METHOD OF APPLYING AN ADHESIVE FILM
In a method for applying an adhesive film (10) to the surface (20) of a component, an adhesive film (10) including an adhesive layer (11) is provided. Furthermore, a component including a surface (20) to which the adhesive film is to be applied is provided. A physical surface activation of the adhesive layer (11) of the adhesive film (10) is carried out. The adhesive layer (11) of the adhesive film (10) is moistened before the surface-activated and moistened adhesive film (10) is brought in contact with the surface (20) of the component to which the adhesive film is to be applied.
Low-viscosity thermosetting starch adhesive for particleboards, and preparation method therefore
The present disclosure discloses a low-viscosity thermosetting starch adhesive for particleboards, and a preparation method therefore, belonging to the technical field of adhesive preparation. The adhesive of the present invention selects N-hydroxyethyl acrylamide or acetoxyethyl methacrylate as the crosslinking monomer, which has a low degree of crosslinking in the process of adhesive preparation to avoid the problem of increasing viscosity, but can cross-link quickly during the hot pressing process, forming a network structure, and improving the water resistance of the adhesive; and furthermore, itaconic acid is added to promote the self-crosslinking reaction of the crosslinking monomer in the hot-pressing process, thus further improving the water resistance. The properties of the manufactured particleboards reach the standard of P2 type particleboards, so that the adhesive can be suitable for mass production and can be widely applied in the preparation of wood decoration, particleboards, plywood and fiberboard.
RF cured nanocomposite adhesives for multi-material joining applications
A method for fabricating, and curing, nanocomposite adhesives including introducing nanoheater elements into a heat-curing adhesive to fabricate a nanocomposite adhesive, and providing a radio-frequency (RF) electromagnetic wave to the nanocomposite adhesive to heat, and cure the nanocomposite adhesive. The nanocomposite adhesive is physically applied to first and second materials to bond the first and second materials upon curing of the nanocomposite adhesive, and the RF electromagnetic wave has a frequency in the radio-frequency range, having energy that is transferred to the nanoheater elements by electromagnetic wave interactions with permanent and induced dipoles, intrinsic photon-phonon interaction, or interactions with nanoheater defects and grain structures.
