Description
Technical Field
The invention belongs to the technical field of polyurethane sponge, and particularly relates to polyurethane sponge taking aliphatic isocyanate as a raw material and a production method thereof.
Background
Polyurethane sponges, all known as polyurethane sponges, were first synthesized by bayer in the united states in 1937 the last century, and were first used in spacecraft in the united states. After entering the civil field, the utility model is applied to a plurality of fields of the people's countryside, such as mattress sofas, high-speed railway seats, white household appliance fillings and the like, and high-end female bras, medical use and the like.
Polyurethane sponges are classified into polyester types and polyether types, and are obtained by reacting polyester polyol or polyether polyol with isocyanate, respectively. The two types of sponges are characterized by each and are used in different fields. However, most of the polyester type and the polyether type are produced by using aromatic Toluene Diisocyanate (TDI) or diphenylmethane diisocyanate (MDI) as a main material. These sponges are susceptible to oxidation and aging to yellow due to the presence of the aniline structure.
The sponge produced by using the aliphatic cyanate as the main material has excellent oxidation resistance, ultraviolet radiation resistance, aging resistance and other characteristics due to no aniline structure. However, because aliphatic isocyanates are much less chemically reactive than aromatic isocyanates, conventional catalyst combinations cannot be used to foam aliphatic sponges.
The prior art discloses a production method of aliphatic prepolymer (Chinese patent CN 201410164435. X) and a process for producing aliphatic polyurethane sponge by using the prepolymer (Chinese patent CN 201110183914.2),
