Embodiment 1
[0029] (1) 15 parts of PTMEG1000 (polytetrahydrofuran ether glycol with a functionality of 2 and a molecular weight of 1000), 51 parts of PTMEG2000 (polytetrahydrofuran ether glycol with a functionality of 2 and a molecular weight of 2000), 24.2 parts of EP330 (polytetrahydrofuran ether glycol with a functionality of 2, 3, polyoxypropylene triol with a molecular weight of 5000), 8.3 parts of BDO (1,4-butanediol), 0.31 parts of H 2 O, 1.03 parts of AK7703, 0.14 parts of BDMAE (bis(dimethylaminoethyl) ether) and 0.02 parts of T-12 (dibutyltin dilaurate) were mixed uniformly to obtain component A;
[0030]After mixing 50 parts of MDI (diphenylmethane diisocyanate), 30 parts of PTMEG1000 and 20 parts of PTMEG2000, under nitrogen protection atmosphere, stirred and reacted at 85°C for 4 hours to obtain component B with -NCO value of 13.39;
[0031] (2) According to the molar ratio of active -H in component A and -NCO group in component B: 1:1, component A preheated to 35°C and compo...
Embodiment 2
[0034] (1) 15 parts of PTMEG1000, 51 parts of PTMEG2000, 24.2 parts of EP330, 8.3 parts of BDO, 0.33 parts of H 2 O, 0.988 parts of AK7703, 0.16 parts of BDMAE and 0.022 parts of T-12 were mixed uniformly to obtain component A;
[0035] After mixing 50 parts of MDI, 30 parts of PTMEG1000 and 20 parts of PTMEG2000, under nitrogen protection atmosphere, stirred and reacted at 85°C for 4 hours to obtain component B with -NCO value of 13.39;
[0036] (2) According to the molar ratio of 1:1 molar ratio of active H in component A and -NCO group in component B, component A preheated to 35°C and component B preheated to 45°C were passed through two-component After the polyurethane pouring machine is mixed evenly, it is poured into a lockable mold preheated to 65°C, and the inner cavity volume is 868cm 3 Inject a mixture with a total mass of 434g into the mold, and then place the mold injected with the mixture at 65°C to cure for 10 minutes. After the mixture is expanded and molded, t...
