Generally speaking, any non-metallic substance that can adhere a material to the surface of another material to meet certain physical and chemical properties can be called a binder. The adhesives used in the decoration can be divided into the following categories according to their performance, characteristics and specificity:
1. White Latex: It is mainly suitable for the bonding of wooden keel base, wooden base layer and finished wooden surface board. It is also suitable for wall wallpaper, wall surface greasy paste and increased glue strength. The main component of white latex is vinyl acetate monomer polymer, which can be emulsified in water. The white latex is glued by evaporation of water, and the operation is relatively simple and safe. The curing speed is faster at normal temperature, the bonding strength is better, the expansion and contraction are not basically performed, the bonding life is long, and the bonding is elastic.
2, 108 glue: 108 glue is the upgraded product of 107 glue. It is a water-soluble colloid synthesized by polyvinyl alcohol reaction. This colorless and transparent new building material has very low formaldehyde content, good bonding performance and strong cementation ability. , anti-bacterial and anti-aging. 108 glue is suitable for sticking wall and floor tiles in indoor room temperature environment, and can also be used for wallpaper paste. However, the base layer should be dense and free of floating ash. If the wall surface is loose or smooth, an interface agent is required for interface treatment.
3. Interfacial agent: The interface agent is generally milky white glue, which has good permeability. It can fully wet the base layer of the wall, make the base layer dense, improve the adhesion of the smooth base layer, ensure the cement is firm and reliable, and can improve the putty, mortar and wall. The bond strength of the body surface prevents empty drums. The interface agent is suitable for the interface treatment of the wall surface putty or the base layer before plastering, and also applies to the cement lapping treatment of the base wall before the tile is applied, and can also be applied to the wall cloth.
4, floor, stone adhesive: this kind of adhesive can be used for the bonding of the floor and stone, the regular floor glue has a shorter solidification time, high bonding strength and long service life; common stone adhesive There is marble glue, which is mainly suitable for the docking, repairing and finishing of various marbles. The marble glue solidifies quickly, without expansion and contraction, but is easily broken by impact.
In addition to the above commonly used adhesives, there are also adhesives such as wallpaper glue, glass glue, waterproof sealant, etc. During the decoration, the adhesive used by the construction team should have a detailed understanding of its performance, especially whether the environmental indicators can meet the standard. Avoid decoration pollution.
After knowing the above things, home improvement environmental protection has become the consensus of people's decoration. Many consumers pay great attention to environmental protection indicators when choosing wall paint, flooring, wallpaper, ceramic tile and other decoration materials. However, the ubiquitous adhesive in the decoration is easy to be neglected, and the unqualified adhesive often becomes the "invisible killer" of the pollution of the living room decoration.
