Abstract

The invention relates to a palygorskite clay based multifunctional assistant of macromolecular materials and a preparation method for the palygorskite clay based multifunctional assistant. The methodcomprises the steps: crushing palygorskite clay, adding a couplant, carrying out stirring treatment at normal temperature so as to obtain surface modified palygorskite clay, carrying out drying, and re-crushing the palygorskite clay; then, dispersing the surface modified palygorskite clay into ethyl acetate, sequentially adding a compound 1-propylphosphoric anhydride and a compound 5-aminotetrazole, carrying out ultrasonic treatment, and then, carrying out stirring for a period of time; and finally, carrying out air flow drying, recovering the ethyl acetate solvent, and grinding a dried powderproduct, thereby obtaining the palygorskite clay based multifunctional macromolecular assistant. Shown by experiments, the palygorskite clay based multifunctional assistant prepared by the method hasexcellent comprehensive properties, the thermal stability, cross-linking degree, flame retardance, tensile strength and impact strength of the materials can be comprehensively improved, and the smokedensity and combustion toxicity can be lowered, so that the multifunctional assistant of the macromolecular materials is relatively ideal and has very good prospects in the field modification of macromolecular composite materials.

Description

technical field [0001] The invention relates to a polymer material additive, in particular to a palygorskite clay-based polymer material additive and a preparation method thereof, belonging to the technical field of composite functional materials. Background technique [0002] Polymer synthetic materials, such as polypropylene, polyethylene, polystyrene, nylon, rubber, etc., have been widely used in various industries. However, each industry has different needs for polymer materials, which also determines that a polymer synthetic material cannot be omnipotent, and it needs to be adjusted according to the special requirements such as the material and performance of the product during the application process. [0003] Chemical additives for polymer materials refer to various auxiliary materials added to the polymer system of the target material in order to improve the processing performance of polymer materials such as plastics and rubber, improve the physical and mechanical p...
