Description
Technical Field
The invention relates to the technical field of high polymer materials, in particular to a heat-resistant flame-retardant polypropylene composition and a preparation method thereof.
Background
Polypropylene is one of the most widely used general plastics due to its excellent comprehensive properties, good cost performance and wider processing and forming conditions. The polypropylene is a typical flammable material, the limiting oxygen index of the polypropylene is 17-18%, the polypropylene is extremely easy to burn and cannot be self-extinguished after being ignited, and the polypropylene material needs to be subjected to flame retardant modification along with the gradual increase of the safety requirement of the material.
The flame retardant for polypropylene is mainly divided into bromine-antimony flame retardant and halogen-free flame retardant, and in the existing flame-retardant modified polypropylene material, in order to meet the requirement of non-halogenation, a flame retardant containing phosphorus and nitrogen or a compound system of the phosphorus and nitrogen is required to be added. At present, the most common phosphorus-containing flame retardants and compositions thereof mainly comprise phosphate esters, intumescent flame retardant systems mainly comprising ammonium polyphosphate and the like. However, compared with the traditional bromine-antimony compound flame retardant system, the flame retardant system has the defects of low flame retardant efficiency, easy precipitation and the like, needs to be added by more than 30 percent, and has great limitation in wide application. The bromine flame retardant has no flame retardant effect, so the bromine flame retardant is required to be compounded with an antimony-containing compound for use, the bromine-antimony flame retardant has the advantages of higher flame retardant efficiency, smaller influence on physical properties and the like, the using amount of the bromine-antimony flame retardant reaches the V0 (2.0 mm) grade of UL-94 by 30 percent, but the bromine-antimony flame retardant also has the defects of high smoke density, poor heat resistance, easy precipitation and the like during combustion.
With the increasing demand of downstream industry applications, more and more products and safety regulations are expected to achieve V-0 flame retardant rating and minimum smoke emission, and antimony used as a rare element for flame retardant brings about reduction of mineral resources, and is limited to be used in part of the regulations (such as the U.S. California No. 65 act).

From the example 4 and the comparative example 1, it can be seen that when the flame retardant synergist compounded by the inorganic powder filler and the zinc-containing inorganic compound is not added, the flame retardant effect is poor, the smoke density is high, and the heat resistance and the precipitation resistance are greatly reduced; as can be seen from the comparative example 2, the combination of the brominated flame retardant, the inorganic powder filler and the flame-retardant synergist compounded by the zinc-containing inorganic compound has poor flame-retardant effect, high smoke density grade and poor heat resistance; as can be seen from the comparative example 3, the flame retardant effect is poor when the phosphorus flame retardant, the inorganic powder filler and the zinc-containing inorganic compound are singly matched with the flame retardant synergist; as can be seen from the example 4 and the comparative example 4, the compound system of the brominated flame retardant, the phosphorus flame retardant and the antimony trioxide has poor flame retardant effect, high smoke density and poor precipitation resistance and heat resistance; as can be seen from comparative example 5, the bromine-antimony compound flame retardant has poor flame retardant effect, high smoke density, poor heat resistance and poor precipitation resistance under the addition amount; as can be seen from comparative example 6, the use of the halogen-free flame retardant, although good in flame retardancy and low in smoke density grade, is inferior in heat resistance and precipitation resistance.
