Abstract
The present invention relates to a modified wood product and a preparation method thereof. The method comprises the following steps: plastic monomers are dipped in wood gaps; a netty cross-linked structure is formed between each plastic monomer and each wood gap by radiation; finally, the modified wood product is made after the polishing process is carried out. The method has the advantages that the wood is smooth and clean and has a bright color, the appearance of the wood is elegant and simple, the inherent texture of the wood is kept, and the hardness, the abrasion-resisting strength, the corrosion resistance and the moth-preventing function of the wood are improved. The modified wood product has consilient exterior and interior after the wood and plastic are compounded, and has the advantages of the wood and the plastic. In addition, the mechanical property of the modified wood product is as good as that of rosewood. Thereby, the modified wood product can be used as materials for producing furniture, decorative boards, ceilings and floors in houses, and transport facilities.
Description
The present invention relates to a kind of processing method of timber being carried out the modification deep processing.
Present known timber is to be formed through cutting by round log, still favourable in addition residue sawdust, wood shavings and the tailing that is used in when cutting timber is made into artificial boards such as glued board, fiberboard, particieboard, core-board and splice plate through bonding, extruding, it all exists, and hardness is low, intensity is low, abrasion resistance is low, corrosion resistance is poor, moisture-proof is poor, the physical dimension poor stability, when being made into woodwork with above-mentioned timber, during as furniture holder, table, chair, ceiling and floorboard etc., all need bepaint, to reach bright and clean, attractive in appearance, waterproof, corrosion-resistant purpose.
The object of the present invention is to provide a kind of maceration extract is immersed in the timber to make maceration extract and timber constitute the method for production of the wood plastic composite of one through radiation again.
The object of the present invention is achieved like this: the styrene maceration extract is immersed between the birch inner pore, between overshoot initiation maceration extract and birch hole, constitute cross-linked network, its method for production is, at first with impregnated article birch in super-dry is placed on impregnating autoclave, reduce pressure with vavuum pump, its pressure is 0.08Mpa, to remove the air between timber pore, inject the styrene maceration extract to impregnated article birch thereupon, in the injection timber pore, its injection rate is so that the unit weight of timber reaches 1-1.2g/cm
3Till, with moving in the radiation chamber behind the birch usefulness composite plastic film package encapsulation, use Co thereupon
-60Uniform irradiation is carried out in the source, and exposure dose is 100-200KGY, forms through polishing at last.
Owing to adopt such scheme, timber is carried out modification to be handled, can make the timber bright and clean, bright in colour, clean mark, elegant simple and unsophisticated, kept the intrinsic texture of timber, unit weight is big, improved hardness, abrasion resistance, compression strength, toughness, weatherability, corrosion resistance and water-resistance, favorable moth-proof, physical dimension is stable, and it is the same outside and inside that wood is moulded compound back, and have the advantage of timber and plastics concurrently, its mechanical performance can compare favourably with redwood, and it can be widely used in manufactures construction material, furniture, the woodcarving material, sports equipment, the weaving facility, musical instrument, the house decoraton plate, the floor, the ornament materials of ceiling and various transport facilitys does not need japanning during use.
The present invention will be further described below in conjunction with embodiment.
Embodiment one
The styrene maceration extract is immersed between the birch material hole, through Co
-60Constitute cross-linked network between radiation initiation styrene maceration extract and the birch timber pore, make it become wood plastic composite, its concrete method for production is, at first with dipping articles birch timber in super-dry is placed on impregnating autoclave, reduce pressure with vavuum pump, its pressure is 0.08Mpa, to remove the air between timber pore, be convenient to the styrene maceration extract is injected between timber pore, its injection rate is 0.43-0.53g/cm
3, so that the former unit weight 0.57-0.67g/cm of birch
3Reach 1-1.2g/cm
3Till, with moving in the radiation chamber behind the birch timber usefulness composite plastic film package encapsulation, use Co thereupon
-60The source is shone, the birch timber that when irradiation, should constantly overturn, so that birch timber can access uniform irradiation, exposure dose is 100-200KGY, makes through polishing at last.
Embodiment two
Except that maceration extract was selected methyl methacrylate for use, its method for production was with embodiment one.
Embodiment three
Except that maceration extract was selected vinylacetate for use, its method for production was with embodiment one.
Embodiment four
Except that maceration extract was selected acrylonitrile for use, its method for production was with embodiment one.
Embodiment five
Except that impregnated article were selected toothed oak wood timber for use, its method for production was with embodiment one.
Embodiment six
Select for use the pine timber except that impregnated article, its method for production is with embodiment one.
Embodiment seven
Except that impregnated article were selected look wood timber for use, its method for production was with embodiment one.
Embodiment eight
Select for use the cotton wood except that impregnated article, its method for production is with embodiment one.
Embodiment nine
Except that impregnated article were selected rubber wood timber timber for use, its method for production was with embodiment one.
Claims (1)
1. the method for production of a wood plastic composite, it is characterized in that: at first with impregnated article birch in super-dry is placed on impregnating autoclave, reduce pressure with vavuum pump, its pressure is 0.08Mpa, to remove the air between timber pore, inject the styrene maceration extract to impregnated article birch, its injection rate is so that the unit weight of timber reaches 1-1.2g/cm thereupon
3Till, with moving in the radiation chamber behind the birch usefulness composite plastic film package encapsulation, use Co again
-60Uniform irradiation is carried out in the source, and exposure dose is 100-200KGY, constitutes cross-linked network to cause between maceration extract and the birch timber pore, forms through polishing at last.
