[0038] A kind of preparation method of the solvent glue that is used for SEBS base plastic runway bonding, comprises the following steps:
[0039] Step 1: Weigh 10-30 parts of thermoplastic elastomer TPE, 10-40 parts of tackifying resin, 20-30 parts of mineral spirits, and 10-20 parts of ester solvent in parts by weight, and pour them into the reaction kettle in turn as the bottom Material, control the reaction temperature at 78°C-82°C by reflux to completely dissolve it.
[0040] Step 2: React 100 parts of hydroxyl-terminated polybutadiene, 10-30 parts of isocyanate molecules, and 0.1-1.0 parts of organotin catalyst under nitrogen protection at 60°C for 6 hours to control the relationship between hydroxyl-terminated polybutadiene and isocyanate molecules. The molar ratio is 1:2-1:3 to obtain isocyanate-terminated polybutadiene.
[0041] Step 3: Weigh 20-60 parts of isocyanate-terminated polybutadiene, add it into the mixed system dissolved in Step 1, stir evenly under nitrog...

[0044] A solvent glue used for SEBS-based plastic runway bonding is prepared by the following steps:
[0045] (1) Weigh 10 parts of SEBS, 20 parts of naphthenic oil 4006, 40 parts of terpene resin, and 20 parts of butyl acetate in parts by weight, and pour them into a heating stainless steel reaction kettle in turn as a base material, through Reflux to control the reaction temperature at 80°C to make it dissolve completely and form a dissolved mixed system.
[0046] (2) Weigh 100 parts of hydroxyl-terminated polybutadiene (M n =2000), 17.4 parts of toluene diisocyanate, 0.2 parts of stannous octoate were reacted for 6 hours at 60°C under nitrogen protection, and the molar ratio of hydroxyl-terminated polybutadiene to isocyanate molecules was controlled to be 1:2 to obtain isocyanate-terminated polybutylene Diene.
[0047] (3) Weigh 30 parts of isocyanate-terminated polybutadiene, add it into the above-mentioned dissolved mixing system, stir evenly under the protection of nit...

[0050]A solvent glue used for SEBS-based plastic runway bonding is prepared by the following steps:
[0051] (1) Weigh 30 parts of SBS, 30 parts of mineral spirits, 10 parts of C5 petroleum resin, and 10 parts of butyl acetate in parts by weight, and pour them into a heating stainless steel reaction kettle in turn as a base material, controlled by reflux The reaction temperature is 80°C to make it dissolve completely to form a dissolved mixed system.
[0052] (2) Weigh 100 parts of hydroxyl-terminated polybutadiene (M n =2000), 22.2 parts of isophorone diisocyanate, 0.3 parts of stannous octoate were reacted for 6 hours at 60°C under nitrogen protection, and the molar ratio of hydroxyl-terminated polybutadiene to isocyanate molecules was controlled to be 1:2 to obtain isocyanate-blocked terminal polybutadiene.
[0053] (3) Weigh 50 parts of isocyanate-terminated polybutadiene, add it into the above-mentioned dissolved mixing system, stir evenly under the protection of nitrog...
