| titleOfInvention | The preparation method of unsaturated polyester resin mill base vector resin |
| abstract | The present invention discloses the preparation method of a kind of unsaturated polyester resin mill base vector resin, adds dibasic alcohol 70��95 parts, diprotic acid 60��85 parts, MALEIC ANHYDRIDE 18��20 parts in reactor, leads to and also stir evenly into nitrogen in reactor; Heating up gradually makes reactor temperature be 200��220 DEG C, carries out condensation reaction at such a temperature; After question response system becomes homogeneous transparent, insulation continues reaction until recording reaction product acid number to be less than 20mgKOH/g; Described dibasic alcohol is glycol ether or dipropylene glycol, and described polyprotonic acid is hexanodioic acid or SA; The product being obtained by reacting is cooled to 180 DEG C��190 DEG C, in product, then adds Resorcinol 5��6 parts, stir after evenly and material is cooled to less than 40 DEG C, filter and obtain unsaturated polyester resin mill base vector resin. Obtained unsaturated polyester presents good liquid state, is applicable to mill base and uses, and the stability of pigment paste being mixed with is good. |
