Problems solved by technology

[0004] However, the existing lightweight wallboards have low strength and poor fireproof performance. Therefore, most of the current market uses α-type high-strength gypsum to make gypsum boards, or use cement as the base material to prepare GRC composite boards, and Foam composite wall panels cannot further meet the requirements of light weight, fire prevention, and ease of construction.
In addition, in engineering construction, due to the fixed specifications of various boards, additional processing is very easy to cause waste, and cast-in-place large-scale gypsum slurry and cement slurry are extremely difficult to generate strength in a short time, which increases the turnover cost of the formwork

Embodiment 1

[0037] The preparation method of cast-in-place phosphogypsum-based early-strength fireproof composite wallboard comprises the following steps:

[0038] (1) Manufacture and support of calcium silicate board:

[0039] A. According to the experimental wall size of 1500mm×1500mm×120mm, cut out two calcium silicate boards with the same size as the largest wall area of ​​1500mm×1500mm;

[0040] B. Drill holes on two calcium silicate boards, the required hole size is 2mm, and the horizontal and vertical spacing between each hole is 50mm;

[0041] C. Place a β-type phosphorus building plaster block at the corner between the two calcium silicate boards and at the middle of the edge of the calcium silicate board. The size of the block is consistent with the design thickness of the cast-in-place wall, which is 120mm×80mm× 60mm block, brush the adhesive on the contact surface of the block and the calcium silicate board; then, set up scaffolding to clamp and fix the two calcium silicate b...

Abstract

The invention discloses a cast-in-situ ardealite based early strength fireproof composite wallboard and a preparation method thereof, and the cast-in-situ ardealite based early strength fireproof composite wallboard is convenient to construct. The preparation method comprises the following steps of (1), manufacturing and erecting of calcium silicate boards; (2), preparation of a gypsum based light fireproof material; and (3) material pouring and forming. By adoption of the cast-in-situ ardealite based early strength fireproof composite wallboard and the preparation method thereof, formwork erecting and dismantling, circulation work and the cost of a cast-in-situ wall are reduced, the fireproof performance of the composite wallboard is improved, the apparent density of the composite wallboard is decreased, the self weight is decreased, meanwhile, the strength of the composite wallboard is ensured, and the hydrolytic resistance of the gypsum based material is improved; and the cast-in-situ ardealite based early strength fireproof composite wallboard is a novel building material which is low in weight, high in strength, capable of preserving heat and insulating heat, excellent in fireproof performance and easy, convenient and fast to construct, has a certain anti-seismic capacity, and is environmentally friendly and free of poison, and solid waste is utilized in a resourceful mode.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a cast-in-place phosphogypsum-based early-strength fireproof composite wallboard and a preparation method thereof. Background technique [0002] The cast-in-place phosphogypsum-based early-strength fireproof composite wallboard and its preparation method are to use phosphogypsum, a by-product of a phosphate fertilizer plant, to process it, add a certain amount of admixtures and admixtures to make a gypsum-based cementitious material, and then fill it with light Prepared with filling materials. It is a substitute for composite wallboard, GRC composite wallboard, gypsum board, etc. developed in recent years. [0003] The cast-in-place phosphogypsum-based early-strength fireproof composite wallboard and its preparation method are a new, light, high-strength, and environmentally friendly wall material, which can effectively reduce the self-weight of the wall when it is us...
