Description
Technical field
The present invention relates to foam sponge technical field, particularly relate to a kind of soft pro-skin silica gel polyurethane foam sponge pad.
Background technology
Polyurethane low resilience urethane foam resilient foam, due to the comfort property of its excellence, has been widely used in household articles, automobile, footwear
The field such as material, medical apparatus and instruments, polyurethane rebound foam, due to the molecular structure of its uniqueness, has higher comfort property, when being subject to
During to certain pressure, polyurethane rebound foam can change shape along with pressure, makes pressure be evenly distributed, and reduces local pressure
Point, after pressure is released, its shape the most slowly returns to original state.But due to the hole-closing structure of himself, polyurethane slow rebound steeps
The permeability of foam and damping sound absorbing capabilities are poor." synthesis of soybean oil polyol and grinding of polyurethane low resilience urethane foam resilient foam performance
Studying carefully " author has been synthesized modified soybean oil by maleic anhydride and soybean oil, then with diethylene glycol and modified soybean in a literary composition
Oil reacts under the catalysis of potassium hydroxide, has synthesized soybean oil polyol.The soybean oil polyol of recycling synthesis is prepared for greatly
Oleum Glycines polyol based polyurethane low resilience urethane foam resilient foam, in article, the stretching to soybean oil polyol based polyurethanes low resilience urethane foam resilient foam is strong
The mechanical properties such as degree, elongation at break and 40% degree of compression are studied, and find that the use of soybean oil polyol can improve polyurethane
The permeability damping capacity of low resilience urethane foam resilient foam and sound absorbing capabilities, but the decline of mechanical property can be caused, propose to increase foaming
Agent water consumption or raising isocyanate index, can have higher ventilative at soybean oil polyol based polyurethanes low resilience urethane foam resilient foam
On the premise of performance, damping capacity and sound absorbing capabilities, improve its mechanical property.
Although author is by soybean oil modified thus synthesize soybean oil polyol based polyurethanes rebound foam, improve slow
The permeability of recovery sponge, damping capacity and sound absorbing capabilities, but the bad shortcoming of its bad mechanical strength, toughness reduces material
The service life of material and the comfort level of people, affect the quality of product, does not promotes expanding economy, and its slow time prepared
Playing sponge and can't fully meet the nowadays people's various demands to foam-rubber cushion, so needing further to improve, improving it
Other performances such as mechanical property, heat stability, hydrophobicity, expand application and increase the service life.
