Abstract
A fire-retarding refractory nano fibre is prepared through preparing nano additive from SiO2 and Al2O3, mixing it with cellulose, preparing spinning dope, and spinning. Its advantages are high strength and elongation, low moisture regain, and high refractory effect (1300 deg.C).
Description
Technical field:
The present invention relates to a kind of production method of fire resistance fibre, especially a kind of production method of nanometer heat-resistance and flame-retardant fiber.
Background technology:
The application of heat-resistant fireproof textile material is very widely, as aircraft, steamer, train, automobile, etc. the inner decoration material of transport facility, large-scale office building, auditoriums, hotels etc., Special Work personnel's such as fire-fighting protective clothing, the overcanopy material that occasion such as communications and transportation and construction site is used, employed heat-resistant fireproof filtering materials of various occasions such as steel mill or steam power plant or the like.The heat-resistant fireproof textile material is mainly realized by following two kinds of approach: a kind of is that textile material is carried out fire-retardant post processing, and this method cost is low, but anti-flammability can reduce along with the increase of service life and washing times or disappear gradually; Another method then is directly to produce the fire resistance fibre with permanent fire retardant, produces the more stable heat-resistant fireproof textile material of fire resistance, and this also is the method that generally adopts at present.Up to the present, existing tens kinds of heat-resistance and flame-retardant fibers on the domestic and international market, more common have an aromatic polyamide fibre (Nomex), poly-benzimidazole fiber (PBI), polyhenylene ether ketone fiber (PEEK), modification is from putting out polypropylene cyanogen fiber (PANOF), phenolic fibre, melamine fiber, ceramic fibre, polyvinyl chloride alcohol fiber, silicate fiber and glass fibre etc., although of a great variety, its production method major part all is to adopt the inertia fire retardant or utilize cyaniding acid, hydrochloric acid, bromine, zinc and the product that contains toxic side effects such as phosphate mixture and other halogen carry out flame treatment.Because existing fire retardant can't carry out flame treatment to relatively advocating the cellulose fibre that uses at present, causes the problem of present employed fire resistance fibre various degrees.As the employed heat-resistance and flame-retardant fiber of present China is glass fibre basically, and it is little to exist percentage elongation, and pliability is relatively poor, and than great, rebound performance is bad, and thermal conductivity is low, and back difficulty of processing is big, in the use human body is had shortcomings such as spread effect.Secondly employed is the aromatic series fiber, although the aromatic series fiber is a kind of more satisfactory heat-resistance and flame-retardant fiber, the height of its cost makes most of user be difficult to accept.Also having a kind of is carbon fiber, though its heat-proof combustion-resistant performance is also relatively good, also exist the high problem of cost, and its range of application also has significant limitation.
Summary of the invention:
The present invention is in order to solve technical problems such as existing in prior technology cost height, toxic side effect, the production method of the nanometer heat-resistance and flame-retardant fiber that a kind of cost is low, the heat-resistant fireproof performance is good, environment friendly and pollution-free, have wide range of applications to be provided.
Technical solution of the present invention is: a kind of production method of nanometer heat-resistance and flame-retardant fiber comprises the steps: in order
A. silica, alundum (Al are made nanometer additive respectively;
B. nanometer additive and cellulose are mixed, make spinning solution;
C. spinning.
Described silica, alundum (Al are made nanometer additive respectively for to prepare nanometer additive with the gas phase plasma processing method.
The percentage by weight of its nanometer additive is preferably 20～30%, uses static mixer, adopts the method for melt blending to prepare spinning solution.
The present invention compared with prior art difference of its maximum is with the inertia fire retardant---silica, alundum (Al are made nanometer additive respectively, make spinning solution and carry out spinning with the cellulose hybrid reaction.Fire resistance fibre by the present invention's production, can be formed with nano combined molecules of salt network and a large amount of chemical molecular water in its macromolecular inside, free nano combined salinity subchain is survived in cellulosic inside, in the fiber dewatering strengthening process, the energy of water evaporation discharges and can produce a kind of inert diluent, thereby volatilization that can the controlling fiber element forms speed.Nano combined salt combines with water and makes cellulosic combustibility that variation take place, and especially nanoparticle has changed the complex salt surface characteristic, and the surface of inorganic part helps bound atom group in the process of pyrolysis, can stop cellulosic burning velocity.Therefore, though cellulose self is flammable, but a high proportion of nano combined salt component that mixes with it has played the effect of shield flame, make heat and cigarette in the process of charing burning be difficult for diffusion, when the final charing of fire resistance fibre, also only produce the smog and the carbon dioxide of minute quantity, and can not produce toxic gas (hydrogen chloride and halogen gas), environment friendly and pollution-free.The fundamental characteristics that has not only kept cellulose fibre, its filament intensity is 20～30% greater than 2.0Cn/dtex, elongate fiber rate, regain is 9～11%, and the heat-resistant fireproof effect obviously improves, limited oxygen index is brought up to more than 35% by 25～28% of prior art, instantaneous high temperature resistant by prior art 1000 ℃ are brought up to 1300 ℃, and serviceability temperature is brought up to 320 ℃ by 200～260 ℃ of prior art continuously, and smoke intensity is distributed density less than 0.6.And the elasticity and the ABRASION RESISTANCE of its product also increase, and purposes will be more extensive.
The specific embodiment:
Several different methods such as available mechanical lapping, chemistry are made nanometer additive respectively with silica, alundum (Al, but preferably prepare nanometer additive with the gas phase plasma processing method, the nanometer additive particle diameter of producing with this method is small, specific area is bigger, chemism is strong, cost is lower, is easy to mix.Get silica, the alundum (Al nanometer additive of regulation ratio (same prior art), mix with cellulose, make spinning solution, the weight of nanometer additive is preferably 20～30% of mixture weight, and desirable 20～30 kilograms nanometer additive mixes with the cellulose of 70～80 kilograms of morals.As use static mixer, and adopt the method for melt blending to prepare spinning solution, make the nanoparticle ratio be easier to be evenly dispersed in the spinning solution, and not oxidation, do not reunite.Can carry out spinning after making the nanometer spinning solution, produce and have cellulosic nature the fire resistance fibre of flame-retarding characteristic is preferably arranged again.
