Abstract

The invention provides a novel low-temperature cold-chain quaternary ammonium salt disinfectant and a preparation method thereof. The disinfectant is prepared from the following raw materials: a compound quaternary ammonium salt, a guanidine disinfectant, a compound anti-freezing synergist, a humectant, an inert auxiliary agent and water. The disinfectant solves the problem that the disinfection effect of an existing disinfectant is weakened and attenuated under the freezing condition, the novel low-temperature cold-chain quaternary ammonium salt adopts a low-temperature-resistant anti-freezing technology, is safe, environmentally friendly, actually non-toxic, colorless, transparent and free of pungent smell, and does not form ice crystals and ice ballasts under the low-temperature condition of -20 DEG C, the product meets the definition of low temperature in national standards, industrial standards and local standards, and the technology also has strong permeability to frost on the surface layer of a frozen object, so that the disinfection effect is optimal, and the object surface environment is thoroughly disinfected in a low-temperature freezing special condition environment.

Description

technical field [0001] The invention belongs to the technical field of disinfection products, in particular to a novel low-temperature cold-chain quaternary ammonium salt disinfectant and a preparation method thereof. Background technique [0002] At present, there is no special disinfectant on the market that can directly disinfect surfaces and environments under low-temperature freezing conditions. According to the local standard DB 12 / T 557-2015 of cold chain logistics and cold storage technical specifications; according to "JB / T9061- 1999 Combination Cold Storage "Standard, according to cold storage temperature is divided into (freezing, cold storage): high temperature: -2 ℃ ~ 12 ℃; medium temperature: -10 ℃ ~ 2 ℃; low temperature: -20 ℃ ~ -10 ℃; freezing: -30 ℃~-20℃, according to "GB / T28577 Cold Chain Logistics Classification and Basic Requirements" Cold Chain Logistics Classification - Classification by Temperature Application Range Frozen logistics: applicable tempera...
