Granule foaming agent

Abstract

The invention relates to the field of chemical industry, and discloses a preparation method of a granule foaming agent. The method comprises the following steps: evenly mixing rubber or plastic with a foaming agent; kneading the mixed material by using a kneading machine; and granulating the mixed material by using a granulator in a heating and pressing manner, thereby obtaining the granule foaming agent. The granule foaming agent can also be formed by evenly mixing a dispersing agent, a surfactant, rubber or plastic and the foaming agent. The prepared granule foaming agent has the advantages of being difficult to spatter, difficult in causing of pollution and person injury, easy to transport, good in product foaming effect and the like.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a preparation method of a granular foaming agent. Background technique [0002] Currently known blowing agents are all powdery or liquid. There are many inconveniences in the use process. The powder foaming agent is easy to scatter in the air when mixing, causing environmental pollution and harm to the human body. Most of them are flammable and explosive, and they are easy to be exposed and scatter during storage and transportation. It is easy to burn and explode when it comes into contact with a fire source; the liquid foaming agent needs a large number of special containers during storage and transportation, and it is easy to leak and cause danger, and it is easy to volatilize in the air when mixing, causing environmental pollution and damage to the environment Injury to the human body, it is easy to react with acid, alkali or water to cause explosion and combustion; powder an...
