Description
Technical field
The present invention relates to insulation material, particularly to the processing technology of the outer fiberglass protective layer of a kind of heat-insulation layer.
Background technology
Existing part cryogenic equipment, has been desirable that one layer of fiberglass protective layer outside heat-insulation layer, and protective layer serves
Preventing steam from entering insulation material, preventing the effect of shock, existing fiberglass protective layer is all by manual
Method produces, and the technique that the present invention uses in hgher efficiency, appearance property more preferably to spray prepares fiberglass protective layer.
Summary of the invention
The purpose of the present invention, it is simply that in order to solve the problems referred to above, it is provided that the system of the outer fiberglass protective layer of a kind of heat-insulation layer
Make technique.
In order to achieve the above object, present invention employs techniques below scheme: the outer fiberglass protective layer of a kind of heat-insulation layer
Processing technology, the outer layer of described heat-insulation layer is RPUF, and fiberglass protective layer is coated on hard
On polyurethane foam plastics, processing technology comprises the following steps:
One, by unsaturated polyester resin 100 weight portion, accelerator 2-4 weight portion, firming agent 1-3 weight portion,
It is configured to spraying hybrid resin；
Two, at RPUF surface spraying ground floor hybrid resin；
Three, on ground floor hybrid resin, spray one layer of hybrid resin and the mixture of glass fibre again, form glass
Fiber-reinforced layer, method is to spray hybrid resin, simultaneously by the sand export ejection glass fibers on spray gun by spray gun
Tie up, and the weight proportion controlling hybrid resin and glass fibre is 100:10-15；
Four, offset glass fiber reinforced layer with compression roller made of glass fiber reinforced plastics, remove bubble removing and make hybrid resin sized glass fibres；
Five, at paving layer of glass surface, the glass fiber reinforced layer surface felt offseted；
Six, on the fiberglass surfacing mat offseted, second layer hybrid resin is sprayed；
Seven, with hair rotary broom, second layer hybrid resin and fiberglass surfacing mat are offseted, make hybrid resin infiltrate glass
Glass fiber surface felt；Ultimately form the fiberglass protective layer that thickness is 2mm-3mm.

Detailed description of the invention
The processing technology of the outer fiberglass protective layer of the heat-insulation layer of the present invention, is the outer layer rigid polyurethane foam at heat-insulation layer
Being coated with the processing technology of one layer of fiberglass protective layer on foam plastics, this processing technology comprises the following steps:
First pass through a GRACO 13:1 external mix chopped proportioner by unsaturated polyester resin 100 weight
Part, accelerator 2-4 weight portion, firming agent 1-3 weight portion, it is configured to spraying hybrid resin standby.
Before spraying, polishing of being polished in RPUF surface, and blow away surface dust.
Then the nozzle distance RPUF surface 65-75cm of spray gun is controlled, at rigid polyurethane foam
Foam frosting spraying ground floor hybrid resin；
Then on ground floor hybrid resin, spray one layer of hybrid resin and the mixture of glass fibre again, form glass
Fiber-reinforced layer, method is to use GRACO 13:1 external mix chopped proportioner, by spray gun ejection mixing
Resin, simultaneously by the sand export ejection glass fibre on spray gun, and controls the weight of hybrid resin and glass fibre
Proportioning is 100:10-15；
Then offseting glass fiber reinforced layer with compression roller made of glass fiber reinforced plastics, bubble inside removal also makes hybrid resin infiltrate glass
Glass fiber；
Then at paving layer of glass surface, the glass fiber reinforced layer surface felt offseted；
Second layer hybrid resin is sprayed again on the fiberglass surfacing mat offseted；
Finally with hair rotary broom, second layer hybrid resin and fiberglass surfacing mat are offseted, make hybrid resin infiltrate glass
Glass fiber surface felt；Ultimately form the fiberglass protective layer that thickness is 2mm-3mm.
The accelerator used in the present invention is cobalt naphthenate.
The firming agent used in the present invention is peroxide firming agent.
After resin solidification, by the method for randomization, cut out segment glass steel finished product from product surface, utilize trip
Whether the thickness of mark kind of calliper glass-reinforced plastic material reaches to design requirement.
By the method for range estimation, observe surface the most smooth, have the region of bulge, material is cut off and again
Make.
Measuring glass fiber reinforced plastic surface hardness with shore hardness instrument, whether hardness reaches more than D60.
