Abstract

The invention belongs to the technical field of petroleum processing, in particular to a stabilizer. The stabilizer comprises the following materials in parts by weight: 4-6 parts of organic tin, 4-6parts of lead salt, 3-5 parts of organic antimony, 3-5 parts of metal soap, 6-8 parts of a rare earth stabilizer, 6-8 parts of cadmium laurate, 3-5 parts of zinc laurate, 6-8 parts of bisphenol A, 4-6parts of 2,6-di-tert-butyl-p-cresol and 100-300 parts of distilled water. After adoption of a ratio, the stabilizer can be avoided from deactivation under direct sunlight by being put into a brown glass bottle, so that the shelf life of the stabilizer is prolonged; the rear earth stabilizer is added into the stabilizer, and the composite rear earth stabilizer is synthesized from carboxylate or fatty acid salt of a rare earth element as a main component and contains a proper amount of rare earth metal component; the stabilizer not only can replace lead cadmium salt-type and organic tin-type toxic stabilizers and the like, but also has very good heat stability, light stability, transparency and coloring power.

Description

technical field [0001] The invention belongs to the technical field of processing oilfield chemical additives, and in particular relates to a stabilizer and a preparation method thereof. Background technique [0002] Stabilizers, broadly speaking, chemicals that can increase the stability of solutions, colloids, solids, and mixtures are called stabilizers, which can slow down reactions, maintain chemical balance, reduce surface tension, and prevent light, thermal decomposition, or oxidative decomposition. , the sources of chemical stabilizers in a broad sense are very extensive, mainly according to the design purpose of the formulator, any chemical can be used flexibly to achieve the purpose of product quality stability. [0003] In oil processing operations, generally work in a leaky environment. Stabilizers are indispensable materials in oil processing operations. The original stabilizers are easy to deteriorate when placed, and when exposed to direct sunlight, the activit...
