Description
Technical field:
The present invention relates to steel pipe processing technique field, be specifically related to a kind of heating and cooling steel pipe heat insulation sheath fire retardant.
Background technology:
In heating and cooling induction system, conventional steel pipe is as conveying pipe, but steel pipe heat conductivity is strong, in order to avoid energy damages
Lose, it usually needs at conveying steel pipe outer wall, heat insulation sheath is set.Heat insulation sheath is many to be made up of polyurethane material, and its anti-flammability has
Limit, it is therefore desirable to additionally add fire retardant.For above-mentioned situation, our company develops a kind of heating and cooling steel pipe heat insulation sheath
Fire retardant, can not only significantly improve flame retardant effect, moreover it is possible to as filler, improve corrosion resistance and the water proofing property of insulation material.
Summary of the invention:
The technical problem to be solved is to provide one can not only significantly improve flame retardant effect, moreover it is possible to as
Filler improves the heating and cooling steel pipe heat insulation sheath fire retardant of insulation material corrosion resistance and water proofing property.
The technical problem to be solved uses following technical scheme to realize:
A kind of heating and cooling steel pipe heat insulation sheath fire retardant, is made up of the raw material of following parts by weight:
Volcanic ash 15-20 part, asbestos wool 10-15 part, wollastonite in powder 8-11 part, sulfur Gypsum Fibrosum powder 5-8 part, ceramic 4-6
Part, chlorosulfonated polyethylene 4-6 part, portland cement 3-5 part, epoxide coal bituminous 2-3 part, sulfated castor oil 1-2 part, nanometer three
Aoxidize two antimony 0.5-1 parts, nano lanthanum oxide 0.1-0.3 part.
Described wollastonite in powder needs through pretreatment before using, and its processing method is: 25-30 part wollastonite in powder, 4-6 part are gathered
Vinyl alcohol and 0.5-1 part nanometer rubber powder add in 3 times of parts by weight of ethanol, in microwave frequency 2450MHz, power after being uniformly dispersed
Microwave treatment 10min under 700W, adds 2-3 part cross-linking sodium carboxymethyl cellulose and 1-2 part polyvinylpyrrolidone, the most mixed
After conjunction continue microwave treatment 5min, gained mixture send into spray dryer, in prepared granule add 1-2 part spermol and
0.5-1 part nanometer titanium dioxide, last ground formation powder.
Wollastonite in powder, after pretreatment, on the basis of keeping original hardness and anti-flammability, reduces its intermolecular row
Repulsion, is effectively improved its viscosity, thus improves the mouldability of rubber sheath.
The invention has the beneficial effects as follows: the present invention, with volcanic ash as primary raw material, is aided with the auxiliary agents such as asbestos wool and prepares heat supply
For colod-application steel pipe heat insulation sheath fire retardant, this fire retardant can not only significantly improve the flame retardant effect of heat insulation sheath, improves insulation
The burning-point of sheath, moreover it is possible to as filling filler and the reinforcing agent of sheath, improve the corrosion resistance of sheath, water proofing property and mechanicalness
Energy.
