Embodiment 1

[0029] Embodiment 1 bamboo fiber pretreatment

[0030] Take 4g bamboo fiber and place it in 100g mass fraction of 15% sodium hydroxide solution, ultrasonically treat it for 30min, wash to neutral and dry to constant weight in a 50°C oven, when the concentration of sodium periodate is 20g / L, The reaction temperature was 40° C., and the reaction was carried out at pH 3 for 4 hours, and the content of aldehyde group was determined to be 1.67 mmol / g.

Embodiment 2

[0031] Embodiment 2 bamboo fiber pretreatment.

[0032] This example is basically the same as Example 1, except that the mass fraction of sodium hydroxide solution is 20%, the ultrasonic time is 40min, the oxidation reaction conditions are the same, and the measured aldehyde content is 1.90mmol / g.

Embodiment 3

[0033] Embodiment 3 bamboo fiber pretreatment.

[0034] This example is basically the same as Example 1, except that the mass fraction of sodium hydroxide solution is 25%, the oxidation reaction conditions are the same, and the measured aldehyde content is 2.10 mmol / g.

Abstract

The invention discloses a preparation method and application of modified natural bamboo fiber materials. The preparation method comprises the steps as follows: enabling natural bamboo fibers to perform an oxidizing reaction by adopting a strong oxidant, and obtaining dialdehyde natural bamboo fibers; using the dialdehyde natural bamboo fibers for reacting with ethylenediamine, and obtaining the grafted natural bamboo fibers, that is, the modified natural bamboo fiber materials. The obtained grafted natural bamboo fibers are used for adsorbing formaldehyde to investigate the adsorption effect. The method disclosed by the invention modifies the natural bamboo fibers with an oxidation method and an amination method, the process is simple, raw materials are cheap, and the modified natural bamboo fibers have a relatively good adsorption effect on formaldehyde.

Description

technical field [0001] The invention belongs to the field of environmental protection materials, and in particular relates to a preparation method and application of a modified bamboo fiber material. Background technique [0002] As one of the origins and distribution centers of bamboo plants, my country has the most abundant bamboo resources and is known as the "Kingdom of Bamboo". As a renewable resource and biomass raw material, bamboo is expected to contribute to the improvement of resource shortages, environmental pollution and other issues. The non-toxic, harmless and non-polluting natural cellulose fibers prepared by physical methods are called bamboo fibres, which basically retain the natural superior properties of bamboo fibers, have excellent moisture absorption and release properties, and can be antibacterial and anti-ultraviolet. [0003] As an environmentally friendly biomass cellulose fiber, the oxidation of bamboo fiber is of great significance; the oxidized ...
