Description
Technical field
The invention belongs to technical field of artificial boards, it is related to a kind of fiber bamboo wood board and preparation method thereof, specifically
It is related to a kind of formaldehydeless bamboo wood board of fire retardant, anticorrosive and preparation method thereof.
Background technique
As the improvement of people's living standards, the finishing in the places such as people live to it or handle official business, activity also proposed more
High requirement, not only require it is beautiful and generous, it is modish fashion, naturally succinct, but also require health environment-friendly.And currently, China is raw
The fiberboard overwhelming majority of production uses Lauxite, react by certain mol proportion mixing generating ureaformaldehyde tree with urea by formaldehyde
Rouge.Using common Lauxite as free formaldehyde is remained in the fiberboard plate of adhesive, the body for endangering people is strong
Health, formaldehyde is to all irritating effect of the schneiderian membrane of human body, retina, respiratory tract and liver, for a long time in high-concentration formaldehyde content
Work and life in environment will appear the formaldehyde poisonings symptom such as allergy, dizziness, fatiguability, vomiting, and serious person can cause a disease, even
It is carcinogenic.Form aldehyde release mainly from：1. the free formaldehyde of end reaction in Lauxite；2. in resin unstable molecule in hot pressing or
Formaldehyde is released in plate use process again.
Common wood plank currently on the market, burst size of methanal can largely reach national standard, and (country goes out within 2001
Platform《Form aldehyde release limitation in indoor hardware fitting wood-based plate and its product》It is provided in GBl8580-200l, free formaldehyde
Burst size≤1.5mg/L, can be directly used for interior, and free formaldehyde release≤5.0mg/L finishing material has to pass through facing
Could be used for interior), but there are the release of nuisance, finishing material or use used in the places such as household, office, activity
Product, such as floor, furniture, wallpaper, smallpox, Wood-door window, coating, although the nuisance release of each product can reach national standard
It is required that but several finishing materials be used in same site space together, the nuisance released jointly may greatly surpass
National standard out, this will seriously threaten the health of numerous people.
