Abstract

The invention discloses a water-based anti-sagging clear primer and a preparation method thereof, and the water-based anti-sagging clear primer comprises the following components in parts by weight: 70 to 85 parts of a water-based polyurethane emulsion, 2 to 5 parts of a coalescing agent, 0.1 to 0.4 part of a wetting agent, 0.4 to 1 part of a defoaming agent, 2 to 4 parts of a polishing aid, 5 to 18 parts of water and 0.5 to 2 parts of associated polyether polyurethane. The preparation method is simple and feasible, and the prepared clear primer does not generate a rib expansion phenomenon when being coated on a wood board, is safe and environment-friendly, has efficient sealing performance and can solve the problem of spraying sagging of a vertical surface.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based anti-sagging clear primer and a preparation method thereof. Background technique [0002] With the continuous increase of people's awareness of environmental protection and health, the environmental protection laws of various countries have gradually become stricter on VOC restrictions. As a major VOC emitter, furniture manufacturers have become the target of public criticism, which has also brought great challenges to the development of water-based coatings. Opportunity, water-based wood paint as an environmentally friendly product needs to be promoted vigorously, but as a young member of the paint family, water-based paint still needs to be gradually improved and perfected in many properties. Its drying speed is not as fast as solvent-based products, resulting in low production efficiency. Can not meet the high efficiency requirements of the factory. By improvin...
