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

Embodiment Construction

[0010] Refer to the attached figure, the infrared heating process of the rubber hose, adding adhesive to the compounded rubber of the inner and outer rubber layers of the rubber hose 1, the inner diameter of the rubber hose 1 is φ3.5mm-φ50mm, and the inner rubber of the rubber hose 1 The layer is extruded through a braiding machine or a knitting machine to coat the tube blank with a reinforcing layer, and then heat treatment by an infrared heating device, and the temperature rises to activate the adhesive in the rubber compound. The infrared heating device is composed of 12 electric heating tubes 2 and power control unit 3. Products of different specifications have different speeds through the infrared heating device. The speed of products with different pipe diameters passing through the infrared heating device can be adjusted to 5m / min~10m / min, and then adjust the heating tube speed. Power, the heating power is controlled at 65% to 70%, the heating temperature is controlled a...

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...
