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., the current research often only solves one of the above problems, such as the patent application number 201210087328. The patent application No. 201210067831.1 enhances the anti-mildew effect of glass glue, but the existing technology has not completely solved the many problems of the above-mentioned glass glue as a sealant

Embodiment 1

[0039] The mass composition of each component in this embodiment is as follows: A component: 80 parts of epoxy resin R139, 3 parts of calcium carbonate as an inorganic filler, 3 parts of thixotropic agent fumed silica, 5 parts of diluent benzyl alcohol, functional auxiliary 3 parts of nano titanium dioxide; Component B: 40 parts of curing agent J-3217, 2 parts of inorganic filler calcium carbonate, 1 part of thixotropic agent fumed silica, and 1 part of diluent benzyl alcohol. Mix and stir the epoxy resin of R139 and benzyl alcohol for 15 minutes, and drop in calcium carbonate and nano-titanium dioxide three times according to Table 1, with an interval of 20 minutes each time. The dispersion speed is 300-500 rpm. Add fumed white carbon black according to the amount in Table 1, disperse and stir for 30 minutes, and pump it out for 30 minutes and then package it as component A. Mix and stir curing agent J-3217 and benzyl alcohol according to the amount in Table 1 for 15 minutes...

Embodiment 2

[0042] The mass composition of each component in this embodiment is as follows: Component A: 82 parts of epoxy resin R140, 5 parts of barium sulfate as an inorganic filler, 4 parts of thixotropic agent fumed silica, 6 parts of diluent acetone, functional auxiliary agent 4 parts of nano titanium dioxide; B component: 41 parts of curing agent J-3216, 3 parts of inorganic filler barium sulfate, 2 parts of thixotropic agent gas phase white carbon black, no diluent added. Repeat the method of embodiment 1, but in A component, replace the epoxy resin of R139 with the epoxy resin of R140, replace calcium carbonate with barium sulfate, replace benzyl alcohol with acetone; Agent J-3216 replaces J-3217, replaces calcium carbonate with barium sulfate, and does not use diluent.

[0043] Then test the various properties of the product, the test results are as follows: delicate appearance, dark white, average glaze, shear strength 12.3MPa, sag 0mm, surface dry time 25min, hardness 90, easy ...

Embodiment 3

[0045] The mass composition of each component in this embodiment is as follows: Component A: 84 parts of epoxy resin R142, 6 parts of aluminum oxide as an inorganic filler, 5 parts of fumed silica as a thixotropic agent, 7 parts of anhydrous ethanol as a diluent, functional type Auxiliary nano-titanium dioxide 5 parts; B component: curing agent J-3216 42 parts, inorganic filler alumina 4 parts, thixotropic agent fumed silica 3 parts, diluent acetone 2 parts. Repeat the method of embodiment 1, but in A component, replace the epoxy resin of R139 with the epoxy resin of R142 brand, replace calcium carbonate with aluminum oxide, replace benzyl alcohol with dehydrated alcohol; In B component Replace J-3217 with curing agent J-3216, replace calcium carbonate with alumina, and replace benzyl alcohol with acetone.

[0046] Then test the various properties of the product, the test results are as follows: delicate appearance, dark white, average glaze, shear strength 11.8MPa, sag 0mm, s...
