Problems solved by technology

[0003] When the bolt is in normal use, because it is directly in contact with concrete and other media, the corresponding steel glue must be used for routine use, so as to ensure the actual use effect. In normal use, steel glue is indispensable. However, the actual formula and processing technology of the impregnating glue on the existing market are not scientific, and the actual use effect cannot be guaranteed, resulting in poor performance and poor use effect of the steel glue, and it is impossible to obtain a relatively effective use.

Abstract

The invention relates to sticky steel glue for a bi-component anchor rod. The sticky steel glue is prepared from the following components in parts by mass: a component A: 15-25 parts of liquid polysulfide rubber, 125-135 parts of epoxy resin, 3-5 parts of fumed silica, 2-4 parts of a coupling agent, 10-14 parts of a diluent, 1-3 parts of nano-silicon dioxide and 140-160 parts of quartz powder; a component B: 25-35 parts of amine-terminated polyether, 6-10 parts of m-xylylenediamine, 3-5 parts of maleic anhydride, 1-3 parts of benzyl alcohol and 0.2-0.4 parts of glycerol; and the ratio (parts by mass) of the component A to the component B is 2.5 to 1. The sticky steel glue has the beneficial effects that the formula is reasonable, the processing process is scientific and normative, and theprepared sticky steel glue is extremely high in strength and strong in damp-heat aging resistance and freeze thaw resistance and has very strong adhesive property aiming at waterproof, unclean and oil-carrying surfaces, so that great convenience is brought to the engineering construction.
