| titleOfInvention | Ultralow-ammonia concentrated natural latex and preparation method thereof |
| abstract | The invention discloses a preparation method of ultralow-ammonia concentrated natural latex, which comprises the following steps: s1, collecting fresh latex, and pretreating; s2, adding ammonia, a sterilizing and fresh-keeping agent and phosphate, adjusting the mass fraction of the ammonia to be 0.15-0.25%, uniformly stirring, clarifying for 8-72 hours, and removing sediments; s3, transferring the clarified latex to a centrifuge for centrifugation, separating out skim latex and concentrated latex, transferring the concentrated latex to an adjusting tank, immediately adding the sterilizing preservative and lauric soap, fully and uniformly stirring, and performing concentrated latex accumulation to obtain concentrated latex; s4, adjusting the dry glue content in the concentrated latex. The preparation method of the ultralow-ammonia concentrated natural latex provided by the invention not only can play a role in sterilization and bacteriostasis for a long time, ensures that the latex properties are more stable, but also can reduce the using amount of ammonia, is non-irritant and environment-friendly, has a small using amount, and saves the cost. |
