Abstract

The invention belongs to the technical field of environmental protection, in particular to a novel activated carbon filter for an air purifier. The novel activated carbon filter is prepared from the following components in percentage by weight: 35-50% of activated carbon, 30-40% of a high polymer thermo-melting material, 2-5% of a nano carbon material, 2-8% of crystal series nano-silver, 2-5% of an oxidizing agent, 2-5% of a getter and an appropriate amount of polyurethane foam. The preparation method comprises the following steps: (1) soaking and airing the polyurethane foam; (2) mixing the activated carbon, the high polymer thermo-melting material, the nano carbon material, the crystal series nano-silver, the oxidizing agent and the getter to prepare active powder; (3) mixing, heating and fusing the active powder and the polyurethane foam prepared in the step (1), and adding the mixture into a mold to make cellular activated carbon; (4) drying; and (5) making an outer frame. According to the novel activated carbon filter disclosed by the invention, the nano carbon material is added during the making process of the activated carbon filter, and the making process technology of theactivated carbon filter is innovated, so that the activity and adsorptivity of the activated carbon filter are greatly improved, and the air purification efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to a novel activated carbon filter screen for an air purifier. Background technique [0002] With the development of modern industrialization, environmental pollution is becoming more and more serious, indoor and outdoor air quality is seriously declining, and human health is gradually being violated by air pollution. Air pollution is an urgent problem to be solved in the industry. At present, people mainly use air purifiers to purify indoor air. There are nearly a thousand kinds of air purifier products on the market. Although the focus of each brand's publicity is different, there are mainly four core purification technologies: physical filtration, electrostatic dust collection, Negative ion plasma purification, photocatalyst technology; most of these four purification technologies are purified in the form of filters, and the quality of the filters directly determ...
