Brightening effect of fluorescent whitening agent in chlorinated paraffin
Chlorinated paraffin is a chlorinated derivative of paraffin hydrocarbon, which has the advantages of low volatility, flame retardancy, good electrical insulation, low cost, etc., and can be used as a flame retardant and a polyvinyl chloride auxiliary plasticizer. Widely used in the production of cable materials, flooring, hoses, artificial leather, rubber and other products. It can also be used as an additive in the production of paints, plastic runways, lubricants, etc. It is a light yellow viscous liquid. How to eliminate the yellow color in the product to make the color of the product clear and transparent? The most effective way is adding fluorescent whitening agent! So what kind of fluorescent whitening agent is suitable for chlorinated paraffin to enhance transparency? This is based on the characteristics of the chlorinated paraffin itself.
The production of chlorinated paraffin is stable. Generally, the metered liquid paraffin is added to the reaction cup, and then the chlorine gas is reacted. After deacidification, the stabilizer is packaged. The processing temperature is around 80 degrees. Although it is deacidified, it is still acidic in the material. Therefore, when selecting the fluorescent whitening agent, the solubility of the organic solvent is better first; secondly, the fluorescence E value is higher, so that the effect of increasing the brightness is good! Finally, it is also resistant to acid, and it has a very good anti-reflection effect under acidic conditions.
Ruiqite Chemical introduced RQT-A-1 upgraded fluorescent whitening agent from Germany's advanced production technology. This brightener has the following advantages:
1, can be effectively dissolved in organic solvents such as benzene, ether and various mineral oils.
2, suitable for normal temperature to 220 degrees processing temperature.
3, light fast and alkali resistant, in the acid chlorinated paraffin with a pH of 4-6, the normal effect can be exerted without affecting the antireflection and brightening.
Ruiqite RQT-A-1 upgraded version of fluorescent whitening agent is adsorbed by activated carbon, the color is light white, the ash is small, the addition amount is small, and the brightening effect is remarkable! Normal addition of 30 to 50 grams of light in a chlorinated paraffin can achieve an unexpected anti-reflection magic effect!
