Description

A kind of soundproof door
Technical field
The present invention relates to a kind of soundproof door.
Background technology
For from the effect of door, mainly door can be divided into gate, entering house door, interior door, explosion proof door, blast-resistant door, fire prevention Door etc..Entering house door is also referred to as antitheft door, and most of houses are assembled with entering house door when being completed, some consumer for safety and other From the standpoint of can be replaced.Entering house door mainly has clean steel matter entering house door and armoured door.Armoured door is high-grade entering house door, main Wanting feature is not use traditional surface treatment method, but increases by one layer of wooden facing on the surface of steel entering house door, the most both Ensure that the security factor of entering house door, substantially increase again the class of door, at the same time it can also be preferably coordinate with interior decoration. For entering house door, consumer be more interior door, the kind of interior door is the most various, Ye Shiling consumer The kind felt at a loss.Following length mainly introduces classification and the feature of interior door.
Common Solid Door can divide two kinds, and one is assembled with common log (such as Masson Pine, pear wood etc.), this door Good environmental protection, technological requirement is high, but the timber owing to selecting is bad, and product is not to improve grade very much, and also one is to make Assembled with full solid wood finger-jointed plate, this door feature of environmental protection is also good, but production technology is fairly simple, and style is not the abundantest, Outward appearance is not fine, and why common Solid Door exists is primarily due to its strong environmental consciousness having catered to consumer, its Product there is no much saving graces.
Solid wood composite door is the main flow in following timber market, and solid wood composite door creates sense free from worldly cares because of its fine technique Seeing, effect presses on towards log door；Because the design of its science achieves stablizing of quality, use value exceeds log door, and above-mentioned is several Plant interior door and all can be referred to as medium-to-high grade interior door.
Current existing door installs inconvenience, and soundproof effect is bad, and sealing is the highest.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of easy for installation, and soundproof effect is good, the soundproof door that sealing is high.
For solving the problems referred to above, the present invention adopts the following technical scheme that
