This application provides a glue-applying robot, comprising: a vehicle body; a glue-applying mechanism connected to the vehicle body; and multiple wheels connected to the underside of the vehicle body. Each wheel is equipped with an individual lifting mechanism, which is vertically connected to the vehicle body to drive the wheel to move up and down relative to the vehicle body. In this application, the glue-applying robot can perform glue-applying operations at different heights, greatly expanding its applicable scenarios. Furthermore, the robot enables rapid movement across corrugated ribs, significantly reducing the workload of the operator and improving the glue-applying efficiency.

The invention provides a universal surfactant and a preparation method thereof.The preparation method of the universal surfactant comprises the following steps that S1, a titanate cross-linking agent and a silane coupling agent are mixed and stirred, and a first mixture is obtained; s2, adding a hydrocarbon solvent into the first mixture, and stirring to obtain a turbid second mixture; s3, adding an alcohol solvent into the second mixture, and stirring to obtain a clarified third mixture; and S4, adding a catalyst into the third mixture, and stirring to obtain the universal surfactant. The universal surfactant is non-corrosive, has wide applicability to various base materials and adhesives, can effectively improve the bonding performance of low-surface-energy base materials, and integrates the polyurethane adhesive and the silica gel, and the preparation method is simple, stable and controllable, clear in process index and convenient for industrial large-scale production and popularization.

The invention belongs to the field of adhesives, and provides PMMA (polymethyl methacrylate) glue with viscosity regulated and controlled by glacial acetic acid and a preparation method of the PMMA glue. According to the invention, a dual design of synergistic viscosity reduction of a PMMA matrix and free glacial acetic acid and slow release regulation and control of the PMMA-coated glacial acetic acid microcapsule is adopted, accurate regulation and control of the viscosity in a range of 500-50000 mPa.s are realized by controlling the dosage of glacial acetic acid in a range of 2-15 parts by mass, and meanwhile, the microcapsule component gradually releases glacial acetic acid in a glue drying process, so that the viscosity of the microcapsule is reduced, and the viscosity of the microcapsule is reduced. The viscosity rise caused by solvent volatilization is compensated, low viscosity, easy construction and high cohesion strength after drying are guaranteed, the problems that the construction performance and curing strength of traditional PMMA glue are difficult to balance, a high-solid-content system is difficult to defoam, and the storage viscosity stability is poor are solved, and the PMMA glue has wide industrial application value.
