Shock pad for air conditioner outdoor unit and preparation method of shock pad

Abstract

The invention discloses a shock pad for an air conditioner outdoor unit, which relates to the technical field of rubber and is prepared from the following raw materials in parts by weight: 50-60 parts of natural rubber, 25-40 parts of ethylene propylene diene monomer, 20-25 parts of fluororubber, 20-30 parts of carbon black N326, 2-8 parts of zinc oxide, 1-5 parts of stearic acid, 1-5 parts of anti-aging agent RD, 10-15 parts of diatomite, 2-8 parts of silane coupling agent, 8-12 parts of attapulgite, 20-40 parts oflight calcium carbonate, 1-6 parts of microcrystalline wax, and 1-3 parts of anaccelerant. The invention further discloses a preparation method of the shock pad, the preparation method comprises the steps of raw material preparation, primary mixing, secondary mixing, punching and chamfering and the like, the produced shock pad product has excellent oxidation resistance and corrosion resistance by adding the ethylene propylene diene monomer, and meanwhile, the shock pad product has excellent oxidation resistance and corrosion resistance; the fluororubber is combined with other components, so that certain tensile strength, wear resistance and fatigue resistance are achieved.

Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to a shock-absorbing pad for an external air-conditioner and a preparation method for the shock-absorbing pad for an external air-conditioner. Background technique [0002] Rubber damping pads are widely used in machinery, home appliances, automobiles and other fields. Shock absorbing pads are the most common auxiliary damping components. They are simple in structure, easy to manufacture, and low in cost, so they can meet most of the vibration damping requirements. At present, the shock absorbing pads used for air conditioner external units are required to have excellent fatigue resistance and wear resistance, and because of the large demand for this kind of shock absorbing pads, the current punching method is punching multiple single products, and the production efficiency is low. Low, and after punching, it is necessary to use chamfering equipment to chamfer the mountin...

Problems solved by technology

At present, the shock absorbing pads used for air-conditioning external units are required to have excellent fatigue resistance and wear resistance, and because of the large demand for this type of shock absorbing pads, the current punching method is punching multiple single products, and the production efficiency is low. Low, and after punching, it is necessary to use chamfering equipment to chamfer the mounting hole, and the product frequently changes stations, which takes a long time
