Abstract

A light-weight hollow brick is composed of two surface layer and a intermediate layer. Said surface layer is made up of cement, sand, cinder and early-strengthening agent. Said intermediate layer is made up of cement, sand, foam plastic block, glass fibres and early-strengthening agent. It is made up through spreading surface mortar, putting the cores at intervals, spreading intermediate layer mortar, and spreading surface mortar. Its advantages are light weight, low cost, high insulating effect, and high performance.

Description

Light-weight hollow-brick and preparation method thereof
Technical field the present invention relates to constructional materials that a kind of constructional materials, particularly interior wall use and preparation method thereof.
Background technology is along with the development of construction business; people have invented some new constructional materialss again, as disclose on the Gazette of Patent for Invention on April 1st, 1992 a kind of (Light trabs and preparation method thereof) (application number 91108526.2) it to the effect that: Light trabs is made of topping, glass layer and intermediate layer.Other material weight proportioning that constitutes wallboard is: cement 20-25%, perlite 20-25%, gypsum 2-3%, alumina 2-3%, refractory material 5-8%, water 30-35%, earlier lysed gypsum of cement, perlite, refractory material and water and alumina are put into mixer by weight ratio during making, once add and be poured into mould after water stirs, and the moulding of vibrating, its weak point is that matter is heavy, heat-insulating property is not good enough, and hardening time is long, and occupied ground is big.
The used raw material of summary of the invention the present invention has: cement, sand, slag, foam-plastic blocks, glass fiber, mortar special glue and glass fabric and early strength admixture.Wherein cement is 500 #Above portland cement; Sand is the building sand that sieves; Slag is to pulverize through mill, and can cross the particle of 5 * 5mm grid; Foam-plastic blocks is the rigid foam particle that specification approximates the soya bean size; The mortar special glue is the cementing agent of bonding cement and foamed plastics, and it is netted that glass fabric is; Early strength admixture (or claiming waterproof agent) is the additive that acceleration cement and other raw material are solidified togather.
The structure of product of the present invention is: the intermediate layer that accompanies light hollow between two panels.Therefore panel is different with the composition in intermediate layer.Wherein the used raw material of panel has: cement, sand, slag, water and early strength admixture.Following part by weight relation is arranged: cement: sand: slag: water=1: 2.5: 0.5: an amount of between them.The mixture solidified time of above-mentioned raw materials shortens if desired, can in raw material, add early strength admixture, itself and cement have following part by weight relation: cement: early strength admixture=1000: 0-1.2, the used raw material in intermediate layer has: cement, sand, foam-plastic blocks, glass fiber, mortar special glue, water and early strength admixture.Following part by weight relation is arranged: 1. cement between them: sand: foam-plastic blocks: glass fiber: water=50: 10: 1-1.2: 2-3: an amount of; 2. (cement+sand+foam-plastic blocks+glass fiber): mortar special glue=500: 2-3; 3. cement: early strength admixture=1000: 0-1.2.
The preparation method of product of the present invention is as follows:
1, make panel, raw panels is modulated into mortar for building with mixer, then with its Shop in one plane, thickness is 20 millimeters, preferably adopts the method for vibration to remove the bubble in the mortar and make it density equalization everywhere.Be preferably in and lay one deck glass fabric on the above-mentioned panel, be used to increase the intensity of this hollow brick.
2, make the intermediate layer, on above-mentioned panel (or glass fabric), be provided with in parallel and the fuse of certain interval is arranged with it.Lay the intermediate layer mortar on above-mentioned panel or glass fabric, its thickness is the 80-120 millimeter, and the bubble that preferably adopts method for oscillating to remove in the mortar makes it density equalization everywhere.Preferably on above-mentioned intermediate layer, lay one deck glass fabric.
3, make another panel, layer overlay thickness is 20 millimeters panel mortar on above-mentioned intermediate layer or glass fabric.What obtain after above-mentioned each layer curing is light cement slab, and the product that obtains after cutting is light-weight hollow-brick.
The present invention has following advantage compared to existing technology:
1, compressive strength is higher than the GB15229-94 standard, and other index also all is higher than national standard, can increase usable floor area indirectly.
2, high insulating effect can be saved heat cost.
3,, can reduce the degree of depth of building foundation from heavy and light.
4, price is low, is lower than the price of common brick.
5, manufacture craft is simple, hardening time is fast, occupied ground is few.
Description of drawings
Fig. 1 is the schematic cross-section of product of the present invention.
The specific embodiment
Example 1 is added to 100 kilograms of 500# portland cements, 250 kilograms of sands, 50 kilograms of slags and an amount of water in the concrete mixer, stirs and makes it even mixing, and what obtain is the panel mortar.This mortar is had in the plane of template around placing, and the vibration mortar makes density equalization everywhere, and the mortar that again thickness is surpassed 20mm is wiped off, and what obtain is this hollow brick panel 1.On above-mentioned panel, lay one deck glass fabric 2 corresponding with its planar dimension.On above-mentioned glass fabric, be provided with in parallel and the tubular core of certain interval is arranged with it.On above-mentioned glass fabric, lay the intermediate layer mortar, this mortar is after earlier 0.512 kilogram of stupid plate of smart board (EPS X PS) mortar special glue (the strong sunshine Concrete admixtures manufacturing company in Shenyang product) and water being mixed, again with other raw material promptly 100 kilograms of 500# portland cements, 20 kilograms of sands, 2 kilograms of rigid foam pieces, 6 kilograms of glass fiber be added to simultaneously in the concrete mixer, stirring, what obtain is the intermediate layer mortar.The vibration mortar is removed bubble and is made density equalization everywhere, and the mortar that thickness is surpassed 80mm is wiped off, and what obtain is this hollow brick intermediate layer 3.On above-mentioned intermediate layer, lay one deck planar dimension glass fabric 4 corresponding with it.On this glass fabric, repave last layer panel mortar, will wipe off above the mortar of 20mm after the vibration, obtain another panel 5 of this hollow brick.After above-mentioned each layer solidified, fuse was taken out in the demoulding, obtains light cement slab.With above-mentioned sheet material stripping and slicing, the product that obtains is light-weight hollow-brick as required.
Example 2 repeats the operation of example 1, and wherein the raw material of panel mortar also includes 0.12 kilogram of early strength admixture (building materials market product sold) it gives elder generation and mixes with the raw material water, is added in the mixer then.In the raw material of intermediate layer mortar, foamed plastics is that 2.4 kilograms, glass fiber are that 4 kilograms, mortar special glue are 0.758 kilogram.Also include 0.12 kilogram of early strength admixture in addition, together be added in the concrete mixer with water after it also needs to give elder generation and water mixes again, the thickness in intermediate layer is 120mm.
The said goods is through checking every technical indicator result as follows:
