Embodiment 1

[0051] A method for manufacturing an environmentally friendly, energy-saving, fire-resistant, and electromagnetic-radiation-resistant composite door, including preparing flame retardants, wood fibers, carbon fibers, adding urea-formaldehyde glue, waterproofing paraffin chemical additives, etc., preparing flame retardants, mixing fibers with glue, and laying layers. Finally, the environment-friendly, energy-saving, fire-proof, anti-magnetic radiation, and anti-static density board is formed at one time by high temperature and high pressure, which is characterized in that it specifically includes the following steps:

[0052] The first step: preparation of flame retardant:

[0053] After mixing boron compounds (borax, zinc borate) and amine compounds (ethanolamine, dimethyl ethanol), raise the temperature to 60-120°C, hold the temperature for 40-60 minutes, cool down to below 30°C, and make A polymer ;

[0054] Add titanium sulfate or zinc oxide to the aqueous solution ...

Embodiment 2

[0066] In the first step, the preparation of the flame retardant: the flame retardant of the present invention is a resin type flame retardant, with boron, phosphorus, ammonium, nitrogen, titanium, silicon, zinc, aldehyde compounds, phosphorus compounds It decomposes into pyrophosphoric acid, dehydrates and carbonizes cellulose and hemicellulose into non-activated carbon under the catalysis of titanium and zinc, greatly reduces the heat release rate and heat release of the plate, promotes the interruption of combustion reaction, and prevents the spread of combustion; phosphorus compounds in nitrogen, Under the action of titanium and zinc compounds, the flame retardant effect will be greatly improved;

[0067] Nitrogen compounds will improve the flame retardant effect of phosphorus compounds; when a fire occurs, the flame retardant will release ammonia to reduce the oxygen content in the combustion body, causing the combustion body to be interrupted due to the lack of oxidan...

Embodiment 3

[0076] Preparation of wood fiber in the second step: use waste wood from forest trees, scraps from furniture factories, wooden door factories, floor factories, wood processing factories, veneer factories, waste wood, branch wood, secondary small-diameter wood, Artificial high-yield forests and other woods are used as raw materials, and the required wood fibers are prepared by cutting, planing or chipping, sorting, washing, softening, and heat grinding.

Abstract

The invention discloses a manufacturing method for an environment-friendly energy-saving fireproof anti-electromagnetic radiation composite door. The method comprises the steps that fire retardants, wood fibers, carbon fibers, urea-formaldehyde glue, waterproofing agent of paraffin, chemical addition agents and the like are adopted, and an environment-friendly energy-saving fireproof anti-electromagnetic radiation antistatic density board is formed at a time through high temperature and high pressure after preparation of the fire retardants, fiber glue mixing and layered pavement. The method has the beneficial effects that 1, the mechanical property is improved; 2, the good fireproof performance is achieved and meets the standard of the level B or the level C of GB8264; 3, the anti-electromagnetic radiation antistatic and electric conduction functions are achieved; 4, the formaldehyde emission is lower than the national standard; 5, sufficient reuse of three-remains waste wood of forests and industrial waste-grade carbon fibers is achieved, the waste material is changed into the things of value, a large number of forest resources are saved, the cost is reduced, and the environment is protected effectively.

Description

technical field [0001] The invention belongs to the manufacturing technology of composite doors, and in particular relates to a manufacturing method of an environment-friendly, energy-saving, fire-proof, electromagnetic-radiation-proof composite door. technical background [0002] The raw material of the composite door is generally a combination of density fiber board and wood frame, and density fiberboard and wood frame are both a kind of man-made board, and density fiber board is composed of wood fiber and glue, which are organic combustible materials, which are easy to cause fire and have potential safety hazards , Seriously endangering people's lives and property, is an important factor that directly affects my country's economic development and social stability. [0003] With the rapid development of the electronics industry and the widespread use of various electronic products, magnetization, static electricity, and radiation are ubiquitous in people's daily life and wo...
