Embodiment 1
[0072] Manufacture push pin 3-7 of the present invention according to the following steps, and by mass percentage:
[0073] Step 1: Add 1% of 2-methyl-undecanol in the proportioning components to the batch reactor according to the mass percentage, and add 5% ultrapure water at the same time, start the mixer in the batch reactor, and set the speed 1rpm;
[0074] Step 2: After the batch reactor runs for 5 minutes, add 3% modified auxiliary additive and 1,1'-(1-methylethylene)bis[4-(2-propenyloxy)]benzene 6 %, start the steam seal steam decompression heater in the batch reactor, raise the temperature to 3°C, add 9% of coagulation accelerator and 2% of iron nanoparticles, stir evenly in the batch reactor, and obtain the S component homogenate;
[0075] Step 3: Take 4% of the coagulation-promoting catalyst in the proportioning component according to the mass percentage, mix and stir with the S component homogenate, start the steam seal steam decompression heater in the batch reac...
Embodiment 2
[0077] Manufacture push pin 3-7 of the present invention according to the following steps, and by mass percentage:
[0078] Step 1: Add 87% of 2-methyl-undecanol in the proportioning components into the batch reactor according to the mass percentage, and add 86% of ultrapure water at the same time, start the mixer in the batch reactor, and set the speed 87rpm;
[0079] Step 2: After the batch reactor has been running for 86 minutes, add 28% of modified additives and 1,1'-(1-methylethylene)bis[4-(2-propenyloxy)]benzene 38 %, start the steam seal steam decompression heater in the batch reactor, raise the temperature to 78°C, add 29% of coagulation accelerator and 95% of iron nanoparticles, stir evenly in the batch reactor, and obtain the S component homogenate;
[0080] Step 3: Weigh 20% of the coagulation-promoting catalyst in the proportioning component according to the mass percentage, mix and stir with the S component homogenate, start the steam seal steam decompression he...
Embodiment 3
[0082] The use effects of the push pins 3-7 prepared in Examples 1-2 and the same parts obtained in the comparative example were compared. The high-speed heat distortion temperature, extrusion strength, number of fractures per thousand hours, and wear rate of the two materials were counted, and the results are shown in Table 1.
[0083]
[0084] As can be seen from Table 1, push pin 3-7 of the present invention, its above-mentioned performance index is all better than the product that prior art produces.
