A kind of pentamethylene polyurethane plastics frostproof froth n manufacturing device and production method, this method comprises the following steps:
It is that instrumentation tubes are placed on special equipment first, work tube end described in the position alignment of spray gun will store different
Cyanate liquid, polyol liquid, pentamethylene liquid, fire retardant holding vessel be individually positioned on workbench, then lead to respectively
It is 1 that weight fraction ratio is isocyanates by the scale for crossing respective metering pump, polyalcohol 1.5, pentamethylene 0.2, fire retardant
It is transported in mixing tube and is sufficiently mixed for 0.2 ratio；
After the mixing tube mixes four kinds of mixings, the mixture alignment instrumentation tubes are sprayed by the spray gun
It applies, as uniform circular motion of the instrumentation tubes on special equipment and horizontal uniform motion keep the mixture of spraying uniform
The outer surface for being sprayed on the instrumentation tubes, and moment solidifies, and the pentamethylene polyurethane plastics frostproof froth n layer of formation is close
Degree height, high temperature resistant, service life are long.
The utility model has the advantages that
1. the present invention is a kind of pentamethylene polyurethane plastics frostproof froth n manufacturing device, the structure is by isocyanate material, polynary
Alcohol, pentamethylene, fire retardant liquid be placed in respective holding vessel, and by metering pump by it is required proportion be added to mixing
It is mixed in pipe, mixture is sprayed to the outer surface of instrumentation tubes, the poly- ammonia with pentamethylene of formation finally by spray gun
The advantages that ester plastic foam foaming layer density height, high temperature resistant, service life length, supportive are strong, and thermal coefficient is low, and heat insulation effect is good.
The pentamethylene that the present invention uses has become the foaming agent of hard polyurethane foams, smelly to atmosphere for substituting
Gas-bearing formation has the chlorofluorocarbons (CFC5) of destruction, and ODP discharge value can make huge emission reduction to environmental protection close to 0 for 10DB
Contribution.
The original polyurethane insulation coating for being added without pentamethylene of polyurethane plastics blowing ratio of pentamethylene is added in the present invention, can
Enhance the density and intensity of polyurethane, high temperature resistant is up to 300 degree or more, and thermal coefficient is minimum to reach 0.027W/MK, and heat insulation effect is most
It is good, and usage amount seldom accounts for 4-5%, and cost is low.
The present invention is added minor proportion 4-5%'s in former polyurethane plastics frostproof froth n isocyanate material, polyalcohol
Pentamethylene composition and fire retardant, wherein the flame retardant materials are that expanded graphite either bromo fire retardant, the material have
Good flame retardation effect, it is high-efficient, it is easy to use the advantages that, while the great advantage of bromide fire retardant is good environmental protection, cost
It is low, have fire-retardant fireproof, it is mould proof, sterilize, go out it is full, remove peculiar smell, kill the feature of 99.99% or more great Jin bacterium, and its suitable for supplying
The energy deliveries pipeline field application such as heat, cooling supply, petroleum and petrochemical industry, ship.
The polyurethane insulation coating for the fire retardant that the present invention is added can reach B1 grades of fire-protection standards, meet holding for insulating layer
The quasi- GB/T29047-2012 of rower.
