The invention relates to a method for synthesizing high-purity polysorbate-80. The polysorbate-80 (I) is a partial esterified product of a sorbitan ethyoxyl compound and oleic acid. The method comprises the following steps of: (1) partially dehydrating sorbitol as a raw material under the action of an acid catalyst in a state of vacuum to obtain sorbitan (II); (2) carrying out addition polymerization on the sorbitan (II) and oxirane under the action of a base catalyst to obtain sorbitan polyethenoxy ether (III), wherein the addition number of the oxirane is 20; (3) reacting the sorbitan polyethenoxy ether (III) with the high-purity oleic acid under the action of an esterifying catalyst and refining to obtain the high-purity polysorbate-80. The invention leads the emulsifying and solubilizing performance of products to be more perfect and the quality of the products to easily meet the requirement of an injection class and has easily controlled quality and good stability; and the high-purity polysorbate-80 has lower blood dissolving rate in same concentration, and predictable and safer clinical use by being used as an auxiliary material for injection.

The invention discloses a method for making a base asphalt warm-mix rejuvenator. The method comprises: 1) adding sodium α-alkenyl sulfonate into water and stirring until the sodium α-alkenyl sulfonate is completely dissolved to obtain a solution; 2) Add 80-type polysorbate and triethanolamine to solution A, and use a high-speed shearing machine at a speed of 2000r / min to shear until mixed evenly to obtain solution B; 3) Add RA‑2 regeneration agent to solution B, And use a high-speed shearing machine to shear at a speed of 3000r / min until the mixture is evenly mixed, and the obtained product is the base asphalt warm mix rejuvenator. The beneficial technical effects of the present invention are: a method for making matrix asphalt warm-mix rejuvenator is proposed, and the prepared matrix asphalt warm-mix rejuvenator can recover and regenerate the performance of aged matrix asphalt under warm-mix conditions, which can effectively reduce production Energy consumption and pollution in the process.

The invention discloses a universal environment-friendly anti-freezing solution for vehicles, which is characterized by comprising the following components in parts by weight: 10-15 parts of ethylene glycol at dacron grade, 6-8 parts of sodium stannate, 2-3 parts of alizarin red, 5-10 parts of potassium hydroxide, 0.1-0.5 part of dodecyl dimethyl benzyl ammonium chloride, 3-5 parts of borax, 5-10 parts of a non-ionic emulsifier, 3-5 parts of polysorbate, and 10-15 parts of water.

The invention discloses ink, comprising 20-35 parts of ink base, 5-10 parts of adsorbent, 0.01-0.05 part of polysorbate-80, 20-30 parts of reducer, 5-10 parts of titanate coupling agent, 5-10 parts of dispersant, and 1-5 parts of metal paste. The metal paste is silver or gold paste, the ink base is at least one of green ink, yellow ink, golden red ink or deep blue ink. Polysorbate-80 forms a protective layer on the surface of metal powder and adsorbent to be attracted with adsorbent with the polar group. A great deal of adsorbent contacts and is combined with the surface of the metal powder. The titanate coupling agent is of long-chain structure, epoxy resin is of three-dimensional mesh structure, and the polysorbate-80, the titanate coupling agent and the epoxy resin are made up of a special brightness enhancement film after ultrasonic treatment. Therefore, ink brightness after added with metal powder is increase by more than 20%. The more stable structure is formed under the combined action of the epoxy and the titanate coupling agent, so that ink can be kept in bright color for a long time.
