A modified fiber-reinforced foamed cement composite floor and its preparation method

Abstract

The invention discloses a modified fibre enhanced foaming cement composite floor. The modified fibre enhanced foaming cement composite floor comprises a wearing layer, a decorative layer, an insulating layer and an interface connecting layer. The decorative layer is arranged below the wearing layer, the insulating layer is arranged below the decorative layer, and the interface connecting layer isarranged below the insulating layer. The preparation method comprises the steps of preparing modified fibre, making an insulation plate, making the insulating layer, and post processing of the insulating layer. The modified fibre enhanced foaming cement composite floor has the advantages of high compressive strength, sound insulation, low thermal conductivity, steady chemical property, environmental protection, small deformation and the like. The construction only needs to use special adhesive mortar to paste directly in the base layer, the working procedure is few, the construction is quick,and the efficiency is high. Product tight seam splices, maintenance and replacement are convenient.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a modified fiber-reinforced foamed cement composite floor and a preparation method thereof. Background technique [0002] Laminate flooring is one type of flooring. However, the composite floor is artificially changed the natural structure of the floor material to achieve a floor whose physical properties meet the expected requirements. Composite flooring often refers to laminate flooring and solid wood composite flooring in the market. [0003] Foamed cement is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, and evenly mix the foam with the cement slurry, and then go through the pumping system of the foaming machine for cast-in-place construction or mold molding. A new type of lightweight thermal insulation material with a large number of closed pores formed by natural conservation. It belongs to the bubble-like therm...

Problems solved by technology

[0004] With the improvement of building energy-saving requirements for building thermal performance and green building promotion, in addition to the comprehensive promotion and use of external wall insulation, ground insulation and sound insulation have also gradually received attention. Most of the existing technologies are based on reinforced composite wood flooring. However, the reinforced composite wood floor is covered in the later stage of home decoration; and because the cost of reinforced composite wood floor is relatively high, nowadays, there is an urgent need for a kind of light weight, high strength, which can be used as a ground cushion and has a Pre-floor with excellent thermal insulation and sound insulation performance

[0005] At present, cast-in-place foam concrete, benzene board, and full-light concrete are mostly used for ground insulation. However, cast-in-place foam concrete is hollow and severely cracked due to the typical sandwich structure of aggregate, clean slurry, and foam due to the layering and segregation of slurry.

The thermal conductivity of benzene board is low, and the heat insulation effect is good, but there are also disadvantages such as easy to be compressed and deformed, fatigue strength deformation, and thermal conductivity increase.

However, the quality of all-light concrete is difficult to monitor due to the variation, instability, and multi-component properties of light aggregates.
