Abstract
The invention discloses an environment-friendly flame retardant, which comprises the following raw materials in part by weight: 10 to 25 parts of expanded graphite, 20 to 35 parts of starch, 5 to 10 parts of phosphoric acid, 5 to 15 parts of melamine phosphate, 5 to 15 parts of melamine, 5 to 10 parts of urea, 5 to 10 parts of aluminium hydroxide, 5 to 8 parts of antimonous oxide, 2 to 5 parts of manganese oxide, 2 to 5 parts of nickel oxide, 2 to 5 parts of zinc oxide and 3 to 5 parts of coupling agents. According to the environment-friendly flame retardant, organic components and inorganic components are compounded for flame retarding, so that the flame retarding efficiency is high, and when the flame retardant is used for retarding flaming of polyolefin, and the minimum adding amount is 20 percent, a V-0 flame retarding level in a UL-94 testing method can be reached; the compatibility of the flame retardant and a polyolefin plastic substrate is high, so that the flame retardant can be uniformly scattered in a material to be subjected to flame retarding and has relatively high appetency; and the flame retardant has high water resistance and heat stability, so that the processing requirement of polyolefin plastic is fully met.
Description
Technical field
The invention belongs to the fire retardant technical field, be specifically related to the environment friendly flame retardant that a kind of polyolefin plastics is used.
Background technology
Polyolefine mainly refers to polyethylene and polypropylene, and wherein polyvinyl resin output ranks first in the world, and polypropylene is the minimum kind of common resins density, good combination property, and modification is wide in variety, is one of comparatively faster kind of development in the resin.Polyethylene and polypropylene are present two maximum large general-purpose plastics of most widely used, output.Along with the increasingly stringent that requires to material environment friendly, safety performance, the fire retardant polyolefin plastics become inexorable trend.
Expansion type flame retardant is the fire retardant take phosphorus, nitrogen as chief component of developing in recent years, have environmental protection, efficient, low-smoke low-toxicity, addition is low and to advantages such as the polymer machinery performance impact are less, surface energy formed one deck dense foam charcoal layer when the material that contains this based flame retardant was heated, play heat insulation, oxygen barrier, press down the cigarette effect, can prevent molten drop again, in flame-retardant polypropylene plastics, use more and more extensive.At present, phosphorus nitrogen systems halogen-free expansion fire retardant research take ammonium polyphosphate (APP) as the basis is more, although it has preferably flame retardant properties, APP has stronger water absorbability, water tolerance and poor heat stability are difficult to satisfy the processing request of polyolefin plastics.
Summary of the invention
The purpose of this invention is to provide a kind of environment friendly flame retardant, its flame retarding efficiency is high, and Heat stability is good satisfies the processing request of polyolefin plastics fully.
Technical scheme of the present invention is: a kind of environment friendly flame retardant, it is characterized in that, made by the raw material of following weight parts: expanded graphite 10-25, starch 20-35, phosphoric acid 5-10, melamine phosphate 5-15, trimeric cyanamide 5-15, urea 5-10, aluminium hydroxide 5-10, antimonous oxide 5-8, manganese oxide 2-5, nickel oxide 2-5, zinc oxide 2-5, coupling agent 3-5.
The preferred technical scheme of the present invention is: a kind of environment friendly flame retardant, it is characterized in that, made by the raw material of following weight parts: expanded graphite 15, starch 30, phosphoric acid 5, melamine phosphate 10, trimeric cyanamide 10, urea 8, aluminium hydroxide 6, antimonous oxide 5, manganese oxide 2, nickel oxide 3, zinc oxide 2, coupling agent 4.
Above-mentioned coupling agent is selected from a kind of in γ-aminopropyl triethoxysilane, N-β-aminoethyl-γ-aminopropyltrimethoxysilane, N-β-aminoethyl-γ-aminopropyl methyl dimethoxysilane or the titante coupling agent.
Preparation method: each component of fire retardant put in the high speed mixer in proportion mix, can obtain environment friendly flame retardant of the present invention.
When meeting fire, expanded graphite is expanded by heating at first, and volume can reach original more than 100 times after expanding, and forms tough and tensile charcoal layer at polymer surfaces, and polymkeric substance and thermal source are separated, and in a large number heat absorption reduces system temperature in expansion process.When polymer surfaces reaches certain temperature; under the acting in conjunction of acid source phosphoric acid and melamine phosphate and source of the gas trimeric cyanamide and urea; the carbonization of dewatering rapidly of carbon forming agent starch; form fluffy carbon-coating at protected polymer surfaces; the carbon-coating that forms with expanded graphite cuts off contacting of polymkeric substance and oxygen together, stops further spreading of fire.Metallic compound aluminium hydroxide, antimonous oxide, manganese oxide, nickel oxide, zinc oxide can play the cooperative flame retardant effect, and smoke suppressing effect is remarkable.Organic and inorganic component in the fire retardant prescription becomes as a whole by the crosslinked action of coupling agent, each component synergy, add and to have excellent fire-retardant and smoke suppressing in the polyolefin plastics, water tolerance and Heat stability is good satisfy the processing request of polyolefin plastics fully.
The beneficial effect of fire retardant of the present invention:
1, organic and inorganic compounding is fire-retardant, flame retarding efficiency is high, and when being used for fire retardant polyolefin, addition is minimum to be 20%(wt) time, can reach the V-0 flame retardant rating of UL-94 testing method, compared to existing technology, addition significantly reduces, and has reduced cost;
2, good with the consistency of polyolefin plastics matrix, can be in fire-retardant material Uniform Dispersion, and preferably avidity is arranged, do not affect polyolefinic processing characteristics and mechanical property;
3, water tolerance and Heat stability is good satisfy the processing request of polyolefin plastics fully;
4, the amount of being fuming is few, and is not halogen-containing, belongs to environment friendly flame retardant.
