The invention belongs to the technical field of ultra-high molecular weight polyethylene fibers, and particularly relates to an anti-mosquito flame-retardant ultra-high molecular weight polyethylene fiber and a preparation method thereof.
Background
Ultra-high Molecular Weight Polyethylene Fiber (UHMWPE for short) and carbon Fiber and aramid Fiber are called as three high-performance special fibers in the world, and are the lightest high-performance Fiber in the world at present and the Fiber with the highest specific strength and specific modulus. The ultra-high molecular weight polyethylene fiber also has excellent performances such as outstanding high modulus, high strength, impact resistance, low temperature resistance, self-lubricity and the like, and can be widely applied to multiple fields such as military industry, marine industry, aerospace, safety protection, sports industry and the like.
With the steady development of social economy and the improvement of the living standard of people, the health consciousness and the life safety consciousness of the people are continuously enhanced. Due to the excellent performance of the ultra-high molecular weight polyethylene fiber, the demand of the civil market is rapidly increased, and the application field is gradually expanded. In the fields of protective articles and the like, the mosquito prevention and flame retardant performance of civil fibers have certain requirements, and the modification of the ultra-high molecular weight polyethylene fibers in the past is less related to the modification of both the mosquito prevention and the flame retardant performance. Chinese patent 109385689 discloses a spinning method of blended ultra-high molecular weight polyethylene, the strength of which can reach 14-28 cN/dtex, but the anti-mosquito and flame retardant effects on the fiber are not involved; chinese patent 112359436 discloses a flame-retardant ultra-high molecular weight polyethylene fiber, which discloses a nano additive comprising white carbon black, nano calcium carbonate and nano montmorillonite, which can be compounded with flame-retardant ultra-high molecular weight polyethylene, and meanwhile, the nano additive is modified by containing silane or titanic acid substances to improve the compatibility between mixed materials, the obtained fiber belongs to a flame-retardant material, the oxygen index is higher than 27%, but the multi-effect function of mosquito prevention and flame retardation is not involved; chinese patent 109371475 discloses a spinning method of ultra-high molecular weight polyethylene, which is to uniformly disperse nano montmorillonite, nano kaolin or nano graphene in the ultra-high molecular weight polyethylene, and add peroxide initiator and organic solvent to obtain a mixed material for granulation, wherein the breaking strength of the obtained fiber is 14-28 cN/dtex, and the anti-mosquito and flame retardant effects of the fiber are not involved; chinese patent 112626634 discloses an injection molding mosquito-proof ultra-high molecular weight polyethylene fiber and a preparation method thereof, the viscosity average molecular weight of the ultra-high molecular weight polyethylene adopted in the patent is up to 350-600 ten thousand, and the material is difficult to disperse uniformly, so that other lubricating substances are required to be added to reduce the van der Waals force among molecular chains to improve the fluidity of the material, the production cost is increased in the process, and the process is complex; chinese patent 103613830 discloses an antistatic halogen-free flame-retardant UHMWPE/graphene composite material and a preparation method thereof, wherein solvents such as tetrahydrofuran, trichloromethane and the like are required to be adopted in the production process, the production process is complex, the environment is polluted, the energy consumption is large, and multiple effects of flame retardance and mosquito prevention are not realized; chinese patent 107558170 discloses a method for preparing flame-retardant UHMWPE fibers, wherein an organic reagent is used to soak ultrahigh molecular weight polyethylene fibers, and further an activation treatment is performed, which increases the cost of waste liquid generated during the process, and at the same time, the process is complex, and the multiple-effect integration of flame-retardant and mosquito-proof is not realized. In summary, the ultra-high molecular weight polyethylene fiber in the prior art cannot completely realize the stable function of flame retarding and mosquito preventing. On the other hand, at present, the gel spinning method is mainly adopted in industry to prepare the ultra-high molecular weight polyethylene fiber. Compared with the gel spinning method, the melt spinning method for preparing the fibers is simpler in process, free of pollution to the environment, lower in production cost, high in production efficiency and low in energy consumption, so that the melt spinning method is the most environment-friendly, most economical and highest-yield method for preparing the ultrahigh molecular weight polyethylene fibers. However, since the ultra-high molecular weight polyethylene has an ultra-high molecular weight, and a large amount of entanglement exists among polyethylene macromolecular chains, the macromolecular chains of the ultra-high molecular weight polyethylene are difficult to slide, have an extremely high viscosity in a molten state, and have almost zero melt flowability, which brings great difficulty to the preparation of the ultra-high molecular weight polyethylene fiber by a melt spinning method. Therefore, how the ultra-high molecular weight polyethylene fiber has excellent mosquito-proof and flame retardant properties, and the problems of complex production process flow, high production cost and the like of the ultra-high molecular weight polyethylene fiber in the preparation process are solved, and the method is of great importance to the ultra-high molecular weight polyethylene fiber and the application field thereof.

The invention adopts the anti-mosquito agent which is mainly a natural organic anti-mosquito agent, the heat-resisting temperature of the anti-mosquito agent can reach more than 260 ℃, and the anti-mosquito agent needs to keep good stability in the melting process, and the natural organic anti-mosquito agent can be well protected in the modified nano additive, so in order to reduce the thermal decomposition failure of the anti-mosquito agent in the melting process and simultaneously achieve good anti-mosquito effect, the invention adopts nano particles with higher specific surface area to adsorb and load the anti-mosquito agent, thereby improving the stability of the natural organic anti-mosquito agent in a mixture, reducing the thermal decomposition of the natural organic anti-mosquito agent, reducing the dosage of the anti-mosquito agent and further prolonging the anti-mosquito effect.
