Embodiment 1

[0028] like figure 1 Shown: Seismic ceramsite lightweight wall panels include:

[0029] A rectangular anti-seismic frame, the anti-seismic frame includes an upper beam 1, a lower beam 2, a left beam 4 and a right beam 3, the upper beam 1 is provided with a first dovetail groove 11, and the lower beam 2 is provided with a second dovetail groove twenty one.

[0030] The cushioning interlayer 5, the upper end of the cushioning interlayer 5 is provided with a first dovetail tenon 51 used in conjunction with the first dovetail groove 11, and the lower end is provided with a second dovetail tenon 52 used in conjunction with the second dovetail groove 21.

[0031] The upper beam 1 and the lower beam 2 are connected with the first dovetail tenon 51 and the second dovetail tenon 52 of the shock-absorbing interlayer 5 through the first dovetail groove 11 and the second dovetail groove 21 respectively. The joints are coated with glue-mixed graphite with a thickness of 3-7mm.

[0032] ...

Embodiment 2

[0042] Compared with Embodiment 1, this embodiment differs only in that the structure of the filling block in the wallboard manufacturing step in this embodiment is different.

[0043] like figure 2 As shown: the filling block in this embodiment includes a glass tube inner layer 61 and a viscoelastic outer layer 62, the glass tube inner layer 61 and the viscoelastic outer layer 62 are both closed spaces, and the glass tube inner layer 61 is placed with peroxide, viscoelasticity Esters and fluorescent dyes are placed between the outer layer 62 and the inner layer 61 of the glass tube. Specifically, sodium peroxide is used for the peroxide, ethyl acetate is used for the ester compound, and red fluorescent dye is used for the fluorescent dye.

Embodiment 3

[0045] Compared with the first embodiment, this embodiment differs only in that in the pouring step, when pouring the cushioning interlayer, a closed chamber is provided in the cushioning interlayer, and a shear thickening liquid is placed in the chamber.

[0046] Concrete, the preparation method of shear thickening liquid is:

[0047] Add a 20 wt% isocyanate solution and a catalyst to a 35 wt% polyethylene glycol solution, pre-react for 30-50 minutes under reflux conditions, then add a 15 wt% cellulose acetate solution, and mix well React at 80°C for 1-3 hours, distill off the solvent under reduced pressure to obtain the base liquid;

[0048] Add ethyl silicate to tetrapropylammonium hydroxide saturated liquid with a concentration of 25wt%, stir and react at 80°C for 1-3 hours to obtain an additive solution;

[0049] Mix the base liquid and the additive liquid, react at a temperature of 140-160°C and a pressure of 0.5-0.6Mpa for 18-24 hours, and finally distill off the water...

Abstract

The invention relates to the field of building wall boards, in particular to an anti-seismic ceramsite lightweight wall board. The anti-seismic ceramsite lightweight wall board comprises an anti-seismic framework and a seism cushioning interlayer, wherein the anti-seismic framework is a rectangular framework and comprises an upper cross beam, a lower cross beam, a left side beam and a right side beam; both the upper cross beam and the lower cross beam are provided with grooves; tenons are arranged on the seism cushioning interlayer; the seism cushioning interlayer is connected with groove andtongues of the upper cross beam and the lower cross beam through the tenons; the anti-seismic framework and the seism cushioning interlayer are formed by casing a pouring material; the pouring material is prepared from ceramsites, high impact-resistance polystyrene particles, polypropylene fibers and hydroxypropyl methyl cellulose. By adopting the anti-seismic ceramsite lightweight wall board disclosed by the invention, the problems that an existing wall board has low rigidity and poor seismic resistance can be solved.

Description

technical field [0001] The invention relates to the field of building wallboards, in particular to an anti-seismic ceramsite lightweight wallboard. Background technique [0002] From the survey of major earthquake disasters around the world, it can be found that more than 95% of casualties are caused by damaged or collapsed buildings, so improving the seismic performance of buildings is one of the main measures to improve the comprehensive defense capacity of cities. The seismic performance of buildings depends on the seismic performance of wall panels. Traditional wall panels are generally made of brick walls with mixed structures. Nowadays, traditional wall panels are slowly being replaced by lightweight wall panels. Lightweight wall panels are due to Its light weight, good sound insulation effect and other advantages are favored by people. [0003] At present, the most commonly used lightweight wall panels include: lightweight energy-saving wall panels; board-based light...
