Infrared Heating Processing Technology of Rubber Hose

Abstract

The invention discloses an infra-red heating processing technology for a rubber hose, which comprises the following steps: inner rubber of a product is squeezed out; the product passes through a braiding machine or a knitting machine to be wrapped with a reinforcing layer; own adhesives inside sizing materials can be activated through heating a tube blank by an infra-red heating device; the product is vulcanized after outer rubber is squeezed out, so that the inner rubber layer and the outer layer have favorable adhesive strength. According to the invention, through the adoption of the method, the conventional manner that adhesives such as toluene are sprayed on the inner rubber squeezed out is rejected, the harm of the harmful adhesives to environment and human body is avoided, and the more and more strict environment-friendly requirement at present can be met.

Description

technical field [0001] The invention relates to a new technology used in the processing of rubber hoses for automobiles, especially a new type of processing method with environmental protection. Background technique [0002] Every car has fluids such as oil, water, and gas, which need to be connected with flexible rubber hoses. Therefore, there are a lot of rubber hoses used in each car, and the rubber hoses used in the entire automobile market are very large. At present, in order to increase the adhesion of the inner and outer rubber layers and improve the fatigue resistance of the rubber hose during the processing of rubber hoses, adhesives such as toluene are sprayed between the inner and outer rubber layers. The peel strength of the inner and outer rubber layers of the mixture is very good, which meets the performance requirements of customers. However, during the processing of the product, adhesives such as toluene volatilize a large amount of harmful gases, causing a...

AI Technical Summary

Problems solved by technology

However, during the processing of the product, adhesives such as toluene volatilize a large amount of harmful gases, causing a large amount of pollution to the environment, and at the same time causing great damage to the physical and mental health of product processing personnel. Working in this environment for a long time will cause serious occupational diseases. risks of

At the same time, the adhesive remaining in the middle of the product will flow into the car along with the rubber hose, which will also bring considerable harm to the health of consumers
