Embodiment Construction

[0020] A kind of fly ash board interlayer sound insulation door panel, characterized in that it includes a fly ash board, a sound insulation material, and a wood board, the fly ash board contains wood fibers, the sound insulation material is a sound insulation felt, and the wood board refers to joints. One or more of board, veneer, solid wood board, blockboard, particle board, density board, plywood, and fiberboard.

[0021] The arrangement of the fly ash board, the sound insulation material and the wood board is as follows: the sound insulation material is on both sides of the fly ash board, the wood board is on the outside of the sound insulation material, the total number is odd, and the outermost is the wood board.

[0022] The thickness of the fly ash board is 8-10mm; the thickness of the wood board is 3-5mm, and the thickness of the sound insulation material is 3-5mm.

[0023] The steps of its preparation method are:

[0024] 1. Grind the sintered fly ash boar...

Abstract

The invention discloses a coal ash plate interlayer sound insulation door sheet and a manufacturing method thereof. The door sheet comprises a coal ash plate, a sound insulation material, and a wood board. The coal ash plate contains wood fibers. The sound insulation material is a sound-proof felt. The wood board is one or more selected from finger-joint board, wood veneer, solid board, core-board, chipboard, density board, plywood, and fibreboard. The door sheet is manufactured through respective tailoring, cutting, polishing, gluing, and a hot pressing technology. The coal ash plate and the wood board are combined to enhance flintiness of a wooden door, and use ratio of coal ash is improved. The sound-proof felt arranged between the door sheets can absorb large amount of audio frequency. Since the coal ash plate is large in density, and hard in material, and the surface is polished into a regular wavy form, so audio frequency which is not absorbed by the sound-proof felt can be reflected, so as to actually effectively improve sound-absorbing and sound insulating effects.

Description

technical field [0001] The invention relates to a door panel and a manufacturing method thereof, in particular to a fly ash board interlayer soundproof door panel and a manufacturing method thereof. Background technique [0002] my country is a large coal-producing country, and coal is used as the basic fuel for electric power production. my country's energy industry has developed steadily, with an annual growth rate of 7.3% in power generation capacity. The rapid development of the power industry has brought about a sharp increase in the amount of fly ash discharged. The total amount of fly ash emitted by coal-fired thermal power plants has increased year by year. In 1995 The annual fly ash discharge amounted to 125 million tons, about 150 million tons in 2000, and will reach 300 million tons by 2010, which has caused enormous pressure on my country's national economic construction and ecological environment. On the other hand, our country is a country with limited resource...
