Mercapto-group stabilizing agent and preparation method

Abstract

The invention discloses a mercapto-group stabilizing agent and a preparation method. The mercapto-group stabilizing agent comprises, by weight, 80 to 120 parts of ethylene glycol monobutyl ether, 130 to 160 parts of odorless kerosene, 280 to 330 parts of mercaptoacetic acid-2-ethylhexanoate, 3 to 6 parts of glacial acetic acid and 280 to 330 parts of di-n-octyltin oxide. The preparation method comprises the following steps: feeding of the components; heating to a temperature of 100 to 105 DEG C and esterification; maintenance of a reflux state for 1.5 h; and dehydration under a vacuum pressure of -0.06 mpa at a high temperature of 130 DEG C. The stabilizing agent has the advantages of no toxicity, no color, no odor, good thermal stability, resistance to aging, environment friendliness, improvement of light transmittance, toughness and the yield rate of a product, no discharge in a production process, convenient usage and wide market prospects.

Description

technical field

[0001] The invention discloses a chemical stabilizer and a preparation method, in particular to a stabilizer containing mercapto groups. Background technique

[0002] In recent years, the plastic industry has developed rapidly, and plastic products are becoming more and more non-toxic, tasteless, tough and durable. In particular, the pace of innovation of plastic composite materials is accelerating, especially the non-toxic, colorless and environmentally friendly chemical additives required by special industries such as aerospace, electronics, facility agriculture, construction, and food packaging. Good plastic additives are relatively lagging behind, and domestic production Very little, and the quality is unstable, affecting the light transmittance and tolerance of the product, anti-aging, and poor oxidation ability. Although a large number of European and American products have poured into my country, their prices are high, their performance is unstable, a...
