Abstract

The invention discloses a method for preparing an alkyd resin using illegal cooking oil and belongs to the field of high polymer materials. The method includes the following steps of putting hogwash oil, rosin, glycerol, pentaerythritol, neopentyl glycol, and an accelerant into a reaction still, and performing heating and reaction; cooling acquired reactants, putting terephthalic acid in the reaction still, and performing heating and reaction; heating the reactants, adding a backflow solvent, and performing backflow heat preservation; cooling reactants, adding a petroleum resin, and performing even stirring; diluting an obtained material with a solvent. According to the method for preparing the alkyd resin using the illegal cooking oil, by means of a formulation design of the reclaimed illegal cooking oil and hogwash oil, the alkyd resin with high properties is prepared through synthetic reaction, manufactured antirust paint is excellent in antiseptic property, and ready mixed paint or enamel paint is excellent in weather fastness, glossy, bright-colored, and good in property.

Description

[0001] technical field [0002] The invention discloses a method for preparing alkyd resin from waste oil, which belongs to the field of polymer materials. [0003] Background technique [0004] With the rise of prices, the raw materials of coatings have risen linearly, which has greatly increased the production cost of coatings, especially in steel structure coatings. Steel structure manufacturers have lower and lower cost requirements for steel structure coatings, making it difficult for many coating factories to survive. . The gutter oil discharged from many restaurants and food factories is difficult to deal with, and most of them are discharged into the sewers and flow into rivers and seas, thereby causing certain impacts on the environment. [0005] Contents of the invention [0006] The object of the invention is to: provide a kind of alkyd resin that utilizes waste oil as raw material and produce, reduce its production cost, propose a kind of method that makes ...
