preparation example Construction

[0023] The embodiment of the present invention provides a preparation process of a novel toner, which includes the following steps:

[0024] S1. Prepare toner matrix particles by using binder emulsion, colorant dispersion and release agent dispersion.

[0025] The used binder of preparation toner can use any conventional toner resin, and suitable binder can enumerate and include for example thermoplastic resin and polyester, and thermoplastic resin is usually vinyl resin, especially styrene resin, Suitable thermoplastic resins comprise polymeric esters selected from at least styrene methacrylates, polyolefins, styrene acrylates, cross-linked styrene polymers, epoxies, polyurethanes, vinyl resins, dicarboxylic acids and glycols At least one of the group consisting of compounds.

[0026] The release agent (wax) used to prepare the toner comprises at least one selected from low molecular weight polyethylene wax, maleic anhydride modified polyethylene wax, low molecular weight po...

Embodiment 1

[0063] This embodiment provides a new type of toner MT-2 (i.e. charge regulator spray toner, containing 0.1% charge regulator), which is prepared by using the above components according to the following steps:

[0064] Weigh 100g of toner matrix particles MT-1 and 10g of charge regulator solvent dispersion E1, and spray them onto the surface of the toner matrix particles under the action of micro flash drying equipment, fluidized bed, etc., and the spraying process is at 50-140°C It is carried out at high temperature to form a dry granular material, which is then prepared by removing a good solvent to obtain a new toner MT-2.

Embodiment 2

[0066] This embodiment provides a new type of toner MT-3 (i.e. charge regulator spray toner, containing 1% charge regulator), which is prepared by using the above components according to the following steps:

[0067] Weigh 100g of toner matrix particles MT-1 and 10g of charge regulator solvent dispersion E2, and spray them onto the surface of toner matrix particles under the action of micro flash drying equipment, fluidized bed, etc. It is carried out at high temperature to form a dry granular material, which is then prepared by removing the good solvent to obtain a new toner MT-3.

Abstract

The invention discloses a novel toner and a preparation technology thereof and relates to the field of powdered ink toners. The preparation technology of the novel toner comprises the steps of preparing toner matrix particles from an adhesive emulsion, a colorant dispersion liquid and a release agent dispersion liquid; and dissolving a charge control agent into a good solvent to prepare a charge control agent dispersion liquid and uniformly spraying the charge control agent dispersion liquid on the surfaces of the toner matrix particles. According to the preparation technology, the utilizationlink of the charge control agent is changed, the charge control agent is uniformly sprayed on the surfaces of the toner matrix particles by adopting a spraying mode under the formed state of the toner matrix particles, and the charge control agent is adsorbed on the surfaces of the toner matrix particles in a molecular state, so that the technology is simple and reliable, the prepared toner is good in liquidity, stable in charge distribution, high in environmental adaptability, very low in bottom ash rate and waste toner rate in printing, relatively low in consumption and relatively high in resolution ratio, and the problem that the toner flies and pollutes a machine is effectively solved.

Description

technical field [0001] The invention relates to the field of toner and toner, and in particular to a novel toner and a preparation process thereof. Background technique [0002] With the widespread use of personal computers (PCs) and office automation, the demand for copiers and laser printers continues to grow, and toner is a key consumable for laser printing and digital copying. With the increase of market demand and people's increasingly stringent image quality requirements, higher performance requirements are also put forward for toners. Toner particles need to have a wide charge distribution, excellent charge retention ability, fast charging speed, excellent transferability, low temperature melting ability and anti-bias, etc., the invention and use of charge regulator (CCA) It is to meet the charging performance requirements of the toner particles. [0003] The preparation of toner by physical melting method is to melt the binder, colorant, charge regulator (CCA), rel...
