The thickness of PVC film is 0.12-0.20mm described in the said step (5).
Practical implementation process of the present invention is:
1, oven dry splicing process: earlier timber is dried processing; To remove defect in timber (knot again; Resin, rotten etc.) the cutting clout rift grain finger of the short and small lumps of wood or timber become certain-length after, laterally piece together wide again or piece together the thick lumps of wood integrated timber that composes required specification.Because of its architectural characteristic that does not change timber itself, be still a kind of natural timber, not only have the texture of natural timber, and specious, material is even, and also overcome natural timber and be prone to warpage, distortion, the defective of cracking, its physical property is superior to natural timber.
2, dig material technology: the lumps of wood integrated timber of will pass through oven dry, splice, widen, thickening digs the notch end face that specific (special) requirements such as Hardware fitting are installed with four-side planing again.
3, polishing cleaning procedure: dig good timber, also will pass through repairing, polishing and process of cleaning.Mend some crack, hole and defectives that flat timber exists with putty.Send into sander then, remove the burr of wood surface, make its smooth surface smooth.Blow off attached to the wood of wood surface with dry gases at high pressure again and cut and dust.
4, wood surface lacquer spraying technique: dig good timber, all will carry out dipping lacquer and the surfacing of spraying paint.Dipping lacquer is that timber was soaked in the paint solution the inside regular hour, makes paint infiltrate the certain degree of depth of wood surface, forms the ability of wood preservation with this, also constitutes simultaneously at the bottom of the adherance of finish paint.General dipping lacquer will be operated about 2～3 times, to reach the favorable manufacturability ability.The dipping lacquer drying is carried out finish paint spraying (removing the section bar outdoor side surface) later on again, and topcoating is to make door and window have the ornamental means of color and regulation, generally will spray finish paint 2～3 times.The every dry and polishing that all will carry out regulation technology all over dipping lacquer or after spraying paint just can be carried out next then all over paint operation.The timber of the good paint of spray, general film thickness is about 120 μ m～170 μ m.
5, timber coating technique: timber just can be sent into the timber coating equipment and carry out the coating of PVC film through behind the lacquer spraying technique.Its principle is: utilize the PUR reaction type polyurethane hot-melt adhesive, thickness at the PVC of 0.12-0.20mm film, is posted on the surface of the outdoor side of solid wood profile, reach waterproof, anticorrosion, weather-proof, ageing-resistant purpose.PUR reaction type polyurethane hot-melt adhesive main component is isocyanate terminated base polyurethane prepolymer for use as.Its cementability and toughness (elasticity) scalable, and excellent adhesive strength, temperature tolerance, chemical resistance and resistance to ag(e)ing are arranged.With the material that contains active hydrogen, good bonding force is all arranged like any surface finish materials such as porous materials such as timber, leather, fabric, paper, pottery and plastics, metal, glass, rubber.It has following advantage: solvent-free, a liquid type, and not resembling need have dry run the solvent-based adhesive, and the environment pollution and the poisoning problem that do not exist because of solvent do not satisfy environmental requirement, and technique for sticking is easy, can adopt glue applying methods such as roller coating or spraying; Operability is good, can two clung bodies be fixed at short notice, so can change down built-up member over to the road manufacturing procedure fast, improves work efficiency; Heat-resisting, cold-resistant, water-fast steam, chemicals-resistant and solvent resistance are good, compare with former hot melt adhesive, because the cross-linked structure of reaction type hot-fusible bonding adhesive increases substantially listed performance and adhesive strength.Therefore, the timber cladding process is simple, feasible, quick, a firm technology.A coating equipment per minute just can be accomplished the solid wood coating technique of 30-50 rice, is well suited for large batch of production.
6, the one-tenth window technology of solid wood overlay film section bar: only need use the dovetail splicing process, just can become frame to become fan with the solid wood overlay film section bar that processes through 45 ° of cuttings.
In sum, compare with the traditional door and window material, be not difficult to find out, solid wood coats the film formed ornamental energy-conservation section bar of PVC and has more following advantage:
1, helps environmental protection and sustainable development.Because it is timber that wood is moulded the main composition of the energy-conservation section bar of composite decoration property, timber is a kind of renewable resource from forest, as long as Rational Management just can make it become inexhaustible, nexhaustible resource, just can continue, stably provide for society.Image-stone oil, aluminium, these non-renewable resources of steel will be a little less with a bit, finally can cause exhaustion.Particularly modern science and technology are constantly improved and development, to the cultivation of fast-growing woods, have improved the speed of growth of timber, timber are carried out technology such as modification, reorganization, have improved the application life and the utilization rate of timber.Trees are through photosynthesis, and absorbing carbon dioxide discharges oxygen, and the production of timber needs the energy hardly or only consumes the energy seldom, and therefore, to purifying air, it is dim that mitigation of global climate becomes, and has very important and unique effect.
