What glue is used to bond pearl cotton
Pearl cotton is a new type of environmentally friendly packaging material, and it is often seen in car seat cushions, pillows, instruments and other items. So what glue is used to bond the pearl cotton?
EPE is mainly used for bonding with hot melt glue. Because hot melt adhesive is a plastic adhesive, it is in a solid state at room temperature, and can be quickly bonded after heating and melting. In addition, the cost is low, green and environmental protection, and there is no need to add solvents during use, and there is no need to worry about the defects such as deformation, dislocation and shrinkage of the pearl cotton, which helps to reduce costs. However, hot melt adhesives are not suitable for use as structural adhesives.
Two. What are the commonly used pearl cotton adhesives?
In addition to hot melt adhesives, there are various new types of adhesives on the market. The common one is single-sided gluing, which is suitable for large bonding area, the other is double-sided gluing, which is suitable for small bonding area, and the third is using machine gluing.
1. One-sided gluing
First pour the glue on the pearl cotton to be bonded, then apply the glue evenly on the surface of the pearl cotton with a scraper or a brush, and then stick the two pieces of pearl cotton together. This kind of glue is slow-drying Type, the normal glue layer is dried in 15 to 30 minutes, and it will be completely cured in 24 hours. After the glue is completely cured, the effect of pearl cotton can be achieved without degumming.
2. Double-sided glue
Apply the glue evenly on the two surfaces that need to be bonded to the pearl cotton material, let it dry for 3 to 5 minutes, it is advisable to touch the glue layer with your hand without drawing, and then stick the two pearl cotton materials firmly (double-sided glue). Compared with single-sided gluing, the advantages are fast positioning speed and high bonding strength).
2. Machine gluing
This kind of glue has a high solid content, and the glue is relatively more viscous, so a certain proportion of thinner can be added to dilute the glue. According to the normal proportion, it does not affect the bonding performance of the glue, which can save a certain cost.
