New magnetofluid tire seal material taking ethyl silicon oil as continuous phase

Abstract

The invention discloses a new magnetofluid tire seal material taking ethyl silicon oil as continuous phase, belonging to the technical field of tires. The formula of the new magnetofluid tire seal material is characterized by comprising the ethyl silicon oil, titanium dioxide, nanoscale ferroferric oxide powder, nanoscale Fe-Si-Al magnetic powder core micro-powder, N, N-dimethyl amino-propylamine, OP-10, petroleum sodium sulfonate, butadiene rubber particles and liquid polysulfide rubber. The new magnetofluid tire seal material taking the ethyl silicon oil as the continuous phase is mainly applied to a radial tire with a steel wire curtain layer, does not influence the dynamic balance of a wheel, is capable of rapidly self-repairing a nick (with the diameter less than or equal to 10mm), is not dried-up and frozen, and is high in reliability, good in stability and durable in use. After the new magnetofluid tire seal material is used, a circle of magnetofluid is evenly attached to the inner wall of the tire along with the rotation of the wheel; the magnetofluid is stably and evenly attached to the inner wall of the tire for a long time under the attraction of the steel wire curtain layer in the tire, so that the dynamic balance of the wheel is not influenced; compared with the prior art, the new magnetofluid tire seal material taking the ethyl silicon oil as the continuous phase is a revolutionary improvement indeed.

Description

technical field [0001] The invention belongs to the technical field of tires. The invention relates to a new self-replenishing material applied to radial tire sealing, in particular to a new magnetic fluid tire sealing material with ethyl silicone oil as the continuous phase. Background technique [0002] Automobiles and various motor vehicles have become one of the important symbols of modern civilization. During their use, tires are punctured by nails or sharp hard substances on the road surface to cause deflation, which often causes the vehicle to fail to operate normally. The earliest automatic tire sealant was applied in the US military wheeled vehicles in the 1920s and 1930s. The tires of military vehicles were filled with automatic tire sealant. It has a history of 80-90 years. The advantage of the automatic tire repair fluid in the prior art is that it can be repaired in 3 seconds without removing the tire; however, it also has many disadvantages: 1. It affects the d...

Problems solved by technology

The advantage of the automatic tire repair fluid in the prior art is that it can be repaired in 3 seconds without removing the tire; however, it also has many disadvantages: 1. It affects the dynamic balance of the wheel: when a can of automatic tire repair is used After the liquid is removed, 200ml-300ml of liquid remains on the inner bottom of the tire. This liquid makes the wheel run like an eccentric wheel, which not only increases the noise, but also reduces the stability, thus affecting the dynamic balance and belt when the wheel is running. There is a certain degree of traffic safety hazard

2. When the diameter of the tire wound is greater than 6mm, the automatic tire sealant does not work

3. There are also some inflatable tank type automatic tire sealant products, the ingredients of which can only temporarily inflate the flat tire and reduce leakage, until the vehicle is driven to the nearest repair station

4. Some tire sealant products will dry up inside the tire or freeze in cold weather, not only lose the sealing effect, but will damage the inner wall of the tire
