Clean taste furniture of environmental protection and preparation method thereof
Technical field
The present invention relates to furniture processing technology field, be specifically related to clean taste furniture of a kind of environmental protection and preparation method thereof.
Background technology
In the China of 21 century, along with the further opening in market, there is the furniture of more and more new style.After basic life requirement is met, some start the impact for health of the quality focusing on life staying idle at home, particularly family product, and therefore environmental protection furniture is valued by the people gradually, and green consumption agitation has also promoted the development of environmental protection furniture.
Environmental protection furniture refers to that those are based on the basis of ecological industry, reasonable development, utilize nature material to produce can meet user's particular demands, be of value to user's health, and there is the furniture of high cultural deposits and scientific and technological content.Wherein comprise which floor implication: one, pollution-free, the toxicological harmless of furniture itself; Two, higher artistic connotation and aesthetic function to be had, echo mutually with indoor design, create a harmonious graceful telecommuting environment; Three, be convenient to reclaim, process, recycling, when furniture no longer use process time, can not to environment.
Plate fitment refers to and is main base material with wood-based plate, take plate as the assembling-disassembling furniture of basic structure.Common artificial board has glued board, core-board, shaving board, medium density fibre board (MDF) etc.Glued board (clamping plate) is usually used in making the diastrophic furniture of needs; Core-board performance affects by board core material matter sometimes; Shaving board (being again particle board, bagasse board) material is loosened, only for low-grade furniture.That cost performance is high, the most the most frequently used is medium density fibre board (MDF) (MDF).The common finishing material of plate fitment has veneer (be commonly called as and paste wooden skin), woodgrained paper (being commonly called as paster), PVC offset plate, polyester lacquer painting (being commonly called as baking vanish) etc.
Furniture lacquer can make woodenware DELICATE AND SIMPLE BAMBOO more attractive in appearance beautiful; improve furniture itself with harsh hand; make furniture not climate and Drought-wet change affect, not only play the effect of Preservation woodenware DELICATE AND SIMPLE BAMBOO, and whole family life can also be made to become more comfortable.
