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 technical field of flame retardant, be specifically related to a kind of environment friendly flame retardant of polyolefin plastics.
Background technology
Polyolefine mainly refers to polyethylene and polypropylene, and wherein polyvinyl resin output ranks first in the world, and polypropylene is the kind that common resins density is minimum, good combination property, and transformed lines show is many, is develop one of comparatively faster kind in resin.Polyethylene and polypropylene are the two large general-purpose plastics that most widely used, output is maximum at present.Along with the requirement increasingly stringent to material environment friendly, safety performance, fire retardant polyolefin plastics become inexorable trend.
Expansion type flame retardant is that what to develop in recent years take phosphorus, nitrogen as the fire retardant of main composition, there is environmental protection, efficient, low-smoke low-toxicity, addition are low and to advantages such as polymer machinery performance impact are less, when material containing this based flame retardant is heated, surface energy forms one deck dense foam layer of charcoal, play heat insulation, oxygen barrier, press down cigarette effect, can molten drop be prevented again, apply more and more extensive in flame-retardant polypropylene plastics.At present, phosphorus nitrogen systems halogen-free expansion fire retardant research based on ammonium polyphosphate (APP) is more, although it has good flame retardant properties, APP has stronger water absorbability, water tolerance and poor heat stability, be difficult to the processing request meeting polyolefin plastics.
Summary of the invention
The object of this invention is to provide a kind of environment friendly flame retardant, its flame retarding efficiency is high, Heat stability is good, meets the processing request of polyolefin plastics completely.
Technical scheme of the present invention is: a kind of environment friendly flame retardant, it is characterized in that, be made up of 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, be made up of 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 the one in γ-aminopropyl triethoxysilane, N-β-aminoethyl-γ-aminopropyltrimethoxysilane, N-β-aminoethyl-γ-aminopropyltriethoxy dimethoxysilane or titante coupling agent.
Preparation method: each for fire retardant component is put in high speed mixer in proportion and mixes, environment friendly flame retardant of the present invention can be obtained.
When meeting fire, expanded graphite is expanded by heating first, and after expanding, volume can reach original more than 100 times, forms tough and tensile layer of charcoal, polymkeric substance and thermal source are separated, absorb heat in a large number in expansion process at polymer surfaces, reduces system temperature.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 carbon forming agent starch rapid dehydration; fluffy carbon-coating is formed at protected polymer surfaces; cut off contacting of polymkeric substance and oxygen together with the carbon-coating that expanded graphite is formed, stop spreading further of fire.Metallic compound aluminium hydroxide, antimonous oxide, manganese oxide, nickel oxide, zinc oxide can play cooperative flame retardant effect, and smoke suppressing effect is remarkable.Organic and inorganic component in flame retardant formulations becomes as a whole by the crosslinked action of coupling agent, each component synergy, add in polyolefin plastics and have excellent fire-retardant and smoke suppressing, water tolerance and Heat stability is good, meet the processing request of polyolefin plastics completely.
The beneficial effect of fire retardant of the present invention:
1, organic and inorganic compounding is fire-retardant, flame retarding efficiency is high, and during for fire retardant polyolefin, addition is minimum is 20%(wt) time, can reach the V-0 flame retardant rating of UL-94 testing method, compared to existing technology, addition significantly reduces, and reduces cost;
2, good with the consistency of polyolefinic plastic substrate, can be dispersed in fire-retardant material, and have good avidity, do not affect polyolefinic processing characteristics and mechanical property;
3, water tolerance and Heat stability is good, meets the processing request of polyolefin plastics completely;
4, the amount of being fuming is few, not halogen-containing, belongs to environment friendly flame retardant.
