Description
Technical field
The invention belongs to technical field of composite materials, relate to a kind of composite board and manufacturing approach thereof, relate in particular to a kind of thermoplastic composite plate and manufacturing approach thereof.The thermoplastic composite plate is applicable to that go along with sb. to guard him in large-scale place or traffic is gone along with sb. to guard him, and is mainly used in the security protection of livestock stable breeding, large-scale residential area, highway, large scale industry base and large-scale public place of entertainment.
Background technology
Go along with sb. to guard him in large-scale place and to go along with sb. to guard him with traffic; Need to use protective plate or guardrail, for example be used for the anticollision facility of the livestock stable breeding on the agricultural, large-scale residential area, highway, bridge, large scale industry base and large-scale public place of entertainment such as horse-racing ground, cycling track etc.
Go along with sb. to guard him with traffic and to be example, main what adopt is the road anticollision barrier, be mainly used in highway, bridge etc. fast road and bridge both sides and middle protection body.Existing road anticollision barrier adopts corrugated beam steeled protection fence basically.This guardrail adopts the corrugated cold-rolled steel sheet that has 2～3 half-waves as guardrail board usually; This protective plate overlaps each other or splices each other and by upright supports through connector; Or connect to form continuous road anticollision barrier structure through obstruction block and column; And the distortion that utilizes soil matrix, column, obstruction block, waveform protective plate comes progressively absorbing impact energy, forces errant vehicle to change direction.But the easy corrosion of this steel guard rail material surface, its appearance poor, service life lack, and also want regular full maintenance even stand intact, and comprehensive cost and maintenance cost are higher.And because the material hardness of steel guard rail is high, rigidity is big, the time of contact that errant vehicle and steel guard rail plate are bumped against is short, so energy absorption ability is relatively poor, and is bigger to vehicle and occupant's harm.
So, based on the above-mentioned defective of steel guard rail, the guardrail board that " to mould Dai Gang " processed has appearred, and promptly adopt plastic guardrail to replace steel guard rail.Like publication number is the Chinese patent " a kind of flexible pavement guardrail " of CN2350430A, discloses vibration damping property and flexibility that " B " font hollow-core construction that adopts PE plastic material slush moulding to form improves guardrail board.Publication number is that the Chinese patent " resin guardrail " of CN101023222A discloses through resin-molded and processes, and the hollow honeycomb panel-shaped base body that wavy cross-section, cross rib are alternately arranged makes guardrail board have higher-strength and shock-absorbing function.Above-mentioned guardrail board " to mould Dai Gang " though technical solution solved the easy corrosion of steel guard rail, appearance poor, service life is short, energy absorption ability is relatively poor, the problem bigger to vehicle and occupant's harm; But accomplish to prevent that vehicle from running off outside the road; The inevitable requirement guardrail has suitable mechanical strength and rigidity, just can keep out the collision of vehicle.Since the elastic modelling quantity of plastics have only steel 1/200th (about 190000Mpa like the elastic modelling quantity of carbon steel; The elastic modelling quantity of polyethylene (PE) is about 800Mpa); The guardrail of this all-plastic structure just needs to consume more material just can reach the intensity that steel guard rail requires; Therefore the volume of overall plastic guardrail is big, cost is very high, is unfavorable for promoting the use of.
" steel is moulded compound " is another kind of solution.Like publication number is to bury reinforcing bar or steel wire in the Chinese patent " highway protecting fence made of composite material and production method thereof " of CN1393600A has proposed, and with unsaturated-resin, auxiliary material, the compound guardrail of glass fiber layer of cloth mold pressing.Publication number is that the Chinese patent " road guard member " of CN2644499A proposes at steel plate or the band steel polymer material layer through the corrugated guardrail plate surface coverage compound extrusion moulding of clod wash machine-shaping.In the guardrail scheme of above-mentioned steel and plastic composite material, the compound mode of mold pressing can't be produced continuously, causes production efficiency lower; The extrusion molding on waveform steel guard rail plate surface, its technology comparatively complicacy rise its cost.Have the problem of compatibility between two kinds of materials of what is more important plastic-steel, cause the peel strength between the plastic-steel lower, use with installation process in be prone to because of plastic-steel separates, make guardrail board intensity and toughness deficiency, do not reach instructions for use and be prone to breakage; And plastics are different with the constriction coefficient that steel is expanded with heat and contract with cold; Expand with heat and contract with cold between the plastic-steel and can the relative slippage of appearance make the composition surface of the two have the space between back two kinds of materials; To cause moisture to get into the steel of corrosion inside along the space on composition surface from the breakage of material surface; Reduce the service life of guardrail board, and cause potential safety hazard.And above-mentioned plastic-steel guardrail all is the hard guardrail, or because of plastic-steel is easily separated can not rolling and bending, cause transportation and store inconvenience, and because of the guardrail board limited length, it is more that required accessory is installed, and makes its installation loaded down with trivial details.

