Problems solved by technology

The other is to apply a formaldehyde trap on the surface of the finished floor or fumigate the floor with ammonia water, but the laminate floor treated in this way can only inhibit the release of formaldehyde in a short period of time (up to 1 month), and the floor Cannot be mass-produced on a large scale

Embodiment 1

[0016] When the melamine resin impregnated wear-resistant paper was added the nano formaldehyde removal agent that the percentage by weight is 1%, obtained result is as follows:

[0017]

[0018] The formaldehyde emission of the laminate flooring containing nano-formaldehyde scavenger is lower than that of the laminate floor without nano-formaldehyde scavenger, but it has not yet reached the E0 standard.

Embodiment 2

[0020] When the melamine resin impregnated with wear-resistant paper was added the nano formaldehyde removal agent of 1.5% by weight, the obtained results were as follows:

[0021]

[0022] The laminate flooring containing nano-formaldehyde scavenger has lower formaldehyde emission than the laminate floor without nano-formaldehyde scavenger, but it does not meet the E0 standard.

Embodiment 3

[0024] When the melamine resin impregnated with wear-resistant paper was added the nano formaldehyde remover of 2.5% by weight percentage, the obtained results are as follows:

[0025]

[0026]

[0027] The formaldehyde emission of laminate flooring containing nano-formaldehyde scavenger has partially reached the E0 standard.

Abstract

The invention discloses a laminate flooring which can reach the EO standard. The laminate flooring is formed by hot pressing dipped abrasion resistant paper, decoration paper, balance paper, and medium density fiberboard, wherein the abrasion resistant paper is made by dipping melamine resin added with nano aldehyde removing agent, the weight percent of the nano aldehyde removing agent in the composition is 1% to 20%, and the other is melamine resin. The formaldehyde releasing amount of the laminate flooring is very low and can reach EO standard, which reduces the harm of formaldehyde to the human health and achieves the purpose of environmental protection. The processing technology of the laminate flooring is simple, only need adding prepared nano aldehyde removing agent to the melamine resin for dipping abrasion resistant paper, and then processing the abrasion resistant paper, decoration paper, balance paper, and medium density fiberboard into the laminate flooring by conventional processes.

Description

technical field [0001] The invention relates to a laminate floor, in particular to a laminate floor with low formaldehyde emission, and belongs to the technical field of wood floor processing. Background technique [0002] Now as people pay more and more attention to the concept of environmental protection and health, when people choose laminate flooring, the amount of formaldehyde released from the floor has become the most concerned indicator. The new national standard (GB / T18102-2007) for the first time clarified the new grade E0 of the formaldehyde content of laminate flooring, which is an indicator with a very high technical threshold, that is, the formaldehyde content should be below 0.5mg / L. E0 floor is the most environmentally friendly floor. At present, only Finland, Japan, Germany and other countries in the world have enforced the E0 standard. my country is currently implementing a recommended standard. At present, there are two main processes for the production o...
