Problems solved by technology
The invention provides a pre-reaction liquid for a chlorinated rubber adhesive and a preparation method thereof.The pre-reaction liquid is prepared through the following steps: magnesium nitrate and aluminum nitrate are used for preparing magnesium-aluminum hydrotalcite, then a layered-embedded hydrotalcite-sodium phenolate compound is prepared, the hydrotalcite-sodium phenolate compound firstly coats the surfaces of magnesium oxide particles, then, high-molecular-weight p-tert-butylphenol formaldehyde resin can be adsorbed on the surfaces of the magnesium oxide particles, so that the magnesium oxide particles in the pre-reaction liquid suspend in the solution and are not easy to agglomerate to form precipitates, and the solid-liquid layering phenomenon of the pre-reaction liquid is prevented. The prepared pre-reaction liquid can be applied to preparation of an adhesive for chlorinated rubber, the adhesive force, heat resistance and storage stability of the adhesive are improved, and the pre-reaction liquid is easy to prepare and suitable for popularization and application.
