Problems solved by technology

Therefore, there is a problem that hydrogen halide is generated when the product of polyurethane foam containing such a flame retardant is discarded and incinerated.
However, the status quo is that there has been no flame retardant comprehensively satisfactory in terms of flame retardancy, anti-fog characteristics, deformation characteristics, and scorch characteristics so far, and development of such flame retardants has been widely desired.

Embodiment

[0228] Hereinafter, the present invention is described in further detail by showing synthesis examples, reference examples, examples, and comparative examples.

Synthetic example 1

[0231] Synthesis of formula (1) compound

[0232] [chemical formula 10A]

[0233]

[0234] As a first step reaction, 312.6 g of neopentyl glycol (3.00 mol) and 109.5 g of 1,4-dioxane were filled into a tank equipped with a stirrer, a thermometer, a return line connected to a hydrochloric acid recovery unit, an absorber, 1L four-necked flask with dropping funnel and heating device. The resulting liquid was heated to 50°C. Subsequently, 460.5 g (3.00 mol) of phosphorus oxychloride was added thereto over 2 hours while maintaining the reaction temperature at 45 to 55°C. After the addition was complete, the generated hydrochloric acid was collected while the mixture was further stirred at 80° C. for 1 hour, followed by dehydrochlorination at 80° C. and a low pressure of 80 kPa for 3 hours, thereby obtaining 662.8 g of a white slurry.

[0235] 100.6 g of the above white slurry obtained in the first reaction step of Synthesis Example 1 and 214.3 g of 1,4-dioxane were charged in...

Synthetic example 2

[0237] Synthesis of formula (4) compound

[0238] [chemical formula 10B]

[0239]

[0240] According to the same method as in Synthesis Example 1 except that 15.6 g (0.26 mol) of ethylenediamine was used instead of piperidine, 71.6 g (yield 77.4%) of a solid was obtained. Phosphorus content percentage: 17.3% by weight. Nitrogen content percentage: 7.8% by weight. The obtained flame retardant compounds were used in the following Reference Examples and Examples.

Abstract

The present invention provides a polyurethane which has excellent flame retardance and various excellent performances. A phosphoroamidate compound having a specific structure is used as a flame retardant for a polyurethane foam or a polyurethane elastomer. By mixing this flame retardant with a feedstock of polyurethane resin (polyol, polyisocyanate and various additives), a polyurethane reactive feedstock composition is obtained. By reacting the polyisocyanate and active hydrogen-containing compounds such as polyol in the polyurethane reactive feedstock composition, a hardening reaction takes place and a polyurethane foam composition or polyurethane elastomer composition is obtained. The obtained polyurethane resin composition has excellent flame retardance and other excellent performances as the polyurethane foam or polyurethane elastomer.

Description

technical field [0001] The present invention relates to a polyurethane resin composition (for example, a flame-retardant polyurethane foam composition and a flame-retardant elastomer composition) excellent in flame retardancy and various properties. The invention relates to a flame retardant, a flame retardant polyurethane resin composition, a raw material composition and a reactive raw material composition thereof. In one embodiment, it relates to a raw material composition of a flame-retardant polyurethane foam. The composition contains a phosphoramidate compound having a specific structure as a flame retardant. ), deformation characteristics and scorch characteristics are comprehensively excellent. Background technique [0002] Urethane resins are mainly used in various fields of daily life products such as automotive interiors, furniture, and electrical equipment materials due to their low cost, light weight, and easy formability. As for the embodiment used, most polyu...
