Point.
Although pallet PP Pipe Compound disclosed above solves the defect of partial tray raw material, but material function is not comprehensive,
Effect is not still highly desirable, meanwhile, with inorganic salts such as calcium carbonate, nano-calcium carbonate and silicate as inserts, not easily biological-degradable,
Easily make alkalization of soils, severe environmental pollution can be caused, and antioxidant is industrial chemicals, can cause secondary pollution.
Carbon fiber is in traditional use in addition to as heat-insulating material.It is many as reinforcing material be added to resin, metal,
In the materials such as ceramics, concrete, composite is constituted.Carbon fiber has turned into the most important reinforcing material of advanced composite material.By
In carbon fibre composite have it is light and it is strong, light and just, high temperature resistant, corrosion-resistant, endurance, physical dimension good stability and set
Meter property it is good, can large area global formation the features such as, the every field in Aero-Space, defence and military and civilian industry is obtained extensively
General application.Carbon fiber can be processed into fabric, felt, seat, band, paper and other materials.High-performance carbon fibre is manufacture advanced composite material
Expect most important reinforcing material.
CNT has high intensity, toughness and elastic modelling quantity in terms of mechanics.Its elasticity is up to 1TPa, about steel
5 times, the elastic modelling quantity with diamond is almost identical, and its elastic strain is about 5%, reaches as high as 12%.No matter is CNT
It is that intensity or toughness are all far superior to any fibrous material.Using CNT as composite material reinforcement body, can show good
Good intensity, elasticity, fatigue resistance.CNT not only has excellent mechanical property, also with excellent electricity, optical
Energy.Many experiments show, compared with other reinforcements (such as carbon black, carbon fiber or metal charge), CNT is to polymerization
The improvement of thing based composites electric conductivity is more notable, and because CNT has nano-grade size, addition is few, its
Polymer composites can also strengthen its mechanical performance and other performance while good electric conductivity is obtained, while also
Be conducive to the design of macromolecular material other performance, therefore suffer from extensive concern.
But the active group of carbon fiber, carbon nano tube surface is considerably less, the interaction with macromolecular material group is very
It is weak, and the draw ratio and specific surface area of CNT are big, divide in the polymer for be prepared be difficult to during polymer composite
Dissipate uniform, agglomeration easily occur, it is impossible to embody its excellent properties.Therefore it is modified to the surface of CNT to seem extremely
It is important.
To sum up, science compounding functional material, functional characteristic that is lasting, improving plastic pallet PP Pipe Compound comprehensively, with organic
Degradable raw material replaces Inorganic Chemicals, prepares a kind of material and the good environment-friendly type plastic pallet PP Pipe Compound of performance very
It is necessary.
