| titleOfInvention | Prepare the method for melamine/formaldehyde foam |
| abstract | The present invention relates to prepare the method for melamine/formaldehyde foam, it comprises following methods step: the aqueous mixture M1 that a) preparation comprises following material): at least one melamine/formaldehyde precondensate of 100 weight portions, at least one curing agent of 2 to 4 weight portions, the surfactant mixture of 0.2 to 5 weight portion, at least one inorganic acid salt or the organic carboxylate of 0.1 to 5 weight portion, at least one blowing agent of 1 to 40 weight portion, at least one colouring agent and/or the fluorescent whitening agent of 0 to 5 weight portion, one or more other additives of 0 to 20 weight portion, and the water of 25 to 60 weight portions, b) use carry out microwave radiation heating and the described mixture M 1 of foaming), c) use curing agent and microwave that established foam is crosslinked and curing, d) use the dry described foam of microwave, and e) use hot-air to the annealing of dry foam. according to the present invention, described mixture M 1) must contain the mixture being formed by the anion surfactant of 50 to 90 % by weight and the non-ionic surface active agent of 10 to 50 % by weight as surfactant mixture, these percentage by weights are separately in the gross weight of surfactant mixture. the invention still further relates to melamine-formaldehyde foam of preparing by the inventive method and uses thereof. |
