Problems solved by technology

[0003] However, there are certain problems in the water-based film adhesives currently on the market, which are mainly manifested in the poor adaptability of inks and post-processing (such as embossing, embossing, etc.), which cannot replace solvent-based adhesives; and their prices are relatively low. High, the printing industry has limited capacity, so it cannot be used on a large scale

Embodiment Construction

[0020] Below in conjunction with specific embodiment the present invention is described in further detail:

[0021] A water-based dry-type film-covering adhesive is characterized in that the synthetic raw material of soap-free self-crosslinking copolymer emulsion comprises the following components in parts by mass:

[0022] Styrene (ST): 44~48 Butyl acrylate (BA): 45~52

[0023] Methacrylic acid (MA): 3~4 Vinyl tertiary carbonate (VV-10): 3~5

[0024] Ammonium persulfate (APS): 0.4~0.7 Cross-linking monomer: 4~5

[0025] Reactive emulsifier: 3~5 tert-butyl hydroperoxide: 0.1~0.2

[0026] Carved white block: 0.1~0.2 Saturated ammonia water: 2~3.

[0027] The polymerization method of water-based dry-type laminating adhesive comprises the steps:

[0028] (1) Pre-emulsified monomer:

[0029] First, add 30% deionized water into the pre-emulsification tank, then add 50% reactive emulsifier, start stirring, and then add styrene (ST), butyl acrylate (BA), The mixture of methacry...

Abstract

The invention relates to a water dry-type laminated adhesive and a method for polymerizing the same, and provides an adhesive which uses a water adhesive to replace solvent, so as to save resources to the utmost extent, improve the environment and bring better environmental protection performance to the printing-packaging industry at the same time. The polymerization method based on the water dry-type laminated adhesive comprises the following steps of pre-emulsifying monomers, carrying out seed polymerization, continuous drop adding reaction as well as elimination reaction, adjusting pH value and viscosity, using a filter screen to filter the monomers and discharging after the monomers are qualified. Under the existence of suitable reactive emulsifier, the invention successfully synthesizes the soap-free copolymerized self-crosslinking emulsion which has high stability and transparency, excellent performance in coating temperature resistance, freezing resistance, damp-heat resistance, aging resistance and other aspects, and completely meets the requirements of the printing-packaging industry.

Description

technical field [0001] The invention relates to an adhesive used in the printing and packaging industry, in particular to a water-based adhesive used in the film coating process of the packaging industry. Background technique [0002] At present, the adhesives used in the laminating process of the printing and packaging industry are generally solvent-based. Due to a large amount of organic solvents being discharged into the atmosphere, serious environmental damage is caused. At the same time, the production environment is quite harsh and there are great potential safety hazards. Fortunately, we have deeply realized the seriousness of the problem, so the development of water-based laminating adhesive is of great significance to environmental protection, resource conservation, reduction of production costs, and creation of a harmonious society. [0003] However, there are certain problems in the water-based film adhesives currently on the market, which are mainly manifested in...
