tape Section Design, the experience of the aspects such as system synthesis design ensure that good waterproof and dustproof, sound insulation, thermal insulation, cushioning effect.Sealed strip is easy for installation, solid and reliable, dodge gate switch is light.
Sealed strip, is sealed by a kind of thing, makes to be not easy to open, (Hebei Guang Te rubber item company limited) sealed strip, has paper, metal, various material.PVC adhesive tape price is relatively low, and because quality good or not differs, price is generally between 6000 yuan 15000 yuan/ton.Low-end product, owing to using waste material, substitute softening agent and high filler loading capacity, to making adhesive tape poor flexibility, easily hardening, having perverse nose taste, and easily migration makes frame material turn to be yellow, and work-ing life is short.Minority is in the door and window enterprise of low level price competition still in use.Middle and high end PVC adhesive tape can reach standard index, and work-ing life is also relatively longer.Because PVC product is halogen-containing, containing heavy metal in stablizer, therefore be unfavorable for environmental protection, therefore developed countries and domestic Beijing and coastal cities to be eliminated or restriction uses PVC adhesive tape equal the sixth of the twelve Earthly Branches.Weather strip for automobile is one of important spare part of automobile, is widely used in the positions such as car door, vehicle window, vehicle body, seat, skylight, engine case and boot, has waterproof, sealing, sound insulation, dust-proof, antifreeze, damping, warming and energy-conservation vital role.It must have very strong tensile strength, good elasticity, also needs reasonable temperature tolerance and ageing resistance.In order to ensure the fastening of adhesive tape and section bar, the section structure size of adhesive tape must be mated with section bar.Weather strip for automobile mainly by have favorable elasticity and incompressible distortion, ageing-resistant, ozone, chemical action, wider use temperature scope (-40 DEG C ~+120 DEG C) terpolymer EP rubber (EPDM) rubber pange and to be closely knitly composited, include unique metal fixture and ligulate button, sturdy and durable, be beneficial to installation.For a long time, automobile sealing strip requires to possess three zones: connectivity, stopping property and ornamental.Along with the progress of science and technology, the development of automotive industry, especially the continuing to bring out of brand-new material, the requirement of people to the feature of environmental protection of automobile, comfortableness, security, aesthetic property is more and more higher, also constantly to weed out the old and bring forth the new to the requirement of weather strip for automobile three zones in the past and is improving.For meeting the needs that passenger vehicle vehicle performance and class improve constantly, the development trend of door weather strip industry is analyzed, studied in the aspects such as the existing application material from objective automobile sealing strip, product structure and production technique.Before twentieth century eighties, due to the restriction of scientific and technological level at that time, nearly all weather strip for automobile, only considers to meet switching performance and part sealing property mostly, seldom considers ornamental, security and comfortableness.Therefore, the sealed strip that passenger vehicle used at that time is only considered more, as the sealed strip of front and rear windows, side window, car door in connectivity; Also very simple in structure, mostly adopt single glue kind, one connects vehicle body, and one connects glass etc.; Based on natural rubber or styrene-butadiene rubber(SBR), plastics (being mainly modified PVC) on material.Although such sealed strip meets switching performance and part sealing property, other performance is as all poor in elasticity, waterproof, noise control, isolation, dust-proof, heat-resisting, weather-proof, resistance to ozone, the aspect such as anti-aging, let alone aesthetic property and comfortableness.Due to the restriction of material self performance, automobile sealing strip only has 3 ~ 5 years work-ing life, can not match with the work-ing life of passenger vehicle; Color and luster is more single (rubber is almost whole-colored black) also, and be also just far from being ornamental and aesthetic property.The stopping property of car door, vehicle body, luggage room is all poor, and internal car noise is comparatively large, dust-proof, the effect also non-constant of waterproof.The later stage eighties, along with improving constantly of passenger vehicle class, to the requirement also corresponding raising of objective automobile sealing strip.From the eighties so far, automotive industry requires day by day to improve to the over-all properties of component industry, and certain sealed strip industry also grows a lot.Sealed strip product structure has had wide variation.Original single glue kind is changed into present two composite gum kinds (i.e. dense rubber and compound that is closely knit or rubber sponge), three matrix materials (i.e. the compound of dense rubber, rubber sponge and steel or polyamide skeleton), four matrix materials (i.e. the compound of dense rubber, rubber sponge and steel or polyamide skeleton, flocking four kinds of materials).The application of material has had new development.Abandon intensity, the natural rubber (or styrene-butadiene rubber(SBR)) that heat-resisting, weather-proof, resistance to deterioration is all poor and plastics, have employed the terpolymer EP rubber (EPDM) of synthesis.EPDM has excellent heat-resisting, weather-proof, ozone resistance.Due to the good characteristic of EPDM, so the equal sustainable growth of volume of production and marketing in recent decades.Production technique has taken leave of the original production technique that gum extrudes the sulfuration of vapour cure tank, have employed more advanced multi-machine heads and extrudes microwave vulcanization production technique, and injection secondary processing moulding process.Clearly, the primary of sealed strip is also that the most basic effect seals exactly, needs waterproof, every to make