Thermoplastic composite plate of the present invention is mainly used in the manufacturing safety barrier; Need burden energy absorption and two kinds of roles of non-disrumpent feelings protection, come the absorbing impact energy, alleviate injury vehicle and personnel through distortion; Change direction of traffic; When reducing causality loss to greatest extent, also to stop vehicle to run off highway, can not be disrumpent feelings.
Want not disrumpent feelings and prevent that vehicle from running off outside the road, the inevitable requirement guardrail has suitable mechanical strength and rigidity, just can keep out the collision of vehicle.And, hope that guardrail also will have certain pliability and shock-absorbing capacity from the angle consideration that the protection passenger escapes injury or alleviates extent of injury.Obviously, these two kinds of functional requirements are mutual contradiction.The design main idea of thermoplastic composite plate of the present invention just is creatively to satisfy the functional requirement of two kinds of mutual contradictions.
The present invention adopts the enhancing skeleton to make the thermoplastic composite plate have suitable mechanical strength and rigidity; And will strengthen skeleton and be placed on the center of thermoplastic composite plate or be offset to relative position away from mechanism, the enhancing skeleton has played supporting role to composite plate integral body also makes composite plate integral body have the crash-resistant strength and stiffness.And outside strengthening skeleton, adopted layer of thermoplastic material to realize cushioning effect; And combine the cold rolling moulding of extrusion molding structure and/or enhancing skeleton to design; In the starting stage of the mechanism distortion buffering of taking advantage of a situation progressively,, make flexible and rigidity is creatively brought into play its effect respectively in the different phase of hit impact protection process in a product in the superimposed shock resistance of distortion ending phase of mechanism; The thermoplastic composite plate of processing can vertically extended arbitrarily; Length confirms that arbitrarily the crooked rolling of ability has made things convenient for transportation and storage.Long length makes things convenient for guardrail to install, and reduces the use of guardrail connector.Also can very long thermoplastic composite plate be cut off and process piece.
The layer of thermoplastic material of thermoplastic composite plate has the composite construction of three layers of one; This structure has higher superior function: at first; Each layer has different functions, and the function of binder course is to be used for layer of thermoplastic material is better combined with the enhancing skeleton, makes them become integral body.The function of cushion is to cushion through its toughness and elasticity, after external force is collided, deformation only takes place, and does not produce fragmentation; In order to avoid produce the fragmentation that splashes in a large number, cause second accident, and combine the cold rolling moulding design of extrusion molding structure and/or enhancing skeleton; In the distortion of taking advantage of a situation progressively of the starting stage of mechanism, prolong the time of contact of vehicle and guardrail, the reduction impact peak value; Thereby can protect the personnel of vehicle, reduce the loss and injure.Overcoat is whole composite plate outermost layer structure, and its major function is anti-aging and wear-resisting, and its internal structure is protected.
Secondly, layer of thermoplastic material is the one composite construction with strengthening skeleton, and the one composite construction is meant that firm attachment becomes as a whole together between each layer not to be separated.The formation of integrative-structure is the adhesion that relies between the material.Binder course can strengthen formation one deck structure fine and close, strong adhesion on the skeleton surface; Simultaneously has better compatibility with cushion; Good compatibility makes and strengthens skeleton and the middle all stronger binding ability of cushion that overcoat and cushion also are to have the excellent compatibility ability, in manufacture process; Layer of thermoplastic material and strengthen and to adopt multi-layer co-extruded between the skeleton or extrude coating successively, and carry out cleaning surfaces and heat treated such as degreasing and rust removal to strengthening skeleton; Composition surface between each material layer can be not enough because of adhesion, surface impurity produces the space, and can prevent that grease from quickening the stress cracking of goods, thereby improved the compound reliability of thermoplastic and the service life of product.Its peel strength is higher, crooked and expand with heat and contract with cold after can not produce the relative slippage between the material layer, make its advantage that can give full play to thermoplastic composite, use and installation process in have higher intensity and toughness.In manufacturing and cold rolling forming process; Not easily separated between the material layer, be convenient to rolling and bending, made things convenient for transportation, storage and installation; And can carry out secondary punching and cold rolling moulding to comprising the thermoplastic composite plate that strengthens skeleton, punching place that product is strengthened on the skeleton coats layer of thermoplastic material continuously.Not separating between the thermoplastic composite plate each several part becomes an integral body, has strengthened shock resistance of thermoplastic composite plate and buffering ability greatly, has improved performance of products.Solved the bad problem of plastic-steel material compatibility in the prior art.
