Modified high-sulfur-corrosion-resistance agent and preparation method thereof

The invention discloses a preparation method of a modified high-sulfur-corrosion-resistance agent, which comprises the following steps: 1) uniformly dispersing sodium citrate, sodium benzoate and a silicone oil hydrophobic material in water, and heating and swelling the obtained mixed solution under a protective atmosphere; then raising the temperature to 55-60 DEG C, adding ethylene bis-stearamide, and carrying out heat preservation treatment, so as to obtain a sulfur corrosion resistant component; and 2) mixing the obtained sulfur corrosion resistant component with a Kijiang aqueous solution, adding lithium hydroxide, and stirring the mixture at 45-60 DEG C to obtain the modified high sulfur corrosion resistant agent. The modified high-sulfur-corrosion-resistance agent can effectively reduce generation of calcium sulfate and ettringite, can participate in a hydration reaction, improves the compactness of concrete, and promotes stable development of strength. 本发明公开了一种改性高抗硫腐蚀剂的制备方法，其制备方法包括如下步骤：1)将柠檬酸钠、苯甲酸钠、硅油
