Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a low-temperature-resistant white latex. Background technique [0002] White latex is one of the water-soluble adhesives with the widest application, the largest amount, and the longest history. It is a thermoplastic adhesive prepared by polymerization of vinyl acetate monomer under the action of an initiator. It can be cured at room temperature, cured quickly, and has high bonding strength. The bonding layer has good toughness and durability and is not easy to age. It can be widely used in bonding paper products (wallpaper), and can also be used for bonding waterproof paint and wood, and bonding wood materials. Therefore, it is widely used in printing and binding and furniture manufacturing. It is used as paper, wood, cloth, leather, Adhesives such as ceramics, etc., can also be used as modifiers for adhesives such as phenolic resins, urea-formaldehyde resins, etc.,...

AI Technical Summary

Problems solved by technology

[0003] But this kind of white latex has poor water resistance and moisture resistance, it is easy to absorb moisture in humid air, and it is easy to freeze when stored below -5°C, which will damage the emulsion.
