Abstract
A polymer-based composite flame-retarding material contains proportionally the low-temp expansible graphite and the polymer which may be the copolymer of polyethene, polypropene, polystyrene and styrene.
Description
One, technical field
The present invention relates to a kind of polymer matrix composite, particularly relate to a kind of polymer-base flame-proof composite material.
Two, background technology
Polymer-base flame-proof composite material is the important focus of polymer modification.The fire retardant that uses has bromide fire retardant, nitrogen flame retardant, organic phosphorus flame retardant, inorganic phosphorus flame retardant, expansion type flame retardant etc.
Expansible black lead is subjected to high heat effect, and the high power expansion can take place rapidly, as expands 200～300 times, can be used as expansion type flame retardant.But in fact, in the past discover that expansible black lead is not good fire retardant, such as being used for polyacrylic composite flame-proof, though the quality consumption of expansible black lead to 30% o'clock flame retardant effect and bad, oxygen index only about 22.
Three, summary of the invention
The object of the present invention is to provide the polymer-base flame-proof composite material that a kind of expansible black lead consumption is few, flame retardant properties is excellent, product cost is low.
The technical scheme that realizes the object of the invention is: a kind of polymer-base flame-proof composite material, comprise polymkeric substance and expansible black lead, wherein expansible black lead is the expandable graphite at low-temperature of allowance for expansion more than 200mL/g when 280 ℃ of swelling temperatures, and polymkeric substance is that fusing point is lower than 200 ℃ polymkeric substance.
In the polymer-base flame-proof composite material of the present invention, polymkeric substance is polyethylene, polypropylene, polystyrene and styrol copolymer.
In the polymer-base flame-proof composite material of the present invention, the massfraction of expansible black lead is 10%～35%.
Compared with prior art, the present invention has remarkable advantage.The present invention finds to use when 280 ℃ of swelling temperatures the expandable graphite at low-temperature of allowance for expansion more than 200mL/g as fire retardant, and be used for the fire-retardant compound of polymkeric substance such as polyethylene, polypropylene, polystyrene and styrol copolymer that fusing point is lower than 200 ℃, the flame-proof composite material that obtains has excellent flame-retardant, and the consumption of expansible black lead is few and the flame-proof composite material product cost is low.
