Problems solved by technology

White emulsion is a water-based glue with slow drying speed and poor adhesion to PP and PE plastic bases; ordinary solvent glue has a faster drying speed and better adhesion to PE and PP plastic bases, but it still cannot fully satisfy paper Requirements for the bonding fastness between the cylinder and the plastic base
Now, one tube with multiple shells, that is, one paper tube is filled with multiple shells, which are fired one by one according to the program, has become a mainstream product. The adhesive layer between the paper tube and the base needs to withstand multiple impact loads. The existing adhesives cannot guarantee the safety of fireworks. quality

Abstract

The invention relates to a nano-modified firework holder adhesive and the preparation method thereof. The nano-modified firework holder adhesive is prepared from SBS elastomer as main body material, environment-friendly solvent, nanomaterial, tackifying resin and stabilizer by dissolving and mixing. The product meets the Chinese environmental standard, and can increase the bonding strength between paper tube and the holder of fireworks. The nano-modified firework holder adhesive has the advantages of reasonable and scientific formulation and simple production process.

Description

technical field [0001] The invention relates to a nano-modified firecracker base adhesive and a preparation method thereof, in particular to a nano-modified SBS adhesive used for bonding between a firecracker barrel and a base and a preparation method thereof. Background technique [0002] The small cannonballs, fireworks and potted flowers in the fireworks series products are all filled with propellants into paper tubes, and then the paper tubes are fixed on the base, so that they can be set off on the ground smoothly, without shaking or tilting due to impact and vibration. It can rise straight to the sky to form a colorful and beautiful picture. The firecracker base glue mainly plays the role of bonding the paper tube and the base. [0003] With the continuous progress of the fireworks industry, the materials of the fireworks base are also varied, including artificial wood chip bases, cardboard bases, and PP and PE plastic bases that are difficult to stick. The paper tub...
