Abstract

The invention relates to a solid environment-friendly foaming agent and a preparation method thereof. The foaming agent is prepared from the following components in percentage by weight: 75 to 85 percent of foaming main material, 1.4 to 1.8 percent of active auxiliary agent, 0.1 to 0.2 percent of coupling agent, 0.1 to 0.2 percent of catalyst, and the balance of talc, wherein the foaming main material is sodium bicarbonate. The preparation method comprises the following steps: S1, preparing raw materials; S2, mixing and stirring; S3, crushing and coating: after crushing the raw materials mixedin step S2 twice, adding the catalyst to stir for 2 to 3 minutes, and then adding the coupling agent and stirring for 8 to 10 minutes to obtain the finished product. The solid environment-friendly foaming agent has the advantages of environmental protection, low cost, stable gas generation and high decomposition rate.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a solid environment-friendly foaming agent and a preparation method thereof. Background technique [0002] Foaming agent is the substance that makes the target substance form pores, and it can be divided into three categories: chemical foaming agent, physical foaming agent and surfactant. Chemical blowing agents are those compounds that release gases such as carbon dioxide and nitrogen after thermal decomposition, and form pores in the polymer composition; physical blowing agents are foam pores that change the physical form of a certain substance , which is formed by the expansion of compressed gas, the volatilization of liquid or the dissolution of solid; the foaming agent has high surface activity, which can effectively reduce the surface tension of the liquid, and arrange the double electron layer on the surface of the liquid film to surround the air , forming bubbles,...
