Strong wear-resistance rubber sealing material for detector as well as preparation method of strong wear-resistance rubber sealing material

Abstract

The invention provides a strong wear-resistance rubber sealing material for a detector as well as a preparation method of the strong wear-resistance rubber sealing material, and relates to the technical field of detector production. The rubber sealing material is prepared from the following raw materials in parts by weight: 40 to 50 parts of ethylene propylene diene monomer, 15 to 20 parts of isoprene rubber, 10 to 15 parts of acrylic ester rubber, 6 to 10 parts of tripolybutenone sulfide, 1 to 2 parts of neopentyl glycol dioleate sulfide, 0.8 to 1.2 parts of coupling agent, 5 to 7 parts of dibenzyl disulfide, 2 to 4 parts of sulfide terpene, 4 to 6 parts of hexachlorocyclopentadiene, 6 to 8 parts of potassium triborate, 2 to 4 parts of nickelous-nickelic oxide, 4 to 6 parts of calcium fluoride, 2 to 3 parts of silicon carbon fiber, 2 to 4 parts of vulcanizing agent and 2 to 4 parts of dispersing agent. According to the strong wear-resistance rubber sealing material for the detector aswell as the preparation method thereof, the defects in the prior art are overcome; the wear resistance and the cracking resistance of the rubber sealing material can be effectively improved; influence on the normal use of the detector caused by the fact that the rubber sealing material is worn, even is cracked under the action of an external force is avoided; and the rubber sealing material has excellent overall performance and high wear resistance and is suitable for popularizing.

Description

technical field [0001] The invention relates to the technical field of detector production, in particular to a powerful wear-resistant rubber sealing material for detectors and a preparation method thereof. Background technique [0002] The fire detector is the equipment used in the automatic fire alarm system to detect the scene and find the fire. The fire detector is the "sensory organ" of the system, and its function is to monitor whether there is a fire in the environment. Once there is a fire, the characteristic physical quantities of the fire, such as temperature, smoke, gas and radiant light intensity, are converted into electrical signals, and immediately act to send an alarm signal to the fire alarm controller. [0003] The rubber sealing material is an important component of the detector, but the current formula composition and production process of the rubber sealing material are unreasonable, resulting in poor wear resistance. In this way, the rubber sealing mat...

Problems solved by technology

[0003] The rubber sealing material is an important component of the detector, but the formula composition and production process of the rubber sealing material are unreasonable at present, resulting in poor wear resistance. In this way, the rubber sealing material is easily affected by external forces during the use of the detector. Under the wear and tear or even cracking, affecting the normal use of the detector
