Abstract
The invention discloses flame-retardant polypropylene modified plastic. The flame-retardant polypropylene modified plastic comprises the following components in parts by weight: 100-120 parts of polypropylene, 1-10 parts of calcium carbonate, 0.8-3 parts of glyceryl monostearate, 1-3 parts of tributoxy ethyl phosphate, 1-2 parts of nano aluminium hydroxide, 1-5 parts of nano magnesium hydroxide and 0.1-0.8 part of polyethylene glycol. The flame-retardant polypropylene modified plastic prepared in the invention has the characteristics of low additive amount of a flame retardant, good flame retardant effect, high stability and good dispersion.
Description
Technical field
The invention belongs to modified plastics technical field, be specifically related to a kind of polypropylene flame redardant modified plastics.
Background technology
In recent decades, the polymer materialss such as plastics, rubber, synthon and goods thereof obtain vigorous growth, they replace traditional steel, metal, cement and the natural polymer such as timber, cotton just rapidly, are widely used in each department of the national economy such as industry, agricultural, military affairs.They improve the life of people, by people are necessary.Namely the turnout of plastics in 2000 reaches 1.7 hundred million tons, and its volume substantially exceeds produces steel volume the same year.But most of superpolymer belongs to inflammable, combustible matl, when burning, heat release rate is large, and calorific value is high, flame propagation speed, not easily extinguishes, and sometimes also produces thick smoke and toxic gas, works the mischief to environment, form huge threat to the life security of people.Therefore, the flame retardant resistance how improving synthetic high polymer and natural high polymer material has become a urgent problem.
The fire-retardant of material realizes mainly through following approach: 1, gas phase fire retardant mechanism, namely suppresses the free radical playing chain propagation in combustion reactions, and plays fire retardation; 2, condensed phase fire retardant mechanism, namely stops the thermolysis of polymkeric substance and stops polymkeric substance to discharge the effect of inflammable gas in solid phase; 3, interrupt heat exchange mechanism, the heat by polymkeric substance generation is taken away and is not fed back on polymkeric substance, and polymkeric substance is no longer constantly decomposed.
