preparation example Construction

[0033] The present invention also provides the preparation method of above-mentioned product, and its technology is mainly divided into two steps:

[0034] (1) In the first step, first add the main emulsifier, main dispersant, auxiliary dispersant, antifreeze, and deionized water into the reactor for mixing, and stir for 10 minutes. The temperature in the reactor should be controlled below 0°C.

[0035] (2) In the second step, put the product synthesized in the first step into the oil phase emulsification tank, stir and shear for 30 minutes; then slowly add the co-emulsifier into the tank until the appearance of the material in the tank changes from milky white to half After it becomes transparent, stop the dropwise addition, and continue to cut for 10 minutes before the preparation is completed.

[0036] The present invention optimizes the component types and proportions of the product, and optimizes the design of the overall process, especially adopts the microemulsion prepa...

Embodiment 1

[0039] Formula: OP-10 1%, n-butanol 6%, PVA-4788 5%, CMC 0.2%, methanol 20%, cumyl peroxyneodecanoate 32%, and the balance is deionized water.

[0040] The preparation method is to add OP-10, PVA-4788, CMC 0.2%, methanol, and deionized water to the reactor for mixing, start stirring, control the temperature below 0°C, stir for 10 minutes, then transfer to the oil phase emulsification tank, stir and shear for 30 minutes, Then start to slowly drop n-butanol, stop the dripping after the material appearance in the kettle changes from milky white to translucent rapidly, continue to cut after 10min and complete the preparation to obtain a microemulsion type initiator product with a content of 30%.

Embodiment 2

[0042] Formula: OP-10 1%, n-butanol 8%, PVA-4788 4%, CMC 0.2%, methanol 20%, cumyl peroxyneodecanoate 60%, and the balance is deionized water.

[0043] The preparation method is to add OP-10, PVA-4788, CMC 0.2%, methanol, and deionized water to the reactor for mixing, start stirring, control the temperature below 0°C, stir for 10 minutes, then transfer to the oil phase emulsification tank, stir and shear for 30 minutes, Then start to slowly drop n-butanol, stop the dripping after the material appearance in the kettle changes from milky white to translucent rapidly, continue to cut after 10min and complete the preparation to obtain a microemulsion type initiator product with a content of 50%.

Abstract

The invention discloses an organic peroxide microemulsion type initiator and a preparation method thereof, and belongs to the technical field of initiator preparation. The initiator comprises the following components in percentage by mass: 0.5%-2% of a main emulsifier, 5%-10% of a co-emulsifier, 2%-5% of a main dispersant, 0.1%-0.2% of a co-dispersant, 10%-30% of an antifreeze agent, 30%-60% of an oil phase and the balance of deionized water. The preparation method comprises the following steps: mixing the oil phase with a certain amount of auxiliary materials such as the main emulsifier, the auxiliary emulsifier, the main dispersant, the auxiliary dispersant, the solvent and the like through the process disclosed by the invention, and then homogenizing and emulsifying to obtain a semitransparent uniform and stable microemulsion product. The particle size of the initiator product is lower than 0.08 micrometer, the emulsion stability is high, and when the initiator product is used for PVC polymerization synthesis, the initiation efficiency can be improved, and stable and efficient production of PVC is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of initiator preparation, and more specifically relates to an organic peroxygen microemulsion initiator and a preparation method thereof. Background technique [0002] PVC is one of the most widely used general-purpose plastics in the world. There are a wide range of applications. More than 75% of PVC is produced by suspension polymerization, and the initiators used in production are usually mixed with two or three emulsion initiators. [0003] At present, the initiators used in the production of PVC are usually organic peroxides, and the organic peroxy liquid initiators are mainly divided into two types: solvent type and emulsion type, which are used according to different polymerization types. Solvent type is generally used in Bulk polymerization, no dispersion requirements, high polymerization efficiency, and emulsion initiators are often used in suspension polymerization, the particle size of the dispe...
