Abstract

The present invention discloses a heat-insulating material made up by using magnesium oxide, magnesium chloride, polyurethane foam powder, sawdust, fly ash and modification reinforcing agent according to a certain mixing ratio. As compared with existent heat-insulating material, said invented product possesses the advantages of less heat loss, strong impact resistance, low cost, convenient construction and long service life, etc., not only can be used on the pipe line, but also can be used on the ball tank and roofing, etc..

Description

A kind of lagging material
The present invention relates to a kind of civil building material, especially relate to pipeline, the lagging material that spherical tank and roofing, ceiling use.
At present, the lagging material that pipeline, spherical tank, roofing, ceiling use has slag, fine coal charcoal, perlite, polyamine fat vacuole foam etc. substantially, and actual the use found, heat insulation effect is poor, thermosteresis is remarkable, is difficult for forming integral body, a little less than erosion resistance and the shock resistance, usually need repairing, life-span is short, and the comprehensive cost height is not ideal.
The objective of the invention is to provide that a kind of thermosteresis is little, corrosion-resistant, waterproof, protection against the tide, shock resistance, easy construction, the lagging material of long service life.
The object of the invention realizes like this, promptly select magnesium oxide for use, magnesium chloride, polyamine fat vacuole foam powder, sawdust, fine coal charcoal and modified and reinforced agent material, at normal temperatures and pressures, pass through stirring at low speed, when lasting whole process during 1/2nd times, dropping into modified and reinforced dose can use, and above material is according to described order, and the weight ratio of input is 1: 0.5～0.75: 0.2～0.55: 0.1～0.3: 0.1～025: 0.015～0.03, wherein modified and reinforced dose is by Resins, epoxy, vinylbenzene, third bronze medal and the assembly of cobalt naphthenate material form, and the weight ratio of order input is 1: 0.01～0.03: 0.02～0.04: 0.002～0.008 according to this.
The present invention is a main raw owing to selecting magnesium oxide, magnesium chloride and polyamine matter foam powder for use, compares existing insulation tree material, has shock resistance, and thermosteresis is little, and is anti-corrosion, waterproof, protection against the tide, easy construction, long service life, the advantage that comprehensive cost is low.
Further explain invention below by embodiment:
When dropping into 100kg magnesium oxide, the 75kg magnesium chloride at normal temperatures and pressures, all mix with the speed that per minute 300 changes, add 40kg polyamine fat vacuole foam powder again, 12kg sawdust, 15kg flyash, all mix 2.5 timesharing, drop into modified and reinforced dose of 2kg more at normal temperatures and pressures, continue all to mix 2.5 minutes, can use.Wherein modified and reinforced dose is mixed by Resins, epoxy, vinylbenzene, third bronze medal and cobalt naphthenate and forms, and the best of each material drops into weight and was respectively 1: 0.02: 0.03: 0.005.The lagging material that this example is produced, heat insulation effect improve 6-9 doubly, and thermosteresis reduces 28% than traditional lagging material, and impact resistance is carried 2-3 doubly, and comprehensive cost reduces 50%, reaches work-ing life more than 30 years.
