Description

Mixture for fire protection boards and panels

Technical field

Fire protection cladding systems are an important part of the solution of fire parameters of building and industrial equipment.

BACKGROUND OF THE INVENTION

Nowadays, there are many fire-fighting materials on the market. These are products of pressed mineral wool treated with fire-resistant coating. They exhibit high values of thermal insulation, acoustic and fire protection properties. However, they are very bulky.

In addition, various types of fire protection boards are produced which contain, for example, expanded vermiculite or pearlite in the form of beads and an inorganic binder as fillers. They have good thermal insulation properties. However, these plates are not sufficiently strong.

A large group are also cement-fiber boards, which use Portland cement as a binder or a mixture of cement and lime, to which hydrating additives are added, wood fillers or mineral wool filler. Similarly, boards containing gypsum as a binder to which paper fibers are added. The advantage of cement-fiber and gypsum-fiber boards is their hardness, they can also be used as a building carrier material. The disadvantage is their high weight, so they cannot be used as a filler in structures or equipment where fire protection is required.

A very modern material is magnesium oxide based boards. In addition to magnesium salts, they contain glass fibers and wood chips as fillers. In addition to the non-flammability, the advantage of these boards is their strength and water resistance and the ability to reflect heat radiation, the disadvantage is the high brittleness and weight and also the low ability to reflect the heat heat.

The essence of the technical solution

Today used fire panels meet primarily the condition of non-flammability. They use standard materials, lime, cement, traditional fillers, ie mineral fibers, wood, paper. They are mostly heavy, these mixtures are not suitable as fillers for construction or industrial equipment.

The essence of the new material Mixture for fire protection panels and fillers is sodium water glass. It has excellent adhesive and bonding effects. Its heat resistance is over 1000 ° C and is perfectly heat resistant. With a pH of over 12 it has an antifungal effect. It is a purely ecological material. Once hardened, it has the form of glass, so that it is sufficiently hard, strong and water resistant, while being vapor permeable.

Glass fibers with a length of 6 to 12 mm are used as filler. It's StarStran, chopped glass fiber with silane-based lubrication. They are very heat resistant and have the ability to reflect heat radiation. At the same time, they provide excellent strength, hardness, flexibility. They are chemically resistant and at the same time they are harmless and ecological. The fibers are lightweight and thus the entire material is lightweight.

The composition has good thermal insulation properties after curing. The combination of non-flammability, thermal radiation reflection and heat-retardant capability provides the material with the ability to prevent flame-retardancy as well as protection against high-temperature ignition. The mixture is also light, elastic and solid, hard, but permeable to moisture and antifungal. It is also chemically resistant. The cured mixture can be molded at high temperature. It can also be cut very easily, eg sawing.

The mixture for fire protection panels and fillers contains 41 wt. % of glass fibers with a length of 6 to 12 mm, 58 wt. % sodium water glass, 1 wt. water glass stabilizer - hydrophilic alkoxy alkylammonium salts.
