Embodiment 1～5
[0035] The formula in Table 1 is adopted to prepare the wear-resistant anti-slip rubber of the present invention, and the preparation process is as follows:
[0036] (1) Preparation of modified short fibers
[0037] Spray vinyl triethoxysilane to pretreat basalt (diameter 10-100μm, length 1-10mm), the amount of coupling agent is 1% of the mass of basalt, store and dry to make uniform modification short fibre.
[0038] (2) Mixing
[0039] 1) First mix some (50%) rough billets (natural rubber, butadiene rubber, nitrile rubber and pretreated short fibers) at a temperature of 100±5°C, and spread them on the tray after completion. 90s;
[0040] 2) Add magnesium oxide, silane, stearic acid, sulfur and ZnO to another part of rough billets (natural rubber, butadiene rubber, nitrile rubber and pretreated short fibers), add sulfur and ZnO in sequence, and then add The temperature of mixing in the material in step 1) is 125±5°C, and the time is 120s:

[0054] The electron micrograph of the rubber that embodiment 1 prepares is as figure 1 , figure 2 , image 3 with Figure 4 shown, where figure 1 The magnification of (a) is 5000, figure 1 The magnification of (b) is 15000, by figure 1 It can be seen that there are still gaps between the basalt fiber and the rubber, which belong to incomplete bonding, and the bonding form is mosaic.
[0055] in figure 2 The magnification of (a) is 6000, figure 2 The magnification of (b) is 17000, by figure 2 It can be seen that there are still gaps between the basalt fiber and the rubber, which belong to incomplete bonding, and the bonding form is electric welding.
[0056] figure 2 The electron micrograph of the welded bonded edge of basalt fiber and rubber is shown as image 3 shown, where image 3 The magnification of (a) is 5000, image 3 The magnification of (b) is 15000.

Abstract
The invention discloses wear-resistant and slip-resistant rubber and a preparation method thereof. The preparation method includes the steps of firstly, using silane coupling agent to modify short fibers to obtain modified short fibers, wherein the short fibers are at least one of carbon fibers, glass fibers and basalt fibers, and the use amount of the silane coupling agent is 0.1-1.5% of the mass of the short fibers; secondly, weighing natural rubber, cis-butadiene rubber, nitrile butadiene rubber and the modified short fibers to serve as the rough blank; mixing part of the rough blank; thirdly, adding magnesium oxide, silane, stearic acid, accelerant and active agent into the rest of rough blank, and mixing with the mixed materials obtained in the second step, wherein the accelerant and the active agent are sequentially added into the rough blank; fourthly, performing vulcanization shaping on the mixed materials obtained in the third step to obtain the wear-resistant and slip-resistant rubber. The wear-resistant and slip-resistant rubber has the advantages that an outsole made of the wear-resistant and slip-resistant rubber is good in wear resistance and slip resistance, and the wear-resistant and slip-resistant rubber is suitable for being used to produce the outsole of a tennis shoe and other outsoles with high wear resistance and slip resistance requirements.
Description
technical field [0001] The invention relates to a wear-resistant anti-skid rubber and a preparation method thereof, belonging to the technical field of rubber. Background technique [0002] At present, most of the rubber can only be used for shoe outsoles with low requirements on wear-resistant and anti-slip performance, and cannot be used for shoe outsoles with high requirements for wear-resistant and anti-slip performance, and cannot cope with complex environments such as wet slippery, oil stains, and ice surfaces Lower anti-slip requirements. [0003] Therefore, there is a need for a rubber with better wear resistance and anti-slip performance, and the shoe outsole made of it has good wear resistance and anti-slip performance, and can be suitable for use as a shoe outsole with higher requirements for wear resistance and anti-slip performance. . Contents of the invention [0004] The object of the present invention is to provide a wear-resistant anti-slip rubber and it...
