一种单组份预涂型厌氧胶及其制备方法
摘要：
本发明一种单组份预涂型厌氧胶及其制备方法。属于预涂厌氧胶技术领域。它主要是解决现有双组份预涂厌氧胶存在混合后不稳定、混胶不均等的问题。它的主要特征是：包含：(A)35％～50％Wt含有至少1个乙烯基封端的不饱和单体；(B)35％～60％Wt水；(C)3～10％Wt水溶性增稠剂；(E)0.01％～3％Wt聚合反应促进剂；(F)0.5％～2％Wt颜料；(G)3％～15％Wt填料；(H)1％～5％Wt成膜助剂；(I)0.5％～5％Wt微胶囊引发剂。方法：将(A)、(B)、(C)投入反应釜搅拌均匀；加入(E)、(F)、(G)搅拌均匀；加入(H)搅拌；加入(I)低速搅拌，使(I)混合均匀；抽真空-0.09MPa左右；包装避光贮存。本发明具有单组份的特点，广泛应用于各种机械工业螺纹紧固件的锁固和密封等。
摘要（英）：

The invention relates to a single component pre-coated type anaerobic adhesive and a preparation method thereof, belonging to the technical field of pre-coated type anaerobic adhesive, and mainly aiming at solving the problems that the existing double-component pre-coated type anaerobic adhesive is unstable after being mixed and uneven in adhesive mixing. The single component pre-coated type anaerobic adhesive is mainly characterized by comprising: (A) 35-50%wt of unsaturated monomer containing at least one vinyl-terminated, (B) 35-60%wt of water, (C) 3-10%wt of water-soluble thickening agent, (E) 0.01-3%wt of polymerization promoting agent, (F) 0.5-2%wt of pigment, (G) 3-15%wt of filler, (H) 1-5%wt of film forming auxiliary agent and (I) 0.5-5%wt of microcapsule initiator. The preparation method comprises the steps of: adding (A), (B) and (C) into a reaction kettle and evenly mixing; adding (E), (F) and (G) and evenly stirring; adding (H) and stirring; adding (I) and stirring at low speed, and leading (I) to be evenly mixed; vacuumizing to about 0.09MPa; and finally, packaging and storing in a way of keeping the products out of the sun. The invention has the characteristic of single component, and can be widely applied to locking, sealing and the like of various mechanical industry thread fasteners.
