Problems solved by technology

Existing paint ink solvents are most widely used benzene solvents such as benzene, toluene, and xylene, especially xylene solvents. The mandatory standards for decoration and decoration GB / 18581 and GB / 18582 clearly stipulate the limit value of VOC (volatile organic compounds), benzene, heavy metals, free formaldehyde and other toxic and harmful substances in paint inks, and developed a A new environmentally friendly solvent for paint and ink that is benzene-free and sulfur-free, meets the national paint and ink solvent restriction standards, and can completely replace xylene and other aromatic solvents is an urgent demand in the current paint and ink solvent market
But so far, there is no environmentally friendly solvent that can completely replace aromatic solvents

Abstract

The invention discloses a paint ink solvent and application thereof. The paint ink solvent comprises the following components in percentage by weight: 15 percent to 65 percent of acetic ester, 5 percent to 45 percent of carbonate ester and 15 percent to 70 percent of alkanes. When the paint ink solvent disclosed by the invention is applied in paint, the using amount of the solvent is 20 percent by weight to 50 percent by weight; and when the paint ink solvent disclosed by the invention is applied in ink, the using amount of the solvent is 20 percent by weight to 50 percent by weight. The paint ink solvent provided by the invention is a novel non-benzene and sulfur-free environmental-friendly solvent which accords with the national paint ink solvent restricted standard and can completely replace aromatics solvents such as dimethylbenzene and the like.

Description

technical field [0001] The invention relates to the technical field of paint ink production, in particular to a paint ink solvent. [0002] The present invention also relates to the application of the above-mentioned paint ink solvent. Background technique [0003] The main function of the paint ink solvent is to disperse the film-forming base material to form a viscous liquid, which helps the construction and improves some properties of the coating film. Existing paint ink solvents are most widely used benzene solvents such as benzene, toluene, and xylene, especially xylene solvents. The mandatory standards for decoration and decoration GB / 18581 and GB / 18582 clearly stipulate the limit value of VOC (volatile organic compounds), benzene, heavy metals, free formaldehyde and other toxic and harmful substances in paint inks, and developed a A new type of environmentally friendly solvent for paint and ink that is benzene-free and sulfur-free, meets the national paint and ink s...
