Examples
Embodiment 1
[0049] Example 1: Take 40 parts of A component, 20 parts of B component, and 1 part of C component in three batches and add them to the stirring and defoaming device in turn, and stir and mix at a speed of 2800r / min for 25 minutes; then take 0.2 parts of F component Add it into the stirring and defoaming device, continue to stir and mix at a speed of 2800r / min for 20min, finally add 1 part of D and 1 part of E in two batches, stir and mix at a speed of 2800r / min for 15min, and keep the stirring and defoaming device at a speed of 1200r / min Min to stir, control the vacuum in the stirring and defoaming device to -0.1Mpa, defoam the mixed components for 35min, keep the temperature at 20°C, keep the humidity at 40%, and fill the glue until it is black in a dark environment. light hose.
Embodiment 2
[0050] Example 2: Take 45 parts of A component, 22 parts of B component, and 1.5 parts of C component in three batches and add them to the stirring and defoaming device in turn, and stir and mix at a speed of 2800r / min for 25 minutes; then take 0.4 parts of F component Add it into the stirring and defoaming device, continue to stir and mix at a speed of 2800r / min for 20min, finally add 1.3 parts of D and 2 parts of E in two batches, stir and mix at a speed of 2800r / min for 15min, and keep the stirring and defoaming device at a speed of 1200r / min Min to stir, control the vacuum in the stirring and defoaming device to -0.1Mpa, defoam the mixed components for 35min, keep the temperature at 20°C, keep the humidity at 40%, and fill the glue until it is black in a dark environment. light hose.
Embodiment 3
[0051] Example 3: Take 50 parts of A component, 24 parts of B component, and 2 parts of C component in three batches and add them to the stirring and defoaming device in turn, and stir and mix at a speed of 2800r / min for 25 minutes; then take 0.6 parts of F component Add it into the stirring and defoaming device, continue to stir and mix at a speed of 2800r / min for 20min, finally add 1.6 parts of D and 3 parts of E in two batches, stir and mix at a speed of 2800r / min for 15min, and keep the stirring and degassing device at a speed of 1200r / min Min to stir, control the vacuum in the stirring and defoaming device to -0.1Mpa, defoam the mixed components for 35min, keep the temperature at 20°C, keep the humidity at 40%, and fill the glue until it is black in a dark environment. light hose.
