Description

Technical Field

[0001] The invention relates to the technical field of melamine adhesive processing, in particular to a modified melamine adhesive and a preparation method thereof. Background Art

[0002] Melamine adhesive is a thermosetting resin adhesive, mainly produced by the polycondensation reaction of melamine and formaldehyde to form melamine formaldehyde resin (MF resin). It is known for its excellent heat resistance, water resistance and chemical resistance, and is suitable for bonding a variety of materials, such as wood, paper, metal and plastic. Melamine adhesive has the characteristics of high hardness, wear resistance and fast curing, and is widely used in furniture manufacturing, building materials, decorative panels and molded products. Acrylic emulsion is a water-based polymer emulsion, which is polymerized from acrylic acid and its ester monomers. It is widely used in coatings, adhesives, textile processing and building materials. Acrylic emulsion is added to melamine resin as a modified material, which can provide better flexibility and bonding performance. Acrylic emulsion is usually stable at room temperature and easy to stir and mix. In the prior art, during the preparation of modified melamine adhesives, residual materials from the previous batch may react with new batches of materials, thereby interfering with the chemical reaction of the new batches of materials, resulting in incomplete reactions or side reactions, such as changes in viscosity, prolonged or shortened curing time, reduced bonding strength, etc., leading to unstable product quality. Therefore, the preparation of modified melamine adhesives needs to be carried out under the condition that the inside of the reaction device is completely clean. The existing cleaning method takes a long time, which will extend the production cycle and reduce production efficiency. Summary of the invention
