[0020] The embodiment of the present invention also provides a preparation method of a salt-tolerant organic boron chromium cross-linking agent, comprising: stirring and mixing the above-mentioned cross-linking agent raw materials, the method is simple and easy, and is suitable for industrial applications. The above-mentioned cross-linking agent raw materials include borax 10-40 parts, glycerin 5-30 parts, polyhydroxy compound 5-15 parts, chromium-containing compound 1-10 parts and water 5-80 parts.
[0021] Preferably, the temperature during the mixing of the crosslinking agent raw materials is 70-90° C., and the stirring is carried out for 2-4 hours. In the preparation process of the cross-linking agent, the mixing process of each raw material is controlled at about 80°C, and the reaction time is controlled at about 3 hours, which can achieve a good complexing effect and obtain a uniform cross-linking agent product. If the temperature is too high, it is easy to cause side re...
