Description

Low-smoke non-halogen flame-retardant ethene-vinyl acetate copolymer resins
Technical field
The invention belongs to macromolecular material, particularly a kind of low-smoke non-halogen flame-retardant ethene-vinyl acetate copolymer resins.
Background technology
Ethene-vinyl acetate copolymer resins (hereinafter to be referred as EVA) is that one is widely used in the industries such as fireproof blocking, electric wire, auto parts machinery, electronic apparatus, toy.Conventionally EVA resin belongs to inflammable material, and oxygen index is lower, and the amount of being fuming is larger in combustion processes, and neat coal amout is very high, is very necessary so EVA resin is carried out to fire-retardant research.At present fire-retardant synthetic resins is fewer, therefore multiselect flame retardant rubber product.The flame retardant rubber product that market is common, because the prices of raw and semifnished materials are higher, so production cost is high, and complex manufacturing.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of environmental protection, flame retardant properties good, the low-smoke non-halogen flame-retardant ethene-vinyl acetate rubber that production cost is low.
The technical scheme that technical solution problem of the present invention adopts is: a kind of low-smoke non-halogen flame-retardant ethene-vinyl acetate copolymer resins, it is characterized in that by ethene-vinyl acetate rubber, Halogen meet flame-retardant system, processing aid is made; Described Halogen composite flame retardant system is made up of inorganic hydroxide; Described processing aid is made up of talcum powder, titanium dioxide, carbon black, linking agent.The weight part of each component is as follows: 100 parts of ethene-vinyl acetate rubber, inorganic hydrogen aluminum oxide or inorganic hydrogen magnesium oxide 110-130 part, talcum powder 15-25 part, titanium dioxide 1.5-2.0 part, carbon black 1.0-1.5 part, linking agent 3.0-3.5 part.
Described ethene-vinyl acetate copolymer resins EVA content is 40%-80%.
Described Halogen composite flame retardant system is aluminium hydroxide or magnesium hydroxide by inorganic hydroxide, and order number contains 2000 at 2000() more than order.
Described linking agent is TBPB.
The invention has the beneficial effects as follows: low-smoke non-halogen flame-retardant ethene-vinyl acetate copolymer resins of the present invention environmental protection, flame retardant properties are good, its oxygen index (O.I) > 40%, maximum smoke density (MSD) < 45, smoke density grade (SDR) < 20; Compound IMO is A.754(18) requirement of A-60 level, meet GB23864, GJB4000-2000 and GJB150-86 standard; Starting material source is sufficient, and cost is low.

Embodiment 1, a kind of low-smoke non-halogen flame-retardant ethene-vinyl acetate copolymer resins, is made up of the component of following weight parts: 100 parts of ethene-vinyl acetate rubber, 130 parts, inorganic hydrogen aluminum oxide or inorganic hydrogen magnesium oxide, 25 parts of talcum powder, 2.0 parts of titanium dioxides, 1.5 parts of carbon blacks, 3.5 parts of linking agents.Wherein inorganic hydrogen aluminum oxide or inorganic hydrogen magnesium oxide are Halogen composite flame retardant system.Talcum powder, titanium dioxide, carbon black, linking agent are processing aid.
Described Halogen composite flame retardant system is aluminium hydroxide by inorganic hydroxide, or magnesium hydroxide, and order number contains 2000 at 2000() more than order.
Described linking agent is TBPB.
Described talcum powder be white or off-white color, fine, without the powder of grittiness, hand touches with greasy feeling.Odorless, tasteless.It does not all dissolve in water, dilute sulphuric acid or alkali hydroxide solution.
Described titanium dioxide formal name used at school is titanium dioxide, belongs to inertia fuel, is considered at present the best a kind of white pigment of performance in the world.It both as tinting material, has again reinforcement, anti-aging, filling effect in rubber industry.
The fine particle that described carbon black forms after for incomplete combustions such as coal, oil, biomass fuels.In copolymer resins processing, by making strengthening agent and filler in copolymer resins mixing adding.
The preparation method of this low-smoke non-halogen flame-retardant ethene-vinyl acetate copolymer resins, adopt the method for doubling stove routine: after 100 parts of ethene-vinyl acetate rubber are plasticated fully, cooling after adding inorganic hydrogen aluminum oxide or inorganic hydrogen magnesium oxide, talcum powder, titanium dioxide, carbon black, linking agent banburying fully at 80 DEG C-90 DEG C; Cold-draw vacuum 15-20 minute, is warming up to 70 DEG C and starts constant temperature and vacuumize 15-20 minute, in the time that colloid does not also melt completely, takes out air again, forms bubble in order to avoid air is enclosed in glass; Doubling stove slice.
