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.,...
