Problems solved by technology

[0003] At present, water-based coatings are healthier than solvent-based coatings, but the unit price of water-based coatings is much higher than that of solvent-based coatings. Therefore, home improvement manufacturers will face huge cost pressures when improving "oil-to-water" , In this case, home improvement manufacturers generally reduce costs through recycling. This may be easy to achieve for the recycling of panels and cabinet furniture, but for special-shaped furniture, the realization of recycling requires huge investment in equipment

Abstract

The invention provides primer-free waterborne finishing paint for doors and windows. The paint is prepared from, by weight, 60-90 parts of waterborne emulsion, 2-6 parts of film forming auxiliaries, 1-10 parts of other auxiliaries, 5-30 parts of pigment and 1-30 parts of water. The invention further provides a preparation method of the primer-free waterborne finishing paint for doors and windows. The primer-free waterborne finishing paint for doors and windows can be directly coated on formwork drawing putty, and production cost is greatly reduced. Besides, by the adoption of the primer-free waterborne finishing paint for doors and windows, devices in the prior art can still be used, accordingly a complete oil-to-water waterborne coating system is formed, VOC emission is reduced, and safety and environment protection are achieved. The primer-free waterborne finishing paint for doors and windows also has the advantages of being good in adhesion, decorative effect, weather resistance and the like.

Description

technical field [0001] The invention relates to a paint, in particular to a water-based wood paint, in particular to a primer-free water-based finish paint for doors and windows. Background technique [0002] With the development of society and the improvement of people's living standards, consumers have higher and higher requirements for home improvement products, especially for their environmental protection and health and non-polluting requirements. Correspondingly, home improvement manufacturers and raw material manufacturers are also actively involved in the research and development of more environmentally friendly and safer products. Among them, paint is an important raw material for home improvement production, and its quality directly affects the quality of home improvement products. Therefore, a more environmentally friendly, Safer and more convenient coatings are urgently needed by home improvement manufacturers. [0003] At present, water-based coatings are healt...