Thermoplastic composite plate of the present invention strengthens skeleton and mainly adopts elastic modelling quantity, hot strength to be far longer than the section bar of thermoplastic material; Section bar can adopt shape or other organic and inorganic reinforcing profiles; For example steel band, steel wire, polyester fiber, glass fibre, carbon fiber etc.; The advantage one that this material has is to improve the intensity of thermoplastic composite plate, strengthens under the effect of skeleton at big elastic modelling quantity and high tensile, and the thermoplastic composite plate can reach suitable mechanical strength and rigidity easily.When being used to make road safety barrier, can keep out the collision of vehicle, prevent that vehicle from running off outside the road.The 2nd, have simultaneously even to exceed the good shock resistance of thermoplastic material structure guardrail flexible, the advantages such as pliability of the elongatedness direction of extremely strong antiseptic power and appropriateness.The 3rd, raw-material consumption significantly reduces; Compare with the guardrail of all-plastic structure; Its material cost is less than 1/3rd of the all-plastic structure guardrail; The thermoplastic material that consumes makes the thermoplastic composite plate reaching flexible preferably and high-intensity while less than 1/5th of overall plastic guardrail, has practiced thrift raw material highly significant.The 4th, in a product, creatively satisfied the functional requirement of flexible and two kinds of mutual contradictions of rigidity.In the starting stage of mechanism; Impact flexibility preferably through layer of thermoplastic material; In conjunction with the extrusion molding structure of thermoplastic composite plate and/or the cold rolling moulding design that the strengthens skeleton progressively distortion of taking advantage of a situation; Realize cushioning effect, and can avoid guardrail and parts thereof to pierce through car body, jeopardize the occupant through the progressively distortion lodging of taking advantage of a situation of extrusion molding structure and/or enhancing skeleton.In the distortion ending phase of mechanism, the distortion stack through strengthening skeleton and the damping action of thermoplastic material have higher impact strength and shock-absorbing function, can prevent that vehicle from passing through guardrail or topple on guardrail.Ending phase in mechanism; Because the skin-friction coefficient of thermoplastic material is less, and combine the higher-strength and the shock-absorbing function of thermoplastic composite plate, and disposable the laying of long distance; Also help errant vehicle with less angle along the guardrail derivation of taking advantage of a situation, get back to traveling lane.Can the U.S. " the AASHTO Bridge guardrail instructs standard " (1988) along the important indicator that changes the errant vehicle direction slidingly as estimating guardrail the coefficientoffriction between guardrail and vehicle.
| μ | Estimate |
| 0～0.25 | Excellent |
| 0.26～0.35 | Good |
| ＞0.35 | Qualified |
The coefficient of friction of thermoplastic composite plate of the present invention can reach 0～0.35, and (coefficient of friction that on the PTFE resin, slides like steel is 0.1; The coefficient of friction that on the PE resin, slides is 0.2; The coefficient of friction that on the PS resin, slides is 0.35 etc.); According to this standard, the present invention can be along change the errant vehicle direction slidingly.
Manufacturing approach of the present invention is to adopt the one-step method production process of original creation; Multi-layer co-extruded or extrude coating successively with strengthening skeleton with the thermoplastic material employing of fusion; In compound extrusion die, once accomplish the shaping structures of the compound and guardrail board of two or more material; In conjunction with cleaning surfaces and heat treated such as skeleton flattens, degreasing and rust removal to strengthening; Combine between thermoplastic material and the reinforcing profile reliable, compound evenly, coat closely, expand with heat and contract with cold synchronously, but and rolling and bending.Vacuum cooled typing or roll extrusion cooling and shaping make the thermoplastic composite plate have advantages such as physical dimension is stable, coating is evenly smooth, and speed of production can reach 8 meters/minute.Can in～50～70 ℃ of scopes, use more than 30 years and keep material gloss, than traditional steel guard rail not only the life-span double, and non-maintaining throughout one's life, also can omit the complex surfaces anticorrosion process.
Through eliminating the serious installing hole of appearances in the thermoplastic composite plate and depart from the phenomenons such as the continuous transfer passage of enhancing skeleton of twisting, can't get into compound die with along its length material to strengthening the skeleton leveling.Through carrying uninterruptedly to strengthening skeleton, strengthen skeleton and thermoplastic material is multi-layer co-extruded or extrude coating successively, vacuum cooled is finalized the design or the roll extrusion cooling and shaping.Combine again to strengthen the skeleton one-off hole-piercing when needing processing mounting holes, comprise the thermoplastic composite plate secondary punching that strengthens skeleton, cold rolling moulding.Can be through continuous production; Obtain the thermoplastic composite plate of length, can not only composite plate rolling rolling be convenient to transportation; And the uninterrupted continuously thermoplastic composite plate that reaches length of producing; Can improve the installation effectiveness of guardrail, disposable the laying of long distance also reduced the guardrail board connector, practices thrift cost; And the flexible moderate compound guardrail board of thermoplastic also makes things convenient for the guardrail setting and the installation in road knee.Owing to do continuous sliding motion and disengaging when vehicle and rail collision.So require the contact-making surface of guardrail and vehicle to want smooth and do not have tangible protrusion.Disposable the laying of long distance; And combine the distortion lodging stack of extrusion molding structure and/or enhancing skeleton to eliminate the convexity that the guardrail board connector causes; Skin-friction coefficient in conjunction with thermoplastic material is less, and combines the thermoplastic composite plate to impact flexibility preferably in the starting stage of mechanism, at the ending phase higher-strength and the shock-absorbing function of mechanism; Reduced the coefficient of friction of vehicle and guardrail contact-making surface; Thereby prolong the time of contact of vehicle and guardrail, reduce the acceleration that subtracts of vehicle, reached the purpose of protection passenger safety.
