【Abstract】 The author synthesized melamine-formaldehyde resin from melamine and formaldehyde as raw material and then blended the resultant homogeneously with emulsifier,blowing agent and catalyst to prepare the target product-soft melamine-formaldehyde foam.The effects of the microwave radiation power and the radiation time on foaming were examined.The mechanical properties,thermal properties,resistance to chemical causticity and acoustic properties of the melamine-formaldehyde foam were tested.The results reveal that microwave radiation is a high efficient and convenient method to prepare the melamine-formaldehyde foam.更多还原
