Abstract

The invention discloses a preparation method for a fibreboard. The preparation method comprises the following steps of: uniformly mixing fibres with carbon particles accounting for 3-5% of the total mass, and then preparing the fibreboard via needling, heat setting and rolling. According to the preparation method disclosed by the invention, during a preparation process, an adhesive is not needed; the fibreboard is environment-friendly, and furthermore, the carbon particles in the fibreboard can also be used for effectively absorbing hazardous substances volatilized and released in a room. Via the needling procedure of the preparation method disclosed by the invention, the opportunity that the carbon particles are in contact with the outside is increased; during hot-pressing, low-melting-point polyester staple fibres are melted, and capable of being integrally bonded with conventional polyester staple fibres, polyamide fibres or carbon fibres and the carbon particles, thus ensuring no falling-off of the carbon particles during a use process; the carbon particles can be in contact with more air via pores among the fibres or gaps between the carbon particles and the fibres, thus increasing the adsorption efficiency of the fibres; and an adsorption experiment for formaldehyde proves that the adsorption efficiency of the fibres achieves more than 85%.

Description

technical field [0001] The invention relates to a method for preparing an environment-friendly plate, in particular to a method for preparing a fiberboard capable of absorbing harmful substances. Background technique [0002] In today's world, "indoor air pollution" has become the third environmental pollution after "soot pollution" and "photochemical smog pollution". Foreign studies have found that there are more than 500 kinds of volatile organic compounds in the indoor air, among which there are more than 20 kinds of carcinogens and more than 200 kinds of pathogenic viruses. The most harmful ones are: radon, formaldehyde, benzene, ammonia, esters, and trichlorethylene. Studies have shown that indoor air pollution is 2 to 5 times more serious than outdoor air, and can reach 100 times in special cases. [0003] According to statistics, nearly half of the world's people are exposed to indoor air pollution. Indoor environmental pollution has caused 35.7% of respiratory dise...
