New material used for manufacturing light-emitting signboard and manufacturing technology thereof

Abstract

The invention discloses a new material used for manufacturing a light-emitting signboard and a manufacturing technology thereof. The new material is prepared from, 1 kg of PMMA with the molecular weight of 350000-450000 daltons, 180-220 g of an astigmatism agent, 0.6-0.71 g of black powder, 0.281-0.291 g of purple powder, 0.471-0.482 g of blue powder, 18-23 g of a dispersing agent, 19-27 g of a UV agent and 23-28 g of an antistatic agent. The black powder is carbon black powder or nigrosine, the purple powder is permanent purple, or quinacridone or cobalt purple, the blue powder is phthalocyanine blue or vasekine, and an astigmatism agent, black powder, purple powder, blue powder, a dispersing agent, a UV agent, an antistatic agent and PMMA with the defined amount are taken, mixed uniformly, heated at the temperature of 245-255 DEG C for 12-18 min and then cooled to obtain the new material. The component formula of the new material has the advantages of being low in price, easy to prepare and the like.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a new material for making luminous signboards and a manufacturing process thereof. Background technique [0002] Polymethyl methacrylate, polymers obtained by polymerization of acrylic acid and its esters are collectively referred to as acrylic resins, and the corresponding plastics are collectively referred to as polyacrylic plastics, among which polymethyl methacrylate is the most widely used. The abbreviated code name of polymethyl methacrylate is PMMA, commonly known as plexiglass, which is by far the most excellent and relatively affordable variety of synthetic transparent materials. Application: PMMA is soluble in organic solvents, such as phenol, anisole, etc., and can form a good film by spin coating with good dielectric properties. It can be used as an organic field effect transistor (OFET), also known as an organic thin film transistor (OTFT). medium layer. [0...

AI Technical Summary

Problems solved by technology

[0030] 1. The preparation process is relatively complicated, requiring relatively large production and processing sites, and a variety of relatively complicated preparation equipment, the production process is cumbersome, and the production cycle is relatively long

[0031] 2. Due to the complex preparation and many technical difficulties of black and white boards, the price of the product is very expensive, and the actual use cost is relatively high, which is not conducive to popularization and application

[0032] 3. The black and white board is only developed and produced as a general-purpose advertising material. The color is single, which cannot meet the actual needs of colorful advertising signs, and the expressiveness is not rich enough.

[0033] 4. The secondary processing method of black and white board is single. At present, it can only be plastic-absorbed or bonded, which cannot be used in many occasions.
