Embodiment 1

[0067] An environmentally friendly flame-retardant and antibacterial fiberboard for laminate flooring, the preparation process of which comprises the following steps:

[0068] The first step, wood fiber is dried to moisture content 10wt%;

[0069] In the second step, the dried wood fiber is put into a high-speed mixer and stirred at 1500 rpm for thinning for 1 minute to obtain thinned wood fiber;

[0070] The third step is to mix the thinned wood fiber and 3% of its weight of nano-bentonite evenly, pave it into the mold, pre-press it through a pre-press, and cut off the burrs to obtain a slab;

[0071] The fourth step is to heat-press the slab using a hot-press machine, with a hot-pressing pressure of 4 MPa and a temperature of 170°C. After hot-pressing for 4 minutes, stop the hot-pressing;

[0072] The fifth step is to place the hot-pressed board in an indoor environment of 20° C. for 15 days to obtain the environmentally friendly flame-retardant and antibacterial fiber boar...

Abstract

The invention discloses an environment-friendly flame-retardant antibacterial fiberboard for a reinforced wood floor. The producing process of the environment-friendly flame-retardant antibacterial fiberboard for the reinforced wood floor comprises the steps of wood fiber drying, thinning, prepressing, hot pressing and balanced placing. By means of the environment-friendly flame-retardant antibacterial fiberboard for the reinforced wood floor, the effective combustion heat and mass loss rate of the fiberboard are reduced, the quantity of generated combustible volatile matters is reduced, and the flame retardant performance of the fiberboard is obviously improved; and meanwhile, different from the surface bacteriostasis of other fiberboards, bacteriostatic components are added into the fiberboard to effectively prevent and inhibit harmful microorganisms, ensure the mechanical properties of the fiberboard, and endow the fiberboard with excellent bacteriostasis and mildew resistance performance.

Description

technical field [0001] The invention relates to the field of material technology, in particular to an environmentally friendly flame-retardant and antibacterial fiberboard for laminate flooring. Background technique [0002] The laminate flooring currently on the market is made of high-density fiberboards, which are made of wood fibers or straw fibers and adhesives. Adhesives are mainly urea-formaldehyde resins, phenolic resins, etc., and auxiliary materials are generally insect repellents of chemically synthesized materials. The high-density board made of this adhesive and auxiliary materials or the further produced laminate flooring will release harmful substances such as formaldehyde, which has certain toxicity and peculiar smell and is easy to deform. Once it is damp, it is easy to mildew and breed Bacteria, pests, etc. [0003] The invention of application number 201510756424.5 discloses an environmentally friendly flame-retardant and antibacterial laminate flooring a...
