Abstract
The present invention discloses a wearproof solid composite floor which comprises a base material plate blank layer (3), a decorative layer, a balancing damp-proof layer (5) and concave tenons (4, 6). The present invention is characterized in that the base material plate blank layer is formed by wood slices which are crossed and made of fast-growing forest trees by a modified urea-aldehyde resin adhesive coating layers in a heat pressing way, and then, single wood slices (2) and wearproof paper layers (1) after varnished by modified melamine resin are attached to the base material plate blank layer in a heat pressing way. The present invention has the advantages of high abrasive resistance and low free formaldehyde. The solid composite floor of the present invention can not easily deform due to expansion caused by wetting after water absorption, surface wood grains are clear and natural, service life can be prolonged by twenty times, the solid composite floor can be repaired more than five times, and the utilization rate of rare timber is increased more than thirty times.
Description
Technical field:
The present invention relates to a kind of laminar product production method, especially a kind of antiwear composite wood floor production method.
Background technology:
Along with scientific and technological progress and economic development, the human settlement constantly improves, and decorates gradually at home and popularizes, and wood floors increase day by day as the demand of floor decorative material.Traditional wooden floor be with the high-quality log after stripping and slicing processing, do the surface with paint or UV leaching paint and handle.This wooden floor wears no resistance, and using behind the certain hour must the waxing japanning, contains the materials such as benzene that are detrimental to health in the paint, and simultaneously, this wooden floor can not make full use of timber resources, and especially the harder high-quality timber utilization rate of quality is low.For overcoming the problems referred to above, people's process is at big quantity research, develop laminated flooring, it adopts wood chip and fast-growing woods wood small dimension wood to pulverize, again by making substrate layer with bonding agent mixing mold pressing machine-shapings such as pollopass, the substrate layer surface is pasted and is made decorative layer through the woodgrained paper of impregnation process, there is following defective in this floor: the one, contain a large amount of free formaldehydes and continuous bulk storage in this laminated flooring in the room, the serious harm health, the 2nd, make moist imbibition easily and be out of shape and scrap; The 3rd, the floor surface texture is nature not, lacks the sense of reality, and the 4th, this wood flooring can only disposablely be used, and can not repair.
Summary of the invention:
The objective of the invention is to overcome the prior art deficiency, provide a kind of and can improve the harder high-quality timber utilization rate of quality, abrasion resistance is strong, the antiwear composite wood floor production method that free formaldehyde is low, not moisture-sensitive imbibition distortion of the solid wood composite board that the present invention produces, surperficial wood grain clear and natural can improve 20 times application life, and can repair more than five times, the precious timber utilization rate can improve more than 30 times.Purpose of the present invention realizes by following technical proposals:
The solid wooden compound floor that the present invention produces comprises the base material plate blank layer, decorative layer, and balance damp-proof course and rebate,
Base material base layer is hot-forming through the modified urea-formaldehyde resin adhesive coating by the fast-growing woods timber section of criss-cross arrangement, hot pressing adds and posts through impregnated wooden monolithic layer of modified cyanurotriamide resin and wear-resisting ply of paper on base material base aspect again, adds at another side and posts through the moistureproof ply of paper of the impregnated balance of melmac.
Production method of the present invention is as follows:
1, produce modified urea-formaldehyde resin: get the raw materials ready by following component and weight ratio (1):
37% formaldehyde: urea: polyvinyl alcohol: modifier B=16: 9-11: 0.15-0.20: 0.2-0.25;
(2) add modifier B and urea after formaldehyde being placed container transfer PH to 7.0-7.5 with NaoH, the urea addition is the 4.5-6 weight portion;
(3) said mixture is heated to 25-35 ℃ of adding polyvinyl alcohol;
(4) be warming up to 90 ℃ and add urea 3.0-3.4 weight portion again, transfer PH to 4-5 and tested viscosity with NaoH;
(5) when viscosity reaches 1.5S, with the NaoH neutralization, make it pH value and reach 7-7.5 at once;
(6) be cooled to 80 ℃ of vacuum dehydrations, when viscosity arrives 3.5S, stop dehydration, add the insulation of surplus urea after 15-25 minute, transfer pH value to 7.0-7.5, be cooled to 40 ℃ with NaoH, standby;
Said modifier B is thiocarbamide, tannin, phenol any.
2, modulation bonding adhesive, press modified urea-formaldehyde resin: the blood meal dawn is white: modifier B: filler: ammonium chloride=100: 9-11: 1-2: 10-20: the 0.5-1.5 weight ratio, stir, leave standstill after 10 minutes standby;
Said filler is a starch, flour or corn flour any.
3, make the base material slab, fast-growing woods wood section central layer is gone ahead of the rest whole change coating adhesive after the processing, the crisscross assembly of again fast-growing woods timber being cut into slices, 0.8-1.2MPa typing 10-20 minute, again at 90-110 ℃, the 0.8-1.2MPa thermocompression forming got final product in 6-12 minute after the trimming
4, with abrasion-proof paper, balance moistureproof paper by the melmac dipping after, dry for standby;
5, the wooden monolithic of the high-quality timber slicing one-tenth that quality is harder is spliced into and the corresponding to whole plate of base material specification by grain of wood flower type, and standby by melmac dipping oven dry back;
6, with the wooden monolithic of impregnation drying, abrasion-proof paper and balance moistureproof paper are affixed on the backing material plate front and back respectively at 160-170 ℃ under the 3.0-7.0MPa pressure;
7, hot-forming big plate cooling and shaping is sawed tenon after 24-48 hour and be finished product.
Above-mentioned wooden monolithic also can not pass through impregnation technology, and directly by modified urea-formaldehyde resin at 90-110 ℃, fit with base material under the pressure 1-2MPa condition, through after the sanding after surperficial coating melamine resin drying, at 160-170 ℃, under the 3-7MPa condition impregnated abrasion-proof paper is attached to respectively on wooden monolithic and the base material again.
The present invention is by the pollopas modification, not only makes the requirement that is up to state standards of its adhesive strength, greatly reduces free formaldehyde content simultaneously, and wherein free formaldehyde content reduces more than 20 times, favourable health.The present invention replaces woodgrained paper by abrasion-proof paper after the impregnation process and precious timber wood monolithic, the abrasion resistance that improves solid wooden compound floor is more than 30%, kept the pure natural natural wood color, wood grain is truly clear, naturally warm, the present invention has also overcome laminated flooring and can only once use, the shortcoming that can't repair, can repair more than 5 times repeatedly, the application life of having improved the floor is more than 20 times, and the present invention simultaneously makes full use of the fast-growing woods material and substitutes precious timber, improved surplus the precious timber utilization rate 30 times, product detects through quality testing department, and every index is better than excellent grade standard.
