AI Technical Summary

Technical Problem

The existing ultralight clay crosslinking agents have toxicity problems and are difficult to form stable crosslinking polymers, which affects their viscoelastic properties and temperature resistance.

Method used

Ultralight clay crosslinking agent composed of triethanolamine, tartaric acid or citric acid, aluminum trichloride, zirconium octahydrate, acetic acid or hydrochloric acid, sodium chloride or potassium chloride are used to form a transition metal organic crosslinking agent through coordination reaction to ensure the stability and firmness of the crosslinking reaction.

Benefits of technology

It realizes a non-toxic and environmentally friendly ultralight clay crosslinking agent, which can quickly cross-link polyvinyl alcohol to form a stable gel, has excellent tensile properties and temperature resistance, and meets the rapid cross-linking and stability requirements of ultralight clay.

Abstract

The invention belongs to the field of ultralight clay, and relates to an ultralight clay cross-linking agent, ultralight clay and a preparation method thereof, the ultralight clay cross-linking agent is prepared from the following substances by weight: 9-25 parts of triethanolamine, 2-10 parts of tartaric acid or / and citric acid, 2-11 parts of aluminum trichloride, 7-25 parts of zirconium oxychloride octahydrate, 0.5-5 parts of acetic acid or hydrochloric acid, 3-10 parts of sodium chloride or potassium chloride, and 40-100 parts of deionized water. The ultra-light clay cross-linking agent, the ultra-light clay and the preparation method of the ultra-light clay have the advantages that the ultra-light clay cross-linking agent is non-toxic and environment-friendly, polyvinyl alcohol can be cross-linked and changed into gel, and the ultra-light clay meets the requirements that the ultra-light clay needs to quickly cross-link PVA and form a stable cross-linked polymer, and the viscosity is not reduced due to temperature depolymerization.
