Long-acting anti-freezing flame-retardant additive for water and preparation method thereof

Abstract

The invention belongs to the technical field of anti-freezing agent additives, and particularly relates to a long-acting anti-freezing flame-retardant additive for water and a preparation method thereof. The long-acting anti-freezing flame-retardant additive for water is composed of a material A and a material B, wherein the material A is in a solid state, and the material B is in a liquid state; the material A is prepared from 86.4 g to 87.8 g of an anti-freezing agent and 12.2 g to 13.6 g of urea in every 100 g of the material A; and the material B is prepared from 24.5 g of a corrosion inhibitor, 1.26 g of a bactericide and 74.24 g of deionized water in every 100 g of the material B. After the long-acting anti-freezing flame-retardant additive is added, the freezing point of a water body is greatly reduced, the corrosion is low, the flame retardance is good, and the biotoxicity is small, so that the reduction value (as low as -55 DEG C) of a salt anti-freezing agent on the freezing point of the water is further reduced, the defect that the metal corrosion inhibition effect of a conventional anti-freezing additive for water is gradually reduced along with the use time is overcome, and the corrosion effect of salt components in a conventional anti-freezing agent on a metal component under a dry-wet alternating environment condition is innovatively reduced.

Description

Technical field [0001] The present invention belongs to the technical field of antifreeze additive, and more particularly to water for long-term anti-freeze flame retardant additives and preparation methods thereof. Background technique [0002] Water antifreeze additives are widely used. The effective antifreeze ingredients can reduce salt and alcohols of water ice points after dissolving, and then prepared by metal corrosion inhibitor, fungicides and other components. Both salt water antifreeze additives and alcohol water antifreeze additives can have a good antifreeze effect on the water body, but there is a great difference in material cost and use scenarios. In a water body that does not contain alcohol ingredients (fire-fighting water, some industrial circulation water, special storage materials, etc.), the salt water antifreeze additive has better applicability, and its main component is saline antifreeze and water. Not only is good, but also has good flame retardant. Howe...

Problems solved by technology

However, if most of the antifreeze additives for salt water on the market are added to the metal pipeline system for a long time, the effect of the antifreeze additive will be weakened due to changes in the pH value of the water quality, etc., and antifreeze additives or original metal corrosion inhibitors need to be added regularly to ensure the use. Effect, to avoid corrosion of metal pipe wall, box body or pool body, swelling and corrosion of rubber sealing ring of pipe fittings, and turbidity of water body, etc.

Moreover, once the pipeline leaks, under the condition of alternating dry and wet and aerobic conditions, due to electrochemical corrosion, metal pipelines and facility surfaces added with conventional salt water antifreeze are more likely to corrode when salt water leaks
