Classification of Construction Adhesives

Building adhesives are essential materials in construction projects and are widely used. In the process of building decoration and renovation, they are mainly used for board bonding, wall pretreatment, wallpaper pasting, ceramic wall and floor tiles, various floors, carpet laying and bonding, etc., adding a series of properties such as waterproofness, sealing, elasticity, and impact resistance, which can not only improve the quality of building decoration, increase beauty and comfort, but also improve construction technology, improve construction efficiency and quality, etc.

1. Classification by form:

 Aqueous solution: polyvinyl alcohol, cellulose, phenolic resin, urea-formaldehyde resin, sodium silicate, etc.; Solution: nitrocellulose, cellulose acetate, polyvinyl cellulose, chloroprene rubber, nitrile rubber, etc.; Emulsion (latex): polyvinyl acetate, polyacrylic acid ester, natural latex, chloroprene latex, nitrile latex, etc.; Solvent-free type: epoxy resin, acrylate, cyanoacrylate, etc.; Solid type: Powder: starch, casein, polyvinyl alcohol, copper oxide, etc.; Sheet, block: fish glue, rosin, hot melt glue, shellac, etc.; Rope: epoxy glue stick, hot melt glue, shellac, etc.; Film: phenolic-polyvinyl alcohol acetal, phenolic-nitrile, epoxy-nitrile, epoxy-polyamide, etc.; Strip: adhesive type, heat seal type; Paste and putty

2. Classification by curing type:

Physical curing: solvent-based, emulsion-based, hot melt-based, etc. Chemical curing: moisture curing, water hardening, anaerobic curing, reaction curing, etc.;

3. Classification by bonding strength and hardness:

Structural type: Building structural adhesive: steel adhesive, anchoring adhesive (anchoring adhesive), injection adhesive, carbon fiber reinforcement adhesive, etc.; Curtain wall structural adhesive: dry hanging adhesive, silicone structural adhesive; Non-structural type: Adhesive adhesive: floor adhesive, floor tile adhesive, wallpaper adhesive, plastic pipe adhesive, stone adhesive, bamboo and wood adhesive, etc.; Sealant: polysulfide sealant, butyl sealant, silicone sealant, etc.

4. Classification by use part:

Tile adhesive: mainly used for indoor and outdoor pasting of various wall and floor tiles. Stone adhesive: mainly used for bonding of various stones such as marble and granite. Interface treatment agent: mainly used for interface treatment and bottom sealing adhesive. Board seam and block adhesive: mainly used for bonding and board seam treatment of various partition boards and gypsum boards. Putty glue: mainly used for leveling cement putty.

5. Classification by chemical composition:

Polysulfide rubber, chloroprene rubber, acrylic, polyurethane, butyl rubber, silicone rubber, rubber-plastic composite, thermoplastic elastomer, etc.
