Abstract

The invention discloses an epoxy linseed oil and citric acid compound plasticizer. The epoxy linseed oil and citric acid compound plasticizer is characterized by comprising citric acid, n-butyl alcohol, sulfuric acid, linseed oil, petroleum ether, formic acid, hydrogen peroxide, catalyst, sodium hydroxide solution, acetic acid and acetic anhydride, wherein the weight part ratio of the citric acid, the n-butyl alcohol and the sulfuric acid is 1 to (1 to 2) to 0.01; the molar ratio of the citric acid and the acetic anhydride is 1 to 2.5; the mass part ratio of the linseed oil, the petroleum ether, the formic acid, the hydrogen peroxide and the catalyst is 10 to 3 to 5 to 13 to (0.2 to 0.6); the molar ratio of the linseed oil, the sodium hydroxide solution and the acetic acid is 1 to (0.5 to 1.5) to (1 to 3). The epoxy linseed oil and citric acid compound plasticizer has the advantages that by adopting ether bonds, compared with traditional citric easters plasticizer, the compatibility is better, and the easiness in separation is avoided; by combining epoxy linseed oil and citric easters compound plasticizer, the property is excellent.

Description

technical field [0001] The invention relates to a plasticizer, in particular to a composite plasticizer. Background technique [0002] With the rapid development of the plastics industry and the textile printing and dyeing industry, the amount of plasticizers has increased significantly. Now the more commonly used plasticizers in the market are phthalates. In recent years, people have paid attention to health and carried out research on traditional phthalate plasticizers, and found that phthalates increase Plastics can pollute air, water, soil, and even food, and degrade very slowly in the environment, so they have become global environmental pollutants that have attracted much attention. In addition, in daily life, people are in direct contact with plastic products, and phthalate plasticizers will enter the human body through various channels and cause different degrees of harm. Epoxy plasticizer is a new type of non-toxic plasticizer that has been successfully developed ...
