Description

High-yellowing-resistant herbal clear-flavored furniture and preparation method thereof

technical field

The invention relates to the technical field of furniture processing, in particular to a high-yellowing-resistant herbal-flavored furniture and a preparation method thereof.

Background technique

In China in the 21st century, with the further opening of the market, more and more novel styles of furniture have appeared. After the basic living needs are met, some people begin to pay attention to the quality of home life, especially the impact of home products on health. Therefore, environmental protection furniture is gradually being valued by people, and the trend of green consumption has also promoted the development of environmental protection furniture.

Environmentally friendly furniture refers to those furniture based on the ecological industry, rationally developed and produced using natural materials that can meet the specific needs of users, benefit the health of users, and have extremely high cultural heritage and technological content. It contains several meanings: first, the furniture itself is non-polluting and non-toxic; second, it must have high artistic connotation and aesthetic function, echo the interior design, and create a harmonious and beautiful home office environment; third, it is easy to recycle, process, Reuse, when the furniture is no longer used for disposal, there is no pollution to the environment.

Panel furniture refers to the disassembled and assembled furniture with wood-based panels as the main base material and panels as the basic structure. Common wood-based panels include plywood, blockboard, particleboard, and medium-density fiberboard. Plywood (plywood) is often used to make furniture that needs to be bent and deformed; the performance of blockboard is sometimes affected by the core material; particleboard (also known as particle board, bagasse board) is loose and only used for low-end furniture. The most cost-effective and most commonly used is medium density fiberboard (MDF). Common finishing materials for panel furniture include veneer (commonly known as veneer), wood grain paper (commonly known as sticker), PVC rubber board, polyester paint surface (commonly known as baking varnish), etc.

Furniture paint can make wood and bamboo furniture more beautiful and bright, improve the rough feel of the furniture itself, and make the furniture not affected by climate and dry and wet changes. It not only protects and maintains wood and bamboo furniture, but also makes the whole family life better more comfortable.
