CN201824427U - A composite floor substrate - Google Patents

Abstract

The utility model provides a composite floor substrate, which comprises a substrate, the base plate comprises timber board and cement fiberboard, and this timber board bonds in cement fiberboard surface. The utility model discloses firm characteristic with high density, under the great or chance water soaking condition of temperature variation, its size is almost unchangeable, and good stability is that general pure wooden composite floor can't possess, is applicable to the cold zone and has the ground pavement of "geothermal type" heating installation. The fireproof performance is better, the cement fiber board is adopted as the base board, and then the wood board is pasted, and the overall fireproof performance is better than that of a pure wood composite floor. The cement with rich resources is used as the main raw material of the cement fiberboard to replace a pure wood base plate, so that the use amount of wood can be reduced, and the cement fiberboard has good environmental benefit and low cost.

Description

A composite floor substrate

technical field

The utility model relates to a floor base material, in particular to a composite floor base material composed of wood and cement fiber boards.

Background technique

The composite floor substrates currently on the market can be roughly classified as follows: solid wood substrates, plywood substrates, fiberboard substrates, and particleboard substrates.

The above base materials are all processed and manufactured with wood as raw materials, and are pure wood base materials. These pure wood base materials all have the following deficiencies:

1. It is easily affected by changes in temperature and humidity, resulting in thermal expansion and contraction, resulting in changes in the size of the substrate, especially in coastal and humid air areas, where the bending and warping of the floor is more prominent.

2. Poor fire resistance.

3. The water resistance is poor. After soaking in water, it is easy to deform, mildew and degumming.

4. The demand for wood raw materials is large, which is not conducive to environmental protection and ecological balance.

Utility model content

Aiming at the deficiencies and defects of the prior art above, the purpose of this utility model is to provide a composite floor base material.

The purpose of this utility model is achieved by adopting the following technical solutions:

A compound floor base material comprises a base plate, the base plate is composed of a wood board and a cement fiber board, and the wood board is bonded to the surface of the cement fiber board.

As a preferred technical solution of the present invention, the wood board is two pieces, which are bonded to the end surface and the bottom surface of the cement fiber board respectively.

As a preferred technical solution of the present invention, there are three wood boards and two cement fiber boards, which are respectively superimposed and bonded together.

As a preferred technical solution of the utility model, a panel is provided on the end surface of the wood board.

Compared with the prior art, the utility model has the following advantages:

1. It has the characteristics of high density and solidity. In the case of large temperature changes or soaking in water, its size is almost unchanged, and its good stability is something that ordinary pure wood composite floors cannot possess. It is suitable for cold areas with "geothermal heat" Type" heating floor covering.

2. The fire performance is better. The cement fiber board is used as the substrate, and then the wood board is pasted. Its overall fire performance is better than that of the pure wood composite floor.

3. Using resource-rich cement as the main raw material of cement fiberboard instead of pure wood substrate can reduce the amount of wood used and has better environmental benefits.

4. Low cost.
