摘要（英）：

The invention relates to a preparation method of a cross-linking agent and in particular relates to a preparation method of a rubber adhesive HMMM (Hexamethoxy Methyl Melamine). After water reacts with paraformaldehyde, methanol is added, and a technological process of etherifying, neutralizing and distilling is carried out. According to the preparation method of the cross-linking agent, an inorganic acid is used as a catalyst and can be used for completely neutralizing; an intermediate product is not generated and the purity of the product is kept.