2, the process energy consumption is low, the heat preservation energy-saving excellent performance.Because it is timber that wood is moulded the main composition of the energy-conservation section bar of composite decoration property; Through produce with practical application in find: wood is moulded composite door and window frame and is compared with alumium alloy door and window; From raw material to the finished product door and window; Timber fell with process in the spent energy lower than aluminium alloys, and pollution-free in production, use.Like the window of every production 1 ㎡, adopting the spent energy of aluminium windowframe is 30 times that employing timber window frame expends the energy.In use, because the coefficient of thermal conductivity of aluminium is 1580 times of timber, the coefficient of thermal conductivity of nylon also will exceed 1.5 times in timber.So the natural characteristic of timber has just determined timber to be best suited for the material as door and window, the door and window that processes is also more energy-conservation than plastics and metal door and window.
3, have the characteristic that wood is moulded two kinds of materials: because wood is moulded the energy-conservation section bar of composite decoration property is that wood is moulded homobium, so it has possessed wooden advantage of moulding two kinds of materials.Because the coefficient of thermal conductivity of timber and PVC is all very low,, wood also has very strong heat insulation, sound insulation, anti-pressure ability so moulding the energy-conservation section bar of composite decoration property.And timber has passed through oven dry finger technology, more can prevent warpage effectively, distortion, defectives such as cracking.Can know that in GB GB8624 " Classification on burning behaviour for building materials " PVC is decided to be the B1 level, be nonflammable material.So, coat the PVC film in the appearance of timber, remedied the deficiency of timber on waterproof, fire prevention, function such as anticorrosion, weather-proof effectively.
4, have excellent decorating feature: because timber itself is exactly a kind of natural organic material, have native texture, texture is honest warm, mellow and full soft and graceful, can give joyful visual characteristic and warm sensation.Add overwood and mould the plasticity of the energy-conservation section bar of composite decoration property, can also be very easy to design artificially and process various lines and decorative pattern.So wood is moulded the composite energy-saving section bar can process the door and window that lets the people admire, for the life of people's house brings unlimited enjoyment.
5, have lower cost of equipment input: traditional plastic-steel section bar, aluminium alloys bridge insulation thermal resistance section bar in the process of moulding, all needs a lot of moulding forms and large-sized processing equipment.Therefore, the input of mould and equipment and maintenance cost are very big.And wood mould the energy-conservation section bar of composite decoration property in the process of moulding, do not need moulding form and main equipment, therefore, all comparatively favourable to the equipment input.
6, section bar becomes window technology succinct: plastic-steel section bar as shown in Figure 1 becomes the window process to be: earlier PVC section bar 1, lined steel 2 are cut as required, connect the jail among again lined steel 2 being inserted in the die cavity of PVC section bar 1, again PVC section bar 1 is welded into frame at last; Separate type wood aluminum composite section bar as shown in Figure 3; Become the window process to be: respectively timber 6, aluminium alloy extrusions 9 to be cut as required earlier; Again timber 6 and aluminium alloy extrusions 9 are organized the angle separately and become frame, utilize nylon connector 8 and self-tapping screw 7 at last again wooden frame and aluminium frame mechanical connection; And wood was moulded the energy-conservation section bar of composite decoration property before becoming window, and it has been an organic homobium just that wood is moulded two kinds of materials, therefore only needed just can directly organize the angle and become frame after the section bar cutting.
7, has the vast market promotion prospect: because wood is moulded the energy-conservation section bar of composite decoration property; From becoming a useful person to becoming, possessed above-mentioned advantage in the process of window; So for general door and window processing factory; Do not need to drop into large-scale product moulding equipment and equipment for spraying again, exempted the processing technology of a lot of complicacies, mould composite door and window frame but can produce high-quality wood equally with timber window property.Therefore, it has possessed superior cost performance.Particularly along with constant development of economy; People improve constantly the requirement and the dependence of housing environment and working environment; Country and the continuous attention of society to environmental protection and energy-saving and emission-reduction; So wood is moulded the energy-conservation section bar of composite decoration property as a kind of building material, necessarily has the marketing prospect that can not replace.
Mould the energy-conservation section bar of composite decoration property through the formed wood of above-mentioned technology, have the characteristic that wood is moulded two kinds of materials.On each item indexs such as heat insulation, energy-conservation, sound insulation, resistance to compression, waterproof, fire prevention, anticorrosion, environmental protection, ageing-resistant, material-saving, all be superior to existing all kinds of door-window section bar.Compare with existing all kinds of door-window section bars, its section bar is few and simple with the processing technology link that becomes window, and the input of process equipment and energy consumption is low, has the vast market promotional value.
Can know that to sum up owing to adopted above-mentioned material and technological innovation, the present invention has compared with prior art respectively had very big progress on the performance at structure, technology, safety, maintenance, cost etc. easily.Therefore, will be more extensive also to the application of solid wood door and window.
