58 results about "Thermogenesis" patented technology

Thermogenesis is the process of heat production in organisms. It occurs in all warm-blooded animals, and also in a few species of thermogenic plants such as the Eastern skunk cabbage, the Voodoo lily, and the giant water lilies of the genus Victoria. The lodgepole pine dwarf mistletoe, Arceuthobium americanum disperses its seeds explosively through thermogenesis.

Fatigue-resisting natural rubber nano composite material and preparation method thereof

The invention discloses a fatigue-resisting natural rubber nano composite material and a preparation method thereof. The preparation method is characterized by comprising the following steps of: carrying out mechanical intercalation on 100 parts of natural rubber and 1-7 parts of nano montmorillonoid, then adding 4-8 parts of vulcanizing activator, 1-4 parts of anti-aging agent, 15-50 parts of carbon black packing, 0.5-3 parts of vulcanizing accelerator and 0.5-3 parts of vulcanizing agent, then adding gelatine into a flat-plate vulcanizing machine, and carrying out mould pressing for 10-30 minutes with the temperature of 135-155 DEG C and the pressure of 10-15MPa to obtain the fatigue-resisting natural rubber nano composite material. The invention substitutes the traditional high-structure carbon black packing by adopting the organic nano montmorillonoid, reduces the thermogenesis of the material under the dynamic loading effect and the same hardness by adopting less packing usage amounts, effectively prevents internal cracks of the material from generating and expanding by utilizing the layered structure of the nano montmorillonoid, and obtains a series of natural rubber materials with excellent fatigue-resisting performance without sacrificing the tensile breaking strength and the breaking elongation ratio of the material at the same time.

Preparation method for high-performance and low-thermogenesis SSBR rubber

The invention belongs to the field of machine manufacturing, and particularly relates to a preparation method for high-performance and low-thermogenesis SSBR rubber. The SSBR rubber is processed by SSBR 2305 base rubber, SSBR 312 rubber material, new carbon black, auxiliary agents and a vulcanization system, wherein the auxiliary agents comprise an anti-aging agent, an accelerant, nano-Zno, A151, and Mg(OH)2; the SSBR 2305 base rubber and the SSBR 312 rubber material are mixed. The preparation method comprises the following steps: adding the auxiliary agents into the mixed rubber materials of the SSBR 2305 base rubber and the SSBR 312 rubber material and stirring for 35 min; adding 50 phr of the new carbon black into the mixed rubber materials of the SSBR 2305 base rubber, the SSBR 312 rubber material and the auxiliary agents, and uniformly stirring; adding the mixed rubber materials of the SSBR 2305 base rubber, the SSBR 312 rubber material, the auxiliary agents and the new carbon black into the sulfur-free vulcanization system to be subjected to vulcanization for 50 minutes, wherein the temperature of the vulcanization system is 150 DEG C. According to the invention, the production efficiency is high, the product percent of pass is high, the physical and mechanical properties are excellent, the low-thermogenesis performance is excellent, and the application prospect is wide.
