Abstract

The invention discloses a preparation method of a composite material for absorbing and decomposing formaldehyde and VOVs, which comprises the following steps: (1) preparation of the main ingredient: PVC, zinc stearate, chlorinated polyethylene, stearic acid, epoxy soybean oil meal , azodicarbonamide, nano-zinc oxide, nano-titanium dioxide, and semicarbazide are stirred at high speed to prepare the main agent. (2) Blend preparation: the main ingredient, calcium carbonate powder, titanium dioxide, and sodium bicarbonate were stirred at high speed to prepare a blend. (3) Foam board preparation: the blend is heated and foamed in an extruder, and extruded into a composite material. The composite material has good formaldehyde purification efficiency and formaldehyde purification persistence, can be used alone, and can also be used to prepare adhesive modification, wood-based panel veneer, and decorative panels.

Description

technical field [0001] The invention relates to the technical field of wood-based panel processing, in particular to a method for preparing a composite material for absorbing and decomposing formaldehyde and VOVs. Background technique [0002] With the improvement of people's quality of life, the decoration requirements for furniture are getting higher and higher, but most of the adhesives and paints used in the furniture production process have the problem of releasing organic pollutants such as formaldehyde, especially in summer, the amount of formaldehyde released is obvious speed up, it will be harmful to human health. Coating a coating with formaldehyde adsorption function on the surface of the board can reduce the indoor formaldehyde concentration to a certain extent, but the thickness of the coating is limited, and it is easy to wear during use, so the long-term removal effect on formaldehyde is limited. [0003] PVC foam board, also known as Chevron board or Andy bo...
