Abstract

The invention belongs to the technical field of water-based wood coatings. The invention relates to a wood coating, in particular to an environment-friendly antibacterial waterborne wood coating and apreparation method thereof. The composition comprises the following materials in parts by weight: 60 to 80 parts of a waterborne polyurethane dispersion emulsion, 2 to 10 parts of a surface additive,and 1 to 15 parts of a film forming aid, 2 to 5 parts of a biquaternary ammonium salt bactericide, 0.1 to 1 part of a nano-silver bactericide, 0.1 to 1 part of a nano-zinc antibacterial agent, 1 to5 parts of a biguanide antibacterial agent, 1 to 5 parts of a chitosan antibacterial agent, 3 to 5 parts of an organosilicon waterproofing agent, 10 to 40 parts of distilled water, 0.1 to 2 parts of an anti-settling agent and 0.1 to 1 part of a thickener. The antibacterial waterborne polyurethane coating has remarkable antibacterial and bactericidal effects, and is enhanced in the aspects of bactericides and waterborne polyurethane dispersoid emulsion, so that the antibacterial function of the coating is increased on the basis of the original waterborne coating performance, and the multifunctional balance of antibacterial, environment-friendly, stable, long-acting and coating performance can be achieved.

Description

technical field [0001] The invention belongs to the technical field of water-based woodware coatings, in particular to an environment-friendly and antibacterial water-based woodware coating and a preparation method thereof. Background technique [0002] The mechanism of action of quaternary ammonium salt fungicides is mainly that cations adsorb negatively charged bacteria through electrostatic force, hydrogen bond force, and hydrophobic binding between surfactant molecules and protein molecules, and gather on the cell wall, resulting in room resistance effect, resulting in The growth of bacteria is inhibited and they die. At the same time, its hydrophobic alkyl group can also interact with the hydrophilic group of bacteria to change the permeability of the membrane, and then lyse, destroy the cell structure, and cause cell dissolution and death. This type of bactericidal The agent has the characteristics of high efficiency, low toxicity, not easily affected by pH changes, ea...
