Fiber-reinforced composite material cement board and preparation method thereof

Abstract

The invention discloses a method for preparing a fiber composite material concrete board, which comprises the following steps: laying a first layer of slurry in a mould; laying a first layer of glass fiber grid cloth on the laid first layer of the slurry; laying a second layer of slurry on the laid first layer of the glass grid cloth; laying a second layer of glass fiber grid cloth on the laid second layer of the slurry; laying a third layer of slurry on the laid second layer of the glass fiber grid cloth; vibrating the mould by a vibration device; putting the mould into a steam autoclave; and performing autoclave leaving, demoulding, airing and final treatment to form the concrete board made of the fiber composite material. The invention also discloses a concrete board made of a fiber composite material. The method has the advantages of simple manufacturing process, little capital and equipment input and low cost; and the concrete board made of the fiber composite material has the advantages of low water absorbing rate, high strength, good toughness, high durability, and the like.

Description

technical field

[0001] The invention relates to a manufacturing technology of a fiber-reinforced composite material cement board, in particular to a fiber-reinforced composite material cement board and a preparation method thereof. Background technique

[0002] Over the past 20 years, there are roughly 7 categories of new fiber-reinforced cement-based composite materials developed and developed at home and abroad (mainly abroad), namely: 1. Metal fiber-reinforced cement-based composite materials; 2. Glass fiber-reinforced cement-based composite materials; 3. Synthetic fiber-reinforced cement-based composite materials; 4. Natural organic fiber-reinforced cement-based composite materials; 5. Carbon fiber-reinforced cement-based composite materials; 6. Hybrid fiber-reinforced cement-based composite materials; 7. High-performance fiber-reinforced cement-based composite materials . The process of making boards from the above materials is complicated, and the investment in equipm...
