Abstract

The invention discloses a polymer material containing microencapsulated rare earth metal hypophosphite, and a preparation method thereof. According to the percentages in the total mass of the composite material, 30-90% of a polymer material, 5-15% of microencapsulated rare earth metal hypophosphite, 5-10% of a nitrogen-series flame retardant, 0-30% of an enhancing agent, 0-6% of a char-forming agent, 0-2.5% of a nano-grade synergist, 0-5% of a compatibilizing agent, 0-1% of a lubricant, and 0-0.5% of an antioxidant are well mixed; the mixture is heated to a temperature of 120-265 DEG C; melt blending, extrusion, drawing, cooling, pelletizing and bake-drying are carried out, such that the polymer material provided by the invention is obtained. The polymer material provided by the invention has good flame retardant property, good mechanical performances, good water precipitation resistance and good weather resistance. With the preparation method, defects of high halogen flame retardant environmental hazard, high inorganic flame retardant addition amount, poor thermal stability, poor water resistance and the like of traditional polymer flame-retardant modification technologies are overcome. The method and the material have good application prospect.

Description

technical field [0001] The invention relates to the technical field of halogen-free flame retardancy and plastic processing application, in particular to a polymer material containing microencapsulated rare earth metal hypophosphite and a preparation method thereof. Background technique [0002] Compared with traditional materials such as cement, glass, ceramics and steel, polymer materials are latecomers, but their development speed and wide range of applications have greatly surpassed traditional materials. In recent years, polymer materials are no longer substitutes for traditional materials, but have become important materials in the fields of industry, agriculture, national defense and science and technology. Polymer materials are ubiquitous, widely permeated in all aspects of human life, and play a huge role in people's lives. However, polymer materials generally have the disadvantages of being flammable, easy to drip after burning, and producing a lot of toxic fumes....
