Formaldehyde purification material and preparation method thereof

Abstract

The invention discloses a formaldehyde purification material and a preparation method thereof. The formaldehyde purification material comprises a sponge outer sleeve and a fiber inner core, and the fiber inner core is arranged on the inner side of the sponge outer sleeve. The preparation method comprises the following steps: uniformly sprinkling activated carbon powder on a sponge outer sleeve, soaking the sponge outer sleeve into a nano titanium dioxide dispersion liquid, soaking silk fibers into a formaldehyde purification liquid, and putting the silk fibers into the inner side of the spongeouter sleeve to obtain a formaldehyde purification material. The formaldehyde purification liquid is absorbed through the silk fibers, diatomite in the formaldehyde purification liquid can absorb formaldehyde, the diatomite can exist in the silk fibers for a long time, the formaldehyde purification effect is lasting, the activated carbon powder is evenly distributed in the sponge outer sleeve, the formaldehyde purification effect is guaranteed, meanwhile, the production efficiency is improved, nano titanium dioxide is loaded on activated carbon in the sponge outer sleeve, and the formaldehydepurification effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a formaldehyde purification material and a preparation method thereof. Background technique [0002] Formaldehyde is highly toxic. Long-term exposure or inhalation of low-concentration formaldehyde gas can cause an increase in chronic respiratory diseases. Symptoms of poisoning include headache, neurasthenia, anxiety, dizziness, and decreased nervous system function. The liver, skin, and immune system all have certain toxic effects. What's more serious is that formaldehyde is carcinogenic. Therefore, the purification of formaldehyde is the key to indoor pollution purification; the purification effect of traditional formaldehyde purification materials is not long-lasting, and it is easy to lose the purification effect after a long time. As a result, the production efficiency of existing formaldehyde purification materials is low, and traditional formaldehyde purificatio...

Problems solved by technology

[0004] The invention drives two mounting plates to move towards each other through a double-headed cylinder, and drives two clamping frames to move closer to each other. Clamping and fixing, the activated carbon powder is sprinkled downward on one side of the sponge coat through the discharge port, and the connecting seat is driven to rotate by rotating the motor, and the sponge coat is rotated by 180 degrees, so that the sponge coat is turned over and the activated carbon powder is sprinkled evenly On the other side of the sponge cover, the vibration motor drives the sponge cover to vibrate, so that the activated carbon powder enters the sponge cover. The invention can quickly enter the non-toxic carbon powder into the sponge cover, which solves the uneven distribution of activated carbon in traditional formaldehyde purification materials. , the formaldehyde purification effect cannot be guaranteed, and the technical problem of low production efficiency of the formaldehyde purification material;
