Abstract

The invention discloses a preparation method for a medical stone-based composite smoke suppressor, which belongs to the technical field of functional materials. According to the preparation method, medical stone is ball-milled, screened and calcined, so that pretreated medical stone is obtained; the pretreated medical stone and organic acid are mixed, ball-milled and screened, so that a ball-milled material is obtained; the ball-milled material, ammonium molybdate and a sodium alginate solution are stirred and mixed, drying, grinding and screening are carried out, so that a ground material isobtained; the ground material and sulfuric acid are heated and stirred to react, and after filtering, drying, grinding and screening, a pretreated ground material is obtained; the pretreated ground material, a barium nitrate solution, an ammonium sulfate solution, siloxane, a surfactant, tar and plant essence are stirred and mixed, and after drying, the medical stone-based composite smoke suppressor is obtained. The medical stone-based composite smoke suppressor provided by the invention has an excellent smoke suppression effect.

Description

technical field [0001] The invention discloses a preparation method of a medical stone-based composite smoke suppressant, which belongs to the technical field of functional materials. Background technique [0002] With the extensive application of polymer materials, the problem of combustion and smoke is becoming more and more prominent. 80% of the deaths in fires are caused by the smoke from the combustion of polymer materials and the suffocation of toxic gases. The smoke reduces the visibility of the fire scene and delays the opportunity to extinguish the fire and save lives and properties. Therefore, the study of the smoke generation of polymer materials and the development of high-efficiency smoke suppressants have become important topics in the field of material research in recent years. A large number of studies have shown that molybdenum compounds are compounds with excellent smoke suppression properties. Ammonium molybdate and molybdenum trioxide are high-efficiency...
