Problems solved by technology

High-concentration formaldehyde has toxic effects on the nervous system, immune system, liver, etc. For environmental protection, people choose decorative panels with less glue content as much as possible, and replace traditional paint or composite decorative panels with wood-plastic panels. The environmental protection performance of advanced wood-plastic panels is reflected in the fact that it does not release formaldehyde itself, but there are other sources of formaldehyde release during the decoration process, such as furniture or glass glue, etc. The existing wood-plastic panels do not have the function of absorbing or decomposing formaldehyde. There are limitations in the application in the decoration market

Description

technical field [0001] The invention relates to the field of carbon-plastic composite materials, and more specifically relates to a manufacturing process of a highly adsorbable carbon-plastic composite material. Background technique [0002] At present, most of the furniture, paints, coatings, or other decorative materials used in interior decoration volatilize and release gaseous formaldehyde into the air to varying degrees, and some even release gaseous formaldehyde in high concentrations and for a long time, making indoor formaldehyde The concentration seriously exceeds the limit of the relevant standards, especially when the indoor formaldehyde concentration is at the peak at the beginning of the decoration. Formaldehyde is a colorless gas with a strong pungent smell. It is very volatile at room temperature, and the volatile amount increases with the temperature. And increase, it has a strong stimulating effect on human skin and mucous membranes, and can be converted int...
