Preparation of urea-formaldehyde resin microcapsule pressure-sensitive adhesive by using in-situ polymerization method

The invention relates to the preparation of a urea-formaldehyde resin microcapsule pressure-sensitive adhesive by using an in-situ polymerization method, which relates to a preparation method of microcapsules. According to the invention, an acrylate pressure-sensitive adhesive as a core material is coated in a microcapsule taking urea-formaldehyde resins as a shell material according to an in-situ polymerization method. According to the invention, an acrylate pressure-sensitive adhesive is coated in a urea-formaldehyde microcapsule firstly, because the materials of the wall of the microcapsule has no adhesiveness, when in use, the pressure-sensitive adhesive can flow out and play roles just through breaking the microcapsule by using a certain external force, and release paper can be omitted, therefore, the purposes of saving raw materials and protecting the environment can be achieved.
