Multi-arm methylol melamine derivative, preparation method and application thereof |
| abstract |
The invention relates to the technical field of thermosetting resin modification, in particular to a preparation method and application of a multi-arm methylol melamine derivative. The hexamethylol melamine is dispersed in an inert diluent, and an organic long-chain modifier is added, The pH of the system is adjusted to 2.5-4.5 with acid, and after reacting at 50-80° C. for 2-12 hours, the pH of the system is adjusted to 7 with alkali, and the inert diluent is recovered by vacuum distillation to obtain a multi-arm methylol melamine derivative. The invention realizes the controllability of the toughness of the melamine resin by controlling the type and content of the added multi-arm methylol melamine derivative, the network crosslinking density of the melamine resin and the size and quantity of the elastic toughening area. The high-toughness melamine material modified by the multi-arm methylol melamine derivative of the present invention has remarkable effect, and its impact strength can be increased by 50～50～ 120%. |
