Embodiment approach

[0012] Required equipment: 1. Reactor 2. Mixer 3. Foam barrel 4. JL-I sheet forming machine

[0013] Process:

[0014] 1. Pour 40kg of magnesium chloride, 50kg of water, and 0.3kg of ultramarine powder into the reaction pot and stir for 1 minute, then add 0.25kg of phosphoric acid and stir for 1 minute, then add 100kg of magnesium oxide, stir for 1 minute, then add 50kg of heavy calcium carbonate and stir until uniform spare.

[0015] 2. Put 0.3kg of foaming liquid in a foaming barrel, pour 10kg of water, and stir for about 5 minutes (when adding the foaming liquid, dissolve it with hot water and foam with water at the same time)

[0016] 3. Pour the foamed water into the reaction pot and stir for 15 minutes until it is completely stirred evenly.

[0017] 4. Slowly pour the prepared slurry into the JL-I sheet forming machine, add 4 layers of medium-alkali glass fiber reinforced cloth and flame-resistant polystyrene in turn, and automatically form it in the machine.

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

Technical field: [0001] The invention belongs to the field of new materials. Background technique: [0002] At present, there are several materials used for air ducts on the market, but they all have different defects: iron sheet is easy to rust; tin foil composite glass fiber material, aluminum foil polyurethane material is not strong enough, and aluminum sheet is too expensive. [0003] Purpose of the invention: [0004] In order to improve the deficiencies of the above air duct plate materials, the present invention proposes a new type of composite material that is environmentally friendly, energy-saving, light in weight, high in strength and non-combustible. Invention content: [0005] The composite material is composed of: high-strength environmental protection material and flame-resistant polystyrene foam material. The high-strength environmental protection material is composed of 10% to 20% of magnesium chloride, 40% to 60% of magnesium oxide, 20% to 30% of heavy c...
