Abstract

The utility model discloses a composited-structure heat-preservation and sound-proof board composited with multilayer wooden single board and foam plastics, which belongs to the technical field of the producing of plywood in the wood industry. The heat-preservation and sound-proof board is characterized in that the multilayer wooden single board which functions as the surface board and the foam plastic core board which has heat-preservation effect are agglutinated into composite board. The heat-preservation and sound-proof board has the advantages of sound-proof and heat-preservation effects of energy-saving building materials; and the composite board can save earth and energy; and the natural ligneous texture facilitates to adjusting the indoor environment. The composite board can be pasted on walls directly and also can function as partition board to perform heat-preservation, sound-proof and ornamental effects.

Description

The heat-preservation sound-insulation board that veneer and foamed plastics are compound
Affiliated technical field
The invention belongs to veneer and manufacture technology of composite material field in the timber industry, relate to the manufacture method of veneer and foam composite material.
Background technology
Along with the development of World Economics, the consumption of various countries' energy is more and more higher, and the influence to environment, society etc. that is brought thus also causes people's great attention day by day.Heat insulating material is to realize that the most basic condition foam heat insulating material that heat preservation energy-saving reduces discharging mainly is polystyrene and polyurethane foam plastics, have light weight, insulation, heat insulation, sound absorption, shockproof, corrosion-resistant, anti-mould, characteristics, the sandwich composite inside and outside wall plate of major product variety steel screen frame such as machine-shaping makes things convenient for, construct, application cost is low; The metal composite filled board; Directly be affixed on exterior wall again with coating ornamental surface or embossment floated finish with the polymeric modification adhesive mortar; The dowel fixes of employing is also arranged to metope, use the pane fibrous protective layer again, outermost layer is an architectural surface; The lightly constructed and simply equipped building plate that the two sides steel plate is sandwich.The veneer product of China is because competition with low content of technology, unordered is in a disadvantageous position the sector simultaneously.Therefore utilizing existing plywood production technical equipment to produce multifunctional product is the task of top priority.
Summary of the invention
Veneer is Yu the compound heat-preservation sound-insulation board of foam is a kind of composite board that collects insulation, sound insulation and decoration for one that utilizes existing plywood production technical equipment to produce, its structure spy is a center core layer Wei foam [2], and two surfaces are the crisscross multilayer veneer [1] of texture.
Manufacture method is to adopt the technology of secondary hot pressing, rotary-cut or slicing with trees become veneer, the crisscross veneer that is pressed into of multilayer veneer manufactures the veneer dash board that presses and the foam plastics slab secondary glue laminated of making middle layer plate the composite board of heat preservation and soundproof again.The thickness of veneer is not limit, and seeds can be the living willows of speed etc., do to decorate the section of outermost veneer of time spent with precious timber.Foam plate expanded polystyrene (EPS), extruded polystyrene and polyurethane foam plastics, kind and thickness are decided according to the multifunction board purposes.Make central layer as the composite plate that partition wall is used with thicker foamed plastics, the composite plate that is used for wall thermal insulating and decoration adopts thin foamed plastics central layer.
Key technology is bonding adhesive and the secondary hot pressing technology that adopts.The urea-formaldehyde resin adhesive of hot pressing for the first time, conventional hot-press technology.The bonding adhesive of hot pressing for the second time must adopt not only the timber to polarity to have the gummed effect simultaneously but also nonpolar foamed plastics is had the glue of gummed effect.Bonding adhesive is 4: 1 with the mixture of homemade polyvinyl acetate emulsion glue and isocyanates, its proportioning.According to the temperature capacity of these three kinds of foamed plastics, the hot pressing temperature of employing is respectively 60 ℃, 65 ℃ and 100 ℃.For Fang Zhi foam can not be compressed the effect of insulation, the composite board according to different-thickness in the hot pressing adopts different finger gauges, and pressure is that top board touches finger gauge.
Veneer is Yu the advantage of the compound heat-preservation sound-insulation board of foam:
1. the sound insulation, the heat insulation effect that have energy saving building material, joint soil is energy-conservation, and it is even to have engineering property simultaneously again, and specification is flexible and changeable, does interior wall dividing plate time and labour saving, and grain of natural wood helps to regulate the advantage of indoor environment.
2. production technology is simple, can utilize existing plywood production technical equipment.
As interior wall building heat preservation sound isolating decorative material, can directly be affixed on the interior wall, also can make indoor partition board.
Description of drawings
The structure of Fig. 1 heat-preservation sound-insulation board
Embodiment 1
As shown in Figure 1, the top layer is that three layers of thick board using poplar board texture of 1.0mm are crisscross, adopts urea-formaldehyde resin adhesive to be hot pressed into veneer [1], is pressed into heat-preservation sound-insulation board with the thick expanded polystyrene (EPS) [2] of 26mm by following technological parameter again.
Bonding adhesive is the mixture of homemade polyvinyl acetate emulsion glue and isocyanic acid glue, and proportioning is 4: 1.
Resin added: 100-150g/m 2
Hot pressing temperature: 60 ℃
Hot pressing time: 1 hour
Control the thickness of heat-preservation sound-insulation board during hot pressing with finger gauge.
Adopt method and structure provided by the invention, the main physical parameters of the heat-preservation sound-insulation board of making:
Coefficient of thermal conductivity---0.041 (W/mK)
The sound absorption coefficient of different frequency
Realized the goal of the invention of insulation, sound insulation.
