Abstract

The invention relates to the technical field of complexing agents, in particular to an epoxy resin complexing agent for metal joint filling and a preparation method of the epoxy resin complexing agent. Each part of the complexing agent is prepared from the following raw materials in parts by mass: 78 to 86 parts of epoxy resin, 27 to 33 parts of inorganic filler, 7 to 9 parts of polydimethylsiloxane, 6 to 10 parts of polyazelaic anhydride, 2 to 4 parts of dibutyl adipate, 8 to 9 parts of butyl glycidyl ether, 12 to 20 parts of curing aid, 7 to 8 parts of silane coupling agent, 46 to 54 parts of deionized water and 12 to 16 parts of ethyoxyl lauramide. The preparation method comprises the following steps: S1, weighing the raw materials for later use; s2, adding the components of the curing aid into the reaction kettle, stirring uniformly at the rotating speed of 80-100r / min, and taking out for later use; s3, putting the rest raw materials into the reaction kettle, and stirring at the rotating speed of 100-120r / min until the raw materials are uniformly mixed, so as to obtain mixed slurry. The antistatic effect of the complexing agent can be improved.

Description

technical field [0001] The invention relates to the technical field of composite agents, in particular to an epoxy resin composite agent used for metal caulking and a preparation method thereof. Background technique [0002] Gaps are easy to appear in the joints of metals and other objects. After a long time, the gaps will gradually expand, so that the connection performance will be the lowest in the end, and after the installation is completed, caulking will be applied to the joints. The additives used to fill the gaps and enhance the compression and anti-wear properties of the gaps. However, in a dry environment, the gaps are filled with additives, which may cause more dust to be absorbed at the gaps. Therefore, we propose an epoxy resin composite for metal gap filling and its preparation method. used to solve the above problems. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the shortcomings existing in the prior art, and propose an...
