Embodiment 1
[0012] An adhesive is provided in an embodiment of the present invention, comprising the following components in parts by weight, 2-6 parts of unsaturated resin, 6-10 parts of calcium powder, 0.0006-0.001 part of cobalt water, and 0.0006-0.001 part of curing agent part and 0.1-0.4 part of styrene, more preferably, including 4 parts of unsaturated resin, 8 parts of calcium powder, 0.00084 part of cobalt water, 0.000912 part of curing agent and 0.2 part of styrene.
[0013] Concrete, the choice of unsaturated resin can be various, as unsaturated resin can be 168 resin, 399 resin or 6688 resin, above-mentioned resin all is unsaturated resin, after it is mixed with curing agent and accelerator, It is easier to achieve curing, and the bonding effect is good, especially suitable for bonding glass products. In addition, white water is the preferred curing agent. Because white water has low price and good performance, it is easy to mix with resin and is extremely convenient to use.

Embodiment 2
[0019] This embodiment provides a preparation method corresponding to the adhesive provided in the above embodiments, which specifically includes the following steps:
[0020] Step 101: adding cobalt water into the unsaturated resin and stirring to obtain a first solution;
[0021] In step 101, after the cobalt water is added to the unsaturated resin, the first solution is obtained. Specifically, in order to make the cobalt water mix uniformly during the process of adding the unsaturated resin, preferably, the cobalt water is added to the unsaturated resin. During the process, the unsaturated resin is stirred and mixed at the same time, so that the effect of mixing can be achieved.
[0022] Step 102: adding calcium powder into the first solution and stirring to obtain a second solution;
[0023] After obtaining the first solution, it is necessary to add the calcium powder to the first solution. Preferably, in order to make the calcium powder mix with the first solution at a f...
Embodiment 3
[0036] Add 8ml of cobalt water (about 8.4g) to 40kg of 168 unsaturated resin and stir to obtain the first solution; at a temperature of 20°C-28°C, add 80kg of calcium powder to the first solution, and stirred to obtain the second solution; 2 kg of styrene was added to the second solution to obtain the third solution; 8 ml (about 9.12 g) of curing agent was added at a temperature of 20°C-28°C After entering the third solution, stir for 25 minutes to 30 minutes and add to the third solution to obtain an adhesive.
[0037] The adhesive prepared through the steps of Example 3 is experimentally determined to be less likely to soften under the use condition of 60°C.
[0038] In addition, for the adhesive prepared by the preparation method of the above example, since the ratio of the components of the adhesive is optimized, the adhesive is applied to the bonding process, and the bonded board has High toughness, not easy to peel off, crack resistance, corrosion resistance and stampin...
