Abstract
The invention discloses halogen-free flame retardant slowly-recoverable memory foam which is prepared from the following raw materials in parts by weight: 20 to 50 parts of polyether glycol 1030, 4 to 10 parts of polyether glycol 2000, 23 to 56 parts of MDI, 8 to 20 parts of slowly-recoverable polyether, 8 to 20 parts of white oil, 9 to 24 parts of a halogen-free flame retardant, 1.2 to 3 parts of an opening agent, 0.02 to 0.5 part of an amine catalyst and 0.3 to 0.9 part of silicon oil. The product retains certain crosslinking degree, so that the product is insensitive to low temperature and cannot be hardened in winter; the added slowly-recoverable polyether LR-00 is insensitive to temperature, so that the influence on the product due to the environmental temperature is low; during use, the halogen-free flame retardant slowly-recoverable memory foam can keep cool in summer and warm in winter; the comfortableness is greatly improved, and the slow recovery effect can be also improved.
Description
Technical field
The present invention relates to sponge preparation field is and in particular to a kind of halogen-free flameproof low resilience memory foam.
Background technology
Low resilience memory foam is a kind of will not to be rebounded immediately by external force pressure deformation but delay several seconds time slow
The sponge of reduction, it is soft, has significant low resilience ability, can absorb impulsive force, reduce vibrations, the release of low bounce-back power
Ability is strong, and the article such as the medicated cushion made using slow-recovery sponge, medicated pillow, mattress can make one to feel more comfortable, natural.Sponge
Product easily burns when running into naked light or red-hot flame, and low resilience memory foam is also such, once burning is just difficult to flutter
Go out, the dense smoke of generation also has certain toxicity, fire-proof sponge adds fire retardant can play fireproof effect when prepared by sponge
Fruit eliminates inflammable hidden danger, but the fire retardant that existing fire-proof sponge uses is contained within halogen, environment can be made after manufacture, discarding
Become pollution.
Content of the invention
The invention discloses a kind of halogen-free flameproof low resilience memory foam, environment-friendly fireproof material, product itself is with the external world
Temperature change is little, greatly improves the comfortableness of use.
Halogen-free flameproof low resilience memory foam, is made up of following raw materials by weight portion ratio:
Polyether polyol 1030 20-50 part
Polyether polyol 2000 4-10 part
MDI 23-56 part
Slow rebound polyether 8-20 part
White oil 8-20 part
Halogen-free flame retardants 9-24 part
Pore-creating agent 1.2-3 part
Amine catalyst 0.02-0.5 part
Silicone oil 0.3-0.9 part
The further improvement project of the present invention is that MDI is the MM5042 that Nanjing Chinese peaking work Materials Co., Ltd produces.
The further improvement project of the present invention is,:Described polyether polyol 1030 is produced by SKC Co., Ltd. of Korea S, polyethers
Polyhydric alcohol 2000 is made tranquil Chemical Co., Ltd. by Shanghai gold and is produced.
The further improvement project of the present invention is, the LR-00 that described slow rebound polyether produces for Mitsui Chemicals, Inc..
The further improvement project of the present invention is that described halogen-free flame retardants produces for Zhejiang Wansheng Co., Ltd.
HF560.
Compared to the prior art, the present invention has the following advantages:
The present invention adds 2000 a small amount of polyether polyol as sponge main body using 1030 polyether polyol, is equipped with MDI reaction, energy
Enough make product keep certain degree of cross linking so that product insensitive to low temperature it is ensured that winter will not be hardening, the low resilience of addition
Polyethers LR-00 has not response to temperature, makes product influenced by ambient temperature little, and during use, summer can keep feeling nice and cool, winter then can
Enough feel warm, greatly improve and low resilience effect while comfortableness, can also be improved;The halogen-free flame retardants adding has high
Fire resistance, without all kinds of harmful chemicals forbidden, using safety and environmental protection, makes sponge main body have the same of flameproof effect
When, do not affect the low resilience effect of sponge main body itself.
