[0002] With the improvement of people's living standards, indoor decoration is more and more common, but indoor formaldehyde pollution problem is increasingly serious, and it constitutes a threat to people's health. Formaldehyde is a colorless gas with strong irritating odor, which is determined as a class of carcinogens by the International Agency for Research on Cancer (IARC), and long-term exposure to formaldehyde may cause respiratory diseases, abnormal immune function, and even serious diseases such as nasopharyngeal carcinoma and leukemia, especially the physical harm to vulnerable groups such as pregnant women, infants, children and the elderly is more serious. Indoor formaldehyde pollution is mainly from decoration materials, furniture and various textiles, such as artificial board, paint, coating, adhesive, carpet, curtain, sofa, etc., and the formaldehyde release time can last for more than ten years, which threatens the indoor air quality for a long time.

[0003] As a common indoor decoration, carpet not only beautifies the environment, reduces noise and provides comfortable foot feeling, but also has certain adsorption function. The U.S. Environmental Protection Agency (EPA) found that carpets can temporarily adsorb dust, formaldehyde, sulfur dioxide and other particles like filters. However, the traditional carpet has limited ability to adsorb formaldehyde, which cannot meet people's high requirements for indoor air quality.

[0004] Based on this, an environmental protection carpet that can adsorb formaldehyde is provided, which can eliminate the drawbacks of existing devices. CONTENT OF THE UTILITY MODEL

[0008] On the basis of the above technical scheme, the utility model also provides the following optional technical scheme:

[0010] In an alternative, the upper interlayer and the lower interlayer are both non-woven interlayers made of hydrophilic polymer materials, and the net aldehyde agent bearing layer has a thickness of 0.2-0.3mm.

[0011] In an alternative, the net aldehyde agent layer uses net aldehyde antibacterial agent KEPUYIN-Q02, and the net aldehyde agent layer has a spraying concentration of 50g / m2.

[0012] In an alternative, the covering layer uses a transparent polytetrafluoroethylene film, and the covering layer has a thickness of 0.5-0.8mm.

[0013] In an alternative, the covering layer is added with an antistatic additive.

[0014] In an alternative, the catalytic acceleration layer is composed of a photocatalytic material and a catalyst carrier.

[0015] In an alternative, the lower end of the covering layer is provided with an anti-skid coating layer composed of natural rubber and silicone rubber.

[0016] Compared with the prior art, the present application has the following advantages:
