Abstract

The invention belongs to the technical field of environment-friendly product preparation, and provides an environment-friendly foam preparation. The environment-friendly foam preparation is prepared from the following raw materials in percentage by weight: 5-15% of lauryl sodium sulfate, 2-6% of octaphenyl polyoxyethyiene, 2-6% of alkylphenol ethoxylate, 4-10% of a foam stabilizer, 0.2-2% of a preservative, 0.2-1% of a stabilizer, 0.2-2% of a foam aid and the balance of water. All the raw materials are green and environmentally friendly and have biodegradability. The environment-friendly foampreparation has high temperature resistance, the highest temperature can reach 150 DEG C, the high salinity resistance is achieved, the highest salinity can reach 300 g / L, the high oil resistance is achieved, and the highest condensate oil content can reach 30%. Good foaming capability, foam stabilizing capability and liquid carrying capability are achieved. The environment-friendly shield foamingagent disclosed by the invention is stable in quality and good in corrosion resistance, is not influenced by the storage temperature and storage time, and has a relatively long shelf life. The preparation method is simple to operate, easy to prepare and suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of preparation of environment-friendly products, relates to an environment-friendly foam preparation, and also relates to a preparation method of the environment-friendly foam preparation. Background technique [0002] With the rapid development of society and economy and the continuous acceleration of urbanization, the development and utilization of urban underground space has become one of the important directions for the sustainable development of our society. The construction of underground transportation facilities has entered a stage of rapid development. In the shield construction technology of underground engineering that has attracted much attention, the earth pressure balance shield has been widely used due to its advantages of wide application range and low cost, and has become the mainstream of tunnel technology. When excavating in the mode of earth pressure balance, such as in the sand layer, gr...
