By means of the fluid barrier material, the compatibility and the stability of the STF and the armored fabric are improved; meanwhile, the technical problem that as the STF has the fluidity and is prone to downwards flowing under the effect of the gravity, the barrier performance at the upper portion of the armored fabric and the barrier performance at the lower portion of the armored fabric have great difference is solved, and the overall barrier performance of the fluid barrier material is improved.
Description
Technical field
The present invention relates to shellproof guard technology field, particularly a kind of liquid-state protective material and preparation method thereof.
Background technology
STF (shear thickening fluid is called for short STF), being a kind of new function material, is the liquid of thickness slightly in normal state.When being subject to percussion, generate because hydrodynamics overcomes interparticle repulsive force effect a kind of metastable " Particle Cluster ", these " Particle Cluster " grow up with the increase of fluid force educational level, it is separately made system volume become large by decentralized medium, macro manifestations is that apparent viscosity sharply increases, even discontinuous rising, presents the shock resistance of solid; And after impulsive force reduces, return to rapidly again original flexible state, this process has invertibity.
The liquid utilizing STF liquid and high-performance fiber armored fabric compound to be prepared into is shellproof, visit and sting material; there is the advantages such as light weight, pliability is good, volume is little; effectively can break through the limitation of the hard heaviness of existing protective materials; and can the position of flexible motion be needed to provide protection for human body, and do not affect its activity.The successful exploitation of liquid flak jackets; not only can improve the problem existing for existing protective materials to a great extent; for the life security of the high-risk occupational populations such as soldier, police and security personnel provides stronger protection, more can significantly promote modernization of national defense level.Develop the liquid-state protective clothes with excellent barrier propterty, its key technical problem and difficult point are not only the preparation of STF, but also GPRS STF in shellproof base fabric evenly, the stable and technology of continuous distributed.
Mostly studying mainly at present, STF liquid is carried out compound by the methods such as dip coating and high-performance fiber armored fabric prepares composite protective material, and then this composite is carried out multiple-layer stacked thus obtained Novel protective material.If STF and high-performance protective fabric are only by simple impregnation method compound, armored fabric in use, because STF has mobility, when being subject to Action of Gravity Field, very likely flow downward, thus cause the upper and lower barrier propterty of fabric to have larger difference, have a strong impact on its serviceability, and compatibility between the two and stability all poor.In addition, the STF liquid on armored fabric surface causes STF liquid proportion of composing to be not easy to control because of factors such as absorption, infiltrations, affects the barrier propterty of material.Impregnation method required time is longer, and the shear thickening behavior of STF liquid in dipping process, composition change easily occurs and affects the performance of its barrier propterty.
Summary of the invention
The present invention is intended to overcome in existing liquid-state protective material, compatibility and poor stability between STF liquid and armored fabric, the technological deficiency that barrier propterty is not good, improve compatibility and the stability of STF liquid and armored fabric, solving because STF has mobility simultaneously, when being subject to Action of Gravity Field, easily flowing downward, thus cause the upper and lower barrier propterty of fabric to have the technical problem of larger difference, improve the integral protection performance of liquid-state protective material.
