| titleOfInvention | A kind of modified water-resistant resin and preparation method thereof |
| abstract | The invention discloses a modified water-resistant resin and a preparation method thereof. The raw material of the modified water-resistant resin is composed of maleic anhydride, isophthalic anhydride, neopentyl glycol, propylene glycol, catalyst, polymerization inhibitor and diluent , the preparation method of the modified water-resistant resin adopts the continuous production and preparation of the resin production reaction system, and the prepared modified water-resistant resin has the advantages of good corrosion resistance to strong acid, good corrosion resistance to strong alkali and good hydrolytic stability; the present invention The preparation method can use nitrogen to purge the feeding device during the process of forming a nitrogen atmosphere in the reactor to avoid residual raw materials in the feeding device, and when the reactor is in a vacuum state, the preparation method does not need to destroy the reactor The raw material can be fed into the interior of the reaction kettle under the vacuum state, and the equal pressure feeding can be realized, and the differential pressure sampling of the material inside the reaction kettle can be realized through the vacuum pump, the pressure regulating pipeline and the sampling device. |
