Problems solved by technology

[0003] Conventional water-based dip-coating paints cannot be dip-coated in whole bundles, and they stick to each other when coating, and cannot be well coated into films, slow drying speed, poor adhesion, poor coloring effect, and high viscosity, so they are not suitable for dip-coating construction.

Abstract

The invention discloses a water-borne paint for bundle-shaped dip coating, and a preparation method and a construction process thereof. A formula of the water-borne paint comprises the following raw material components in parts by weight: 35-50 parts of self-crosslinking water-borne resin, 2.5-6.0 parts of a film-forming auxiliary agent, 0.1-0.5 part of a wetting agent, 0.1-0.5 part of a defoamer,0.1-0.5 part of an anti-settling thixotropic agent, 0.6-1.0 part of a thickener and 25.5-49.9 parts of water. Compared with conventional water-borne paints and solvent paints, the water-borne paint for bundle-shaped dip coating allows bamboo sticks not to be adhered with each other after bundle-shaped bamboo sticks are dip-coated with the paint, and has better adhesion force, anti-sedimentation effect, low odor and good coating effect. The water-borne paint for bundle-shaped dip coating can be used for coating construction of a whole bundle of bamboo sticks according to the whole bundle state, can be used for coating and forming at one time, and can save a lot of construction time and site needed for construction.

Description

technical field [0001] The invention relates to a water-based paint composition, in particular to a bundle-shaped dip-coating water-based paint, a preparation method and a construction process thereof. Background technique [0002] As people are increasingly pursuing environmental protection, water-based wood coatings are gradually accepted by the market due to their low-hazard and low-pollution characteristics. Due to the large quantity, strict cost control and high coating efficiency of bamboo stick coating, dip coating has become the best construction method, while oil-based dip coating is increasingly eliminated due to its high VOC and high pollution. [0003] Conventional water-based dip-coating paints are not suitable for dip-coating because they cannot be dip-coated in whole bundles, they stick to each other during coating, they cannot be coated well, have slow drying speed, poor adhesion, poor coloring effect, and high viscosity. Therefore need to develop a kind of ...
