Description
Technical Field
The present invention relates to the field of pollution control in a room or a vehicle, and in particular, to a polyvinyl chloride (PVC) composition for removing formaldehyde and a foot mat manufactured therefrom.
Background
Harmful gases such as formaldehyde are one of the main pollution sources in newly-installed and repaired houses. Various products for eliminating harmful gases such as formaldehyde have been developed to absorb or adsorb indoor harmful gas pollution.
In addition, the automobile foot pad is a common article in an automobile, can absorb water, absorb dust and remove dirt, effectively prevents residual moisture, dirt and the like on the sole from causing sliding with the clutch, the brake and the accelerator, avoids potential safety hazards and reduces the possibility of polluting and damaging the interior trim. But in many new cars, can remain a lot of organic gas, for example formaldehyde and all kinds of VOC gas, car callus on the sole if can provide formaldehyde removal effect, will solve the puzzlement of many people. Especially, the foot pad of the automobile has large using area in the automobile and is beneficial to removing formaldehyde.
However, very few footbeds with similar functions are currently available on the market. At present, products for removing formaldehyde statically in a vehicle are divided into two types, one type is a spray type spray, and the other type is an activated carbon bag. Some of the spray products contain titanium dioxide nanoparticles, which can react quickly with formaldehyde, but because formaldehyde is constantly volatilized, the spray sprays fail quickly. The activated carbon bag type products are mostly made of common coconut shell activated carbon, formaldehyde is absorbed only by adsorption, and after the adsorption is saturated, the activated carbon bag type products are easy to desorb, so that the concentration of the formaldehyde is increased again.
Therefore, there is a need to develop a product for pollution control in a room or a vehicle, which has no organic gas odor and can statically adsorb formaldehyde for a long period of time.
