Abstract

The invention discloses a water-based complex membrane sealing rubber and a preparation method thereof. Styrene, ethyl hexyl acrylate, n-butyl acrylate, phenolic resin, VEA emulsion, anionic emulsifier, initiator, water-based chlorinated polypropylene, defoamer, thickener and deionized water are subject to free radical polymerization to obtain a yellowish milky water-based complex membrane sealing rubber. The water-based complex membrane sealing rubber of the invention is prepared from micro-emulsion phenolic resin modified acrylic acid emulsion as a main material and the water-based chlorinated polypropylene and the like as auxiliary materials, is safe and environment-friendly, does not contain benzene solvents, contains acrylic ester plasticizer, and completely can pass through the detection of residual quantity of heavy metals and VOC monomers in foods and drugs. The water-based complex membrane sealing rubber has good initial adhesion, good adhesive force and good mechanical properties such as high bonding strength, good heat resistance and good low temperature resistance, and has high drying speed.

Description

technical field [0001] The invention relates to the field of water-based adhesives, in particular to a glue used for bonding printed colored paper box seals and a preparation method thereof. Background technique [0002] At present, the water-based laminating sealant on the market is mainly made by dissolving phenolic resin in toluene, and then dispersing the resin solution into polyvinyl acetate latex. Since this glue contains a large amount of toluene solvent, it is not true. [0003] The environmentally friendly products cannot be used on food and drug cartons, which limits the scope of use. Other polyvinyl acetate emulsion [0004] The glue contains DOP plasticizer, this kind of plasticizer will slowly penetrate into the surface of the packaging and printing carton, in many industries [0005] are prohibited. Due to the wide application range and large amount of water-based laminating sealant, safe and environmentally friendly water-based laminating sealant has become...
