Embodiment Construction

[0004] Take 100 parts by weight of light-burned magnesia (wherein the content of magnesia is 70-90%), 100-140 parts by weight of filler sawdust (wheat straw, rice straw, sorghum, corn and other crop stalks can be crushed) 100-140 parts by weight, fly ash 20 to 60 parts by weight, some hemp knives and the improving agent are calcium superphosphate and calcium lignosulfonate in a ratio of 3:1, and the proportion is 3 to 7 parts by weight, and then poured into a mixer for dry mixing; then add an aqueous solution of magnesium chloride ( Specific gravity is 1.16-1.25) 160-240 parts for stirring, the stirred slurry is sent to the extrusion molding machine for extrusion molding, natural curing at room temperature for 2-3 days, after cutting according to the required size, the board is lifted, inspected and put into storage Palletizing, and then natural curing for 20-25 days to make magnesium cement lightweight wall panels.

Abstract

The invention discloses a lightweight cement wall plate manufacturing method, and belongs to the technical field of building material prefabrication molding. In the prior art, the currently used cement wall plate has disadvantages of insufficient strength, insufficient toughness, easy crack generation, and high price. The technical scheme of the invention comprises: carrying out metering matching on light burned magnesium oxide, fly ash, sawdust, hemp fiber and a modifier, pouring the obtained mixture into a stirrer, carrying out dry mixing, adding a magnesium chloride aqueous solution in a metered manner, stirring, conveying the stirred slurry into an extrusion molding machine, and carrying out extrusion molding to prepare the magnesium cement lightweight wall plate. According to the present invention, the manufacturing process is simple, and the prepared lightweight wall plate has advantages of good performance and low price.

Description

technical field [0001] The invention relates to the technical field of building material prefabrication, more specifically a method for manufacturing magnesium cement (magnesium oxychloride cement) lightweight wall boards. Background technique [0002] The currently used cement wallboard needs to be foamed in order to achieve light weight, which results in poor strength and toughness, prone to wall cracks, and the high price has affected its popularization. Contents of the invention [0003] For overcoming above-mentioned shortcoming, the purpose of the present invention is to invent a kind of cement light wall board manufacture method. Its technical scheme is as follows: first, lightly burned magnesia, fly ash, sawdust, hemp knife and modifier are metered and batched, and then poured into a mixer for dry mixing; The slurry is sent to an extrusion molding machine for extrusion molding to make magnesium cement lightweight wall panels. Their proportions are: 100 parts by w...
