Embodiment 1

[0029] Such as figure 1 Shown: Seismic lightweight wall panels include:

[0030] 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.

[0031] 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.

[0032] 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.

[0033] Both th...

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] Such as 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 Embodiment 1, 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 under r...

Abstract

The invention relates to the field of construction wallboards, in particular to a manufacturing method for a seismic lightweight wallboard. The manufacturing method comprises the step of die making: making a seismic frame die and a cushioning interlayer die which are used for pouring a seismic frame and a cushioning interlayer separately; the step of preparation of pouring materials: selecting ceramisite, high impact resistance polystyrene particles, polypropylene fiber and hydroxypropyl methyl cellulose, and preparing the pouring materials; the step of pouring: putting the pouring materials into the seismic frame die, and forming an upper cross beam, a lower cross beam, a left side beam and a right side beam by pouring; putting the pouring materials into the cushioning interlayer die, andforming the cushioning interlayer by pouring; and the step of wallboard making: connecting the cushioning interlayer with tongue-and-groove of the upper cross beam and the lower cross beam through tenon, and fixedly connecting the left side beam and the right side beam with the upper cross beam and the lower cross beam. According to the manufacturing method, the problems of low rigidity and poorseismic performance of an existing wallboard are solved.

Description

technical field [0001] The invention relates to the field of building wall panels, in particular to a method for manufacturing an anti-seismic lightweight wall panel. Background technique [0002] At present, the most commonly used lightweight wall panels include: lightweight energy-saving wall panels; board-based lightweight wall panels, including gypsum boards, partition wall panels, etc.; block-based lightweight wall panels, including knotted porous blocks, sintered hollow Blocks, concrete small hollow blocks, gypsum blocks, etc.; brick lightweight wall panels, including sintered porous bricks, autoclaved lime sand porous bricks, concrete bricks for roads; concrete lightweight wall panels. [0003] There is following problem in above-mentioned lightweight wallboard: [0004] 1. The size of the existing lightweight energy-saving wall panels is limited, and it is not easy to change. When in use, multiple pieces need to be glued together, and its stability and seismic perfo...
