preparation example 1

[0046] Preparation of the first reinforced mesh: first, S glass fiber and aramid fiber are twisted to form the first composite wire, and the chitin fiber is spirally wound around the ultrafine PET / SS composite phase-change energy storage fiber to form the second composite wire. The composite yarn and the second composite yarn are warp yarns, and the first composite yarn and the second composite yarn are weft yarns, which are woven into a first reinforcing mesh with a warp and weft density of 40 threads / 10cm by a flat loom.

preparation example 2

[0048] Preparation of the second reinforced mesh cloth: first, HT carbon fiber and Kevlar fiber are twisted into the third composite thread, and the third composite thread is used as the warp and weft yarn, and the second mesh with a warp and weft density of 40 / 10cm is woven into a flat loom. Reinforced mesh.

preparation example 3

[0050] Preparation of flame-retardant glue: Weigh 1000g water-based polyurethane glue, 85g magnesium dioxide, 89g aluminum dioxide, 22g liquid rare earth flame retardant, 42g nano-silica, 5g multi-walled carbon nanotube MWNT, first mix the water-based polyurethane glue In the reaction kettle, the stirring speed is controlled at 300 rpm, magnesium dioxide, aluminum dioxide and liquid rare earth flame retardant are added in sequence, the stirring speed is controlled at 500 rpm, after stirring for 3 minutes, nano-silica and poly Wall carbon nanotubes MWNT, the stirring speed is increased to 800 rpm, stirred for 2 minutes, the rotational speed is reduced to 300 rpm, stirred for 10 minutes, and a flame-retardant glue is obtained.

Abstract

The invention relates to the technical field of floor preparation, and particularly relates to a flame-retardant floor and a preparation method thereof. The flame-retardant floor comprises a floor main body, wherein the floor main body comprises a beech bottom plate layer, a eucalyptus middle plate layer and a xylosma face plate layer, wherein the beech bottom plate layer, the eucalyptus middle plate layer and the xylosma face plate layer are bonded through flame-retardant glue, and the flame-retardant glue is prepared from the following raw materials in parts by weight: 100 parts of waterborne polyurethane glue and 20-35 parts of a compound non-toxic flame retardant. The product provided by the invention has better flame retardance and reduced formaldehyde emission, the flame retardance of the product can reach a flame-retardant B1(C-s1, t1) level according to GB8624-2012 judgment, and the formaldehyde emission is lower than 0.03mg / m<3>. The preparation method of the product comprises the steps of preparing flame-retardant glue, gluing and laminating the beech bottom plate layer, the eucalyptus middle plate layer and the xylosma face plate layer to obtain a semi-finished floor, performing heat treatment, and naturally cooling to obtain a target finished product.

Description

technical field [0001] The present application relates to the technical field of floor preparation, in particular to a flame-retardant floor and a preparation method thereof. Background technique [0002] Wooden panels are widely used in construction engineering, home decoration, and furniture manufacturing industries. Every year, there are news of property losses caused by fires everywhere, which makes people's awareness of fire prevention gradually improved, and people put forward higher requirements for the fire performance of wood boards. In the selection of wood boards, the use of untreated wood boards should be minimized, and it is best to use flame-resistant and fire-resistant wood boards to prevent the rapid expansion of combustion after the fire source is generated, causing serious fires. Under this industry trend, companies are required to produce floors with better flame retardancy. [0003] Bulletin CN1259379C discloses a waterproof, heat-insulating, and flame-...
