By means of the halogen-free flame-retardant polyolefin material for the plastic woven product, the glass fibers are a strengthening framework, and filled with a halogen-free flame retardant, and under the condition of guaranteeing the high flame retarding performance of the polyolefin material, good strength is kept.
Description
Technical field
The invention belongs to plastic working and modification field, being specifically related to a kind of for moulding the halogen-free anti-flaming polyolefin material and complete processing of compiling product.
Background technology
At present, China's plastic knitting industry is in the stage of slim profit and cut-throat competition, must accelerate innovation shape compile series product to obtain more high profit Su Bian enterprise, as: have that low-smoke non-halogen flame-retardant, anti-electrostatic etc. are functional moulds volume novel material; Traditional polyolefin plastics woven bag superpolymer belongs to inflammable, combustible matl, when burning, Thermal release speed is large, calorific value is high, flame propagation speed, not easily from putting out, flame-retarding power is strong, also can produce thick smoke or poisonous, harmful, mordant gas when burning, causing the harm of Secondary disaster to environment and the lives and properties to people to bring huge threat; This kind of woven bag material very easily causes burning when meeting fire, and intensity not good enough event use range is restricted.
The fire retardant of polyolefin modified material is generally divided into response type and addition type two class.The reactive flame retardant group that mainly introducing has a fire retardation on the main chain or side chain of superpolymer in polymerization and polycondensation process is to reach fire-retardant object.It has good stability, not easily disappear, toxicity is little, on advantages such as superpolymer performance impact are little, but synthesis and complete processing complexity.Therefore in actual production process, mainly apply additive flame retardant, polyolefin modified material adopts halogenated flame retardant flame-retardant modified to carry out always for a long time, such as decabromodiphynly oxide, brominated epoxy resin, bromination alkane etc.Although halogenated flame retardant has good flame retardant resistance, a large amount of smog can be discharged out when burning, produce toxic gas, and the gases such as the hydrogen halide discharged out having corrodibility, make lives and properties suffer heavy losses.
Present various countries have limited the use of halogenated flame retardant all, then adopt the phosphorus system of environmental protection more, nitrogen system, silicon system and inorganic combustion inhibitor to carry out flame-retardant modified.Domestic also to develop phosphorus system, phosphorus-nitrogen system, phosphorus-silicon system flame-retardant system, and form scale, but common phosphorus-nitrogenated flame retardant is the tri compound fire retardant of poly phosphate, tetramethylolmethane and trimeric cyanamide, when addition is greater than 30%, the effect of V-0 level just can be reached.Inorganic combustion inhibitor is as just having flame retardant effect when the inorganic combustion inhibitors such as red phosphorus, magnesium hydroxide, aluminium hydroxide need addition more than 50%, and flame retarding efficiency is lower.And it is larger to add the Effect on Mechanical Properties of a large amount of fire retardants to polyolefin modified material.
Patent publication No. is the application for a patent for invention of CN1566195A, disclose a kind of non-halogen flameproof polypropylene materials, it is made up of by weight following component: homo-polypropylene powder-granule material 40-80, ammonium polyphosphate 2-50, melamine phosphoric acid salt 10-40, tetramethylolmethane 1-10, dripping inhibitor 0.1-2, oxidation inhibitor 0.1-0.3, coupling agent 0.1-0.3, fundamentally overcome the anti-flaming polypropylene material of Halogen resistance element to the pollution of environment and shortcoming human body being had to harm, play the safety effect both ensureing fire protection flame retarding, again can in the unexpected fire occurred, the gas that discharges is made to be reduced to minimum level to the harm of human body and environment and pollution.
Patent publication No. is the patent application of CN104844929A, disclose a kind of halogen-free flame retardant polypropylene composite material of one, add the nano combined additive of polynite/polypropylene polymerization of 5 ~ 15wt% as polypropylene halogen-free flameproof synergist and the firm toughner of increasing, polynite/polypropylene polymerization nano material graft modified polypropene and nano imvite, as base material, add that octadecyl trimethyl ammonium chloride obtains as intercalation modifying agent.Polypropylene material of the present invention do not adopt/and the nano combined additive of polypropylene polymerization is as halogen-free flameproof synergist and increase firm toughner, thus avoid halogen-free flame retardants to be hydrolyzed problem, while synergy is fire-retardant, improve mechanical property and the resistance toheat of matrix material.
Publication number is the patent application patent of CN103435903A, and it uses a kind of Low-smoke zero-halogen flame-retardant polyolefin thermoplastic elastomer and preparation method thereof.Specifically, polyolefin elastic particle manufacturing soft mobile low-smoke halogen-free combustion-preventing cable insulation layer or restrictive coating and preparation method thereof is used to.Described Low-smoke zero-halogen flame-retardant polyolefin thermoplastic elastomer is with ethylene-octene copolymer, terpolymer EP rubber, ethylene-vinyl acetate copolymer resins, aluminium hydroxide, magnesium hydroxide, Magnesium Stearate, oxidation inhibitor, polyethylene wax, linking agent, vulcanizing agent
Deng raw material, after mixing, extrude with six temperature section twin screw extruders and form.Adopt the present invention to make electric wire, complete processing is simple, has the features such as low-smoke non-halogen flame-retardant, softness, good springiness, wear resistance are good.Summary of the invention
The technical problem to be solved in the present invention is the defect that will overcome conventional flame retardant, prepares halogen-free anti-flaming polyolefin material and uses this material to manufacture woven bag, for woven bag market provides wide application space.
The technical solution adopted for the present invention to solve the technical problems is:
This for moulding the halogen-free anti-flaming polyolefin material compiling product, it forms resin matrix, halogen-free flame-retardant system, antioxidant system, toughen and intensify system by four large systems.
Resin matrix used be PP or PE, PP-g-MAH:80 part, 20 parts;
Halogen-free flame-retardant system used is composite nitrogen phosphorus halogen-free flame retardants: 20-40 part;
Toughening reinforcement is POE, glass fibre (GF): 20 parts, 25 parts;
Antioxidant system used is antioxidant 1010: 0.5 part.
Preferably, phosphorus content >=22% in described composite nitrogen phosphorus halogen-free flame retardants, nitrogen content >=20%.
Before extruding pelletization experiment each time, by the forced air drying 5 hours at 100 DEG C of PP or PE material, this drying is that material is tiled to inside the special pallet of drying, and material thickness at about 2cm or below, tiles substantially even.PP-g-MAH was 55 DEG C of vacuum-dryings more than 12 hours.
Described glass fibre heats dewaxing in retort furnace, adds in water-ethanol mixed solution and floods 2 hours, then clean, put into 80 degrees Celsius of oven for drying 3 hours with the silane coupling agent of massfraction 1%.
PP, PP-g-MAH, TAF lubricant, POE, antioxidant 1010, composite nitrogen phosphorus halogen-free flame retardants are added high-speed mixer according to a certain ratio and mix 10 minutes, put into 80 DEG C of oven for drying 1 hour, add forcing machine to extrude, extrude simultaneously, the glass fibre of certain proportioning is added from venting hole, extrude, pelletizing.
Beneficial effect of the present invention is, by adding composite nitrogen phosphorus halogen-free flame retardants, greatly can improve the flame retardant properties of polyolefine material, and by adding POE and glass fibre, namely ensure that the intensity of PBT in turn ensure that toughness does not reduce.
