Abstract
The invention discloses a carbon-fixed odor-removing water-based resin, and a preparation method and application thereof. The preparation raw materials of the carbon-fixed odor-free water-based resin comprise: a first precursor polymer and a second precursor polymer; the preparation raw materials of the first precursor polymer comprise poly (carbonate-ether) polyol and diisocyanate; the second precursor is prepared from castor oil, diisocyanate and polyethylene glycol. The carbon-fixed odor-free water-based resin has good hand feeling and lower odor, can form a film, and has excellent wrapping property on pigment and filler, so that the interior wall coating has the characteristics of low odor, excellent water resistance, excellent washing resistance and smooth hand feeling.
Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to a carbon-fixed odor-free water-based resin, and a preparation method and application thereof.
Background
The paint is coated on the surface of the protected or decorated object and can form a continuous film firmly attached to the coated object, and the paint is usually based on at least one of resin, oil and emulsion, and pigment, filler and corresponding auxiliary agents can be added.
In current interior wall application systems, acrylic emulsions dominate. However, the acrylic emulsion has the common performance defects of hot adhesion, cold brittleness, poor hand feeling, scratch resistance and the like, so that the overall quality of a paint film is affected, and the increasingly improved consumer demands are difficult to meet. The water-based polyurethane resin is synthesized by taking carbon dioxide as an initial stage reaction monomer, and then the water-based paint (namely the carbon fixing paint) is prepared, so that a new technical route is provided for carbon emission reduction in the paint field. However, existing carbon fixing coatings often require additional film forming aids to aid in film formation, and thus the coatings are higher in VOC and odor; in addition, the conventional carbon-fixing paint is limited to a transparent paint system, and has the defects of poor pigment and filler coating property, poor film forming property and the like in application, and particularly has poor washing resistance, so that the carbon-fixing paint is difficult to apply to odorless powder paint.
In conclusion, the carbon-fixed odor-free water-based resin based on the greenhouse gas carbon dioxide is developed, and the environment-friendly formula is combined to prepare the water-based odor-free coating with excellent performance, so that the use experience of consumers is improved, and the requirements of environmental protection and sustainable development can be met.
