Abstract

The invention relates to the technical field of high-molecular materials, in particular to a flame-retardant high-molecular material and a preparation method thereof. The preparation method includes:sequentially adding polyvinyl chloride, nano calcium silicate hydrate, calcium sulfate, pyridine-styrene-butadiene latex, polyvinylidene chloride, antimonous oxide, alumina hydroate, zinc borate, magnesium hydroxide, polybenzimidazole fiber, DOPO derivative flame retardant, modified inorganic filler, compatilizer, toughener, plasticizer and defoamer into a multidirectional motion mixing stirrer, mixing and stirring for 15-20min, and stirring while hot melting for 0.8-1h; 2), subjecting a high-molecular material after stirring to double-screw extrusion, wherein length-diameter ratio of a double-screw extruder is 50:1, extrusion temperature at the first stage is 60-80 DEG C, the extrusion temperature at the second stage is 100-120 DEG C, and the extrusion temperature at the third stage is 140-160 DEG C; 3), pelletizing the high-molecular material after double-screw extrusion to obtain the flame-retardant high-molecular material. The flame-retardant high-molecular material is simple in preparation process, low in cost and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame-retardant polymer material and a preparation method thereof. Background technique [0002] Polymer materials, also known as polymer materials, are materials based on polymer compounds. One is that the molecular weight is large (generally above 10,000), and the other is that the molecular weight distribution has polydispersity. That is, high molecular compounds are different from small molecules. After the polymerization process, they become a mixture of many high polymers with different molecular weights; most high molecular materials, except for the basic component polymers, in order to obtain various practical properties Or improve its molding performance, generally there are various additives. The composition of the material and the ratio between the components fundamentally guarantee the performance of the product, while various additives optimize the perf...
