Abstract

The invention relates to a method for preparing plasticizer and lubricant by using semi-drying oil or drying oil, which comprises the steps of: firstly, preparing aliphatic ester by using semi-drying oil or drying oil; secondly, carrying out Diels-Alder addition reaction on 100 parts by weight of aliphatic ester and 20-120 parts by weight of (methyl) acrylic ester for 2-8h at a temperature of 100-200 DEG C in the presence of polymerization inhibitor relative to 0.5-1.5 percent by mass of the acrylic ester, raising the temperature to 230 DEG C after the reaction is ended, distilling to remove excessive unreacted aliphatic ester under the vacuum degree of 2mmHg, and obtaining diacid diester biological based plasticizer after a product is decolored by active carbon; and carrying out amidation on the distilled unreacted aliphatic ester and ethanediamine for 2-8h at a temperature of 120-200 DEG C to prepare the lubricant ethylene bifatty acid amide. The method realizes the full utilization of the semi-drying oil or drying oil; the prepared plasticizer has no toxicity and environment protection; and the lubricant ethylene bifatty acid amide prepared by using leftovers.

Description

technical field [0001] The invention relates to a utilization method of drying oil or semi-drying oil, in particular to a method for fully utilizing diacid diester and ethylene bisfatty acid amide prepared from drying oil or semi-drying oil. Background technique [0002] Semi-dry oil or dry oil is easy to oxidize and dry in the air to form an elastic and flexible solid film. The main components are glycerides of unsaturated fatty acids such as lycanic acid, linolenic acid, and linoleic acid. The iodine value is above 130. Such as tung oil, linseed oil and eucalyptus oil. my country's dry oil or semi-dry oil was mainly used in traditional Chinese medicine or traditional handicrafts before, and now it is used in more fields after modification of other substances. For example, epoxy linseed oil can be used as a plasticizer. It is a kind of compound containing ternary epoxy group structure, which not only plasticizes polyvinyl chloride, but also can block the continuous decomp...
