On June 24, 2015, Dai, Liang published a patent.Formula: C17H24N4O6 The title of the patent was Boron carbide filling-modified plastic and preparation method thereof. And the patent contained the following:
Title plastic is composed of LDPE 100, nano antimony tin oxide 4.5-6.8, nano titanium dioxide 1-2, epoxy soybean oil 2-3, stalk ashes 1-3, nano silica 0.4-0.8, trimethoprim lactate 0.1-0.3, barium chromate 0.2-0.4, boron carbide 0.4-0.5, maleic anhydride grafted compatibilizer 1.2-1.6 weight parts, and appropriate amount of dehydrated alc. Title method includes the following steps: calcining nano antimony tin oxide and nano titanium dioxide at 620-810°C for 30-50 min, cooling, placing in a three-neck flask, adding anhydrous ethanol and maleic anhydride grafted compatibilizer, stirring evenly, and heating at reflux for 4-5 h, centrifuging, washing with anhydrous ethanol for 2-3 times, and vacuum drying at 80°C; adding stalk ashes and nano silica to the above product, and mixing evenly to prepare mixed powder; adding low-d. polyethylene to the high-speed mixing and dispersing machine, adding the mixed powder, boron carbide and other remaining ingredients, mixing and dispersing for 15-20 min, pouring into a twin-screw extruder, extruding and granulating. The prepared plastic has improved wear resistance, good heat stability, UV irradiation resistance, aging resistance, high intensity and chem. resistant properties, is deeply processed into plastic film used for green house of vegetables, has short degradation cycle, strong lower temperature resistance, obvious effect of heat insulation, self-cleaning and antibacterial property, and high transmittance. The experimental process involved the reaction of 5-(3,4,5-Trimethoxybenzyl)pyrimidine-2,4-diamine 2-hydroxypropanoate(cas: 23256-42-0).Formula: C17H24N4O6
