Problems solved by technology

However, smoke detectors are mostly used in indoor environments, and can only be detected when a large amount of smoke is generated after a fire occurs for a period of time, and the alarm response time after a fire occurs is long, so it cannot be detected in time when a fire occurs, resulting in rapid spread of the fire , resulting in irreversible consequences and causing greater trouble to users

Abstract

The invention provides a warning composite material for fire detectors and a preparation method thereof, which relate to the technical field of fire detector production. The warning composite materialcomprises a conductive core and a waterproof layer wrapping the conductive core. The conductive core is made of the following raw materials by weight: 20-25 parts of polythiophene, 1-2 parts of nano-titanium dioxide, 10-15 parts of carbon black, 5-10 parts of nano-copper powder, 3-5 parts of polyvinyl chloride, 5-7 parts of vinyl acetate, 2-4 parts of ethylene propylene diene monomer, 0.8-1.2 parts of coupling agent, 1-2 parts of plasticizer and 1-2 parts of stabilizer. The waterproof layer is made of the following raw materials by weight: 30-40 parts of ethylene-tetrafluoroethylene copolymer, 10-15 parts of polyamide, 10-15 parts of acrylate and 5-10 parts of phenolic resin. The shortcomings in the prior art are overcome. The detection and warning speeds of the warning composite materialare improved, and the material is of high sensitivity. Moreover, the waterproof performance is improved, and the warning composite material has high safety and excellent overall performance and is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of fire detector production, in particular to an early warning composite material for a fire detector 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 most widely used fire detector is the smoke detector, which is a fire detector that responds to solid or liquid particles produced by combustion or pyrolysis. However, smoke detectors are mostly used in indoor environments, and can only be detecte...
