the modified glass beads are coated with coupling agents on the surfaces.

By adopting the technical scheme, the brightening metal powder and the modified glass beads are added in the high-finish ABS plastic powder box spray paint, and are reflective materials, wherein the glass beads have better dispersibility after being modified by the coupling agent, can be uniformly dispersed in a mixed solution of acrylic resin and a solvent under the action of a dispersing agent and an antioxidant, and are matched with the brightening metal powder, so that the capacity of reflecting external light rays of the spray paint is improved, and a paint film layer with fine color, high brightness and high finish is formed after the spray paint is sprayed. Meanwhile, the modified glass beads in the formula are also used as fillers, are light in weight and high in structural strength, and can be uniformly dispersed in acrylic resin after being modified, so that the collapse resistance and the wear resistance of the spray paint are ensured, the surface of a paint film is smooth, and the structure is more stable.

Further, the acrylic resin includes a thermoplastic acrylic resin and a thermosetting acrylic resin.

By adopting the technical scheme, the thermoplastic acrylic resin has larger relative molecular weight, good gloss retention, color retention, water resistance and chemical resistance, the thermosetting acrylic resin has lower relative molecular weight and can react with the amino resin to form a net structure, so that the spray paint has higher gloss, hardness, solvent resistance and weather resistance, and after the thermoplastic acrylic resin and the thermosetting acrylic resin are combined, the spray paint can form a paint film with good adhesion after being sprayed on the surface of the ABS plastic powder box.

Further, the brightening metal powder is one or more of silver powder, copper powder and aluminum powder.

By adopting the technical scheme, the brightening metal powder is a reflective material and is uniformly added into the acrylic resin, so that the reflective capability and the structural strength of the prepared spray paint can be obviously improved, and a paint film formed by the paint can be smooth and flat. In addition, the brightening metal powder in the formula is preferably one or more of silver powder, copper powder and aluminum powder, the three kinds of metal powder filled in the paint vehicle are light in weight, an oxide film layer is formed on the surface of the metal powder, and the three kinds of metal powder can be uniformly distributed with the modified glass beads in the formula system, stably exist and are not easy to react with other components. The smaller the particle size of the copper powder is, the weaker the metal feeling is, the higher the covering power is, and the softer the color of the formed paint film layer is; the silver powder and the aluminum powder are in a white and bright powder shape, the surface is smooth and flat after processing, and the reflectivity to visible light, infrared light and ultraviolet light with the wavelength of 280 plus 400nm reaches 60-90%.

Further, the dispersant is any one of dispersant AM-C, dispersant DC and dispersant DA.

By adopting the technical scheme, the dispersing agent is used as a surfactant with two opposite properties of lipophilicity and hydrophilicity in a molecule, so that the pigment filler, the brightening metal powder and the modified glass beads can be uniformly dispersed in a mixed solution of acrylic resin and a solvent, and meanwhile, the pigment filler, the brightening metal powder and the modified glass bead particles can be effectively prevented from settling and coagulating. Any one of a dispersant AM-C, a dispersant DC and a dispersant DA is selected as the dispersant in the formula, and the three dispersants are generally applied to production and processing of paint vehicles, so that the paint vehicle has stable performance and strong practicability.

Moreover, the arrangement also enables the slurry sprayed by the paint spraying device to be finer and more delicate and denser, and enables a paint film formed after drying to be smoother and smoother.

Further, the coupling agent is a silane coupling agent.

By adopting the technical scheme, the silane coupling agent is used as the surface modifier, so that the interface performance between the glass beads and the acrylic resin can be improved, the viscosity of acrylic resin melt is reduced, the dispersion degree of the glass beads in the acrylic resin is improved, and the coating paste is more uniform and stable.
