Problems solved by technology

[0002] In the field of membrane structural materials used in the construction industry, B-type 3-micron glass fiber single yarn is usually used as the basic material in the world. The strength far exceeds the strength ratio of steel, but this B-type 3-micron glass fiber single yarn has extremely high technical content, low output, and high price. There are only three manufacturers in the world, and most of the products are used in the military industry. Membrane structure materials in the industry are difficult to supply on demand, and the price is unacceptably high
There is a kind of E-type 5.5-7 micron glass fiber yarn made in China, which is cheap and has sufficient supply, but its single yarn weight ranges from 150 to 680tex, and the tensile strength after it is made into fabric cloth can only reach 1500-3000N / 50mm. The bending fatigue resistance is only 10,000-30,000 times at 25°C. Such performance characteristics cannot meet the physical performance requirements of the membrane structure building as the core substrate. Therefore, the E-type 5.5-7 micron glass fiber yarn as the core substrate The modification process must be carried out. The modification process is to pass the glass fiber yarn wound in the drum through the transmission shaft installed in the treatment agent tank filled with impregnated treatment agent, and then sintered by the drying equipment and then taken up by the winding device. Roll, that is, modified glass fiber yarn, the key of modified glass fiber yarn is the composition of the impregnation treatment agent, which is the topic to be discussed in this case

Embodiment 1

[0019] Prepare 3000 grams of impregnation treatment agent at room temperature: take 2760 grams of the above-mentioned polytetrafluoroethylene diluted emulsion with a solid content of 30%, and then add 150 grams of TX-2-30 series emulsifiers and 45 grams of FA-series fluorosurfactants , and then stir for the first time, the stirring speed must not be higher than 90 rpm, too fast to condense, so it is advisable to use 30 to 90 rpm, and the stirring time is preferably 5 to 20 minutes. The stirring speed of this embodiment is 90 rpm, the stirring time is 5-10 minutes, the second stirring is carried out after adding 45 grams of silicone surfactant, the stirring speed and stirring time are the same as before, that is, the dipping treatment for glass fiber yarn modification agent.

Embodiment 2

[0021] Prepare 5000 grams of impregnation treatment agent at normal temperature: get 4700 grams of polytetraoxyethylene dilute emulsion with a solid content of 30%, 200 grams of TX-2-30 series emulsifiers, 25 grams of FA-series fluorosurfactants, and implement The same as Example 1, the first stirring is carried out first, and then the second stirring is carried out after adding 75 grams of silicone surfactants. Impregnation treatment agent for fiber yarn modification.

Embodiment 3

[0023] Prepare 6000 grams of impregnation treatment agent at normal temperature: take 5730 grams of polytetrafluoroethylene diluted emulsion with a solid content of 30%, 180 grams of TX-2-30 series emulsifiers, and 30 grams of FA-series fluorosurfactants, and implement The same as Example 1, the first stirring is carried out first, and then the second stirring is carried out after adding 60 grams of silicone surfactants. The second stirring speed is the same, 30 rpm, and the stirring time is 20 minutes respectively. Impregnation treatment agent for fiber yarn modification.

Abstract

The soaking treatment agent for modification of glass fiber yarn is prepared through diluting marketable fluororesin emulsion of 60 % solid content with deionized water into 10-30 % concentration fluororesin emulsion, and adding TX-2-30 emulsifier, FA fluorous surfactant and silicone in certain proportion through stirring. The soaking treatment agent is used in soaking glass fiber yarn and can raise its performance, especially tensile strength and breaking strength, for meeting the require in film structure building.
