The invention has the following beneficial effects:

(2) As can be seen from the data of the example 1 and the comparative examples 1 to 4, the benzyldecabromodiphenylethane, the antimony trioxide and the zinc borate play a synergistic role in preparing the high-performance SBS modified asphalt waterproof coiled material, and the flame retardant property of the SBS modified asphalt in the SBS modified asphalt waterproof coiled material is synergistically improved; this is:
the decabromodiphenylethane absorbs heat in the combustion process to generate HBr, the HBr density is higher than that of air, the oxygen concentration near the combustible is reduced by covering the surface of the combustible, and a certain flame retardant effect is achieved. Meanwhile, HBr is easy to react with free radicals such as HO, O and the like generated by polymer combustion to generate water and Br free radicals, so that the activity of the combustion reaction is reduced. After the decabromodiphenylethane and the antimony trioxide are compounded, the antimony trioxide can effectively capture Br & lt- & gt in the reaction, and the decabromodiphenylethane is promoted to absorb heat to generate HBr, so that HO & lt- & gt, O & lt- & gt free radicals generated by the combustion reaction can be better absorbed. At the same time, antimony trioxide captures Br and radicals form SbBr3Or SbBrO, which can continue to decompose to SbBr over a wide temperature range3。SbBr3The density is higher than HBr, and the coating can better cover inflammable matters, thereby achieving the effect of further flame retardance. When the temperature is higher than 300 ℃, the zinc borate is thermally decomposed to release crystal water, and the effects of absorbing heat and cooling and diluting oxygen in air are achieved. On the other hand, zinc borate decomposes at high temperatures to form B2O3Simultaneously reacts with Br in decabromodiphenylethane to generate ZnBr2The coating layer is formed on the surface of the inflammable substance, and can suppress the generation of inflammable gas and prevent oxidation reaction and thermal decomposition. In addition, zinc borate reacts with decabromodiphenylethane during combustion to produce BBr3，BBr3HBr is generated by the action of water in gas phase, and Br-free radicals are generated in flame, and the free Br-free radicals can prevent the chain reaction of hydroxyl free radicals, thereby playing a role of flame retardance.
(3) As can be seen from the data of comparative examples 6-8, the weight ratio of decabromodiphenylethane, antimony trioxide, zinc borate is different from (1-2): (0.3-0.6): (0.3-0.6), the oxygen index of the prepared SBS modified asphalt waterproof coiled material is greatly different from that of the examples 1-4 and is far smaller than that of the examples 1-4. The invention relates to decabromodiphenylethane, antimony trioxide and zinc borateThe reinforcing system, in examples 1-4, when preparing the high-performance SBS modified asphalt waterproof coiled material, is controlled by adding decabromodiphenylethane, antimony trioxide and zinc borate according to the weight ratio of (1-2): (0.3-0.6): (0.4-0.7) to realize that HBr and Br & free radical are generated by heat absorption in the combustion process of decabromodiphenylethane in a reinforcing system to reduce the activity of combustion reaction; antimony trioxide captures Br-free radical to generate SbBr3Or SbBrO is further flame retardant; reacting zinc borate with Br free radical to generate ZnBr2The flame-retardant modified asphalt waterproof coiled material has the characteristics of adhesion to the surface of a combustible substance and the like, so that a reinforcing system consisting of decabromodiphenylethane, antimony trioxide and zinc borate is added into the high-performance SBS modified asphalt waterproof coiled material to improve the flame retardant property of the high-performance SBS modified asphalt waterproof coiled material.

The flame retardant property test of the SBS modified asphalt waterproof coiled materials prepared in the examples 1-4 and the comparative examples 1-8 shows that:
Figure RE-GDA0002619494640000121
Figure RE-GDA0002619494640000131
from the above table, it can be seen that: (1) as can be seen from the data of examples 1-4 and comparative example 5, the oxidation index (i.e. flame retardant property) of the high-performance SBS modified asphalt waterproof coiled material prepared in examples 1-4 is significantly higher than that of the SBS modified asphalt waterproof coiled material prepared in comparative example 5; meanwhile, as can be seen from the data of examples 1 to 4, example 4 is the most preferred example.
