Problems solved by technology

[0003] The fire hose needs to have a certain buoyancy capacity under special use conditions. At the same time, the existing fire hoses have general wear resistance and poor internal compression resistance. Therefore, it is necessary to develop an ultra-light and wear-resistant fire hose. The preparation method of the hose is to meet the needs of fire hoses with strong wear resistance, good internal compression resistance, simple preparation process and fire hoses with air flotation capacity in water

Abstract

The invention discloses a preparation method of a super-light and hard-wearing fire hose. The preparation method of the super-light and hard-wearing fire hose comprises the following steps that step 1, the preparation of an inner compression resistance layer is carried out; step 2, the preparation of a covering layer is carried out; step 3, the preparation of an inner coating layer is carried out;step 4, the preparation of a reinforcing layer is carried out; step 5, the preparation of an outer coating layer is carried out; step 6, the preparation of foam blocks is carried out; step 7, sticking of a foam layer is carried out; step 8, spraying of a hard-wearing layer is carried out; step 9, the preparation of an outer protective coating (1) is carried out; step 10, spraying of the outer protective coating (1) is carried out; and step 11, a mold is taken out, and the preparation of the fire hose is finished. The super-light and hard-wearing fire hose has high anti-pressure capacity, a super-light structure, excellent hard-wearing capacity and a noctilucent function.

Description

technical field [0001] The invention relates to a preparation process of a fire-fighting hose, in particular to a preparation method of an ultra-light and wear-resistant fire-fighting hose. Background technique [0002] A fire hose is a hose used to transport flame-retardant liquids such as high-pressure water or foam. The traditional fire hose is generally made of plastic flat yarn, synthetic fiber or yarn, linen braid, etc. according to the warp and weft. Layers of material are then lined inside the braid for waterproof performance. In addition, in order to protect the braided layer from wear and tear, some fire hoses also add an outer covering layer such as wear-resistant resin material to the outer layer of the braided layer. The outer covering layer also plays the role of pressure resistance and leakage resistance. . The lining material layer is mainly selected from materials that meet the characteristics of high pressure resistance, oil resistance, corrosion resista...
