Water-based coating composition

Abstract

The embodiment of the invention discloses a water-based coating composition. The water-based coating composition is prepared from, by weight, 60-90 parts of acrylic emulsion, 3-12 parts of a film-forming auxiliary, 0.2-0.5 part of defoamer, 0.3-0.6 part of a base material wetting agent, 4-25 parts of a scratch-resistant agent, 0.4-0.8 part of accelerant, 0.4-1 part of a flatting agent, 0.1-0.5 part of a pH conditioning agent and 0.2-0.5 part of an antiseptic antimildew agent. According to the water-based coating composition, scratch resistance, alcohol resistance, water resistance and stain resistance of a paint film are excellent, adhesive force on a commonly used substrate is good, the water-based coating composition is rapid to dry, resistant to a high temperature, not prone to after-tack and environmentally friendly, coating of the composition on a product can be realized through various operation modes without a curing agent, the paint film formed after coating is conducted is high in density and hardness and resistant to impact of heavy objects, an aqueous solution or other commonly used liquid does not permeate into the paint film easily, and the water-based coating composition is suitable for surface coating of various types of bamboo and wood furniture and artware.

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to a water-based coating composition. Background technique [0002] With the development of industrial production, there is an increasing demand for various coatings, especially functional coatings that can meet the needs of specific industries. [0003] Paint is a chemical product made of resin and oil, with or without pigment. After the paint is applied on the surface of the object, it can dry and form a film, so that the surface of the object to be coated is isolated from the environmental medium, thereby playing a corresponding protective and decorative role on the object to be coated. Among them, according to different functions, coatings can include: decorative coatings, anti-corrosion coatings, heat-insulating coatings, and fire-resistant coatings. In recent years, with the improvement of people's quality of life, the pursuit of culture and art, and the enhancement of envir...

Problems solved by technology

[0004] However, most of the current bamboo and wood furniture are mainly oil-based paints, which are not conducive to environmental protection and cause great harm to the human body. However, the water-based paints commonly used in the market have mediocre performance, poor chemical resistance, and the paint film is easy to be scratched. Residual traces are difficult to remove. Secondly, some water-based paints cannot withstand the temperature difference between day and night. The paint film formed after hard drying is easy to crack, has poor flexibility, poor chemical resistance, heavy odor, is unfriendly to the environment, and the drying speed is slow. , the paint film after the product is stored at high temperature is easy to be sticky and other shortcomings, which seriously restricts the production of high-end furniture and is not conducive to the development of water-based paint
