At present, the most important requirements for the bonding agent of the refractory material are that a new low-melting phase is generated little or not at high temperature, the purity of the material is improved, the bonding agent is adapted to the high-temperature service performance of the material, and the high-temperature sintering strength, the erosion resistance, the slag penetration resistance and the like of the material are improved. The colloidal binder belongs to a hot binder system at the present stage, and the colloidal binder enables the binding of the binder and the material to be more stable and the integrity to be stronger when the colloidal binder loses water. The method avoids the adverse effects caused by low-melting-point substances such as melilite and the like generated by CaO brought by calcium aluminate cement, and improves the high-temperature performance of the material. The construction solidification and hardening time of the colloidal binder is controllable, and the chemical components of the colloidal binder are basically consistent with the main components of the material, so that the colloidal binder has small influence on the high-temperature performance of the material and basically negligible influence on the environment, and can be used as an ideal binder. High-aluminum polymer is a new sol system, and is a hot spot of attention and research. However, because of the influence of technology, reaction conditions and the like, the cost of synthesizing and assembling the high-aluminum polymer is too high, the product separation is difficult, the impurity content is high, and a simple and systematic technical scheme is lacked.
The patent (CN 108676172A) discloses a method for synthesizing multidentate coordination polymer by a liquid phase method, wherein the prepared polymer shows strong acidity or alkalinity when meeting water, and is easy to participate in reaction when being applied to refractory materials, so that the swelling and hardening problems of the materials are caused, and the strength of the materials is reduced. In order to make the bonding performance of the material better, a neutral polymer is developed and has good application prospect.
