Abstract

The invention relates to an EPDM (Ethylene-Propylene-Diene Monomer) white sponge strip for an automobile air conditioner. The EPDM white sponge strip is prepared from the following materials in part by weight: 100 parts of EPDM K4903 crude rubber, 20 to 30 parts of white carbon black, 80 to 100 parts of silica, 70 to 90 parts of white oil, 15 to 20 parts of titanium dioxide, 5 to 8 parts of zinc oxide, 1 to 2 parts of stearic acid, 2 to 4 parts of PEG4000 (polyethylene glycol 4000), 2 to 3 parts of dispersing agent, 1 to 3 parts of coupling agent, 0.01 part of carbon black N550, 3 to 5 parts of calcium oxide, 1 to 2 parts of MBT-80, 1 to 2 parts of ZDBC-80, 0.5 to 0.8 part of TDEC-75, 3 to 5 parts of AC-75, 3 to 5 parts of OBSH (oxybis benzene sulfonyl hydrazide), 1 to 2 parts of DTDM (4,4'-Dithiodimorpholine) and 1 to 2 parts of S-80. The invention further provides a preparation method of the EPDM white sponge strip. The EPDM white sponge strip and the preparation method have the advantages that the EPDM white sponge strip disclosed by the invention has high tensile strength, low voltage violation and foaming density and excellent performance; a foaming structure is formed inside the EPDM white sponge strip, so that the EPDM white sponge strip has better heat insulation performance and sound adsorption and noise reduction effect.

Description

technical field [0001] The invention relates to an EPDM white sponge strip, in particular to an EPDM white sponge strip for an automobile air conditioner and a preparation method thereof. Background technique [0002] EPDM sponge strip has low density, excellent elasticity and flexibility, and has good shock absorption, sound insulation, and heat insulation properties. Because of its excellent heat retention, it can be used in car air conditioners. [0003] EPDM sponge strips used in automotive air conditioners generally require high tensile strength, small pressure change and foam density, while EPDM sponge strips are generally black, and white EPDM sponge strips are more difficult to develop because of their technical difficulty. Use less. [0004] There is no report about the EPDM white sponge strip with high tensile strength, pressure change and low foam density. Contents of the invention [0005] The purpose of the present invention is to provide a kind of EPDM whi...
