The use of fire retardant coatings in electricity

Shenzhen Situjia Technology Co., Ltd. specializes in producingFire retardant coatings, and it is not uncommon for these coatings to be used in our daily life, such as high-rise buildings, high-speed railways, subways, wallpapers, etc. , Friends who do engineering in this area can find our general manager Jiang!

At present, solvent-based fire retardant coatings are better used, but because the solvents of such coatings are flammable, the construction of fire retardant coatings The fire hazard is also quite large, and the solvent has different degrees of damage to the human body. Therefore, especially in cable shafts, cable trenches, cable tunnels and other places where space is narrow or difficult to ventilate, safety protection measures should be strengthened. From the perspective of environmental protection, efforts should be made to develop water-soluble fire-retardant coatings with good adhesion to the cable sheath, good flexibility, bending resistance, non-toxicity, and good flame retardant properties.

The main directions of research work are as follows:

1. The development of film-forming materials, the development of corresponding water-based resins, and the improvement of fire-resistant coatings through the combination and modification of resins fire resistance and various physical and chemical properties.

2. Research on flame retardants, develop multi-effect, high-efficiency, low-water-soluble dehydration charring agents and foaming agents Research on the synergistic effect of a variety of flame retardants to reasonably match to improve the flame retardant effect; research on the combination of intumescent and non-intumescent fire retardant coatings, the formula contains both intumescent components and more refractory filler components, so that the The coating forms a high-strength carbonized layer with a low expansion rate under the action of a high-temperature flame; it is studied to compound organic flame retardants and inorganic flame retardants into organic-inorganic composite flame retardants under certain process conditions, giving full play to the organic and inorganic materials. advantages, eliminating the shortcomings of each.

Fire retardant coatings are widely used in the power industry, so how to use them? Water-based intumescent cable fire retardant coatings have the following characteristics:

1. It overcomes the disadvantages of high price, high toxicity, unsafe transportation, storage and use of oil-based fire retardant coatings, which is beneficial to Environmental protection and production, beneficial to the health and safety of construction workers;

3. The water-based paint does not contain halogens and other toxic components, which eliminates the toxicity caused by halogens in the paint in fires. Protects firefighters from toxicity when entering a fire;

4. Water-based paint has good decorative properties and can be formulated into various colors. It has the characteristics of decorative paint and is practical Better than solvent-based fire retardant coatings. The fire resistance of water-soluble fire retardant coatings and solvent-based fire retardant coatings is not much different, and both can meet the requirements of fire resistance. What needs to be solved is to improve their physical and chemical properties, especially flexural properties. Yuan Jinsheng studied the composition and performance of water-based cable fireproof coatings, and chose acrylic emulsion as the base material; ammonium dihydrogen phosphate, organic phosphate and ammonium polyphosphate were used as dehydration catalysts; starch, pentaerythritol and high-carbon polyhydroxyl The compound is a carbon-forming agent; ammonium polyphosphate, ammonium borate and melamine are selected as foaming agents; in order to increase the coating film!

With the rapid development of technology and economy, new talents in the industry are slowly discovering, let us work together, Make a quick and timely contribution to the fire protection cause of the motherland and the safety of people's property and life.
