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 preparation method of a rubber deceleration belt, comprising the following steps:

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

[0046] Step 2: Put each raw material in a mixer and stir it evenly, pour it into a mold, and then put it in an extruder, and extrude it at an extrusion temperature of 170 ° C and an extrusion pressure of 20 MPa to obtain a deceleration belt material embryo. , and finally put it into a calender, extrude concave and convex patterns at an extrusion temperature of 70°C, naturally cool to room temperature, and then discharge.

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

Abstract

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

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 known as speed bumps, are traffic facilities installed on highways to slow passing vehicles. The shape of the speed bump is generally strip, and the material is mainly rubber. Speed ​​bumps are generally alternated with yellow and black to attract visual attention, and make the road slightly arch to achieve the purpose of vehicle deceleration. [0003] The Chinese Patent Publication No. CN107759681A discloses a preparation method of a wear-resistant and anti-skid type deceleration belt 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 silt, pyrophyllite, broken glass, Titanate coupling agent 201, peach gum, carbon blac...
