[0037] Preparation method of impregnated reinforced composite floor

[0038] The preparation method of impregnated reinforced composite floor of the present invention, described floor is made by the method comprising the following steps:

[0039] Provide one or more layers of veneers, and an impregnating liquid, wherein the impregnating liquid comprises 100 parts by weight of polymer monomers (such as acrylic monomers or styrene monomers, the acrylic monomers include methyl methacrylate , vinyl acetate or a combination thereof, the styrene monomers include substituted or unsubstituted styrene monomers), 0-0.5 parts by weight of initiator, 0-10 parts by weight of oil-soluble dyes, 0-10 parts by weight Parts of floor additives;

[0040] providing a closed space, in which the impregnating liquid is immersed into the one or more layers of veneers, and the polymerization of the polymer monomer in the impregnating liquid is initiated to obtain an impregnated surface plate;

[0041...

Embodiment 1～3

[0105] Raw material of the present invention:

[0106] Impregnation solution: Methyl methacrylate and initiator azobisisobutyronitrile are mixed in a weight ratio of 100:0.15, and 5% by weight of oil-soluble dyes are added (proportionately prepared according to red, yellow and black, methacrylic acid Methyl ester 100: oily red 1.84: oily yellow 0.86: solvent black 0.3).

[0107] Veneer #1: (manufacturer: Shanghai Weijia, model: 1240×106×2.1mm, material: oak wood)

[0108] Veneer #2: (manufacturer: Shanghai Weijia, model: 1240×106×2.1mm, material: colored wood)

[0109] Veneer #3: (Manufacturer: Shanghai Weijia, model: 1240×106×2.1mm, material: maple.)

[0110] Substrate: (manufacturer: Shanghai Weijia, model: 1240×1240×8.5mm, material: poplar.)

[0111] (1) Put the veneer #1 into the impregnation curing tank at intervals, first vacuum for 10-30 minutes to remove the moisture and air in the veneer, and then suck the impregnation solution to ensure that all the veneers are su...

Embodiment 4

[0125] The floor of embodiment 4 is according to the method of embodiment 1, and difference is that the formula of described soaking liquid is as follows:

[0126] Impregnation solution: mix vinyl acetate and initiator azobisisobutyronitrile in a weight ratio of 100:0.3, without adding oil-soluble dyes.

Abstract

The invention provides a preparation method of an impregnating-reinforced composite floorboard. The floorboard comprises a basal board and a surface board which is arranged on the basal board and formed by compounding one or more layers of veneers. The floorboard is prepared by the following steps: providing one or more layers of veneers and an impregnating solution comprising 100 portions of polymer monomer, 0-0.5 portion of initiator, 0-10 portions of oil soluble dye and 0-10 portions of floorboard addition agent by weight portion; providing a closed space and impregnating one or more layers of veneers in the impregnating solution in the closed space to trigger the polymerization of the polymer monomer and obtain the impregnating surface board; and gluing the surface board and the basal board to obtain the impregnating-reinforced composite floorboard. The preparation method of the impregnating-reinforced composite floorboard can improve the utilization rate of the monomer, solves the problem of environmental pollution caused by monomer volatilization and enhances the performance of the floorboard in hardness, surface impact, abrasion resistance, and the like.

Description

technical field [0001] The invention relates to the field of buildings, in particular to an impregnated reinforced composite floor and a preparation method thereof. Background technique [0002] At present, individual companies in the United States use gamma-ray radiation to initiate polymerization of high-molecular polymer monomers (such as methyl methacrylate monomers) impregnated in solid wood composite floor panels to obtain impregnated floors with excellent performance. However, the production cost of the gamma ray radiation method is high, and it is often used in the production of developed countries. However, the equipment investment is huge, the operation requirements are strict and complicated, and there are problems that high-energy ray radiation may endanger the health of workers, so it is not suitable for developing countries such as China. nation. [0003] Some companies and scientific research institutions use the existing international thermal initiation proc...
