Description
Technical field
The present invention relates to building material technical field, especially a kind of lightweight hybrid sandwich wall panel and manufacturing process thereof.
Background technology
The advantages such as lightly constructed and simply equipped building is simple and convenient with it, the low easy construction of cost more and more accept by people, and the employing of its body of wall of this lightly constructed and simply equipped building is Light trabs, the usual inside of Light trabs in the market has insulation layer, as polystyrene, hard-foam polyurethane etc., although heat-insulating property is pretty good, its fireproof performance can only reach B level; What have has then added rock wool, slag silk floss etc., although there is certain fireproof performance, this wallboard shrinks at moisture laden air and the easy sedimentation of water volume, causes departing from wallboard top layer, thus affects wallboard use.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome the technical problem that in prior art, Light trabs fire-protection rating is low, heat insulation effect is poor, provide a kind of lightweight hybrid sandwich wall panel, fire-protection rating is brought up to A1 level by B level by it, possessed again good heat-insulating property, and whole wallboard is slim and graceful simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of lightweight hybrid sandwich wall panel, comprise metal shell, metal shell is made up of side fascia and inner wall panel, cement foamed layer is filled with in described metal shell, between described cement foamed layer and side fascia, there is outer adhesive linkage, between cement foamed layer and inner wall panel, there is interior adhesive linkage.Cement foamed layer proportion is low, and density is 0.2 ~ 0.8g/cm
3, a large amount of micropores in the middle of it form good sound-insulating layer, and cheap, simultaneously outside plate and the higher metal of inner panel working strength, therefore its strength character is better, can be widely used in temporary building and simple construction.
For realizing quick assembling when wallboard is installed, described side fascia one end and inner wall panel one end form cambered outwards convex male end mutually, the side fascia other end and the inner wall panel other end form the concavity female end concaved mutually, and described convex male end and concavity female end are that male and female matches grafting when plate is connected with plate.
For the intensity of Reinfored wallboard edge, and strengthen the sealing of connection, the side fascia at described convex male end place has the first fold of one section of stepped distribution, the tendency of described first fold is for inwardly to successively decrease step by step, the side fascia at described concavity female end place has the second fold of one section of stepped distribution, the tendency of described second fold is for outwards to successively decrease step by step, and between wallboard during male and female pairing grafting, described first fold and the second fold dock mutually.
PU material is filled with between described cement foamed layer and concavity female end, the PU material edge sealing of the underrun filling of concavity female end, side fascia and the inner wall panel of described convex male end end face are fitted for compressing, and be filled with PU material between described cement foamed layer and convex male end, PU is polyurethane.
In order to improve wall plate structure intensity, described outer adhesive linkage and interior adhesive linkage are PUE elastic body, PUE refers to polyurethane elastomer, it is a kind of sprayed on material that multiple macromolecular material is polymerized, there is high adhesive strength, and pliability is good, the corrosion of wear-resisting antiskid, water-fast ageing-resistant, resistance to every medium.
The thickness of described outer adhesive linkage and interior adhesive linkage is 0.05 ~ 0.10mm, the adhesive linkage of this thickness can reach maximum shear strength, adhesive linkage in use, split immediately after bonding portion sprays paint with PUE elastic body within the working life of defined is also clamped, and uses even contact pressure guarantee is obtained optimum viscosity intensity in bonding site.
In order to improve wallboard combination property, the thickness of described cement foamed layer is 3 ~ 8cm, and the thickness of described side fascia and inner wall panel is 0.20 ~ 0.80mm.
Further, for making wallboard performance reach best, the thickness of cement foamed layer is 4cm, and the thickness of side fascia and inner wall panel is 0.40mm, and the thickness of outer adhesive linkage and interior adhesive linkage is 0.06mm.Wallboard of the present invention performance comprises environmental protection, insulation, sound insulation, light specific gravity, cost is low, resilience is strong, anti-wear performance is good, toughness is excellent, heat resistance is good, moisture-proof is strong.
Manufacture a technique for lightweight hybrid sandwich wall panel, comprise following steps:
A, sheet metal is made inside and outside wall board respectively through punching press, by the PUE elastic body that on side fascia and inner wall panel tow sides, rendering last layer 5um is thick respectively, 4 ~ 8 seconds are incubated at 250 DEG C, and then essence is coated with the thick PUE elastic body of last layer 15um, at 250 DEG C, be incubated 4 ~ 8 seconds, obtain color steel thus;
B, by 66%-67%(percentage by weight) cement and 30%(percentage by weight) flyash mixing, and then be mixed into 3%-4% polystyrene (percentage by weight), and add blowing agent and obtain cement foamed layer; Blowing agent in this step can select physical blowing agent, such as, have lower boiling alkane and fluorocarbons.
C, process in step a is obtained color steel again coat PUE elastic body on bonding face, as adhesive linkage inside and outside bonding;
D, the cement foamed layer obtained in step b to be coated between metal shell that the inside and outside wall board that obtains in step c forms, and to make inside and outside wall board firmly bonding with cement foamed layer by laminating machine compacting;
E, after steps d process, again PU material is filled in metal shell except in other spaces outside cement foamed layer by high pressure foaming machine, the connection of convex male end place inside and outside wall board is directly compressed edge sealing by laminating machine, and the connection of concavity female end place inside and outside wall board is carried out edge sealing by the PU material of filling, can lightweight hybrid sandwich wall panel be obtained.
As preferably, the amount of polystyrene is 4%(percentage by weight), add a small amount of polystyrene in cement foamed layer after, the weight of cement foamed layer can be made, but the performances such as fire prevention do not reduce.
Above-mentioned PUE elastic body is made by oneself by Wujiang Huifeng Material Technology Co., Ltd., its concrete preparation process is open at application number 201110270658.0, those skilled in the art can prepare voluntarily, adopt this kind of elastomeric strong adhesion of PUE, what can ensure between inside and outside wall board with cement foamed layer is bonding.
The invention has the beneficial effects as follows, the present invention instead of organic plastics warming plate with this incombustible material of ultra-light foamed cement, reach with its substantially suitable coefficient of thermal conductivity while, solve the nonfireproof shortcoming of metal organic plastics insulation sandwich board; Overcome after metal surface rock wool sandwich panel makes moist that sedimentation contraction, volume reduce, coefficient of thermal conductivity improves shortcoming, most importantly the present invention eliminates the application of polyurethane insulation coating, directly adopts cement foamed layer alternative.
