Embodiment Construction

[0050] The present invention will be further described below with embodiment.

[0051] The invention provides a new type of crystalline hydrate heat-insulating fire-proof coating, which can lose crystal water at a certain temperature and bring heat into the atmospheric environment by using crystal hydrate, and can also obtain crystal water at a certain temperature, thereby realizing dehydration 1. The mechanism of recyclable heat exchange process of obtaining water can produce a crystalline hydrate heat-insulating fireproof coating, which can effectively delay the fire time, reduce the flame temperature, and reduce the fire loss.

[0052] The present invention adopts the following technical scheme, a crystalline hydrate heat-insulating fireproof coating, comprising the following composition by weight percentage:

[0053] Acrylic emulsion 20-40%

[0054] Titanium dioxide 10-20%

[0055] Calcium carbonate 10-20%

[0056] Crystal Hydrate 10-30%

[0057] Cellulose 0.1-1.0%

Abstract

The invention provides crystallized hydrate heat-insulation fireproof coating, which combines noninflammability and low heat conductivity coefficient of decorative-surface coating. A preparation method is characterized by according to the principle that crystallized hydrate can lose crystallized water at a certain temperature and carry heat into atmosphere and can gain crystallized water at a certain temperature to realize circular heat exchange process by water loss and gain, preparing the crystallized hydrate heat-insulation fireproof coating for decorative surfaces. In the crystallized hydrate heat-insulation fireproof coating, crystallized hydrate can be any one of alum, magnesium sulfate heptahydrate or sodium tetraborate decahydrate or composition thereof.

Description

technical field [0001] The invention belongs to the technical field of fireproof coatings for architectural coatings. Background technique [0002] Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. The fire retardant coating is coated on the surface of the substrate. In addition to its flame retardant effect, it also has anti-rust, waterproof, anti-corrosion, wear-resistant, heat-resistant, coating toughness, colorability, adhesion, easy-drying and a certain gloss, etc. performance. [0003] Combustion is a rapid and violent oxidation reaction with flame, and the reaction is very complicated. The occurrence and progress of combustion must meet three conditions at the same time, that is, combustible substances, combustion aids (such as air, oxygen or oxidizers) and ignition s...
