CN101659854A - Ultralow-temperature glass antifogging anti-frosting antifreeze agent - Google Patents

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

Ultralow-temperature glass antifogging anti-frosting antifreeze agent

One, technical field

A kind of prescription of ultralow-temperature glass antifogging anti-frosting antifreeze agent and manufacturing process technology.

Two, background technology

Existing many about the patented technology of glass anti-fog frost-prevention agent, but anti-fog effect of the high temperature that with regard to the temperature range of its anti-fog and antifrost, has or low temperature good antifogging effect, difference is very big, in view of the difference of each department temperature different with working conditions, the technology that can adapt to the very low temperature service requirements is less relatively, technology as Chinese patent notification number CN1045409 can only guarantee 36～72 hours effectively under 4～65 ℃ of conditions, the technology of CN1069996 can only be used in temperature more than-10 ℃.The technology of CN1092797 also can only be operated in-30 ℃ of anti-fog and antifrost needs that can not satisfy vehicle glass under the northern China winter severe cold condition, and therefore improved necessity arranged.

Three, summary of the invention

The objective of the invention is to invent a kind of ultralow-temperature glass antifogging anti-frosting antifreeze agent that can under condition of ultralow temperature, still can guarantee the needs that vehicle glass can anti-fog and antifrost, the objective of the invention is to realize that by the low temperature frost resistance of improving product its prescription is: (weight %)

1. tween-80 100% 2. Virahols 100% 3. propylene glycol 5%

4.10% sodium lauryl sulfate, 10% 5. monobutyl ethers 8%

6. glycol ether 8% 7. water 40%

The manufacturing process technology of this ultralow-temperature glass antifogging anti-frosting antifreeze agent is as follows:

Earlier 1, No. 2 material being added container mixes, and then add No. 3 the material mix A liquid, then No. 4 material are slowly added A liquid, the limit edged stirs and makes it become B liquid, then successively 5,6, No. 7 material are added B liquid one by one, whenever must after stirring, add the next one again after adding one, it be mixed by quick stirring, add at last 40% water diluted mixture evenly just finished product.

Advantage of the present invention:

1. this product is a water soluble fluid, and non-pollutant discharge is produced safe in utilization.

Through this product smear glass surface cleaning, light, transparency is good, antistatic is not covered with dust.

3. smear the glass antifogging anti excellent performance through this product, do not freeze under-85 ℃ of conditions ,-50 ℃ of following anti-fog performances are good.

4. good fluidity when this product uses, the air-dry speed of film forming is fast, and film forming is antifog to be insisted on for a long time, can keep antifog antifreeze power constant in three months.

Four, embodiment

Identical in the prescription of product of the present invention and the manufacturing process and top three, in manufacturing processed mixed stream and add water temperature should keep being no more than 20 ℃ and be advisable.

Claims (2)
