Abstract

The invention discloses a rubber pipe for a low pressure spraying gun. The rubber pipe comprises an inner rubber layer, a skeleton layer and an outer rubber layer which are tightly stacked in sequence from interior to exterior. When the inner rubber layer is manufactured, the components are prepared according to the corresponding parts by weight and then are placed into a banbury mixer for banbury, rubber arrangement is carried out on the condition that the rubber temperature is 165 DEG C after banbury is finished, 1.5-2.8 parts of trithiocyanuric acid and 1.2 parts of sulphur are added for mixing, and extrusion is carried out on the condition that the temperature is 350 DEG C after mixing is finished to obtain the needed inner rubber layer; when the outer rubber layer is manufactured, the components are prepared according to the corresponding parts by weight and then are placed into the banbury mixer for banbury, 2-5 parts of sulphur is added for mixing, and extrusion is carried out after mixing is finished to obtain the needed outer rubber layer. According to the rubber pipe for the low pressure spraying gun, the defects that an existing rubber pipe is complex in structure, poor in corrosion resistance, short is service life and the like can be overcome, and the rubber pipe has the advantages of being simple in structure, good in corrosion resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of rubber hoses, in particular to a rubber hose used for a low-pressure spray gun. Background technique [0002] A type of tubular rubber product used to convey gas, liquid, slurry or granular materials. It is composed of inner and outer rubber layers and a skeleton layer. The material of the skeleton layer can be cotton fiber, various synthetic fibers, carbon fiber or asbestos, steel wire, etc. Generally, the inner and outer rubber layers of rubber hoses are made of natural rubber, styrene-butadiene rubber or butadiene rubber; oil-resistant hoses are made of neoprene and nitrile rubber; acid-resistant and high-temperature resistant hoses are made of ethylene-propylene rubber, fluorine rubber or silicone rubber. [0003] There are many types of rubber hoses, and the unified naming method is based on different materials, structures, and uses. The full name of the product is: material + structure (process) + ...
