Problems solved by technology

[0004] However, after the speed bump made of this speed bump material is laid on the road, the speed bump is under the harsh environment of being soaked in water and exposed to the sun, which leads to a faster aging process of the speed bump and a shorter service life of the speed bump, which needs to be improved

preparation example Construction

[0044] A method for preparing a rubber speed bump, comprising the steps of:

[0045] Step 1: According to parts by weight, weigh styrene-butadiene rubber, sulfur, vulcanization accelerator, zinc oxide, stearic acid, calcium carbonate, white carbon black, modified 2,2'-thiobis(4-methyl-6 -tert-butylphenol), 2-mercaptobenzimidazole, microcrystalline wax, UV absorber, softener, dispersant, plasticizer;

[0046] Step 2: Put all the raw materials in a mixer and stir them evenly, then pour them into the mold, then put them in the extruder, and extrude them at an extrusion temperature of 170°C and an extrusion pressure of 20MPa to obtain the green body of the speed bump material , and finally put it into a calender, press out the concave-convex pattern at an extrusion temperature of 70°C, cool naturally to room temperature, and then discharge.

[0047] The preparation method of the modified 2,2'-thiobis(4-methyl-6-tert-butylphenol) is described in detail below.

Abstract

The invention discloses a rubber speed bump and a preparation method thereof. The rubber speed bump is made of the following raw materials in parts by weight: styrene-butadiene rubber 10-15 parts sulfur 0.5-1.5 parts vulcanization accelerator 0.3-1.5 parts zinc oxide 0.5-1 parts stearic acid 1-2 parts calcium carbonate 45- 55 parts of white carbon black 5-15 parts of modified 2,2´-thiobis(4-methyl-6-tert-butylphenol) 0.1-0.5 parts of 2-mercaptobenzimidazole 0.1-0.5 parts of microcrystalline wax 0.3 ‑0.5 part UV absorber 0.1‑0.3 part softener 0.3‑0.5 part dispersant 1‑5 part plasticizer 0.5‑1 part. The beneficial effects of the invention are: the rubber speed bump has good aging resistance, thereby prolonging the service life of the speed bump.

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...
