Discussion on Environmental Modification of Solvent-free Environmental Alkyd Resin

1. natural vegetable oils and fats overview:

natural vegetable oils are fatty acid triglycerides. The fatty acids that make up vegetable oil molecules mainly include oleic acid with one double bond, linoleic acid with two double bonds and linolenic acid with three double bonds, in addition to palmitic acid, stearic acid, ricinoleic acid, erucic acid, etc. These raw materials can be extracted from linseed oil, hemp oil, suzi oil, tung oil, catalpa oil, walnut oil, soybean oil, safflower oil, sunflower oil and other natural oils and other natural oils. Triglyceride is a very important substance, which can be synthesized from different monomers. These monomers can form polymers with excellent properties after a series of chemical reactions such as polyaddition, polycondensation, esterification, etc. It is used to manufacture various raw materials to meet industrial needs.

2.

ultra-long oil alkyd resin is a linear resin with linear polyester as the main chain and fatty acid group as the side chain, which is generated by polycondensation modification reaction of polyol, polybasic acid and fatty acid (vegetable oil). it is a modified vegetable oil with polar as the main chain and non-polar as the side chain. when the oil degree (oil content) of alkyd resin increases, I .e. the fatty acid side chain content of resin increases, the polarity of resin molecules decreases, molecular weight decreases and viscosity decreases, the improved solubility can improve the solubility of the resin in a hydrocarbon solvent. In terms of resin properties, alkyd resin oil content (oil content) increased, the drying time of the coating film was shortened, and the flexibility was improved, but the hardness and mechanical properties of the coating film (such as scratch resistance, abrasion resistance, impact strength, etc.) decreased.

super long oil alkyd resin is a kind of environmental protection modified oil, lower than the polymer oil odor, high molecular weight, fast drying, good film forming, high hardness, good yellowing resistance, is a kind of high solid content of natural environment-friendly fine chemical raw materials used in the coating ink industry, it can be used in the fields of clear oil paint, varnish paint, enamel paint, gold paint, wood wax oil, wood oil, modified paint (wide paint), paint paste, anti-corrosion and anti-rust paint, road marking paint, insulating paint, offset printing ink, quick printing integrated machine ink, vegetable oil natural environment-friendly lubricant, cylinder sealing grease, water-based phase transfer emulsion paint, oil paint, etc.
