As an adhesive or coating, acrylic emulsion can be used as a binder for fiber bonding in the production process of ceramic fiber paper. In the production process of ceramic fiber paper, acrylic emulsion is used as a binder for fiber bonding, mainly for the following reasons: Good bonding performance Acrylic emulsion has excellent bonding strength and can effectively bond ceramic fibers together to form a stable structure. The polar groups in its molecular structure can interact with the surface of ceramic fibers, enhancing the bonding effect. High temperature resistance Ceramic fiber paper is usually used in high-temperature environments. After appropriate modification, acrylic emulsion can have good high-temperature resistance, maintaining its bonding performance under high-temperature conditions and ensuring the structural stability of the ceramic fiber paper. Chemical corrosion resistance Acrylic emulsion has good chemical corrosion resistance and can resist the erosion of chemical substances that the ceramic fiber paper may come into contact with during use, extending the service life of the paper. Environmental friendliness Acrylic emulsion is a water-based emulsion with water as the dispersion medium, making it environmentally friendly and meeting the environmental requirements of modern industry. It reduces the use of organic solvents and lowers environmental pollution. Film-forming performance Acrylic emulsion has good film-forming properties and can form a uniform thin film on the surface of ceramic fibers, wrapping the fibers and improving the strength and water resistance of the paper. In summary, acrylic emulsion has become a commonly used adhesive in the production of ceramic fiber paper due to its advantages in bonding performance, high-temperature resistance, chemical corrosion resistance, environmental friendliness, and film-forming performance.

Water-based polyurethane textile coating technology is widely used in the textile industry, with different coating methods suitable for different production needs and product functions. The following details five main water-based polyurethane coating methods, including their principles, advantages, and typical application areas. Dip Coating Dip coating is a basic and effective water-based polyurethane coating process. The principle involves directly immersing the fabric in a water-based polyurethane emulsion. Uniform coating is achieved by controlling the immersion time, temperature, and emulsion concentration. This method is simple, easy to operate, and particularly suitable for small-batch production or experimental research. Dip coating is often used for preliminary experiments on functional textiles, such as the development and testing of waterproof and stain-resistant coatings. Pad-Batch Process The pad-batch process is a continuous coating process, mainly including three steps: padding, drying, and heat curing. First, the fabric is immersed in a bath containing water-based polyurethane using rollers to control the liquid content; then it enters the drying stage to remove water and form a preliminary coating; finally, heat curing promotes the cross-linking of polyurethane molecules, enhancing the strength and durability of the coating. This process is highly controllable and suitable for large-scale continuous production, widely used in clothing fabrics, tents, outdoor products, and other fields. Spray Coating Spray coating utilizes atomization technology to evenly spray the water-based polyurethane emulsion onto the fabric surface, and the coating thickness is controlled by airflow. This method is suitable for fabrics with complex shapes or three-dimensional structures, providing uniform coating distribution and good coverage. Spray coating is often used in products requiring high coating uniformity, such as automotive interiors, protective clothing, and home textiles. Knife Over Roll Coating Knife over roll coating uses a doctor blade to evenly remove excess water-based polyurethane emulsion, thereby forming a coating of precise thickness on the fabric surface. This method offers extremely precise control over coating thickness and is suitable for applications requiring high precision, such as medical protective clothing and precision filtration materials in industrial textiles. Composite Modification Method To improve the performance of water-based polyurethane coatings, composite modification techniques are often employed. Blend modification enhances the weather resistance and abrasion resistance of coatings by blending water-based polyurethane with materials such as acrylates and silanes; nanocomposite technology imparts special properties to coatings by adding functional nanomaterials such as nano-titanium dioxide (for UV resistance) or nano-silver (for antibacterial properties); and crosslinking technology further improves the durabil...
