Problems solved by technology

[0002] In the process of home decoration and decoration in the last two decades, in the field of local waterproof sealing, especially in the waterproof sealing of kitchens and bathrooms, most of the silicone sealants are commonly known as glass glue, but glass glue In itself, with the improvement of economic living standards and spiritual and cultural life, its shortcomings are more and more exposed, such as yellowing, blackening, moldy, etc. after long-term use, and it is not resistant to acid and alkali, and has a pungent smell. , low overall strength and easy damage, etc., current research often only solves one of the above problems, such as the patent application number 201210087328.2 which improves the anti-pollution ability of glass glue, and the patent application number 201210265243. The patent application No. 201210067831.1 enhances the anti-mildew function of glass glue, but does not completely solve the many problems existing in the above-mentioned glass glue as a sealing material

Embodiment 1

[0042] The mass composition of each component is as follows:

[0043] A component:

[0044] Epoxy resin R139 60 parts

[0045] Calcium carbonate 15 parts

[0046] Fumed silica 4 parts

[0047] Titanium dioxide 20 parts

[0048] 1 part tributyl citrate

[0049] Component B:,

[0050] 60 parts of N-aminoethylpiperazine

[0051] Calcium carbonate 20 parts

[0052] Fumed silica 4 parts

[0053] Titanium dioxide 15 parts

[0054] 1 part benzyl alcohol

[0055] The production method is to mix and stir the epoxy resin with the brand name R139 and tributyl citrate for 15 minutes, add calcium carbonate and titanium dioxide three times, each interval is 20 minutes, the dispersion speed is 300-500 rpm, add gas phase white Carbon black, disperse and stir for 30 minutes, evacuate for 30 minutes, vacuum degree 0.06-0.09mpa, discharge and pack, this is component A. Mix and stir N-aminoethylpiperazine and benzyl alcohol for 15 minutes, add calcium carbonate and titanium dioxide thr...
