Problems solved by technology

[0004] (1) During construction in areas with high humidity and high underground water vapor, it is easy to produce blisters, water vapor, etc., resulting in the phenomenon of "drumming" of the epoxy floor, which affects the appearance and service life of the epoxy floor;
[0005] (2) The organic solvents added during construction will cause great harm to the construction personnel on site; after the floor paint is cured, the volatile solvents will slowly release harmful substances, causing secondary environmental pollution;
[0006] (3) Flammable and explosive volatile solvents pose a threat to fire safety during use;
[0007] (4) Under extreme temperature and humidity conditions, the paint film is easy to burst, fall off, and peel, which affects the normal production and causes environmental pollution

Embodiment 1

[0034] The preparation method of the waterborne polyurethane floor coating of embodiment 1 is as follows:

[0035] The preparation method of component A is: add the polyol into the emulsification kettle and heat it to 60°C, add the emulsifier into the emulsifier under stirring, keep warm until it dissolves, then add the emulsifier and defoamer, stop heating, and increase the stirring speed to 5000rpm, and add water while stirring, after the water is added, it can be ground by a colloid mill to obtain component A.

[0036] The preparation method of component B is: keep the indoor humidity less than 50%, pour polyisocyanate into the product packaging;

[0037] The preparation method of component C is as follows: put white cement, toner, sodium metasilicate, water reducing agent and quartz sand specified in the formula into a dry powder mixer, mix them evenly, sieve and pack to obtain component C. When in use, weigh and mix components A, B, and C according to the mass ratio, and...

Embodiment 2

[0038] The preparation method of the waterborne polyurethane floor paint of embodiment 2 is as follows:

[0039] The preparation method of component A is: add the polyol into the emulsification kettle and heat it to 80°C, add the emulsifier into the emulsifier under stirring, keep warm until it dissolves, then add the emulsifier and defoamer, stop heating, and increase the stirring speed to 10000rpm, and add water while stirring, after the water is added, it can be ground by a colloid mill to obtain component A.

[0040] The preparation method of component B is: keep the indoor humidity less than 50%, pour polyisocyanate into the product packaging;

[0041] The preparation method of component C is as follows: put white cement, toner, sodium metasilicate, water reducing agent and quartz sand specified in the formula into a dry powder mixer, mix them evenly, sieve and pack to obtain component C. When in use, weigh and mix components A, B, and C according to the mass ratio, and ...

Embodiment 3

[0042] The preparation method of the waterborne polyurethane floor paint of embodiment 3 is as follows:

[0043] The preparation method of component A is: add the polyol into the emulsification kettle and heat it to 90°C, add the emulsifier into the emulsifier under stirring, keep warm until it dissolves, then add the emulsifier and defoamer, stop heating, and increase the stirring speed to 1000rpm, and add water while stirring, after the water is added, it can be ground by a colloid mill to obtain component A.

[0044] The preparation method of component B is: keep the indoor humidity less than 50%, pour polyisocyanate into the product packaging;

[0045] The preparation method of component C is as follows: put white cement, toner, sodium metasilicate, water reducing agent and quartz sand specified in the formula into a dry powder mixer, mix them evenly, sieve and pack to obtain component C. When in use, weigh and mix components A, B, and C according to the mass ratio, and t...

Abstract

The invention discloses a heavy-load resistance and corrosion-resistance waterborne polyurethane floor coating and a preparation method thereof. The waterborne polyurethane floor coating comprises acomponent A, a component B and a component C, wherein the component A comprises polyol, an emulsifier, a defoaming agent, a flatting agent and water; the component B comprises polyisocyanate; and thecomponent C comprises white cement, toner, sodium metasilicate, a water reducing agent and quartz sand. The preparation method comprises the following steps that firstly, the component A and the component C are separately prepared, and then the three components A, B and C are mixed during use. The coating has low viscosity, high solid content, no solvent volatilization, rapid drying and long recoating time, can realize thick-film formation, and has high adaptability to coating environment, so that the requirements of various factories on rapid and environment-friendly coating are met.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a heavy-duty and corrosion-resistant water-based polyurethane floor coating and a preparation method thereof. Background technique [0002] Modern industry has put forward more and more stringent requirements on the floor. For example, food, medicine and other industries require the floor to be free from ash, no harmful volatiles, and clean and dust-free; the machinery industry requires strong mechanical shock resistance, wear resistance, and energy It has been rolled and rolled by vehicles such as forklifts for a long time, and it is easy to repair even if it is partially damaged; the floors of industrial workshops such as machine tools and instruments are often corroded and leaked by various oils, which are difficult to completely remove. The floor requires good oil resistance, and the chemical industry requires floor The ping can resist the corrosion of various ch...
