Abstract

The invention discloses a formula of a formaldehyde remover made from a natural plant extract and a preparation method thereof. The raw material of the formaldehyde remover is the natural plant extract which can react with formaldehyde with high efficiency. After being prepared, the solution of the formaldehyde remover is added into adhesives, or sprayed on the surfaces of furniture or plates or sprayed into the air to make formaldehyde content of a post-processed products or space meet the requirements of national standards.

Description

technical field [0001] The invention relates to a preparation for eliminating harmful chemical substances and a preparation method thereof, in particular to a preparation for removing formaldehyde and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, room decoration and the purchase of new furniture have become commonplace in people's lives. Various wood-based panels are widely used in room decoration and furniture manufacturing, such as plywood, blockboard, medium and high-density fiberboard, and particle board. More than 90% of the adhesives used in these wood-based panels are resin products made of formaldehyde, which inevitably has the problem of formaldehyde release during use, which has become the main source of formaldehyde pollution in indoor air. According to statistics, the formaldehyde emission of wood-based panels is as long as 3-15 years. At present, the formaldehyde pollution in newly renovated home...
