Description
Technical field
The present invention generally belongs to high performance composites technical field, relates generally to a kind of shellproof nonmetallic compound
Material plate and preparation method thereof.
Background technique
From the nineties in last century, ultra high molecular weight polyethylene fiber (UHME-PE) is in shellproof based article field as master
Material is wanted to be used widely.Wherein, had using the shellproof plate of ultra high molecular weight polyethylene fiber (UHMW-PE) manufacture
There is light-weight, ballistic performance to stablize, the advantages such as limit test V50 value is higher are applied to missile-resistant shield, bulletproof halmet, shellproof
The manufacture of a variety of professional ballistic-resistant articles such as plate and bullet-proof vehicle backplate.
Due to the higher high tenacity feature of ultra high molecular weight polyethylene fiber itself extension at break, although such plate can be with
Bullet is effectively intercepted, but the deformation after attack is bigger than normal, it is larger to point of impact peripheral structure damage envelope.It is continuous in rounds
Under the protection scene of shooting, if point of impact is excessively intensive, there is performance degradation risk caused by destroying because of structure.
With the development of material technology, the excellent polymer material of many shock resistance mechanics performances is led in engineering plastics
Mature application has been obtained in domain.Polyformaldehyde (POM) material is exactly a kind of engineering plastics of excellent in mechanical performance, and anti-reflective is rushed again
It hits performance and fatigue strength is very prominent, but polyformaldehyde (POM) material is too sensitive to notch shock, monomer material is not
Suitable for shellproof purposes.
In this case, it introduces the polymer material for having excellent mechanical performance and carries out compound, performance material advantage,
Material disadvantage bring risk is made up or evaded, the composite bullet-resistant plate based on ultra high molecular weight polyethylene fiber is become
The following R&D direction of material.
Summary of the invention
The purpose of the present invention is overcoming bullet resistant material deformation in the prior art excessive or the insufficient defect of shock resistance, one is provided
The shellproof nonmetallic composite plate of kind, the plate combination ultra high molecular weight polyethylene fiber delay bullet impact spy by deformation
Property and the anti-reflective of polyformaldehyde answer impact property and fatigue strength.
The technical scheme is that a kind of shellproof nonmetallic composite plate, it is out surface layer and support surface layer

Degree is higher than zinc and brass, close to steel；Wearability is good, coefficient of friction and water imbibition are small.
Further, above-mentioned polyformaldehyde plate with a thickness of 0.3mm-0.5mm.
Further, there is adhesive layer between above-mentioned out surface layer and support surface layer, the adhesive layer is aqueous poly- ammonia
The layer that ester lotion is formed by curing.
Use aqueous polyurethane as binder, have considered below: being elastomer after polyaminoester emulsion solidification, be conducive to
Structural integrity is kept during shock response；Polyurethane effect in conjunction with polyethylene surface is good, because polythene material is electrodeless
Property surface, the effect is unsatisfactory in conjunction with most of adhesive, and polyurethane binding, be in conjunction with polyethylene surface preferably
One kind；Using aqueous polyurethane, processing coating process is relatively convenient, because it is water dispersion lotion, is free of organic solvent emission,
It is easy meet the requirement of environmental protection.
Further, the mass ratio of above-mentioned out surface layer and support surface layer in overall structure is 12:1-4:1.
Further, the surface density of above-mentioned ultra high molecular weight polyethylene fiber laminated cloth is 140g/ ㎡.
The present invention also provides the preparation methods of above-mentioned shellproof nonmetallic composite plate, comprising the following steps:
S1, it ultra high molecular weight polyethylene fiber laminated cloth is replaced into orthogonal mode with interlayer carries out multiple-layer stacked, then
Under the conditions of 90 DEG C~110 DEG C, using 6MP~10MP pressure, the molding of fusion in 20 minutes~40 minutes is suppressed, is cooled to room temperature out
Mould takes out, and out surface layer is made；
S2, the uniform coated with adhesive of one side in polyformaldehyde plate dry 30 minutes~50 under the conditions of 60 DEG C~80 DEG C
Minute, to be bonded dose of curing degree reaches about 80%, forms glue film, i.e. adhesive layer, adhesive layer thickness control is in 0.1mm
Support surface layer is made in (± 0.02)；
S3, the coated with adhesive layer for supporting surface layer is bonded with out surface layer, under the conditions of 100~120 DEG C, uses 15MP
~25MP pressure, 10 minutes~30 minutes compacting connecting shapings are opened taking-up after being cooled to room temperature sizing, shellproof non-gold are made
Belong to composite board.
Shellproof nonmetallic composite plate of the invention is on the basis of ultra high molecular weight polyethylene fiber shellproof plate
The excellent mechanicals performances such as the intensity, rigidity, elasticity of polyformaldehyde are high, and resistance to repeated stock is high, restoration is good are combined, with tradition
Exclusive use ultra high molecular weight polyethylene fiber made of shellproof plate compare, when bearing bullet strike, utilize two kinds
Material combines the promotion of rear mechanical response efficiency, and plate body deformation caused by can be effectively reduced after attack makes punching caused by moment
It hits deformation and obtains efficient reply, so that bullet effectively reduces the structure damage envelope of point of impact peripheral position,
Under extreme condition, more efficient protection is formed to more dense bullet strike, is reduced because structure destroys bring performance after impact
Decaying.
