Description
Technical field
The invention belongs to wood plastic composite preparing technical field, particularly a kind of method utilizing peanut hull meal to prepare PVC base wood-plastic composite material.
Background technology
Containing wood powder and plastics in wood plastic composite, therefore matrix material has had the advantage of timber and plastics concurrently: 1. good processing characteristics.Wood plastic composite includes plastics and fiber, therefore, has the processing characteristics that same timber is similar, can saw, can follow closely, can dig, and use carpenter's utensil to complete, and nail-holding ability is obviously better than other synthetic materialss.Mechanical property is better than wood materials.Nail-holding ability is generally 3 times of timber, is 5 times of shaving board.2. good strength property.Wood plastic composite includes plastics, thus has good Young's modulus.In addition, due to including fiber and through fully mixing with plastics, thus there is the resistance to compression suitable with hardwood, the physical and mechanical properties such as counter-bending, and its wearing quality is obviously better than normal wood material.Surface hardness is high, is generally 2 ~ 5 times of timber.3. there is water-fast, corrosion resistant performance, long service life.Wood-plastic material and products thereof, can anti-strong acid-base, water-fast, corrosion-resistant compared with timber, and not bacterial growth, is not easily damaged by worms, not long fungi.Long service life, can reach more than 50 years.4. excellent adjustable performance.By auxiliary agent, the changes such as plastics can be polymerized, foam, solidify, modification, thus the characteristic such as density, intensity changing Wood-plastic material, can also reach anti-aging, anti-electrostatic, the particular requirement such as fire-retardant.
Pericarppium arachidis hypogaeae is as the tankage of agricultural-food; abundant source is had in China; according to the study; containing a large amount of organic compound in Pericarppium arachidis hypogaeae; as xylogen, Mierocrystalline cellulose, protein, Sitosterol, saponin etc.; its powdered granule formed after pulverizer is pulverized or be Powderedly called peanut hull meal, can be used as the wood powder of wood plastic composite.From the angle of raw materials for production, wood plastic composite slows down and eliminates the public hazards pollution of plastic refuse, also eliminates Pericarppium arachidis hypogaeae waste material and piles up and burn the pollution brought to environment.
Because wood plastic composite has so many performance, just decide it will be widely used.1. construction industry.The floor of making by Wood Fiber Composites than superior many in low wood fibre board performance at present, not breathing, waterproof, surface aesthetic.If meet material for multilayer coextrusion section bar, internal layer adopts reclaimed materials, and outer employing virgin material, the every mechanical property of the goods made can compare favourably with hardwood products.2. the application of automobile industry.In recent years, Wood plastic boards, with its rational price, superior performance, is applied and is increased in automobile decoration material, as automobile door-plate, after put thing case, luggage case sidewall, seat plate etc.3. other industry.Except traditional industry, the Application Areas of matrix material constantly expands, started at present apply as pallet, flowerpot, handle for tool, office appliance, attack the engine components such as fast highway route marker, acoustic board and audio amplifier.
PVC price is lower, for the development of wood plastic composite provides price advantage.Polyvinyl chloride resin is simple linear polymer, has thermoplasticity.Due on molecular chain every a carbon atom just by the Cl atom that a negatively charged is stronger, thus molecular chain has stronger polarity, and the interaction force between macromolecular chain is large, hinders the Relative sliding between molecular chain.Therefore polyvinyl chloride resin macroscopically shows certain rigidity and hardness, and has good chemical resistance.
