Abstract
The invention discloses a stabilizer which can stabilize an aziridine three-functional-group room temperature crosslinking agent in water. The stabilizer is prepared by organic amine with R equal to H or organic amine of 1-20 carbon alkyl or 1-20 carbon hydroxyl and buffer solution containing inorganic volatile alkali, wherein, the organic amine is 20pbw (part by weight) to 65pbw and the buffer solution is 80pbw to 35pbw, and the summation of both is 100pbw. The stabilizer is used in the aziridine three-functional-group room temperature cross-linking agent and can ensure that the shelf-life of water paint is 1 year to 2 years; the stabilizer has few components, low cost and can realize single-component water paint of the aziridine three-functional-group room temperature crosslinking agent.
