Composite blocky floor and preparation method thereof

Abstract

The invention discloses a composite blocky floor and a preparation method thereof. The composite blocky floor is composed of a protective layer, a printing layer (3), a stabilizing layer (4) and a substrate layer (5) which are glued and pressed, wherein the protective layer is a PVC abrasion-resistant layer (2), the stabilizing layer (4) is a mixed extruded product of PVC, calcium carbonate stonepowder, a foaming agent, a lubricant, a modifier and a calcium and zinc composite stabilizer, and the substrate layer (5) is a fiber cement plate or a cement foaming plate or a fiber reinforced calcium silicate plate. The preparation method comprises the steps that firstly, the PVC, the calcium carbonate stone powder, the foaming agent, the lubricant, the modifier and the calcium and zinc composite stabilizer are mixed, and then the obtained mixture is blended and extruded to be formed; then through a hot pressing process, the PVC abrasion-resistant layer (2), the printing layer (3) and the obtained stabilizing layer (4) are composited and then subjected to still standing; and then the obtained mixed layer and the substrate layer (5) are glued and pressed into a whole, and the target product is prepared. The composite blocky floor is high in applicability, good in environmental friendliness and quick and convenient to pave, and is very easily and widely applied to the field of decoration in a commercialized mode.

Description

technical field [0001] The invention relates to a block floor and a preparation method thereof, in particular to a composite block floor and a preparation method thereof. Background technique [0002] At present, the types of floors used in the field of decoration are very rich, including solid wood floors, laminate floors, solid wood composite floors and PVC floors. [0003] Solid wood flooring is also called log flooring. It is directly processed by drying wood. It has natural patterns, comfortable feet, and does not contain formaldehyde and other harmful chemicals. It is also safe to use, but it is not wear-resistant and easy to wear. It loses luster, requires frequent waxing and maintenance, and has poor dimensional stability. If it is used or maintained improperly, it is prone to warping, deformation, and cracks, and the price is relatively high. [0004] Laminate flooring is made by crushing logs, adding glue, preservatives, and additives to log powder, and then press...

Problems solved by technology

Although this floor board has the function of waterproof and sound absorption, there are deficiencies in both the preparation method and the board. First of all, although the cork material used as the sound-absorbing layer in the board can reduce interlayer noise and improve walking comfort, it cannot When there is accumulated water on the ground, it will rot and deteriorate and breed bacteria, thereby destroying the integrity of the floor and affecting its normal use; secondly, the paving of the board needs to set up ridges or lay waterproof membranes on the basis of leveling; finally, prepare The method cannot obtain a practical and environment-friendly floor that can effectively waterproof and pave easily.
