Preparation method of modified moisture-curable polyurethane hot melt adhesive
ActiveCN105255434AStripping strong and excellentEasy constructionPolyureas/polyurethane adhesivesAdhesive cementPolymer science
The invention discloses a preparation method of a modified moisture-curable polyurethane hot melt adhesive and belongs to the technical field of synthesis of polyurethane adhesives. The preparation method of the modified moisture-curable polyurethane hot melt adhesive has the innovations that pentaerythritol diacrylate is applied for modifying the traditional moisture-curable polyurethane hot melt adhesive, the pentaerythritol diacrylate can serve as a chain extender as two hydroxyls are contained, usage amount of the pentaerythritol diacrylate is regulated, viscosity of a target product is controlled to be in a reasonable range, so that the pentaerythritol diacrylate is convenient for construction and has satisfactory initial adhesion; and meanwhile, the pentaerythritol diacrylate modifier contains a short branched chain functional group acrylate, so that final peeling strength of the target product is also better than that of the traditional conventional product.

Method for preparing alkyd resin using illegal cooking oil
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.
