nano Al2O3Introduction: 
The tensile strength, heat resistance, aging resistance and wear resistance of rubber can be significantly enhanced by adding nano-aluminum trioxide (L07X) into rubber.
Experiments show that the tensile strength of rubber is not very high when nano-alumina is added only, but the heat resistance, aging resistance, fatigue resistance and wear resistance of rubber are better than those of silicon oxide rubber only. The tearing strength and tensile strength of the rubber were improved after the nano-alumina and nano-silica were used together. The tensile strength of the rubber was higher than that of the rubber with nano-alumina or silicon oxide only. When the mass ratio of nano alumina and nano silica is 1:1, the maximum tensile strength of rubber can be achieved. When the mass ratio of nano-alumina to nano-silica is 3:1, the rubber has the best wear resistance and fatigue resistance.
Nano-alumina is used in various rubber and rubber industries. It can also make rubber have good thermal conductivity, corrosion resistance, and give rubber better compactness and friction resistance.
Nano-alumina has a relatively high thermal conductivity, filling in rubber can give rubber thermal conductivity and insulation, and make it have good physical and mechanical properties.
Tang Mingming et al, 100 phr of nano-alumina and 200 phr of micro-alumina were filled into styrene-butadiene rubber to prepare heat conductive rubber with good comprehensive properties, the thermal conductivity of the material can reach 0.901W / (m K).
High thermal conductivity silicone rubber can be prepared by filling homogeneous nano-Al2O3 into silicone rubber. A large number of alumina particles in high temperature vulcanized silicone rubber are bonded to the rubber matrix, which makes it have better thermal conductivity and corrosion resistance than room temperature vulcanized silicone rubber.
Silicone rubber filled with nano-Al2O3 can be used to fabricate the thermal conductivity layer of electronic components. With the increase of filler content, the thermal conductivity of silicone rubber increases and the thermal expansion coefficient decreases.
