Description
Technical field
The invention belongs to polyurethane product technical field, be specifically related to a kind of urethane packaging sponge and preparation method thereof.
Background technology
Transport Package main raw in the market for furniture, drinks, valuables, the article such as frangible is Expandable Polystyrene (EPS) (EPS), light weight.EPS wrapped product segment space is replaced by gas, and therefore it is than plastics volume several times to tens times greatly, and EPS has advantages such as absorbing shock load, heat-proof quality is good, sound-proofing properties is good.But due to EPS pack foam exist frangibility, anti-deformation difference shortcoming so the difficulty that reclaims of Expandable Polystyrene (EPS) is also very large, and need to reheat the shortcomings such as shaping after reclaiming.
Urethane packaging sponge is a kind of shock resistant packaging material of environment-friendly type, its type variable is larger, resistance to shock loads ability is strong, good heat-insulation effect and the advantage that can recycle can well be used as wrapping material, this material mainly overcomes the shortcoming that traditional EPS wrapping material frangibility reclaims difficulty, this material adopts polyurethane material, its similar sponge foaming sky plays damping, heat insulation effect, the distinctive tensile property of urethane makes it in removal process, not easily be destroyed the integrity of structure, directly can reclaim the packaging for like product, have the advantage of energy-saving and emission-reduction.
Summary of the invention
The object of this invention is to provide a kind of urethane packaging sponge, there is the advantage that complete processing is simple, production efficiency is high, resistance loading capacity is strong, can repeatedly recycle; Invention also provides the preparation method of urethane packaging sponge, scientific and reasonable, simple.
Urethane packaging sponge of the present invention, is made up of component A and B component, with weight parts,
Component A:
B component:
TDI-805-25 part.
Described polyether glycol DEP-560D believes 3 functionality that federal chemical Industrial Co., Ltd produces, the polyether glycol of molecular weight 3000 by Zibo moral, and the goods cost made of this kind of polyvalent alcohol is lower, and bubble is better empty, and cushioning ability is strong.
Described polyether glycol POP-45D believes by Zibo moral 3 functionality that federal chemical Industrial Co., Ltd produces, and the grafted polyether polyol of molecular weight 1870, the Article Stiffness Determination made of this kind of polyvalent alcohol is large, and bearing capacity is high.
Described suds-stabilizing agent is suds-stabilizing agent 10366, steps the suds-stabilizing agent 10366 that figure produces, stable foam and adjustment abscess, the effect of emulsification foam material.
Described amine catalyst is amine catalyst A33, the A33 that aerification chemical product company of the U.S. produces, and mainly utilizes its high reactivity, plays stronger katalysis to gel reaction and foamable reaction.
Described linking agent is diethanolamine, has certain katalysis while stable foam structure to polyurethane reaction.
Described chainextender is BDO, and the molecular chain in reaction is expanded further, increases the snappiness of goods.
Described TDI-80 is produced by Wanhua Chemical Group Co., Ltd..
The preparation method of urethane packaging sponge of the present invention, step is as follows:
Each for component A raw material is added agitator mix, adjust constant material temperature 25 ± 2 DEG C, regulate agitator speed to 4000-5000r/min, the B component being preheated to 25 ± 2 DEG C is poured in component A and stirs 15-25s, mixture is poured in the mould being preheated to 40 ± 5 DEG C, the demoulding after 5-10min, obtains product.
The present invention compared with prior art, has following beneficial effect:
