Description
Technical field
The present invention relates to a kind of polypropylene of modification, say further, relate to polypropylene resin composite of a kind of toughening flame-proof and preparation method thereof.
Background technology
Polypropylene (PP) is the big kind plastics that have a large capacity and a wide range, and also is to be hopeful one of plastics variety of through engineering approaches in the general-purpose plastics most, and has obtained using widely in daily living article, traffic, machinery, industry such as electric.But PP very easily burns, and for security consideration, relevant department is to some Application Areass, as being used as comparatively strict fire-retardant regulation in the industries such as household electrical appliance, material of construction.In general, present stage mainly is to reduce its flame retardant resistance by add fire retardant in the PP resin matrix, delays its combustionvelocity.
Up to now, the flame retardant products overwhelming majority of domestic relevant PP is based on halide-containing, and dense smoke, toxicity and the corrosive gases that produces when fire-retardant brings serious secondary harm for production, application and environment.Therefore, the halogen-free flameproof PP of the low cigarette of exploitation, few poison is the importance in polypropylene research and development field.Wherein ammonium polyphosphate (APP) is as the halogen-free expanded flame-retardant agent, has the flame retarding efficiency height, cigarette, low toxicity, no obnoxious flavour and molten drop produce and are subjected to paying attention to widely less when being heated burning, it is a focus of present fire-retardant PP research and development, yet, in PP, add APP, can cause some physicalies of PP material, toughness variation particularly, thus limited the range of application of the fire-retardant PP of APP to a great extent.
As having provided the patent of invention for preparing a kind of flame retardant polypropylene resin composition among the Chinese patent application CN 1432045A, this invention utilizes ammonium polyphosphate and the aromatic phosphate acid ester of phenol structure is arranged as main flame retardant, tetramethylolmethane is as auxiliary flame retardant, adopt poly (phenylene ether) resin (PPE) to improve plasticity, shock resistance, thermotolerance and the uninflammability of material, but the toughness of prepared polypropylene fire retardant mixture is lower, and cantilever beam impact strength is lower.Adopt the hydrogenated block copolymer of vinyl aromatic compounds, this hydrogenated block copolymer plays a role the PPE resin aspect the homodisperse in acrylic resin, but the bending property that causes prepared material simultaneously descends obviously, its bending elastic modulus has only 1.7GPa, has limited its range of application greatly.
As U.S. Pat 6,429, provided a kind of preparation method of halogen-free flameproof blend in 246, metal-salt is adopted in this invention, metal hydrate, silicone oil and silicon rubber are as fire retardant, because used halogen-free flame retardants is mainly metal hydrate, and the flame retarding efficiency of metal hydrate is very low, need heavy addition just can reach certain flame retardant effect, even fire retardants such as adding silicon rubber carry out composite, to improve the flame retarding efficiency of metal hydrate, but required addition is also still very big, has greatly influenced the mechanical property of material, after adding polypropylene random copolymer or statistic copolymer, tensile strength descends obviously, have only 25MPa, the oxygen index of prepared fire retardant material is not high yet, in 27~31 scope.
Summary of the invention
The contriver thinks that the key that adopts inorganic combustion inhibitor filled polypropylene resin to prepare anti-flaming polypropylene material is to solve the problem of consistency between organic polymer polypropylene bodies resin and the polar inorganic combustion inhibitor.In the polymkeric substance infill system, phase interface is very crucial, and strong interfacial interaction can obtain good interface bonding and stress transmission effectively, realizes the performance optimization of material.Therefore the contriver carries out chemical modification through discovering with elastomerics, introducing by polar group makes it functionalization, can the Reinforced Polypropylene matrix resin and fire retardant APP between thermodynamic compatibility, to improve the impact property of material, in addition, the adding of grafts can also make the dispersion of fire retardant in resin matrix better, thereby produce synergistic effect with fire retardant, when improving impact property, not only do not reduce original flame retardant properties, even the generation synergistic effect, flame retarding efficiency is improved further improve flame retardant properties.
