Definitions
- the invention relates to the technical field of flame retardant panels, in particular to a (bamboo and grass) fiber siliconized wood-based panel and a preparation method thereof.
- bamboo and wood fiber is a kind of cheap and abundant raw material, which is widely used in flame retardant boards, and has the advantages of low price, light weight and convenient production.
- bamboo and wood fibers need to be bonded by adhesives to form boards.
- adhesives generally contain toxic substances such as formaldehyde, and the release time of formaldehyde is very slow, which is harmful to human health and affects the living environment.
- flame retardants are generally halogen flame retardants. Halogen flame retardants are low in price, good in stability, less in addition, and have good compatibility with adhesives, and can maintain the original physical and chemical properties of flame retardant products. performance.
- the halogen flame retardant emits toxic smoke and gas when it is flame retardant, thus endangering the environment and human health.
- the low ignition point of bamboo and wood fiber itself due to the low ignition point of bamboo and wood fiber itself, it is easy to burn and be bitten by mosquitoes, and has poor sound insulation effect and poor thermal insulation performance.
- bamboo and wood fibers have poor water resistance, are prone to mold growth, are eaten by insects, and have poor durability.
- the present invention provides a (bamboo and wood) fiber siliconized wood-based panel and a preparation method thereof, which solves the problem that the existing bamboo and wood fiber panels release toxic gases such as formaldehyde, which are harmful to human health, have poor water resistance, and are easy to be attacked by insects. Moth bites, not durable and other technical issues.
- the technical scheme of the present invention is as follows: a kind of (bamboo and grass) fiber siliconized wood-based panel, including each component of following mass percentage:
- the (bamboo and grass) fiber siliconized wood-based panel includes each component in the following mass percentages:
- the (bamboo and grass) fiber siliconized wood-based panel includes the following components by mass percentage:
- the tourmaline powder has a particle size of 10 ⁇ m to 300 ⁇ m.
