Children's antibacterial damage resistant furniture and preparation method thereof
Technical field
The present invention relates to furniture processing technology fields, and in particular to a kind of children's antibacterial damage resistant furniture and its preparation side
Method.
Background technology
In the China of 21 century, with the further opening in market, there is the furniture of more and more new styles.In base
After this life requirement obtains satisfaction, some start to focus on the quality of home life, and particularly family product is for health
It influences, therefore environmentally friendly furniture is valued by the people gradually, green consumption agitation has also promoted the development of environmentally friendly furniture.
On the basis of environmentally friendly furniture refers to those based on ecological industry, reasonable development is produced using nature material
Disclosure satisfy that user's particular demands, be beneficial to user's health, and the family with high cultural deposits and scientific and technological content
Tool.Wherein include several layers of meanings:First, furniture itself is pollution-free, nonhazardous;2nd, there is higher artistic connotation and aesthetic function,
It is mutually echoed with indoor design, creates a harmonious graceful telecommuting environment;3rd, it is main convenient for recycling, handling, recycling
Tool is not used when being handled, and not can cause environmental pollution.
Plate fitment refers to that using wood-based plate be main base material, the assembling-disassembling furniture using plate as basic structure.It is common
Artificial board have glued board, core-board, particieboard, medium density fibre board (MDF) etc..Glued board (clamping plate) is usually used in making needs
The furniture of flexural deformation;Core-board performance is influenced sometimes by plate core material;Particieboard (being called particle board, bagasse board) material
It is loose, it is only used for low-grade furniture.Cost performance highest, the most commonly used is medium density fibre board (MDF) (MDF).The common facing of plate fitment
Material has veneer (being commonly called as patch wood skin), woodgrained paper (being commonly called as paster), PVC offset plates, polyester lacquer painting (being commonly called as baking vanish) etc..
Furniture lacquer can make woodenware DELICATE AND SIMPLE BAMBOO more attractive beautiful, improve furniture per se with harsh hand, make furniture not
Climate is influenced with Drought-wet change, not only acts as the effect of Preservation woodenware DELICATE AND SIMPLE BAMBOO, and can also give birth to entire family
It is living to become more comfortable.
The immunity of children, self-protection ability are all lower than being grown up, as the children furniture contacted for a long time with children, one
Denier there are hidden danger, will undoubtedly evolve into product quality and environmental-protecting performance etc. and be imbedded in " time bomb " of children at one's side,
Children may be damaged at any time.For the general status of current domestic children furniture industry, big and small brand adds
Can do not get up any more 200, but product is irregular, unification than more serious, the feature of environmental protection, security also in the prevalence of
Defect.
