Abstract

The invention discloses an adsorption material for gas masks. The adsorption material comprises the following components by mass: 15-25 parts of montmorillonite, 10-20 parts of modified activated carbon, and 5-8 parts of a biomass adsorbent. The biomass adsorbent is prepared by: drying and crushing corncob or bagasse, dispersing the obtained crushed material into a mixed solution of deionized water and ethanol to form a suspension solution, then adding citric acid, carrying out staged constant temperature standing, then adding baking soda, and performing washing and drying. The adsorption material for gas masks obtained by the invention has good adsorption function, can effectively absorb various suspended matters in the air, also has weak electrical conductivity, and can play an antistatic role. The adsorption material for gas masks obtained by the invention also can effectively inhibit microorganism growth and avoid mildewing. The obtained adsorption material for gas masks is low in cost and convenient for use, and is also applicable to interior decoration, air purification and other fields.

Description

technical field [0001] The invention belongs to the technical field of protective equipment and relates to an adsorption material for a gas mask. Background technique [0002] A gas mask is a kind of anti-virus product that protects the respiratory system of personnel. It is generally composed of a filter box or a canister and a mask body. The main body of the mask isolates the air and acts as a seal; the canister of the poison box plays the role of filtering poisonous gas and dust, and is mainly used in the working environment with low concentration of harmful gas and dust. Respirators are widely used in the fields of petroleum, chemical industry, mining, metallurgy, military, fire protection, emergency rescue and disaster relief, health and epidemic prevention, technology and environmental protection. [0003] Existing gas respirator is to place activated carbon or disinfectant medicine at the air intake of mouth mask, and the poisonous air on the job site is sucked into ...
