Problems solved by technology

Sponge products are easy to burn when exposed to open flames or hot flames, and the same is true for slow-rebound memory foam. Once burned, it is difficult to extinguish, and the smoke produced is also toxic to a certain extent. Fire-proof sponges are prepared by adding flame retardants It can achieve the effect of fire prevention and eliminate the hidden danger of flammability, but the flame retardant used in the existing fire prevention sponge contains halogen, which will pollute the environment after being manufactured and discarded

Embodiment 2

[0036] The halogen-free flame-retardant slow-rebound memory foam raw materials in this implementation are as follows in parts by weight:

[0037] Polyether polyol 1030 30 parts

[0038] Polyether polyol 2000 6 parts

[0039] MDI 40 copies

[0040] Slow rebound polyether 15 parts

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 [0001] The invention relates to the field of sponge preparation, in particular to a halogen-free flame-retardant slow-rebound memory sponge. Background technique [0002] Slow rebound memory foam is a kind of sponge that will not rebound immediately after being deformed by external force, but will be delayed for a few seconds and slowly restore. It has a soft hand feel, has a significant slow rebound ability, and can absorb impact, reduce vibration, and reduce The ability to release the rebound force is strong, and the cushions, pillows, mattresses and other items made of slow rebound sponge can make people feel more comfortable and natural. Sponge products are very easy to burn when encountering open flames or hot flames. The same is true for slow rebound memory sponges. Once burned, they are difficult to extinguish. The dense smoke produced is also toxic. Fire-resistant sponges are prepared with flame retardants. It can achieve the effect of fire prevention and...
