Problems solved by technology

Although this application improves the airtightness of the hose, the disadvantage is that the rubber hose has three layers. If it is used for a long time in a place with high humidity in the kitchen, it is easy to peel off between layers, which will also cause gas leak problem

Abstract

The invention relates to a domestic gas rubber hose and a preparation method thereof. The rubber hose comprises the following raw materials: epichlorohydrin rubber, nitrile rubber, ceramic powder, hydrogen peroxide, sodium phthalate, carbon fibers, zinc oxide, bamboo fibers, a softening agent, ethanol, ethyl acetate, petrolatum, potassium lactate and sulfur. The preparation method comprises the steps: treating the carbon fibers and the bamboo fibers by using a small amount of ethanol; mixing the raw materials except for the softening agent and the sulfur, putting the mixture into a reaction kettle and heating to obtain a first mixture; spray-coating the softening agent and the sulfur on the inner wall of a composite rubber extruder; putting the first mixture into the rubber extruder and extruding to obtain a semi-finished product; and cooling to obtain a finished product. The rubber hose obtained by the preparation method has high flexibility, is corrosion-resistant and formed at one step, reduces the steps and saves the cost.

Description

technical field [0001] The invention relates to the field of manufacture of household gas rubber hoses, in particular to a household gas rubber hose and a preparation method thereof. Background technique [0002] Natural gas is a kind of new energy, which has little pollution to the environment and is very popular among people. Therefore, gas has become a must for people's life. At present, commercially available gas rubber hoses have good flexibility, are prone to air leakage for a long time, and are not resistant to folding. [0003] Chinese patent CN103470875A discloses a household gas rubber hose and a preparation method thereof. The rubber hose provided by this patent has a multi-layer composite structure, which can give full play to the advantages of each layer of materials, and has good air tightness, good heat resistance, good pressure resistance, good softness, small bending radius, and easy installation. Although the application improves the air tightness of the ...