an uproar and dust-proof.In fact, sealing effectiveness is further enhanced by Curve guide impeller.The friction resistant of present material requires also more and more higher, to make sealing property can keep the longer time, also can reduce damage during initial installation.The Main Function of sealing makes as much as possible to be isolated from the outside in car, increases the riding comfort of officer and passenger to greatest extent.Should say, present sealed strip is all greatly increased than before twentieth century eighties in connectivity, stopping property, ornamental, security etc., but also there is certain gap in ornamental, the feature of environmental protection.The develop rapidly of automobile industry, has higher requirement to the various performances of automobile sealing strip.The development of science and technology, the application of novel material, novel process, for the development of sealed strip industry provides development space.Not only rest on connectivity, stopping property, ornamental three zones to the requirement of sealed strip, new requirement is proposed to the environmental protection, safety, Comfortable attractive etc. of automobile.This just requires that sealed strip is from the selection of material, the improvement of structure, and selecting of manufacturing process all needs to update.From the selection of material, not only rest in the application of EPDM.Relatively simple thermoplastic elastomer: the TPV (thermoplasticity vaporization elastomerics) of moulding process, TPE (thermoplastic elastomer), TPO (thermoplastic olefin) etc. are widely applied in some aspects.It is strong that they have tint permanence, plyability and returnability good, also can reach the requirement of environmental protection simultaneously.In a word, along with improving constantly of automobile class, the performance requriements also corresponding raising of passenger vehicle sealed strip.The reasonableness of structure, the hommization of design, the procedure of production technique, automatization, the security, the feature of environmental protection, returnability, supporting aesthetic property, diversity etc. of product are all the key propertys that passenger vehicle sealed strip needs to consider.
Stopping property is an important indicator of vehicle complete vehicle quality, one of the important spare part of this index quality and weather strip for automobile product is resolved just, it is widely used in the vehicle body positions such as windscreen before and after automobile, car door, vehicle window, initiation cabin, boot, fill up the gap between car body component, there is the functions such as damping, waterproof and dustproof, sound insulation, decoration, maintenance effect is played to driver and conductor and car load.The classification of weather strip for automobile product has various ways, and title, data kind, complex document quantity, performance characteristics etc. usually according to device position (parts) usually will stop classification.Title classification wherein according to device position (parts) is the most frequently used mode, and it comprises initiates sealed strip, side window sealed strip, Foof weather strip, covering for roofs sealed strip, boot (luggage) sealed strip etc. inside and outside cabin sealed strip, front and rear windows sealed strip, door frame sealed strip, door weather strip, glass guide way of vehicle door sealed strip, bottom of door dust excluder, car door windowsill.Weather strip for automobile industry consumption number of the enterprise is numerous, and scope is less, is also difficult to formation scope weather, differs greatly with the enterprise of external similar tens yuan of volumes that stop doing business easily.Meanwhile, along with the recovery gradually of international economy, the demand for exports amount of weather strip for automobile also can increase year by year, bursts out after baptism in the market of weather strip for automobile industry blowout formula in 2009 in experience, will welcome one period of fast open duration of an exhibition.The particularly beginning second half year from 2009, Ge great weather strip for automobile enterprise obviously feels the famine of production capacity own, numerous and complicatedly identifies oneself with in the middle of the ranks of enhancing production capacities, and the time have activated weather strip for automobile device fabrication enterprise, hold the equipment order of handle greatly in hand, feel more the difficult and important of friendship phase.But, promoting the time-division of production capacity, necessarily can not just think of solution Most Urgent at the moment, and the key elements such as progressive work rate of consumption, increased quality, product configurations promotion, technical progress should be separated, the comprehensive production capacity of General Promotion enterprise.Need not doubt, Chinese Auto Industry restructuring is trend of the times, and as the weather strip for automobile enterprise in automotive industry industrial chain downstream, its merging and reorganization is also unavoidable, as long as also like this, domestic weather strip for automobile enterprise ability is run business big and strong.First, the weather strip for automobile consumption enterprise resources advantage can applied each other stops whole merger to form cluster advantage, grows the strength of enterprise, secondly, weather strip for automobile consumption enterprise provides for car load is supporting to serve, and go in the R&D process that must get involved in car load product, as long as ability produces the understanding more deepened to weather strip for automobile product like this, the weather strip for automobile product researched and developed just has more specific aim, ability makes the yield and quality amount of the further satisfactory weather strip for automobile of automobile main frame maker: the 3rd, the theme of environmental protection also should be coiled in weather strip for automobile consumption enterprise, with stop between upstream and downstream firms generally cooperating, advance new data, novel process, the application of new technology, and the industrial chain of weather strip for automobile industry is extended with this.
