Abstract

The invention discloses a high-efficiency fire retardant for flame-retardant sparks during electric welding and a preparation method thereof. Its raw material components are calculated by weight percentage from 20% to 28% sodium silicate, 5% to 9% disodium hydrogen phosphate, 1% to 2% titanium dioxide, 0.2% to 0.6% chalk powder, 1% to 2% sodium dodecyl sulfonate and 60%~70% water. The preparation method is to mix sodium silicate with water, stir until the solid is completely dissolved, then add disodium hydrogen phosphate, stir to make it evenly mixed, add chalk powder and titanium dioxide, then add sodium dodecylsulfonate and continue stirring to make the solid completely Dissolved, and the resulting reactant was cooled to room temperature to obtain a high-efficiency flame-retardant fireproofing agent for sparks during electric welding of the present invention. The present invention has a high-efficiency fire retardant for flame-retardant sparks during electric welding, which can be used as a spray-type portable reagent. At the same time, the reagents used in this solution are basically inorganic reagents, which not only have good fire prevention effect, but also are low in price and are environmentally friendly and harmless.

Description

technical field [0001] The invention relates to a high-efficiency fire retardant for flame-retardant sparks during electric welding and a preparation method thereof. Background technique [0002] The fire protection methods generally used in the market are as follows: [0003] (1) Use fire-resistant coatings for fire prevention. This method can only be applied to fixed places such as walls, doors and windows of some buildings, and it is not easy to move; [0004] (2) Flame retardant materials are fireproof. This is a new type of high-tech product, and the price is very expensive. Not every household can afford it. fit. [0005] (3) Add flame retardant additives. This method is only suitable for adding to plastics and has relatively large limitations. Generally, chlorine and bromine are the majority, and these organic compounds have great pollution to the environment; [0006] (4) Install fire alarm system. This is a method that is more suitable for use in prosperous bui...
