摘要
煤矸石中的主要矿物质是高岭石等黏土。高岭石结晶度的好坏对于煤矸石的应用起着极其重要的作用。通过XRD、FTIR、SEM等测试手段分析发现,大同煤矿集团塔山矿区开采出来的煤矸石中的高岭石含量高且结晶度较好,属于有序至高度有序范围内,可以通过插层等手段生产纳米级煤系高岭土等深加工产品。
In this article modified fluorinated polyurethane elastomers are synthesized by reaction of fluorinated polyether ZDOL- 1 000, and toluene diisocyanate or isophorone diisocyanate is modified by trime thylolpropane mono allyl ether and self-made extender. The thermodynamic properties and mechanical properties of fluorinated polyurethane samples are characterized. The investigation of adhesive properties of samples are carried out. Results indicate that the adhesion of fluorinated polyurethane increased by light-curing when trime thylolpropane mono allyl ether and self-made extender are used as extenders. The trime thylolpropane mono allyl ether is more conducive to enhance the adhesion, especially in systems of toluene diisocyanate.
