Wood floor taking inorganic material as base material and preparation method thereof

Abstract

The invention relates to a wood floor taking an inorganic material as a base material, which comprises a surface layer and an inorganic base material plate, and the surface layer is compounded on thesurface of the inorganic base material plate; the surface layer is a decorative film with wood patterns or a veneer material; the inorganic base material plate is integrally formed by cement paste ina pouring mode. Wherein the cement paste comprises the following components in percentage by mass: 20-60% of cement, 30-70% of quartz sand, 0.1-10% of microbeads, 0.01-2% of a water reducing agent, 0.01-2% of lithium carbonate, 0.01-2% of sodium gluconate, 0.01-2% of glass fibers and 0.1-6% of a low-temperature water-based emulsion; the above components are mixed with water to obtain the cement paste, the water-binder ratio of the cement paste is 0.25-0.5, and the cement-sand ratio of the cement paste is 0.25-0.7. The inorganic base material plate adopts an innovative cement paste formula, canprovide higher breaking strength and compressive strength under the condition of extremely thin thickness after being cured, can reduce the weight of the floor, and has the advantages of durability,fire resistance, flame retardance, no VOCs and the like. During preparation, the dosage of sodium gluconate, lithium carbonate, microspheres, the water reducing agent and the like is regulated and controlled, so that the early strength of concrete is enhanced, the setting time is shortened, the later strength is not lost, demolding can be performed only after curing is performed for 2 hours, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of interior decoration boards, in particular to a wooden floor using inorganic materials as a base material and a preparation method thereof. Background technique [0002] Wooden flooring has the advantages of beautiful texture and low heat transfer coefficient, but wooden flooring requires a lot of wood. Especially in the past 10 years, my country's urbanization rate is very fast, the demand for indoor flooring is increasing day by day, the supply of wood is in short supply, and a large number of felling trees can easily cause vegetation damage. In order to save log wood, wood floors made of wood chips or wood powder with adhesives to press boards have appeared on the market. A large amount of glue is used in the production process of this kind of wooden floor, and there is a problem of excessive formaldehyde or other VOCs, which brings huge hidden dangers to the indoor environment and people's health. In...

A large amount of glue is used in the production process of this kind of wooden floor, which has the problem of excessive formaldehyde or other VOCs, which brings huge hidden dangers to the indoor environment and people's health

In addition, wooden floors are flammable and not flame retardant. Some laminated boards will release a large amount of toxic smoke when burning, which will threaten life when there is a sudden event such as fire.

On the other hand, the strength of the wooden floor is not enough, and it needs to be strictly leveled when paving, otherwise it is easy to warp and break, and the durability time is short, especially in some places where the climate is humid and rainy, the internal structure of the wood will change, causing swelling and Shrinkage further exacerbates wood warping, deformation and cracking
