Abstract

Belonging to the technical field of foaming agent design and preparation, the invention relates to a foaming agent containing lauryl dimethyl amine oxide and calcium carbonate. The foaming agent containing lauryl dimethyl amine oxide and calcium carbonate includes the following components by mass fraction: 15-55 parts of calcium carbonate, 10-25 parts of lauryl dimethyl amine oxide, 10-20 parts ofN-butyldiethanolamine, 0.01-5 parts of a silicon resin polyether emulsion, and 5-10 parts of water. The foaming agent provided by the invention has the characteristics of reasonable component designand simple preparation process, and the obtained product has relatively uniform foaming speed and excellent application effect.

Description

technical field [0001] The invention relates to a foaming agent containing dodecyl dimethyl amine oxide and calcium carbonate, belonging to the technical field of foaming agent design and preparation. Background technique [0002] The so-called foaming agent is the substance that makes the target substance form holes, 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 su...
