Problems solved by technology

However, the results of these two techniques are not ideal
For example, the addition of large amounts of carbon black to rubber compositions generally results in a high degree of hysteresis loss, so the use of such compounds in tires can result in excessive heat build-up and poor tear resistance
As another example, adding a large amount of sulfur to a rubber composition generally results in poor aging resistance of the formulation, and moreover, simply increasing the degree of vulcanization to achieve high modulus is often very impractical

Abstract

The invention relates to a nano additive as well as a preparation method and application thereof. The chemical structural formula of the nano additive is as shown in the specification, in the formula,n is an oxidation state of a metal element M; n is 2, 3 or 4; Alk is a hydrogen atom or a fat chain, alicyclic hydrocarbon or aromatic compound of which the carbon atom number is 1-18; x is greater than or equal to 0; y is greater than 0; an F-group is a short chain with functional groups, specifically a fat chain, alicyclic hydrocarbon or aromatic compound of which the carbon atom number is 2-50. Compared with the prior art, the nano additive provided by the invention is capable of increasing the elastic modus of a rubber composition when being used for preparing rubber, and in a part of demonstrative application schemes, rubber compositions with the nano additive are very high in slippery sliding resistance, and mostly have increased elastic modus and elongation at break.

Description

technical field [0001] The invention relates to the field of tire nano-additives, in particular to a nano-nano additive and its preparation and application. Background technique [0002] It is desirable in the tire industry to increase the modulus of compounds used in base tread compositions and tire wire cover compounds. In order to increase the modulus of the above rubber compounds, it is common practice to add a large amount of reinforcing fillers, such as carbon black and silica, to these rubber compounds, or to increase the degree of vulcanization of these rubber compounds. However, the results produced by these two techniques are not ideal. For example, the addition of large amounts of carbon black to rubber compositions generally results in a high degree of hysteresis loss, and thus the use of such compounds in tires results in excessive heat build-up and poor tear resistance. As another example, adding a large amount of sulfur to a rubber composition generally resu...
