Problems solved by technology

[0005] Existing fire hydrants are all made of metal, and cast iron is the most popular. Cast iron is very easy to rust, especially outdoors, which has buried hidden dangers for fire fighting. If the maintenance and replacement are not timely, it will be difficult to open the fire hydrant at the fire site due to rust. Even the phenomenon of not being able to open is unavoidable

Embodiment 1

[0027] Raw materials: 100 parts of thermoplastic phenolic resin, 43 parts of fire retardant, 5 parts of short glass fiber (purchased from Taian Xianghe Composite Material Co., Ltd., length 3 mm) treated with coupling agent KH-560, curing agent hexamethylene tetra 5 parts of amine, 11 parts of silicon dioxide (2000 mesh) and 12 parts of titanium dioxide as reinforcing agent. The release agent is chlorinated paraffin 50#.

[0028] Fire retardant formula (parts by mass): 6 colloidal antimony pentoxide, 8 decabromodiphenylethane, 7 aluminum dihydrogen phosphate, 5 potassium silicate, 10 hydrotalcite, and 7 ammonium molybdate.

[0029] Preparation:

[0030] (1) First put the fireproofing agent, glass short fiber, curing agent, and reinforcing agent in a high-speed mixer, and stir for 20 minutes to fully disperse and evenly;

[0031] (2) Heat the phenolic resin to 100°C until the material is in a molten state, add the material obtained in (1) and stir evenly, place it on an open m...

Abstract

The invention discloses a phenolic resin fire hydrant which is prepared from the following components in parts by mass in a mold pressing manner: 100 parts of phenolic resin, 42-57 parts of a fire retardant, 5-7 parts of glass fiber, 5-8 parts of a curing agent and 10-30 parts of a reinforcing agent. The phenolic resin fire hydrant disclosed by the invention has the advantages that the phenolic resin fire hydrant cannot be combusted in fire, does not rust forever, does not need to be maintained or replaced at regular time, is not inferior to a metal material in pressure resistance, and is flexible, easy and rapid to power on/off, light in weight, low in price, simple in production process, easy in obtaining materials, and applicable to market popularization.

Description

technical field [0001] The invention belongs to the field of fire-fighting equipment, and in particular relates to fire-fighting equipment based on polymer materials and a preparation method thereof. Background technique [0002] A fire hydrant is a fixed fire-fighting facility, also known as a fire hydrant. Its main function is to supply fire trucks with water from the municipal water supply network or outdoor fire-fighting water supply network to put out fires. Isolate the combustion aid and eliminate the source of ignition. There are indoor fire hydrants and outdoor fire hydrants. The indoor and outdoor fire hydrant system is one of the important fire-fighting facilities for fighting fires. [0003] According to the fire hydrant setting method, it can be divided into: 1. Indoor fire hydrant: (divided into ordinary type and decompression type) connected to fire hose and water gun; 2. Outdoor fire hydrant: connected to fire truck water supply or fire hose and water gun to...
