Abstract
The invention discloses a production method of steel soundproof doors. The production method comprises a door frame and a door leaf, the door leaf comprises an inner door panel, an outer door panel, and a frame (8) connecting the inner door panel and the outer door panel, the inner door panel (1), a first fireproof layer (2), a first soundproof layer (3), a core layer (4), a second soundproof layer (5), a second fireproof layer (6), the outer door panel (7) are sequentially arranged from inside to outside. The inner door panel (1) and the outer door panel (7) are each made of steel panels. Through the multi-layer design and design of the production methods of each layer, the steel soundproof doors produced are not only good in sound insulation, door strength and fireproof effect has been improved, and the needs of specific occasions are fully met.
Description
technical field [0001] The invention relates to the technical field of doors, in particular to a method for preparing a steel soundproof door. Background technique [0002] The rapid development of industry and urbanization has inevitably aggravated the degree of noisepollution. [0003] Noise from various occasions in life is exhausting. The most direct harm of noise to the human body is hearing damage, and then acts on the central nervous system of the brain, causing people to have symptoms of neurasthenia such as headache, brain swelling, tinnitus, insomnia, general fatigue and weakness, and memory loss. Compared with people who work in a high-noise environment for a long time, the incidence of hypertension, arteriosclerosis and coronary heart disease is 2-3 times higher than that in a low-noise environment. Noise is extremely harmful to the fetus. High-decibel noise can damage the auditory organs of the fetus, and it can also cause dysfunction of the endocrine gland...
