Anti-freezing white latex

Abstract

The invention relates to the technical field of chemical industry production, particularly to an anti-freezing white latex capable of resisting low temperature, wherein the anti-freezing white latex comprises, by weight, 90-110 parts of polyvinyl acetate, 60-80 parts of vinyl acetate, 30-40 parts of polyvinyl alcohol, 10-15 parts of acrylic acid, 6-13 parts of butyl acrylate, 10-15 parts of ammonium persulfate, 30-40 parts of diethylene glycol dibenzoate, 15-25 parts of sodium bicarbonate, 10-15 parts of dibutyl phthalate, 0.5-3 parts of an emulsifier, and 60-80 parts of water, wherein the acrylic acid is sulfuric acid acrylic acid, and the polyvinyl alcohol is polyvinyl butanol.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to an antifreeze 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. [0003] 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. [0004] 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, e...

Problems solved by technology

[0005] 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.
