Description
Technical field
The present invention relates to field of heat insulating materials, specifically a kind of phenol formaldehyde foam thermal insulating material for flat-plate solar collector
Material.
Background technology
As the energy is increasingly in short supply and the continuous increase of environmental protection pressure, countries in the world all start to push exploitation renewable energy
Source, wherein solar energy are the regenerative resource utilized and exploitation is most wide, development prospect is best, and it is each to be widely used in each row
Industry, solar water heater industry are exactly one of them.China is richly stored with solar energy resources, and Solar use prospect is wide
It is wealthy, it has been that the first of solar water heater in the world uses state and producing country at present.
Plate type solar water heater is mainly by the part such as flat plate collector, storage tank, water pipe, support and accessory group
Into.Flat plate collector is the critical component of flat water heater, and its hot property height is the important indicator for weighing water heater quality, its
The effect of middle heat-insulation layer is to reduce radiating of the heat collector to surrounding environment, to improve the thermal efficiency of heat collector.Conventional thermal insulating material
Material has rock wool, mineral wool, polystyrene and polyurethane foam box phenol formaldehyde foam etc., and these insulation materials respectively have shortcoming, in reality
Also all occurs the problem of different in.For example, the fiber contained by rock wool, mineral wool can give production and workmen to cause one
Fixed injury, and its heat-insulating property is limited, easily comes off；Polystyrene can shrink when higher than 70 DEG C, can not be used alone, past
It is past to be used in mixed way with rock wool, mineral wool；Polyurethane heat insulation material can not be chronically among high temperature, and many manufacturing enterprises also without
Method overcomes more environmentally friendly floride-free foaming technique.
Phenol formaldehyde foam can preferably solve the above problems, and improve the performance and quality of panel solar.Phenol formaldehyde foam letter
Claim PF, be with many kinds of substance such as phenolic resin and emulsifying agent, curing agent, foaming agent and other auxiliary agents, foamed through scientific formula solid
Change the obturator-type rigid foam formed.Due to its extremely low thermal conductivity factor, good heat insulating, the king of insulation is described as.State
The phenolic board of outer production has preferable heat-insulating property, but domestic promotion efficiency at present is small, and production technology also more falls behind, its
Heat-insulating property is slightly worse than external product.The phenolic board of domestic production is there is easy efflorescence, mechanical strength is low, fragility, inextensibility
With the weakness such as water absorption rate height.In China, phenolic foam is at present in central air conditioner system, light thermal-insulation color steel, room
The fields such as room heat-barrier material, petrochemical pipe are applied successfully.
