Ultralow-temperature glass antifogging anti-frosting antifreeze agent

Abstract

The invention provides a formulation and a manufacturing technique for an ultralow-temperature glass antifogging anti-frosting antifreeze agent. The formulation is characterized by comprising the following components (in percentage by weight): 1, 100 percent of Tween-80; 2, 100 percent of isopropanol; 3, 5 percent of propylene glycol; 4, 10 percent of 10 percent lauryl sodium sulfate; 5, 8 percentof mono-butyl ether; 6, 8 percent of diethylene glycol; and 7, 40 percent of water. The manufacturing technique comprises the following steps: adding materials 1 and 2 to a container and mixing the two well; adding a material 3 and evenly mixing to obtain liquid A; slowly adding a material 4 to the liquid A and stirring while adding to obtain liquid B; sequentially adding materials 5, 6 and 7 tothe liquid B, namely adding one material, evenly stirring and then adding the next one; mixing the obtained product well through fast stir; and adding 40 percent of water, diluting and evenly mixing to obtain a finished product. The product which is aqueous solution has the advantages of no toxicity, no pollution, low cost, use convenience, good antifogging anti-frosting effects, capability of notfreezing at 85 DEG C below zero and good antifogging effects at 50 DEG C below zero.

Description

1. Technical field [0001] The invention discloses a formula and manufacturing technology of an anti-fog, anti-frost and anti-freeze agent for ultra-low temperature glass. 2. Background technology [0002] There are many patented technologies on glass anti-fog and anti-frost agents, but in terms of the temperature range of anti-fog and anti-frost, some have good high-temperature anti-fog effects or low-temperature anti-fog effects, which vary greatly. Different from the conditions of use, there are relatively few technologies that can adapt to the requirements of ultra-low temperature use. For example, the technology of Chinese Patent No. CN1045409 can only be guaranteed to be effective for 36-72 hours under the condition of 4-65°C, and the technology of CN1069996 can only be effective at -10°C or above. temperature used. The technology of CN1092797 can only work at -30 ℃ and cannot meet the needs of anti-fog and anti-frost of automobile glass under the winter severe cold co...

AI Technical Summary

Problems solved by technology

The technology of CN1092797 can only work at -30°C and cannot meet the anti-fog and anti-frost needs of automobile glass under the severe winter conditions in northern my country, so there is a need for improvement
