Embodiment 1

[0034] A one-component water-based dip-coating and sealing white primer. When painting, the weight ratio of main paint to water is: main paint: water = 1:0.1-0.2;

[0035] The weight percent of the composition of main paint:

[0036]

[0037]

[0038] Evenly dispersed to fineness≤40um, viscosity: 60-70s (coating 4 # coating test).

[0039] The preparation method based on the described one-component water-based dip-coating sealing white primer comprises the steps:

[0040] (1) Add water, defoamer, wetting and dispersing agent into the container, and stir at a low speed;

[0041] (2) Add heavy calcium carbonate, talc powder, titanium dioxide, anti-sedimentation agent, and disperse at high speed until the fineness is ≤40um;

[0042] (3) Then add acrylic emulsion and disperse for 5 minutes;

[0043] (4) Then add the mixture of film-forming aids and water, and disperse for 5 minutes;

[0044] (5) Add substrate wetting agent and leveling agent;

[0045] (6) Add thickener...

Embodiment 2

[0049] A one-component water-based dip-coating and sealing white primer. When painting, the weight ratio of main paint to water is: main paint: water = 1:0.1-0.2;

[0050] The weight percent of the composition of main paint:

[0051]

[0052]

[0053] Disperse evenly to fineness≤40um, viscosity: 60-70s (Tu4#Tu measurement).

Embodiment 3

[0055] A one-component water-based dip-coating and sealing white primer. When painting, the weight ratio of main paint to water is: main paint: water = 1:0.1-0.2;

[0056] The weight percent of the composition of main paint:

[0057]

[0058] Evenly dispersed to fineness≤40um, viscosity: 60-70s (coating 4 # coating test).

[0059] Each performance index and the limited matter of the one-component water-based dipping and sealing white primer of the present invention are as follows:

Abstract

The invention discloses a single-component water-based dip-coating sealing white primer prepared from a polyacrylic emulsion with a self-crosslinking two-phase core-shell structure. Examinations and trails prove that the single-component water-based dip-coating sealing white primer disclosed by the invention is good in sealing effect, the sagging resistance, defoaming speed, dilution and sinking prevention of the primer are superior to those of like products on the market, the substrate adhesive force and bleeding prevention of the primer are very good, the properties and environmental performance of the primer accord with GB / T23999-2009 and GB24410-2009, and the primer is particularly suitable for first dip-coating of wood wares.

Description

technical field [0001] The invention is a one-component water-based dipping and sealing white primer, which is a one-component water-based wood paint made from acrylic emulsion as the main raw material. Background technique [0002] In the current prior art, the one-component water-based dip-coating and sealing white primer is a white paint with excellent comprehensive performance and environmental protection. However, some one-component water-based dip-coating white primers sold on the market have unsatisfactory defoaming properties after construction, poor anti-sagging properties, poor thinning and anti-settling properties, and unsatisfactory comprehensive performance, which greatly affects the coating of furniture. Effect. Contents of the invention [0003] The purpose of the present invention is to solve some problems in the middle of above-mentioned dip-coating and prepare the water-based dip-coating white primer with excellent comprehensive properties of sealing, de...
