Abstract

The invention discloses a filtering membrane for treating volatile organic compounds. The filtering membrane comprises the following raw materials by weight part: 40-80 parts of feldspar, 30-50 parts of quartz, 10-20 parts of sodium silicate, 16-24 parts of activated carbon, 10-15 parts of zeolite, 8-12 parts of kieselguhr, 6-10 parts of carbon fiber, 2-3 parts of glass fiber, 0.4-0.6 part of catalyst, 0.5-0.8 part of cross-linking agent, 0.3-0.5 part of tackifier, 0.8-1.5 parts of plasticizer, 0.9-1.6 parts of flexibilizer and 0.4-0.6 part of stabilizer. The filtering membrane for treating volatile organic compounds provided by the invention is rich in active carbon, kieselguhr and zeolite, can directly absorb toxic gas including VOCs and has the characteristics of permanent use, high temperature and high pressure resistance, corrosion resistance, high absorption efficiency, excellent anti-seismic property and low preparation cost.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of membrane material preparation, and in particular relates to a filter membrane used for treating volatile organic compounds. [0003] 【Background technique】 [0004] The main components of VOCs are: hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons and nitrogen hydrocarbons, which include: benzene series, organic chlorides, Freon series, organic ketones, amines, alcohols, ethers, esters, acids and petroleum hydrocarbon compounds Wait. VOCs is the English abbreviation of Volatile Organic Compounds, and the chemical substances (except heavy metals) in wall paints that are commonly referred to as harmful to the human body refer to VOCs. These volatile organic compounds include formaldehyde, ammonia, ethylene glycol, esters and other substances. When VOCs in the room reach a certain concentration, it will cause symptoms such as headache, nausea, vomiting, fatigue, etc., and even cause convu...