(2) As can be seen from the data of the example 1 and the comparative examples 1 to 4, the benzyldecabromodiphenylethane, the antimony trioxide and the zinc borate play a synergistic role in preparing the high-performance SBS modified asphalt waterproof coiled material, and the flame retardant property of the SBS modified asphalt in the SBS modified asphalt waterproof coiled material is synergistically improved; this is:
the decabromodiphenylethane absorbs heat in the combustion process to generate HBr, the HBr density is higher than that of air, the oxygen concentration near the combustible is reduced by covering the surface of the combustible, and a certain flame retardant effect is achieved. Meanwhile, HBr is easy to react with free radicals such as HO, O and the like generated by polymer combustion to generate water and Br free radicals, so that the activity of the combustion reaction is reduced. After the decabromodiphenylethane and the antimony trioxide are compounded, the antimony trioxide can effectively capture Br & lt- & gt in the reaction, and the decabromodiphenylethane is promoted to absorb heat to generate HBr, so that HO & lt- & gt, O & lt- & gt free radicals generated by the combustion reaction can be better absorbed. At the same time, antimony trioxide captures Br and radicals form SbBr3Or SbBrO, which can continue to decompose to SbBr over a wide temperature range3。SbBr3The density is higher than HBr, and the coating can better cover inflammable matters, thereby achieving the effect of further flame retardance. When the temperature is higher than 300 ℃, the zinc borate is thermally decomposed to release crystal water, and the effects of absorbing heat and cooling and diluting oxygen in air are achieved. On the other hand, zinc borate decomposes at high temperatures to form B2O3Simultaneously reacts with Br in decabromodiphenylethane to generate ZnBr2The coating layer is formed on the surface of the inflammable substance, and can suppress the generation of inflammable gas and prevent oxidation reaction and thermal decomposition. In addition, zinc borate reacts with decabromodiphenylethane during combustion to produce BBr3，BBr3HBr is generated by the action of water in gas phase, and Br-free radicals are generated in flame, and the free Br-free radicals can prevent the chain reaction of hydroxyl free radicals, thereby playing a role of flame retardance.
(3) As can be seen from the data of comparative examples 6-8, the weight ratio of decabromodiphenylethane, antimony trioxide, zinc borate is different from (1-2): (0.3-0.6): (0.3-0.6), the oxygen index of the prepared SBS modified asphalt waterproof coiled material is greatly different from that of the examples 1-4 and is far smaller than that of the examples 1-4. The invention discloses a preparation method of a high-performance SBS modified asphalt waterproof coiled material, which comprises the following steps of taking decabromodiphenylethane, antimony trioxide and zinc borate as reinforcing systems, and adding decabromodiphenylethane, antimony trioxide and zinc borate in a weight ratio of (1-2): (0.3-0.6): (0.3-0.6) to realize that HBr and Br are generated by absorbing heat in the combustion process of decabromodiphenylethane in a reinforcing system to reduce the activity of combustion reaction; antimony trioxide captures Br-free radical to generate SbBr3Or SbBrO is further flame retardant; reacting zinc borate with Br free radical to generate ZnBr2The flame-retardant modified asphalt waterproof coiled material has the characteristics of adhesion to the surface of a combustible substance and the like, so that a reinforcing system consisting of decabromodiphenylethane, antimony trioxide and zinc borate is added into the high-performance SBS modified asphalt waterproof coiled material to improve the flame retardant property of the high-performance SBS modified asphalt waterproof coiled material.
The above description should not be taken as limiting the invention to the embodiments, but rather, as will be apparent to those skilled in the art to which the invention pertains, numerous simplifications or substitutions may be made without departing from the spirit of the invention, which shall be deemed to fall within the scope of the invention as defined by the claims appended hereto.
