Abstract

The new complex material for blast-pipe plate comprises: high-tension environmental friend slurry (10~20% magnesium chloride, 40~60% magnesium oxide, 20~30% calcium bicarbonate, 0.1~1% ultramarine powder, 0.2~1% inorganic foaming liquid, 0.1~0.5% phosphoric acid, and 10~20% water), four-layer Pt-interlace middle-alkali glass fiber reinforcement cloth, and slow burning polystyrene foam material. This product has well physical and chemical properties, and can also be used to decorate partition plate and ceiling with service time more than twenty years.

Description

Novel composite material for blast pipe sheet

Technical field:

The invention belongs to field of new.

Background technology:

At present, the material that the market upcast ventilation pipe uses has several, but all exists different defectives: iron sheet gets rusty easily; Tinfoil paper composite glass fiber material, aluminium foil polyurethane material insufficient strength, aluminium skin cost is high excessively.

Goal of the invention:

For improving the deficiency of above blast pipe board material, the present invention proposes a kind of environmental protection, energy-conservation, light weight, intensity is high and have non-flame properties advanced composite material.

Summary of the invention:

This matrix material by: high-strength environment-friendly material and the polystyrene foamed material of anti-the combustion are formed wherein the high-strength environment-friendly material by magnesium chloride 10%～20%, magnesium oxide 40%～60%, water-ground limestone 20%～30%, ultramarine powder 0.1%～1%, inorganic foamed liquid 0.2%～1%, phosphoric acid 0.1%～0.5%, water 10%～20% and the 4 layers of platinum shape medium-alkali glass fibre that interweaves strengthens cloth and forms.

Technological process:

Earlier the various compositions that the high-strength environment-friendly material is required add in the reactor successively and stir, after about 15 minutes uniform slurries are poured in the JL-I template material forming machine, add 4 layers of medium-alkali glass fibre and strengthen cloth and the polystyrene foamed material of anti-combustion the, machine-processed moulding.

This matrix material is the two-layer 2.5mm～10mm high-strength environment-friendly material that is up and down, and the centre is 6mm～100mm polystyrene of anti-the combustion.

Advantage and positively effect:

This matrix material has light weight, does not fire, sound insulation, every advantages such as cold, heat insulation, environmental protection.The blast pipe board smooth surface of making, smooth, frictional coefficient is little, and non-corrosive, not mouldy, cost is low, in light weight, intensity is high, work-ing life is more than 20 years, not only can do air duct board, also can be used for fitting up heat-preservation partition board, insulating board and top ceiling etc.

Embodiment:

Required equipment: 1. reactor 2. stirrers 3. foaming bucket 4.JL-I sheet-forming machines

The course of processing:

1. magnesium chloride 40kg, water 50kg, ultramarine powder 0.3kg pour reactor into and stirred 1 minute, add phosphoric acid 0.25kg then and stir 1 minute, add 100kg magnesium oxide again, stir 1 minute, add the 50kg water-ground limestone again and are stirred to evenly standby.

2. in a foaming bucket, put into expanding foam solution 0.3kg, pour 10kg water into, stir about 5 minutes (when adding expanding foam solution, dissolving and water is got blisters simultaneously) with hot water

3. the foaming water of accomplishing fluently is poured into the reactor restir extremely stirred in 15 minutes fully.

4. slowly pour the slurries of accomplishing fluently into the JL-I sheet-forming machine, add 4 layers of medium-alkali glass fiber successively and strengthen cloth and the polystyrene of anti-combustion automatic moulding in machine.

Claims

1. a novel composite material for blast pipe sheet is characterized in that: be made up of high-strength environment-friendly material and the polystyrene foamed material of anti-the combustion.

2. novel composite material for blast pipe sheet according to claim 1, it is characterized in that: the course of processing is: 10～20% magnesium chlorides that the high-strength environment-friendly material is required, 40～60% magnesium oxide, 20～30% water-ground limestones, 0.1～1% ultramarine powder, 0.2～1% the inorganic foamed liquid of accomplishing fluently, 0.1～0.5% phosphoric acid, 10～20% water add in the reactor successively, stir, after about 15 minutes uniform slurries are poured in the JL-I template material forming machine, added 4 layers of medium-alkali glass fibre then and strengthen cloth and the polystyrene foamed material of anti-combustion the, machine-processed moulding.

3. according to claims 1 described novel composite material for blast pipe sheet, it is characterized in that: environment-friendly materials are two-layer up and down, all thick 2.5mm～10mm.

4. according to claims 1 described novel composite material for blast pipe sheet, it is characterized in that: the polystyrene foamed material of anti-the combustion is positioned at the middle layer, thick 6mm～100mm.

5. according to claims 1 described novel composite material for blast pipe sheet, it is characterized in that: not only be used for blast pipe board, also can be used for partition plate and top ceiling etc.
