Problems solved by technology

However, there are various deficiencies and defects in these floors: marble floors often contain radioactive substances, and long-term contact will have adverse effects on the body; laminated wood floors are composed of high-density fiber substrates and printed paper surfaces, and their disadvantages are: It is afraid of water and moisture, and is prone to produce harmful substances such as formaldehyde; multi-layer solid wood composite flooring uses lath inlays or whole boards and multi-layer plywood as the base material. VOC is easy to exceed the standard; the quality of solid wood flooring is high but the price is high, and a large amount of logs are consumed in the manufacturing process, which is not friendly to the environment and is prone to noise, which is not good for human health. Therefore, generally laid wooden floors have adverse effects on the human body and the environment. , does not conform to the concept of green environmental protection in a harmonious society

preparation example Construction

[0042] The present invention also provides a preparation method for the flax composite floor described in the above technical solution, comprising the following steps:

[0043] (1) mixing flax stalk scraps, water-based polyurethane, linseed oil and rosin to obtain a flax stalk composite raw material;

[0044] (2) calcium carbonate, water-based polyurethane, linseed oil and rosin are mixed to obtain calcium carbonate composite raw material;

[0045] (3) The jute coarse cloth, the calcium carbonate composite raw material obtained in the step (2) and the flax stalk composite raw material obtained in the step (1) are sequentially stacked and molded to obtain a flax composite floor;

[0046] The steps (1) and (2) are not in chronological order.

[0047] In the present invention, the dosage of each component in the preparation method is consistent with the dosage of the components in the technical solution of the above-mentioned linen composite floor, and will not be repeated here....

Embodiment 1

[0057] The flax stalk scraps were dried at 80°C for 24h, and the calcium carbonate was dried at 80°C for 24h. Mix 8g of dried flax stalk scraps with 10g of water-based polyurethane, 2g of linseed oil and 2g of rosin at a speed of 200r / min for 10min to obtain a flax stalk composite material; 20g of dried calcium carbonate and 6g of water-based Polyurethane, 2 g of linseed oil and 2 g of rosin were stirred and mixed for 10 min at a speed of 200 r / min to obtain a calcium carbonate composite raw material. Such as figure 2 The relative relationship between the material shown and the flat vulcanizing machine, the area is 10cm 2 The jute coarse cloth (the size of the jute coarse cloth mainly depends on the size of the flat vulcanizing machine mold, that is, the size of the jute coarse cloth should adapt to the length and width of the mold), the calcium carbonate composite raw material and the flax stalk composite raw material are laid sequentially under the flat vulcanizing machine...

Embodiment 2

[0060] The flax stalk scraps were dried at 80°C for 24h, and the calcium carbonate was dried at 80°C for 24h. Mix 7g of dried flax stalk scraps with 12g of water-based polyurethane, 2g of linseed oil and 2g of rosin at a speed of 200r / min for 10min to obtain a flax stalk composite material; mix 18g of dried calcium carbonate and 10g of water-based Polyurethane, 2 g of linseed oil and 2 g of rosin were stirred and mixed for 10 min at a speed of 200 r / min to obtain a calcium carbonate composite raw material. Set the area to 10cm 2 The jute coarse cloth, calcium carbonate composite raw material and flax stalk composite raw material are sequentially laid in the rectangular concave cavity under the mold of the flat vulcanizer, and the surface of the concave cavity composite raw material is rolled by a pressure roller to fill the cavity with the raw material. cavity, and make the surface of the raw material flat, align the upper and lower molds of the mold and put them into the fla...

Abstract

The invention belongs to the technical field of floor decoration materials, and particularly relates to a flax composite floor. The flax composite floor comprises a flax straw dust composite layer, acalcium carbonate composite layer and a hessian layer which are sequentially bonded; the flax straw dust composite layer comprises flax straw dust, waterborne polyurethane, linseed oil and rosin; thecalcium carbonate composite layer comprises calcium carbonate, the waterborne polyurethane, the linseed oil and the rosin. The flax composite floor has the advantages that component materials in the floor does not volatilize pollutants, the purposes of green and environmental friendliness are really achieved, composite material structures are allowed to be optimized by three layers of composite structures to be conformed to actual using demands, the content of all raw materials is optimized, so that the composite floor has higher breaking strength and lower surface permeability, therefore a provided product does not volatilize pollutants, and green and environmental friendliness of the flax composite floor are achieved.

Description

technical field [0001] The invention belongs to the technical field of floor decoration materials, in particular to a linen composite floor and a preparation method thereof. Background technique [0002] Flooring is the surface layer of the ground or floor of a building, made of wood or other materials. There are many classifications of floors, classified by structure: solid wood flooring, laminated wood flooring, three-layer solid wood composite flooring, bamboo wood flooring, anti-corrosion flooring, cork flooring and the most popular multi-layer solid wood composite flooring. At present, there are many kinds of floors with different performances, including solid wood floors and marble floors. However, there are various deficiencies and defects in these floors: marble floors often contain radioactive substances, and long-term contact will have adverse effects on the body; laminated wood floors are composed of high-density fiber substrates and printed paper surfaces, and t...
