The invention relates to the technical field of rubber materials, in particular to a TPE material applied to a fire hose.
Background
The fire hose is a hose used for conveying water or foam mixed liquid in fire-fighting facilities, and the traditional fire hose takes rubber as a lining, and the outer surface of the traditional fire hose is wrapped by linen. The rubber materials of the traditional lining of the fire hose mainly comprise three types, namely natural rubber, ethylene propylene rubber and polyurethane rubber, and the rubber materials generally have the defects of poor high-temperature resistance effect and easy aging and damage in a high-temperature environment.
In order to ensure that the fire hose can bear higher pressure, the rubber layer needs larger thickness, and the density of the existing rubber material is larger, so that the weight of the fire hose is greatly increased, and the fire hose is inconvenient for firemen to carry.
Disclosure of Invention
The invention aims to provide a TPE material applied to a fire hose, which has the performances of high temperature resistance, difficult aging and ultra-light weight.
In order to achieve the above purpose, the basic scheme of the invention is as follows: the TPE material applied to the fire hose comprises the following substances in percentage by mass:
further, the hydrogenated styrene-isoprene-styrene block copolymer is prepared by reacting isoprene, styrene, cyclohexane, an initiator and a catalyst by adopting an anionic polymerization technology.
Further, the hydrogenated linear hydrocarbon oil is paraffin oil.
Further, the high-temperature-resistant polypropylene comprises the following substances in percentage by mass: 65-80% of modified polypropylene, 25-35% of glass fiber, 8-10% of silane coupling agent, 1-3% of nucleating agent and 0.8-1.3% of heat stabilizer.
Further, the modified polypropylene is mainly prepared by the reaction of propylene monomers, styrene, acrylonitrile, maleic anhydride and silicon dioxide.
Further, the silane coupling agent is a vinyltriethoxysilane coupling agent.
Further, the nucleating agent consists of a benzoic acid nucleating agent and an organic nucleating agent, wherein the benzoic acid nucleating agent is sodium benzoate or aluminum benzoate; the organic nucleating agent is sodium 2, 2' -methylene methyl-bis (4, 6-di-n-butylphenol) phosphate; the weight ratio of the benzoic acid nucleating agent to the organic nucleating agent is 1: 3.
Further, the heat stabilizer is one of octyl tin maleate and butyl tin mercaptide.
Further, the polyolefin elastomer comprises the following substances in percentage by mass: 30-65% of polypropylene, 40-75% of polybutadiene with high vinyl content, 1-5% of dicumyl peroxide, 10-25% of naphthenic oil and 1-5% of phenolic antioxidant.
Further, the antioxidant is a hindered phenol antioxidant or a phosphite antioxidant.
Compared with the prior art, the scheme has the beneficial effects that:
hydrogenated styrene-isoprene-styrene block copolymer, hydrogenated straight-chain hydrocarbon oil and high-temperature-resistant polypropylene are used as main raw materials for synthesizing the TPE material, so that the TPE material has the performances of high temperature resistance, difficult aging and ultra-light weight.
Wherein the hydrogenated styrene-isoprene-styrene block copolymer is thermoplastic elastomer rubber, and the performance of the hydrogenated styrene-isoprene-styrene block copolymer is not changed at high temperature of 150 ℃ or low temperature of-60 ℃; and as a completely saturated polymer, ultraviolet rays and ozone cannot attack the polymer, molecular chains are highly branched in the hydrogenation process, the molecular weight is rapidly increased, and SEBS molecules have a mutual drag force due to the existence of the branched chains, so that the SEBS molecules cannot easily move and cannot move even at high temperature (such as 100 ℃), and the SEBS is a high-temperature-resistant polymer, namely, the SEBS is not embrittled at high temperature.
Hydrogenated straight-chain hydrocarbon oil and hydrogenated styrene-isoprene-styrene block copolymer are adopted for compatibility softening, so that the ultraviolet ray resistance and ozone resistance of the copolymer are not changed during compatibility, the high temperature resistance of the polymer after compatibility is not influenced, and the temperature range of the material is widened.
The high-temperature-resistant polypropylene material has excellent high-temperature-resistant performance, and the TPE material cannot age and be damaged under the steam of 120 ℃ in the processing process of the fire hose, so that the feasibility of the application of the TPE material in the field of fire hoses is improved; moreover, the proportion of the TPE material is only 0.89, so that the ultra-lightweight performance of the material is guaranteed, and the material is lighter than all other types of materials on the market by more than 30-60%.
