High-performance industrial composite glycerin and preparation method thereof

Abstract

The invention discloses a high-performance industrial composite glycerin. The high-performance industrial composite glycerin comprises the following raw materials by weight: 55-65 parts of glycerin, 10-20 parts of an alloy assistant liquid, 3-7 parts of Si powder, 5-15 parts of a reinforcing agent and 2-6 parts of rutile type nano-titanium dioxide. According to the invention, the alloy assistant liquid is added into glycerin to improve the adaptability of glycerin at a high temperature and adapt to the temperature change so as to reach a yellowing-resistant effect, the alloy assistant liquid adopts methyl phenyl silicone oil as a matrix liquid, methyl phenyl silicone oil itself has weather resistance, heat resistance, chemical resistance and other excellent properties, and by adding nickelpowder, titanium carbide powder and magnesium borate powder, on the one hand, methyl phenyl silicone oil can serve as bridging liquid to make nickel powder, titanium carbide powder and magnesium borate powder better integrate into glycerin, the nickel powder can play a repairing role, so that glycerin can adapt to the temperature timely at the high temperature, the yellowing resistance effect isimproved, and the titanium carbide powder and magnesium borate powder can improve the temperature resistant effect of glycerin.

Description

technical field [0001] The invention relates to the technical field of glycerin, in particular to a high-performance industrial compound glycerin and a preparation method thereof. Background technique [0002] Glycerol is a colorless, sweet, clear, viscous liquid. Odorless. Has a warm sweet taste. Commonly known as glycerin, it absorbs moisture from the air, as well as hydrogen sulfide, hydrogen cyanide, and sulfur dioxide. Insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether and oils. The relative density is 1.26362. The melting point is 17.8°C. The boiling point is 290.0°C. The refractive index is 1.4746. The industrial production methods of glycerin can be divided into two categories: the method of using natural oil as raw material, the obtained glycerin is commonly known as natural glycerin; the synthesis method of propylene as raw material, the obtained glycerin is commonly known as synthetic glycerin.

Problems solved by technology

[0003] Existing glycerol has poor anti-yellowing performance at high temperatures, which limits the application field of glycerin. The existing Chinese patent document announcement number: CN1106833317B discloses a kind of high-temperature anti-yellowing glycerin. Its preparation method is as follows: a, take an appropriate amount of purity: 95%-98% glycerin; b, adding appropriate amount of sodium hypochlorite and additives to the above-mentioned glycerin, and stirring evenly under heating conditions to make high-temperature anti-yellowing glycerin; the weight percentage of the above-mentioned raw materials in the whole high-temperature anti-yellowing glycerin is : Glycerin: 90%-99%; Sodium hypochlorite: 1%-1.5%; Additives: remaining

The additive includes any one of the following raw materials or combinations: nano-titanium dioxide, hexamethylphosphoric acid triamide, bis(stearyl) alcohol thiodipropionate, water, and anti-yellowing glycerol is given in this document, However, the raw material is composed of a simple combination of antioxidants, high melting point solvents, and nano-titanium dioxide. The raw materials are relatively conventional, and the combination effect is poor, and further improvement is still needed.
