Pasty organic peroxide cross-linking agent and compounding process thereof

Abstract

The invention discloses a pasty organic peroxide cross-linking agent, belongs to the technical field of peroxide cross-linking agents, and particularly relates to a pasty organic peroxide cross-linking agent and a compounding process thereof. The pasty organic peroxide cross-linking agent is characterized by comprising the following components by weight: 47%-53% of dibenzoyl peroxide, 14%-18% of water, 0.1%-2.0% of a non-ionic surfactant, 20%-26% of a desensitizer and 4%-15% of inorganic filler. The pasty organic peroxide cross-linking agent provided by the invention has the positive effects of uniform product, no layering, convenient transportation and use, safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of peroxide crosslinking agents, in particular to a pasty organic peroxide crosslinking agent and its compounding process. Background technique [0002] High-purity organic peroxides are extremely sensitive to heat, shock, impact and friction, and are easily decomposed, producing a large amount of methane, ethane, acetone, carbon dioxide and other gases. The pressure of destroying the package can easily lead to explosion and fire. In order to ensure the safety of organic peroxides in use and storage, auxiliary materials such as phlegmatizers and stabilizers are usually added to high-purity organic peroxides to form a mixture with stable properties and uniform texture. Water is the most common and cheap phlegmatizer, but after high-purity organic peroxides are dispersed in water, system instability such as settling and floating often occurs, resulting in poor product uniformity and affecting product use.

Water is the most common and cheap desensitizer, but after high-purity organic peroxides are dispersed in water, system instability such as settling and floating often occurs, resulting in poor product uniformity and affecting product use

At the same time, simply dispersing high-purity organic peroxides into water, since the subsequent reaction system is usually in an organic environment, it is easy to cause the problem of uneven dispersion during use

Moreover, when the ambient temperature is lower than 0°C, the water is easy to freeze, resulting in an increase in the relative concentration of high-purity organic peroxides and increased risk.
