Embodiment 1

[0028] Such as figure 1 As shown, after accurately weighing 80 parts of water-based resin, put it into the disperser at one time, use deionized water as solvent, and the water-based resin is water-based anionic emulsion resin (Y195); mix 3 parts of film-forming aid A with 4 parts of film-forming aid After B is uniformly mixed, control the disperser to slowly drop film-forming aid A and film-forming aid B under the dispersion state of 1000r / min, and disperse at a high speed for 15 minutes. Film-forming aid A is Dow dipropylene glycol propyl ether (DPNP ), film-forming aid B is Dow dipropylene glycol methyl ether (DPM); control the disperser at 800r / min, slowly add 1 part of wetting agent dropwise, the wetting agent is polyether trisiloxane (8030), disperse 10 minutes; slowly drop 5 parts of dispersant, the dispersant is block copolymer and wet silicone (7117), disperse for 15 minutes; slowly add 0.2 parts of defoamer, disperse for 10 minutes, the defoamer is poly Ether siloxan...

Embodiment 2

[0030] Such as figure 1 As shown, after accurately weighing 85 parts of water-based resin, put it into the disperser at one time, use deionized water as solvent, and the water-based resin is water-based anionic emulsion resin (Y195); mix 6 parts of film-forming aid A with 2 parts of film-forming aid After B is uniformly mixed, control the disperser to slowly drop film-forming aid A and film-forming aid B under the dispersion state of 1200r / min, and disperse at a high speed for 20 minutes. Film-forming aid A is Dow dipropylene glycol propyl ether (DPNP ), film-forming aid B is Dow dipropylene glycol methyl ether (DPM); control the disperser at 1000r / min, slowly add 1.6 parts of wetting agent dropwise, the wetting agent is polyether trisiloxane (8030), disperse 15 minutes; slowly add 3 parts of dispersant, the dispersant is block copolymer and wet silicone (7117), disperse for 10 minutes; slowly add 1 part of defoamer, disperse for 15 minutes, the defoamer is polymer Ether silo...

Embodiment 3

[0032] Such as figure 1 As shown, after accurately weighing 100 parts of water-based resin, put it into the disperser at one time, use deionized water as solvent, and the water-based resin is water-based anionic emulsion resin (Y195); mix 4 parts of film-forming aid A with 2 parts of film-forming aid After B is uniformly mixed, control the disperser to slowly drop film-forming aid A and film-forming aid B under the dispersion state of 1100r / min, and disperse at a high speed for 18 minutes. Film-forming aid A is Dow dipropylene glycol propyl ether (DPNP ), film-forming aid B is Dow dipropylene glycol methyl ether (DPM); control the disperser at 900r / min, slowly add 2 parts of wetting agent dropwise, the wetting agent is polyether trisiloxane (8030), disperse 13 minutes; slowly add 4 parts of dispersant, the dispersant is block copolymer and wet silicone (7117), disperse for 13 minutes; slowly add 0.5 parts of defoamer, disperse for 13 minutes, the defoamer is poly Ether siloxa...

Abstract

The invention belongs to the field of water-based paint, and particularly relates to water-based finish varnish for a wood holder pencil and a preparation method thereof. The water-based finish varnish comprises the following components in parts by weight: 80 to 100 parts of water-base resin; 3 to 6 parts of a coalescing agent A; 2 to 4 parts of a coalescing agent B; 1 to 2 parts of a wetting agent; 1 to 5 parts of a dispersing agent; 0.2 to 1 part of a defoaming agent; 2 to 5 parts of a thickening agent. The water-based finish varnishis dried quickly, good in adhesive force, high in smoothness and good in hand feeling.

Description

technical field [0001] The invention belongs to the field of water-based paints, and in particular relates to a water-based top coat varnish for wooden pencils and a preparation method thereof. Background technique [0002] Pencil is an important writing tool in the cultural life of modern people. The most traditional wooden pencil is still the main tool in the fields of sketching, painting, examination, and make-up due to its writing characteristics, and has an irreplaceable position. In order to protect and leave the wooden pencil, it must be painted, and to achieve the ideal painting effect, the primer must be applied first, that is, the white primer is applied on the surface of the wooden rod with a paint machine, and then painted Apply a colored topcoat, followed by a top coat of varnish. The purpose of applying the white primer is to cover the texture of the surface of the wooden pole and the original color of the wood, improve the smoothness of the surface, and facil...
