Technical Field

The utility model relates to a sound-proof board field, concretely relates to fire-retardant acoustic baffle of environmental protection.

Background

With the increasing demand of people for living environment, various noises bring great threat to residents living in cities, especially to residents living in more complex environment.

In order to suppress the noise problem, the sound insulation device is generally used to block the transmission of noise, and the sound insulation board with wood structure is the most superior and should be the most extensive. However, the use of wood in large quantities poses a potential fire hazard and can pose a serious hazard once the wood is ignited.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a fire-retardant acoustic baffle of environmental protection to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a fire-retardant acoustic baffle of environmental protection, package rubbing board body, the plate body includes the surface course in the outside and sets gradually intermediate level and the sound absorbing layer in surface course one side, it is the array and is equipped with a plurality of through-hole on the intermediate level, the through-hole corresponds the via hole that sets up on the surface course, the inside of through-hole is provided with fire-retardant package.

Furthermore, the surface layer is formed by splicing a plurality of panels, and through holes which are uniformly formed in each panel are formed in each panel.

Further, the sound absorption layer is made of felt.

Furthermore, the surface layer, the middle layer and the sound absorption layer are sequentially bonded to form a whole.

Furthermore, the through hole is regular hexagon, the flame-retardant bag is of an annular structure, and the outer side of the flame-retardant bag is tightly attached to the inner wall of the through hole.

Further, the minimum inner diameter of the through hole is larger than the inner diameter of the through hole.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses in, set up a plurality of through-hole through being the array on the intermediate level, both sides bond with surface course and sound absorbing layer respectively, constitute wholly, after external sound passes through the via hole entering through-hole on the surface course, because the aperture of via hole is less, be difficult for after sound entering through-hole transmitting away, can only block sound absorption through the sound absorbing layer.

When the acoustical panel is burned, the flame retardant package will crack at higher temperatures and the surrounding flame will be extinguished by the escaping flame retardant, preferably a halogen based flame retardant.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides a fire-retardant acoustic baffle of environmental protection, includes plate body 1, plate body 1 includes the surface course 2 in the outside and sets gradually intermediate level 3 and the sound absorbing layer 4 in surface course 2 one side, is the array on intermediate level 3 and is equipped with a plurality of through-hole 5, and through-hole 5 corresponds the via hole 6 that sets up on surface course 2, and the inside of through-hole 5 is provided with fire-retardant package 7.

In this scheme, set up a plurality of through-hole 5 through being the array on intermediate level 3, both sides bond with surface course 2 and sound absorbing layer 4 respectively, constitute wholly, and after external sound got into through-hole 5 through via hole 6 on the surface course 2, because the aperture of via hole 6 is less, sound got into behind the through-hole 5 difficult transmission go out, can only block sound absorption through sound absorbing layer 4.

When the acoustical panel is burned, the flame retardant package 7 is cracked by a higher temperature (for example, the flame retardant is wrapped by a thin film material with a lower melting point, i.e., the flame retardant is cracked at a high temperature), and the surrounding flame is extinguished by the overflowed flame retardant, and the flame retardant is preferably a halogen flame retardant.

Surface course 2 comprises the concatenation of a plurality of panels 21, and is equipped with the via hole 6 that evenly offers on every panel 21, consequently, 2 parts of surface course are burnt out, also only need change the panel 21 that corresponds can, even if whole burnt out, it is also comparatively convenient to change.

The sound absorption layer 4 is made of felt, and has good sound absorption and blocking effects.

The surface layer 2, the middle layer 3 and the sound absorption layer 4 are sequentially bonded to form a whole body, can be manufactured in a modularized mode, and only needs to be assembled when being installed and used, so that the use is convenient.

The through hole 5 is regular hexagon, and fire-retardant package 7 is the loop configuration, and the inner wall of through hole 5 is hugged closely in the outside of fire-retardant package 7, and surface course 2, intermediate level 3 and sound absorbing layer 4 constitute honeycomb plate structure, and overall strength is higher, and weight is lighter.

The minimum internal diameter of through-hole 5 is greater than the internal diameter of via hole 6, avoids fire-retardant package 7 to spill, is favorable to improving the effect that gives sound insulation simultaneously.
