have the participation of oxygen, ozone and light in the atmosphere, and heat (temperature) and other phenomena, so the rubber formu...
