High-strength waterproof composite light partition board and preparation method thereof

Abstract

The invention discloses a high-strength waterproof composite light partition board. The high-strength waterproof composite light partition board comprises the following materials by weight: 95-70 Kg of high-temperature gypsum, 5-30 Kg of a modified material, 1-2 Kg of a water reducing agent, 30-40 Kg of water, 0.1-0.3 Kg of fibers and 0.1-0.3 Kg of a retarder. The high-temperature gypsum is anhydrous gypsum prepared by heating dihydrate gypsum at high temperature to lose water; the modified material comprises cement, ground slag powder, silicon powder and ground steel slag; the water reducing agent is a water reducing agent for concrete; the fibers comprise artificial fibers and natural fibers; the retarder comprises citric acid, borax and melamine; and the water meets the standard requirements of concrete mixing water. With the high-strength waterproof composite light partition board and the preparation method thereof of the invention adopted, the defects of low strength, poor water resistance, small single nail hanging force and poor single nail bond stress of gypsum composite light partition boards can be solved; the consumption ways of industrial byproduct gypsum are increased. The high-strength waterproof composite light partition board and the preparation method play a positive role in protecting the natural environment, natural resources, recycling hazardous wastes, reducing the livelihood cost and the like and promoting absorption.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a high-strength, water-resistant composite lightweight partition board and a preparation method thereof. Background technique [0002] my country has abundant gypsum mineral resources and a large amount of industrial by-product gypsum, which provides abundant resources for the preparation and production of gypsum. Because gypsum has the characteristics of fast setting time, good plasticity, light weight, good mold filling, recyclable utilization, and micro-expansion, gypsum, as a traditional building material, has extremely high utilization value. At present, it has been widely used in building materials, medicine and other industries. Due to the shortcomings of hemihydrate gypsum produced by traditional technology, such as high water absorption, poor water resistance, low softening coefficient, poor wear resistance, and poor frost resistance, gypsum build...

AI Technical Summary

Problems solved by technology

Due to the shortcomings of hemihydrate gypsum produced by traditional technology, such as high water absorption, poor water resistance, low softening coefficient, poor wear resistance, and poor frost resistance, gypsum building materials and products are mainly used in indoor dry environments

[0003] According to the known literature records, due to the problems of gypsum water resistance and wear resistance of the current partition boards, the application of gypsum lightweight partition boards in outdoor and humid environments is very small, which limits the use of gypsum lightweight partition walls.
