Problems solved by technology

[0004] However, the existing lightweight blocks have low strength and poor fireproof performance. Therefore, most of them on the market are made of α-type high-strength gypsum. The wall cannot further meet the requirements of light weight, high strength and multi-function, and phosphogypsum has great regional characteristics, and the applicable formula is different in each place. Therefore, in view of the particularity of Yunnan phosphogypsum, a light-weight phosphogypsum base Preparation method of fire-proof and non-burning block

Abstract

The invention relates to a preparing method of a light ardealite-based fireproof non-burned building block. The method includes steps of (1) raw material preparation, (2) mold injection and molding, and (3) demolding and shaping. The invention also relates to the light ardealite-based fireproof non-burned building block prepared by the method. The method improves compressive strength and the softening coefficient of gypsum building blocks, and greatly reduces the apparent density of the gypsum building blocks. A production process is simple and environmentally friendly. The non-burned building block can be adopted as a wall body separately. The non-burned building block is a novel building material which is light in weight, high in strength, heat-insulating, excellent in fireproof performance and capable of being nailed, sawed and shaved, which has certain earthquake resistant capacity and a low cost, and which is environmentally friendly, low in carbon and convenient to construct.

Description

technical field [0001] The invention relates to a preparation method of a fireproof block, in particular to a preparation method of a phosphogypsum-based fireproof and non-burning block, and also relates to a fireproof block obtained by the preparation method, which belongs to the field of building materials. Background technique [0002] Light-weight phosphogypsum-based fire-proof and non-burning blocks are prepared by using phosphogypsum, a by-product of the phosphate fertilizer plant, after treatment, adding a certain amount of admixtures and external admixtures to make gypsum-based cementitious materials, and then filling them with light fillers. . It is a substitute for expanded perlite blocks, foam bricks, and aerated concrete blocks developed in recent years. [0003] Light phosphogypsum-based fire-proof and non-burning block is a new type of wall material with light weight, high strength and environmental protection. It is used in the construction of non-load-bearin...
