The water-based ink is prepared from the following raw materials in parts by weight: 28-35 parts of acrylic resin, 10-20 parts of epoxy resin, 12-20 parts of a pigment, 6-12 parts of wollastonite powder, 2-7 parts of nano bentonite, 4-9 parts of a sterilization mildew-proof agent, 0.5-3 parts of epoxy soybean oil, 1-4 parts of polyurethane, 0.5-2 parts of a surfactant, 0.5-2 parts of silane and 26-38 parts of de-ionized water. According to the water-based ink provided by the invention, the wollastonite powder is added so that the wearing resistance and anti-adhesion property of the ink can be improved; the added sterilization mildew-proof agent is prepared from Chinese herbal medicine ingredients, is safe and environment-friendly and has no injuries to health of human bodies; the ink provided by the invention has stable performance, good glossiness and dispersity and high drying speed; and in a utilization process, the ink does not fall off and is not faded, and the printing effect is lasting.

The present invention discloses a preparation method for o-phenyl phenoxyethyl acrylate. The method comprises that: 2-(2-biphenylyloxy)ethanol and acrylic acid are subjected to an esterification reaction under the protection of nitrogen by adopting cyclohexane as a solvent and adopting an organic acid as a catalyst in the presence of a polymerization inhibitor and a reduction agent; and after completing the esterification reaction, alkali washing, water washing drying and reduced pressure solvent removing are adopted to obtain the o-phenyl phenoxyethyl acrylate, wherein the amount of the reduction agent is 0.1-2 wt% of the total weight of 2-(2-biphenylyloxy)ethanol and acrylic acid. The method has characteristics of low reaction temperature and simple process, and can be provided for preparing the low chromaticity, even colorless and transparent aromatic ring-containing acrylate.

A synthetic insulation material that rivals and surpasses down in performance without suffering degradation in insulating power over time. The material is an aggregate of particulate units that have a fractal-like geometric configuration. The geometric configuration includes non-integer dimensionality that promotes physical entanglements of the particulate units. The physical entanglements impart a high frictional resistance to slippage of the particulate units to maintain loft over time by inhibiting the settling of particulate units upon compression. The geometric configuration further includes aspects of self-similarity. The particulate units are formed from a material that efficiently scatters thermal radiation. The combination of high loft and efficient scattering of thermal radiation minimizes heat loss resulting from conduction and radiation, leads to a superior material for thermal insulation, has excellent health characteristics for human and the environment, and exhibits excellent long term life cycle performance.

The invention relates to a compound chitosan preparation, which contains 80-95 parts by weight of chitosan and 5-20 parts by weight of propolis as raw materials. The present invention adopts the combination of chitosan and propolis with high density, low molecular weight and high degree of deacetylation, which has the characteristics of double synergistic effect, makes the human body absorb quickly and has high absorption utilization, and can reduce blood fat, blood viscosity, blood sugar, Lowering cholesterol, protecting the liver, kidney, stomach, inhibiting tumors and other aspects play a better role.

The present invention discloses a buckwheat cake. The buckwheat cake is characterized by comprising the following components in parts by weight: 25-30 parts of buckwheat flour, 35-40 parts of wheat flour, 21-25 parts of sugar powder, 10-15 parts of water, 30-35 parts of rapeseed oil, 0.4-0.8 part of soda, 0.2-0.5 part of baking powder, 0.15-0.2 part of edible alkali, 2-3 parts of an aluminum-freeswelling agent for deep-fried dough sticks, 0.03-0.05 part of sorbitol, 3-5 parts of cerealose, 0.001-0.003 part of calcium propionate, 0.001-0.003 part of sodium dehydroacetate, 10-20 parts of candied wax gourds, 60-120 parts of white sugar, 10-15 parts of honey, 20-35 parts of lard, 5-30 parts of cooked powder and a filling. The aluminum-free swelling agent for the deep-fried dough sticks comprises the following main components: sodium hydrogencarbonate, sodium dihydrogen phosphate, calcium carbonate, monoglyceride fatty acid, citric acid, malic acid, disodium dihydrogen pyrophosphate and xylanase. The buckwheat cake has the following advantages: the buckwheat cake is free of aluminum additives and pigments, does not damage human body health, has better mouthfeel, color and luster, crispness and softness than those of buckwheat cakes containing the aluminum additives, enables consumers to feel assured, and is in line with national standards.

The invention discloses a preparation method of low chroma o-phenyl phenoxyethyl acrylic ester. The method taking cyclohexane as a solvent and organic acid as a catalyst comprises the following steps: carrying out esterification reaction on 2-(2-biphenyl) ethanol and acrylic acid under the protection of nitrogen in the presence of a polymerization inhibitor and a decolorising agent; and after esterification reaction, alkali-washing, water-washing, drying and decompressing to remove cyclohexane to obtain the low chroma o-phenyl phenoxyethyl acrylic ester. The use level of the decolorising agent is 1-3wt% of the total weight of 2-(2-biphenyl) ethanol and acrylic acid. The method disclosed by the invention is low in reaction temperature and simple in process, and can be used for preparing low chroma or even colorless and transparent aromatic-ring-containing acrylic ester.
