Abstract
Hybrid composite wood material uses natural fibres mixed with MDI glue (Special Cyanic Acid Ester Glue). The fibres comprise crushed wood, bamboo, hemps and/or straw. The material density after processing is 550-750kg/m3. The MDI glue is zero formaldehyde and the composite material is non-toxic and water resistant. The material is moulded in a frame under heat and pressure. The composite is an environment-friendly material, and does not possess the natural defects of natural wood, such as cracks, stains, warping, rot and other micro-defects. The new timber has a natural texture and grain and is corrosion resistant, flame-retardant and waterproof, and can be painted and sanded. The production process produces no industrial waste or waste water and is low noise.
Description
Novel sustainable WOOD composite material characterisation and fabrication methods
Description
1. What is the Novel Sustainable-Wood 1.1 Green-Wood, materials research using advanced composite materials, multi-combination formula of technology using high-tech means to apply a small amount of powder processing and polymerization of high-tech polymer materials, new environment-friendly material, and he effectively removed the natural wood natural defects, such as cracks, stains, warping, rot and other micro-defects, the new timber is designed with a natural texture and grain of wood, green wood in terms of performance there is corrosion, flame-retardant, waterproof timber such as do not have the characteristics.
1.2 Sustainable-Wood can meet the human needs of a variety of wood products, along with painting and sanding without significantly reducing the cost of production, the entire production process, non-industrial waste, non-industrial waste water, low noise, in line with the European Community and the State The industrial production of environmental protection requirements of the products fully meet the large-scale industrial production.
At present green wood can die through different means of processing and processing of wood into different models and different colors, you can easily adapt to a variety of application requirements and performance needs.
Research on new materials, production of hair has been completed and materials for all aspects of the new formula will be under the protection of the patent as a new generation of architecture and furniture is now a major environmental and application of wood.
Green wood is through a special high-tech means of wood, as well as high-fiber, Volatile non-toxic, formaldehyde emissions to zero, is the true sense of the green wood.
2. The advantages of Sustainable-Wood 2.1 New material and new green wood, can be compared from two aspects of note: Analysis of the traditional characteristics of wood: 2.1.1 The advantages of the traditional wood Machinability: You can saw, can be planed, can be nailed, multiple processing convenience.
2.1.2 Toughness is good, there is a certain degree of hardness: You can do so shaped, bent, there is a certain degree of hardness, resistance to external damage.
2.1.3 Have a certain load-bearing capacity: for example, traditional architecture of the room Liang.
2.1.4 Density is small, light weight.
2.1.5 High insulation, in the case of dry non-conducting.
2.1.6 Wood and colors: the natural wood grain with the irregular, natural patterns beautiful.
Defects and non-renewable nature of Waterproof, anti-corrosion ability is poor: the need for a special anti-corrosion maintenance, special anti-corrosion properties of the wood is still good, such as antique furniture and wood materials, red sandalwood, pear, but playing mostly valuable tree species, higher prices, it is impossible to use a large area. Today's timber market application of the material is not very good most of the material even after the antiseptic treatment life expectancy is 3-5 years, beginning started to decompose.
Easy deformation, Alice crack, mildew: especially in outdoor conditions susceptible to moisture and sun exposure situations prone to the above phenomenon. Vulnerable to pests against: The main thing against termites. Flammable: In the fire environment can easily cause a fire. Great efforts on the destruction of forests.
3. Sustainable-Wood Formulas 3.1 The main raw material, fuel quantity and source of cellulose fibers bamboo powder, woody materials mainly trails wood, branches wood, wood processing residues, etc. 3.2 The materials Calcutta hemp, sisal hemp, is second in command.
3.3 The wheat straw is third materials for this man made wood.
4.Glue MDI 4.1 An environmentally friendly wood adhesive, characterized in that the adhesive polyvinyl alcohol, completing agent, starch, cross-linking as the main ingredient, after feeding mix, regulate PH value, heating temperature, heat reaction, cooling, discharging procedures are the main agent with a polyisocyanate as curing agent.
4.2 An environmentally friendly wood adhesive, mainly used for wood-based panel processing industries. The main features are: the adhesive polyvinyl alcohol, complexing agent, starch, cross-linking as the main ingredient, after feeding mixture, adjusting pH, heating temperature, heat reaction, cooling, discharging procedures are the main agent used for the multi-isocyanate curing agent. The main advantage is a water-resistant glue products, good bonding strength than the urea-formaldehyde resin has increased, there is no formaldehyde emission, the production plant there is no irritating odor. Used for plywood, particleboard, fiberboards manufacturing, greatly improve the production and use of the environment.
4.3 An isocyanate (MDI) adhesive characteristics of isocyanate referred to as MDI adhesive glue, is kinds of probe red-brown liquid product, and does not contain formaldehyde. With the manufacture of high-performance The performance of wood-based panel. In addition, they also have a number of technological advantages.
MDI adhesive superior to all the traditional materials of surgical adhesive, it hot time is short, water, weather excellent performance, low glue consumption. It's the following features.
4.4 The active hydrogen-containing functional groups, in addition to an Isocyanate-based reaction.
Thus, in wheat orange board manufacturing, it can be water, cellulose, lignin, urea-formaldehyde glue and other reactions to form a crosslinked network, reaching to the strengthened bonding purposes.
4.5 soluble in organic solvents, because of its small molecular volume, it is easy penetration were a number of porous materials have been bonding, wheat straw debris with a porous of features, resulting in improved bonding performance.
4.6 It has been bonding with the adsorbed on the surface water and aquifer material oxides and other chemical reactions or bonding in the alkaline surface being on the self-polymerization, these reactions result in the interface to generate chemical bonds, because greatly improved the performance cemented.
The Figure 1 Shows a composite panels process from material to composite* Figure 2 Shows a schematic of the composite consolidation Fig 3 Shows hybrid composite material concept image.
In figure 1 give all the ideas about how to process from materials to composite panel and all the manufacture is a under favorable circumstances. The figure 2 is schematic of the composite consolidation this method can change the press load and change forms make different size and different density thickness.
