Problems solved by technology

The plant fiber reinforced board is made of chemical raw materials and ingredients, which is easy to age, crack, and has a short life. Ceramic tiles and stones are easy to crack and fall off, and cannot be nailed, drilled, or threaded horizontally or vertically; slag fly ash boards and fly ash gravel cement boards have high water absorption and are easy to crack. The overall structural strength is low, and the impact resistance and bending load resistance are low.
In addition, the above-mentioned non-load-bearing partition wall slats are relatively poor in sound insulation and sound absorption, which makes some noise trouble people's lives

Abstract

The good noise absorption and noise isolation effects are achieved through a three-layer noise insulation structure, at the same time, the overall weight of a wallboard is reduced by one third due to a double-layer hollow structure, and light weight and noise insulation are really achieved; and at the same time, waste like coal ash and plant straws is applied to a wallboard structure through a scientific formula, so that waste is changed into wealth, and the noise insulation effect is improved. In addition, as gypsum has the good noise absorption effect, the gypsum is added to serve as a part of gel material, a composite retarder is adopted in order to make condensation of the gypsum meet the requirement of a production process, the compressive strength and flexural strength of the structure obtained through the production process are greatly improved, the water-resistant performance and degraded recovery performance are greatly enhanced, the high intensity, light weight and noise insulation effects are achieved, and large-batch production can be achieved.

Description

technical field [0001] The invention relates to the field of environment-friendly and energy-saving building materials, in particular to a light-weight sound-insulating non-load-bearing partition wall slat and a production process thereof. Background technique [0002] The use of wall panels can make the construction of walls less labor-intensive, save labor costs, and speed up construction. When used as interior wall panels, there is no need for structural columns, reinforcement belts or ring beams, and doors and windows do not need lintels. They can be used independently without any The auxiliary structure does not require a large amount of masonry mortar; no plastering is required after installation, and the comprehensive construction efficiency of the wall is significantly improved; and the wall panel module is large, light in weight, easy to install and transport, and can be cut and drilled at any position. The board body has high strength, very good flatness, modular i...
