Problems solved by technology

However, most of the lightweight wall materials currently on the market are wood boards and MDF boards with poor fire resistance, gypsum boards with poor water resistance and low strength, or heavy overall cement walls, and most of these boards are only used for Indoor partition walls, when used for exterior walls, will soon have unsafe defects such as softening and cracks after being exposed to sunlight and rainwater

Abstract

The invention discloses a fiber cement composite plate production process. According to the invention, a well stirred base material is paved through template delivery; a first layer of glass fiber cloth is paved; a middle material is paved; a second layer of glass fiber cloth is paved; the glass fiber cloth is cut, and first constant-temperature maintenance is carried out; de-molding is carried out after 20-30h of maintenance; the plate material is wetted by spraying water, and secondary constant-temperature maintenance is carried out; and after 3-10 days, edge sawing and trimming processes are carried out, such that a finished product is obtained. Compared with prior art, with the fiber cement composite plate production process, the produced fiber cement composite plate has high fireproof performance, high waterproof performance, good safety, and no toxicity. The plate can be directly used in interior or exterior wall decoration. The plate is a durable novel construction plate material.

Description

technical field [0001] The invention relates to the field of building boards, in particular to a production process of fiber cement composite boards. Background technique [0002] Driven by the national environmental protection and energy-saving policy, it will be an inevitable trend for clay bricks to withdraw from the urban construction market and will be replaced by new lightweight wall materials. Therefore, the gap for new lightweight wall materials will become larger and larger. New lightweight wall materials with good performance will enter the construction market at a relatively fast speed, especially in the construction of high-rise and super high-rise buildings. The demand market potential for high-quality board products is huge. However, most of the lightweight wall materials currently on the market are wood boards and MDF boards with poor fire resistance, gypsum boards with poor water resistance and low strength, or heavy overall cement walls, and most of these b...
