Rubber carbon black has a strong reinforcing effect, so it can be used in rubber products to enhance the abrasion resistance and anti-slip rubber, so rubber carbon black has been widely used in rubber products, especially in the application of automobile tyres, of course, there will be a limit to the amount of everything, the rubber and the carbon black to have a good ratio, in order to play the maximum effect, not in the process of making rubber add more rubber carbon black is The better, if the amount of rubber carbon black to add too much, but will play a counterproductive effect to make its strength decline, so the question comes, in the end, how much rubber carbon black to add in the rubber in order to achieve the most satisfactory, the most perfect effect?
Rubber carbon black in the amount of rubber will directly affect the performance of vulcanised rubber, such as strength, abrasion resistance, hardness, elongation, flexural resistance, etc., there is an optimal amount of carbon black. Therefore, in the design of the formula, the reasonable choice of the amount of carbon black is very important. For example, hardness, constant tensile stress, heat generation, etc., all increase with the increase of rubber carbon black dosage, while resilience, expansion, elongation, resistivity, flexural resistance, etc., all decrease with the increase of carbon black dosage. However, the tensile strength, tear strength and abrasion resistance, etc., but with the increase in the amount of rubber carbon black and a large value. Therefore, according to the required performance, seize the main contradiction, taking into account other, reasonable selection of carbon black dosage. For example, in order to improve the abrasion resistance of the rubber material, the selection of fine particles of rubber carbon black when the dosage is less, and the selection of high structure of fine particles of rubber carbon black, the dosage can also be reduced, so that it is not because of the use of too large a quantity of lower resilience, and is conducive to maintaining a higher resistance to flex-cracking properties drink resilience, reduce heat, to ensure that in practice there is a better abrasion resistance. Generally speaking, the rubber carbon black aggregates in the rubber material began to sharply increase the interaction between the rubber carbon black with the amount of rubber carbon black with the amount of the best fit, the smaller the rubber carbon black particle size, the greater the surface activity, the higher the structure to reach the maximum tensile strength of carbon black dosage tends to reduce the amount of carbon black, usually the amount of carbon black in the 40-60 parts of the time can give the rubber products a better performance indexes. The optimal amount of carbon black, hard carbon black in about 20%-23%, soft carbon black in about 23%-26%.
