Problems solved by technology

[0002] In order to protect the wooden interior parts of automobiles, some sealing coatings can be coated on the surface. However, most sealing coatings in China are solvent-based products with high VOC content and strong pungent odor. The environment is potentially harmful, and solvent-based products are flammable and explosive, and have high fire protection requirements
In addition, the sealing effect of the existing sealing paint still needs to be strengthened, and the painted car wood interior is still prone to problems such as bleeding, discoloration, and cracking

Embodiment 1

[0024] A water-based nano-sealing coating for car wood interiors, comprising the following raw materials by mass percentage: 70% of water-based nano-resin; 28.3% of deionized water; 0.1% of water-based acid-base balance agent; 0.1% of water-based surfactant; Water-based dispersant 1%; water-based thickener 0.5%.

[0025] The preparation method of this water-based nano sealing coating comprises the steps of: putting water-based nano-resin and deionized water into a mixing bucket, stirring for 5 minutes with an electric mixer at 500 rpm at normal temperature, and then balancing the water-based acid-base in the stirring process Put the agent, water-based surfactant, water-based dispersant, and water-based thickener into the mixing tank in sequence, and stir with an electric mixer at 1000 rpm for 20 minutes.

Embodiment 2

[0027] A water-based nano-sealing paint for automotive wooden interiors, comprising the following raw materials by mass percentage: 72% of water-based nano-resin; 25.4% of deionized water; 0.3% of water-based acid-base balance agent; 0.2% of water-based surfactant; Water-based dispersant 1.5%; water-based thickener 0.6%.

[0028] The preparation method of this water-based nano sealing coating comprises the following steps: put water-based nano-resin and deionized water into a mixing tank, stir with an electric mixer at 400 rpm for 10 minutes at normal temperature, then balance the water-based acid-base in the stirring process Put the agent, water-based surfactant, water-based dispersant, and water-based thickener into the mixing tank in turn, and stir with an electric mixer at 800 rpm for 25 minutes.

Embodiment 3

[0030] A water-based nano-sealing paint for automotive wood interiors, comprising the following raw materials by mass percentage: 75% of water-based nano-resin; 22.1% of deionized water; 0.4% of water-based acid-base balance agent; 0.1% of water-based surfactant; Water-based dispersant 1.6%; water-based thickener 0.8%.

[0031] The preparation method of this water-based nano sealing coating comprises the steps of: putting water-based nano-resin and deionized water into a mixing tank, stirring for 4 minutes with an electric mixer at 600 rpm at normal temperature, and then balancing the water-based acid-base in the stirring process Put the agent, water-based surfactant, water-based dispersant, and water-based thickener into the mixing tank in turn, and stir with an electric mixer at 1200 rpm for 18 minutes.

Abstract

The invention discloses a water-based nano sealing coating for an automobile wood interior and a preparation method of the water-based nano sealing coating. The water-based nano sealing coating comprises the following raw materials in percentage by mass: 66-80% of water-based nano resin; 16%-30% of deionized water; 0.1%-0.5% of a water-based acid-base balancing agent; 0.1%-0.5% of a water-based surfactant; 1%-2% of a water-based dispersant; and 0.5%-1% of a water-based thickening agent. The water-based nano sealing coating disclosed by the invention can be used for well sealing the automobile wood interior trim, isolating internal pigment permeation of the automobile wood interior trim and permeation of water vapor in air, solving the sealing problem of the automobile wood interior trim, enabling the automobile wood interior trim not to be easy to bleed, discolor and crack, greatly reducing the VOC content, and being non-toxic and odorless; the paint can well protect the safety of coating workers and environment in a vehicle factory, and is a non-dangerous chemical. In addition, the water-based nano sealing coating is convenient to prepare, reasonable in proportion and low in production cost.

Description

technical field [0001] The invention relates to the technical field of automotive interior coatings, and more specifically relates to a water-based nano-sealing coating for automotive wood interiors and a preparation method thereof. Background technique [0002] In order to protect the wooden interior parts of automobiles, some sealing coatings can be coated on the surface. However, most sealing coatings in China are solvent-based products with high VOC content and strong pungent odor. The environment is potentially harmful, and solvent-based products are flammable and explosive, and have high fire protection requirements. In addition, the sealing effect of the existing sealing coatings still needs to be strengthened, and the painted car wood interior is still prone to problems such as bleeding, discoloration, and cracking. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defect in the prior art, provide a kind of w...
