Description
Technical field
The present invention relates to technical field of active carbon more particularly to a kind of preparation methods of indoor formaldehyde adsorbent.
Background technique
With the rise of interior decoration, the formaldehyde that finishing material is discharged have become in room air major pollutants it
One.The artificial wooden boards such as finishing used glued board, medium density fiberboard, three-ply board, compoiste wood floor be by urea-formaldehyde resin adhesive or
Phenolic resin gluing knot forms, and free formaldehyde is contained in these resin glues, can be released slowly into air at normal temperatures and pressures
In.And formaldehyde harm to the human body is big, research finds that the generation of many diseases and formaldehyde are closely bound up to the murder by poisoning of people.With people
The reinforcement of environmental consciousness and the raising to environmental quality requirement, how effectively to prevent and administer formaldehyde increasingly by people's
Pay attention to.Formaldehyde adsorbent product currently on the market haves the defects that be more toxic, formaldehyde removal efficiency is low and action time is short,
It limits its application.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of preparation method of indoor formaldehyde adsorbent,
Product has the advantages that non-toxic, formaldehyde removal efficiency is high and long action time is waited so long.
A kind of preparation method of indoor formaldehyde adsorbent proposed by the present invention, includes the following steps：

Preferably, in S2, in ultrasonication, ultrasonic power 350-420W, ultrasonic time 60-75min.
Preferably, in S3, by material B in 250-280 DEG C of roasting 1.5-2h.
Preferably, in S3, the weight ratio between material B and tea grounds is 10-15:2-4.
Preparation process of the present invention is simple, and using bamboo charcoal powder, diatomite and tea grounds as major ingredient, raw material sources are wide, at low cost, passes through
It is modified that functionally there is synergistic effect with tea grounds to bamboo charcoal powder, diatomite modified, the product nontoxicity that makes, formaldehyde
Advantage that removal efficiency is high and long action time is waited so long.Wherein, by the way that bamboo charcoal powder and diatomite to be placed in the mixing of oxalic acid and hydrochloric acid
It impregnates, filters in aqueous solution, cleaning, sour modified effect is significantly more than oxalic acid and hydrochloric acid single acid modified effect, effectively removing bamboo
Impurity in powdered carbon and diatomite, and make it with oxygen-containing group, then carry out in the mixed aqueous solution of iron chloride and potassium permanganate
Ultrasonic treatment, ferro element and manganese element are effectively adsorbed in active carbon and zeolite, in 250-280 DEG C of roasting 1.5-2h, avoid height
Temperature roasting bring charcoal loss, while further remove inner surface impurity, increase inside and outside surface-active, improve its load capacity and
Load effect improves the absorption Scavenging activity of its PARA FORMALDEHYDE PRILLS(91,95), then cooperates with tea grounds, takes full advantage of tea grounds resource, each material phase
Capacitive is good, and system polar groups content increases, and can further improve the absorption Scavenging activity of inventive article PARA FORMALDEHYDE PRILLS(91,95).
Test discovery：It is that 0.5g inventive article is put into 30mg/L formalin in 50ml concentration, formaldehyde absorbing removal
Rate is more than 95.2%.
