Panoramic analysis of the whole scene application of water-based acrylic lotion(1)

With the continuous tightening of domestic environmental regulations, low-VOC and environmentally friendly polymer materials are rapidly replacing traditional solvent-based products, with water-based acrylic emulsions serving as the core representative material in this trend. As a water-dispersed, eco-friendly polymer resin dispersion, it has penetrated dozens of industries, including architectural coatings, industrial corrosion prevention, adhesives, textiles and leather, printing and packaging, and even new energy sectors, becoming a key foundational material supporting the green transformation of multiple industries.

In the field of interior wall and exterior wall latex paint, pure acrylic and styrene acrylic lotion, with outstanding weather resistance and UV aging resistance, ensure that the coating will not be powdery for a long time and the color will last for a long time, and at the same time meet the requirements of tens of thousands of times of scrub resistance. They are widely used in the interior and exterior wall coating of various buildings such as residential buildings, schools, hospitals, etc. In the real stone paint and texture coating system, it provides strong adhesion as a continuous phase, allowing the sand material and colored sand to firmly adhere to the wall, avoiding peeling and whitening problems after long-term outdoor use. In addition, waterproof coatings and floor coatings are also important application directions. The two-component JS waterproof coating made with cement powder has both flexibility and adhesive strength after film formation, and can be used for waterproof protection in damp areas such as roofs, basements, and bathrooms; The water-based floor coating used in garage and factory workshop greatly improves the service life of the floor by relying on the wear-resistant and anti-skid properties brought by lotion. For the strong penetration sealing primer for loose base course, the special acrylic lotion, with small particle size and high permeability, can go deep into the wall to strengthen the floating ash and provide stronger adhesion for the subsequent putty layer. This kind of product has been supported by a number of invention patents, and its technical maturity is at the leading level in the industry.

In the field of industrial coating and anti-corrosion, water-based acrylic lotion is gradually replacing traditional solvent based coatings, promoting the low-carbon transformation of industrial production. In light anti-corrosion scenarios, it is widely used as a primer and topcoat system for steel structures, mechanical equipment, and pipelines. The modified product can achieve salt spray resistance for more than 500 hours, meeting the metal protection requirements in conventional industrial environments. For plastic paint and metal baking paint of auto parts, home appliance shells and 3C electronic products, the special lotion suitable for metal and plastic substrates can provide a high gloss and high hardness coating, while taking into account the characteristics of quick drying, alcohol resistance and abrasion resistance, and adapting to the efficient production of industrial production lines. In the wood coatings track, water-based acrylic lotion has become the mainstream choice for furniture, wood floors and children's toys coating. The characteristics of low odor and low VOC fully meet the requirements of home environmental protection. Some yellowing resistant models can keep the coating transparent for a long time to avoid yellowing and aging problems in the use of light colored furniture.

Adhesive and packaging industry is the second largest application track of water-based acrylic lotion, and pressure sensitive adhesive is its most representative application direction. From daily use of sticky notes, express sealing tape, product labels, to protective films used on electronic products and building materials, water-based acrylic pressure-sensitive adhesives rely on their stable adhesion and tear off residue free properties, occupying the majority of the market share of adhesive products. In the field of packaging composites, it can be used for paper plastic and plastic plastic composite bonding in food and drug packaging. Its safe and non-toxic characteristics meet the requirements for food contact level use. At the same time, it exhibits excellent heat and moisture resistance in vacuum suction plastic scenes for automotive interiors and wooden door production, ensuring that the bonding area does not crack for a long time. Compared to traditional formaldehyde based urea formaldehyde adhesives, water-based acrylic wood adhesives without formaldehyde additives have been widely used in the production of plywood and density boards, reducing the release of harmful substances from the source of artificial boards.

Light industry fields such as textile, leather, printing and papermaking are also important application fields of water-based acrylic lotion. In the textile industry, as a fabric coating agent, it can endow fabrics with different functions such as waterproofing, flame retardancy, and anti-static by adjusting the formula, adapting to the production needs of special fabrics such as tent fabrics and protective clothing; As a coating printing adhesive, it can firmly fix the pigment on the surface of the fiber, ensuring that the printed pattern is washable and the color fastness meets the standard. In the leather processing stage, it is used as a film-forming agent for the coating treatment of shoe uppers and bags. The gloss and feel of the coating can be adjusted according to the needs, improving the surface resistance and wear resistance of the leather. In the field of printing and papermaking, water-based acrylic lotion is the core binder of water-based flexographic and gravure inks. Its low odor characteristics meet the environmental requirements of food packaging printing; Simultaneously used for surface coating of copperplate paper and white cardboard, enhancing the glossiness and printability of the paper, making the printed patterns clearer and fuller.

In recent years, the application boundary of waterborne acrylic lotion is continuously expanding to emerging fields. In the new energy industry, it is used as a coating for lithium battery separators to enhance their high-temperature resistance and ensure the safety of battery use; In the field of electronic materials, it can be used as a component of temporary protective coatings for circuit boards and packaging adhesives for electronic components. In addition, waterborne acrylic lotion can also be seen in 3D printing scenes such as light curing resin, concrete curing agent and seam beauty agent. With the continuous iteration of technologies such as organic silicon modification and nanocomposites, it will also extend to high-end functional scenarios such as self-cleaning and self-healing in the future, providing material support for the green upgrading of more industries.
