Long-acting micro-odor aroma-releasing type flame-retardant carbon nanospheres and wood board containing same

Abstract

The invention provides a long-acting micro-odor aroma-releasing flame-retardant carbon nanosphere and a wood board containing the same, the carbon nanosphere is prepared by adopting pepper shells, protein compounds and boron-containing compounds as raw materials for solvothermal reaction, and the carbon nanosphere can release micro odor for a long time. The carbon nanospheres are applied to a wood board to obtain the long-acting micro-odor fragrance-releasing flame-retardant wood board, and the prepared wood board can release micro odor for a long time and also has enhanced mechanical properties and excellent flame retardance.

Description

technical field [0001] The invention relates to the technical field of interior decoration materials and processing, in particular to a long-acting, slightly odor-releasing, flame-retardant carbon nanosphere and a wood board containing the same. Background technique [0002] At present, the wood materials used in home interior decoration mainly include wood-based panels, such as wood floors, wood wall panels, wood furniture, and wood skirting boards, which are remolded with wood or fibers, shavings, veneers, and wood strips. In the process of interior decoration, no matter which material is used, product safety should be one of the important indicators to measure the quality of the product. These include: unpleasant odor and long release cycle, flammable wood panels can easily induce flame spread and lead to major property losses and casualties, and conventional flame retardant treatment greatly reduces the mechanical strength of wood panels and other defects.

AI Technical Summary

Problems solved by technology

At present, the solutions to this kind of problems on the market have complex manufacturing process, high cost, poor practicability and often pungent chemical fragrance. Usually, it has a good fragrance when it is first used, but after several months of use, the good smell gradually fades away. Disappeared, there are defects such as short timeliness

[0005] In addition, as a traditional wooden material, wooden boards are still relatively prominent in their flammability, which brings more troubles to their application places.

At present, some wood panels with flame retardant properties are being produced and sold on the market, but most of them use one or more layers of melamine impregnated paper on the surface, and then a layer of wear-resistant layer containing alumina; The flame retardant is used to impregnate the floor substrate with flame retardant treatment; although these treatments have a certain degree of flame retardant function, they have their own disadvantages

For example, the melamine-impregnated paper veneer mainly adopts the surface flame-retardant method, and the preparation of melamine-impregnated paper requires the use of a large amount of melamine chemical raw materials. At present, affected by international trade, the market price of melamine has been soaring, from 7,000 yuan per ton at the end of 2020. As high as 15,000 to 20,000 yuan / t, it is difficult to return to the sales price in 2020 in a short time

In addition, melamine impregnated paper mainly uses base paper impregnated with melamine formaldehyde resin adhesive, so melamine impregnated paper contains a large amount of free formaldehyde, which is harmful to people's physical and mental health. In order to eliminate the impact of formaldehyde in impregnated paper, it is often necessary to add a large amount of adsorbed formaldehyde or The chemical additives used to degrade formaldehyde lead to problems such as poor surface quality and high cost; liquid flame retardants impregnate the base material mainly by using melamine phosphate, ammonium polyphosphate, ammonium dihydrogen phosphate, diammonium hydrogen phosphate, etc. Phosphorus and nitrogen-containing chemical reagents enter the wood cell cavity, and after drying, the flame-retardant chemical reagents remain inside the wood veneer, and the wood veneer is assembled into plywood and other wooden board products through layer-by-layer compounding

This treatment method adopts the flame retardant of the base material, which has the advantages of good flame retardant effect and low fire hazard spread index. The disadvantage is that the use of such nitrogen and phosphorus flame retardants tends to make the wood veneer brittle, reducing the Therefore, compared with the same type of non-flame-retardant wooden boards, the bending strength of the flame-retardant wooden boards obtained by this kind of flame-retardant technology generally decreases by 30% to 50%, which is very important for the "material saving and consumption reduction" in the wood industry. "Policies and the use of wood-based panel end products, etc. are unfavorable

[0006] Therefore, the existing wooden boards cannot meet people's existing diversified market demand for long-acting micro-odour-releasing functions, and the cost of flame-retardant treatment is high, the mechanical strength of wooden boards is low, and it cannot meet the needs of low production costs, multi-effects in one dose , Use simple application requirements
