胶粘剂概况(国外英文资料) Common epoxy resins are: bisphenol A is the most typical, linear cresol type, phenolic epoxy resin, etc. Amine curing agent of them with epoxy group in the polymer chain to open polymerization, anhydride curing agent is with the esterification reaction of hydroxyl polymer chain, eventually form a three-dimensional network structure. Common isocyanates: MDI, TDI (which, without affecting performance, can use MDI, no longer TDI) TDI is low, volatile, and highly toxic. The small pieces of material (such as PP, PP, fluoroplastics, etc.) are small. Website with efficient and professional team, excellent service, enterprise and interaction with the exchange of personnel to provide information services for adhesive, the adhesive enterprise human resources adhesive used to its overall development strategy, but also promoted the adhesive talent livelihood planning career development in order to realize his professional life. Shao A15 ~ shao D90 2 mechanical performance high 3 wear-resisting, anti-impact high. BR . Heat sulfide silica gel: the base glue is high molecular weight polysiloxane, which is used as crosslinking agent. 4 silica gel; It can be divided into three types: heat sulfide, room temperature sulfide (condensation type) and addition reaction type; Small percentage of solidified volume; 6 weather-resistant, weather-resistant 7 resistant to biological aging; Disadvantages: high temperature, high humidity, easy to hydrolyzed silica gel. Good electrical performance. The strength of the bonding strength depends on three basic factors: the cohesion strength of 1 adhesive. The bonding process 1 wetting: to make the surface of the sticky surface easily wetted, it needs to be cleaned and treated to remove the oil. Anaerobic solidification: in the case of isolated air, free radical polymerization occurs, and the presence of air can hinder the polymerization. At room temperature, silica gel is divided into single and two-component parts. ; The latter can b
