Abstract

The invention discloses an air purification composite material, which includes a VOC catalytic digestion layer, wherein the VOC catalytic digestion layer includes an active component, an activator and a catalyst carrier. The invention provides a low-resistance and high-efficiency air-purifying composite material, which can achieve extremely high interception efficiency by superimposing multi-layer filter materials; adopts multi-stage filtration to classify solid pollutants, and has a better filtering effect , The service life and effect of the material are longer.

Description

technical field [0001] The invention relates to the field of air purification, more specifically, it relates to an air purification composite material. Background technique [0002] In view of the current increasingly serious air pollution situation, it is necessary to research and develop air purification products suitable for China's national conditions. Although the industry has launched various air purification products such as air filter purifiers and indoor fresh air systems, at present, there are still various problems in the most core filter materials in the air purification industry. [0003] The core indicators of filter materials for air purification are filtration efficiency, air resistance, service life, decay rate, etc. At present, the common filter materials on the market are mainly glass fiber materials, high-efficiency melt-blown non-woven fabrics and multi-effect filter materials with deodorizing and antibacterial functional layers. [0004] Glass fiber m...
