Abstract

The invention discloses a solvent-type tert-butyl peroxyneodecanoate initiator and application thereof, and relates to the technical field of organic peroxide initiators. It is prepared by the following method: (1) Dissolving the homogeneous agent in antifreeze to obtain solution 1; (2) adding isododecane to tert-butyl peroxyneodecanoate to obtain solution 2; (3) Add solution 1 to solution 2 to obtain the solvent-based tert-butyl peroxyneodecanoate initiator. The present invention introduces the mixed solution of homogeneous agent and antifreeze, so that the product is still uniform and stable when used at -20°C, without precipitation of ice flakes and ice chips, and can save the steps of deep refrigeration and ice filtering of the original solution in the production of solvent-based products. Effectively reduce labor intensity and production cycle, reduce PVC production cost, and improve resin quality.

Description

technical field [0001] The invention relates to the technical field of organic peroxide initiators, in particular to a solvent-based tert-butyl peroxyneodecanoate initiator and an application thereof. Background technique [0002] PVC resin is a general-purpose resin with large output and excellent comprehensive performance. Its products have excellent mechanical properties, flame retardancy, transparency, chemical resistance, etc., and are widely used in industry, construction, agriculture, daily life, packaging It plays a very important role in balancing the chlorine gas by-product of caustic soda, an important chemical raw material. [0003] In recent years, with the continuous increase of domestic PVC resin production capacity, the variety and demand of PVC synthesis initiators have increased rapidly. There are many production methods of PVC, such as bulk polymerization, emulsion polymerization, suspension polymerization and microsuspension polymerization, etc. The susp...
