The invention belongs to the technical field of high molecular materials, and relates to coal-based polymer hydrogel and a preparation method thereof. The preparation method comprises the following steps: firstly, extracting a water-soluble high polymer from low calorific value coal by adopting an alkali dissolving and acid precipitation method; then adjusting the pH (Potential of Hydrogen) valueof a water-soluble high polymer water solution by utilizing an NaOH solution; then carrying out chemical modification on the water-soluble high polymer by utilizing hydrogen peroxide; introducing a peroxide group, capable of initiating polymerization, into the coal; then adding acrylamide, acrylic acid, an initiator and metal ions and polymerizing, wherein after polymerizing, an ion bond by the acrylic acid and the metal ions is formed; finally, immersing obtained hydrogel into a mixed solvent of an organic solvent and water to form a physical cross-linking point by the hydrogel and further improve the strength thereof, so as to obtain the high-strength coal-based polymer hydrogel. According to the coal-based polymer hydrogel and the preparation method thereof, the low calorific value coalis used as a raw material, and has an abundant source, a low price and a high environment-friendly degree; in a polymerizing process, a chemical cross-linking agent is not used, so that the strengthof the hydrogel reaches grade MPa, and an application field of a hydrogel material is widened.

The invention relates to multifunctional compound golden thread Chinese medicinal herb toothpaste, which comprises the following components: 0.1 to 10 percent of golden thread, 0.1 to 10 percent of Chinese gall, 0.1 to 5 percent of mint, 0.1 to 5 percent of wrinkled gianthyssop herb, 0.1 to 2 percent of sweet tea and the balance of toothpaste body materials. A method for preparing the toothpaste comprises the following steps of: crushing golden thread, decocting in water, and taking supernate; decocting Chinese gall in the water, and taking supernate; mixing the two kinds of supernate, cooling, precipitating and filtering; extracting peppermint oil from mint according to a method of steam distillation; extracting wrinkled gianthyssop herb volatile oil from wrinkled gianthyssop herb according to a method of steam distillation; decocting sweet tea in the water, and taking supernate; and adding compound precipitates of golden thread and Chinese gall, the peppermint oil, the wrinkled gianthyssop herb volatile oil and sweet tea extract into a toothpaste body according to a formula ratio, mixing uniformly and filling. The multifunctional compound golden thread Chinese medicinal herb toothpaste has the good effects of clearing heat, resisting bacteria, diminishing inflammation, stopping bleeding, eliminating ozostomia, preventing caries and moth, desensitizing, easing pain and the like, has fragrant and sweet mouthfeel and does not have side effect.

The invention relates to the field of toothpaste and particularly relates to toothpaste and a preparation method thereof. The toothpaste is mainly prepared from folium ilicis chinensis extract, perilla leaf extract, mulberry leaf extract and auxiliary materials, wherein the folium ilicis chinensis extract accounts for 0.1%-1% of the toothpaste in percentage by weight, the perilla leaf extract accounts for 0.1%-1% of the toothpaste in percentage by weight, and the mulberry leaf extract accounts for 0.1%-1% of the toothpaste in percentage by weight. According to the toothpaste provided by the invention, the folium ilicis chinensis extract, perilla leaf extract and mulberry leaf extract are added into the toothpaste for the first time, and the three traditional Chinese medicine extracts are matched in specific proportions to achieve a synergetic enhanced effect, so that the prepared toothpaste has multiple effects of diminishing inflammation, arresting bleeding, refreshing breath and inhibiting oral ulcer. The invention also provides the preparation method of the toothpaste. The preparation method is simple and feasible, and the prepared toothpaste has uniform component distribution and good performance.

The invention relates to the field of livestock rearing, and in particular relates to a micro-ecologic feed and a preparation method thereof. The gosling anti-stress synbiotics and traditional Chinese medicine composition is composed of a micro-ecologic synbiotics feed additive and Chinese herbal medicine additives, wherein the micro-ecologic synbiotics feed additive is composed of the following components in parts by weight: 10-60 parts of micro-ecologic probiotics and 40-90 parts of oligosaccharide, the viable count of bifidobacterium in each gram of the micro-ecologic synbiotics feed additive is 20-45 billion, the micro-ecologic probiotics is a bifidobacterium preparation, the oligosaccharide comprises fructooligosaccharide, xylooligosaccharide, isomalto-oligosaccharide and soybean oligosaccharide, and the micro-ecologic synbiotics feed additive accounts for 1%-2% of the total weight of the gosling anti-stress synbiotics traditional Chinese medicine composition; and the Chinese herbal medicine additives are composed of the following components in parts by weight: 20-35 parts of spina data seeds, 15-25 parts of water lily, 10-20 parts of purple cathoclines, and 10-20 parts of folium isatidis.
