Process of anti-collision safety airbag barrel formed through EVA rubber material

Abstract

The invention discloses a process of an anti-collision safety airbag barrel formed through an EVA rubber material. The process comprises the following steps of S1, material mixing and forming, wherein an EVA raw material is added into an internal mixer to be mixed, then a filler, a cross-linking agent, a foaming agent and a foaming promoter are added for mixing, the mixing time ranges from 20 min to 25 min, discharging is carried out after uniform mixing, and an EVA rubber composite material is obtained; S2, EVA rubber granulating; S3, molding and shaping of an injection molding machine; S4, passing of a constant-temperature box; S5, trimming; S6, quality inspection; and S7, packaging and delivery. The anti-collision safety airbag barrel is mainly composed of EVA, the EVA is a novel environment-friendly foaming material, has the advantages of good buffering, shock resistance, heat insulation, moisture prevention, chemical corrosion resistance and the like, is non-toxic, does not absorb water and can be recycled, and therefore greater environment friendliness is achieved; and the anti-collision safety airbag barrel is simple and reasonable in structural design, low in use and maintenance cost and free of environment pollution, and the production process of the anti-collision safety airbag barrel is relatively simple, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of an anti-collision airbag barrel, in particular to a technology of an anti-collision airbag barrel formed of EVA rubber material. Background technique [0002] With the gradual improvement of vehicle performance, the increase of car ownership year by year, the improvement of road surface roughness and the uneven driving skills of drivers, traffic accidents often occur. Especially at the turning point of the road, the entrance and exit of the upper and lower bridges, the entrance and exit of the toll station, and the slope guardrail, etc., the traffic accident rate has increased significantly in recent years. According to the requirements of relevant regulations, higher requirements are put forward for the performance of traffic safety. At the same time It is also proposed that in places where traffic collision accidents are more likely to occur, special warning anti-collision facilities, such as anti-colli...

Problems solved by technology

[0003] The anti-collision airbag barrel is a kind of road facility, which is mainly used for better cushioning when the vehicle is accidentally hit by the road surface, so as to protect the safety of the vehicle, passengers and road facilities; at present, the existing anti-collision airbag barrel Most of them are made of plastic. Plastic is a kind of hard-to-degrade material, which can exist for decades to hundreds of years, resulting in poor environmental protection of the airbag barrel, and the anti-collision airbag barrel made of plastic is easy to be damaged during impact. As a result, the reliability of its use is reduced, and the production process of the anti-collision airbag barrel is relatively complicated, and the production cost is high. Therefore, we propose a technology of anti-collision airbag barrel formed of EVA rubber material
