Description
Technical Field
The invention relates to the technical field of looseness prevention and sealing of screw fasteners in a non-mechanical mode, in particular to nylon glue for looseness prevention of screws.
Background
The screw is indispensable industry requisite in daily life: such as tiny screws for cameras, glasses, clocks, electronics, etc.; screws for televisions, electric appliances, musical instruments, furniture, etc.; large screws and nuts are used for engineering, buildings and bridges; transportation equipment, airplanes, electric cars, automobiles, and the like are used with screws of different sizes. The loosening of the screw is always a serious problem or even a fatal hidden danger of industrial manufacturing and industrial products, and the untimely safety accident causes unpredictable damage to the daily life, work, even transportation, national defense and military. The anti-loosening technology of threaded fasteners is one of the subjects of research in engineering industry. The early anti-loosening technology is a mechanical method such as using a cotter pin, but the use cost is high due to the requirement of high processing precision.
Compared with a mechanical method, the chemical anti-loose lock has the characteristics of low cost and high assembly efficiency, and is widely applied to the field of automobile and electronic assembly. In the prior art, chemical looseness prevention adopts the rebound of engineering resin materials such as nylon and the like, and the engineering resin materials are attached to thread surfaces through special processing, so that a bolt and a nut generate friction force by extruding the resin materials in the locking process, thereby increasing the friction force between the threads and forming resistance to impact and vibration.
Although the anti-loosening glue made of engineering resin materials such as nylon can achieve the purpose of preventing the screw from loosening, the anti-loosening glue is poor in reusability and is usually used as a one-off anti-loosening measure. When the screw needs to be screwed out and selected repeatedly, the situation that the screw cannot be screwed out occurs. Even if the anti-loosening glue can be applied again when the anti-loosening glue is required to be unscrewed and reselected every time, the use cost is increased, and meanwhile, the working strength of workers is also increased.
Therefore, how to provide an anti-loosening glue which can ensure that the screw still has good anti-loosening performance under the condition of screwing out and screwing in the screw for many times by one-time coating is a technical problem which needs to be solved by technical personnel in the field.
