Abstract

The invention discloses a novel environment-friendly cleaning agent as well as a preparation method and an application thereof. The novel environment-friendly cleaning agent is prepared from the following raw materials in parts by weight: 5-30% of a low-molecular-weight solvent oil, 20-50% of medium-molecular-weight solvent oil, 2-20% of medium-high-molecular-weight solvent oil, 0.5-10% of a low-molecular-weight solvent, 0.1-2% of a nonionic surfactant, 0.1-5% of a cationic surfactant, 0.1-5% of an anionic surfactant, 0.02-0.2% of essence, and balance of water. According to the invention, different types of surfactants are added, and the organic solvent is dispersed in water in the form of small droplets, so that the discharge of the organic solvent is reduced. During cleaning, the structure of liquid drops distributed in water is destroyed, and the organic solvent separates out contact stains, so that the cleaning effect is achieved. When the cleaning is finished and is in a static state, the mixed droplet structure is formed again, and the organic solvent is hooped in the water of a dispersion medium to prevent volatilization and emission of the solvent.

Description

technical field [0001] The invention belongs to the technical field of printing oil stain cleaning, and in particular relates to a novel environment-friendly cleaning agent and its preparation method and application. Background technique [0002] At present, in the printing production process, when cleaning the ink roller or rubber, the most commonly used cleaning agent is the Lisu cleaning agent in the Sai Feiyang series products produced by Heidelberg. There are also different degrees of component modifications based on this cleaning agent. The product. Its main components are various types of solvent oils, from No. 6, No. 70, and No. 90 to No. 120, No. 180, No. 200, and No. 260 solvent oils, and some products are added with No. 100 and No. 150 solvent oils; No. 100 and No. 150 are mainly composed of aromatic hydrocarbons; the rest are mainly composed of alkanes. Due to different production methods and sources, even alkane solvent oils will contain a considerable amount ...
