丁基橡胶瓶塞硫化收缩率研究

70模具工业2006年第32卷第3期贺靖勇(株洲工学院信息与计算科学系,湖南株洲412000):介绍了影响橡胶硫化收缩率的因素,以28-B橡胶瓶塞为例,研究了丁基橡胶瓶塞硫化收缩率的确定方法模芯公差范围确定的方法,最后确定了28-B橡胶瓶塞的模芯尺寸和公差范围,在生产过程中取得了较好的经济效益:硫化;收缩率;模芯公差;橡胶瓶塞:TQ330.41:B:1001-2168(2006)03-0070-04ResearchofVulcanizingShrinkageValueofButylRubberBottleClosureHEJing_yong(DepartmentofInformationandComputerScience,ZhuzhouInstituteofTechnology,Zhuzhou,Hunan412000,China)Abstract:Theconceptofrubbervulcanizingshrinkagevaluewasindicatedandtheinfluencingfactorswerediscussed.Thedeterminationofthevulcanizingshrinkagevalueof28_Bbutylrubberbottleclosureandofthetolerancerangeofmoldcorewasanalyzedandgoodresultswereachieved.Keywords:vulcanizing;shrinkagevalue;moldcoretolerance1,,,,,,5,3.5MPa;,9,0.5MPa,10,,15,DP23MPa,,,,5,4,5.04MPa,DP14.5MPa,128,,,,,,1,,2,55,5,,,,,,,,,,,,,,:[1].[K].:,2003.[2].[K].:,2003.[3].[K].:,2003.[4].[K].:,2003.71模具工业2006年第32卷第3期,,,,,,,,,,2(1)1B,,,1,2,,33.1,,,,k:k=[(D-D1)/D]100%(1)k!!!D!!!D1!!!():D=D1/(1-k)(2),:D=(1+k)D1(3),,(3),,,3.23.2.1硬度影响,90,40~60,50!!!!!!!!!!!!!!!!!!!!!!:(1970-),,,,,::13973340702,:[e-mail]:2005-04-16128-Bmmd212.0d37.0h43.0h28.0a7∀28d118.0#0.2d426.6#0.3h33.8#0.3h111.8#0.4228-Bmm72模具工业2006年第32卷第3期3.2.2填料影响,,3.2.3硫化温度及硫化程度影响,,165~185∃,,3.2.4模具结构影响,,,,,0.2%~0.6%,5mm3.2.5其他因素影响,,,,,44.1HT1066100ZnO5SA1ZDC0.1MgO0.1TiB2.8SRF0.2MLE3.0GYT1004.2TM40MVC/D_40XLB_DZ(R)400X400/2;:ASTMD9554.3%%%(%(24h)%(23∃):170∃,:1.6kN55.1,IIR1.5%~2.2%,1.7%,1/3,,,,,1/4~1/8,5.23,12,2,,,3mmd118.30~-0.05d4270~-0.06h33.860~-0.06h412#0.0873模具工业2006年第32卷第3期6(1),,,,,,(2),:,,,,(3)(),,,,,;,(4),,,:[1],,.()[K].:,1989.[2].[K].:,1996.&()!∋2006118,&()!∋,CEO,200(CIMS),,GILDEMEISTER,10,,200,,NEF400,DMU50DMC635VDMC64Vlinear,,,,,,(SECO);(TECNOMAGNETE);(BLUM)(BLASER),(郑利文报道)!!!
