Description
Technical Field
The invention relates to a decorative material, in particular to a processing method of a board special for luminous characters.
Background
The panel used by the luminous characters in the current market is acrylic, the toughness problem of single GPPS caused by the components of the panel in practical use has a plurality of defects, the production cost is increased, the service life is short, the color is not bright and uniform enough, and the aesthetic feeling is influenced. The traditional acrylic plate is easy to yellow and weather in the sun, and the surface brightness and hardness are different, so that the traditional acrylic plate is easy to scratch by foreign matters.
Therefore, a processing method for a special plate for light-emitting characters is imperative.
Disclosure of Invention
The invention aims to solve the technical problems that the existing acrylic plate has a plurality of defects in practical use, so that the problems of poor use effect, low user satisfaction degree and the like are caused, the production benefit of manufacturers is further influenced, and the current requirements are not met.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: a processing method of a board special for luminous characters comprises the following steps:
s1, mixing 85% of GPPS (general purpose polystyrene) particles and 15% of HIPS (high impact polystyrene) particles, adding the toner, the light diffusion powder, the antioxidant and the anti-violet auxiliary agent, and uniformly stirring by a stirrer;
s2, pouring the stirred material obtained in the step S1 into a feed inlet of a screw extruder, and extruding the material after high-temperature plasticization;
s3, extruding the material extruded in the step S2 into plates with various thicknesses through a die layer of a die;
s4, flattening and calendaring the formed plate in the step S3 by three mirror rollers, and then carrying out UV spraying and ultraviolet drying treatment;
and S5, pressing the protective film on the two sides of the plate processed in the step S4 through a press roll, and finally cutting and sawing the plate into a standard size through a plate sawing machine.
Compared with the prior art, the invention has the advantages that: GPPS granules and HIPS granules are selected, so that the toughness problem of single GPPS is solved, organic toner and light diffusion powder are added, so that the plate obtained by the GPPS through an extrusion process has various colors, and the color of light is brighter and more uniform than that of acrylic; the problems of yellowing and weathering of the attribute of GPPS in sunlight are solved by the added antioxidant and anti-aging agent; the surface is directly dried by spraying UV through a spray mist and an ultraviolet lamp, so that the brightness and hardness of the surface are increased, and the surface is less prone to scratching; the surface of the plate is uniform and bright in color.
Detailed Description
When the invention is implemented, the processing method of the special board for the luminous characters comprises the following steps:
s1, mixing 85% of GPPS (general purpose polystyrene) particles and 15% of HIPS (high impact polystyrene) particles, adding the toner, the light diffusion powder, the antioxidant and the anti-violet auxiliary agent, and uniformly stirring by a stirrer;
s2, pouring the stirred material obtained in the step S1 into a feed inlet of a screw extruder, and extruding the material after high-temperature plasticization;
s3, extruding the material extruded in the step S2 into plates with various thicknesses through a die layer of a die;
s4, flattening and calendaring the formed plate in the S3 step by three mirror rollers, and then carrying out UV spraying and ultraviolet drying treatment;
and S5, pressing the protective film on the two sides of the plate processed in the step S4 through a press roll, and finally cutting and sawing the plate into a standard size through a plate sawing machine.
The working principle of the invention is as follows: the processing method comprises the steps of selecting 85 mass percent of GPPS (general purpose polystyrene) granules and 15 mass percent of HIPS (high impact polystyrene) granules, adding toner, light diffusion powder, an antioxidant and an anti-ultraviolet assistant, uniformly stirring the mixture by a stirrer, pouring the mixture into a feed inlet of a screw extruder, plasticizing the mixture at high temperature, extruding the mixture, extruding plates with various thicknesses through a die layer of a die, rolling and flattening the plates by three mirrors, carrying out press polishing treatment, carrying out UV (ultraviolet) spraying and ultraviolet drying treatment, pressing protective films on two sides by a press roller, and cutting and sawing the plates to a standard size by a plate sawing machine.
On the formed plate, the added materials are GPPS granules and HIPS granules, the toughness problem of single GPPS is solved, organic toner and light diffusion powder are added, the plate obtained by the GPPS through the extrusion process has various colors, and the color of light is brighter and more uniform than that of acrylic.
And the antioxidant and the anti-aging agent are added, so that the problems of yellowing and weathering of the attribute of the GPPS in the sunlight are solved.
The surface is directly dried by spraying UV through a spray mist and an ultraviolet lamp, so that the brightness and hardness of the surface are increased, and the surface is less prone to scratching.
The surface of the formed plate is uniform and bright in color.
