Abstract

The invention discloses an outer rubber material for a flame-retardant red fire-fighting rubber hose and a preparation process thereof. The outer rubber material for a flame-retardant red fire-fighting rubber hose includes the following components in parts by weight: 100 parts of chlorinated polyethylene CM rubber , 8-12 parts of light magnesium oxide, 20-25 parts of magnesium hydroxide, 8-11 parts of adhesive, 0.8-1.5 parts of paraffin, 1-1.5 parts of anti-aging agent, 6-10 parts of titanium dioxide, and 5 parts of sun-fast scarlet ~6 parts, benzidine yellow 0.5~1 part, flame retardant 10~15 parts, silicon dioxide 15~25 parts, reinforcing agent 35~45 parts, light calcium carbonate 30~40 parts, dioctyl ester 30~ 35 parts, 4-5 parts of vulcanizing agent and 0.8-1.2 parts of sulfur. The outer rubber material of the invention is suitable for the production of conventional steam-vulcanized rubber hoses, and the outer rubber material of the invention has moderate deformation after vulcanization, lower elongation, no under-sulfur phenomenon, and high vulcanization safety. The product made of the outer rubber material of the invention is bright in color, excellent in aging resistance, good in flame retardant effect, safe and environmentally friendly, non-toxic, can effectively prolong the service life of the rubber hose, and reduce the production cost of the rubber hose.

Description

technical field [0001] The invention relates to a rubber material, in particular to an outer rubber material for a flame-retardant red fire-fighting rubber hose and a preparation process thereof. Background technique [0002] With the improvement of people's safety awareness, the concept of fire protection has been deeply rooted in the hearts of the people, and all walks of life have targeted deployment for fire protection. Rubber hose is a hose made of rubber ingredients, which is often used for fluid transportation such as gas and liquid. The rubber hose is generally composed of an inner and outer rubber layer and a skeleton layer. The inner rubber layer directly bears the wear and erosion of the conveying medium and prevents it from leaking; the skeleton layer is the pressure-bearing layer of the rubber hose, giving the pipe body strength and rigidity; the outer rubber The layer protects the skeleton layer from external damage and erosion. Nowadays, the application fiel...
