Abstract

The invention discloses a fiber cement firewall. The fiber cement firewall comprises the following components in parts by weight: 37-42 parts of sulfoaluminate foam cement, 8-15 parts of silicate cement, 0.7-0.9 parts of calcium stearate, 2-4 parts of lithium base curing agent, 2.7-3 parts of hydrogen peroxide, 32-42 parts of water, 10-16 parts of flame retardant, 15-20 parts of auxiliary and 8-16 parts of fiber; the flame retardant comprises the following components in percentage by weight: 23% of aluminium hydroxide, 29% of magnesium hydroxide, 29% of zinc stearate, 12% of antimony trioxide and 8% of hydrotalcite; the auxiliary comprises the following components in percentage by mass: 26% of antioxidant, 14% of perlite and 60% of coal ash; the fiber is a mixture of a quartz fiber and a magnesium oxide fiber. The fiber cement firewall is added with the flame retardant and the auxiliary, so that the flame retardant property is effectively enhanced; the fiber is adopted, so that physical properties and flame retardant property are enhanced; the adopted fiber is mixed fiber comprising a glass fiber used for enhancing the physical properties and a magnesium oxide fiber used for enhancing flame retardant property.

Description

The fibrocement fireproof brickwork

Technical field

A kind of fireproof brickwork, particularly a kind of cement fireproof brickwork.

Background technology

Along with the attention of people to the public place fire-fighting, more and more higher to the requirement of material of construction fire resistance.Domestic PLASTIC LAMINATED manufacturer selects aluminium silicate wool plate, expanded pearlite rock beam, vermiculite board as anti-fire door core board mostly, but because these quality of materials are larger, the physicalies such as intensity are poor, and fire resistance is general, reduce work-ing life, and production and use cost are too high.

Summary of the invention

For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of physical strength high, the cement fireproof brickwork that fire resistance is good.

In order to realize above-mentioned target, the present invention adopts following technical scheme:

The fibrocement fireproof brickwork, it comprises that following quality forms: sulplo-aluminate foamed cement 37-42 part, silicate cement 8-15 part, calcium stearate 0.7-0.9 part, lithium base solidifying agent 2-4 part, hydrogen peroxide 2.7-3 part, water 32-42 part, fire retardant 10-16 part, auxiliary 15-20 part, fiber 8-16 part; The weight percent component of fire retardant is: aluminium hydroxide 23%, magnesium hydroxide 29%, Zinic stearas 29%, ANTIMONY TRIOXIDE SB 203 99.8 PCT 12%, hydrotalcite 8%; The mass percent component of auxiliary is antioxidant 26%, perlite 14%, flyash 60%; Fiber is the mixture of silica fiber and magnesia fibers.

Aforesaid fibrocement fireproof brickwork, fiber are the mixture of silica fiber and magnesia fibers 2:9.

Aforesaid fibrocement fireproof brickwork, the mass percent component of magnesia fibers is: magnesium hydroxide 98%, calcium oxide 1.5%, iron 0.04%, sal epsom 0.3%, magnesium chloride 0.16%.

Aforesaid fibrocement fireproof brickwork, the length of silica fiber are 11um, and magnesian length is 45um.

Usefulness of the present invention is: the present invention has added fire retardant and auxiliary, has effectively strengthened flame retardant properties; And adopt fiber reinforcement physical property energy and flame retardant properties, the fiber of employing is blend fiber, strengthen the glass fibre of physicals and the magnesia fibers of enhancing flame retardant properties.

Embodiment

For advantage of the present invention better is described, according to the formula of fibrocement fireproof brickwork, enumerated three embodiment, the mass component of these four embodiment is as shown in table 1.

Table 1

The weight percent component of fire retardant is: aluminium hydroxide 23%, magnesium hydroxide 29%, Zinic stearas 29%, ANTIMONY TRIOXIDE SB 203 99.8 PCT 12%, hydrotalcite 8%; The mass percent component of auxiliary is antioxidant 26%, perlite 14%, flyash 60%; Fiber is the mixture of silica fiber and magnesia fibers, and fiber is the mixture of silica fiber and magnesia fibers 2:9; The mass percent component of magnesia fibers is: magnesium hydroxide 98%, calcium oxide 1.5%, iron 0.04%, sal epsom 0.3%, magnesium chloride 0.16%; The length of silica fiber is 11um, and magnesian length is 45um.

According to the component of each embodiment in table 1, the fibrocement fireproof brickwork of making, detect its performance as shown in table 2:

Table 2

As can be seen from Table 2, mechanical property and the thermal characteristics of 3 embodiment of the present invention are all fine, and tensile strength, the larger explanation stretch capability of flexural strength value are stronger; Flame retardancy of the present invention reaches B ₁Belong to difficult combustion type, flame retardant resistance reaches V ₀For highest level, the lower explanation thermal and insulating performance of thermal conductivity is better; Particularly embodiment 2 physicalies and thermal characteristics are all fine, so embodiment 2 is optimum embodiment.

Above demonstration and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
