Embodiment Construction

[0020] A fly ash board interlayer bulletproof door panel is characterized in that it includes a fly ash board, a wood board and a bulletproof layer, the fly ash board contains wood fibers, and the wood board refers to a joint board, veneer, solid wood board, thin One or more of wood board, particle board, density board, plywood, and fiberboard, and the bulletproof layer is composed of steel plate and Kevlar.

[0021] The arrangement of the fly ash boards, planks and bulletproof layers is as follows: the bulletproof layers are on both sides of the fly ash boards, the planks are outside the bulletproof layers, the total number is an odd number, and the outermost is a plank.

[0022] The thickness of the fly ash board is 3-10mm; the thickness of the wood board is 3-5mm, the thickness of the steel plate is 8-10mm, and the thickness of the Kevlar is 2-4mm.

[0023] The steps of its preparation method are:

[0024] 1. Grind the sintered fly ash board to a specified thickn...

Abstract

The invention discloses a coal ash plate interlayer bulletproof door sheet and a manufacturing method thereof. The door sheet comprises a coal ash plate, a wood board, and a bulletproof layer. The coal ash plate contains wood fibers. 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 bulletproof layer is formed by a steel plate and a Kevlar. The door sheet is manufactured through respective tailoring and cutting, polishing, winding, and wrapping, bonding by an environmentally-friendly glue, and hot-pressing by a hot press. 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, and hardness and tenacity of the coal ash plate are very strong. In a production process of the door sheet, the steel plate and the Kevlar are added, so that bulletproof performance of the door sheet is greatly enhanced.

Description

technical field [0001] The invention relates to a door panel and a manufacturing method thereof, in particular to a fly ash board interlayer bulletproof 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 resourc...
