News:
days ago, by Hebei Hengshui Xinguang Chemical Co., Ltd. developed the building net taste
coatings
emulsion preparation technology through the Hebei Province Science and Technology Achievement Transformation Service Center organized by the expert identification. Experts believe that the technology is advanced, product performance indicators to reach the technical level of foreign products, with good prospects for promotion.
, as the key material of environmentally friendly clean taste coating, the preparation technology of clean acrylic co-polylactic emulsion greatly affects the quality of the coating. At present, China's high-end building clean taste paint emulsion mostly depends on foreign-funded enterprises, which directly affects the production costs of products. Hengshui New Light Company and Beijing University of Chemical Engineering, Tianjin University School of Chemical Engineering experts around the building clean taste paint emulsion preparation technology to carry out joint research, through innovative process to solve the preparation of clean taste phenyl propylene type
building coatings
emulsion technical bottleneck, product emulsion VOC control within 100ppm, and in color display, mechanical stability, paint film water resistance, alkali resistance and scrub resistance to reach the international advanced level of similar products.
the project technicians through the development of molecular distillation technology to purify the raw material monomer new process, removing non-reactive impurities, thus solving the non-polymer impurities residual in the emulsion caused by the serious irritating odor; Through the development of falling film evaporation technology and hot nitrogen combined process, further remove volatile organic matter in the emulsion, to achieve a true sense of the product's clean taste environmental protection; In addition, they also successfully solved the problem of concentrated stability, mechanical stability and water resistance of the coating film through the preferred reactive emulsion and non-ion emulsion system.
