Abstract

The invention relates to a preparation method of environment-friendly paint. The environment-friendly paint is prepared from the following raw materials in parts by weight: 20 to 32 parts of water-borne resin, 2 to 5 parts of dye additives, 40 to 65 parts of water, 0.3 part of LT rheological additives, 0.5 to 0.7 part of WT-204 rheological additive and 3 to 5 parts of film forming additives; the raw materials in parts by weight are weighed and taken; water is transferred into a reaction vessel; the temperature is controlled to be 40 to 50 DEG C; the water-borne alkyd resin is added while stirring is performed; the temperature is controlled to be 50 to 60 DEG C; then, water-borne polyurethane resin emulsion is added while the stirring is performed; the LT rheological additives, the WT-204 rheological additives, the film forming additives and the dye additives are sequentially added while the stirring is performed; after the stirring, the mixture is enabled to stand. The preparation method of the environment-friendly paint has the advantages that the operation and the control are convenient; the energy consumption is small; the popularization is facilitated.

Description

technical field [0001] The invention relates to a paint technology, in particular to a preparation method of an environmentally friendly paint.
