The invention belongs to the technical field of coatings, and concretely relates to a low-VOC automobile varnish and a preparation method thereof. The low-VOC automobile varnish is prepared by mixinga component A with a component B according to a weight ratio of 1:1; the component A comprises 78-84% of polyol resin synthesized by using hydroxybutyl acrylate as a hydroxy monomer, 3-7% of hyperbranched polyester polyol resin, 3-6% of a nano-silica oily liquid, 4-8% of ethyl 3-ethoxypropionate, 2-6% of dimethyl nylon acid, 0.1-0.6% of a leveling agent and 0.01-0.06% of an organotin drier; and the component B includes 74-84% of a curing agent and 16-26% of a solvent. The varnish has a construction viscosity of 20 s / 25 DEG C (Tu-4 cup) or less and a construction solid content of 80% or above,meets the requirement of the VOC content being equal to or less than 200 g / L during construction, and also has the advantages of simple formula, low cost, and high performances of a paint film.

The invention discloses a process for producing osmanthus fragrans Chinese pear fruit wine, which belongs to the field of agriculture product machining. The wine is made by fermenting Chinese pear and osmanthus fragrans as main materials, the sour and sweet fruit taste of the Chinese pear, the sweet fragrance of the osmanthus fragrans, and the healthcare effects of the two materials are retained. The invention mainly focuses on research on novel fruit wine which is made by mixing and fermenting the Chinese pear and the osmanthus fragrans. The process comprises the following steps: juicing fresh Chinese pear as a raw material, wherein the ratio of juice to water is 1:(0.5-1.5), adding 3-5g of dried golden osmanthus fragrans into each liter of the fermentation liquid, subsequently inoculating activated grape wine high-activity yeast to brew the osmanthus fragrans Chinese pear fruit wine, wherein the fermentation condition is that the fermentation period is 6-8 days, the main fermentation temperature is 18-22 DEG C, the initial adjusted sugar degree is 20-22%, the initial pH value is 4.0-4.5, and the yeast inoculation amount is 6-10%, and the alcoholic strength of a fruit wine finished product brewed under such conditions is about 10-11% (v / v), and the wine is pure and gentle in taste, transparent and clear in color, thick and long-lasting in fragrance, thick in fruit fragrance and soft and tender in wine fragrance.

A nano-transparent iron oxide inkjet color paste, which is composed of iron oxide, dispersant, pH regulator, bactericide and water, calculated in parts by weight of raw materials: 30-35 parts of iron oxide; 15-20 parts of dispersant; pH 0.4~0.6 parts of conditioner; 0.2~0.4 parts of bactericide; 45~55 parts of water; the invention adopts new processing technology and equipment and optimized color paste formula, the particle size of color paste can reach nanometer level, good storage stability, color paste It adopts a resin-free system and solvent-free components, which is environmentally friendly and can be widely used in various types of inkjet coatings.

The invention discloses a method for improving the non-bio-stability of medicated wine and is characterized in that: the intermediate half-finished medicated wine is heated to make an increasing temperature and aging treatment, then is heated up to between 80 DEG C and 85 DEG C and maintained for five to eight minutes, then is made a temperature drop up to between 45 DEG C and 49 DEG C and maintained for four to six days; the medicated wine with the method apparently improves the non-bio-stability, has no solids to be precipitated even if under lower temperature, and can keep good clarification.

The invention belongs to the technical field of coatings and particularly relates to weather-resistant automobile repair varnish and a preparation method thereof. The varnish is prepared from a component A and a component B in the weight ratio being 2:1 through mixing. The component A comprises raw materials in percentage by mass as follows: 10%-20% of chlorotrifluoroethylene / vinyl ether copolymerization resin, 58%-68% of fluorine modified hydroxyl acrylic acid, 17%-27% of a solvent A, 0.1%-0.6% of a leveling agent and 0.01%-0.05% of an organic tin drier; the component B comprises raw materials in percentage by mass as follows: 30%-40% of a hexamethylene diisocyanate trimer and 60%-70% of a solvent B. A film formed by the weather-resistant automobile repair varnish is flat and smooth, hasexcellent adhesion, hardness and other properties, has excellent weather resistance, is not prone to pulverization after being subjected to Q-UVB artificial accelerated aging for 5,000 h, has the gloss loss rate of 15% or below and the chromatic aberration delta E of 3 or below and has good application effects.
