Abstract
The invention discloses a composite thermal insulation material which is coated on equipment required to be thermally insulated. According to the material, the inner layer is a perlite composite thermal insulation material, the middle layer is glass fiber reinforced plastics, and the surface layer is finish. The method for manufacturing the composite thermal insulation material comprises the following steps of: taking expanded perlite particles as an aggregate, adding a water repellent and an adhesive, uniformly mixing, performing pressure forming in a mold according to the shape of the equipment required to be thermally insulated, and drying and curing to obtain the inner layer in a drying furnace; pasting the glass fiber reinforced plastics on the outer surface of the inner layer; and finally, spraying the finish on the outer surface of the glass fiber reinforced plastics, coating the composite thermal insulation material on an oil field gathering and transportation pipeline and a well site water injection well pipeline, and thermally insulating the pipeline. The composite thermal insulation material is high in pressure resistance, high in shock resistance, excellent in water resistance and excellent in thermal insulation performance, the outdoor service life of the product is generally 3 to 6 years, and the composite thermal insulation material can be repeatedly and detachably used and has the advantages of convenience in construction, good thermal insulation effect, firmness, durability, static resistance, flame retardant property, thermal insulation, low maintenance cost, energy conservation, environment friendliness, cotton yarn conservation, easy gasoline removal and the like.
Description
Technical field
The invention belongs to outdoor equipment heat preserving and freezing protecting technology field, relate to the heat-preserving anti-freezing of line equipment, be specifically related to a kind of complex heat-preservation equipment and preparation and application.
Background technique
Existing insulation measure generally twines glass fibre cloth mopping more outward with rock wool, and remove winter later, not reproducible use; Rock wool and glass fiber are harmful in disassembly process; It is bigger to environmental hazard to remove the back, and the material thermal insulation property is general, water-proof performance is poor, and external form is not attractive in appearance.
Summary of the invention
In order to overcome the deficiency of above-mentioned existing technology; The object of the present invention is to provide a kind of complex heat-preservation equipment and preparation and application; The crushing resistance and the shock resistance of this equipment are significantly increased, and water resistance has also obtained thorough improvement, thereby heat insulation effect is guaranteed; Product general 3---6 in outdoor working life, but and repeated disassembled and assembled use.
To achieve these goals, the technological scheme of the present invention's employing is:
A kind of complex heat-preservation equipment; Be wrapped on the equipment that needs insulation, the equipment internal layer is the perlite compound insulating material, and the mesosphere is a glass fibre reinforced plastics; The top layer is a finish paint; Said perlite compound insulating material composition is: the expanded perlite granule of mass fraction 80%, and the hydrophober of mass fraction 1%, all the other are Bond.
The thickness ratio on said internal layer, mesosphere and top layer is 4000～3000:250:1
The particle diameter of said expanded perlite granule is at 0.15～3mm
Said hydrophober is silicone oil, and Bond is sodium silicate or water soluble phenol resin.
The present invention provides the method for preparing said complex heat-preservation equipment simultaneously, comprises the steps:
Step 1 is that the expanded perlite material of 0.15～3mm is an aggregate with particle diameter, adds hydrophober and Bond and mixes, and according to the profile of the equipment that will be incubated, compression and moulding in mould, 200 ℃ of baking and curing make internal layer in drying oven;
Step 2 is pasted glass fibre reinforced plastics at the outer surface of internal layer;
Step 3 is at glass fibre reinforced plastics outer surface topcoating.
Said compression and moulding is to carry out at 30 tons of press.
Said internal layer prepares in the process, ejects, ejects the back release after feeding in mould, compacting, the compacting and all in 15-20s, accomplish.
Said complex heat-preservation equipment is wrapped on oil field gathering and transportation pipeline and the well site water injection well pipeline, can be incubated pipeline, this moment, the interior layer thickness of complex heat-preservation equipment was preferably 24～80mm, and intermediate layer thickness is preferably 2～5mm.
Compared with prior art; The present invention have easy construction, high insulating effect, sturdy and durable, antistatic, fire-retardant, the heat preservation maintenance expense is low, energy-conserving and environment-protective, saving cotton yarn, gasoline, be easy to clean multiple advantages such as (use washing powder, washing agent promptly capable of washing), is a kind of novel heat insulation equipment that can be applicable to petrochemical industry.This insulation equipment is composited by the thermal insulating material of glass fibre reinforced plastics casing and die cast; Crushing resistance and shock resistance significantly are improved, and water resistance has also obtained thorough improvement, thereby heat insulation effect is guaranteed; Product general 3---6 in outdoor working life, but repeated disassembled and assembled is used.
Select for use this product can make the well site pipeline maintenance become convenient, can reduce the overall cost of heat preservation construction, the site environment after the construction is also cleaner and tidier.
Embodiment
Below in conjunction with embodiment the present invention is explained further details.
At first prepare the complex heat-preservation equipment, comprise the steps:
Step 1 is that the expanded perlite material of 0.15～3mm is an aggregate with particle diameter, adds hydrophober and Bond and mixes, and the expanded perlite granule mass fraction is 80% behind the batch mixing, hydrophober mass fraction 1%, and all the other are Bond.Wherein hydrophober is silicone oil, and Bond is a sodium silicate.
According to the profile of the equipment that will be incubated, with 30 tons of press compression and moulding, 200 ℃ of baking and curing make internal layer in drying oven in mould.In the preparation process, ejecting, eject the back release after feeding in mould, compacting, the compacting all accomplishes in 15-20s.
Step 2 is pasted glass fibre reinforced plastics at the outer surface of internal layer;
Step 3 is at glass fibre reinforced plastics outer surface topcoating.
To prepare gained complex heat-preservation equipment and be wrapped on oil field gathering and transportation pipeline and the well site water injection well pipeline, and can be incubated pipeline, this moment, the interior layer thickness of complex heat-preservation equipment was preferably 24～80mm, and intermediate layer thickness is preferably 2～5mm.
