Embodiment 1

[0056] This embodiment provides a water-based fast-drying wear-resistant wooden floor coating for containers, which is prepared by the following method.

[0057] 1) The following mass fraction (in terms of mass fraction in wear-resistant slurry) raw materials: titanium aluminum nitride 20%, nylon substrate TPSiV 30% and solvent ethylene glycol butyl ether 50% are added in the container, and in While adding raw materials, carry out mechanical stirring (800r / min speed); after adding raw materials, select high-speed dispersion (2300r / min speed) for 10 minutes, and then ultrasonically disperse (25KHz frequency) for 10 minutes to obtain a wear-resistant slurry. .

[0058] 2) Add 20% deionized water (based on the mass fraction in the coating), and add a composite film-forming aid (PnP, Dow Chemical 3%, Texanol, American Eastman 2.0%) under the condition of stirring at a speed of 600r / min Stir for 8 minutes; when the solution is lowered to room temperature, the composite environment...

Embodiment 2

[0062] This embodiment provides a water-based fast-drying wear-resistant wooden floor coating for containers, which is prepared by the following method.

[0063] 1) Add the following raw materials in the mass fraction: titanium aluminum nitride 30%, nylon substrate TPSiV 20% and solvent 50% into the container, and mechanically stir (900r / min speed) while adding the raw materials; after the raw materials are added , choose high-speed dispersion (2450r / min speed) for 12 minutes, and then ultrasonic dispersion (23KHz frequency) for 12 hours, that is, the wear-resistant slurry is prepared for use.

[0064] 2) Add 15% of deionized water, under the stirring condition of 800r / min rotating speed, add the composite film-forming aid (PPh, Dow Chemical 3%, PnP, Dow Chemical 1%) in the formula and stir for 12min; to room temperature, that is, the composite environment-friendly film-forming aid mixed solution is prepared for subsequent use;

[0065] 3) Add 76% of water-based self-crosslin...

Embodiment 3

[0067] This embodiment provides a water-based fast-drying wear-resistant wooden floor coating for containers, which is prepared by the following method.

[0068] 1) Add the following raw materials in mass fractions: 40% of titanium aluminum nitride, 10% of nylon substrate TPSiV and 50% of solvent into the container, and mechanically stir (900r / min speed) while adding the raw materials; after the raw materials are added , choose high-speed dispersion (2200r / min speed) for 10 minutes, and then ultrasonic dispersion (50KHz frequency) for 12 minutes, that is, the wear-resistant slurry is prepared for use.

[0069] 2) Add 5.1% deionized water, and under the stirring condition of 700r / min, add the composite film-forming aid in the formula (propylene glycol methyl ether PM, Dow Chemical 1.5%, propylene glycol butyl ether PnB, Dow Chemical 1.5%) Stir for 10 minutes; when the solution drops to room temperature, the composite environment-friendly film-forming aid mixed solution is prepa...

Abstract

The invention relates to a water-based quick-drying wear-resistant wooden floor coating for containers and a preparation method thereof. The container water-based fast-drying wear-resistant wooden floor coating is composed of the following components in mass fractions: water 10-25.1%, water-based self-crosslinking core-shell polyurethane dispersion 70-85%, wear-resistant slurry 2-5%, Water-based wetting agent 0.1-0.4%, water-based stabilizer 0.2-0.8%, pH regulator 0.1-0.3%, film-forming aid 3-5%, water-based defoamer 0.1-0.3%, water-based anti-mold fungicide 0.2- 0.5%, water-based thickener 0.2-0.5%. The water-based quick-drying and wear-resistant wooden floor coating for containers provided by the invention is a single-component coating, which is convenient for construction, safe and environmentally friendly, and low in cost.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically relates to a water-based quick-drying wear-resistant wooden floor coating for containers and a preparation method thereof. Background technique [0002] Water-based coatings are non-flammable, non-explosive, safe and environmentally friendly, making water-based coatings for containers an inevitable trend of development. In recent years, major domestic container factories have actively cooperated with the development, and have carried out technical transformation on the coating equipment and processes of the container production line, and have made every effort to promote water-based coatings for containers. At present, the domestic container industry and Guangdong Province have respectively formulated and implemented the container industry regulation JH / T E06-2015 "Water-based Coatings for Containers" and the local standard DB44 / T 1599-2015 "Water-based Container Coatings" ...
