Description

technical field

[0001] The invention relates to traffic facilities, in particular to a rubber speed bump and a preparation method thereof. Background technique

[0002] Speed ​​bumps, also called speed bumps, are traffic facilities installed on highways to slow down passing vehicles. The shape of the speed bump is generally strip, and the material is mainly rubber. The speed bump is generally alternated with yellow and black to attract visual attention, and the road surface is slightly arched to achieve the purpose of vehicle deceleration.

[0003] The Chinese patent with publication number CN107759681A discloses a preparation method of a wear-resistant and anti-slip type speed bump material. In the preparation method of the speed bump material, the required raw materials include styrene-butadiene rubber, fluorosilicone rubber, sulfur, river sand, silane coupling agent KH-570, beet oil, river bottom sludge, pyrophyllite, broken glass, Titanate coupling agent 201, peach gu...
