Description

A kind of mute door panel

Technical field

The utility model belongs to door window device field, more specifically to a kind of mute door panel.

Background technique

With the high speed development of industrialization and urbanization, the pollution level of city noise is inevitably exacerbated, It endangers greatly through becoming the one of the mankind.Noise pollution and water pollution, atmosphere pollution are regarded as three main rings in world wide Border problem.Noise can cause a variety of diseases, and noise can also cause other damages to person other than damaging hearing.Noise may be used also With cause it is in a disturbed state of mind, be nervous, palpitating speed and blood pressure increase.Noise can also be such that the saliva of people, gastric secretion reduces, stomach Acid reduces, to be susceptible to suffer from gastric ulcer and duodenal ulcer.Some industrial noise investigation results are pointed out, are worked in high noisy condition Under steel individual and machine shop individual it is higher than the personal circulatory system disease incidence under the conditions of peace and quiet.Under strong sound, hypertension People it is also more.Many people think that the noise in the life of 20th century is to cause one of cardiopathic reason.For a long time under noisy environment Work, will also result in obstacle to nervous function.Therefore the sound insulation degree of interior door becomes essential demand, currently on the market Most of inside the door used is all hollow structure, does not fill any material, there are gaps between door-plate and doorframe, cause Soundproof effect is poor.

In view of the above-mentioned problems, be correspondingly improved such as Chinese Patent Application No.: CN201320061770.8, publication date For on July 24th, 2013, a kind of compound door plant that can be mute, including door panel are disclosed, the door panel is by sound-absorbing material system At, wherein the sound-absorbing material includes wood materials matrix and polymer damping material, the polymer damping material dispersion In the matrix of the wood materials；Two door skins, described two door skins are separately positioned on the door panel two sides. It is bonded together between the door panel and the door skin by isocyanates binder.The shortcoming of the patent exists In: isocyanates is easy that exothermic reaction occurs with water, and with certain risk, polymer damping material is expensive, and whole A compound door plant soundproof effect is poor.

Chinese Patent Application No.: CN201510146997.6, publication date are on June 10th, 2015, disclose a kind of composite door Plate, is related to construction material processing technique field, including panel, and panel includes to be spliced by two or more finger-jointed plate item Made of plate core, be respectively arranged with one layer of composite artificial board in the upper and lower surfaces of plate core, which includes two layers of base Material layer is provided with puigging between substrate layer, which is the froth bed of old foam pad mattress, substrate layer and the puigging it Between bonded with glue；In one layer of wood skin layer of composite artificial board outer cladding.The patent is disadvantageous in that: the froth bed of old foam Because of poor quality using too long, soundproof effect is general, can not be suitable for the higher place of sound isolation requirement.

Summary of the invention

1, it to solve the problems, such as
