Title:
ENVIRONMENTALLY FRIENDLY WATER-BASED COATING AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/007425
Kind Code:
A1
Abstract:
Disclosed are an environmentally friendly water-based coating and a preparation method therefor. The water-based coating comprises 30.0 to 45.0 parts by weight of water-based acrylic monodisperse resin and 20.0 to 40.0 parts by weight of water-based styrene-acrylic resin as main connecting materials, and in addition, 0.3 to 1.0 part by weight of a rheological additive, 0.5 to 1.5 parts by weight of a wetting agent A, and 0.1 to 0.5 parts by weight of a wetting agent B, and does not include a low-boiling-point organic solvent, wherein said rheological additive is an associative polyether polyurethane, said wetting agent A is an ethoxy modified alkyne diol substrate wetting agent, and said wetting agent B is a polyether modified organic silicon wetting agent. The environmentally friendly water-based coating of the present invention does not require the use of an emulsifier in the preparation process, has good water solubility, and does not need to increase water solubility by adjusting the pH value by means of adding aqueous ammonia, organic amines, etc. The product thus remains neutral, thereby ensuring the product being environmentally friendly, and reducing the use of amines and emulsifiers.
