Abstract
The present invention discloses a surface hardening treatment method for giving simulation texture to the surface of wood. The spring wood on the surface of the softwood is removed, wherein the spring wood and summer wood are obviously different on the surface of the soft wood; and then the surface of the softwood is further treated to form grooves of 0.5~5 mm, and then the groove is filled with hard resin; after the resin is cured, the original spring wood is hardened and the simulation texture is formed on the surface of the wood; thereby the softwood after treatment can be used for floor, furniture and indoor decorating. The present invention has the advantages of simple processing technology, low equipment investment, low production cost, small pollution, natural and beautiful color and texture.
Description
Technical field
The invention belongs to timber processing and material field, the method that particularly a kind of Wood simulation wood grain surface harden is handled.
Background technology
Timber is one of four big materials, and timber also is unique reproducible material in the four big materials, is widely used in building, decoration, furniture, floor etc.Because natural, the environmental protection of timber has beautiful natural texture, gloss, is with people one of material of affinity to be arranged most, and is subjected to more and more consumers' favor.
In recent years, China's rapid economic development, development of real estate is rapid, has driven developing of China's adnornment industry, upholstery, floor industry, and consumption of wood more and more comes greatly.On the other hand, China implemented since wildwood keeps engineering from the nineties in last century, and it is fewer and feweri that China can be used for the hard wood on furniture, floor, domestic timber can not satisfy far away China's furniture, the demand of board industry.For solving the imbalance between supply and demand of China's timber anxiety, China on the other hand, solves China's timber breach by cultivating a large amount of artificial fast-growing, high-yield woods on the one hand from a large amount of hard precious timber of external import.China cultivates through the artificial fast-growing woods in more than 10 years, and the fast-growing woods timber reserves is quite abundant, and China has become one of country that the fast-growing woods timber reserves is maximum in the world.The fast-growing woods timber varieties of trees of China mainly contains masson pine, larch, pinus sylvestris var. mongolica, China fir, poplar etc.Masson pine, larch, these speed of pinus sylvestris var. mongolica are given birth to softwood, and general material is softer, and can not be used for the place of load-bearing such as floor, furniture.But these softwoods, early the late wood distinguishes obviously, and late wood's quality is hard usually, and the early wood quality is softer.Therefore,, substitute softer early wood, make early wood become the same with the late wood hard, thereby make speed give birth to the softwood hardening, and they can be used for load-bearing places such as floor, furniture with hard material if can remove the softer early wood of these wood qualities.On the other hand, softwood color dullness can not satisfy the vast consumer's of liking to be beautiful requirement.Therefore, if can give speed and give birth to the more color of softwood when timber harden, that must improve their value.
At present, aspect softwood sclerosis utilizes, compressed wood, impreg, dipping compressed wood etc. are arranged.These several sclerosis wood processing techniques need press device, equipment and complex process, and equipment investment is big, the production cost height.In addition, because there are the size bounce-back in compressed wood and dipping compressed wood, impreg pollutes bigger, reasons such as texture and the not enough natural beauty of color, and fail well to commercially produce.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art part, primary and foremost purpose of the present invention is to provide a kind of method of Wood simulation wood grain surface harden processing.This timber hardening process is simple, and production cost is low, and wood color texture natural beauty can be used as raw material such as floor, furniture, interior decoration.
Purpose of the present invention realizes by following technical proposals: the method that a kind of Wood simulation wood grain surface harden is handled comprises the steps:
(1) morning the late wood distinguish tangible soft wood and be processed into sheet material.
(2) timber after adopting drying means to above-mentioned processing carries out drying, with the drying of wood to moisture content 5～16%.
(3) early wood on dried timber surface is removed, kept the late wood, handle forming the dark groove of 0.5～5mm at wood surface.
(4), make the dust of wood surface remove clean with above-mentioned wood surface cleaning.
(5) hard resin evenly is applied to wood surface, makes hard resin enter groove, groove is filled and led up; After treating that hard resin solidifies, hard resin becomes hard material, and this hard material has replaced original softwood part, and makes the whole hardening of wood surface.
(6) timber is carried out sanding surface and handle, yet it is beautiful from hard Wood-grain-imitating that wood surface is presented, obtain emulation grain surface sclerosis timber.
In order to realize the present invention better, the late wood distinguished tangible soft wood and comprised softwood etc. described morning, and described softwood comprises larch, pinus sylvestris var. mongolica, masson pine, redwood, pesudotsuga taxifolia, pine or pinus yunnanensis etc.
The specification of described sheet material is long 300mm～4000mm, wide 50mm～4000mm.
Described drying means comprises the steam heated drying means, also can adopt the direct or indirect heat drying of furnace gas, vacuum drying etc.
Described hard resin comprises phenolic resins, epoxy resin, pollopas, polyurethane resin or water-based carbimide etc.
The normal temperature cure condition is 25 ℃ of curing 60min down in the described step (5).
The color of described hard resin comprises white, yellow, brown or the like color.
The present invention compared with prior art has following advantage and beneficial effect: it is simple that the simulation wood grain surface harden timber of the inventive method preparation has processing method, equipment investment little (5～200,000 yuan), and production cost is low (120～300 yuan/m
3), pollute advantages such as little, wood color texture natural beauty.Wood-grain-imitating cure process of the present invention will have important impetus aspect China's fast growing wood high value added utilization, and the nervous situation of solution China timber supply and demand and the sustainable development of wood-processing industry are played important meaning.
