[0028] The preparation method of temperature control additive is:
[0029] (1) Take N-[3-(triethoxysilyl)propyl]-4,5-dihydroimidazole according to the mass ratio of 2~5:3~7, add hexadecane bromide and mix, and heat up to 70~80 ℃, pass nitrogen protection, stir and mix for 2~4 days, filter, take the filtrate, add acetone according to the mass ratio of 2~5:10~15, stir and mix at 50~60℃ for 30~60min, cool to room temperature, filter, take the filtrate a. Take SBA-15 molecular sieve and dry it at 90-100°C for 18-24 hours to obtain a dried product;
[0030] (2) Take the dry matter and add toluene at a mass ratio of 2~5:10~20, pass through nitrogen protection, heat up to 100~110°C, stir and mix for 30~50min, then add filtrate a that is 3~6 times the amount of dry matter, and stir Mix for 18~24 hours, filter, take the filter cake and dry to obtain the dried product a, take the dried product a according to the mass ratio of 1~5:10~15, add absolute ethanol, extract by Soxhlet for 24~4...
