Description
Technical field
The present invention relates to padded coaming field, specifically a kind of preparation method of high performance polyurethane cushion pad.
Background technology
In recent years, based on the viewpoint for mitigating carrying capacity of environment, the resin from plant obtained from plant resources is sought, instead of
The resin from oil using petroleum resources as raw material.That is, the resin from plant, by from the CO in the absorption air of one side2, one
While the raw material obtained by photosynthesis growing plants is formed, even if being handled corresponding to the burning after by CO2Row
It is put into air, as a result will not also causes the CO in air2Amount increase, i.e., so-called carbon are neutralized, therefore, contributed to as one kind
Mitigate the material of carrying capacity of environment and noticeable.
Polyurethane be exactly it is a kind of typically can carbon neutralize resin, polyol component used in the raw material of polyurethane, so far
Untill the present, it is known to using the PPG from oil, PEPA as representative polyalcohol, in addition, there is known make
By the use of being used as castor oil or the castor-oil plant oils polyalcohol of castor oil derivative from plant.
On the one hand, polyurethane composite buffering material is due to excellent resiliency, being widely used in the vehicles such as automobile use
On cushion, also human-body safety can be effectively protected in traffic accident.Based on the reason for same, polyurethane buffering material also extensively should
With on automobile front/rear collision bumper, the extent of damage after automobile collision accident can be effectively reduced；With on the airplane parking area of helicopter,
With good damping and buffering effect；With on shoe-pad or sole, can greatly alleviate in walking process with ground
Impact, can preferably protect foot, slow down walking fatigue significantly, avoid athletic injury.Used in the shield of human body key component
On tool, the athletic injurys such as the fracture after falling down can be prevented.But for middle-to-high end car market, cushion is not required nothing more than, is had when sitting
There is good buffering sense, it is also desirable to have very balancedly hardness and resilience (i.e. not really up to the mark only soft), and it is excellent resistance to
Long property (after long-term use of, the change such as elasticity, hardness, thickness is small).
On the other hand, the domestic polyurethane automobile cushion pad produced at present can not meet the requirement of antibacterial, therefore can only use
In low side automobile market or some other to the less demanding market of antibacterial.The preparation of antimicrobial form automotive buffer block rises in the world
The last century 90's is come from, based on inorganic silver ion antimicrobial agent and organic vanilla aldehydes antiseptic, but these antiseptics
Poor heat resistance, facile hydrolysis, the term of validity are short, it is difficult to meet the needs of middle-to-high end car market.
