High/low-temperature multifunctional long-lifespan high-performance glass antifogging agent

Abstract

The invention relates to a glass antifogging agent, in particular to a formulation and a manufacturing technique for a high/low-temperature multifunctional long-lifespan high-performance glass antifogging agent. The formulation is characterized by comprising the following components (in percentage by weight): 1, 3 to 30 percent of gelatin; 2, 50 to 69 percent of phosphoric acid; 3, 20 to 30 percent of isopropanol; 4, 0 to 10 percent of formaldehyde; 5, 0 to 10 percent of glycerol; and 6, 0 to 19 percent of ethylene glycol. The manufacturing technique comprises the following steps: adding materials 2 and 3 to a container and evenly stirring to form solvent A; putting a material 1, namely the gelatin, into the solvent A and allowing the gelatin to absorb enough solvent A to swell, be completely soft and have no hard heart; slowing heating the gelatin during water bath to dissolve the gelatin; using a stirrer to continuously stir the gelatin at a speed of 50 revolutions per minute till the gelatin is completely dissolved; keeping the constant temperature of gelatin solution and adding materials 4, 5 and 6 in turn pro rata; stirring and mixing evenly; and obtaining a finished product of the antifogging agent. The product can have good antifogging effects in a wide temperature range between 30 DEG C below zero and 100 DEG C.

Description

1. Technical field [0001] A glass anti-fogging agent, especially a composition of a high-low temperature multifunctional long-life high-performance glass anti-fogging agent and its manufacturing technology. 2. Technical Background [0002] At present, the working temperature range of many glass anti-fog film technologies is either high or low, and cannot have a wide temperature range that can work at high and low temperatures. At the same time, the anti-fog time is generally short, and it does not have the requirements of long life and high performance, such as Technologies such as Chinese Patent Announcement No. CN1045409, CN1048052, CN1069996 are all like this, and it is necessary to make changes. 3. Contents of the invention [0003] The purpose of the present invention is to invent a kind of multifunctional and long-life performance of high and low temperature working temperature range is more excellent and comprehensive glass anti-fogging agent, it is made of transpar...
