Preferably, the foam cell material, wherein: the high-elasticity rubber comprises 20-25 wt% of the meta-fluoroether rubber and 75-80wt% of the POE resin.
The polypropylene is the main component of the foam pore material, has chemical resistance, heat resistance, electrical insulation, high-strength mechanical property and good high-wear-resistance processing property, but is easy to age and degrade after the action of light, heat and oxygen to cause performance reduction and color change, has poor cold resistance and is easy to brittle fracture at low temperature.
Preferably, the foam cell material, wherein: the cross-linking agent is hexafluoroisobutylene-styrene-butadiene copolymer, the hexafluoroisobutylene content is 3-5 wt%, the styrene content is 23-25 wt%, and the balance is butadiene. The cross-linking agent used in the prior art is usually a styrene-butadiene copolymer, and the cross-linking agent has weak aging resistance and low cross-linking degree, so that the scheme modifies the styrene-butadiene copolymer, introduces hexafluoroisobutylene molecules into the styrene-butadiene copolymer, improves the aging resistance and the cross-linking degree of the styrene-butadiene copolymer on the premise of not influencing other properties, and researches show that the hexafluoroisobutylene-styrene-butadiene copolymer can be combined with high-elasticity rubber to further improve the aging resistance, and meanwhile, the toughness in the foam cell material can be obviously improved, so that the long-term impact strength of the foam cell material is improved; and when the proportion of the hexafluoroisobutylene, the styrene and the butadiene in the hexafluoroisobutylene-styrene-butadiene copolymer is limited, the better ageing resistance and impact resistance can be obtained, so the proportion of the hexafluoroisobutylene, the styrene and the butadiene is limited.
Preferably, the foam cell material, wherein: the filler comprises 74 to 78wt% of boron oxide, 12 to 169wt% of Al3BC3, 6 to 14wt% of calcium titanate.
