Abstract
The invention discloses a bamboo fiber plate. The plate is mainly prepared by 20-60% of bamboo fibers, 20-40% of hydrotalcite, 20-40% of adhesive and 10-40% of epoxy resin. According to the bamboo fiber plate, the hydrotalcite is taken as an additive, and the bamboo fiber plate has an excellent flame-retardant effect; when the bamboo fiber plate is partially damaged while meeting sudden combustion and has a self-recovery capacity, the formaldehyde content is very low through detection, and is green, safe and environmental-friendly, therefore the bamboo fiber plate has a better practical application value.
Description
Technical field
The present invention relates to environment-friendly type household material and manufacture field, specifically a kind of bamboo fiberboard.
Background technology
Along with the raising of people's living standard, house ornamentation decoration has become a kind of necessity.At present, rapidly, especially interior decoration and decoration aspect, needs to consume a large amount of fitment material for families in fitment material for family development.Current indoor fitment material for family is mainly divided into pure inorganic plate, timber, organic board, textile material, composite board, and because the easy moisture absorption of timber, perishable, easy trick are damaged by worms and soaked rear defect easy to crack, its application scenario is restricted.And inorganic plate, organic board with the some shortcomings of textile material due to himself, the application demand of high requirement cannot be met.The appearance of composite can solve a lot of demand, and some not only has the advantage of traditional material, also has the function of more novelties simultaneously, but while meeting application demand, bring again unavoidable problem in the industry, adding of laminated dose or adhesive, residues of formaldehyde problem can be brought.
Current research shows that formaldehyde has become first kind carcinogen.Formaldehyde causes the nasopharyngeal carcinoma of the mankind, CARCINOMA OF THE NASAL CAVITY and nasal sinus cancer, and can cause leukaemia.According to state compulsory standard, after closing the doors and windows 1 hour, in every cubic metre of room air, burst size of methanal must not be greater than 0.08 milligram; As reached 0.1-2.0 milligram, the normal person of 50% can smell foul smell; Reach 2.0-5.0 milligram, eyes, tracheae will be subject to intense stimulus, occur sneezing, the symptom such as cough; Reach more than 10 milligrams, expiratory dyspnea; Reach more than 50 milligrams, can the critical illness such as pneumonia be caused, even cause death.
In addition, because fire happens occasionally, and the inflammability of domestic environment material determines degree disaster-stricken when fire occurs to a certain extent, and the household material with fire resistance can prevent, stop spreading of fire.
Therefore, content of formaldehyde compound fitment material for family that is low, that have fire resistance is the key solving existing Indoor Environment Safety and Its sex chromosome mosaicism.
Summary of the invention
For solving existing fitment material for family performance and safety issue, the invention provides a kind of bamboo fiberboard.This bamboo fiberboard not only function admirable, and content of formaldehyde is extremely low, is a kind of excellent environmental protection fitment material for family.
The technical scheme that the present invention solve the technical problem is: design a kind of bamboo fiberboard, and this plate is prepared primarily of bamboo fibre, hydrotalcite, adhesive and epoxy resin.
The preparation process of described bamboo fibre is cooked by natural bamboo chip bamboo fibre sander long for 7-8 centimetre be polished into cotton shape and get final product.
Described hydrotalcite grinds to form 200-400 order.
Described adhesive is polyvinyl alcohol.
Described epoxy resin is commercially available.
Described hydrotalcite is calcareous type hydrotalcite.
The preparation process of described bamboo fiberboard: bamboo fibre, hydrotalcite are taken corresponding component according to weight ratio, then mixes; The adhesive of respective amount is put into water, and heating makes it dissolve completely in water, adds the epoxy resin of corresponding proportion after becoming homogeneous pasty state; The weight ratio of water and adhesive is (3.5-6): 1; The mixture of bamboo fibre and hydrotalcite and the binder combination that adds epoxy resin are put into agitator and carries out mix and blend, after stirring, mixture paste is put in the mould of prefabricated board, by surface flattening, compacting, then carry out dehydrating and curing under being placed on long wave ultraviolet light, after completing, namely obtain described bamboo fiberboard; Described bamboo fibre addition 20-60%, hydrotalcite addition 20-40%, adhesive addition 10-40%, epoxy resin addition 5-15%.
Preferably, described bamboo fibre addition 25-50%, hydrotalcite addition 25-40%, adhesive addition 15-40%, epoxy resin addition 5-13%.
The present invention compared with prior art, its beneficial effect is: bamboo fiberboard of the present invention adopts hydrotalcite as additive, there is superior flame retardant effect, when running into unexpected burning local damage, there is again self-healing ability, content of formaldehyde is extremely low, green, safety, environmental protection, have good actual application value.
