Detailed Description
In combination with the above technical features, the main effects of the conductive composite colloid of the present invention will be clearly demonstrated in the following examples.
The conductive composite colloid of the embodiment is rubber used for a tire and is used for coating on the tire, and the working temperature of the conductive composite colloid is preferably within the allowable range of minus 80 ℃ to 220 ℃, so that the conductive composite colloid can be used even in a severe environment with extremely low temperature or extremely high temperature, and the viscoelasticity and the conductive effect of the colloid are not lost. The conductive composite colloid comprises the following components: a polymer viscoelastic material, a conductive particle and a non-conductive particle are mixed.
The conductive particles have the particle size which affects the characteristics of the colloid, so that the electrical property change is large due to external force caused by the large particle size, the smaller particle size is stable, and the tire material is mainly divided into two parts, namely a tread material and a carcass material. The matrix material needs to be a large-deflection material, and the required conductive particles need to have a large particle size (for example, a micron-sized carbon material is used); the tread material needs wear resistance, so that smaller particle size is needed to meet the performance requirement. Thus, when the conductive particles are used for grinding, particle sizes between 1 nm and 22 microns are used, and when the conductive particles are suitable for flexing, particle sizes between 20 microns and 60 microns are used. Specifically, the hardness of the conductive composite colloid is required to be between 50 and 75 shore d when used for abrasion of the tire, between 45 and 55 shore d when used for flexure of the tire, and between 45 and 60 shore d when used for a bead portion of the tire. The Shore hardness is only the test standard used in the present embodiment, but not limited thereto, and other hardness test standards, such as Shore hardness 50 approximately equal to Rockwell hardness 36.6, can be used, so that the hardness of the gel will have different data according to the test standard used.
The purpose of the non-conductive particles is to maintain the wear resistance, viscoelasticity and dry and wet grabbing performance of the rubber material and reduce the influence of the conductive particles on the physical properties of the rubber body. Wherein the formulation ratio (PHR) of the non-conductive particles is between 0.5 and 15.
In one embodiment, the conductive composite colloid is formed by mixing the base of the polymer viscoelastic material and the conductive particles in a formula ratio (PHR) of 1-150, such that the resistance of the conductive composite colloid is 104Omega to 10-1Omega is between. Wherein, the conductive particles comprise one or a combination of the following components: gold, silver, copper, memory alloy, zinc, iron, cobalt, nickel, metal foil, metal powder, metal fiber, aluminum, cesium, palladium, graphite, graphene, carbon fiber, carbon nanotube, carbon cluster or nanosphere, the composition of the non-conductive particles is selected from one or a combination of the following: quartz, silicon oxide, iodine, sulfur, phosphorus and rare earth elements.
But to be specifically noted: when the conductive composite colloid is used for measuring the physical properties of a tire, the formula ratio (PHR) of the conductive particles in the conductive composite colloid is between 2 and 110, and the resistance is between 104Omega to 10-1Omega is between. When the conductive composite colloid is used for signal transmission and power transmission of tires, the formula ratio (PHR) of the conductive particles in the conductive composite colloid is between 3 and 150, and the resistance is between 102Omega to 10-1Omega is between.
The conductive particles with different formula ratios (PHR) are added according to different purposes, so that the applicable resistance value can be achieved, and the usable viscoelasticity of the conductive composite colloid and the rubber characteristic of the use part can be still maintained. And the resistance values are respectively provided according to different electric signals transmitted, so that excessive or too little conductive particles are not added, and the rubber characteristics of the corresponding part when the conductive composite colloid is used in the tire are not influenced.
The operation, use and efficacy of the present invention will be fully understood from the description of the embodiments, which are given by way of illustration only, and the scope of the invention should not be limited thereby, and all changes and modifications that come within the spirit of the invention, including the scope of the claims and the description thereof, are deemed to be covered thereby.
