Description

[Detailed Description of the Invention] The soft urethane 7 ohm can be pasted with a koji material such as cloth, and it will look like $'-)) Tsuba-no-1! It is widely used as an automobile interior material for non-automotive items such as round clothing, bags, boots, and carpets.The pasting method can be broken by using adhesive or by heating the foam with high-frequency sea urchin in a flame. There is a method in which it is melted by β-ding and then maw-sed directly onto fabric.

The latter method, particularly the flame bonding method in which flame is used for adhesion, is advantageous in terms of equipment and economy, as it does not require a drying process and requires a moderate amount of adhesion.

The urethane foam used for frame laminate is
Various physical properties are required depending on the use. #The so-called "9 seconds" on the car seat in clothing is 1%A, that is, the pressure is 1IIl! It is necessary to have a good amount of l1iI60
, a high degree of flame retardant performance is required.

- Is Tsuyoshi flammable? When flame-retardant fabric is laminated with a frame, the composite material becomes more flammable than the fabric alone in the foam. The reason for this is that due to the 1 degree difference in combustion between the two, the temperature lasts for 9 seconds, and the original urethane foam melts and soaks into the fabric, which is the so-called "Tan-Sota phenomenon". It is thought that this will be promoted. Other foams that have a high degree of hardness are preferred, and for the preparation of Aleumranate, it is also important that the foam has a high adhesive strength with the surface material. However, the strength, elongation, hardness, and transverse properties of 8E＊＊＊＊t are maintained within 10e, and the affinity with the material to be bonded is maintained at tkII! It has been extremely difficult to achieve high adhesion strength and high flammability.

In general, esthetics μ;l & ure! The foam has good mechanical properties, can be flame laminated with ToL and L, and is also effective in making composite materials flammable, but it is expensive, expensive, and ms.
It has the disadvantage of aging easily. On the other hand, cheap Aete μllt
? The information is based on the difference in behavior such as the formation of volatilization and residue during thermal decomposition.
968, P276), it has long been the case that the more flammability that is given to a foam, which has been increasingly required in recent years, the more its adhesiveness with other materials such as fag ivy deteriorates. Research has been carried out to make this ether-based urethane foam, which is inexpensive and resistant to thermal aging, suitable for frame rolling, but it is still insufficient.

For example, as a method of making it possible to frame the VI form,
Turtle using polio (#Komei 56-4022!
), and a related point of this method is scorching due to the use of lrimer on ψo.

9. Flammability is also insufficient.

The inventors of this application have developed various mechanical properties as a result of many years of research.

Succeeded in creating a soft urethane material that has excellent thermal aging properties, has sufficient flammability, and can be used for flame lamination with the material that forms the FUMINE VM backing. The essence of this is that organic yv annate and /l ether β
is foamed and polymerized in the presence of a small amount of blowing agent, catalyst, and foam stabilizer to produce a soft XIIFI foam. A, the molecular weight of the I9ether/&/dI9O to be used is $a~2000 per hydroxyl/A/group Ill, and B, the polyether μpolyio to be mainly used is substantially 10 to 40% of the total weight of C1 gold and 19 to 100% of the weight of C1 gold and

For the first time, a reaction layer flame retardant containing 8-gev is used, D, the ψν component relative to the foam weight is excellent, and the 8-gun component is the phosphorus content in terms of chlorine. Addition WII is substantially increased to 1% with iyranate so that

Regarding the noodle strings and auxiliary agents, there are four known methods for obtaining soft urethane foam.

Generally soft 9! In order to increase the adhesive strength between the foam and the material to be bonded, it is possible to use +/% Geoμ, which has a molecular weight of 1 +/%, but the heavy use of this increases the flammability and compressibility of %fH9. Since heavy use of flame retardants can adversely affect permanent GIK and reduce adhesive strength, it is necessary to use an appropriate amount of Geo-μ, which essentially has a female flammable group in the molecule.

If rounded or used in excess, a turquoise foam will result, and the amount of compression remaining will be poor. The amount to be used is preferably 1 to 20 years in terms of total volume weight Kjt.

Examples of additive fuel agents that do not substantially react with the yyanate group include quaternary compound, organic phosphate, organic phosphate, and organic sulfonate.

．． In addition, condensed ammonium phosphates such as 0R50 (Nimmaro Ferro Organic Chemical Co., Ltd.) can also be used for IU, and can be used for Sumiryu-F P and Suden Safe PM (Sumitomo Chemical Fi'14J).

The purpose of using these additive ma*m agents is to combine them with the flame retardant in the reaction layer.The phosphorus content is ~1S% and the halogen content is 9~9% by weight based on the weight of the flame retardant. By ensuring the amount of compounding, it is thus possible to create a formulation that optimizes the phosphorus, octogen ratio, flame retardant and base.
