Problems solved by technology

The main disadvantage of existing toner is that the glass transition temperature of the resin used is between 70°C and 75°C, and the softening temperature is between 130°C and 135°C at T1 / 2
Obviously, the softening temperature of the toner is too high: on the one hand, a higher softening temperature will consume a lot of energy. In the context of my country's increasingly prominent environmental problems, it is very necessary to reduce the energy consumed in industrial production; on the other hand , an important parameter of the fixing process of toner on paper is the fixing temperature, and the fixing temperature is closely related to the glass transition temperature and softening temperature of the toner, the glass transition temperature is between 70 ° C and 75 ° C, and the softening temperature is between T1 / 2 The toner between 130°C and 135°C will have problems such as weak fixation and ghosting, and the toner will also damage the printer to a certain extent

[0031] Such as figure 1 As shown, when making the toner of this embodiment, first perform step S1, 100 parts by mass of ethylene glycol phthalate copolymer, 30 parts by mass of styrene butyl acrylate copolymer, 6 parts by mass of phthalate Cyanine blue, phthalocyanine red in 4 parts by mass, polypropylene wax in 4 parts by mass and charge control agent in 2 parts by mass, a total of 6 kinds of materials were put into the Henschel high-speed mixer and mixed to obtain the first mixture. The high-speed mixer The rotating speed is 950rpm, and the time is 5 minutes.

[0032] Then step S2 is executed, the first mixture is melt-kneaded and extruded into the second mixture through a twin-screw extruder, the melt temperature of the melt-kneading is controlled at 100° C., and step S2 is repeated once.

[0033] Then step S3 is executed, the second mixture is rapidly cooled by a blower, and crushed by a hammer crusher to obtain a third mixture with a particle size of 0.1 mm to 1 mm.

[0038] When making the toner of the present embodiment, first, 100 parts by mass of polyester resin, 25 parts by mass of styrene acrylic resin, 9 parts by mass of phthalocyanine blue, 1 part by mass of phthalocyanine red, 4 parts by mass of polypropylene The wax and 2 parts by mass of the charge control agent were put into a Henschel high-speed mixer and mixed to obtain the first mixture at a rotation speed of 950 rpm for 5 minutes.

[0039] Then, the first mixture is melt-kneaded and extruded into the second mixture through a twin-screw extruder, and the process of melt-kneading and extrusion by the twin-screw extruder needs to be repeated once, and the melt temperature of the melt-kneading is controlled at 150°C . After the second mixture is rapidly cooled by a blower, it is crushed by a hammer crusher to obtain a third mixture with a particle size of 0.1 mm to 1 mm.

[0040] The third mixture was further pulverized by a jet mill to obtain basic particles with an average pa...

[0043] When making the toner of the present embodiment, the polyester resin of 100 mass parts, the styrene acrylic resin of 14 mass parts, the phthalocyanine blue of 4 mass parts, the phthalocyanine red of 0.5 mass parts, the polypropylene wax of 4 mass parts and 2 parts by mass of the charge control agent were put into a Henschel high-speed mixer and mixed to obtain the first mixture at a rotation speed of 950 rpm for 5 minutes.

[0044] The first mixture is melted and kneaded by the twin-screw extruder to be extruded into the second mixture, and the process of the twin-screw extruder to perform the melt kneading and extrusion needs to be repeated once, and the melt temperature of the melt kneading is controlled at 110°C. After the second mixture is rapidly cooled by a blower, it is crushed by a hammer crusher to obtain a third mixture with a particle size of 0.1 mm to 1 mm.

Abstract

The invention provides powdered ink for a laser blueprint machine. The powdered ink consists of the following components in percentage by weight: 60-80 percent of a polyester resin, 10-30 percent of a styrene acrylic acid resin, 1-10 percent of phthalocyanine blue, 0.1-4 percent of phthalocyanine red, 2-5 percent of a release agent and 1-3 percent of a charge control agent. The glass transition temperature Tg of the polyester resin is 40-55 DEG C, and the softening temperature T1/2 of the polyester resin is 80-110 DEG C; and the glass transition temperature Tg of the styrene acrylic acid resin is 50-70 DEG C, and the softening temperature T1/2 of the styrene acrylic acid resin is 120-140 DEG C. The powdered ink provided by the invention is excellent in performance, firm in fixation and double image-free in the fixation process, the fixation temperature is low, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to a printing material for a laser blueprint machine, in particular to a toner for a laser blueprint machine modified by polyester resin and a manufacturing method. Background technique [0002] Blueprints are widely used in R&D and design work in the fields of machinery and architecture. Blueprint drawings have the advantage of a long storage time during the storage of files, and can prevent illegal modification of drawings. [0003] The traditional blueprint manufacturing process is to first print the black sulfuric acid map with an engineering machine, and then use a printing machine to print the blueprint. This method is not only low in efficiency, but also high in cost. At the same time, because ammonia water is used when printing blueprints, it will pollute the environment and endanger the health of operating workers. The manufacturing process of traditional blueprints involves many drawing steps, which is easy to cause was...
