Problems solved by technology

This kind of method is complicated, and most of them only stay in the stage of scientific research
3. The method of coating particles with thermosetting flame retardant resin, but the cost of this method is relatively high
Similarly, most of the materials are inorganic materials, and it is difficult to meet the expectations of light fireproof materials. In addition, the thermal conductivity is relatively high and the bulk density is large, which brings certain difficulties to the construction.

example 1

[0045] The ordinary grade E-303 expandable polystyrene particles were pre-expanded for 30 minutes under a steam pressure of 0.05 MPa to obtain polystyrene beads with a particle diameter of 4-6 mm, counting as 50 parts.

[0046] Mix 40 parts of 40% concentration silica sol, 7 parts of 3000mPa·s phenolic resin, 3 parts of microencapsulated red phosphorus flame retardant, stir well with the additives, and pour them together with 50 parts of pre-released polystyrene beads Mix with a mixer and coat evenly, then put it in a 70°C oven for 20 minutes and take it out.

[0047] The cured film-coated beads were molded under 0.15MPa steam pressure for 10 minutes, and cut to obtain a "pomegranate" fireproof insulation board. The obtained insulation board did not drip when burned, and the limiting oxygen index was 24.8%.

example 2

[0049] The ordinary grade E-501 expandable polystyrene particles were pre-expanded for 18 minutes under the steam pressure of 0.2 MPa to obtain polystyrene beads with a particle diameter of 3-5 mm, counting as 65 parts.

[0050] Mix modulus 2.8, 10 parts of sodium silicate with a concentration of 15%, 20 parts of 2000mPa·s phenolic resin, 2 parts of aluminum hydroxide flame retardant, 3 parts of expandable graphite flame retardant, and mix well with additives, and mix with 65 Pour the pre-issued polystyrene beads into the mixer to mix and coat evenly, and then put them in an oven at 105°C for 7 minutes and take them out.

[0051] The cured film-coated beads were molded under 0.1MPa steam pressure for 20 minutes, and cut to obtain a "pomegranate" fireproof insulation board. The obtained insulation board did not drip when burned, and the limiting oxygen index was 26.2%.

example 3

[0053] The flame-retardant grade F-302 expandable polystyrene particles were pre-expanded under 0.35 MPa steam pressure for 8 minutes to obtain polystyrene beads with a particle size of 2-4 mm, which was counted as 45 parts.

[0054] Mix modulus 3.1, 20 parts of potassium silicate with a concentration of 25%, 20 parts of silica sol with a concentration of 30%, 5 parts of 1000mPa·s urea-formaldehyde resin, 5 parts of magnesium hydroxide flame retardant, 5 parts of phosphate ester flame retardant, and auxiliary After the agent is fully stirred evenly, pour it into the mixer together with 45 parts of pre-released polystyrene beads to mix and coat evenly, and then put it in a 90°C oven for 15 minutes and take it out.

[0055] The cured film-coated beads were molded under 0.35MPa steam pressure for 12 minutes, and then cut to obtain a "pomegranate" fireproof insulation board. The obtained insulation board did not drip when burned, and the limiting oxygen index was 22.7%.

Abstract

The invention relates to a "pomegranate-type" fireproof thermal insulation plate. The "pomegranate-type" fireproof thermal insulation plate is a fireproof thermal insulation plate having a structure similar to pomegranate, and is prepared by subjecting each polystyrene particle monomer to composite treatment to form a structure of pomegranate seeds. The "pomegranate-type" fireproof thermal insulation plate comprises 40-80 parts by weight of expandable polystyrene particles, 20-60 parts by weight of an inorganic surface-covering packaging material, and 2-10 parts by weight of a fire retardant, wherein the inorganic surface-covering packaging material is one or more selected from silica sol, sodium silicate and potassium silicate. The organic thermal insulation material in the fireproof thermal insulation plate is isolated by the inorganic material, and cannot drop, and therefore the fireproof thermal insulation plate has good fireproof effects. The invention also relates to a preparation method of the fireproof thermal insulation plate and a composite thermal insulation plate comprising the fireproof thermal insulation plate. The fireproof thermal insulation plate can be used as building materials.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a fireproof insulation board and a preparation method thereof. Background technique [0002] Polystyrene foam board is widely used in thermal insulation due to its low water absorption, light weight, high mechanical strength, and low price. At this stage, it has become the most widely used external wall insulation material in the world. [0003] However, general polystyrene foam boards are flammable materials, and they are easy to melt and drip when burned, and produce a large amount of toxic and dense smoke, which brings great hidden dangers to fire safety. At present, the flame retardant methods of polystyrene foam mainly include the following categories: 1. The method of adding flame retardants. This method is simple and direct, but it cannot effectively solve the fire prevention problem. 2. Copolymerize the flame retardant monomer with styrene to obtain polystyrene which i...
