example 1

[0028] Take 10g of functional additive AMP-95, 10g of emulsifier dioctyl sodium sulfosuccinate, stir and mix at 300-400r / min to obtain a wetting agent, take 400g of polyacrylate emulsion and put it into a stirring tank. At 40°C, stir at 100r / min for 10min, then add 0.2g of defoamer, 100g of rosin terpene resin emulsion, 150g of self-crosslinking emulsion, and continue stirring for 20min to obtain a premix. Take 50g of natural rubber latex and 75g of water-based SBS emulsion , add 0.2g defoamer to the premix, stir at 100r / min for 10min at 40°C, then add 1g wetting agent, 1g preservative, stir at 200r / min for 30min to obtain a composite emulsion, at 40°C Add ammonia water with a mass fraction of 10% to the composite emulsion, and continue to stir until the pH of the composite emulsion reaches 7.0, and adjust the viscosity to 8000mPa·s. After mixing evenly, filter it with a 100-mesh filter, and pack it out to obtain a water-based environmentally friendly sealing glue.

Abstract

Belonging to the technical field of encapsulation, the invention relates to a water-based environment-friendly sealing adhesive and a preparation method thereof. According to a polymer alloyage designconcept, a polyacrylate emulsion, a rosin terpene resin emulsion, a self-crosslinking emulsion, natural latex and a water-based SBS emulsion are blended, because of the action of mechanical shearingforce, chain breaking occur to parts of high polymers, then grafting or blocking, also or group and chain segment exchange can be carried out so as to form the water-based environment-friendly sealingadhesive between polymers, the characteristics of different macromolecules can be optimally combined, thus significantly improving the material performance, or endowing the material with originally absent performance, and different macromolecular polymers that are thermodynamically incompatible can be compounded compatibly, thus obtaining the novel sealing adhesive with the advantages of all thepolymers.

Description

technical field [0001] The invention relates to a water-based environment-friendly sealing glue and a preparation method thereof, belonging to the technical field of packaging. Background technique [0002] BOPP film, its full name is oriented stretched polyene film, which is a film obtained by flow-through, vertical and horizontal stretching and heat setting of polyolefin resin. Compared with BOPP film, there is still a big gap in terms of scale and variety, such as the BOPP of an oil giant. The film has reached 200,000 tons, 50 varieties, and a wide range of applications. At present, BOPP films are developing in a small scale, with a single variety and rough products. In some high-end fields, most of the BOPP film products are imported from abroad, so It needs the strength of big products, increasing the variety of BOPP film, improving the quality, and gradually narrowing the gap with foreign products. BOPP film, known as the queen of packaging, has the characteristics of...
