Environment-friendly absorbent for absorbing formaldehyde and preparation method thereof

Abstract

The invention discloses an environment-friendly absorbent for absorbing formaldehyde and a preparation method thereof. The environment-friendly absorbent comprises the following raw materials in partsby weight: 28-40 parts of bamboo charcoal fiber, 33-36 parts of diatom powder, 15-20 parts of sepiolite fiber, 150-170 parts of vinyl acetate, 42-49 parts of polyethylene, 2-4 parts of polyimide, 1-3parts of azodiisobutyronitrile, 2-3 parts of 1,3-dimethyl-2-imidazolinone, 10-12 parts of a silicone resin polyether emulsion, 15-17 parts of an aqueous tert-butyl alcohol solution, 3-5 parts of sodium alpha-olefin sulfonate, 11-14 parts of fluoroalkyl polyether modified polysiloxane, 2-4 parts of nonylphenol polyoxyethylene ether, 10-12 parts of alums, 18-21 parts of sodium bicarbonate and 3-6 parts of Arabic gum. The environment-friendly absorbent for absorbing formaldehyde has good formaldehyde absorption capacity and excellent buffering and shock-resisting effects.

Description

technical field [0001] The invention relates to an environment-friendly absorbent for absorbing formaldehyde. Background technique [0002] In daily life, people spend 80% of their time indoors. Long-term exposure to low-concentration formaldehyde can cause chronic respiratory diseases, while exposure to high-concentration formaldehyde can cause nuclear gene mutations in severe cases. my country's "Indoor Air Quality Standards" stipulates that the maximum concentration of formaldehyde in indoor rooms is 0.1mg / m3, and the concentration of formaldehyde in most newly renovated houses exceeds the standard by 5 to 10 times within 5 to 10 months. The method of ventilation and drying achieves the purpose of reducing indoor formaldehyde, but this method has a long cycle and is greatly affected by the ambient temperature, which not only causes incomplete removal, but also brings a lot of inconvenience to the residents. Therefore, various formaldehyde absorbents should be shipped Howev...

my country's "Indoor Air Quality Standards" stipulates that the maximum concentration of formaldehyde in indoor rooms is 0.1mg / m3, and the concentration of formaldehyde in most newly renovated houses exceeds the standard by 5 to 10 times within 5 to 10 months. The method of ventilation and drying achieves the purpose of reducing indoor formaldehyde, but this method has a long cycle and is greatly affected by the ambient temperature, which not only causes incomplete removal, but also brings a lot of inconvenience to the residents. Therefore, various formaldehyde absorbents should be shipped However, the current formaldehyde absorbent is only used to absorb formaldehyde, and has a single purpose, so it is necessary to improve
