Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-3, the utility model provides a paper gypsum board gives sound insulation, including the paper backplate 20 of the gypsum board 10 that gives sound insulation and cover 10 faces of gypsum board, wrap up vacuum plate 30 in the gypsum board 10 gives sound insulation, vacuum plate 30 includes sealing layer 31, gypsum layer 32, the inside vacuum environment that is of vacuum plate 30, gypsum layer 32 constitutes for upper and lower two-layer gypsum board 321, two gypsum board 321 middle parts are connected by gypsum support frame 33, gypsum layer 32 wraps up in sealing layer 31, sealing layer 31 top surface and the equal interval arrangement in bottom surface have the fixed block (not shown in the figure, the height and the size of fixed block can be decided according to the paper gypsum board thickness contingency of customization. During the use, because be vacuum environment in the vacuum panel 30, consequently this embodiment is when as indoor partition wall, can separate the sound propagation in two adjacent spaces, reaches good syllable-dividing demand, and simultaneously, the vacuum panel 30 of this embodiment uses gypsum layer 32 as the skeleton, keeps vacuum environment with sealing layer 31 is sealed for this embodiment can keep long-term syllable-dividing effect. The paper backplate 20 of both sides can be contradicted to the fixed block, reserves the space for pouring of gypsum thick liquid for vacuum plate 30 can be wrapped up by the gypsum thick liquid completely.

Because gypsum layer 32 is the intermediate structure, plays the effect of supporting sound insulation paper surface gypsum board, for the intensity that improves this embodiment paper surface gypsum board, this embodiment is in gypsum support frame 33 left and right sides symmetrical arrangement second gypsum support frame 34, and the cross-section of second gypsum support frame 34 is the V-arrangement, and the three extreme point of second gypsum support frame 34 all links firmly with gypsum layer 32 inner chamber wall. Utilize gypsum support frame 33, second gypsum support frame 34 to support gypsum layer 32 structure, prevent that the thistle board from keeping the vertical plate type in subsequent use, be difficult for the compressive deformation.

In order to ensure that the gypsum slurry flows to the bottom surface of the vacuum plate 30 quickly when the vacuum plate 30 is poured, and the vacuum plate 30 is wrapped, the top surface of the gypsum layer 32 in this embodiment is in an arch shape with a middle height and a gradually reduced periphery. The arched top surface of the gypsum layer 32 can provide positive flow guidance as the gypsum slurry is poured onto the vacuum plate 30.

In order to realize the vacuum environment in the vacuum plate 30, in the embodiment, an air extraction hole 35 is formed in one side of the vacuum plate 30, a sealing plug 36 is filled in the bore of the air extraction hole 35, and the sealing plug 36 is bonded with the sealing layer 31 to form a fixed connection. During preparation, the space in the sealing layer 31 can be pumped through the opened pumping hole 35 so as to achieve a vacuum effect, and then the sealing plug 36 is used for sealing.

In order to achieve a better sealing effect, the sealing layer 31 of this embodiment may be made of any one of PE and PVC.

The production method of the sound-insulation paper-surface gypsum board comprises the following steps:

s1, pouring and curing gypsum slurry to integrally form a gypsum layer 32 for clamping the gypsum support frame 33 and the second gypsum support frame 34, wrapping and sealing a sealing film along the surface layer of the gypsum layer 32 to form a sealing layer 31, forming an extraction hole 35 in the gypsum board 321 on one side penetrating through the gypsum layer 32, and sealing the extraction hole 35 by using a sealing plug 36 and bonding and fixedly connecting the extraction hole 35 with the sealing layer 31 after the extraction is performed to the vacuum state in the vacuum board 30;

s2, laying the vacuum plate 30 on the paper protection plate 20, enabling the fixing block to support the paper protection plate 20 in an abutting mode, and pouring gypsum slurry until the gypsum slurry on the top surface of the vacuum plate 30 covers the fixing block;

and S3, covering the paper guard board 20 on the other side when the gypsum slurry is wet, and drying and curing the gypsum slurry in a drying box to obtain the finished product of the sound-insulation paper-surface gypsum board.

The production method of the sound-insulation paper-surface gypsum board is simple and convenient, is suitable for automatic flow line production, and is high in production efficiency.
