[0027] The preparation method of the adhesive joint agent can be carried out with reference to the prior art. Preferably, the preparation method of the adhesive joint agent comprises: 1) 80 parts of 10wt% PVA aqueous solution, 8 parts of water glass and 20 parts of water are mixed at 60° C. Mix well; 2) Slowly add 0.2g of TO-7 emulsifier and mix evenly, then add 1.0g of 30wt% citric acid aqueous solution dropwise and mix evenly; 3) Stir and emulsify at 80°C for 20min; 4 ) Finally, mix 4 parts of water glass and 10 parts of water evenly, add slowly drop by drop, and ripen for 24 hours to prepare the adhesive joint agent.
[0028] In the present invention, the DOP plasticizer can make the base treatment agent have a wider temperature application range, specifically, improve the low temperature applicability, and can reduce the construction temperature to below 0°C, and the lowest can reach -5°C. The DOP plasticizer is dioctyl phthalate, referred to as dioctyl phthalate, which is...
