Problems solved by technology

[0003] In the prior art, rubber material is usually used for the casing of air-conditioning metal copper pipes, but due to insufficient rubber formula and preparation process, the performance of the air-conditioning hose is poor, and because the rubber material absorbs the purple light of the sun, the rubber material is easy to oxidize The additives and accelerators in the rubber material have different functional groups. These functional groups have groups

Abstract

The invention relates to an EPDM (ethylene-propylene-diene monomer) rubber for air conditioners and a preparation technique thereof. The rubber is prepared from the following components in parts by weight: 100 parts of EPDM unvulcanized rubber, 60-80 parts of carbon black N550, 30 parts of silica, 80-100 parts of paraffin oil, 6-8 parts of zinc oxide, 1-2 parts of stearic acid, 1-3 parts of PEG 4000, 5-8 parts of ointment, 5-8 parts of calcium oxide, 1-2 parts of BZ-80, 1-2 parts of MBT-80, 1-2 parts of CBS-80, 1-2 parts of TDEC-75, 2-5 parts of AC-75, 7-10 parts of OBSH and 1-2 parts of sulfur. The EPDM rubber for air conditioners has favorable formula; the product has excellent weather aging resistance; the formed product has closed foaming pores, and thus, has favorable thermal insulation function, shock absorptivity and energy saving property; and the preparation technique is simple.

Description

technical field [0001] The invention relates to the technical field of air conditioner rubber, in particular to an EPDM rubber material for an air conditioner and a preparation process. Background technique [0002] In the air conditioner, due to the form of heating and cooling, the air convection conducts heat and cold exchange, and the hot air will be liquefied into condensed water when it is cold. The metal copper tube is used to connect with the refrigeration system to facilitate the discharge of condensed water. Because the metal copper tube has Electrical conductivity requires an insulating air-conditioning hose to wrap the metal copper tube; considering that the metal copper tube is a hollow tube, the weight of the air-conditioning hose should not be too heavy. Hot air convection is easy to cause material aging; metal copper pipes are affected by the alternation of hot and cold temperatures, and their material properties are reduced. It is necessary for the air-condit...
