Embodiment 1
[0022] Embodiment 1: Preparation of multifunctional composite surface environment restoration agent
[0023] First weigh 43 kg of raw materials polyvinyl alcohol, 38 kg of starch, 6 kg of acrylic acid, and 1.2 kg of acrylamide.
[0024] Utilize above-mentioned raw material to prepare the concrete process of multifunctional compound surface environment remediation agent as follows:
[0025] (1) First add 141 kg of water into the low-temperature reaction kettle, then add polyvinyl alcohol, and stir at a temperature of about 130°C for 25 minutes;
[0026] (2) Add modified starch and stir;
[0027] (3) Add acrylic acid and acrylamide to a concentration of 10% respectively with water, then drop them into the reaction kettle, and stir while adding the mixture. During the dropwise addition, the temperature of the reaction kettle is controlled at 110-120° C., and the stirring time is 40-80 minutes;
[0028] (4) Pour out the reacted liquid from the reaction kettle and store it as a l...
