Abstract

The invention provides sponge foaming rubber for a car door sealing strip and a preparation method thereof, a car door sealing strip and a preparation method thereof. The sponge foaming rubber for the car door sealing strip, provided by the invention, is prepared from the following components in parts by weight: 20 to 40 parts of ethylene-propylene-diene monomer 9090M, 69 to 92 parts of ethylene-propylene-diene monomer V8800, 5 to 7 parts of active zinc oxide, 1 to 2 parts of stearic acid, 1 to 3 parts of a dispersant, 0.8 to 1.4 parts of erucamide, 1 to 2 parts of PEG-4000 (Polyethylene Glycol-4000), 5 to 10 parts of POE (Polyolefin Elastomer), 60 to 77 parts of paraffin oil R-2291, 30 to 50 parts of carbon black N550, 50 to 70 parts of carbon black SP5000, 1.5 to 2.5 parts of sulfur S-80, 6 to 10 parts of a moisture absorbent GR, 3 to 6.4 parts of an accelerant, 3 to 3.6 parts of a foaming agent OBSH-75 (Oxydibenzenesulfonyl Hydrazide-75) and 1.1 to 1.5 parts of a foaming agent AC3000-75. By adopting a formula of the sponge foaming rubber for the car door sealing strip, provided by the invention, the prepared sponge rubber has relatively low density and can meet a lightweight design; meanwhile, the obtained rubber also can have relatively good physical performance, so that the utilization quality of the car door sealing strip utilizing the sponge foaming rubber can also be improved.

Description

technical field [0001] The invention relates to the technical field of automobile sealing strips, in particular to a sponge foam rubber material for the sealing strips of automobile doors. The invention also relates to a preparation method of the foamed rubber material for the door sealing strip, a door sealing strip using the foamed rubber material for the door sealing strip, and a preparation method for the door sealing strip. Background technique [0002] The car door seal strip mainly plays the role of sealing, dustproof, waterproof and decoration, and it is installed on the sheet metal around the car door. When the car door is closed, the sealing effect is realized by the bonding between the sealing strip and the door frame, so as to prevent external wind, rain, dust and other harmful substances from invading the car, and reduce the risk of damage to the doors and windows when the car is running. Generates vibrations to maintain a sense of cleanliness and comfort and r...
