(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

為適應(yīng)國內(nèi)汽車工業(yè)發(fā)展的需要,單組分聚氨酯密封膠擋風(fēng)玻璃膠被列為“八五”國家重點(diǎn)科技攻關(guān)單組分聚氨酯密封膠新品種開發(fā)項(xiàng)目之一。國內(nèi)最先開發(fā)成功該種單組分聚氨酯密封膠的單位他們合作研制的聚氨酯單組分聚氨酯密封膠/密封膠于1993年秋通過省級(jí)中試產(chǎn)品成果鑒定,其后ORB-P系列單組分單組分聚氨酯密封膠,并在1998年通過原化工部成果鑒定。
我國聚氨酯擋風(fēng)玻璃膠的開發(fā)應(yīng)用在上世紀(jì)90年代后期得到了快速發(fā)展,一方面,國內(nèi)單組分聚氨酯密封膠行業(yè)相關(guān)廠家引進(jìn)國外先進(jìn)技術(shù)和設(shè)備投入生產(chǎn),如引進(jìn)瑞士Sika公司技術(shù)和設(shè)備生產(chǎn)的AM-140聚氨酯擋風(fēng)玻璃膠、引進(jìn)德國技術(shù)和設(shè)備生產(chǎn)的聚氨酯擋風(fēng)玻璃膠、引進(jìn)德國設(shè)備生產(chǎn)的JS-316聚氨酯檔風(fēng)玻璃膠等;另一方面,國外著名單組分聚氨酯密封膠廠家在國內(nèi)建立合資企業(yè),將其品牌聚氨酯擋風(fēng)玻璃膠產(chǎn)品在國內(nèi)生產(chǎn),如F502聚氨酯擋風(fēng)玻璃膠、8590聚氨醞擋風(fēng)玻璃膠、V3聚氨酯擋風(fēng)玻璃膠等,此外,還有國外獨(dú)資公司的這類產(chǎn)品在國內(nèi)生產(chǎn)和銷售,像聚氨酯擋風(fēng)玻璃膠等,總之,聚氨醞擋風(fēng)玻璃膠的開發(fā)應(yīng)用目前已是一個(gè)國內(nèi)外多品牌產(chǎn)品匯集和競(jìng)爭(zhēng)的時(shí)代。
自上世紀(jì)90年代后期以來,單組分聚氨酯擋風(fēng)玻璃膠的使用性能和工藝性能不斷得到改進(jìn)提高。使用中取消漆面底膠、只需配用玻璃底膠的單組分聚氨酯擋風(fēng)玻璃膠,最早的是F502聚氨酯擋風(fēng)玻璃膠。提高車身剛度的高模數(shù)膠、改善鋁結(jié)構(gòu)車身乘坐舒適性和使用耐久性的低導(dǎo)電膠和更易在生產(chǎn)線進(jìn)行玻璃安裝的瞬時(shí)定位型膠,都是開發(fā)應(yīng)用的新品。對(duì)于加快該類膠固化速度方面的研究,除改進(jìn)單組分聚氨酯密封膠主體成分的分子結(jié)構(gòu)和膠的配方以外,還對(duì)加熱和能源裝置進(jìn)行了大量研究,近年來,研究成功遠(yuǎn)紅外、微波、高頻加熱裝置,使固化速度成倍加快。最新研發(fā)成功的U1201F低溫低濕快固型單組分濕固化聚氨酷擋風(fēng)玻璃膠,則更適用于生產(chǎn)車間沒有保暖條件的大客車擋風(fēng)玻璃的裝配。目前單組分聚氨酯密封膠擋風(fēng)玻璃膠研究、生產(chǎn)和應(yīng)用呈現(xiàn)向高性能、多品種、系列化發(fā)展的態(tài)勢(shì)。http://www.m.n5224.cn/
