preparation example Construction

[0015] The embodiment of the present invention provides a method for preparing a multifunctional formaldehyde-free floor, comprising:

[0016] S1. Preparation of fiber substrate

[0017] The fiber substrate in the embodiment of the present application is prepared by using logs as raw materials, and its preparation method can refer to the existing process, which is not limited here, that is, it is not limited to the specific process listed in the embodiment of the present invention. In some embodiments, commercially available fiber substrates may also be used directly without preparation of the fiber substrates.

[0018] The preparation process of the fiber substrate includes: applying formaldehyde-free glue to the fiber raw material, drying to a water content of 5-8%, and then performing pre-pressing and hot-pressing. Formaldehyde-free glue can use isocyanate formaldehyde-free glue and / or lignin formaldehyde-free glue, the application amount of isocyanate formaldehyde-free gl...

Embodiment 1

[0035] This embodiment provides a method for preparing a multifunctional formaldehyde-free floor, including:

[0036] (1) Prepare the base material: peel the logs, peel them with a flaker, wash them with water, and then place them in a power roller screen for grading and screening, then perform high-temperature cooking and grinding with a hot mill to obtain fiber raw materials for strengthening the base material;

[0037] (2) Sizing: apply 25kg / m to the fiber raw material 3 isocyanate formaldehyde-free glue and 60kg / m 3 lignin-free formaldehyde-free glue.

[0038] (3) Drying: Dry the fiber raw material after glue application, and control its moisture content at about 5%.

[0039] (4) Slab pre-pressing and hot pressing: After the above-mentioned wood fiber is screened by a cyclone separator, it is formed into a uniform thickness and quality by a vacuum paving machine; then a continuous roller press is used to pre-press the paved slab After the slab is preliminarily formed, i...

Embodiment 2

[0049] This embodiment provides a method for preparing a multifunctional formaldehyde-free floor, including:

[0050] (1) Prepare the base material: peel the logs, peel them with a flaker, wash them with water, and then place them in a power roller screen for grading and screening, then perform high-temperature cooking and grinding with a hot mill to obtain fiber raw materials for strengthening the base material;

[0051] (2) Sizing: apply 30kg / m to the fiber raw material 3 isocyanate formaldehyde-free glue and 40kg / m 3 lignin-free formaldehyde-free glue.

[0052] (3) Drying: Dry the fiber raw material after gluing, and control its moisture content at about 8%.

[0053] (4) Slab pre-pressing and hot pressing: After the above-mentioned wood fiber is screened by a cyclone separator, it is formed into a uniform thickness and quality by a vacuum paving machine; then a continuous roller press is used to pre-press the paved slab After the slab is preliminarily formed, it enters a...

Abstract

The invention discloses a multifunctional formaldehyde-free floor and a preparation method thereof, and relates to the technical field of floors. The preparation method of the multifunctional formaldehyde-free floor comprises the steps that impregnated wear-resistant paper, impregnated decorative paper, a fiber base plate and impregnated balance paper which are arranged in sequence are subjected to compression molding, wherein the impregnated balance paper, the impregnated decorative paper and the impregnated wear-resistant paper are obtained after balance paper, decorative paper and wear-resistant paper are impregnated with glue; one or more of a preservative, a mildew preventive and negative oxygen ion powder are added into the glue for impregnating the wear-resistant paper. The floor is endowed with corrosion resistance and mildew resistance through the preservative and the mildew preventive, negative oxygen ions are released through the negative oxygen ion powder, the air quality of the environment is improved, and the floor with one or more effects of the corrosion resistance, the mildew resistance or peculiar smell removal can be prepared.

Description

technical field [0001] The invention relates to the field of floor technology, and in particular to a multifunctional formaldehyde-free floor and a preparation method thereof. Background technique [0002] Flooring is an important building material with many classifications, such as solid wood flooring, laminated wood flooring, bamboo flooring, anti-corrosion flooring, cork flooring and the most popular multi-layer solid wood composite flooring. During the use of the floor, mildew and corrosion may occur, and with the improvement of the quality of life, more requirements are put forward for the versatility of the floor. [0003] The existing floor mainly has the following problems: (1) the anti-corrosion and anti-mildew effect is not good, and it is very easy to mildew or rot; (2) the floor will release harmful gases such as formaldehyde and emit peculiar smell. Contents of the invention [0004] The object of the present invention is to provide a multi-functional formald...
