44 by have formula (I) phosphonate be converted into the present invention fire retardants spend time amounts will depend on it is a variety of because
Element and change, these factors include, for example, the chemical constitution of starting phosphonate, the temperature of reaction, others reaction condition etc..
For example, higher temperature can cause the faster reaction time.It is believed that producing water and a kind of water absorbing agent in the course of reaction
Or the presence of vacuum can also reduce the reaction time.The design of reactor, in heating process presence of other materials etc. also
The time of reaction can be influenceed.
45 by one kind often at for example, at least 200 DEG C, 220 DEG C, 250 DEG C or higher of temperature by having formula (I)
The time that phosphonate is heated 20 hours or less, is typically less than 12 hours obtains good conversion.In some cases, should
Time can be very short, such as using higher temperature, such as 250 DEG C to 400 DEG C or the temperature more than 400 DEG C, one
The reaction time can be greatly reduced to for example, small in the reactor or environment for causing heat efficiently to pass to the parent material by planting
It is possible in 0.2 hour, 0.1 hour or 0.01 hour or less, and with the complete reaction time of second or smaller measurement
's.
46 generally, to the fire retardant of the present invention complete conversion be by a temperature of from 200 DEG C to 400 DEG C by this
The heating of beginning phosphonate is obtained from 0.01 or 0.2 to 20 hour, from 0.1 or 0.2 to 12 hour or from 1 to 8 hour, but such as
The amount of time discussed above for converting completely will depend on the temperature.For example, being heated at from 250 DEG C to 400 DEG C
Phosphonate with formula (I) will need the heating less than 12 (such as from 1 to 8) hours.When the starting phosphonate from 260 DEG C to
Heated 1 to 6 hour at 340 DEG C, such as at 2 to 6 hours, have been obtained for excellent result.
47 for example, by three-[methylphosphonic acid] aluminium salts, i.e. one kind has water-soluble solid compound (the wherein R of formula (III)
Methyl), from heating at a temperature of 250 to 320 DEG C 2 to 6 hours to form a kind of solid material, i.e. compared to starting material
Material, it is insoluble in water and stable at a temperature of more than 400 DEG C.Higher reaction temperature can be used, however, such as at this
Seen in a little examples, heated at 280 DEG C 4 hours and produce excellent result.
Similarly, three-[ethylphosphonic acid] aluminium salts are heated, i.e. the compound wherein R with formula (III) is ethyl, or
Three-[phenyl-phosphonic acid] aluminium salts, i.e. the compound wherein R with formula (III) is phenyl, cause to include class at similar conditions
Like ethyl and the fire proofing of phenyl.
48 generally, the mixture independent heating of selected phosphonic acid metal salt or salt as parent material, i.e. be not present
Other materials.However, people can be such as a kind of inert carrier, another fire retardant or other possible additives
These salt are heated Deng in the presence of, although the presence of water of addition is typically avoided by, as it is believed that during the course of the reaction water from this
It is eliminated in parent material.For example, can be by these parent materials and other fire proofings, poly- before heating is more than 200 DEG C
Polymer stabilizer or the mixing of other known polymeric additive.The thermal transition of these salt can also be in a kind of a small amount of polymerization
Thing occurs as in the presence of inert carrier, however, people must be careful to avoid the conversion of the wherein starting salt by other materials
There is a situation where hindered.For example, a kind of polymer or other materials can at the reaction temperatures melt and coat the salt,
Or even with the reactant salt, so as to produce undesirable result.
50 in many embodiments, and compound of the one kind with formula (I) is heat-treated in the absence of experience under other components.Such as
There are a kind of polymer or other inert carriers in fruit, it exists with the amount of the amount less than phosphonic acid metal salt in the course of reaction,
For example, the combination of phosphonic acid metal salt and polymer by weight is less than 50% or less than 25%, typically it is less than by weight
10%, it is, for example, less than 5% or from 0 to 2%.Due to having the salt of formula (I) to be considered as discharging water in the reaction, it may be desirable to keep away
Exempt to heat the salt in the presence of following material more than 200 DEG C, the material is unstable at high temperature in the presence of water, including can
Undergo the material of the polymer of hydrolysis.
51 according to the present invention, the phosphonic acid metal salt with formula (I) its be incorporated in its protection polymer body it
Before be thermally transformed by the reproducing beam as a kind of different, more thermally stable fire proofings.With salt (it is also referred to as fire retardant) phase with formula (I)
Instead, this fire retardant is stable under the processing temperature more than 200 DEG C and do not suffer from may be for such as polymer (such as polyester
And polyamide) reaction that has adverse effect, these polymer include be easy to react and be broken bonded.
52 for example, poly- phthalic acid alkylene ester, polyamide and a lot of other condensation polymers are processed at high temperature.
At high temperature, the salt experience with formula (I) substantially discharges the reaction of water, and this can cause the hydrolysis in the case where ester or acid amides are bonded
(hydolysis),
53 so as to the loss for causing chain rupture and molecular weight and desired physical characteristic.In comparison example 1, tasted
Try a kind of salt with formula (I) being combined into a kind of polyamide of glass-filled at elevated temperatures, so as to cause polymerization
Thing is degraded.Although whether being responsible for observed degraded being not in the elimination of the heat treatment process reclaimed water of the salt with formula (I)
Know, the fire retardant of the invention from example 1,2 and 3 is successfully bound in the polyamide of identical glass-filled,
Without obvious degraded.
