通过对生胶、硫化胶上侵蚀橡胶微生物的分离、筛选、鉴定、获得了攻击橡胶能力强的细菌有地衣芽孢杆菌(Bac. lichenformis)等5个种;霉菌有黄曲霉(Asp. flavus)等7个种及放线菌有灰色链霉菌(S. griseus)等9个种。在侵蚀橡胶能力及耐药性上,混合菌都比单一菌强。抗药性以细菌最强,霉菌次之,放线菌最弱。橡胶抗菌侵蚀性能,生胶按天然胶、丁苯胶、丁基胶、氯丁胶、丁睛胶、聚硫胶顺序;硫化胶按丁苯、氯丁、丁睛橡胶次序递增。按杀菌剂的杀菌力、持久性、同橡胶配合剂反应及对橡胶物理机械、老化等性能影响,及从价廉、低毒及稳定性比较,最终推荐用五氯酚锌(PR_2)为橡胶杀菌剂。加2—5％该药剂的防水丁睛胶有良好抗菌性,也不影响其物理机械性能。
By isolating, screening and identifying eroded rubber microorganisms on raw rubber and vulcanized rubber, five kinds of bacteria capable of attacking rubber such as Bacillus lichenformis were obtained; Aspergillus flavus and the like Seven species and actinomycetes have S. griseus and other nine species. In the erosion of rubber capacity and resistance, the mixed bacteria are stronger than single bacteria. Resistance to bacteria strongest, followed by mold, actinomycetes weakest. Antibacterial properties of rubber, raw rubber by natural rubber, styrene butadiene rubber, butyl rubber, neoprene, Dingjiao plastic, polysulfide order; vulcanized rubber butyl benzene, neoprene, butadiene rubber order increase. According to the bactericidal and bactericidal effect of bactericide, the reaction with rubber compounding agent and the physical, mechanical and aging properties of the rubber, the final recommendation is to use zinc pentachlorophenol (PR_2) as rubber Bactericide. Add 2-5% of the waterproofing agent has good antibacterial anti-bacterial, it does not affect the physical and mechanical properties.
