EcoV: ETM168 was developed for low-gloss coatings where freeze-thaw capability is critical. EcoV: ETM163 is specially synthesized for semi-gloss coatings with excellent gloss and anti-blocking properties. Semi-gloss coatings based on EcoV: ETM163 emulsion show more than double the low Tg pure acrylic emulsion and low Tg styrene acrylic emulsion Performance. According to Wu Xianliang, manufacturers currently using low-Tg styrene-acrylic technology are particularly interested in EcoV: ETM technology. “The manufacturer can also remove the film-forming additives while improving the scrubbing resistance of the coating. Undoubtedly, EcoV: ETM, as a film-forming substance for high-performance interior decoration coatings, is much higher than the performance of styrene-acrylic acid. On November 2, Nanolux, a global window film group under Singapore’s Novomatrix Pte Ltd, announced that its high-tech car film, the global front windshield film SuperLux7 (SPL7) with nano-multilayer coating technology, will be launched in the near future. Launched in Shanghai. As an environmentally friendly car film product that is completely free of metal, the SPL7 thin superconducting heat insulation film has a light transmittance of up to 7%, while the internal reflectance is only ultra-low 5%, and its heat insulation performance is also much better than At present, similar products on the market provide consumers with a perfect solution for heat insulation and clear vision, so that car owners can enjoy a comfortable and safe driving environment regardless of day and night. PMI is a kind of sandwich structure that can withstand the production and processing conditions of sandwich structural parts. The processing temperature is as high as 18℃ and the pressure is as high as 7bar. The elongation at break of HeroPMI structure foam is more than three times higher than that of standard materials. “At minus 55℃, its mechanical elasticity is still comparable to honeycomb structure. “Evonik said. In the sandwich structure, any damage caused by objects thrown on the runway will be clearly visible, which is a safety requirement of the aircraft industry. The Fraunhofer Institute for Material Mechanics in Germany has already reviewed this material. Perform fatigue testing. Evonik claims that this fine-pored material can make the production of complex parts easier.

2 Reaction principle Esterification reaction: 1.3 Experimental process 1.3.1 Esterification Take a 1000mL four-necked flask, add a certain amount of mixed xylenol, add quantitative PCl3 to the constant pressure dropping funnel, and heat the xylenol in a water bath. Turn on the stirring, evacuate, and add PCl3 dropwise at a certain speed to control the reaction temperature. After the dropwise addition is completed, continue to stir for 30 minutes to complete the reaction. According to the orthogonal experiment and various factors, we set the raw material ratio as: Xylenol: Phosphorus trichloride (mol ratio) = 1:1.1, the dropping rate is 2 drops/s, and the reaction temperature is 50~80℃ . 1.3.2 After the chlorinated esterification reaction is completed, continue to pass chlorine into the reaction flask, adjust the chlorine flow meter, control the chlorine flow rate, and make the reaction proceed normally. The reaction temperature is controlled below 70°C until the reaction is complete.
