Abstract
The present invention relates to a method for preparing a thermoplastic nonmetal bulletproof compound material by using high-strength polyvinyl alcohol (PVA) fiber. High-strength PVA fiber is made into a no-weft fabric and a plain-grain fabric. The thermoplastic resin, such as PE, PU, EVA, PVB, etc., is used for being compounded with aromatic polyamide fiber to form different structures to be pressed into a laminated bulletproof board for 10 to 30 minutes at the temperature of 130 to 190 DEG C. A target board of which the area is 15*15cm<2> and the surface density is 9.3 kg/m<2> is made of full PVA fiber compound materials and can proof the bullet of which the speed is 380 m/s. When the consumption of the aromatic polyamide fiber is not higher than 30%, the bullet of which the speed is 420 m/s can be proofed. When the consumption of the aromatic polyamide fiber is not higher than 50%, the bullet of which the speed is 460 m/s can be proofed. A 54-type pistol and a 51-type lead cord bullet are used for shooting in the distance of 5 meters.
Description
Technical field
The invention belongs to the nonmetallic composite field, is the method for preparing the non-metallic fibers ballistic composite.This method can be used for making military helmet, also can be widely used in building, mine and individual protection field such as anti-riot.
Background technology
The modern military helmet has experienced the evolution from steel helmet to the fibre reinforced composites helmet.Steel helmet is cheap, but weight is heavier, and shellproof and heat-proof quality is poor, wear uncomfortable, the danger that has secondary fragment to hurt sb.'s feelings.The fiber reinforcement nonmetallic composite helmet mainly contains the nylon helmet, the glass fibre helmet, aramid fibre (Kevlar) helmet, ultra-high molecular weight polyethylene (UHMWPE) helmet etc.The nylon helmet, the overall ballistic performance of the glass helmet are relatively poor; Kevlar helmet bulletproof ability is strong, in light weight, but price is higher.The UHMWPE fiber is the fiber of present mechanical property the best, but price is also high, and the compoiste adhering technical difficulty is big.China also fails ultra-high strong fibers such as suitability for industrialized production Kevlar, UHMWPE at present, and the nonmetal bulletproof composite that the development bulletproof ability is strong, price is fit to China's national situation is to dwindle and world-class gap.China is the country that PVA output is the highest in the world, production process route is more complete, and actual production capacity reached 32.5 ten thousand tons in 1996.At present, the existing brute force of Japan is the PVA commercial fibre of 18g/d.Theory analysis and experimental result show that the intensity of PVA fiber also can further improve.Develop high-strength PVA fiber bulletproof composite,, reduce cost, revitalize national industry, have great importance for improving my army of army helmet protection level.
Summary of the invention
The objective of the invention is to provide a kind of method of high-strength PVA fiber production thermoplastic non-metal ballistic composite at the deficiencies in the prior art.High-strength PVA fiber is made no latitude cloth and two kinds of forms of plain, select PE, PU, thermoplastic resins such as EVA, PVB,, minute be pressed into the laminating bulletproof plate in temperature 130-190 ℃, 10-30 with the different structure of the compound composition of aramid fibre.
Purpose of the present invention is realized by following technical measures:
A kind of method of preparing thermoplastic non-metal bulletproof composite material from high-strength polyvinyl alcohol
(1) the PVA one-way fiber does not have the preparation of latitude cloth and plain weave woven cloths
The unidirectional no latitude cloth of PVA is that high-strength PVA fiber and polyethylene, polyurethane or the polyvinyl alcohol bonding agent of 18g/d made with brute force, and bonding agent is the 3-10% of fibre weight; The PVA plain is weaved with heavy pound arrow shaft loom;
(2) preparation of PVA/ aramid fibre/PVA sandwich structure armour
This armour by before, during and after three parts form, anterior do not have PVA that latitude cloth stacks by orthogonal manner or the PVA plain successively stacks, each interlayer lay PE or eva film, film are the 15-40% of fibre weight; The middle part successively stacks the aramid fibre plain, and the aramid fibre consumption is no more than 50%, and each interlayer lay PVB or PU film, film are the 15-40% of fibre weight; The rear portion successively stacks the PVA plain, each interlayer lay PVB or PU film, film is the 15-40% of fibre weight, fiber becomes with the structural group of binding agent respectively not have latitude cloth or PVA plain/aramid fibre/PVA plain and PE or EVA/PVB or PU/PVB or PU with PVA and represent, on platen-press in temperature 130-190 ℃, compression moulding in 10-30 minute.
The attack test: the May 4th pistol, 51 formula lead for retractable pencil bullets, 5 meters distance shootings show, are 15 * 15cm to area
2, surface density is 9.3kg/m
2Target plate, the aromatic polyamides consumption is no more than 30%, can shellproof fast 420m/s; The aromatic polyamides consumption is no more than 50%, can shellproof fast 460m/s.The target plate outward appearance meets the requirements after the attack, and bulge is little.
The present invention has following advantage:
1. adopt PVA do not have latitude cloth or plain/aromatic polyamides/PVA plain sandwich structure and with the mode of resin compounded of the same race not, its bulletproof effect is better than traditional complex method.
2. armour adopts the thermoplasticity processing technology, and technology is simple, and defect rate is low, pollutes little.
3. the present invention is expected to need the field of individual protection to obtain to use in building, mine and anti-riot etc.
The specific embodiment
By the following examples the present invention is specifically described, what be necessary to illustrate is: following examples only are used for the present invention is further specified, and can not be interpreted as limiting the scope of the invention.Those skilled in the art can make some nonessential improvement and adjustment to the present invention by foregoing according to the present invention.
