[0033] The preparation process of solvent-based rubber pressure-sensitive adhesive: (1) Plasticize natural and styrene-butadiene rubber on a rubber mixer, and then add anti-aging agent, tackifier, vulcanizing agent, etc. in turn for mixing. (2) Place the kn...
Embodiment 2
[0039] Embodiment 2: The manufacturing method of environment-friendly pressure-sensitive adhesive material mainly consists of the following steps:
[0040] The first step: first make solvent-based polyacrylate pressure-sensitive adhesive, the raw materials are: butyl acrylate (BA), methyl methacrylate (MMA), acrylic acid (AA), vinyl acetate (VAc), hydroxyethyl acrylate Esters, ethyl acetate, azobisisobutyronitrile, chain transfer agent dodecanethiol. The polymerization process is as follows: in a 500ml four-necked flask equipped with an electric stirrer, a reflux condenser, a thermometer and a dropping funnel, put all the monomers and solvents, and feed N 2 ; When the temperature rises to 80°C, the initiator azobisisobutyronitrile solution is added dropwise in batches, the reaction is kept for 6 hours, and the temperature is lowered to 50°C to obtain a solvent-based polyacrylate pressure-sensitive adhesive.
[0041] Step 2: In a closed environment, heat the solvent-based poly...
Embodiment 3
[0047]Embodiment three: the manufacture method of environment-friendly pressure-sensitive adhesive material, mainly is made up of following steps:
[0048] The first step: first make solvent-based polyacrylate pressure-sensitive adhesive, the raw materials are: butyl acrylate (BA), vinyl acetate, 2-ethylhexyl acrylate, hydroxyethyl acrylate, acrylic acid, toluene, ethyl acetate ester. The polymerization process is as follows: put monomers such as butyl acrylate, toluene, and ethyl acetate into a four-necked flask equipped with a reflux condenser, a thermometer, an air guide tube and a stirrer, and add the initiator cumene peroxidation dropwise when the reflux temperature is reached. Hydrogen, the time is two hours, continue to react for three hours, then add the initiator cumene hydroperoxide dropwise, continue to react for about two hours to obtain a colorless transparent viscous liquid.
[0049] Step 2: In a closed environment, heat the solvent-based polyacrylate pressure-s...
