Problems solved by technology
[0003] Automobile anti-collision strip materials include natural rubber or polyvinyl chloride (PVC), but the effect is not as good as thermoplastic vulcanizate (TPV)
TPV as a car anti-collision strip material has the characteristics of low price, convenient bonding, and an aging life of more than 10 years, but the tensile strength and wear resistance of the car anti-collision strips currently on the market are not enough

[0057] The preparation method of the α, β-unsaturated carbonyl compound is:
[0058] (1) Put the weighed p-hydroxyalkylaniline in a 250mL round bottom flask, add an appropriate amount of DMF to dissolve, and cool the system to 0-5°C with an ice-water bath. While stirring, N-bromosuccinimide was added dropwise, stirred in an ice bath for 1.5-2h, then gradually returned to room temperature, and continued stirring at room temperature for 1-1.5h. After the solvent was sucked dry, it was recrystallized with chloroform and hexane to obtain 2-bromo-4-hydroxyalkylaniline. The reaction equation is as follows:
[0059]
[0060] (2) Put the weighed 2-bromo-4-hydroxyalkylaniline in a 250mL double-necked bottle, install a reflux condenser, and add an appropriate amount of toluene to dissolve. While stirring, excess aqueous formic acid was added. Then the system was heated to 110-120°C and refluxed for 4-6h. After the reaction was completed, it was cooled to room temperature, the pro...

Abstract
The invention relates to a TPV composition. The TPV composition is prepared from a vulcanized mixture through a dynamic vulcanization technology. The vulcanized mixture at least comprises the following components in parts by weight: 0.5-5 parts of alpha: beta-unsaturated carbonyl compound partly modified polymers, 0.5-5 parts of secondary amine compound modified polymers, 0.1-1 part of morpholine derivatives, 100 parts of vulcanizable elastomers and 50-200 parts of thermoplastic polyolefines, wherein an alpha: beta-unsaturated carbonyl compound contains a benzene ring, and isocyano is contained in the benzene ring; the morpholine derivatives contain sulfur elements. The invention relates to the TPV composition, and further relates to an automobile anti-collision strip using the TPV composition.
Description
technical field [0001] The invention relates to a TPV composition, and also relates to an automobile anti-collision strip material using the TPV composition. In particular, International Patent Classification number C08L53 / 00 is involved. Background technique [0002] Anti-collision strips, also known as protective strips, protective rubber strips, anti-scratch strips, straps, etc. The main function of the car anti-collision strip is to prevent the side of the car body from being scratched or bruised by foreign objects, and it plays the role of daily protection. And because the volume of the car anti-collision strip is small, it will play a certain protective role when the car body is accidentally scratched. The function of car anti-collision strips is to protect the car body from being scratched. Once the car is scratched, it is easy to damage the car paint, and even rust the parts where the paint has fallen off. The car's anti-collision strips can simply protect the car ...
