Toner with good fixing effect in low-temperature environment and preparation process thereof

Abstract

The invention discloses powdered ink with a good fixing effect in a low-temperature environment, and the powdered ink is prepared from the following components in parts by weight: 70 to 95 parts of polyester resin, 1 to 2 parts of low-temperature polyester resin, 1 to 10 parts of pigment, 0.1 to 5 parts of surface modifier, 0.1 to 5 parts of charge control agent and 0.1 to 5 parts of wax. 0.5-5 parts of a charge control agent and 1-10 parts of wax. The invention also discloses a preparation process of the powdered ink with the good fixing effect in the low-temperature environment. Through a surface modification mode, the surface characteristics of the toner are changed, so that the toner can be smoothly fused and fixed in a low-temperature state, and the technical effect of stable handwriting is realized, thereby improving the fixing effect of the existing toner in the low-temperature state.

Description

technical field [0001] The invention relates to the field of preparation and production of toner, more specifically to a toner with good fixing effect in a low temperature environment and a preparation process thereof. Background technique [0002] In the existing laser color copiers, the melted toner is immersed into the printing paper by means of pressurized hot-melt to complete the final fixing. The low temperature environment will make the printer's fusing components unable to reach the working temperature, which will result in poor fusing, prolong the paper output time on the first page, and in severe cases, the toner cartridge sealing material may collapse and leak powder. At present, the mainstream solutions on the market are fixing by using more advanced ceramic heaters (PCT). However, ceramic heaters are a technological product in recent years. Some models are not equipped with ceramic heaters. Therefore, models without ceramic heaters still cannot solve the proble...

Problems solved by technology

However, the ceramic heater is a technological product in recent years, and some models are not equipped with a ceramic heater, so the models without a ceramic heater still cannot solve the problem that the low temperature has a great influence on the fixing effect

The melting temperature of most toners is around 100°C. In order to ensure a good fixing effect, the copier needs to be preheated for 1-2 minutes to make the heating roller reach 185°C, which will obviously affect some urgent printing. users who need
