Description

Lightweight mixed type laminated wall panel and manufacturing process thereof
Technical field
The present invention relates to building material technical field, especially a kind of lightweight mixed type laminated wall panel and manufacturing process thereof.
Background technology
Advantages such as lightly constructed and simply equipped building is simple and convenient with it, the low easily construction of cost are more and more accepted by people, and its body of wall employing of this lightly constructed and simply equipped building is Light trabs, the common inside of Light trabs in the market has insulation layer, as polystyrene, hard-foam polyurethane etc., though heat-insulating property is pretty good, its fireproof performance can only reach the B level; What have has then added rock wool, slag silk floss etc., though certain fireproof performance is arranged, this wallboard shrinks at moisture laden air and the easy sedimentation of water volume, causes and the wallboard top layer breaks away from, thereby influence the wallboard use.
Summary of the invention
The technical problem to be solved in the present invention is: Light trabs fire-protection rating in the prior art is low in order to overcome, the technical problem of heat insulation effect difference, a kind of lightweight mixed type laminated wall panel is provided, it brings up to the A1 level with fire-protection rating by the B level, simultaneously possessed good heat-insulating property again, and whole wallboard is slim and graceful.
The technical solution adopted for the present invention to solve the technical problems is: a kind of lightweight mixed type laminated wall panel, comprise metal shell, metal shell is made up of side fascia and inner wall panel, be filled with cement foamed layer in the described metal shell, have outer adhesive linkage between described cement foamed layer and the side fascia, have interior adhesive linkage between cement foamed layer and the inner wall panel.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, and outside plate and the higher metal of inner panel working strength so its strength character is better, can be widely used in temporary building and simple construction simultaneously.
Quick assembling when installing for the realization wallboard, described side fascia one end and inner wall panel one end constitute cambered outwards convex male end mutually, the side fascia other end and the inner wall panel other end constitute the concavity female end that concaves mutually, and described convex male end is that the male and female pairing is pegged graft when plate is connected with plate with the concavity female end.
Intensity for Reinfored wallboard edge, and the sealing of reinforcement connection, the side fascia at described convex male end place has first fold of one section stepped distribution, the tendency of described first fold is for inwardly successively decreasing step by step, the side fascia at described concavity female end place has second fold of one section stepped distribution, the tendency of described second fold is for outwards successively decreasing step by step, and when the male and female pairing was pegged graft between the wallboard, described first fold and second fold docked mutually.
Be filled with the PU material between described cement foamed layer and the concavity female end, the PU material edge sealing that the underrun of concavity female end is filled, the side fascia of described convex male end end face and inner wall panel are filled with the PU material for compressing applying between described cement foamed layer and the convex male end, and PU is polyurethane.
In order to improve wall plate structure intensity, described outer adhesive linkage and interior adhesive linkage are the PUE elastic body, PUE refers to polyurethane elastomer, it is a kind of sprayed on material that multiple macromolecular material is polymerized, have high adhesive strength, and the corrosion of good, wear-resisting anti-skidding, water-fast ageing-resistant, the anti-every medium of pliability.
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, amalgamation immediately and clamping after bonding portion sprayed paint with the PUE elastic body in the working life of defined is used even contact pressure at bonding position assurance is obtained optimum viscosity intensity.
In order to improve the 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, reach best for making the wallboard performance, 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.The performance of wallboard of the present invention 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 etc.
A kind of technology of making lightweight mixed type laminated wall panel comprises following steps:
A, sheet metal is made inside and outside wall board through punching press respectively, with the PUE elastic body that rendering last layer 5um is thick respectively on side fascia and the inner wall panel tow sides, be incubated 4~8 seconds down at 250 ℃, and then the smart thick PUE elastic body of last layer 15um that is coated with, be incubated 4~8 seconds down at 250 ℃, obtain color steel thus;
B, with the 66%-67%(percentage by weight) cement and 30%(percentage by weight) flyash mixes, and then sneaks into 3%-4% polystyrene (percentage by weight), and add blowing agent and obtain cement foamed layer; Blowing agent in this step can be selected physical blowing agent for use, and lower boiling alkane and fluorocarbons are for example arranged.
C, obtain color steel as coating the PUE elastic body on the bonding face again, as the inside and outside adhesive linkage of bonding usefulness with handling among the step a;
D, the cement foamed layer that obtains among the step b is coated between the metal shell that the inside and outside wall board that obtains among the step c constitutes, and makes inside and outside wall board firmly bonding with cement foamed layer by the laminating machine compacting;
After e, process steps d are handled, again the PU material is filled in the metal shell except in other spaces outside the 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 obtain lightweight mixed type laminated wall panel.
As preferably, the amount of polystyrene is the 4%(percentage by weight), in cement foamed layer, add a small amount of polystyrene after, can be so that the weight of cement foamed layer lightens, still performance such as fire prevention does 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 the elastomeric strong adhesion of this kind PUE, can guarantee bonding between inside and outside wall board and the cement foamed layer.
The invention has the beneficial effects as follows that the present invention has replaced the organic plastics warming plate with this incombustible material of ultralight foam cement, reach with its suitable substantially coefficient of thermal conductivity in, solved the nonfireproof shortcoming of metal organic plastics insulation sandwich board; Overcome the metal covering rockwool sandwich board and made moist that back sedimentation contraction, volume reduce, coefficient of thermal conductivity improves shortcoming, most importantly the present invention has cancelled the application of polyurethane insulation coating, directly adopts cement foamed layer to substitute.
