Abstract: The present disclosure discloses a high-temperature fast-curing starch-based adhesive for particleboards and a preparation method thereof, belonging to the technical field of adhesive preparation. The low viscosity of the starch-based adhesive is ensured by selecting a crosslinking monomer which does not self-crosslink in a reaction process in the present disclosure, and a binary crosslinking agent matched with the crosslinking monomer is added before use to be quickly crosslinked with the crosslinking monomer at high temperature so as to ensure better thermosetting property and water resistance as well as faster curing speed of the starch-based adhesive at the same time, which meets the requirements of the particleboards for the adhesive, solves the problem of long curing time of the existing starch-based adhesives at high temperatures, further shortens the curing time of the starch-based adhesives to about 60 s, and improves the production efficiency of the particleboards.

Abstract: The present disclosure discloses an automatic trash bag sealing device for an automatic cat litter box and an automatic cat litter box. In the automatic trash bag sealing device, a drive motor drives a first rod and/or a second rod to rotate, thereby driving a pushing member to move towards a sealing member, and the trash bag is sealed when the sealing member is interfaced with the pushing member. The sealing device has fewer parts and is simple to assemble, effectively reducing the difficulty of process assembly and the overall cost of the automatic cat litter box.
