Abstract

The invention belongs to the technical field of a drawing paint, and particularly discloses a formaldehyde-free art paint and a preparation method thereof. The paint is prepared from gelatin, paint powder, a functional agent, and a corrosion remover formed by BCM (bis-chloromethyl) and chlorothalonil. The formaldehyde-free art paint is prepared by the procedures of gelatin treatment, adding the functional agent, adding the paint powder, adding the corrosion remover formed by BCM and chlorothalonil, and packaging. The formaldehyde-free art paint has the characteristics of being long in quality guarantee period, and effectively preventing aspergillus and penicillium from corroding the drawing in a humid environment.

Description

technical field [0001] The invention belongs to the technical field of painting pigments, and in particular relates to a formaldehyde-free art painting pigment and a preparation method thereof. Background technique [0002] Art painting pigments are composed of pigment powder, vegetable glue and added functional additives including formaldehyde for anticorrosion and humectants, leveling agents, antifreeze agents and anti-cracking agents. The preparation process is as follows: firstly soak and dissolve the vegetable gum, filter, bleach and precipitate; then add formaldehyde and other additives to the precipitated vegetable gum; finally add the pigment powder to the above-mentioned colloid and grind to prepare the painting pigment . There are following defects in the painting pigment prepared by the above-mentioned process: one, the pigment has used formaldehyde as a preservative, because formaldehyde is a kind of volatile toxic substance, not only can the worker's health be ...
